Abstract

The invention relates to a magazine of an automatic weapon, including a superimposed cartridge clip with bullets and two closed transmission chains which are tiltedly arranged relative to the cartridge clip, two jagged claws are arranged on the transmission chain to grasp the last bullet which is positioned at the bottom end of the cartridge clip to push the bullet to the weapon, a single chain joint of one transmission chain is enlarged in the height direction and the end side is provided with a lower end bearing surface which is used for the pushed bullet so as to attach the bearing on the bullet by the common action of the pushing step and the grasp in the cartridge clip.

Description

Bullet clip on automatic weapon

The invention relates to a cartridge magazine for automatic weapons, comprising a stack of cartridges with cartridges and two closed transport chains arranged obliquely to the cartridges, on which two serrated jaws are arranged for catching the last cartridge in the lowermost cartridge and pushing it out towards the weapon.

Such a cartridge clip is disclosed in swiss patent specification CH-a-669992. In which a small frictional force is generated when the cartridge is ejected from the cartridge holder, and the cartridge head is additionally supported by a pellet guide plate. In order to continuously eject the cartridges from the stack of cartridges in the lifting device, the conveying chain is arranged on an inclined plane and the stack of cartridges is moved downwards when the cartridges are ejected. At the same time, each time the clip projectile guide is pushed out, there is a saw-tooth movement, which results in a redundant mechanism.

The invention provides a technical solution in which no movement of the pellet guide plate and thus no redundant moving machinery is required in order to achieve support of the pellet in the lowermost pellet holder.

The advantage of this is that the cartridge is supported by the conveyor chain in the shoulder area of the case. In this way, the support is independent of the shape of the projectile head and friction losses between the auxiliary support and the ejected projectile are eliminated.

An embodiment of the cartridge clip of the present invention will be described in detail with reference to the accompanying drawings. Wherein,

FIG. 1 is a side cross-sectional view of the clip of FIG. 2 taken along line I-I;

fig. 2 is a sectional view taken along line II-II in fig. 1.

According to fig. 1 and 2, a cartridge 10 includes a number of cartridges 11. Each clip 11 comprises seven cartridges 12. The clip 11 will move downwards in the clip 10 as indicated by arrow a and the cartridge 12 will be pushed to the left from the lowermost clip 11 as indicated by arrow B. Finally, as indicated by arrow C, the cartridge 12 pushed out of the lowermost clip 11 will pass from the clip 10 through a curved channel 13 into the weapon 14, only the right corner of which is shown. The cartridge holder 11 is pushed by a closed transport chain 15, which is carried by two guide rollers 16 around which it is wound. On the closed conveyor chain there is hinged a catch 18 which bears against the clip 11 to be pushed. The lowermost clip 11 is supported on two screw feeders 30 and 31 for continuously conveying the clips 11 when the cartridges 12 are ejected from the lowermost clip 11. The cartridges 12 are pushed out of the lowermost clip 11 by means of two further closed

conveyor chains

19 and 20, which are guided by two deflection elements 21 and 22, respectively. As is clearly shown in fig. 2, the closed

conveyor chains

19 and 20 are inclined to the lower left, so that the cartridges 12 can be discharged from the magazine 11 both in the direction of the arrow B and in the direction of the arrow a of the magazine 11. The result of the compound movement in the direction of arrows a and B corresponds exactly to the inclination of the closed

conveyor chains

19 and 20. Two jaws 23 and 24 are provided on the closed

conveyor chains

19 and 20, respectively, which each bear against the last cartridge 12 of the magazine 11, thereby pushing all cartridges 12 in the magazine 11 to the left out of the magazine 11. The cartridge 12 that has been ejected from the magazine 11 is fed into the weapon 14 in the channel 13 by means of a further closed conveyor belt 25, also indicated as a lift, which is provided with lifting teeth 26 between which the cartridge 12 is located. The closed belt of the hoisting machine 25 is guided around the diverting members 27, 28 and 29. The cartridges described above are all of the prior art (see CH-a-669992) and the above description is essential to the understanding of the invention that follows.

In order to feed the cartridge 12 in the lowermost magazine 11 from the magazine 11 into the weapon without friction and precisely, that is to say into the elevator 25, the cartridge 12 must be additionally supported during the ejection step. According to the invention, the support is achieved in that at least one conveyor chain 19 of one of the conveyor chains that is used for supporting is trimmed in such a way that at least a part of the chain link 40 of one of the chain links is increased in height, thereby forming a lower support surface 41 for the cartridges 12 that have been ejected in the ejection step. For example, as shown in figure 2, six of the seven individual links 40, which are shown in duplicate, are trimmed to have corresponding lower bearing surfaces 41. The remaining two links 40 are still in their original shape to also conform to the conveyor chain 20. This ensures a precise support and a precise delivery of the pellet during the ejection step, not only in the magazine 11 but also at the shoulder of the pellet. With this trimmed link 40 no additional frictional losses are created between the lower bearing surface 41 and the ejected bullet 12.
