ABSTRACT:
A chain driven and receiving, continuously infinite variable speed transmission system comprising a pair of cones positioned in the same plane with the smaller diameter of each cone in proximity with the larger diameter of the other and encircled by a continuous flexible chain having pins extending therefrom for engagement and disengagement with spiral gears on the cones positioned in grooves parallel to the longitudinal axes of the cones. Either of the cones may be driven and the chain transmits the power to the other cone at a speed determined by the position of the chain relative to the cones. The system employs a planetary gear system for zero and reverse rotation of the variable speed output from the driven cone.
