ABSTRACT:
Force transmitting coupling (44) for transmitting force from an actuator (16) which oscillates along an arcuate path to a ram block (12) which reciprocates along a rectilinear path comprises a flexible member (50) coupling which is connected to the actuator (16) by a lost motion connection (90, 94) and which is against the ram block (12). The flexible member (50) is supported intermediate its ends in a manner such that it can flex by a predetermined amount but not more than the predetermined amount. When the ram block (12) is pushed from a retracted position to a forward position, the flexible member is placed in compression and flexes by only the predetermined amount. The force transmitted to the ram block is applied to the axis of the ram block.
