ABSTRACT OF THE DISCLOSURE An apparatus for providing a reciprocating motion. The apparatus has a housing block that contains twin piston guides in spaced apart rela- tionship to one another. The piston guides each contain a piston that has a gear rack. The gear racks are connected by a pinion gear so that the move- ment of one piston will cause an equal and opposite movement of the other piston. The movement of the pistons is controlled by the application of a fluid pressure to one or both of the pistons. The travel of the pistons is limited by a mechanical stop at one end and a fluid cushion device at the other end. Tools for the altering of a workpiece may be attached to one or both ends of the pistons. In one embodiment the apparatus is subjected to a rotary displacement achieved through the linear motion of one of the pistons.
