Revolving Breech-loading Fire-arms.

LETTERS PATENT to William Robert Lake, of the “International Patent Office,” No. 8, Southampton Buildings, Chancery Lane, in the County of Middlesex, Consulting Engineer, for the Invention of “Improvements In Revolving Breech-Loading Fire-Arms.”— A communication from abroad by William Herrick, of the City, County, and State of New York, United States of America.

Sealed the 24th September 1867, and dated the 3rd April 1867.

PROVISIONAL SPECIFICATION left by the said William Robert Lake at the Office of the Commissioners of Patents, with his Petition, on the 3rd April 1867.

I, William Robert Lake, of the ” International Patent Office,” No. 8, Southampton Buildings, Chancery Lane, in the County of Middlesex, Consulting Engineer, do hereby declare the nature of the said Invention for “Improvements In Revolving Breech-Loading Fire-Arms,” a communication, to be as follows:—

The said improvements relate more especially to pistols which have a revolving cylinder containing a series of charge chambers arranged behind a fixed barrel, and consist chiefly in the peculiar construction of the said cylinder, which is made in two concentric portions. One of these portions is fitted to slide forward over the inner portion or core, which revolves on a central pin or axis. The division of the cylinder extends only for a portion of its length. The rear portion of the charge chambers is formed half in the core and half in the outer portion of the cylinder, the said chambers being continued forward beyond the end of the core into the solid front end of the cylinder. The cartridges employed are of such a length as to extend into the said solid portion of the cylinder, which sustains the whole force of the explosion. The charge chambers are formed with a recess at the rear end to receive the rim or flange of the cartridges.

The said improvements further consist in providing the under side of the barrel in front of the cylinder with a longitudinally grooved projecting piece, which is formed with an inclined recess and arranged to operate in combination with a stud or finger on the centre pin or rod whereon the barrel is turned to release the sliding portion of the cylinder. The barrel is locked when the pistol is adjusted for firing by a spring catch secured in the projecting piece and arranged to take into the end of the breech frame.

The inner portion or core of the cylinder is formed with a flange which when the breech is closed fits closely to the outer portion of the said cylinder; this inner portion or core is fitted to turn freely upon the centre pin or rod, and is provided with a collar which extends into the stock, and is fitted with a key to keep the said core properly up to the back plate and prevent its moving endwise. The inner portion or core of the cylinder extends about half way through the same.

The outer portion of the said cylinder is formed with a recess extending about half way through to receive the core or inner portion, and the two portions are so formed that when the breech is closed the two halves into which the series of chambers is divided fit perfectly together and coincide exactly with the continuation of the said chambers formed in the solid portion of the revolving cylinder. The inner portion or core of the cylinder is furnished with a guide pin or key which fits a longitudinal groove in the outer portion and keeps the two halves into which the chambers are divided properly together. The latter is provided with a collar which turns upon the centre pin and extends into the projection on the under side of the barrel. A key or feather passed through the said projecting piece into a groove in the said collar unites the barrel firmly to the cylinder, but allows it to turn independently upon the centre pin or axis. The centre pin is firmly secured to the breech frame and extends through the cylinder and through the projecting piece on the under side of the barrel. The front end of the said pin is provided with a stud or finger which fits a longitudinal groove in the lower side of the said projecting piece. The said stud also fits an inclined lateral recess extending through the side of the projecting piece into the front end of the longitudinal groove. The rear end of the projecting piece of the barrel is furnished with a spring catch, which is arranged to enter a recess formed in the front of the breech frame and lock the barrel to the said frame in the proper position for firing. The said catch is formed with a knob or projection which is pressed inward when it is desired to receive the barrel. The latter may be then turned on its axis till the stud on the centre pin is in line with the longitudinal groove in the projecting piece; the barrel can then be pushed forward and will draw the outer portion of the cylinder away from the core or inner portion of the same; the empty cartridge cases can then be readily removed and the chambers filled with fresh cartridges; the barrel is then turned on its axis to the proper position for firing, and at the same time the inclined grooves acting on the stud of the centre pin forces the barrel back and brings the outer portion of the cylinder closely and securely in contact with the flange on the inner portion or core; the barrel is then locked by the spring catch and is ready for firing. The rotation of the cylinder to bring each chamber in line with the barrel is effected by the ordinary mechanism in connection with the cock or hammer.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by the said William Robert Lake in the Great Seal Patent Office on the 1st October 1867.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, William Robert Lake, of the ” International Patent Office,” No. 8, Southampton Buildings, Chancery Lane, in the County of Middlesex, Consulting Engineer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters Patent, bearing date the Third day of April, in the year of our Lord. One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign, did, for Herself, Her heirs and successors, give and grant unto 3 me, the said William Robert Lake, Her special licence that I, the said William Robert Lake, my executors, administrators, and assigns, or such. others as I, the said William Robert Lake, my executors, administrators, and assigns, should at any time agree with, and no others, from time to time and at all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “Improvements In Revolving Breech-Loading Fire-Arms,” upon the condition (amongst others) that I, the said William Robert Lake, my executors or administrators, by an instrument in writing under my, or their, or one of their hands and seals, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent.

NOW KNOW YE, that I, the said William Robert Lake, do hereby declare the nature of the said Invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement, reference being had to the accompanying Sheet of Drawings forming a part of this Specification:—

The said improvements relate more especially to pistols which have a revolving cylinder containing a series of charge chambers arranged behind a fixed barrel, and consist chiefly in the peculiar construction of the said cylinder, which is made in two concentric portions; one of these portions is fitted to slide forward over the inner portion or core, which revolves on a central pin or axis. The division of the cylinder extends only for a portion of its length. The rear portion of the charge chambers is formed half in the core and half in the outer portion of the cylinder, the said chambers being continued forward beyond the end of the core into the solid or undivided front end of the cylinder. The cartridges employed are of such a length as to extend into the said solid portion of the cylinder, which sustains the whole force of the explosion. The charge chambers are formed with a recess at the rear end to receive the rim or flange of the cartridges.

The said improvements further consist in providing the under side of the barrel in front of the cylinder with a longitudinally grooved projecting piece, which is formed with an inclined recess and arranged to operate in combination with a stud or fin on the centre pin or rod whereon the barrel is turned to release the sliding portion of the cylinder. The barrel is locked when the pistol is adjusted for firing by a spring catch secured in the projecting piece, and arranged to take into the end of the breech frame.

DESCRIPTION OF THE DRAWINGS.

Figure 1 is a side view of my improved pistol with the barrel and revolving cylinder adjusted for firing; Figure 2 is a side view of the said pistol, showing the barrel and cylinder adjusted for loading; Figure 3 is a section of the revolving cylinder on the line x, x, Figure 1. Like letters indicate the same parts in each of the Figures.

A is the stock, which may be of any suitable form and construction. The chamber a in the said stock is provided to receive the mainspring b, which is attached to the stock at the lower end of the said chamber by a screw c or other convenient fastening. The free end of the mainspring acts upon the friction roller d on the hammer e, which is held at full or half cock in the ordinary manner by the point of the sear f resting in either of the notches e^1, e^2. The inner portion or core g of the cylinder is provided with a flange g^1, which may be screwed upon a neck or projection g^2, as shown in Figure 1, or formed solidly upon the said core. When the breech chambers h are closed this flange fits closely to the outer portion i of the revolving cylinder. The inner portion or core g is fitted to turn freely upon the centre pin or rod j, and is kept up against the back plate k by the shoulder j^1 of the said centre pin, or by means of a collar extended into the stock and fitted with a tangent key in such a manner as to keep the part g from moving endwise. The inner portion or core g extends about halfway through the revolving cylinder, and the outer portion i of the said cylinder is bored or chambered to the proper length to receive the said core or inner portion. By making the core g shorter than the cartridges the accumulation of dirt between the two portions g and i is prevented; these two portions are so formed that when the breech chambers are closed, as represented in Figure 1, the two halves into which the chambers h are divided fit perfectly together, and coincide exactly with the continuation of the said chambers formed in the solid or undivided end of the outer portion of the revolving cylinder. The inner portion or core g of the said cylinder is furnished with a guide pin or key l, which fits a hole m or a longitudinal groove in the outer portion i and keeps the two halves g and i properly together. The outer portion i of the cylinder is provided with a collar i^1 which turns upon the centre pin j and extends into the projection n on the under side of the barrel B. A key or feather o passed through the said projecting piece into a groove p in the collar i^1 unites the barrel B said projecting piece into a groove p in the collar securely to the outer portion i of the said cylinder, but turn independently upon the centre pin or axis j. allows the barrel to The centre pin j is preferably formed with a screw thread j^2, whereby it is firmly secured in the back plate / or other convenient part of the breech frame A^1, a small screw q being inserted at the exterior of the screw thread to prevent the turning of the rod j. The latter extends through the cylinder and through the projecting piece n on the under side of the barrel B. The front end of the said pin is r provided with a stud or fin r, which fits a longitudinal groove s in the lower side of the said projecting piece. The said stud also fits an inclined lateral recess s^1 extending through the side of the projecting piece n into the front end of the longitudinal groove s. If found desirable two of these studs r, grooves s, and recesses s^1 may be provided. The rear end of the projecting piece n of the barrel B is formed with a chamber or cavity n^1 to receive the spring catch t, which is arranged to enter a recess u formed in the front of the breech frame A^1, and lock the barrel to the said frame in the proper position for firing, as shown in Figure 1. The said catch is formed with a knob or projection t^1, which is pressed inward when it is desired to release the barrel B. The pistol is loaded when the parts are in the position shown in Figure 2, the cartridges being inserted into the chambers h with their rims resting in the recesses h^1, and their ends extending into the undivided end of the portion i of the cylinder. The barrel B is then turned on its axis j to the position shown in Figure 1. The side s^2 of the inclined groove s^1 acting on the stud or fin r of the centre pin j forces the said barrel back and brings the outer portion i of the cylinder closely and securely in contact with the flange g^1 on the inner portion or core g. The barrel B is then locked by the spring catch t, and is ready for firing. To empty the charge chambers h, and reload the pistol, the barrel is released and turned on its axis till the stud r on the centre pin is in line with the longitudinal grooves; the barrel B can then be pushed forward, and will draw the outer portion of the cylinder away from the core or inner portion g. The empty cartridge cases can then all be readily removed, and the chambers A filled with fresh cartridges. The rotation of the cylinder to bring each chamber in line with the barrel B is effected by the ordinary mechanism in connection with the cock or hammer e.

Having thus fully described the said Invention as communicated to me by my foreign correspondent, and shown how the same may be conveniently and advantageously carried into practice, I wish it understood that I do not confine myself to any particular form or arrangement of the parts of the lock or devices for causing the rotation of the cylinder, nor to any of the details of construction relating to the barrel, stock, or other parts common to all pistols, nor do I claim any part of the same, but I claim,—

First, constructing the revolving cylinder in two portions, substantially as and for the purpose set forth.

Second, making the core or inner portion g of the revolving cylinder shorter than the cartridges employed therein, substantially as and for the purposes set forth.

Third, the inner and outer portions g and of the revolving cylinder with the chambers h, flange g^1, and recesses h^1, constructed, combined, and operating substantially as and for the purposes set forth.

Fourth, supporting the barrel B to turn and slide upon a centre pin or axis attached to the breech frame or stock to adjust the pistol for either loading or firing, substantially as described.

Fifth, providing the centre pin j with one or more studs or fins arranged to act in combination with grooves s and recesses s¹ formed in the projection n of the barrel, substantially as and for the purposes set forth.

Sixth, the spring catch t and recess u for locking the barrel in the position for firing, substantially as set forth.

Seventh, the parts g and i of the revolving cylinder, the centre pin j, with the stud or fin r, the barrel B with the projection n, groove and recess s, s^1, and spring catch t, the breech frame A^1 with recess u, constructed, combined, and operating together and with the other parts of a revolving pistol, for the purposes and substantially as set forth.

In witness whereof, I, the said William Robert Lake, have hereunto set my hand and seal, this First day of October, in the year of our Lord One thousand eight hundred and sixty-seven.

Breech-loading Fire-arms and Ordnance.

LETTERS PATENT to Andrew Wyley, of Barker Street, Aston Manor, in the County of Stafford, Geological Surveyor, for the Invention of “Improvements In Breech-Loading Fire-Arms, Including Revolvers And Ordnance.”

Sealed the 7th October 1864, and dated the 16th July 1864.

PROVISIONAL SPECIFICATION left by the said Andrew Wyley at the Office of the Commissioners of Patents, with his Petition, on the 16th July 1864.

I, Andrew Wyley, of Barker Street, Aston Manor, in the County of Stafford, Geological Surveyor, do hereby declare the nature of the said Invention for “Improvements “Improvements In In Breech-Loading Fire-Arms, Including Revolvers And Ordnance,” to be as follows:—

My improvements refer mainly to fire-arms in which the breech, or breech chamber is connected to the barrel by means of a screw having portions of the external and internal threads cut away, so that the one will slide longitudinally within the other, and then interlock by a partial turn.

I shall first describe a single gun constructed according to this Invention.

The rear of the barrel is formed or fitted with a breech case of the same shape as the breech case described in the Specification of a Patent granted to Andrew Wyley, and dated the 2nd of October 1861, (No. 2453,) and figured in Sheet I. of the Drawings attached to same, with the exception that it is much shorter, not extending further back than the screwed part, and has attached to its lower portion a lump of a depth equal to that of the wood of the stock. The breech chamber which for brevity I will henceforth call the breech, is also formed like that described and shewn in said Specification and Drawings, excepting that it is without the lever, and is firmly attached to the stock by means of a piece which takes the place of the ordinary break-off, and which may be called by that name. In this last the percussioning is placed. A back-work lock is used. The stock is divided in front of said break-off, and between the fore and rear parts a carrier or collar is placed, embracing that portion of the breech between the screw and break- off; it is furnished with a spindle at its lower part, travelling in a hole in the lump under the breech case parallel with the barrel’s axis. To open the breech the stock is turned one quarter round, by which the screw is disengaged; breech, collar, and spindle are then drawn back till the former is free of the breech case; they are then made to swivel to the right upon the collar spindle until the breech is so far clear of the stock that the cartridge can be introduced or withdrawn: the breech, is closed by reversing the above motions. I prefer as cartridge a pasteboard tube slightly turned in at the rear end, which is covered with any thin material permeable to the cap fire. The cartridge may be inserted a short way into the barrel, which is chambered out for that purpose, and the breech slid over its rear end; in this case the ball which projects from the cartridge may be mechanically fitting, or it may be placed in the breech chamber. To use loose powder a metal tube is inserted in the breech to form a permanent cartridge as it were. A spring stop is used to hold the breech in the locked position and in that of being withdrawn. A stop is also employed to act on the spindle and prevent its turning till it has been drawn out the requisite distance; by removing this stop the fore and rear parts of the fire-arm are separated for cleaning or packing. Instead of forming the breech in one piece with the break-off, I sometimes screw or otherwise fit the former into the latter, the percussioning being carried across the joint; thus central fire may be obtained, a steel breech hardened in oil, and tempered, may be conveniently used, and the carrier collar may be formed in one piece. I sometimes form the breech case of steel in one piece with a steel barrel, and harden and temper the former, occasionally including that portion of the barrel which is enlarged to receive the cartridge; for this purpose two heavy metal rings are used, fitting close to the barrel, one is placed on the barrel while being heated, and prevents the heat from extending up the barrel; the heat is got up as rapidly as possible, and the metal ring knocked off and replaced by a cold one.” In order still further to define the junction between the red hot and cooler portions of the barrel before it is immersed in the hardening fluid.

In the second mode of construction the lump under the breech case, collar, and spindle, may be dispensed with. Two straps are made to extend back- wards from the cheeks of the breech case carrying a couple of pins at their rear extremity made to project inwards in a line with each other. These pins work in grooves formed on opposite sides of the breech chamber, and permit of its being turned one quarter round so as to disengage the screw, and then withdrawn so far that it can tilt up out of the line of the barrel to receive the charge, oscillating on the above pins as centres, till it is stopped by the bottom of the breech case which is extended backwards beyond the cheeks. This construction is applicable to ordnance. The requisite motions are, in this case, given to the breech by a lever or handles at its rear end. In large guns holes are also made in which hand-spikes may be inserted. The lower part of the breech case forms a bed in which the breech slides when drawn back or pushed in. The position of the pins and length of the grooves are so regulated that when the breech is tilted up its rear overbalances its fore part, but when the charge is introduced the balance should be nearly even. I prefer to line the breech chamber with a tube of steel hardened in oil and brought to a low spring temper. The fore part of this tube projects and enters some way into the barrel or chase as in small arms.

In small fire-arms the breech chamber is moved by the stock to which it is attached, as in the first method of construction, I here for the most part make the breech case of circular outline, dispensing with the wooden fore end of the stock. A hollow covering piece may be attached to the break- off so as to improve the appearance of the arm. Pistols and walking- stick guns may be made on this construction; in the latter a handle at right angles like that of a hunting whip takes the place of the stock; in this handle a simple lock may be placed consisting of a main spring with a crank-shaped head striking directly on the cap. A sear acting as trigger engages in the cranked part.

The foregoing construction may be varied by fixing the breech case to the stock instead of the barrel, its position being reversed, the external screw being then on the barrel instead of the breech, the two pins in this instance are in advance of the breech case and work in grooves in the barrel; the chamber for the cartridge is mainly in the barrel, but extends a short way back into the rear of the breech case; the breech may be simply screwed into. the breech case by the stock as a handle, and the carrier and guide pins above referred to may be dispensed with, in which case the fore and rear ends of the fire-arm are connected by a chain or other flexible connection.

In double barrels the connecting screw is placed below the junction and consists of a bolt passing through a hole in the lower part of a strong break- off, the screwed part engaging in a lump firmly attached below the rear end of the barrels. Portions of the screw threads are cut away as before, so that when the bolt is turned one quarter round it may be drawn back in the lump, carrying with it the break-off and butt of the fire-arm, which are thus separated from the barrels far enough to permit the latter to swivel on the bolt to the right or left for loading. Stops are used to restrain these motions between the necessary limits. The barrels are made to enter the break-off, or vice versâ, so as to prevent lateral shifting. The charge chamber is formed mainly in the barrels, but it is preferred that it should enter the break-off a short way. A thimble of soft metal is placed in the rear of the cartridge (which may be either of pasteboard or thin paper), and crosses the joint; an opening is made in the rear of the thimble, covered with any thin material easily penetrated by the cap fire; this thimble may be replaced by an expansion tube permanently fixed in the rear of the barrels. When a lever is used to work the bolt it extends downwards from the head of the latter, which is made of a circular shape, having a seat in the rear of the break-off. The lower strap forming the trigger plate is bent upwards nearly at right angles and attached by screws to the break-off. A pin passing through the upright part of the strap is screwed tightly into the centre of the bolt head and gives additional strength.

The last is not required when the stock is made to act as lever, being attached to the bolt head. The break-off in this case forms a separate piece between the barrels and bolt head. Stops are used to restrict its motions. Single barrel guns may be made on this principle.

In order to take the bending strain off the connecting bolt, the break- off part may be continued forwards so as to form a body like that of the Lefaucheux gun. In this a round channel is formed, in which a lump of corresponding shape, attached to the barrels, slides sufficiently forward to permit of the introduction of the cartridge. The common pin cartridge may be used with this gun, but I prefer a cartridge made with a thimble as before described. The detonating priming is placed between two pins, one entering from the top the other from the bottom of the cartridge. A hole may be formed below the latter in that part of the charge chamber which enters the break-off. Into this it is driven by the blow of the hammer, and it serves to retain the cartridge while the barrels are being. drawn forward.

In this construction and wherever the lock action can be brought near enough to the break- off, I construct the lock as follows:— Instead of lock plates two short cheek pieces are screwed to the break- off; these carry the external arms of the tumblers while the inner studs are borne in a middle piece standing up from the lower strap. The main springs. are attached to the middle piece or lower strap. The sears, which form one piece with the trigger, are carried on pins screwed into the middle piece. The stock is cut away so that it can be fitted to the action without removing any part of the locks.

In revolvers the connecting bolt, the head of which is attached by straps to the stock, forms the spindle on which the chamber cylinder rotates; it screws into a lump formed below the barrel, which lump is continued downwards to form an abutment to diminish the lateral strain on the bolt. The barrel is formed with a conical lip or short tube at rear end entering some way into each chamber so as to break the joint, or each chamber may have a projecting tube entering a short distance into the barrel; when one of these enters the barrel the others enter a perforated shield attached to the rear of the latter, but which may in certain cases be dispensed with. When the handle or stock of the fire-arm is turned one quarter round the screw is disengaged, the bolt is then drawn back carrying with it the chambers till they are quite free from the barrel. The motion of turning the stock compresses a circular-shaped spring the fixed end of which is connected with the revolving chambers against one of the teeth of a ratchet on the head of the spindle. As soon as the chambers are clear of the barrel the re-action of the spring forces them round till the second chamber is opposite to the barrel or nearly so; a click spring or other stop holds them so until the tubular lip enters the barrel or chamber, as the case may be; the chambers are then pushed home to the barrel, and locked by a quarter turn of the stock,. as in the arms previously described. A stop is used as before to confine. the motions of the spindle and allow of its being easily withdrawn. The firm-arm may be cocked by hand before turning the stock or it may be made to cock itself by that operation. With a view to the latter, an arm or stud is made to project from the lower part of the tumbler, which, in revolvers, usually forms one piece with the hammer; it travels in a transverse groove in the hinder part of a scoop-shaped piece fixed, d to the shield or lump under the barrel, and extending backwards under the cylinder. The posterior side of the groove is inclined, so that the above stud, forced to travel against it, brings the hammer to half a full cock. Instead of this a strap may be fixed in the same way as the above scoop-shaped piece, but at one side of the cylinder; into a groove in the rear of this, the projection of the tumbler passes when the stock is turned round. Thus when the stock and cylinder are drawn back the hammer is cocked as before, the tumbler or hammer is pivoted low and as far forward as possible, the cylinder is removed from the barrel for loading, which is-done by hand; in some cases it is loaded by a lever ramrod of the 5 ordinary kind. Instead of a polychambered cylinder I sometimes use a pair of chambers only which are rotated by hand.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by the said Andrew Wyley in the Great Seal Patent Office on the 16th January 1865.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Andrew Wyley, of Barker Street, Aston Manor, in the County of Stafford, Geological Surveyor, send greeting.

HEREAS Her most Excellent Majesty Queen Victoria, by Her Letters Patent, bearing date the Sixteenth day of July, in the year of our Lord One thousand eight hundred and sixty-four, in the twenty-eighth year of Her reign, did, for Herself, Her heirs and successors, give and grant unto me, the said Andrew Wyley, Her special license that I, the said Andrew Wyley, my executors, administrators, and assigns, or such others as I, the said Andrew Wyley, my executors, administrators, and assigns, should at any time agree with, and no others, from time to time, and at all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “Improvements In Breech-Loading Fire-Arms Including Revolvers And Ordnance,” upon the condition (amongst others) that I, the said Andrew Wyley, by an instrument in writing under my hand and seal, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent.

NOW KNOW YE, that I, the said Andrew Wyley, do hereby declare the nature of my said Invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement, reference being had to the Drawings hereunto annexed, and to the letters and figures marked there on (that is to say):—

My improvements refer mainly to breech-loading fire-arms in which the breech or breech chamber is connected to the barrel by means of a screw having portions of the external and internal threads cut away so that the one will slide longitudinally within the other and then inter- lock by a partial turn; but some of the improvements are applicable to other breech loaders. They are illustrated in the accompanying Sheet of Drawings which I shall briefly describe.

Fig. 1 is a side view or elevation, and Fig. 2 a rear view of the action as used in the first method of construction in its closed state; Figures 4 and 3 corresponding views when open. In Fig. 3 part of the wood of the fore end and stock proper is shewn; Fig. 4 shews the cartridge e as introduced; Fig. 5 the collar C and spindle I; Figures 6 and 7 the stop pin E and spring F, the last three in perspective. Fig. 8 shews in partial section a modified form of the action, Fig. 1, C and I, being left out. The cartridge e^1 has a wooden or metal ring inserted in the rear to prevent collapse when withdrawn.

Fig. 9 is a side and Fig. 10 an end view of part of a field gun constructed on the second or centre swivelling method in its closed state; Fig. 11, a side view of same when open and loaded; Fig. 12^a shews in section a scoop-shaped piece q, which may be fixed to the break- off and nipple lump in small arms made on this principle, so as to cover the straps or brackets d^1, which are here forged or cast with the breech case.

Figs. 12 and 14 are side views of a preferable arrangement as applied to pistols. Fig. 12 shews the closed, Fig. 14 the open and loaded, state; Fig. 13 shews an elastic screw pin P^2 made with a slit and slightly opened out so as to have a better hold.

Fig. 15 shews in section part of a walking-stick gun, the breech of which is locked to the barrel in a similar way, but without the guide grooves and swivelling pins; Fig. 16 is a side view of the inverted action. Fig. 17 shews another form of same fitted with a bar lock. Fig. 18 is a sketch of a cartridge extractor.

The third mode of construction is shewn as applied to double barrels in Figs. 19, 21, and 23, which are partial sections taken mainly on the dotted. zig-zag lines shewn in Figs. 20, 22, and 24, which are rear views of the above actions. In Fig. 24 the trigger plate is shewn, but without the springs s and o. A wooden fore end is required for the form, Fig. 19, and may be fastened in any known way; Fig. 25 is a reduced section at the rear of the barrels in Fig. 23.

Fig. 26 shews in partial section the fourth or revolver construction; Fig. 27 a rear view of the action; Fig. 28, the recess in the bolt head, in which the actuating spring is placed.

Fig. 29 shews in plan the slotted end of the trigger plate, Fig. 23; Fig. 30 is a reduced perspective sketch of one of the forms used with a flange cartridge, and the extractor employed; Fig. 16^A is a reduced side view of a lock for a single gun, modified from that shewn in Fig. 23.

Fig. 23 , another modification for double gun.

In the first method of construction, Figs. 1, 2, 3, 4, 5, 6, 7, 8, the rear of the barrel is formed or fitted with a breech case A, similar to that described in the Specification of a Patent granted to Andrew Wyley, and dated the Second of October, One thousand eight hundred and sixty-one, No. 2453, and figured in Sheet I. of the Drawings attached to same, with the exception that it is shorter, not extending further back than the screwed part, and has attached to its lower portion a lump J of a depth equal to that of the wooden “fore end,” The breech chamber B, which for brevity I may call the breech, is also formed like that described and shewn in said Specification and Drawings, but it is without the lever, and firmly attached to the stock by: means of a piece D, which takes the part of the ordinary break-off, and which a may be so called. The charge chamber is usually carried a small way into D, in which the nipple or percussioning is so placed as to bring the fire as nearly central as possible. A backwork lock is used. In this form and in those to be described wherever B is of a length to contain the greater part of the charge, the same variety of ammunition maybe used as with the fire-arms described in the Specification above referred to; the paper-covered opening in the rear of the thick cartridges being sometimes made larger where the fire is not quite central. As such stout cartridges when exploded remain in B, and are not always extractable by the hand or by the teeth, an extractor, Fig. 18, is used; it consists of a plug, which enters into the cartridge, and has at its end a moveable jaw, which is made to bite it outside by drawing back the lever handle attached to said jaw, and then by a forward motion of the whole the cartridge is drawn. The jaw is kept open by a spring as shewn. The fore part of the cartridge may be lined with sheet brass. The stock is divided in front of D, and between the fore and rear parts a carrier or collar C is placed embracing a reduced zone of the breech between the screw and D; a spindle I screwed or driven into C travels in a hole in the lump J. The collar is made in two parts, joined by screws. To open the breech the stock is turned one-quarter round, by which the screw is disengaged. Stock, breech collar, and spindle are then drawn back and made to swivel to the right round the axis of I, into the positions shewn in Figs. 3 and 4, when the old cartridge is replaced by a fresh charge. The closing is effected by reversing the above motions. The cartridge e may be inserted a short way in the barrel, or as far as the chambered part will admit, and B slid over it. When exploded it remains in B, unless where the expanding lip is reversed, as shewn in Fig. 8; it here stays in the barrel, and is drawn by hand. The chamber in B should taper slightly towards D. When e or e^1 is first inserted in the barrel al mechanically-fitting ball may be used. A spring stop holds the breech when in the locked position, and that in which it is withdrawn Figs. 2, 3, 6, and 7. The pin E works in a hole in D, and is pressed by the spring F against the collar C, and when D is turned it falls into two holes corresponding to the above positions. The sides of the holes are sloped towards each other, so that E can rise out of them when the stock is forcibly twisted round Fig. 5. The spring F is placed in a recess in D, and held by its lower blade entering a dovetail, and secured by the lock-plate fitting against the projecting stud. The above stop maintains the position of D in respect to C, the last is prevented from turning when being drawn out, by having a flat formed on the spindle I, which flat works against the transverse bolt H; when fully withdrawn a gap cut on one side of I allows it to swivel to the right. H is only a strong form of the bolt used to connect the fore end to the barrel; its head should project so that it can be easily drawn to one side to allow the arm to separate: into two parts. The wooden fore- end is held by H and another bolt farther: forward, or by any known means. A hole is bored in it to admit the spindle, and fitted with a cork or india-rubber pad to receive the end of I. I sometimes screw or otherwise fit the breech into D, Fig. 8, the percussioning crossing the joint. Central fire is readily obtained, as when the breech is unscrewed the communication may be drilled more obliquely than usual. The collar C may be formed in one piece, an object which can also be attained by making the screw-joint in advance of C; this form also admits of the use of a steel breech, hardened and tempered in oil. I may here observe that I sometimes form the breech- case A or other part of the ” action ” as B, Fig. 16, in one piece with the barrel, both being of steel, and harden and temper such parts usually up to or a little beyond the fore part of the charge chamber. For this purpose. two heavy metal rings are used of a size to fit the heated barrel near the rear end. One, an iron ring, is placed on the barrel when in the fire, and prevents the heat extending too far. The heat is got up rapidly, the iron ring knocked off, and a cold ring of brass or iron. slipped on and turned round on the same part for a short time, in order still further to define the junction between the red hot and cooler parts of the barrel before it is immersed in the hardening fluid.

In the second mode of construction the parts J, C, and I are dispensed with. It is shewn as applied to ordnance in Figs. 9, 10, and 11. Two straps or brackets d extend backwards from A carrying the pins P near their rear end. The inner ends of these pins enter e grooves g when B is drawn back after. being unscrewed; when drawn back far enough B may be tilted up for loading oscillating on the pins P, until it is stopped by coming against the bottom part of B, a, Fig. 11. By prolonging a the tilting may be stopped at any angle from about thirty degrees to ninety degrees. The part a has its left-hand angle cut away a^1 so as to allow the screw threads to pass when B is unlocked; they are stopped by coming against the other angle a^2 ; when B is drawn back the screw slides in a as a bed. The requisite motions are: given to B by handles as shewn at its rear end, at the same time capstan holes are formed in the cylindrical button b, or a single hole is formed quite through it, Figs. 9 and 10, into which a strong steel-shod lever may be shipped when the gun is required for service. The position of the pins P and length of the grooves g are so adjusted that when Bis drawn out to its full extent its rear overbalances the fore part, so that it tilts without force; when the charge is introduced the balance should be nearly even. By changing the position of the parts ninety degrees B may be made to swing to one side instead of tilting, the lower bracket being more strongly attached. I prefer to line the chamber with a tube of steel hardened in oil and brought to a low spring temper, and driven as tightly into B as possible; the fore part projects and enters into the main tube of the gun, as in small arms; the elevating screw is attached to c.

In small fire-arms the breech B is moved by the stock to which it is attached, as in the first method. The brackets or straps d are made of one piece with A, the whole being preferably of circular outline, the fore end of the stock being dispensed with. A covering piece q, Fig. 12^a, may be attached to the break-off. But a better arrangement is shewn in Figs. 12 and 15, as applied to a small pistol, wherein the straps d are continued downwards forming a simple extension of the breech case, but without any screw cut in it. This part is so cut away as to allow the breech to tilt up to an angle of thirty degrees, or so far as to allow of its being loaded, as shewn in Fig. 14. Guide grooves g are cut for the pins P^2 as shewn. In larger fire-arms the nipple is placed further back, a backwork lock may be used and a divided stock, as in the first method.

In the walking stick gun, Fig. 15, a cross handle f takes the place of the stock. It is conveniently made of cast metal with a tubular ring f^1, which is fitted to a reduced part of the breech and fixed by the screw h. It is removable in order to introduce the lock, the principal part of which is a main spring k with crank-shaped head striking directly on the nipple. The trigger sear 7 is first placed in a recess in the neck of the breech; the main- spring is introduced into f, and the sear spring m attached, f is then fixed in its place, the sear spring being sprung over the head and eye of the sear.

In pistols or walking stick guns made without pins and grooves the breech is quite separated from the breech case in loading, but they are linked together by a chain or other flexible connection.

The foregoing construction may be varied by reversing the action, as in Figs. 16 and 17. The pins are in advance of the breech case or its screwed part, and work in guide grooves g^1 in the barrel. In Fig. 16 plain pins P^1 acted on by the spring F^3 are shewn working in shallow grooves g^1 deepening at the ends, B^1 may be screwed into the main part of the barrel with an escutcheon plate i between to cover the opening between A^1 and B^1. It may have a raised rim, as in Fig. 16, to retain a thin wooden casing, the fore part of which may be inserted in a hollow metal nose cap soldered to the barrel. Where no wood is used the barrel should have a projection below it to afford a good grip: The cartridge used for this gun may be the same as e^1, Fig. 8, or in place of a ring a short metal tube may be inserted, as shewn; its rear passes a considerable way into D; it is manipulated the same way. A steel tube may be used to cross the joint as e^3 in Fig. 21, when a skin or paper cartridge may be used. The percussioning is, as in the first method, the communication being drilled directly from the centre of the nipple seat, so that the fire can pass through the thin paper covering the end of the cartridge. If a cartridge is used with the arm Fig. 12 the same percussioning is used.

In double-barrels, as the connecting screw cannot well be placed on the barrels so as to take the strain directly, it is placed on a strong bolt T of hardened and tempered steel passing through a hole in a deep break-off, and engages in an internal screw in a lump O, firmly attached to the barrels below their rear end in any known way. In the Figs. 19, 21, 23, and 25 the said lump O, O^1, is supposed to be forged one-half with each barrel, and well brazed along the middle line. Portions of the screw threads are cut away as before, so that when the bolt T is turned one quarter round it may be drawn back in O, carrying with it the break-off and stock or butt of the fire- arm, which are thus separated far enough from the barrels to allow the latter to swivel on T to the right and left for loading in the forms shewn in Figs. 19 and 21, or to be loaded without swivelling, as in Fig. 23. The bolt H passing through a loop on each barrel, and working against a flat surface with suitable gaps formed on T, as shewn in Fig. 19, or a pin like P^1 or P^2, Figs. 14 and 12, the end of which enters a suitable groove g^2, Fig. 21, act as guides and stops to restrain the above motions within the necessary limits. The barrels are usually formed with cones or tubular lips to enter the break-off, or vice versa. The lip may be a steel tube e^3 firmly fixed in the barrel, Fig. 21, which admits of the use of a thin combustible cartridge. The cartridge e^2, Fig. 19, is similar to e^1, Fig. 8, but is fitted with a thimble of copper, brass, or charcoal iron long enough to cross the joint. If the cartridge is of thin paper the thimble should be of twice the length shewn in Fig. 19. When a lever is used to work the bolt T, as in Fig. 19, it extends downwards from the circular head R of the latter, which turns in a recess in the rear of D^1. The lower strap forming the trigger plate is bent upwards nearly at right angles in the form of a plate K^3 of an outline similar to D^1; K^3 is attached to D^1 by screws p^1. A strong pin p passing through and capable of turning in K^3 is screwed very tightly into the centre of R, and gives additional strength. In loading the right-hand barrel, which is then in the position shewn by dotted lines in Fig. 20, the lever is turned back into the locking position. The lever may be dispensed with, Figs. 21, 22, 23, and 24, the stock firmly attached by upper and under straps to the bolt head giving the requisite motion. The break-off D^2, D^3, is here a separate piece; to prevent R^1, Figs. 21 and 22, drawing away from D^2 a pin E^3 is screwed into the latter, and its end works in a groove g^3 in the circumference of R^1. In Figs. 23 and 24 the same object is attained by making the upper part of R^2 of a conically bevilled form ; the under strap being removed the bolt is inserted with the upper strap downwards and turned round into its place. A spring stop, shewn in Figs. 21 and 22, may be used; the spring F^1 presses the bolt E^1 into a hole in D^2, when the screw is locked E^1 is drawn back by the thumb-piece r.

In order to take the bending strain off the bolt, the break-off part D^3, Fig. 23, is sometimes continued to form a hollow body or bed L of the section shewn in Fig. 25. The barrels are shaped so as to slide along its upper part parallel to the axis of L, and are prevented from having lateral motion by the lump O^1 sliding in the tubular channel of L. The bolt T^2 attached to the stock as before engages in O^1; by a quarter turn it is unlocked, the barrels and lump O^1 are then free to slide forward far enough to admit the cartridge; O^1 is stopped by a closing piece L^1 fitted in the fore end of L. The trigger guard is so disposed as to come against the edge of the arched part of D^3 when the screw is fully unlocked and no other stops are required.

The cartridge e^4 , Fig. 23, is fitted with a metal thimble, and the percussion powder is placed between two pins u and u^1, the joint is covered by the short tube x, having a notch in front through which the composition may be introduced. A shallow hole w may be formed in D^3, into which the pin u^1is driven by the hammer, so as to draw the cartridge when the barrels are pushed forward; e^4 is finally removed by hand. The ordinary pin cartridge may be used, D^3 being left plain.

In this construction, and wherever the lock action can be brought near enough to the break-off I construct the lock as follows:— Instead of lock plates two short cheek pieces G^1 are screwed to the bolt head or break-off; these carry the external arms of the tumblers t, while the inner studs are borne in a middle piece M standing up from the lower strap, or extending between the lower and upper straps. The main springs S are attached to the middle piece M or lower strap K^4 as in Fig. 23; the trigger sears n^1 are carried on pins screwed into or passing through M, and are acted on by springs o, usually made in one piece with the mainsprings, or fastened by the same screw, as shewn in Fig. 23. The trigger sears, Fig. 23, are shewn as cranked, so as to bring the trigger blades closer together. The slots are cut from the end of K^4, see Fig. 29, and the gap thus left before the triggers when in place is filled up by a projection on R^2, through which the attaching screw passes. The screw is made large enough to grip K^4 on each side of the slot; if applied to a fire- arm, in which the stock is fixed to the break-off; G^1 and K^4 are also attached to the latter. The cheeks and trigger plate are attached to the bolt head, as indicated in Figs. 23, 24, so as not to break its outline or prevent its turning.

In revolvers, Fig. 26 and 27, the connecting bolt T^3, the round head of which turns in a recess in a cylinder, and is attached by upper and lower straps to the stock forms the spindle on which the cylinder N rotates. It screws into a lump O^2 below the barrel; O^2 is continued downwards to form an abutment S to diminish the lateral strain on T^3. The barrel is formed with a conical lip or short tube at its rear end entering some way into each chamber, so as to break the joint; or each chamber may have, as shewn in Fig. 26, a fixed projecting tube e^3 entering a short chamber in the end of the barrel. When one of these enters the barrel the others enter a perforated shield attached to the rear of the latter, of which S forms part. The action is as follows:— When the handle or stock of the fire-arm is turned one quarter round the screw is disengaged, T^3 is drawn back, carrying with it the chambers till they and as much of the charge as may project from them are clear of the shield and barrel. The motion of turning the stock compresses a circular- shaped spring V, Figs. 26 and 28. The fixed end of the spring, or what may be regarded as such is connected to N by the screw pin p^2 the other or free end is furnished with a click falling into ratchet-shaped notches in the reduced part of the bolt head. The spring being in the position shewn in Fig. 28, if T^3 is turned round to the left no compression takes place until the click falls into the first notch, further turning brings the spring into the position shewn by the dotted lines in Fig. 28. When the stock is drawn back as soon as the lips of the chambers are clear of the barrel, N is free to revolve on T^3 and the reaction of the spring V carries N round until the second chamber is opposite or nearly opposite to the barrel. The sloping side of the ratchet notches is made somewhat abrupt, requiring force to draw out the click, which counteracts the tendency to overshoot when the parts work freely. A spring F^2 Fig. 27, is used, and acts on a pin E^2, like that shewn in Fig. 7, which falls into V notches v in N to assist in bringing it up, so that a chamber is opposite to the barrel. Should N overshoot or stop short it is adjusted by hand. In relocking the screw the click of V is drawn out of one notch, passes over another, and nearly reaches a third, when it is in a position to act afresh. The head of the spring V^1 being screwed up to N by the pin p^2 keeps R^4 in its place The last is shewn as removeable, in order to get the spring V into place; or R^4 may form part of T^3, in which case R^3 is made strong enough for the reduced part of the bolt head to be screwed into it. A stop H is used to confine the motions of T^3, as in former constructions. The fire- arm may be cocked by hand before unscrewing, or it may be made self- cocking. With this view an arm or stud z is made to project from the bottom of the tumbler t^1. When the stock is turned to unscrew, z travels in a broad transverse groove U^1 in the hinder part of a scoop-shaped piece U, forged with or fixed to the shield or the abutment S. The posterior side of the groove is inclined, so that z being forced to travel against it brings the hammer to full or half cock, as arranged. Instead of this a strap X, Fig. 27, may be fixed. in the same way as U, but at one side of the cylinder. Into a groove in the rear of this the stud passes when the stock is turned a quarter round. When the stock is drawn back z is caught by X, and the hammer cocked as before. In this arrangement, as in turning the stock round to unscrew, the hammer is liable to catch, the nipples should project slightly beyond the recesses. The face of the hammer should be inclined on the left side, so as to spring over them, its lower part at other times travelling against the annular back of N. The hammer tumbler t^1 is pivotted as low and as far forward as possible. By withdrawing the stop the cylinder is removeable for loading, which is done by hand. In Fig. 27the shield openings are represented: as fitted with wooden plugs y, to prevent the bullets from coming out. The shield and plugs y may be dispensed with, in which case a lever ramrod maybe more readily used; metallic cartridges projecting from the chambers may be used, instead of the tubular lips, a strong jaw tool like that shewn in Fig. 18, but with the jaw on the opposite side being used to extract them. Instead of a poly-chambered cylinder, I sometimes use a pair of chambers only, which are rotated by hand, their lips entering in turn the barrel and piece S. The bolt acts the same as T^3; a pin takes into a groove in the head to prevent it separating from the chambers. The revolving and cocking gear are dispensed with, and an ordinary lock may be used, the percussioning being as in the first method.

Having now described several modifications of fire-arms constructed ac- cording to the above Invention, I would observe that I do not confine myself to these forms, which may be easily varied to suit circumstances. Thus, as examples in the first and second methods, the locking screw may have only two partial threads, if these are made strong enough. The construction shewn as applied to double is applicable to single barrels, the tie bolt, engaging in a strong lump forged on the rear of and below the barrel. The lever bolt T, Fig. 19, may be reversed, its screwed part engaging in D, or a fixed nut behind it. A guide pin may be screwed into D^1 working in suitable grooves in the plane part of T; the part D^1 may be made long enough to contain the entire charge; T is placed so as to leave room for the bolt head under the barrels, also the bolt T being a fixture projecting from the break-off, the locking may be by a round lever nut turning between O and a retaining piece below the barrels, and engaging with the screwed part of T, which is made somewhat smaller; or T itself may be placed lower, to allow of room for said nut. This construction is well suited for a flange cartridge, the break-off being made plane, and screwing up directly against the barrels. A suitable extractor Z is shewn in Fig. 30. The head fits into a recess in the barrel ends as usual, and the stem slides in a hole formed in the space between the barrels and bolt T^4. The lower part of the head is curved to fit T^4, and moves round it
with the barrels when the latter swivel to right and left for loading. A
circular transverse feather on T^4 enters a corresponding but wider groove in; the lower curve of the head, and draws the extractor and cartridges away from the barrels when the stock and T^4 are drawn back, the stock being turned sixty degrees to the right and left the cartridges are extracted by hand. A guide pin may be placed near the rear of O working in a T-shaped groove in the bolt. When the nut is unscrewed the lever is stopped by a projection on the barrel, or on O. Whenever a lever is used it should be held in one hand when barrels and stock are separated, or else it should work with considerable friction. The form, Fig. 21, is adapted to a flange cartridge by dispensing with D^2, the bolt head k^1 being made a plain break- off screwing up against the barrel ends, and retained by friction, or a spring stop. When the bolt is unlocked and drawn back the right-hand cartridge may be withdrawn. By turning the stock and bolt thirty degrees further in the same direction as before, the left-hand cartridge is exposed. An extractor similar to that above described is used. A spring stop like that shewn in Fig. 16 is used, a suitable guide groove being formed with holes deepening at the positions of loading and locking.

Flange fire and central fire cartridges on Schneider’s or any similar plan may be used. Needle fire and needle fire cartridges may be used with nearly every form of the fire-arm, the percussive arrangements being modified to suit.

The action shewn in Fig. 16 is applicable to the lighter kinds of ordnance, the breech case A^1 being fitted with levers instead of a stock. The lock shewn in Figs. 23 and 24 may be variously modified. Thus the middle plate M may be extended into a broad vertical blade M^1, Fig. 23^a, extending quite through the stock, till at some distance beyond the swivels it narrows abruptly, and is continued backwards in the form of a long taper tang entering far into the stock. The broader part may be thicker and ground out slightly hollow on both sides, the better to hold the wood which is screwed tightly up to it by a side pin passing through from cheek to cheek G^1; upper strap and trigger plate are dispensed with, being merged in M^1; the main springs are fixed to opposite sides of M^1 as to a lock plate, the tumblers as before the trigger sears extend downwards on each side of M^1, and may be straight or cranked outside the lower edge of M^1, in which a notch may be made, to allow of their back play. The gaps in the stock left for the sears to enter when the stock is driven up to its place may be filled up with block pieces screwed to M^1, or covered by a plate screwed to the lower part of M^1 In a single lock on this principle, Fig. 16^1, M^1 being as before, a round hole is cut in it large enough for the play of the tumbler and sear end, which hole is continued backwards far enough to admit the main spring, which may be fixed by a dovetailed foot entering M^1, the straight trigger sear is inserted through and works in a slot in the lower limb of M^1. The sear springs may in both single and double.forms be part of the main spring, or be fixed to M^1 in any known way. One arm of the tumbler is carried in a side plate as before, the other may mounted on an opposite side plate, or on a slip screwed to M^1 on the left side. A side pin is screwed into the right-hand cheek to make all fast as before. In the lock shewn in Fig. 16 the middle piece N, Fig. 23, is represented by a small plate standing up from the trigger plate, a little to the left of the central line, or extending back from the break-off D, which plate carries the inner stud of the tumbler and sear pin. The trigger sear passes through a slot in the trigger plate.

The arrangements in the above-described fire-arms which I claim as new are as follows:—

Firstly, as regards the first method of construction I do not claim the collar C with its spindle I and stop H; neither do I claim the method of locking the barrel and breech case to the breech by a screw in sections, as shewn, but what I claim is, the employment of such screw in connection with a collar and spindle placed as above shewn, the said collar being in the rear of the locking arrangement.

Secondly, I claim the employment of a similar breech-locking arrangement in connexion with guide grooves and swivelling pins mounted as set forth and shewn, also the particular constructions exemplified under the second head of this Invention, and shewn in Figs. 9, 10 and 11, 12, 14, 15 and 16.

Thirdly, I claim the application of the bolt T to closing the breech in double barrels or single guns, as above described and set forth, and the particular constructions by which it is exemplified.

Fourthly, I claim the application of a similar bolt to revolving fire-arms, and the mode of construction of the parts in connection therewith for revolving and cocking, shewn in Figs. 26, 27, and 28.

Fifthly, I claim the application to breech-loading fire-arms of the central locks with outside hammers, described and shewn in Figs. 23 and 24, with the modifications shewn wherever the locks can be brought moderately near to the break-off, and where the latter and the wood of the stock are of sufficient depth.

In witness whereof, I, the said Andrew Wyley, have hereunto set my hand and seal, the Sixteenth day of January, in the year of our Lord One thousand eight hundred and sixty-five.

Repeating Pistols and Rifles.

LETTERS PATENT to William Moore, of Birmingham, in the County of Warwick, Gun Maker, and William Harris, of Birmingham, aforesaid, Gun Maker, for the Invention of “An IMPROVEMENT IN REPEATING PISTOLS AND RIFLES.”

Sealed the 30th March 1853, and dated the 1st October 1852.

PROVISIONAL SPECIFICATION left by the said William Moore and William Harris at the Office of the Commissioners of Patents, with their Petition, on the 1st October 1852.

We, William Moore & William Harris, do hereby declare the nature of the said Invention for “AN IMPROVEMENT IN REPEATING PISTOLS AND RIFLES” to be as follows:—

Our Invention consists in the introduction of a hinge or other joint in the frame of repeating pistols or rifles, in which the revolving barrel works; that is to say, the single barrel, along which the projectile is urged by the explosion of the powder in one of the barrels of the revolving chamber, instead of being fixed to the frame in which the said chamber revolves, is connected therewith by a joint, so that the said single barrel may be turned upon the said joint from its place in front of the said revolving chamber.

The said joint may be in the upper or lower, or any other convenient part of the said frame.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by the said William Moore and William Harris in the Great Seal Patent Office, on the 31st March 1853.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, William Moore, of Birmingham, in the County of Warwick, Gun Maker, and WILLIAM HARRIS, of Birmingham, aforesaid, Gun Maker, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters Patent, bearing date the First day of October, in the year of Lord One thousand eight hundred and fifty-two, in the sixteenth year of Her reign, did, for Herself, Her heirs and successors, give and grant unto us, the said William Moore and William Harris, Her special licence, that we, the said William Moore and William Harris, our executors, administrators, and assigns, or such others as we, the said William Moore and William Harris, our executors, administrators, and assigns, should at any time agree with, and no others, from time to time and at all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “An Improvement In Repeating Pistols And Rifles,” upon the condition (amongst others) that we, the said William Moore and William Harris, or one of us, by an instrument in writing under our hands and seals, or under the hand and seal of one of us, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent.

NOW KNOW YE, that we, the said William Moore and William Harris, do hereby declare the nature of the said Invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof (that is to say):

Our Invention consists in constructing the frame in which the chambers of repeating pistols and rifles work with a joint, so that the barrel, along which the projectile is urged after leaving the revolving chamber, may be readily removed from the front of the said revolving chamber, so as to give facility in loading the said chamber; and by which said method of construction we also obtain the advantage of being able to connect the said barrel with the said revolving chamber during the discharge of the pistol or rifle, as herein-after particularly explained.

Figure 1, of the accompanying Drawing represents in vertical section

a pistol made according to our Invention; and Figures 2, 3, and 4, represent portions of the same. a, Figures 1, and 2, is the barrel, which is connected with the body of the pistol by the joint b, in the frame C. In Figure 1, the said frame, is represented closed; in Figure 2, the said frame is represented partly open by the disengagement of the fastening at d, and the raising of the barrel a, upon the joint b. The said joint b, may be made in any convenient manner; but we find an ordinary hinge joint, from the middle of which a portion has been cut away to admit of the action of the hammer, as seen in Figure 1, answer very well. On bringing the barrel a, into its place, the ends c^1, c^11, of the frame become connected together by the fastening represented, and which is made as follows:— e, is a spring, which bears against the side of the frame c; the said spring e, carries a stud f, having an inclined face, as shewn in dotted lines in the front view (see Figure 2). When the vertical side of the frame is brought down into its place, the end thereof presses back the said pin f, out of the frame, until the hole g, is opposed to the said pin f, when the said pin is forced into the said hole by the said spring e, and the fastening effected. By pressing on the button h, the pin f, is disengaged from the hole g, while the barrel a, and vertical side of the frame are raised. i, is a conical annular projection on the end of the barrel a, which is made accurately to fit the funnel shaped mouths of the detonating barrels k, k, of the chamber l, and against which projection the said mouths of the detonating barrels are forced at the moment of discharge in the following manner:— m, is a hollow fixed axis, on which the chamber l, rotates; the said chamber l, is keyed to the axis n, by a sliding key; the said axis n, passes through the fixed hollow axis n, into the interior of the lock, and carries on its end the disco, on the face of which a series of ratchet teeth are made; by pressing the trigger p, the arm or lever q, which is pressed against the face of the said ratchet by the spring r, engages with one of the teeth of the said ratchet, and moves the said chamber through one sixth part of a revolution, by which a detonating barrel k, is brought opposite the barrel a. The continued motion of the trigger brings the shoulder s, of the link t, against the end of the slide u, and forces the said slide against the posterior face of the chamber l, so as to cause it to slide on the hollow axis m, and axis n, and bring the funnel shaped mouth of the barrel k, to bear against the conical mouth i, of the barrel a, and thus, during the explosion, to constitute the two barrels one continuous. barrel. When the trigger has been moved to its full extent by the pressure of the finger, the shoulder s, of the link t, escapes from the shoulder v, of the trigger, and the hammer falls; but the slide u, is kept in its place by the pressure of the said shoulder v, of the trigger, which comes in contact with it at the moment when the shoulder s, of the link t, escapes from it.

When the hammer is again raised, the slide u, is forced back by the spring w, and the chamber l, is forced back, so as to disconnect itself from the barrel a, by the coiled spring x, forcing the plug y, against the anterior face of the chamber l. The posterior face of the chamber l, is formed into a series of inclined planes (see Figure 4), so that when the slide u, is pressed forwards, the said face, bearing against the end of the said slide, causes the said chamber to advance as it rotates, and gradually to bring the funnel shaped mouth of the detonating barrel close against, and at the proper moment force it into contact with, the projecting end of the barrel a.

By pulling the trigger to any extent short of what is necessary to discharge the pistol, and afterwards removing the finger from the said trigger, the cock or hammer is raised from the nipple z, and locked in that position until it is liberated by the further action of the finger on the trigger. The said locking of the hammer 1, is thus effected:— By partially raising the said hammer 1, the slide u, urged by the spring w, escapes from the shoulder 2, against which it previously pressed, and being shot by the spring w, under the said shoulder, the hammer can no longer fall to its full extent; the under part of the shoulder 2, bearing upon the top of the slide u. When, however, the trigger p, is pulled so far that the hammer becomes detached from it, in the manner already described, the slide is at that time pressed against the chamber 1, by the shoulder v, of the trigger, so that when the hammer falls, the slide U, on the finger being removed from the trigger, bears against the vertical face of the shoulder 2, of the hammer; and it is only after the hammer has been partially raised, that the slide u, assumes the position represented, by escaping underneath the said shoulder 2.

The advantages of our method of construction further consist of the completeness of the frame when closed, and the facility with which it can be opened to load the chambers or remove them; and also the facilities of manufacture which it affords; for, by the said arrangement, the moving parts in the body of the pistol can be more readily put together than when all the sides of the frame are made in one piece with the barrel; and when the said frame and barrel are in one piece, a defect in the barrel or frame may render the whole pistol useless; whereas, by our arrangement, a defective barrel may be replaced by a new one.

Another advantage of our method of constructing the frame is, that its front side has no connection with the axle or centre pin on which the chambers revolve; the cylinder containing the said axle being screwed into the back portion of the frame (or body of the pistol); and a frame so constructed can be better made to admit of the chambers advancing to interlock the concave mouth of each chamber with the fore barrel at the time of explosion.

The only precaution necessary, in opening the frame, for safely loading, is that of first placing the pistol at half cock, which is done by a partial pull of the trigger, or by placing the thumb upon the cock, in the usual manner of cocking.

Another advantage is, that the front vertical portion of the frame and the barrel may be made of twisted iron proper for barrels, while the body may be case-hardened, whereby it resists rust much better, and is, from its hardness, better for the action of the moving parts.

The barrel may, as heretofore, be either screwed into or on the front portion of the frame, or the front side of the frame may be made of the same piece of iron or steel as the barrel.

Having now described the nature of our said Invention, and the manner of carrying the same into effect, we wish it to be understood that we do not limit ourselves to the precise method of carrying our Invention into effect herein described, as the same may be varied without departing from the nature of our said Invention.

But we claim the construction of a hinge joint frame for containing the chamber of repeating pistols and rifles, whether the said hinge joint be situated in that part of the said frame herein described or in any other part of the said frame, whereby the several advantages herein described as arising from the said hinge joint frame may be realized.

In witness whereof, we, the said William Moore and William Harris, have hereunto set our hands and seals, this Twenty ninth day of March, in the year of our Lord One thousand eight hundred and fifty-three.

Constructing Revolving or Repeating Fire-arms, and Loading the same.

PROVISIONAL SPECIFICATION left by Thomas Pennell at the Office of the Commissioners of Patents, with his Petition, on the 29th April 1853.

(Void by reason of notice to proceed not having been given within the time prescribed by the Act.)

I, Thomas Pennell, of Birmingham, in the County of Warwick, Gun Maker, do hereby declare the nature of the said Invention for “Improvements In The Construction Of Revolving Or Repeating Fire-Arms, And In Loading The Same,” to be as follows:—

My Invention consists, firstly, in encasing the hammer and other parts of the locks of repeating fire-arms in a case, as shown at a, Fig. 1, as far as the said parts can be covered or concealed, consistently with their proper action. Secondly, in the method of connecting the stationary barrel with the frame of the pistol or rifle, as shown in Fig. 1, and in front view (partly in section) in Fig. 2. The barrel 6, separates from the frame at c; on being replaced, the axis d, of the chamber e, enters the hole f, and a pin formed on the end of the screw g, enters a hole in the frame h; the bolt 7, is then pushed in the direction of the arrow Fig. 2, and its inclined edge entering a depression k, in the axis d, of the chamber e, prevents the barrel 6, being withdrawn from the said axis. Thirdly, in loading the chamber of revolving fire-arms, as represented in side view, partly in section, in Fig. 3. In carrying this part of my Invention into effect, I make the part 7, in Fig. 1, of the form represented at 1, Fig. 3; and a hole m, Fig. 3, is made through the bolt, and that part of the barrel which is connected with the frame, as shown in the said Figure 3. When the ball has been put into the chamber, the lever o, is engaged under p, as shown; and by moving the said lever the ramrod q, forces the ball. down the chamber n; the said lever and ramrod can then be immediately removed. The end of the ramrod g, may be made into a nipple key, and the end of the lever o, into a turnscrew. In applying the first and second parts of my Invention to rifles, I connect the upper part of the case a, and the upper part of the stationary barrel, by means of a folding sight.

Anordningar vid revolvrar.
(Uppfinnare: A. Flock.)
Patent i Sverige från den 17 maj 1892.

Vid vanliga revolvrar minskas skottets precision betydligt, derigenom att det mellan pipans bottenyta och trummans främre yta befintliga mellanrummet, livilket är nödvändigt för att trumman skall kunna vrida sig utan att klämmas fast, äfven tinnes qvar vid affvrandet. Genom detta mellanrum kan dels en del af krutgaserna tränga ut och inverka skadligt på pipans rigtning, och dels hindras kulans rigtiga införande i pipan genom bristande styrning vid afbrottsstället; härigenom blef en god skjutning mycket försvårad.

För att minska dessa olägenheter liar revolvrar konstruerats, vid hvilka pipan varit förskjutbar längs efter i ramen och, i och för tätning af fogen mellan pipan och patron kammaren, kunnat dragas tillhaka före skottlossningen, sä att dess bakre ände gripit öfver patronhylsan.

Föreliggande uppfinning afser några anordningar vid revolvrar af sistnämda slag.

A bifogade ritning visas en enligt denna uppfinning anordnad revolver i tre olika lägen i tig. I, IIL och III.

I fig. I är den kring tappen 1 vridbara, under trycket af en fjäder 2 stående hanen 3 i hviloläget. Pipan 4 intager sitt främsta läge, lemiiande ett litet mellanrum mellan sin bottenyta och trummans 5 främre yta, så att det är möjligt att i och för laddning och urladdning vrida trumman omkring dess axel 6. Denna senare är skjutbar i längdrigtningen i ramen 7 och vid främre änden orubbligt förenad med pipan medelst muttern 8 samt i bakre änden försedd med en hakformig del 9. Mellan pipan och ramen är insatt en fjäder 10, som ändamälsenligast lägges omkring axeln 6 i en vid pipan fäst hylsa 11. Denna fjäder spännes genom pipans tillbakadragande och åstadkommer sedan dennes framåtförande.

Revolvern spännes genom att draga tillbaka lianen 3 eller aftryckaren 12.

Vid första tempot rör sig hanen och af tryckaren till det i fig. II visade läget. Ett stift 13 på lianen drager under denna rörelse axeln 6 tillbaka medelst den hakformiga delen 9. Samtidigt åstadkommer en näsa 14 pa hylsan 11 en vridning af vinkelhäfstången 15, hvarigenom den med denna ledadt förenade och under trycket af en vid ramen fäst fjäder 16 stående kringvridningsannen 17 kommer att glida öfver en tand pa den vid trumman 5 sittande kringvridningsskifvan 18 och lägga sig bakom densamma. Vid det i fig. 11 visade läget är spärrstiftet 10, som sitter på fjädern 16 och skall förhindra en oafsigtlig vridning af trumman 5. med säkerhet förd t ur baket 20; men livarje kringvridning af trumman förhindras ändock utaf pipan, emedan denna senare under tiden kmmit in i patronläget med sitt bottenstycke. Detta är pä främre sidan försedt med en kägelformig fördjupning 21, på det att det pä motsvarande sätt svarfvade bottenstycket lätt må komma in deri. Pipan skjuter sig vid tillbakadra gandet med loppet tätt öfver och omkring den del af patronhylsan 22, som når ut i den främre utvidgningen af patronläget. Under denna rörelse styres pipan i ramen af en styrskona 23.

Under det andra tempot förreglas pipan med ramen derigenom att stängerna 24 till regeln 25, som af fjädrarna 20 tryckos nedåt, med sina på baksidan killörmigt afsneddade ändar 27 gå in i motsvarande hål i styrskenan (se fig. V och VI), så snart lianen 3 eller aftryc karen 12 dragits tillhaka till läget i fig. II. Pipan gör dervid ännu en liten rörelse bakåt motsvarande kilen 27. I denna lilla rörelse deltager naturligtvis också axeln 6; stiftet 13 är frän läget fig. II till läget fig. III och tillbaka, såsom synes, ur ingrepp med axelns 6 hakfbrmiga del ,9, emedan stiftet såväl som hakens undre yta äro formade efter en cylinder, hvars axel sammanfaller med tappens 1.

Dragés aftryekaren ännu något litet tillbaka ur läget tig. III utlöses spärrarmen, hanen 3 springer framåt påverkad af fjädern 2, slår mot tändstiftet 2.9 och drifver det in i tändhatten. Efter antändningen trycker fjädern 30 tändstiftet äter något tillbaka, så att dess spets kommer ur patronhylsan. För att stiftet skall kunna gå undan bakåt, är hanens främre yta försedd med en liten skära. Släpper man loss aftryekaren efter skottet, så tryckes den af fjädrarna 20 till sitt hviloläge fig. I, stängerna 24 gä nedåt och släppa loss styrskenan 23, sä att pipan föres framåt utaf tjädern 10 och å sin sida åter lössläpper trumman. Afven näsan 14 har da rört sig framåt och fjädern 10 vrider vinkelhäfstängen 15 åt venster och trycker omvridningsarmen 11 uppåt, så att denne vrider trumman. Efter skedd vridning lägger sig spärrstiftet 19 i nästa hak i trummans omkrets och hindrar den att vrida sig vidare, tills vid nästa spännande pipan äter öfvertager denna funktion.

Medelst den beskrifna konstruktionen vinnes nu för det första att kulan redan i affyrningsögonldicket befinner sig i pipan, utan att dess styrning ett enda ögonblick afbrytes, och för det andra att krutgaserna pressa patronhylsans sidor mot loppets väggar och täta fullkomligt krutrummot.

Specification

To all whom it may concern:

Be it known that I, Ernst Paul, a citizen of the Kingdom of Prussia, and a resident of Wiesbaden, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Revolvers, of which the following is a specification.

The object of my invention is to provide an improved firearm which will also comprise a knife and serve as a thrust weapon; and the improvement consists generally in forming the butt-end of the pistol in two sections, one of which serves as a sheath for a knife, which may be at once thrown into position ready for use, and also to provide novel means for operating the blade by the single pressure of a button.

In the accompanying drawings, which illustrate the preferred form, construction, and arrangement of parts comprising my invention:-
Figure 1 is a side elevation of a revolver with the butt-sheath in longitudinal section.
Fig. 2, an end elevation thereof, looking to the front in the direction of the revolver sights with the butt-sheath in transverse longitudinal section.
Fig. 3, a side elevation of the knife-blade detached.
Fig. 4, a back edge view thereof.
Fig. 5, a transverse longitudinal section of the butt-sheath with the knife enclosed and secured therein.
Fig. 6, a similar view of the same with the knife projecting half its length from the sheath.
Fig. 7, a similar view of the sheath with the knife un sheathed to the full length of the blade and secured in such position.
Fig. 8, a plan or top view of the blade with the slot and enlargements at the ends thereof shown by dotted lines.

The drawings represent my invention applied to what is generally known as a “Colt’s Navy Revolver,” with the butt A or the butt sheath h forming part of the same, as hereinafter described, shown in section to receive a knife-blade a, the upper half or handle end b, of which is made flat and thin, with a division shoulder or thickness c between said knife-blade a, and the handle end b. A hole d, drilled through the shoulder thickness c, and a similar hole e at the upper end of the handle end b, are connected by a long narrow slot extending nearly the full length of the handle end b of the blade, and short stubs g upon one side of the blade project from the top edge of the thickness c upon either side of the slot f, and thus form the blade complete ready to be placed within the sheath h, and secured therein in the following described manner.

A small outwardly-projecting socket h’ and an inwardly-projecting stub i upon one side and a perforation h^2 upon the other side of the sheath in axial line with said socket h’ complete the sheath h ready to receive the above-described knife-blade and its operating connections. Two spiral springs k are arranged, one upon each side of the slot f in the knife-blade, to press or exert their tension between the stub i upon the inner side of the sheath h and the stubs g projecting from the top edge of the thickness c, thus to serve in firmly and truly pressing the blade out from the sheath with a quick forcible movement when it is released from the spanner l, which holds it therein. The spanner l is a short steel pin made to snugly fit the perforation h^2 in the sheath h, also to snugly fit the slot f of the blade, and having an enlarged hub l’ upon its inner end, which snugly fits the drilled holes d and e at the ends of the slot f of the blade, when they are respectively brought opposite the socket h’ in the side of the sheath h. The socket h’ holds a small spiral spring m’ which presses against the outer end of the enlarged hub l’ of the pin l and tends to press the said pin l outwardly to project beyond the outer face of the sheath h when not otherwise acted upon, as shown in Figs. 5 and 7 of the drawings, and which is accomplished only when the knife is held within the sheath be beans of a hub l’ engaging with the enlarged socket d in the middle of the blade, as shown in figure b, and when the said hub l’ engages with the enlarged socket d in the middle of the blade, as shown in figure b, and when the said hub l’ engages with the enlarged socket e at the end of the blade, and in the respective ends of slot f, as shown in figure 7, on which last named position the blade is securely held to project its full length out of the sheath, and can only be pushed back again into the sheath by pressing upon the pin l, until the enlargement l’ is pushed out of the socket e, and the blade being pressed against some unyielding substance permits the small end l of the pin to be moved in the slot f, as shin in figure 6, its full length, until the spring m again forces the large end l’ of the min l into the middle socket d in the blade, and securely holds the blade within the sheath against the pressure of the spring k above described. The spying m is of sufficient strength to prevent the accidental movement of the pin l when in the last named position, by pressing with sufficient force upon the projecting end of the pin 1, as is figure 5, the blade will be releases and the spring k will quickly force the blade out into the position shown in figure 7, and securely held be the pressure of spring m upon l, to force the enlargement l’ into the socket e, when they shall come opposite each other and hold the blade securely ready for use.

The knife becomes a powerful defensive weapon when the pistol is reversed, and the hand grasps the butt-end in such position that the knife will project forwardly from the clenched hand with the barrel of the pistol resting against and supported by the back of the forearm. Although my invention is shown as applied to a pistol, it may be similarly applied to the butt or handle of any small firearm; but it would be less convenient and also dangerous in its application to small arms to be handled by placing the butt to the shoulder without the employment of some safety attachment, readily suggested by one skilled in the art, as a screw-thread and nut upon the outer end of the pin l, to prevent the accidental discharge of the knife-blade from the butt-sheath while the latter is being held against the shoulder.

The exterior contour of the sheath h conforms to the shape of the half butt-piece p placed upon the opposite side, and both halves are made to conform to the shape of the steel frame-piece n, within which the elliptical spring o, of ordinary form, is placed for operating the lock mechanism in the usual way. The sheath half of the butt may thus at any time be removed and a butt-piece of any preferred material substituted therefor, or my attachment may be readily made to any revolving pistol by removing one of the side butt-pieces and substituting my sheath butt-piece of corresponding shape.

The knife becomes a powerful defensive weapon when the pistol is reverse, and the hand grasps the bitt end in such a position, that the knife will project forwardly from the clenched hand with the barrel of the pistol resting against and supported by the back of the fire-arm. Although my invention is shown applies to a pistol, it may be similarly applied to the butt or handle of any small fire arm, but it would be less convenient and also dangerous in its application to small arms, to be handled by placing the butt to the shoulder without the employment of some safety attachment readily suggested by one skilled in the art, as a screw thread and nut upon the outer end of the pin l to prevent the accidental discharge of the knife blade form the butt sheath while the latter is being held against the shoulder.

The exterior contour of the sheath h conforms to the shape of the half butt piece p placed upon the opposite side, and both halves are made to conform to the shape of the steel frame piece n within, which the elliptical spring o of ordinary form is placed for operating the lock mechanism in the usual way.

The sheath half of the butt may thus at any time be removed, and the but piece of any preferred material substituted therefor, or any attachment may e readily made to any revolving pistol by removing one of the side butt pieces and substituting my sheath but piece of corresponding shape.

I claim as my invention and desire to secure by Letters Patent-

1. A combined thrust arm and had fire-arm, comprising a butt-sheath, and a knife blade adapted to be held therein, substantially as described.

2. A combined arm, comprising a fire-arm, a butt adapted to receive a knife blade, and a spring held within the butt to act upon the blade, substantially as described.

3. A fire-arm, comprising a removable butt sheath conforming to a section of said butt piece, and a knife held within said sheath, substantially as described.

4. A sheath knife, adapted to fit the butt of a fire-arm comprising a casing h, a blade a b, having perforations d e, slot f and stub g, a spring k and a spanner pin l, substantially as described.

5. A sheath knife, adapted to fir the butt of a fire-arm comprising a casing h, having a socket h; and stub i, a blade a b having a slot d e f, and stub g, a spring k, a spanner pin and a spring m to fit the socket h’, and act upon the spanner, substantially as described.
