Abstract
A chain rammer for ammunition includes a ram head, a rammer drive including two drive wheels connectable to a rotary drive for rotating the drive wheels and two separate chain strands each being connected with the ram head and each passing through the rammer drive for being driven in one of a chain advance and chain reversal direction by a respective one of the two drive wheels. The chain strands are arranged to come into abutting relationship at the rammer drive when driven in the chain advance direction and for separating from the abutting relationship at the rammer drive when driven in the chain reversal direction. Each chain strand includes chain links having hooks arranged to grasp an oppositely disposed chain link when the strands come together at the rammer drive in the chain advance direction to establish a firm mechanical connection between the two chain strands and so that such connection is released again when the chain strands move in the chain reversal direction.
