Application filed Juno 4,1884. -(Model.)

To all whom it may concern,;

Be it known that l/Louis P. Diss, of Ilion, • in the county of Herkimer and State of New

York, have invented certain new and ijseful 5 Improvements in Magazines for-Fire-Arms, of which the following is a specification.

. This invention relates to detachable magazines for firearms; and jthe invention consists in the arrangement of a single curved spring io for feeding the cartridges from the magazine into the shoe of the gun, and in a novel arrangement of the detent for retaining the cartridges in the magazine, and in certain combinations of-deyices, as hereinafter more fully 15 set forth.

Figure 1 is a perspective view; Fig. 2, a longitudinal vertical section; Fig. 3, a transverse section on the line χχοΐ Fig. 2. Fig., 4 is a longitudinal vertical section of a portion 20 of the magazine.

In constructing my improved magazine I make the box or body A as usual, and preferably with internal vertical ribs or guides, a and r, as shown, with a follower, C, having 25 ears or projections to operate in connection with said guides, as described in a previous application pending herewith. It has also the usual lips, d, at the rear end, to hold the heads of the cartridges from rising beyond a certain 30 point, and it may be made with its bottom open or closed, as may be preferred; but if open itshould have an inturned flange, o, along each side of the bottom, as shown in'Fig. 4.

Instead of the zigzag spring heretofore gen35 erally used, I use a single flat spring, curved, as shown in Fig. 4. This spring is secured to the end wall of the box, preferably the front wall, in any suitable manner, by one of its ends, while its other end is left free to bear 40 against the under side of the follower, as shown in Figs. 2 and 4. In this case I have • shown the end of the spring as being fastened to the box by inserting it,through a transverse slit cut in the end wall near its top, and bend45 ing the end down and pressing it snugly down against the outside, as shown in Fig. 2. It is so secured in this case because of the fact that the detent h has its end c passing through said slit, and the spring cannot pass up in front of said end c of the detent, as it would interfere 50 with its operation. It is, however, obvious that it might be secured by a rivet to the wall of the box below the slit, or in those cases where the detent is not used, or is located at some other point. The end of the spring 55 might be hooked over thejop edge of the box, and be secured there in the same manner. The free end of the spring D is bent or curved, as shown, at its free end to form a rounded surface at the point of contact with the follower 60 C when pressed down, as shown in Fig. 2, so as to permit of a free action and prevent the end of the spring from catching on the follower, as it might otherwise do. . The spring C is so curved as to raise the follower to the 65 extreme top or mouth of the box, and is made to bear against the follower nearest its front end, as shown in Figs. 2 and 4, whereby it insures the keepjng of the front end of the cartridges elevated, as is necessary in this style 70 of magazines. This style of spring may be used in all magazines of this class, but is preferably used in those which have the guides or vertical ribs r and a on their sides and have the follower C provided with ears or projections 75 operating in connection with said ribs, as described in my previous application, as by those means the follower is held in position, and is prevented from tipping up and becoming displaced. 80

To retain the cartridges in the box when detached from the arm, I make use of a sliding spring-detent originally invented by Roswell F. Cook, but apply it differently. This detent is shown in each of the figures, and it 85 consists of a flat strip of metal, preferably of steel oc.equivalent spring metal, as indicated by b in the several figures. Its upper end, <·, is bent so as to incline inward, as shown clearly in Figs. 2 and 4, and it has a shoulder or pro- 90 jection, 1,. formed on its body at the proper point to be brought in contact with the stock or frame of the arm, or with some projection thereon, for the purpose of automatically moving it as the box is shoved into place when 95 applied to the gun, and thereby release the Cartridges. The upper inclined end, c, of this detent b is inserted through a transverse slot

303,992 cut in the front wall of the box near its top, as shown in Figs. 1 and 2, while its lower end is inserted through a.loop, e, which is formed by cutting a couple of transverse slits in the

-5 wall of the box and stamping the metal between the slits outward, as shown more clearly in Fig. 1. When the detent is pushed downward, its point c is drawn out of the slot, and its extreme upper end or point will rest against the outer face of the box, as shown in Fig. 4, when the cartridges can be inserted by pushing their heads in under the lips d at the rear end and holding their front ends down until the box is filled, and then by sliding the de15 tent δ upward its inclined end c will pass through the slot and engage over the point of the uppermost cartridge, as shown in Fig. 2, thereby fastening the cartridges securely in the box. In order to prevent the inclined end of the detent from being straightened out by pressure or accidentally in any way, I fill in the angle or front corner of the box above the slot through which the inclined portion of the detent slides by a solid beveled piece, 0, as shown in Figs. 2 and 4. This not only forms a support for the inclined end c of the detent, but it also serves as a guide for the end of the detent as it is shoved in. Instead of making this piece or part 0 to extend across the entire

-front wall, it may be made in the form of a small shoulder or ledge located in each corner and answer the same purpose, these shoulders of course being similarly inclined. By thus providing a support and guide for the inclined end of the detent, I am also enabled to make the latter thinner and more elastic, and this enables it to be more easily moved and to operate in a very perfect and satisfactory manner. By locating the detent at the front end of the box, instead of at the side, I avoid the necessity of cutting away the stock and metal of the frame as much as would otherwise be necessary, and thus to that extent avoid weakening the gun at that point; and this is an im45 portant consideration in a gun of that class 01· style with which these detachable magazines are to be used, because of the extent to which they have to be cut aw ay to receive the magazine. Besides, it makes a most effectual lock for retaining the cartridges, as it engages with 50 their extreme front end, while t.ieir rear end is held firmly by the rigid lips d at the rear end of the box.

Amagazine constructed,as herein described, with a>single spring, and with a follower pro- 55 vided with the means for guiding and controlling its movements, and with the elastic detent guided and supported as described, operates in most satisfactory manner.
