Abstract
Abstract An ammunition storage and feeding mechanism having a flexible endless metal conveyor belt spiralled into concentric turns about a common axis and disposed within an ammunition box, the inner belt turn being connected to the outer belt turn. The belt having abutments spaced in the lengthwise direction thereof to receive ammunition rounds having their lengthwise axes parallel to the common axis of the belt turns, the belt transferring the rounds to a rapid fire gun feeding mechanism located adjacent the radially outer layer of the belt. The belt is driven by a pair of sprockets respectively driving the inner and outer belt layers at the same speed with the outer empty belt layer portions becoming the radially inner belt layer portions as the belt is driven.
