ABSTRACT:
The present invention converts longitudinal motion into rotary motion. A reciprocating piston (that may receive a motive force from any desired means) oscillates longitudinally on a drive shaft. Extending through the piston parallel to the drive shaft is at least one ratchet pin that has a sprague clutch attached thereto by a ratchet arm for turning the drive shaft in one rotary direction. Also extending through the piston is at least one angle pin anchored in each end of a housing for the piston, which angle pin is at a slight angle with respect to the drive shaft and the ratchet pin. The slight angle causes the ratchet pin to arcuately move back and forth as the piston oscillates longitudinally. The arcuate movement of the ratchet pin causes the sprague clutch to turn the drive shaft. An adjustment of the slight angle may be provided to infinitely vary ratios of longitudinal movement to arcuate movement. By including two ratchet pins with sprague clutches, two angle pins, and a multilayered piston, the drive shaft can be driven for both directions of longitudinal movement of the multilayered piston.
