This invention relates to magazines for rearms, and the said invention is of particular importance when associated with the usual pistol of the repeater type, and the said invention may be made to operate in conjunction with cartridges of different gages.

it is an object of this invention to provide a magazine for cartridges which may be applied to or removed from a hollow pistol grip; and the invention further includes novel means for carrying a plurality of chambers or magazines adjustabie with relation to the hollow pistol grip, so that when the cartridges of one chamber are exhausted, the magazine may be expeditiously adjusted to position a succeeding chamber or magazine section in operative relation to the hollow pistol grip.

It is furthermore an object of this invention to provide a device which is applicable to the pistol grip and which has novel means for mounting a plurality of chambers for rotation, in order that ihe successive chambers may be manipulated, as ed, and the invention includes novel means for feeding or forcing the cartridges from the chambers to the pistol grip.

is a still further object of the invention to provide a device of the character indicated of comparatively large capacity, yet which is inconspicnous and inexpensive to manufacture and maintain.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which- I Figure 1 illustrates a view in elevation of a pistol partly in section, with a device embodying the invention shown in section applied thereto;

Figure 2 illustrates an enlarged detail sectional view of a fragment of the attachment taken on the line 2 2 of Fig. 1;

Fig-ure 3 illustrates a plan view of the top plate of the attachment taken on the plane of the line 3-3 of Fig. 1;

Figure 4 illustrates a sectional view of the device on the line 4 4 of Fig. 2;

Figure 5 illustrates a sectional view on the line 5--5 of Fig. 2;

Figure 6 illustrates a bottom plan View of Fig. l, omitting the pistol; and

Figure 7 illustrates a sectional View through one of the columns showing the detail for arresting the follower at the upper end thereof.

Fig. 8 is an isometric view of the upper end of the magazine extension.

In these drawings, the magazine has a plurality of columns i0 produced by an irregular enclosing wall forming chambers Il, in each of which cartridges i2 are superimposed above a follower I3, which is forced upwardly or toward the top of 10 the magazine by a spring I4 engaging the follower and a base plate I5 which closes the end of each chamber and one of which is secured in a suitable Vmanner to each column I0. A circular apertured plate it is secured below the base plates I5 15 in any appropriate way, as by screws Il. A plate i8 at the upper end of the magazine has a hollow extension i9 forming a conduit which projects into the hollow pistol grip 2G, and cartridges which are forced therethrough are successively delivered to the ring chamber of the pistol, which latter may be operated in any well known manner, but preferably automatically. The plate I8 has two apertures 2l and 22, the former of which registers with the conduit I9 and the latter of V25 which is provided for the purpose of charging the magazine, it being shown by dotted lines in Fig. 1 that the cartridges are suspended above the opening 22 and forced inwardly against the action of the spring I4 which, as stated, acts on.30 the follower I 3.

The plate I8 has a shouldered opening 23 in which an appropriate stud of screw 24 is rotatably supported and the said screw is threaded in a bushing 25 in the transverse center of the 35 magazine. A plate 26, to be hereinafter more particularly described, is fitted on the upper end of a tube 2l which is stationed in the center of the magazine and extends from one end to the other thereof. The plate 26 has radial openings `40 into which the columns I D are fitted and the upper ends of these columns forming the chambers II are to register with the aperture 2| when the cartridges are to be delivered to the firearm through the extension I 9 heretofore described. 45 The bushing 25 is threaded in the upper end of the tube 21, and the said bushing has a flange 25 which engages the upper end of the tube and lies in a recess 25a formed in the bottom of the plate I 8. The magazine rotates with the stud 24 whose head rotates on the shoulder of the opening 23 so that the tube, the bushing, the plate 26 and the magazine assembly rotate with the said screw to bring the several chambers of the magazine into successive registry with the y sembled.

As has been stated, the plate 26 has a plurality of peripheral recesses 29 so located with relation to the cartridge chambers as to receive a detent when a chamber is in registry or alinement with the conduit I9 and, in order to provide a readily manipulatable detent or latch, a leaf spring 3| is secured on the upper surface of the plate I8 by a fastening 32 .such as a screw, and this spring has on its outer end a detent or lug 33 which enters an appropriate recess 29 of the plate 26 and thus the plate 26 and the attached magazine are held at different positions of adjustment by the latch. The latch is so located that it ymay be expeditiously manipulated to release the magazine to permit it to turn to bring the successive cartridge charges into position for feeding the pistol. The lug 33 has a pin 33 or the like which engages the plate' i8 and limitsr its upward movement while being withdrawn from one of the recesses 29.

yAs indicated, the aperture 22 is for the purpose of delivering cartridges to the magazineand it is provided with a sliding closure 34 which operates in suitable guides 35 at the edges of the opening, and ther said closure maybe moved to the dotted line position shown in Fig. 3 to unguard the opening and to the full line position of said figure to close the opening.

As the columns I0 are preferably formed of sheet metal, they fit into the radial openings of the plate 26r and may be secured rtherein by welding or the like. A detail of construction of each follower I3 shows that it has lugs or extensions 36 which travel in grooves or channels 3l formed in the columns I0, as by bulging the said columns as shown in Fig. 5. 'I'he channels, however, terminate just short of the upper ends of the columns and the unremoved portionsy of the columns at the upper ends form abutments which are engaged by the lugs and thus the upward movement of the follower is arrested at a point where the last cartridge has been discharged from the chamber II.

The upper end of the extension I9 through which cartridges are delivered to the firearm is positioned, as in the manner of the usual magazine, adjacent the firing chamber of the gun. Said upper end of the extension I9 has portions of its walls slidably inturned as at 38, Whereas the other portion 39 remains of the same dimensions as the portions of the extension therebelow. This results in a restricted opening 40, as compared with the opening 4I, and the restricted opening retards the movement of the cartridge slightly so that it tilts the projectile of the cartridge above the shell to better present the projectile to the chamber of the firearm and thereby facilitates the delivery of .the projectile to the said ring chamber.

I claim:

l. In a magazine for rearms, a plate having receiving and discharge openings for charges to be stored andfdelivered to a rearm, means for delivering charges from the opening of the plate to the firearm, the said plate having an approximately centrally disposed opening with a shoulder inthe said opening, a shouldered rscrew hav-r ing its shoulder resting on the shoulder of the opening and projecting inwardly therefrom, a bushing threaded on the inner end of the screw, a tube rotatable with the bushing, a plate below the first mentioned plate rotatable withy the bushing, a magazine comprising a plurality of radially arranged chambers having its upper end anchored in the second mentioned plate, a bottom plate for each chamber of the magazine, a retaining plate thereunder, a screw threaded in the 'lower end of the tube and bearing against the last mentioned plate aiding in holding the parts assembled, a follower in each of the said chambers, a spring in each chamber urging the said follower toward the aforesaid plates, whereby charges interposed between the said followers and the second mentioned plate are forced upwardly and when a chamber is in alinement with the tube of the rst mentioned plate force the rsaid charges from the chamber.
