Fig.7 ///fl r m GEORG AGREN INVENTOR WMJIM AID United States Patent ()1 MAGAZINE AND CARTRIDGE CLIP COMBINATION Georg Agren, Halsingborg, Sweden Application June 20, 1957, Serial No. 666,810 Claims priority, application Sweden February 8, 1957 7 Claims. (Cl. 42-50) The present invention relates to a submachine gun of a known type, and more particularly to its magazine and loading means.

A generally recognized drawback of this gun is that it takes too much time to fill the magazine from the ordinary ammunition boxes even if special means, for instance magazine fillers, are used. Under certain conditions, for instance in severe cold, the filling operation may besides be very difficult, and therefore a soldier equipped with a gun of this type is practically unarmed, after emptying the magazines issued to him, for a period which is disproportionately long in comparison with the time required for emptying a magazine by firing.

An object of the invention is to bring about an improvement in this respect by providing a new magazine, which has the additional advantage of being considerably lighter.

The invention relates to a magazine device for submachine guns and similar small arms, comprising a magazine mounted on the gun and provided in a known manner with a magazine spring secured to the bottom plate of the magazine which is provided with means for tensioning the magazine spring and keepingit in a tensioned state, and further has a lateral opening for introducing cartridges into the magazine, as well as a cartridge clip fitting inside the magazine and introduceable through its lateral opening, said clip having a loose bottom plate which is supported by projections in the clip in order to be actuated by the magazine spring so as to feed the cartridges into the gun.

Further objects and advantages of the invention will be apparent from the accompanying drawings showing an embodiment, chosen by way of example, of the device according to the invention.

In the drawings,

Fig. l is a partial side elevation of a submachine gun having a magazine device according to the present invention.

Figs. 2 and 3 are sections on line IIIII of the magazine respectively without and with cartridge clips.

Figs. 4 and S are sections on lines IVIV and VV in respectively Figs. 2 and 3.

Fig. 6 is a section on line VI-VI in Fig. 2.

Fig. 7 is a side elevation of a cartridge clip.

Fig. 8 is a view of a slidable catch in the right-hand bottom portion of the magazine.

The basic idea underlying thenew construction is that the cartridges are not to be introduced into the magazine one at a time but instead are to be introduced all at once. The cartridges are to be enclosed in a cartridge clip of for instance plastic or cardboard and filled at the ammunition factory. The clip can be thrown away after use. This makes it possible to keep the magazine attached to the submachine gun, and the soldier is equipped with filled cartridge clips instead of with spare magazines and boxes of ammunition.

In the drawings, there is shown a part of a subma- 2,910,795 Patented Nov. 3, 1959 chine gun I of a Swedish type having a magazine 2 which, like the magazines known until now, has a tubular shape with a trapezoidal section but which, unlike the magazines used until now, has an opening 3 in its righthand side, which covers the greater part of the height and width of that side. To the bottom 4 of the magazine there is attached a magazine spring guided by a guide pin 6 which is also attached to the bottom plate. At its upper end the spring has a spring head consisting of a plate 7 which is plane and which is provided with downwardly directed guide flanges 8, the front and rear ones of which are curved obliquely inwards. The guiding flange on the right-hand side is provided with an outwardly directed pin 9 having on its outer end a plate 10 with a handle 11 in the form of a leaf which can be turned up when not in use.

On its rear side and just above the lower edge of the lateral opening 3 the magazine has a catch 13 in the form of an arm which is pivotally mounted on a vertical pin 14 in one corner of. the magazine and provided with a leaf spring 15 which is supported by the rear wall of the magazine and tends to swing the catch into the magazine. On its front side the magazine has a similar catch 16 mounted on a pin 17 and provided with a leaf spring 18. Both catches are bevelled, as shown in Fig. 4, for cooperation with the front and rear guiding flanges of the plate 7.

On the interior left-hand side the magazine has an ejector leaf spring 19 which is secured to the magazine Wall at its upper end and which, when untensioned, is slightly S-curved and directed obliquely downwards towards the lower edge of the lateral opening of the magazine, as shown in Fig. 6. By pressing it down with a finger it is possible to press the spring flat against the left-hand magazine wall.

Figs. 3, 5, and 7 show a cartridge clip 20 shaped and dimensioned to fit into the magazine with such clearance that it can be pushed upwards into the upper portion of the magazine through the lateral opening 3, until its upper end is stopped by an abutment 21 (Fig. 6) in the magazine, in order then tobe introduced completely through the lateral opening. On the right-hand side the cartridge clip has a slot 22 extending from the lower end of the clip up to a point situated at the upper edge of the lateral opening of the magazine when the clip is introduced into the magazine. The clip has a bottom plate 23, the upper side of which is sectioned in the usual manner for two piles of cartridges disposed according to a zigzag pattern. The bottom plate is loosely laid on small inwardly directed projections 24 (Fig. 3) in the corners of the clip, without being attached to them. These projections provide free passage for the magazine spring plate 7 so that said plate can be moved up into the clip.

As mentioned before, the cartridge clip, which is meant to be used once and then thrown away, at least under war conditions, can preferably be made of plastic, possibly of cardboard. For this purpose a polyetene plastic of a suitable type is preferable because of its strength and other properties which make surface treatment unnecessary. When the clip is to be mounted in the magazine its upper end must of course be open, but in order that the filled clip may be handled and carried it must be closed, for instance by means of a cover or a strip of paper 25, which can easily and quickly be torn away immediately before the clip is mounted in the magazine. For safetys sake this closure member can be constructed in such a way that the clip cannot be introduced into the magazine in a closed state. Furthermore, at its lower end the clip can be reinforced by means of a strip 26 across the slot 22, which should preferably not be stronger than permitting it to be torn off by the pin 9 on the magazine spring plate 7 when said plate is moved upwards by the magazine spring. The pin may possibly have an edge on the upper side for that purpose.

Fig. 8 shows a locking device serving to retain the cartridge clip 20 in the magazine so that its lower portion cannot be moved out prematurely from the magazine by the ejector spring 19. The locking device consists, in the embodiment shown, of a slidable catch 27 in the shape of a fork, Whose prongs 28 project, in the locking position, above the lower edge of the lateral opening 3 on both sides of the pin 9 of the magazine spring plate 7 and the slot 22 of the clip 20. The shank of the fork is guided in two fittings 29 on the inside of the magazine wall and rests on a helical spring 30 which is supported on the magazine bottom.

The first measure taken at loading is to tension the magazine spring by moving the handle 11 downwards until its pin 9 is stopped by the bottom of a recess in the lower edge of the lateral opening 3 when the plate 7 is on a level with this. During the latter part of this movement the plate 7 moves away the

bevelled catches

13 and 16 with its oblique front and rear guiding flanges, and comes below them, whereby they move in over the plate. Simultaneously, the pin 9, by means of which the handle 11 is secured to the spring plate 7, hits the fork 27 between the prongs 28 and moves the fork downwards so as to leave the lateral opening of the magazine free. Thereafter, a cartridge clip 20, whose upper end has been opened, is introduced into the magazine in such a way that its upper end is pushed upwards into the magazine through the lateral opening, until said upper end comes into contact with the abutment 21, and so that its lower end may be pushed laterally inwards against the resistance from the ejector spring 19. During this operation the clip moves away the

catches

13 and 16, whereby the spring plate 7 is released and moved upwards by the magazine spring into the clip, lifting the loose bottom 23 so that the topmost cartridge reaches the breech of the gun. The pin 9 also takes part in the motion and releases the forked slidable catch 27, whereby the catch is pushed upwards by its spring 30 into the lateral opening of the magazine in order to retain the cartridge clip. Next time the magazine spring is tensioned and blocked for reloading, in which connection the slidable catch is moved away, the ejector spring 19 ejects the empty clip or at least moves its lower portion outwards to such an extent that the clip can easily be removed by hand and so that another clip filled with cartridges can be inserted, whereupon the gun is once more ready for firing.

It is evident that the invention is not restricted to the embodiment shown and described, which can be modified in various respects, for instance with regard to the construction of the catch or locking devices, without departing from the basic inventive idea.
