Abstract
A worm-like drive mechanism has a plurality of axially-spaced eccentrics rotated by an input shaft located at right angles to an output shaft. A wheel mounted on the output shaft has a circumferential surface with periodic undulations. Oscillators in the form of rollers mounted on pins and captured in respective slots of a fixed carrier are reciprocated through contact with the external surfaces of the eccentrics to cause the undulated surfaces of the wheel to move, thereby driving the output shaft. Contact between the rollers and the eccentrics is achieved through the intermediary of bars which are reciprocated with the rollers.
