PROGRAMMED SHELL CASING EJECTOR APPARATUS FOR AUTOMATIC CANNON ABSTRACT A programmed shell casing, ejector apparatus, for an automatic cannon having an axially reciprocating bolt assembly, includes an ejector member axially slidably mounted to the bolt assembly, a pair of cam tracks symmetrically fixed to a cannon mount, and a corresponding pair of cam track followers pivotally mounted to the bolt assembly to engage the ejector member and, as the bolt assembly recoils, the cam tracks. Ejection through an ejection port of a fired shell casing, held to a bolt face by an extractor, is caused when the ejector member is moved forwardly relative to the recoiling bolt assembly by the cam track followers as the followers move along the cam tracks. Timing and velocity of the shell casing ejection is programmed, to prevent cannon malfunction or jamming due to improper ejection or casing damage, by configuring the cam tracks and followers so that the ejector member moves for- wardly relative to the bolt assembly at controlled, increasing velocity preselected to be substantially less than recoil velocity of the bolt assembly. Also the cam tracks are configured so that engagement thereof by the cam followers is maintained during shell casing ejection and cam track - follower bouncing is prevented. The ejection member includes a pivotally mounting shell pick-up element for stripping an unfired shell from a loading position upon counterrecoil movement of the bolt assembly toward a gun breech.
