ABSTRACT:
An actuating mechanism installed intermediate the ends of a shaft without access to an end of the shaft is operative to perform a function requiring motion while the shaft is rotating. It includes a split hub mounted on and around the shaft, split ring gears carried by the hub but freely rotatable with resepct thereto, a pinion mounted to be rotated by and to engage the teeth of both ring gears, a drive train operated by the pinion, and preferably electro-magnetic brakes for selectively slowing one of the ring gears with respect to the other without engaging the ring gear, to cause the pinion to rotate.
In the embodiments illustrated and described, the pinion is operatively connected to a weight movable with respect to the shaft to permit balancing of the shaft while the shaft is rotating.
