ABSTRACT:
A compact, reliable lightweight variable diameter drive mechanism for use with either a belt or a chain comprising outwardly biased, frusto-conical axially movable pulley halves and an automatically adjustable, flexible contacting surface wrapped around the pulley axle. The contacting surface is capable of imparting significant amounts of traction to the belt or the chain riding on the pulley halves. The contacting surface automatically varies its circumference as the pulley diameter changes. Tension on the flexible contacting surface is maintained by retracting one end into the hub of the pulley as the pulley halves are axially adjusted.
