Dual shell feeding apparatus, with shell accumulators, for automatic guns

摘要

Dual shell feeding apparatus for a dual shell supply automatic gun and the like includes a shell rotor mounted in rotational shell transferring relationship between the two supplies and a shell pick up position of the gun. The rotor is stepped in one rotational direction to feed from one shell supply and the opposite direction to feed from the other supply, shells being fed into the rotor from the supplies according to rotor rotational direction. Selecting apparatus enables prefiring selection of rotor stepping direction and hence shell supply selection for a next firing. A shell accumulator is provided for temporarily holding shells left in the rotor when a firing sequence stops. In response to the selecting apparatus selecting a different one of the shell supplies for feeding the gun during a next firing sequence, shells left in the rotor from the previously selected supply are transferred to the accumulator while shells previously transferred into the accumulator from the just selected supply are transferred back into the rotor for firing.
