ABSTRACT:
A mechanical force enhancer for the amplification of a force generated by a pneumatic cylinder that is mounted at one end of a pair of spaced apart side plates. A piston rod attached to the pneumatic cylinder is in turn connected to a translatable link that is guided partially by complementary grooves contained in the side plates. After the link has translated through a prescribed distance, the end thereof most remote from the cylinder rod end is stopped against translatory movement thus permitting the link to rotate. A tool containing ram is attached to the link intermediate the stopped end and the rod attachment end. The continued rotation of the link provides an amplification of the force delivered by the cylinder ram thus permitting the tool to do useful work.
