Abstract
An apparatus for converting reciprocating motion to single direction rotational motion that includes a frame, a shaft supported by the frame for rotation relative to the frame, a first one-way clutch mounted on the shaft, a first pinion mounted on the first one-way clutch, a second one-way clutch mounted on the shaft a second pinion mounted on the second one-way clutch, a first bearing mechanism mounted on the shaft between the first pinion and the second pinion, a first rack engaging the first pinion for driving the shaft when the first rack is moved in a primary direction at a rate of speed sufficiently fast to overtake the shaft, a second rack engaging the second pinion for driving the shaft when the second rack is moved in a reciprocal direction at a rate of speed sufficiently fast to overtake the shaft, and an actuator in working relation with the first rack and the second rack.
