ABSTRACT:
Two stage shell feeding apparatus for a reciprocating bolt-type automatic cannon or gun, comprises a first stage shell rotor, having a plurality of shell cavities, rotatably mounted between a shell supply and a cannon shell pick up position, such that when a shell in one of the rotor cavities is in the shell pick up position, an empty rotor cavity is in shell receiving relationship with the shell supply. After firing of the cannon and while the bolt is recoiling rearwardly, barrel gas operated actuating means cause rapid partial rotation of the rotor to index a rotor carried shell into the pick up position. A spring actuated, second stage shell advancing slide is simultaneously cocked to enable subsequent spring powered transferring of a free shell from the shell supply into the aligned rotor cavity during the remainder of the firing cycle. Shell accelerator means are provided to cause shell acceleration before bolt pick up impact. Configuration of the rotor cavities, a pair of feed lip members adjacent the shell pick up position and shell deflector means control movement of shells from the pick up position into a cannon firing chamber.
