ABSTRACT:
The present invention provides an improved drive mechanism for reciprocating engines primary adapted for converting reciprocating motion of a piston within a cylinder to rotary motion which includes a piston and piston leg assembly which moves solely axially within the piston chamber with two rack gear members secured to the sides of the piston leg. A power driveshaft and an idler driveshaft are positioned on opposite sides of the movable piston leg and include a plurality of gears thereon positioned adjacent to each piston chamber for receiving driving movement therefrom. This longitudinal movement of the piston is converted to rotational movement of the shaft through the rack gears and power and idler gears which are connected to the power driveshaft and the idler driveshaft through a unique configuration including clutch bearings adapted to convey power driving movement responsive to movement of the pistons toward the crankshaft and to be freewheeling during movement of the pistons away from the crankshaft. The power driveshaft and idler driveshaft are mounted parallel with respect to one another and are interconnected by drive gears. Power output is provided at the power driveshaft rather than at the crankshaft in a more conventional reciprocating piston engine configuration.
