MAGAZINE FOR FIREARMS.

Patented Jan. 7, 1919.

Original application filed April 20, 1915, Serial No. 22,590. Divided and this application filed July 21, 1915.

Serial No. 41,110. i

To all whom it may concern Be it known that I, GRANT HAMMO ND, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Magazine for Firearms, of which the following is a specification.

My invention relates to devices for containing the cartridges in a firearm, prior to their being moved into the barrel, and an object of my invention, among others, is to provide a magazine that shall be particularly effective in operation and one that may be readily operated for purposes required.

One construction of magazine embodying my invention and in making and use 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 in side elevation of a portion of a firearm embodying my invenposed of wood and shaped and formed to receive the metallic parts in a manner well known. A barrel 13 is secured to the frame or receiver 14 in any suitable manner. A breech-bolt 15 is rotatably mounted in a breech-bolt chamber 16 in the frame or receiver in any suitable manner and is provided with locking and releasing lugs 17 arranged to pass along lengthwise grooves 48 formed in the receiver and into an annular locking groove 18 to lock the breech-bolt in its closed position, in which it closes a discharge opening 19 at the top of the receiver. A firing bolt having a firing bolt head 20 is located in the breech-bolt, and an actuating lever handle 21 is employed for operating the breech-bolt. All of the parts hereinbefore described, except in their general relation, constitute no part of the present invention, but being embodied in the invention of the application hereinbefore set forth tion with parts broken away to show the construction of the magazine.

Fig. 2 is a bottom view of a portion of the firearm shown in Fig. 1.

Fig. 3 is a detail view illustrating the construction and operation of the magazine sup porting members.

Fig. 4 is a detail view, scale enlarged, in cross section through the device at about the longitudinal center of the magazine.

Fig. 5 is a similar view on plane denoted by dotted line 55 of Fig. 6. n

Fig. 6 is a detail view showing the construction and operation of the magazine shifting rod.

Fig. 7 is a detail view, scale enlarged, illustrating the construction and operation of the retaining post in its socket in the receiver.

My invention is not necessarily confined to any special type of firearm but as it readily adapts itself for use in connection with that class that are supported on the person and commonly against the shoulder when fired I have chosen such type for the purpose of illustrating my invention herein, this application being a division of my co-pending application filed April 20, 1915, of Serial Number 22,590.

In the accompanying drawings the numeral 10 indicates the stock of a firearm that includes the forestock comprising a top piece 11 and a bottom piece 12, preferably comand of which this is a division, further description is omitted herein.

A trigger guard plate support 22 is attached to a post 23 secured to the receiver in any suitable manner, and a trigger guard plate 24: is pivotally mounted between ears 25 formed on said support. A trigger guard sleeve 26 fits a screw threaded opening in the rear end of the trigger guard plate, and is provided on its inner end with slots as a means of adjusting its position. A trigger guard post 27, rigidly secured to one branch of the trigger guard 28, has a thread at its base to fit the threaded inner wall of said sleeve and the opposite end of the post is flattened and its edges are threaded to fit a partially threaded hole in the rear end of the frame or receiver 14. The opposite end or branch of the trigger guard has a stud 29 to fit a hole in the trigger guard plate, the guard being sufiiciently resilient to enable it to be sprung so that the stud may enter the hole in the plate and be held therein by the spring action of the guard, the sleeve 26 being adjustable for the purpose of regulating this spring action. By springing the guard and disengaging the stud from the hole, and turning the guard to an angle of about ninety degrees from its regular position, the threads on the end of the-post 27 may be disengaged from the threads in the hole in the receiver, and the trigger guard plate is thus unlocked and may be swung downwardly,

I and a reverse movement of the parts just above describedwill lock the trigger guard plate in itsclosed position. i

A trigger supporting frame 80 is-moun ted on the plate 24, projecting from the inner face thereof,- and a trigger 31 is-pivota'lly" mounted between the, side parts of this frame, said trigger having a notch in *its upper end to receive a lug 32 projecting from a sear 33 that is also pivotally mounted between the side parts of said frame.

= breech-boltim front end will engageaa car This sear has projections hat to -,operate connection with he breech-(homes described n, my coepending application hereinhefore referred to and ofwhich application-this is a. division.

A magazine is pivotal'ly ,rnountedupon a pin 36 that p-ivotally secures the trigger guard plate 2%} to the support 222- The upper part of an end- :Wall of this magazine hasanangularly shaped slot 37 to receive an eccentrically mounted -pr0j-ection.38 on the end of amagazine shifting rodfit) rotatably mountedin the frame and having. a magazrne shifting lever .40 secured atitsmllter end. Notches 4:1 in the-shifting lever 40' receive the rounded end .of' a 1 spring pressed shifting lever holder 42, located insa recessin the frame andqseated upon asp ring. that resiliently holds the pin in engagement with" the notches the lever but whichwill yield under .sufficient force to ,permit manna] movement of the lever. When this lever isin the position shown in Fig. .4: the magazine is fully seated within its ohamber'so that at each forward movement of the tridge and push .it ,into therchamberuwit-hinthe barrel. When; the .lever is turned to the position shown by dotted lines Taxi-n Fig.

4 .the magazine will be loweredto-,such posi tion shown'by dottedli-nes in Fig. h) -tha t a forward movement of the'breech-b ll not push a cartridge ,intofthe magazine, but the loading will then be (10119 by hand, and when :the leveris .in' the position-shown dotted. line in Fig, 5 the-magazine Willob'e released so that it may be swung down-- wardly on its. pivot. This may 'hedone when'the breech-bolt has been-removed from theframe.
