MAGAZINE FOR SMALL-ARMS.

.; Application filed August 2,

Be it known that I, JnNs Lonny-photographer,-cit'izeniof Norway residing at Farsund, Norway, have invented certain new and useful: Improvements in Magazines for Small-Arms, of :which the following is a specification.

The. present i invention relates to improvements magazines; for rifles and Y has for its object a magazine which is capableof carrying a a greater number of cartridges 'thanugun magazines. :Eormerly -known. The present construction is especlally adapted for automatic 1 small-arms.

The capacity. for i holding great number of cartridges is obtained by giving the magazineva escrow-shaped form, and the-cartridges lie alongsidethe body of the screw and between the threads thereof.

An embodiment. of the inventioniis shown in the accompanying drawing, tin which Figures 1 and2 show a side and top view respectively of agun equippedwith the side magazine. I

Fig.= 3 shows'theinagazine itself'wlth the "inner screw shapedpart drawnout ipartly.

F-igs. tand fi showa top and -end view respectively of details of the cartridge-feeding device.

.Figs. 6 and? show, schematically, two forms of construction employed in :feeding the cartridges forward "and for introducing the cartridges into the barrelof thegun.

In the construction shown, the magazine is connected to an automatic: gun of a-known type; in which the-powder gases generated during firing are used tooperate a piston which-is connected to thebreech-block for opening the same closing of the breechblock a being carried out Joy-means of spring pressure.

Between these two cylinders 15. and

18 a spiral passageway is formed by the thread 17-, which corresponds with 1the diameter and the length of the cartridges. When the magazine is filled, the cartridges are arrangedwiththeir sides toward the in ner cylinder 18 and they contact at the front, and rear, with the thread -17. By forming the magazine in this manner a greater number of cartridges can be stored than in any magazine formerly known.

The cartridgesare driven toward the-gun barrel by means of the following arrangement:

The wall of the innercylinder 18- is provided throughout its entire length with a; spiral. slot; 19, .which is located intermediate thescrew-threads l7 and has the same fpitch as the screw threads. In this slot a slide-20- travels, whose foot 21 (see Eig. 6) slides in guides 22, 23, made of. steel. The guides are situated in the 'inner cylinder 18- and consist of two arms .-22- and 28 the'first of which 22 is slotted throughout its entire lengthiby asslot -24.- in which the tongue -25 -(seeFig. 3) of the slide 20 travels. Throughout the entire length of the other arm .23-. aigroove extends for guidingthe ,foot 26- of the slide (see Fig.6). I

The arms +22, 23- are of the same length as themagazine and carry at their front end a :cover -27.- for the front end of the magazine. The'front face of the cover is providedwith. a gear 28- with which a smaller gear 29 meshes. This gear 29- is-mounted on a fixed shaft 30 whiclrextends into -aspring case 31 located on the side of the gun (see Figs. 1 andw2). Thiscase contains a strong spiral spring (not shown) which may be wound up by means of an outer crank'handle -32.

Afterfther-spring (hereinafter calledthe -magazine springhhas Lbeen wound up by turning' t-he crank (and the gear 29) indirection of the arrows in Figs. 1 andq3 thearms 22and 23fwill berotated inthe direction-of the hands of a watch this causes the cartridges to; be 'moved forward toward the gun barrel. Some stopping device for the gear which be managed from the outside of the gun may be employed if desired. Such a device is shown in Fig. 5 in which a pawl -32 is used to stop the gear :2%,). When the magazine is opened, that is during the firing, the cartridge series are fixed by the leading cartridge which strikes against the closed breech block or against a' knotin the lock case upon which the breech block is acting. I i In Fig. 6, I have shown one form of the device for feeding the cartridges forward to the lock case. As the car-tridgesreach the lock case, they travel upward on an inclined guide -3l and are thereby lifted through an opening 35 (see Fig. 3) into the lock case, where they are caught by the breech block and led into the cartridge chamber in the usual manner.

In the construction shown in Fig. 7 the slide -20 is formedas'a head lying loose in the cartridge chamber. In this head a spr ng pressed flap -36 is arranged. WlVlllCll extends to some degree into the slot 19 of the inner magazine sleeve +18 and against which the arm 22- of the interior guides act during the forward movement of the cartridges. In this con- 40 st'ruction, the high friction between the slide 20 and the guides 22, 28 is avoided and more force upon the cartridges is obtained. When the spiral spring in the casing 3l is wound up, the spring ressed fia 36 durin the ti iefn p p g g L H g "3, means extendingthroughthefcore and of the spiral spring at each turn will travel over the arms '22, 23. The slide head 20 in this incident is moved rearwardly with the cartridges during the filling of the magazine and acts as aguide for the cartridges, preventing the same from. sticking fast or turning across the magazine. A slide of this construction is preferred to the form shown in Figs. 3, 4 and 6. After the magazine has been filled, the spiral spring is wound up by means of the crank handle -32. I

The reloading of the magazine may be accomplished in different, ways. It may be accomplished by introducing the cartridges through the magazine opening 37- (see Figs. 1 and 2) after the slide 20 has been led back to" its rear position. The magazine can bemade removable if desired guide is turned.

and may be replaced by another filled magazine.

The magazine can be adapted to different types of guns and adjusted for a greater or lesser number ofjcartridge by altering the diameter and length of the cylinders.

If the spiral spring in the case 31- should not be capable of bringing forward the cartridges in a large magazine, an auxiliary spring may be placed in the rear of the magaz ne to asslst 1n the operatlon. v

In the above specificatlon the magazine 1s described as'ofacylindrical form, but the form may of course be changed without departing from the spirit of the invention.
