PATENT OFFICE.

In the case of the subject of my patent no. 4-7777 forming quick loading device for rear loading rifles of all systems, the magazine top wall is supported by a leaf spring, which at. Filling the magazine must be bent to the side.

The purpose of the innovation for rapid charging devices of the type in question is to use one of spring force to create an independent shutter for the upper side of the magazine, which allows an insertion whole cartridge container and individual cartridges in the magazine.

The essence of the invention is characterized by the upper magazine opening Closing pendulum flap, the pivot of which is eccentric at the upper edge of the magazine to the print direction of the cartridges are stored.

An eccentric that is rotatably attached to the flap and is supported on the magazine outer wall The flap serves as a support against the buoyancy of the cartridges and can be rotated in such a way that that the flap is kept in the lowered position, so that the cartridges can be passed into the lateral magazine opening is prevented.

In the accompanying drawings there is a rapid charging device embodied in accordance with the invention shown in connection with a rifle with cylinder closure, namely shows;

Fig. Ι a perspective view of the rifle with empty magazine,

Fig. 2 is an analogous view of the lock housing without magazine, with that in the housing attached opening for the passage of the cartridges,

3 is a view of the cartridge passage opening of the locking case on a larger scale;

4 and 5 are cross-sections ^along the lines xx and χ Ύ -χ ^ι in Fig. 3;

Fig. 6 shows the magazine in elevation;

7 is a section of the filled, function-ready magazine,

Fig. 8 the same blocked;

9 illustrates the insertion of a full cartridge container,

10 shows the pulling out of the same after the magazine has been filled;

11 and 12 show a rear end view the magazine when the magazine flap is ready for function and in the locked position;

Figures 13 and 14 illustrate a full one and an empty cartridge container;

Fig. 15 shows a top view of the magazine with. the lock housing with the lock open ;

Figure 16 is a top view of the magazine with the cartridge case inserted (the latter is shown in horizontal section);

Fig. 17 shows a cross section through the Lock case, after the magazine has been removed, with the cartridge inlet opening closed.

The cartridge container A belonging to the fast loading device and serving as a magazine has the known shape shown in FIGS. 1 and 6, and the cartridges are pressed by a stepped spring a, FIG. 6, against the flap A ^{1 closing the upper magazine opening.} Sliding along the lower rising surface of the parts of this flap A ¹ protruding in the present case as arms a ¹ ,

the cartridges reach the opening b on the side of the magazine itself, Fig. 12, or in the lock housing B, Fig. ι, 2 and 3, where they are grasped by the lock piston B ¹ , Fig. 15, and pushed into the hold.

In order to be able to fill the magazine with cartridges, the flap A ¹ can be rotated in axle journals a ² , which are mounted on the upper edge of the magazine A eccentrically to the vertical pressure direction of the cartridges. The magazine can be filled in packets or by means of individual cartridges. Packet-wise filling takes place with the aid of the cartridge packet container shown in FIGS. 13 and 14, which for this purpose is placed on the flap A ¹ and pressed vertically downwards. The flap, which moves outward around its eccentrically mounted pivot pin α ² , swings back as soon as the container C is completely pushed in, due to its own weight distribution over the uppermost cartridge, Fig. 10, closing the magazine opening, and prevents the Cartridges exit in a vertical direction. The shape of the flap is chosen so that the inserted packaging container C can be pulled empty from the magazine (see FIGS. 10 and 16).

An eccentric α ⁴ provided with a handle a ^{s is} rotatably attached to the flap A ¹ , which is supported on the magazine outer wall and serves both to lock the magazine, ie to bring the flap A ¹ into such a position and to maintain it in the same , in which a passage of the cartridges from the magazine into the lateral magazine opening b is impossible, as well as to fix the flap in that position in which the exit of the cartridges from the magazine takes place.

In Fig. 11 the position of the eccentric is shown in which the cartridges are fed through the curved lower surface of the flap A ^{1 of} the outlet opening b , while in Fig. 12 that position of the eccentric Λ ^{4 is} shown in which the flap A ¹ is pushed down so that the cartridges are retained in the magazine.

An approach α ⁵ , which is supported on the left bearing of one of the pivot ^{pins α 2 of} the flap A ¹ , prevents the flap from moving beyond the necessary extent outwards when the magazine is being filled.

When the magazine is removed, the opening b on the housing can be closed by a cover plate λ ⁶ , FIG. 7. The magazine A can be attached to the bolt housing in the usual way.

In the accompanying drawings are the parts of the valve on the lower surface of which the Cartridges slide when exiting the magazine than into the upper opening of the magazine protruding arms shown. Of course, several of these can be installed on the flap Arms may be present, or it may be the same as one over the entire upper magazine opening Reaching cover can be executed.

Claims (2)

Patent Claims: 1. Self-acting box magazine for rear-loading rifles with an upper opening of the magazine closing, downwardly opening pendulum flap A ¹ , the pivot α ^{2 of} which is mounted on the upper edge of the magazine eccentrically to the pressure direction of the cartridges and respectively. along the inclined lower surface of which the cartridges are guided to a lateral exit opening, a stop of the flap supported on the magazine wall preventing the cartridges from escaping vertically upwards after the magazine has been filled. 2. In automatic box magazines of the type specified under 1. an adjustable eccentric stop a ⁴ , by rotating the support point for the flap A ¹ changes and the same can thereby be kept in the lowered position, so that the lateral escape of the cartridges from the magazine prevents and the same will be retained in the magazine.
