ABSTRACT:
A crank is rotatably mounted on a frame, and a roller is rotatably mounted on the crank at a radially displaced location. A force receiving member and a discrete support member bear against the roller. The roller links rotation of the crank relative to the frame to up and down movement of both the force receiving member and the support member and to back and forth movement of the force receiving member relative to the support member.
