MILITARY SHOULDER-ARM.

Specification of Letters Patent.

Patented Jan. 25, 1916.

Application filed November 5, 1915. Serial No. 59,801.

To all whom it may concern:

Be it known that I, THOMAS C. J OHNsoN, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Military Shoulder-Arms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon. to be a full. clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure l a view in right hand side elevation of the middle portion of a military shoulder-arm constructed in accordance with my invention. Fig. 2 a reverse plan view thereof. Fig. 3 a view thereof partly in right hand side elevation and partly in rertical longitudinal section. Fig. 4 a detached broken side view of the forward end of the tang of the box-magazine of the gun. Fin; 5 a detached view in rear elevation of the foreetoc c. Fin. 6 a detached View in front elevation of the butt-stock.

My invention relates to an improvement in military shoulder-arms. the object being" to provide simple and reliable means for holding the forestoclr against longitudinal forward d splacementwithout imposing any strain upon the barrel of the arm.

With these ends in View. my invention con ists in a military shoulder-arm having; certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, the forestock 2 is formed near its rear end with a vertical locking-recess 3 entering it from its lower face for the reception of a lockin, z-lu 4 upstanding from a locking-arm 5 forming an integral, horizontal extension of the forward tang 6 of the box'magrazine 7, the lower face of the fore'stock being formed with a longitudinal clearance recess or groove 8 for the reception of the said locking-arm 5 and the said recess 8 intersecting at its forward end the locking-recess 3. When the lug 4: is crowded into the recess 3. the forestock 2 is securely held against longitudinal forward displacement without the imposition of any strain upon the gun-barrel 9. As shown, and by preference, the rear face of the lug i is slightly tapered as 'atlO to co-act with the correspondingly tapered rear wall of the recess 3 so as to insure the drawing of the forestock solidly into place in assembling the gun. Also, as shown, the forward wall of the recess 3 and the forward face of the lug 4 are rounded, though this is not necessary.

As shown. the forestock 2 is formed at its rear end with a tenon l2 entering a shallow recess 13 in the forward face of the lower portion of a receiverextension 14 screwed upon the forward end of the receiver 15 which is provided wi h a threaded opening 16 for the reception of the threaded shank 17 of the gun-barrel 9. The butt-stock 18 which may he of any approved construction, is formed at its forward end. as shown, wi h a tenon 19 entering a shallow recess 20 in the rear face of the recei er-extension 14. A screw 21 passing upward through the tang 6 into a threaded boss 22 upon the rear face of the. receiver-extension 14 secures the said tang" in place. As shown the tanq' 6 is formed upon i s upper face with a circular locking boss 23 entering a corresponding recess 24: in the lower face of the receivenextens on 14. wherehv the tang is i self held again t endwise dis lacement and the screw 21 relie ed of strain. So far as my pre ent invention is conce ned the receivenextension might be made integral with the receiver.

The term receiver in the claims is to be understood as covering the receiver whether its extension is integral or otherwise except in those claims in which the receiver-extension is specifically mentioned.

I claim 1. In a military shoulder-arm. the combination with the receiver thereof. of a forestock formed in its lower face with a lockinn-recess. and a tang connected to the receiver and provided with a forward extension entering the said recess for holding the said 'forestock against longitudinal forward displacement.

2. In a military shoulder-arm. the combination with the receiver thereof. of a receiver-extension, a forestock provided in its lower face with a locking-recess, and a tang secured to the said receiver-extension and formed with an integral locking-arm provided at its forward end with an upstanding locking-lug entering" the recess in the forestock for holding the same against forward longitudinal displacement.

3. In a military shoulder-arm, the combination with the receiver thereof, of a receiver-extension, a forestock provided in its lower face with a locking-recess, and atang secured to the said receiver-extension, provided with a forwardly extending lockingarm entering the said recess in the fore stock, and also provided with a locking-boss entering the said receiver-extension.

4. In a military shoulder-arm, the combr nation with the receiver thereof, of a forestock formed in its lower face with. a locking-recess, and a box-magazine provided with a forwardly extending tang, having an integral locking-arm entering the said recess for holding the said forestock against longitudinal forward displacement.
