Abstract
A method of feeding rounds of linked, or un-linked, ammunition to a gun includes a motor-driven chain drive which rotates about a track. A rotatable feeder engages the ammunition to feed an ammunition round into a round extractor/retractor. A rotatable round positioner receives an ammunition round from the round extractor/retractor, and rotates it to a firing position. A main geneva wheel, mounted near the chain drive, is sequentially engaged by first and second drive rollers, secured to the chain drive, for being periodically rotated thereby. Drive pins of the main geneva wheel sequentially engage radial slots in a belt/round feed geneva wheel and a round positioning geneva wheel for timed rotation thereof to synchronize the operation of the round feeder and round positioner.
