ib al whom it may concern:

Be it known that l, Gronau S. Lnwrsaa citizen of the United States, residing in -Chicopee Falls, Hampden county, State of Massachusetts, have invented certain new and useful improvements in Magazine- Guns, of which the following is a specification, reference being had to the accompanying drawing, which forms a part hereof.

This invention relates to so-called pump guns, in which the operations of ejecting the empty cartridge shell, placing a' fresh cartridge in the chamber of the barrel, and cooking the gun in readiness for firing are usually accomplished by longitudinal reciprocating movements of a fore-endor grippiece which slides on a magazine tube below the barrel and is connected to the breech mechanism by a slide-bar. The grip-piece or fore-end necessarily has a predetermined range of movement in order that the several operations may be accomplished and the guide or magazine tube upon which 1t moves necessarily has a certain definite length. Ordinarily the guide or magazine tube has a length sutlicient to hold five or more cartridges and it is the special object of this invention as applied to the construction shown to provide means to limit the number of cartridges which it is possible to place in the magazine while retaining the length of the magazine tube or the guide for the foreend or grip-piece required for the proper operation of the gun, without making necessary a reorganization and reconstruction of the gun.

The generaltobject of the invention, however, is to provide means for limiting the number of cartridges which it is possible to place in any form of magazine without changing otherwise the pattern of the gun.

The invention will be more fully explained hereinafter `with reference to the accompanying drawing in which it is illustrated and-in which- Figure 1 is a view in side elevation of a shot gun of the type referred to. Fig. 2 is a partial view of the same on a larger scale,

partly in elevation and partly in longitudinal section, illustrating the application of the invention thereto.

The gun, whether riiie or shot gun, to which the invention is shown as applied may be of anyv usual .or suitable construction,

comprising a barrel a, a receiver or frame a stocke,- a magazine tube ci, a fore-end or grip-piece e arranged to slide on the magazine tube al, and a slide bar f througl'i which the movement of the grip-piece e is communicated to the breech mechanism. The gun is shown in Fig. 2 as limited to two shots, one cartridge g being shown in posi,- tion in the chamber (Z1 of the barrel and another cartridge g1 being shown in position in the rear end of the magazine tube d in readiness to be pushed out of the same by the spring follower or cartridge feeding spring and transferred by the breech mechanism to the chamber of the barrel. The spring follower is also shown as of usual construction, comprising a long coiled spring h. placed within the magazine tube (l, a cap 7L which is free to slide within the magazine tube and receives the end of the spring h, abutting against the forward end of the cartridge-g', and an abutment/i2 for the forward end of the spring h, such abut-ment serving both as a closure for the forward end of the magazine tube 7L and as a bracket by which the forward end of the magazine tube Z is fastened to the under side of the barrel, as by a screw 71.3. Within the magazine tube d and within the coils of the spring 7L, is placed a rod z' which supports the spring h and also forms a stop to limit the forward movement of the follower cap .71. Obviously this rod or transformer may be of any desired length, according to the number of cartridges which are to be inserted in the magazine tube. As shown, the rod is of such length as to permit only one cartridge to be inserted in the magazine tube so that, with one cartridge in the chamber of the barrel, the gun becomes a two-shot gun.

The device can be applied readily to existing guns without requiring modification in their structure and accomplishes its intended purpose without interfering in any manner with the proper operation of. the gun.

I claim as my invention 1. In a magazine gun, the combination of a barrel, a receiver, a magazine tube, a grippiece arranged t0 slide on the magazine tube, a slide bar, a closure at the` forward end of the magazine tube, a spring follower Within the magazine tube, and a removable sto independent of the said closure and the sai follower and arranged between the two magazine tube andthe cap of the follower to limittheforward movement of thecap and to support the spring'. f f

3. In a firearm, theV combination-with the tubular Amagazine and 'cap thereof, of a spring-actuated cartridge follower longitu# dinally movable in said magazine, anda rey .movable transformer located within the said magazine tube and having a bearing at the forward end against said cap. and adapted v at its rear end to limit the forward movement ofthe cartridge follower.

4. In' a firearm, the combination with the tubular magazine land cap thereof, of a cartridge followerl located in said magazine, a spring within said magazine and tending to i force the follower. rearward, and an independentlyl formed rod located within the 5 said spring and having a bearing at'the forward end against 'the magazine cap and adapted at its rear end to be engaged by the l said cartridge follower whereby fthe forward movement ,of the cartridge follower is po-sitively arrested. v

, 5. In a magazme gun, a tubular magazlne 1 closed atgone end, a cartridge feeding spring and follower therein, and a'removable stop Copies of this patent may be obtained for independent of the magazineand the follower and .arranged between th"follower yand the closed end of thomagazi-ne to limit o lthe number of cartridges that may be placed therein by standing'in the path thereof.

6. In a magazine gun, a tubular magazine closed at one end, a coiled cartridge feeding spring andfollower therein, and a removable stop independent of the magazine and the follower and arranged in the follower and the closed end of the magazine to limit thenumber of cartridges that may be placed therein by standing in the path thereof.

l7. In a magazine gun,'a tubular magazine, a coiled spring therein, a ,follower slidable in the magazine and movable by said spring, a removable plug at one end of the magazine, and a removable sto-p independent of the follower and the plug and arranged' in the magazinevbetween the follower and the lug to limit the range of movement of the ollower.

8. In a magazine gun, a tubular magazine, a coiled'spring therein, a follower slidable in the-magazine and movable by Isaid spring, a removable plug at one end of the magazine, and a removable stop independent of the follower and the plug and arranged in the magazine between the follower and the lug, said stop being'in the form'of a rod ocated within theooils of the spring.
