A plurality of pulley members are spaced equiangularly about and secured to the other end of the ram with the rotational axes thereof being perpendicular to the axis of movement of the ram. A piston is slidably seated in the passage in the ram and is driven in reciprocating movement by an air cylinder operatively connected to the end thereof adjacent the pulley members. Chain members equal in number to the pulley members are connected at one end to the aforementioned end of the piston and at the other end to the support at a point spaced axially of the ram from the pulley members toward the head portion thereof, each chain member extending intermediate its length about one of the pulley members.
