My improvements relate particularly to the extractor mechanisms of revolving fire-arms of the kind patented to C. A. King August 24, 1869, No. 94,003.
The barrel 1 of the arm is pivoted to the frame 2, so as to carry the lifter 3 in the joint. The finger 4 of the lifter bears against the end of the rod 5, to which the extractor 6 is attached at the other end. The cylinder 7 is supported upon the tubular pin 8, fixed in the barrel, and the extractor is retracted into the same, in the usual manner, by a spiral spring around its stem or rod 5. The construction and operation of these parts are well known, and will be readily understood without further description.
The extractor-lifter 3 is made in the form of a ring, Figs. 3 and 4, having the notch 9 on its inside edge. When in place in the joint of the arm, this ring 3 is mounted upon the hub 10, on which it is free to revolve, as hereinafter described. The hub 10 is a mere enlargement of the joint-pin 11 of the arm where it surrounds the same, and it is secured to the leaf 12 of the frame part of the joint by the screw 13, which enters the hole 14 in the hub, Figs. 1,5, and16. The frame carries the outside leaves, 12 and 15,of the joint,and the barrel the inside leaves, 16 and 17, of the usual construction, and the extractor-lifter revolves between the latter. In order to get the hub 10 into its place in the joint around the pin 11, the leaf 16 of the barrel part is bored out the size of the hub, while the opposite leaf is concentrically bored the size of the axial pin 11. The lifter 3 is then slipped edgewise into place between the barrel joint-leaves 16 and 17, and the hub 10 is passed sidewise through leaf 16 and the lifter. The leaves 12 and 15 of the frame part of the joint are now slipped into place outside of the barrel parts of it, and the axial pin 11 inserted in the usual way. The screw 13 is inserted through leaf 12 into hole 14 in the hub and the joint is complete. It will now be seen that the hub 10 always travels with the leaf 12 of the frame and axial pin 11 and forms an enlargement of the pin, around which leaf 16 of the barrel and the lifter revolves, while leaf 17 of the barrel revolves directly upon the pin 11. If this were all of the construction of the parts, the lifter would simply revolve around the hub 10 and have no means of actuating it to force out the extractor; but the alternating action of locking the lifter 3 to the hub 10 and releasing it after the extractor has ejected the cartridges is accomplished in the following manner:
Across the face of hub 10, which rests against the inner face of barrel joint-leaf 17, is cut a slot, 18, at right angles to the axis of the hub; In this slot is fitted a sliding latch, 19, made as long as the diameter of the hub 10. One end of this latch is formed into a square-edged nose, 20, capable of entering into the notch 9 of the lifter 3, and thus locking the lifter and hub 10 together. The latch 19 is a little wider at the other end than its groove 18 in hub 10, and has a slot, 21, cut through it to allow it to be sprung together and have a frictional bearing in the hub. The latch 19 also has the elongated hole 22 through it, to allow it to slide in the hub to and fro around the joint-pin 11, which passes through it. To properly move this latch in locking and unlocking the lifter 3 a pin part, 23, projects outward from its face into a curved slot, 24, in the barrel joint-leaf 17, Fig. 11. This curved slot is of a sufficient breadth radially to the joint axis to allow the pin part 23 to travel around in it whether the slide 19 be pushed out into the lifter 3 or drawn entirely back into the hub 10, and it has a cam-shaped bevel, 25, at one end of it, which, consing into contact with the pin 23, will push the latch 19 into the hub 10, and another carved slot, 26, at the other end, which, coming into contact with pin part 23, will push the latch out into the notch 9 in the lifter 3. The position of these parts is shown in dotted lines in Figs. 9 and 17.
The operation of the mechanism is as follows, the parts having been put together, as before described, with the latch 19 in its place in hub 10: When the arm is closed, as shown in Fig. 9, the cam-shoulder 26 of slot 24 in leaf 17 comes into contact with pin part 23. of latch 19 and pushes the nose 20 of the latch outward into notch 9 in the lifter 3. The lifter is now locked to the hub 10 and frame 2. When the parts are swung into the position shown in Figs. 1 and 2, the continued movement of opening the pistol will cause the finger 4 of the lifter to force out the extractor. When the barrel has been completely opened and the lifter has done its work, the cam-shoulder 25 strikes pin 23 and withdraws latch 19 into hub 10. This releases the lifter 3 from the hub and the extractor-spring causes the lifter to revolve backward around the hub to the position shown in Fig. 1 with relation to the barrel. The closing of the arm repeats the movements, as before described.
Figs. 10 to 17 show the additional feature of a cam added to the device, whereby the barrel of the pistol may be opened and swung down without extracting the cartridges in case it is desired to inspect them before discharging the pistol. In this construction a portion of the thickness of the annular part of the lifter is removed and the disk 27, of proper thickness to fill up this part cut away, is introduced between the lifter and barrel joint-leaf 17, the hub 10 being also shortened sufficiently to admit the disk. This disk 27 revolves on the joint-pin 11, which passes through its central hole, 28, and it has a spur, 30, on its periphery to turn it by with the finger. Through it, opposite to the slot 24 in the barrel hinge leaf 17, is cut a slot, 29, to allow the pin part 23 of the latch 19 to pass through the disk into the slot 24, as before described, and as shown in section in Fig. 16. On one side of the slot 29 it terminates in a cam-shaped bevel, 31, so proportioned that when the disk 27 is revolved and this bevel is brought against the pin part 23 of latch 19, as shown in Figs. 14 and 17, the latch will be pushed into the hub 10 and the lifter unlocked therefrom.
When it is desired to open the barrel without extracting the cartridges, the barrel is to be opened as far as shown in Fig. 1 and the disk 27 turned by the spur 30 from the position of Fig. 14 to that of Fig. 17, which withdraws the latch 19 into hub 10, and the arm may continue to be opened without operating the extractor-lifter.
In case the disk 27 is not moved the operation of the lifter and its release will be effected precisely as before, as the disk can never operate to unlock the lifter automatically. The disk 27 might be made to revolve around the hub10 and have bevels or spurs to operate on the end of latch 19, if desired, instead of against the pin part of it.
Figs. 18 to 28, inclusive, show another form of unlocking device for the extractor-lifter. In this construction all the parts are similar to those first described, except the pivot-pin 11 and the hole 22 through slide 19, the latter being made square at one end instead of oval. The pivot-pin is made tubular with its head countersunk. Through its wall, across one side, is cut the slot 35 transversely. From this the longitudinal slot 36 is cut through its wall toward its head. The slot 35 is opposite the slide 19 in the joint and allows the square end of hole 22 in the latter to enter it, as shown in Fig. 23. The plunger 37 is introduced into the pivot-pin 11, as shown, and the steel cam-piece 38 is slipped into the mortise 39 in the plunger, thus securing the latter into the pivot-pin 11. The pivot- pin being inserted through the hub 10, the cam-piece cannot escape. The screw 41 is then screwed into the open point end of the pivot-pin 11, with the spiral spring 42 between it and the plunger 37, thus securing the parts together. When it is desired to draw back the latch 19 into hub 10, the outer end of plunger 37 is pressed upon by the finger and the bevel 40 of the cam-piece 38 forced against the square side of the hole 22 in the latch 19, thus unlocking the lifter from the hub 10 and preventing its acting upon the extractor. It will be observed that in this construction of the latch for locking the lifter to the frame part 2 of the arm the latch is operated in both directions by cam-shoulders on the barrel part of the arm, while it is Mounted in and carried by the frame part 2 thereof, the hub 10, in which it works, being but an attachment to the latter. By my change in the location of the latch 19 and operating it positively in both directions by the cam-shoulders 25 and 26 of the barrel part of the arm I am not only able to dispense with any spring to operate it, but I inclose it entirely within the lifter and leave no joint exposed to being fouled up by dirt or gases of powder around it, and the construction is neater and better than when the latch is exposed at either one or both ends during its operation.
