ABSTRACT:
The invention is a variable speed transmission for adjusting the output of a drive shaft. It comprises a journal mounted rotatable casing with an internal cyclical periodic track selectively pushed by a plurality of reciprocating push rods activated by a variably extendable cam mounted to a drive shaft. The torque ratios are directly proportional to the degree the push rods are extended by the extendable cam.
