in the claim.

In the accompanying drawings, Figure 1 is an elevation of the breech, showing it closed. Figs. 2 and 3 are outer and inner side views of the magazine-lever 11; Fig. 4, a horizontal longitudinal section of the breech; Fig. 5, a longitudinal section through the slide 4. Figs. 6 to 9 are details of the nut 2 of the breechclosing case; Fig. 10, a longitudinal section of the breech with the magazine in place. Figs. 11 and 12 are longitudinal sections through the locking mechanism, showing it open and closed. Fig. 13 is a top view ofthe breech-block; Fig. 14, an elevation and horizontal section through the magazine. Fig. 15 is an elevation of the firing-pin; Fig. 16, a longitudinal section through cylinder 1; Fig. 17, an elevation of the same; Fig. 18, an elevation of breech-block 3, and Fig. 19 a longitudinal section thereof.

The letter A represents the breech-closing case that contains the breech-block 3. This block is provided with a continuous groove, which is straight in front, as at c, and of helical shape in the rear, as at (Z. The groove 0 cl is engaged by a lug h on aslide 4, that may be reciprocated in the usual manner by means of a suitable finger-piece.

The block 3 is provided at its rear end with the locking-tenons e, that are adapted to engage inclined grooves J and stops f on the breech-case A. The rearward motion of the breech-block is limited by a projection g on the tumbler-spring 9, Fig. 5. 8 is the firingpin having a socketZ back of projection h. To the firing-pin there isintimately connected by the socket Z the striking-pin 5, surrounded by mainspring 7. The forward end n of the breech-block is adapted to engage the cartridge on its forward motion and push the same out of the magazine into the barrel 1), as will be readily understood. The trigger is provided with a nose q, that engagesaprojection r of the striking-pin 5 to hold the same back.

1 is the locking-cylinder, having an annular collar 5, Fig. 13, that abuts against the breech block 3 and prevents the cylinder from retreating. The cylinder 1 is of tubular form to receive the firing-pin 8. At its rear end the cylinder is threaded to engage the nut 2, and at its center it is provided with the collar s. The breech-block 3 is'slipped over the cylinder and then the nut is secured in place, so that the block embraces and is free to turn on the cylinder. A perforation s in the rear part of cylinder 1 permits the lug h, passing through groove 0 d, to engage a projection s on the firing-pin 8.

6 is the extractor, having a claw t, that is adapted to enter the cartridge-shell to extract the same after the shot has been fired.

The striking-pin 5 is provided with a ring y, by which the pin may be moved back when the gun is to be cooked. Here it may be locked in a safety position by engagingalateral slot 2 of a nut 2 entering the end of the breechcase.

To adapt the breech to repeating-rifles, I employ a magazine 10, having a false bottom 13, upon which the cartridges are supported. The magazine is made in the form of a sheetmetal box of a size to hold any desired number of cartridges and adapted to bereadily attached and removed. The cartridges are introduced either one after another or in a bunch. The breech-case is provided with a strap 14, to which there is pivoted a lever 11, that engages the magazine and holds it in place. The lever is provided with an arc 70, having notches 12, adapted to be engaged by strap 14. To the magazine there is riveted a slotted guide 15, that receives a trunnion u on a shorter arm n of lever 11. \Vhen the are is pressed down, the strap 14 and the guide 15 will be released to release the magazine.

Fig. 14 illustrates a bunch of cartridges adapted to be introduced into the magazine and retained in place by spring-claws to within the same.

The operation of the device is as follows: In opening the gun the slide 4 is drawn back to cause the breeclrblock to turn by the engagement of the lug h with the groove 0 d. The shell will be loosened and moved back about two millimeters. The further rearward motion of the slide will cause the block to turn until the locking-tenons e have cleared the stops f. The breech-block 3, with cylinder 1, nut 2, and slide 4, can now be drawn b'aokward, which will cause the cylinder 1 to clear the cartridge-case. A cartridge is now introduced into the barrel from the magazine or by hand, WVhen the forward end it of cylinder 1 has arrived at the rear end of the barrel, the block 3 has turned ninety degrees, so that the lugs e cause the gun to be locked in its cocked position. WVhen the gun is fired, the cylinder 1 receives directly the pressure from the explosion. This pressure is by collar s transmitted to breech-block 3 and thence by lugs e to case A. During the forward motion of the breech-block its forward end engages the cartridge and pushes-it into the barrel. During this forward motion the tenons e, engaging the grooves 19, will first disengage the breech-block from the projection h. The nose q of the trigger will engage the projection 4" of the striking-pin 5 to hold the same back. WVhen the breech-block has moved forward up to about two millimeters, the barrel will be entirely closed, as the projection It will travel in the helical groove 61 and will cause the breech-block 3 to revolve around thelocking-cylinder 1. WVhen the projection 7?. has entered the straight part c of the groove, the block is effectively prevented from revolving any farther.

It Will be seen that my improved gun may be quickly put into firing order, avoids premature discharge, and may be readily set to rest. The breech may be taken apart and put together again without difficulty and without.

the use of tools. The device may be either used with a single charge or with a magazine.

What I claim is The combination of lock-case Aand slide 4, having projection h, with revolving breechblock 3, having projection e and grooves d, that is engaged by projection 71., and with locking-cylinder 1, that supports the breech-block and is provided with collar 3, substantially as Specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
