ABSTRACT:
An infinite speed transmission having aligned input and output shafts with the input shaft driving a pair of eccentrics each of which oscillates an arm which in turn drives a gear plate housing in a rectilinear manner. Each gear plate housing slidably carries a gear plate equipped with multiple gear racks which drive a pinion gear mounted on the transmission output shaft. Gear plate and pinion engagement for unidirectional rotation of the pinion gear is controlled by a cam which shifts the gear plates within their respective housing. Speed changes are effected by relocating the eccentric driven arms relative the gear plate housings driven by the arms. Repositioning of the cam results in the output shaft mounted pinion being driven in a reverse direction.
