ABSTRACT:
An apparatus for loading shells in tubular weapons, particularly tank howitzers, comprises a linearly guided rammer engaging on the bottom of the shell, a pretensioned spring means driving said rammer and a release mechanism acting on the rammer and absorbing the spring tension in the locked position. In order to reliably absorb high ramming forces in a clearance-free manner and so as to suddenly release the same with a limited force requirement, the release mechanism has a fixedly mounted gripper, which cooperates by a planar effective surface with a planar opposite surface on the rammer. The effective surface and the opposite surface are in each case one face of a freely rotatably mounted polyhedron and, in the locked position, are at an angle less than 90.degree. to the force vector of the spring means. For releasing the rammer, the gripper can be pivoted by a release drive acting at right angles to the force vector.
