THOMAS C. JOHNSON, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO WINCHESTER REPEATING ARMS CO., OF NEW HAVEN,' CONNECTICUT, A CORPORATION.

MILITARY SHOULDER-ARM.

Speccaton of Letters Patent.

Application filed November 1, 1915. Serial No. 58,969.

To all whom t may concern:

Be it known that I, THOMAS C. JOHNSON, 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 lVIilitary 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 bea full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Figure 1 a broken 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 in horizontal section on the line a-b of Fig. 1, looking downward. Fig. 4 a detached view in rear elevation of the forestock. Fig. 5 a broken plan view thereof. Fig. 6 a detached view in rear elevation of the receiver-extension. Fig. 7 a detached view in rear elevation of the tie-piece. Fig. 8 a plan view thereof.

My invention relates to an improvement in military shoulder-arms, the object being to provide simple and effective means for holding the forestock against forward dislplacement without imposing any strain whatever upon the barrel.

l/Vith these ends in view, my invention consists in a military shoulder-arm having certain details of construction as will be lhereinafter 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 transversely arranged, vertical recess or chamber 3 the upper end of which intersects the longitudinal, semi-circular groove 4 formed in the upper face of the forestock to adapt the same to t around the lower face of the barrel 5 from which the walls of the said groove are very slightly cleared. The recess 3 is designed for the reception of a metal tie-piece or anchor 6 conforming in shape to the shape of the recess 3, having its upper end cut away as at 7 for the clearance of the barrel and furnished with two threaded holes 8 extending from front to rear for the reception of the threaded forward ends of two tie-bolts 9 arranged in a horizontal plane and located for the moet part in bolt holes .10 entering the .rear

face of the forestook and extending forward to intersect the rear wall of the recess 3. At their rear ends the tie-bolts 9 are provided with slotted heads 11 and are passed from rear to front through bolt-holes 12 counterbored as at-13 for thereception of the boltheads 1l as clearly shown in Fig. 3, and

formed in the receiver-extension 14 the upper portion of which is provided with a large threaded opening l5 adapting it to be screwed upon the projecting forward end of the receiver 16 which is formed with a threaded opening 17 for the reception of the threaded shank 18 of the barrel 5. The forward face of the receiver-extension is formed with a shallow recess 19 for the reception of a tenon 20 at the extreme rear end of the forestock 2, while the rear face of the said extension 14 is formed with a shallow recess 21 for the reception of a tenon 22 upon the extreme forward end of the buttstock 28, with which the present invention is not concerned, and which may be secured in place in any convenient manner. As shown, the rear face of the receiver-extension is formed with a semi-circular recess 23 for the reception of the forward end of the forward tang 24 of the box-magazine 25, and with a threaded boss 26 receiving a screw 27 b means of which the forward end of the said tang is secured to the receiver-extension.

It will be understood from the foregoing that the tie-bolts 9 acting through the tiepiece or anchor 6, hold the forestook 2 solidly against the forward face of the receiver-extension 14 without imposing any strain of any description upon the barrel 5 which is thus left entirely free except as it is mounted in the receiver. Inasmuch as the receiver-extension 14 is virtually a part of the receiver itself, the forestock is therefore solidly attached, to all intents and purposes, to the receiver. So far as my present invention is concerned, the receiver-extension 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, a tie-piece located therein, and one or more tie-bolts connecting the saidk receiver and tie-piece for holding the forestock solidly against forward longitudinal displacement.

2. In a military shoulder arm, the combi- 5 nation With the receiver thereof, of a forestock, a tie-piece located therein, and two tie-bolts located in a horizontal plane and connecting the said receiver and tie-piece for holding the forestock solidly against forward longitudinal displacement.

3. In a military Ashoulder arm, the combination With the receiver thereof, 0f a forestock formed. in its upper face With a vertical, transversely *arranged* recess, a tiepiece located therein, and one or more tiebolts connecting the receiver and tie-piece for solidly holding the forestock against for- Wardv longitudinal displacement. y

4. In a military shoulder arm, the combination with the receiver thereof, of a receiver-extension attached thereto, a forestock formed with a recess, a tie-piece located in 'the said recess, and one or more tiebolts connecting the said receiver-extension and tie-piece for holding the forestock solidly against the receiver-extension and against forward longitudinal displacement.
