Abstract: A powered wheel system wherein a rapidly rotating wheel carries weighted balls upwardly to load the downward side of a slower rotating power wheel to drive the same. The balls are unloaded at the bottom of the power wheel and then picked up by the rapidly rotating wheel and the cycle repeated.In another embodiment, the rapidly rotating wheel is driven by a connected drive-wheel, which carries a plurality of ball weights in an eccentric loop, inwardly on the upward side and outwardly in the downward side of such drivewheel as it rotates.The power wheel drives a flywheel which has reciprocably moveable weights mounted thereon, a plate with an eccentric guide path is provided which directs the weights inwardly on the upward side of the wheel and outwardly on the downward side of the wheel as the wheel rotates.
