Substitute for application Serial No. 41,112, filed July 21, 1915. This application filed November 1, 1915. SerialNo. 58,987.

To all whom it may concern:

Be it known that I, GRANT HAMMOND, a

citizen ofthe United States, and a resident,

- in construction and that shall have means for engagement with the receiver to provide a rigid attachment.

One form of device embodying my invention and in the -use and construction of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawings, in which-- Figure 1 is a view inside elevation of the frame of a firearm embodying my invention.

Fig. 2 is a view of a portion of the rear end of a firearm embodying my invention.

with partsbroken away in central lengthwise section.

Flg. 3 is a view in cross section through my improved firearm on plane denoted by dotted line 33 in Fig. 2, looking rearwardly.

Fig. 4 is a sectional view, looking downwardly, of a portion of the rear end of my improved firearm out on a lane passing thro gh the is of the barre Fig. 5 is a detail side view of the trigger guard and magazine. 7

Fig. 6 is a bottom view of the same.

' Figs. 7 and 8 are face and edge views of the removable bottom of the magazine.

Fig. 9 is a horizontal section, on different planes, through a portion of the rear end of my improved firearm.

While my invention is not limited to any particular type of firearm, as it is readily adapted to a firearm that is discharged while supported against the shoulder of a erson, such a firearm is shown in the drawmgs herein for the purpose of illustrating the invention.

In the accompanying drawings the numeral 10 denotes the stock of the wooden frame part of a firearm embodying my 111- are recessed to receive the metallic parts comprising the frame of the gun, which, in the present instance, include a receiver 12 and a trigger plate 13 that is secured to the receiver as by means of screws 14, said receiver having a barrel 15 secured thereto in any suitable manner.

A magazine 16 comprising a part of the frame extends upwardly through the wooden frame and its chamber registers with an opening 17 through the bottom of the receiver, and said chamber and opening hre in vertical alinement with a discharge opening 18 in the top of the receiver. A breech bolt 19 is located in the receiver and it may be actuated in any suitable manner and the firing mechanism may be of any desired construction, a detailed description of such parts being, therefore, omitted, said mechanism, however, including a trigger 20 of any desired form and construction. The magazine 16 is formed integral with the trigger plate 13, projecting from the upper side thereof, and the bottom 21 of the magazine is held in place by a lip 22 on its front edge engaging a groove 23 in the trigger plate, a magazine locking bolt 24: retaining the parts thus engaged. This looking bolt is movably located in a well 25 in the rear wall of the magazine and in the bottom 21, a pin 26 permitting limited movement of the bolt within the well. A locking bolt operating prong 27 is formed on the end of the bolt and projects beyond a stop shoulder 28 formed at the mouth of the well 25, the length of this prong being uch that when an instrument is placed against it to push it inward, and in such movement the end ofthe instrument strikes the stop shoulder 28, the end of the main part of the bolt will have been moved inward beyond the upper surface of the bottom 21, and far enough to enable sliding movement of said bottom sufficiently to disengage the lip 22 from its groove. The bolt 24 is retained in its locking position as by a spring 29 which also presses against an ejector 30 in the opposite end of the well 25. This ejector has a flattened portion 31 adapted to pass into a slot 32 in the forward end of the breech bolt and back of a cartridge shell to eject the latter as the breech bolt moves backwardly.

In the preferred form of construction a recess 33 is formed in the bottom 21, extendcelver shall not ing preferably partially through it, a hole extending from the bottom of the recess to the opposite side of the bottom of the magazine, and through which hole the lower end of the bolt 24 projects, this hole, in fact, comprising. a part of the well 25. This recess is larger in diameter than said hole and also the locking bolt so that there is a space 34 between the wall of the recess and the prong 27, the bottom of the recess in the con struction shown comprising the shoulder 28. The invention, however, is not limited to a structure in which the recess extends only partially through the bottom. This enables an instrument slightly larger in diameter than the width of the space 34 to be inserted in the recess and pressed against the prong 27 to move the locking bolt inward to.release the bottom 21 and without interfering with "its sliding movement the groove 23. In order to rigidly connect the receiver and magazine the latter has a part extending into the receiver and in order that the rebe weakened by undue cuttingaway the rear end wall of the is extended at 35 above its side to disengage it from magazine parts, this extension being slightly narrower than the magazine to fit between the side walls 36 ofa recess 37 in the under side of the receiver and restin against the edges bounding said recess, as s own in Figs. 4 and 9 of the drawings, A rib 38 is formed at the back of the magazine on the outer surface thereof and extending in the direction of its depth, the upper end of this rib being locatedin a groove 39 at the end of. the opening 17. The upper edges of the side and end walls of the magazine rest closely against the under side of the receiver around the edges of the recess 37. The well 25 is located in the rib 38, the upper end of which is flush with the bottom wall of the breech bolt chamber 40 in the receiver.

While I have shown and described herein a satisfactory construction of parts embodying my ideas, this may be departed from to a greater or lesser degree and yet be within the spirit and intent of the invention.
