ABSTRACT:
This invention is an articulatable mechanism applicable to a wide variety of situations. The device provides a rotational component as well as a pivotal component providing practical propulsion in polar coordinates instead of customary linear transmission. This device could be used for steering propulsion devices by controlling the orientation and direction of a propeller shaft or rocket exhaust. Another application of this device might be orienting and directing devices such as fire hoses and lasers.
