ABSTRACT:
A variable speed chain drive includes a driven pulley which supports radially adjustable drivers, the drivers defining a wedge-shaped opening in which the chain is received and frictionally captured. The drivers, which may include cooperating clamp and drive members mounted from the disks which define the pulley, are positioned by an adjusting mechanism.
