Claims.

This invention relates to magazines for firearms, and the said invention is of particular importance when associated with the usual pistol of the repeater type, and the said invention may 5 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 10 invention further includes novel means for carrying a plurality of chambers or magazines adjustable with relation to the hollow pistol grip, so that when the cartridges of one chamber are exhausted, the magazine may be expeditiously ad15 justed 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 20 lop and which has novel means for mounting a plurality of chambers for rotation, in order that the successive chambers may be manipulated, as stated, and the invention includes novel means for feeding or forcing the cartridges from the 25 chambers to the pistol grip.

It is a still further object of the invention to provide a device of the character indicated of comparatively large capacity, yet which is inconspicuous and inexpensive to manufacture and main30 ^tain.

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 35 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 40 views, and in which—

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 45 view of a fragment of the attachment taken on the line 2—2 of Fig. 1;

Figure 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. 55 1, omitting the pistol; and (Cl. 42—49)

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. g

In these drawings, the magazine has a plurality of columns 10 produced by an irregular enclosing wall forming chambers 11, in each of which cartridges 12 are superimposed above a follower 13, which is forced upwardly or toward the top of io the magazine by a spring 14 engaging the follower and a base plate 15 which closes the end of each chamber and one of which is secured in a suitable manner to each column 10. A circular apertured plate 1 δ is secured below the base plates 15 15 in any^ appropriate way, as by screws 17. A plate 18 at the upper end of the magazine has a hollow extension 19 forming a conduit which projects into tne hollow pistol grip 20, and cartridges which are forced therethrough are successively 20 delivered to the firing chamber of the pistol, which latter may be operated in any well known manner, but preferably automatically. The plate 18 has two apertures 21 and 22, the former of which registers with the conduit 19 and the latter of 25 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 14 which, as stated, acts on 30 the follower 13.

The plate 18 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 27 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 10 are fitted and the upper ends of these columns forming the chambers 11 are to register with the aperture 21 when the cartridges are to be delivered to the firearm through the extension 19 heretofore described 45 The bushing 25 is threaded in the upper end of the tube 27, and the said bushing has a flange 25' which engages the upper end of the tube and lies in a recess 25^a formed in the bottom of the plate 18. The magazine rotates with the 50 stud 24 whose head rotates on the shoulder of the opening 23 so that the tube, the hushing, 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 55 :o aperture 21 or with the charging aperture 22. A screw 28 threaded in the lower end of the tube 27 aids in retaining the magazine and tube assembled. _ ,

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 19 and, in order to provide a readily manipulatable detent or latch, a leaf spring 31 is secured on the upper surface of the plate 18 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 may 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 18 and limits its upward movement while being withdrawn from one of the recesses 29.

As indicated, the aperture 22 is for the purpose of delivering cartridges to the magazine and it is provided with a sliding closure 34 which operates in suitable guides 35 at the edges of the opening, and the said closure may be 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 iO are preferably formed of sheet metal, they fit into the radial openings of the plate 26 and may be secured therein by welding or the like. A detail of construction of each follower 13 shows that it has lugs or extensions 36 which travel in grooves or channels 37 formed in the columns JO, as by bulging the said columns as shown in Fig. 5. The channels, । however terminate just short of the upper ends of the columns and the unremoved portions 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 dis’ charged from the chamber 11.

The upper end of the extension 19 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 19 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 41, 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 firing chamber.
