A cartridge feed system for an automatic gun comprising a drum magazine possessing a number of chambers, the drum magazine being rotatably mounted about a drum shaft connected with the gun mount and incrementally or step-wise drivable. A first feed device is provided which moves the cartridges out of a respective chamber of the drum magazine and such first feed device is arranged stationarily externally of the drum magazine. A storage is disposed between the drum magazine and the gun and possesses two channels. The storage with the channels is arranged to be displaceable and each channel selectively can be shifted or displaced into a work position and into a rest position for the selective firing of different types of ammunition. A second feed device is provided which moves the cartridges out of the storage and delivers such to the gun, while the drum magazine is further rotated through one indexing step.

Cartridge feed system for an automatic gun

A weapon system containing a gun mount upon which there is mounted to be pivotable about an elevation alignment axis an automatic firing weapon or gun containing an ammunition container or magazine. A reloading container having an ammunition outlet opening is arranged at the gun mount. There is provided a conveyor device, by means of which sets of cartridges located in the reloading container can be brought to the outlet opening from which location these cartridges can be refilled into the ammunition container. The reloading container is displaceably arranged at the gun mount and its outlet opening can be brought into alignment with an inlet opening of the ammunition container which has been pivoted into an ammunition loading position. The conveyor device comprises transport elements which can be moved together with the sets of cartridges out of the reloading container into the ammunition container.

Weapon system equipped with reloading container

An automatic weapon equipped with at least two cartridge magazines from which loose cartridges can be conveyed into a common discharge channel, and a device for switching the cartridge infeed from one cartridge magazine to the other. The switching device embodies mechanism which can be selectively adjusted into two positions independent of emptying of one of the cartridge magazines. By means of the mechanism the cartridges in each instance can be fed, in one position of the mechanism, from the one cartridge magazine into the discharge channel and at the same time are blocked in the other cartridge magazine.
