ABSTRACT:
A method and apparatus are provided for translating the speed of a drive shaft which is driven at a first speed to the speed of a driven shaft at a second speed, by providing a drive cam, a driven cam, and at least one reciprocating transfer element driven at a constant angular velocity and held in a slotted, fixed retainer, for interacting the two cams, such that the driven cam can be driven at the second speed by the drive cam driven at the first speed.
