Abstract
An improved rotary device having means facilitating an increased power shaft diameter. This means includes a pair of gear elements which are not related to the eccentricity of the device or to each other in the conventional manner known in the prior art. To compensate for these discrepancies in such relationships, additional gear rotational means is needed to control the rotation and revolution of the altered gear structure to compensate for the failure to maintain the heretofore required relationships with the eccentricity and with each other. One embodiment of the invention utilizes a plurality of movement control discs to accomplish this gear compensating motion, while a second embodiment utilizes a plurality of compensating gears.
