Box magazine. Patented in the German Empire on May 31, 1910.

The invention relates to bottom loading, fully enclosed magazines with a bottom that can be folded down and a spring-loaded bottom, too cartridge feeder that folds downwards. Forms the subject of the invention a further development of these box magazines, which are known per se, which consists in that the feeder lever and the magazine base are arranged so that they can move freely relative to one another that when rotating downwards of the feed lever this counteracts the magazine bottom as soon as it touches the same the effect of a specially provided bottom closing spring directly in the open Location takes with it, while the magazine bottom is closed when the feeder lever is turned upwards takes place automatically under the action of the bottom spring. Through this

ao new design of the box magazine, the advantage is achieved that the feeder lever in contrast to the well-known magazines, with which he is in constant contact with the magazine floor is freely movable from the outside within the closed magazine is, and that it is not necessary to support the spring of the feed lever against the magazine bottom, which is a special Requires closure of the magazine bottom on the magazine box. Furthermore, a magazine, According to the invention over the other magazines of the same genus the considerable progress on that with him there are no transmission links between the magazine base and the feeder lever are absolutely necessary when the movement of the feed lever when Opening of the magazine is dependent on the movement of the magazine base, and moreover the feeder when opening the lid one in relation to the movement of the lid need to give accelerated movement.

In the drawing, the subject of the invention is in Fig. Ι in longitudinal section, for example while FIG. 2 shows a cross section through the magazine according to 2-2 of FIG.

A feeder lever c rigidly connected to a rotary shaft b is arranged within the box-shaped magazine housing α. The rotating shaft b is in turn rotatably mounted in the side walls of the magazine α and has a handle d on one side outside the magazine. When the magazine is closed, the feeder lever c is lifted continuously along the path of the breech block by the bow spring e, which tends to spread itself. For this purpose, the eye of the bow spring e is attached to the bolt f arranged in the magazine and its lower arm abuts the bolt g also provided in the magazine housing. On the upper arm of this bow spring e , a chain link i is articulated at h , which is articulated at its lower end at k with the feeder lever c . In addition to the spring e for the movement of the delivery lever is an equally configured and operating spring I, which frequently has the tendency to the magazine bottom η to be brought into the closing position, and also m by means of a chain link η with the floor is hingedly connected, and this

consequently seeks to turn continuously upwards (Fig. 2). The magazine bottom η has on both sides of the delivery lever c situation tube c which grip the delivery lever fork-shaped and freely rotatable on the shaft b of the delivery lever are supported so that the movement of the magazine bottom η independently of the movement of the associated delivery lever rigidly b with the shaft c is.

The mode of operation of the magazine is as follows:

If the same is to be opened, the feeder lever c is rotated downwards by the outer hand lever d, against the action of the spring e. As soon as the feeder lever c comes into contact with the floor of the magazine, it takes it downwards with it, without any noise being produced by the movement of the magazine floor.

The feeder lever c together with the magazine base η is then rotated further downwards until the pivot points Ji, k and b (FIG. 1) come to their dead center position, ie are in a straight line. Purpose-

even this dead center position is slightly exceeded when opening, and that in this case occurring efforts of the feeder and the lid to open even further by suitably attached stops are limited.

After the magazine has then been filled from below, the magazine base η and the feeder are released from the dead-center position by pressure on the base, and these parts then automatically snap back into the closed position under the action of springs e and I, which takes place silently when one grasps the handle d for the purpose of braking this movement and thereby regulates the speed of closing the magazine base. As soon as the cover η has placed itself on the magazine housing α again, the magazine is again in an operational state. Instead of designing the magazine, as is assumed in the present exemplary embodiment, in the known manner as a clip-on type which can be carried away from the rifle when full, it can also be rigidly attached to any handgun.

Claims (1)

Patent claim: Box magazine to be loaded from below with a bottom that can be opened downwards in a vertical plane and a cartridge feed lever which is under spring force and which can also be opened downwards, characterized in that the inside of a completely closed magazine is freely movable and at the same time in a known manner by a handle (d) from the outside The feeder lever (c) to be moved when rotating downwards, as soon as it rests against the magazine base (s) under the action of a special closing spring (I) , takes it with it into the open position without the aid of any intermediate transmission links, while the magazine base (s) is closed during The feed lever (c) is turned upwards automatically under the action of the special bottom closing spring (I) . 1 sheet of drawings.
