ABSTRACT:
A device providing reciprocating drive for a vehicle having a sprocket or drive wheel rotatably mounted on a frame. The mechanism is operable to reciprocally rotate a pair of independent hubs which impart a torque on such a wheel in a known direction when rotated in one direction and impart no force when rotated in the other direction. Included in the mechanism is a pair of spaced-apart sheaves rotatably mountable on such a frame and lever arms for applying rotational force to the sheaves. In one preferred embodiment, each sheave is operably attachable to a different hub. A pair of opposing cables with an end fixed on the rim of each sheave extend around separate idler pulleys interposed the sheaves in such a manner that the cables apply opposing rotational forces on each rim when placed under tension. The cables may be connected in such a manner that only one of the sheaves tends to rotate a hub in a torque-imparting direction.
