Abstract

A turret gun assembly includes a turret, a gun having a barrel being adjustable in inclination about a trunnion axis, a magazine for accommodating rounds of ammunition, and a loading device for advancing rounds of ammunition from the magazine into a position behind the barrel in a longitudinal alignment therewith. The improvement wherein the loading device has a cam drive having a cam track mounted at an ammunition discharge location of the magazine and a follower guided in the cam track; a transfer arm mounted for pivotal motion about the trunnion axis; an ammunition-gripping holding clamp articulated to the transfer arm by a hinge connection and being arranged for gripping said ammunition. The transfer arm is rotated about the trunnion axis for causing the follower--which is coupled to the holding clamp--to slide within the cam track to rotate the holding clamp and the round of ammunition about the hinge connection and to simultaneously swing the holding clamp and the ammunition gripped thereby, about the trunnion axis to position the gripped ammunition into longitudinal alignment with the barrel.
