ABSTRACT:
A variable power transmission for varying the power from a reciprocating power source to a rotatable axle shaft comprising a crank interconnecting the power source to a rotatable wheel through a crank pin, an inner wheel jack shaft with gears or sprockets mating with gears or chains loosely carried by the rotating wheel, a crank pin sliding block carrying the crank pin on one end and threadedly engaging the jack shaft at its opposite end, a counter weight threadedly engaging the jack shaft opposite the crank pin sliding block and brakes for selectively stopping the rotation of a selected one of the gears or chains whereby the jack shaft turns translating the crank pin sliding block and counter weight along the jack shaft.
