Date Sep. 5, 1991.An apparatus for converting reciprocating motion to rotary motion and vice-versa. The apparatus includes a reciprocatory assembly guided for reciprocation in a first direction. The reciprocatory assembly includes first and second reciprocating members each terminating in a planar guide surface transverse to the direction of reciprocation; spacing tie means interconnecting the two reciprocatory members at opposite ends of the guide surfaces to maintain the guide surfaces parallel, spaced apart and facing each other; a drive block having opposed guide faces each slidably engaged with a respective one of the guide surfaces of the reciprocatory members; and a rotary member mounted for rotation about an axis transverse to the direction of reciprocation and having an eccentric portion rotatably engaged in the drive block.
