Abstract: An oscillating ratchet style continuously or infinitely variable transmission is disclosed herein, that is, one which, in its operation, relies on a plurality of different successive intermediate rotations that vary in speed and direction in accordance with their own respective oscillatory waveform, each waveform being out of phase with one another in a predetermined way. These intermediate rotations are used to convert the rotational input to a plurality of uni-directional output rotations, without the said of any over-running clutches. These later outputs vary in speed in accordance with their own respective waveforms and are used to produce a modified rotational output.
