ABSTRACT:
Compressive force transmitting coupling (64) between an actuator (16), which oscillates along an arcuate path and a ram block (12) which reciprocates along a straight line path comprises first and second compression blocks (66, 68) and a bearing (70) between the compression blocks (66, 68). The compression blocks are in alignment and in compressive engagement with the ram block (12) and actuator (16). The compression blocks have opposed concave cylindrical bearing surfaces (72, 73) and the bearing (70) has oppositely facing convex bearing surfaces (74, 75) which are complementary to the concave surfaces (72, 73) of the blocks (66, 68).
