Abstract
For installation in confined areas, an externally driven automatic weapon includes an alternatable dual cartridge supply system having two supply chutes are disposed parallel to an axis of symmetry traversing a cartridge supply rotor and a control roller for the breech block drive. The internal guide surfaces of both chutes are formed by a central guide disposed on the axis of symmetry, with the maximum width of this central guide corresponding to the chord length of a segment of the rotor which is provided with three, symmetrically disposed recesses, so that the introduction of cartridges into the rotor from the linear cartridge chute can take place, for example, directly from the top. The supply of cartridges to the rotor is always effected during any given period of time from only one chute. If cartridges are supplied from the other chute, the direction of rotation of rotor changes so that the cartridges are transported directly from the waiting position of a respective supply star wheel associated with each chute and fixed to the weapon housing, into a recess of the rotor and are transferred by stepwise movement of the rotor to a breech block for further transport into a cartridge chamber. During the continuous supply of cartridges by a further star wheel fixed to the cradle housing to the star wheel fixed to the weapon housing, guide means guide the cartridges in the axial direction within the chutes. To eject cartridge casings, a guide lever associated with the chute not then being used to supply cartridges is pivoted into the associated chute in the lateral rotor region to direct the empty cartridge casings into a casing chute.
