RECOlL-OPERATED FIREARM.

SPECIFICATION forming part of Letters Patent No. 520,752, dated 29, 1894. Application filed April 24, 1890- Serial No. 849,211- (No model.)

To all whom it may concern.-

Be it known that-I, ANDREW BURGESS, a citizen of the United States, residing at Owego, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Automatic and Magazine Guns; and I do declare the following to be.

a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to automatic and magazine fire arms of all sizes and modes of mounting, and has for its object, ease and facility of operation, and consists of recoil breech working devices; magazine feed, and other arrangements and combinations of parts hereinafter described.

Figure 1 is a longitudinal sectional elevation of an arm having these improvements, with breech closed. Fig. 2 shows details of Fig. 1, with barrel and lever recoiled. Fig. 3 is a bottom plan view of barrel. Fig. 4 is another bottom view showing position of nonrecoil mounting on the barrel. Fig. 5 is a modification of Figs. 1 and 2 having a single central counter recoil spring. Fig. 6. is a cross section (enlarged) on line ac-.r of Fig.-

1; Fig. 7, an enlarged vertical cross view of the rear of the barrel and magazine. Fig. 8 shows the magazine follower. Figs. 9 and 10 are detached views of the magazine feeder. Fig. 11 is a modification showing a mode of using the recoil and lever, to operate a vertical breech piece, as applied to ordnance (reduced view).

Similar figures of reference indicating corresponding parts, 1 is the barrel, 2 the breech piece, 3 the non-recoil frame or mounting,4 the operating lever, and 5 the counter-recoil springs.

The frame or mounting 3, supports the barrel which has a limited longitudinal movement (guided by grooves) in said frame. An extension 6 of the barrel hasamortise or projection to engage the lever 4,,which is pivoted in the frame and has a long arm connected to the slide 7. The slide 7 is connected to an spring 12 may bear the lever 4 forward. At

the mouth of the magazine 18 is hung the vibrating spring feeder 13, which has

points

14 and 15 to engage the cartridges and follower 17 in the magazine, and an incline 16 which the closing bolt engages to vibrate it. To operate this arm first open the breech by bearing backward on the split thumb piece 25. This will move back the slide 7 which.

first unlocks the breech bolt by turning down the rear end of the locking brace 9, from abutting against its locking shoulder 21, of the barrel portion of the gun. Continuing the motion rearward the breech and lever obtain the position shown in Fig. 5,.the hammer cocked (from impact of the bar 6 against the pin. 22) and further secured by the safety dog 11. The magazine may then be charged through top or bottom'of the frame, and another cartridge inserted into the barrel, when let go the thumb piece, and the breech will close by force of springs 5 and 12 which bear the barrel and lever 4, forward, and the gun may then be fired by pressing against the safety dog 11 and pullingtrigger. When the recoil occurs the barrel is driven violently back to position shown in' Figs. 2 and 5, its

extension 6 turning the lever 4 on its fulcrum or pivot, and by reason of its engaging near the pivot of said lever carries its'to'p back more rapidly and farther than the barre], and the top of the lever engaging in the mortise of the slide 7 moves it back to open the breech as'before described( It will thus be seen that while the breech piece partakes of the recoil movement of the barrel, it has also an independent movement of its own, and the breech locking mechanism. also has an independent movement, all being actuated by the recoilof the barrel, or the-barcloses the breech as described, and drivingthe cartridge before'itis rady to'fire again.

In the modification, Fig. 11, the lever 4 is shown in hell crank form .to operate a .vertically moving breech piece by the same rearward recoil movement ofthe barrel and rehand when when reacted'upon by the springs? sistance of the spring 5 and mounting 3 and a spring catch 26 then holds the barrel in its rear position to allow the gun to be loaded by releasing the catch the barrel will be forced forward (by its heavy' spring 5) and the forward abutment of the frame extension 6 arrests the lever to vibrate it and thereby close the breech.

I show in dotted lines in Fig. 11 a reversal, in which the barrel maybe hung on the trunnions 23,'and the forward. ring of the heavy piece 3 moved forward, and the rear arm of the operating lever iturned upward. In this construction the inertia of piece 3 prevents it: from taking thequicki backward impulse of the barrel which'compresses the spring 5, sub-I stantially as before, and operates the lever to" move the breech through its np-turned arm I In horizontal magazines that feed the cartridges backward as here shown a shoulder has usually contracted the delivery end, so that the follower which is then 'larger than the cartridge head may not run out, and the magazine has to be made larger than otherwise required. By the construction here shown the magazine is made a true cylinder of only the size required for holding the cartridges and the oscillatingfeeder has the rear projection 14, to hold the head of the cartridge'or the I follower in,by being pressed behind it by the spring 30. When the projection 14 is retired by the movement of the breech or any of its connections (the bolt is here shown striking the incline 16 of the feeder to vibrate it) the rear'cartridge is free to pass rearward, but the next'one is engaged and held in by. the forward projection 15 which by above movement of the feeder has been turned inward, and when the feeder is released to spring back to the position shown in Fig. 7 the cartridge is released also from the point 15, and springs rearward to be caught and held by the point 14 so that the cartridges can feed but one at a time. The follower is first stopped in the same manner by 14 but when released bythat, as aforesaid the point 15 enters its annular groove to still hold it in the magazine, and the feeder thus holds the follower 'in by one of its points, however vibrated.

I claim- 1 1. In a fire-arm, the support or non-recoil portion,the barrel and connections constituting the recoil portion, the breech piece anda lever connected to the breech piece actuated cartridge by-the recoil portion to open the breech by thedirect recoil movement, all combined substantially as described.

2. In a firearm, the support or non recoil portion, the barrel and connections constituting the. recoil portion, non recoil portion and in the path of recoil of the recoil portion, the breechblock, and its locking piece, and connections from said lever to said locking piece, whereby the lever is moved by the movement of the recoil portion on firing, and said lever movement opens the breech, all in combination substantially as described.

3. In a firearm, the support or non-recoil portion the barrel and connections constituting the'recoil portion, the breech block and its locking mechanism, and a lever connected to the gun and actuated by the relative movement of the parts during recoil, said lever connected to the locking mechanism to open the same by the recoil movement, the parts being combined substantially as described.

4. In a gun the supporting non-recoil por 'tion, the barrel and breech piece connected substantially as described to move with differential movement under the force of recoil, jthe' spring acting on the barrel against the force of. recoil and tending to restore the same to normal position, "and a catch engag- "iiigtherecoil arts to retain said spring compressed and t e barrel open, all combined substantially as described.

5.
