LETTERS PATENT to Henry Ball, Gun Maker, Great Russell Street, Birmingham, for the Invention of “Improvements In Repeating And Other Fire-Arms.”
Sealed the 27th October 1857, and dated the 30th April 1857.
(Void by reason of the Patentee having neglected to file a Specification in pursuance of the conditions of the Letters Patent.)
PROVISIONAL SPECIFICATION left by the said Henry Ball at the Office of the Commissioners of Patents, with his Petition, on the 30th April 1857.
I, HENRY Ball, Gun Maker, Great Russell Street, Birmingham, do hereby 5 declare the nature of the said Invention for “Improvements In Repeating And Other Fire-Arms” to be as follows:—
My Invention consists in constructing revolver fire-arms with single and double action locks of the several kinds herein-after described; also the method of connecting the barrel and lock frame; also the screw bolt that holds them together; also in a self -acting safety stop for the prevention of accidental discharge; also in compound self-acting spring stop or bolt for stopping and bolting the revolver; also in lever loading rod with sliding rammer and catch for the same; and, lastly, in the construction of a fire-arm designed for defensive purposes; all of which I will proceed to describe.
The first part of my Invention is as follows:— The cock works in a slot behind the revolver. It possesses bents and pull, and is cocked by the thumb;; the chamber lifter is attached to it, and also the stud for working the spring stop. The trigger is placed in advance of the cock; & bolt for the chambers may also be worked by the trigger.
I will now describe the second part of my Invention. The cock works in a slot behind the revolver. To the cock is attached, either before or behind the centre, a lifting catch, the opposite end of which acts in a bent or notch in the trigger or lever attached to the trigger. To the lever is attached the lifter which turns the chamber. The lever may be placed on either side the trigger.
The third part of my Invention is as follows:— The cock works in a slot behind the revolver; it possesses bents and pull, also stud for working spring stop; the chamber lifter is also attached to it. Before the cock in the under side of the frame is placed the trigger, the blade of which laterally is in section; to this is fitted a lever, with which the trigger acts in conjunction in the self -acting portion of the arm, and independently of it; in the cocking portion to the lever is jointed a double-ended sear or lifter, the upper end of which acts in bents in the cock or on projection on either side of it; the lower end is acted on either by the lever or trigger.’ The trigger blade is circled inside and outside. The arrangement of the bent in the cocking portion throws the lower end of the scear out of the inner to the outter circle.
The fourth part of my Invention is as follows:— The cock works in a slot behind the revolver, and has attached to it, either before or behind, the centre a lifting catch, which is acted upon by the guard or the lever acting in connection with it. The guard works upon a transverse pin in the middle of 25 the frame, and when presst throws back the cock and turns the chamber. A trigger attached to the guard or frame disengages the cock. The chamber lifter is attached either to the guard or lever. The guard I prefer is the spur kind.
I will now describe the fifth part of my Invention. At the breach end of the barrel, at the top, is continued a solid strap of any suitable length, on the end of which studs are cut, which fit into holes adapted for them near the top of the lock frame., On the bottom of the breach end of the barrel is a solid projection of any suitable length, the end of which is jointed by peg or mortice to the end of the projecting piece in front of the lock frame; these are held together by a screw bolt which passes through the centre from the front of the under projection, paralel with the barrel, and screws into the heading of the lock frame. The screw bolt also serves as axis, upon which the series of chamber revolve.
I will now describe the sixth part of my Invention. This consists in a self acting safety stop, which works upon a centre on the inner front of the lock box. The upper end acts under the cock head; the lower end is acted on by the trigger or scear.
The seventh part of my Invention consists in a compound self-acting spring stop or bolt for stopping and bolting the revolver; it works upon a transverse; pin. The spring end is acted upon by a stud in the cock, which lifts the bolt end out of its recess and allows the chamber to revolve; the cock rights itself by means of the elasticity of the spring.
The eighth part of my Invention consists in a lever loading rod with sliding rammer. The axis of the lever is at the lower end of the projection underneath the barrel. The hammer works upon an elevated angle paralel with the barrel, and is connected with the lever by a pin, which works in a slot or by a groove and stud, or a combination of both, and also in the stud catch and recessed hook or fork for retaining the rod in position when not in use.
The last part of my Invention consists in the construction of an arm designed for defensive purposes. It consists of a plate of iron or any other metal, of a suitable size, form, and thickness, which plate has a projection in the middle, to which is jointed a barrel; attached to the plate upon a centre is a cock, so 20 placed as to drop upon the nipple, which is screwed either in the barrel or the projection upon which it is jointed. A trigger is also attached to the plate by a centre, either underneath, over, in front, or behind the cock, which possesses suitable bents or notches; these with suitable springs constitute the arm. It may be made either to load at the breach or the muzzle.
