ABSTRACT:
The present invention relates to a multifunction variable speed drive. There is provided a drive pulley of variable effective diameter and a follower pulley of variable effective diameter, a flexible belt passing around both pulleys and means for applying adjustable forces to the drive pulley. A constant drive ratio between the pulleys is obtained when two opposing forces on the drive pulley are in equilibrium. The drive ratio between the pulleys falls with increasing load and vice versa.
