ABSTRACT:
An alternate ammunition belt feeder for selectively feeding one of two types of ammunition from two separate ammunition belts via two separate cartridge feeding stars into the linear breech pocket of an automatic fire arm, such as a machine cannon. Two cartridge feeders, which include the two cartridge feeding stars are adapted to coact with one piston-cylinder arrangement forming an energy converter which converts a portion of the pressurized gas which forms during firing into mechanical energy for driving the piston cylinder arrangement. The cartridge feeders are operatively mounted in a housing which is pivotally mounted in the weapon so that it can be swung from a first operative position via an intermediate inoperative position to a second operative position. Thereby the housing can be selectively positioned between the first and second operative positions and cartridges from a preselected feeders can be fired from the weapon by being positioned for entrainment by the breech block of the weapon. The cartridge feeding stars are mirror-symmetrically mounted in the housing which includes a bisecting U-shaped foot portion. When the housing is in the intermediate position no actuation of the piston cylinder arrangement is possible and the breech block of the weapon is free to reciprocate without engaging the U-shaped foot portion of the housing.
