Multi directional oscillation from a rotational source
Abstract:
The present invention provides multi-directional oscillation from a rotational source, by receiving a rotational motion, converting the rotational motion to a first oscillating motion, converting the first oscillating motion to a second oscillating motion that is normal to the first oscillating motion and transferring the first oscillating motion and the second oscillating motion to a working element.
