ABSTRACT:
A transmission device for converting rotary motion into linear force by varying the centers about which the weights rotate comprising two impellers (off-centered weights) which rotate in opposite directions. Impellers will be mounted within a rocker element which will rock back and forth in a controlled sequence. The amplitude that the rocker element rocks will be controlled by a cam which will be directly geared to a large gear. The impellers will also be geared to the same large gear which will rotate at a controlled speed. However, the speed of the impellers will be constantly changing. As the rocker element rocks in the same direction as the large gear the speed of the impellers will decrease and increase when the rocker element rocks in the opposite direction of the large gear. A clutch device will connect the large gear to a second large gear which will be equipped with a large flywheel and provided with a source of power. Output force will be controlled by either varying the base speed of the large internally toothed gear and flywheel.
