ABSTRACT:
A mechanical transmission with a variable speed ratio that generates two oscillatory rotary motions that may have the velocities thereof selectively increased or decreased by concurrently increasing or decreasing the effective lengths of a pair of crank arms, with one of the oscillating rotary motions being rectified by two over riding clutches to become a pulsating rotary motion in a constant direction, and the pulsating and oscillating rotary motions thereafter being combined by a differential to result in a fixed ratio of output to input velocity for each setting of the pair of crank arms.
