Gun for firing telescoped ammunition

Abstract

A self-powered, belt-fed automatic gun for firing cylindrical, telescoped ammunition is described. Mounted in receiver portions of the gun, to which a barrel is connected, are a shell chamber, a chamber carrier assembly, a shell rammer assembly and shell feeding and casing ejecting assembly. The shell rammer and chamber carrier assemblies are mounted in the receiver for axial reciprocating movement, the chamber being interconnected with the carrier assembly so that recoil movement of the carrier assembly moves the chamber laterally from a firing position to a loading position, counterrecoil movement of the carrier assembly causing the chamber to move back to the firing position. Responsive to chamber movement from the firing position to the loading position a shell is moved into a feed position rearwardly adjacent to the chamber. Searing means are provided for enabling the rammer assembly to move forwardly in counterrecoil in advance of the carrier assembly, the rammer assembly ramming a shell from the feed position into the chamber, and thereby ramming a fired shell casing from the chamber into a forwardly adjacent ejecting chamber, before the carrier assembly is released for counterrecoil movement. A firing pin mounted on the carrier assembly causes firing of a shell in the chamber when the carrier assembly reaches its battery position.
