ABSTRACT:
A machine for converting rotary motion from a source of power to a linear force comprising three small gears in mesh with one large gear, a rocker element, an impeller (off-centered weight), and a cam shaft. The first small gear will be provided with a source of power which will drive the large gear which in turn will drive the other two small gears, the second small gear, housed in the rocker element, will be provided with an impeller which when rotated will provide a source of centrifugal force, the third small gear, designated cam gear, will be provided with a cam shaft which will control the operation of the cycle. A rocker element with two arms will pivot about the same center as the large gear. Mounted within one of the movable arms will be the second small gear with an impeller mounted on the interconnecting shaft. The second arm will be extended to the cam for the control of the cycle. The path traversed by the impeller will be that of a modified ellipse with the impeller always on the outside of the cycle. As the impeller travels this path the centrifugal force generated, due to the fluctuations of speed and curvature of trajectory, will vary. It is this variation which will provide the conversion of rotational output to linear force.
