Power transfer device
US 4438656 Abstract
An improved power transfer device utilizes an input power source supplemented by an unbalanced weight assembly which increases the torque on an output shaft as a function of load associated with the device. The input shaft is provided with a drive gear in operable engagement with an internal toothed ring gear, and the ring gear is provided with a plurality of diametrically opposed, radial extensions to which weight support arms are pivotably attached. The remaining free ends of the weight support arms are attached to the outer extensions of a cruciform support and are further in parallel alignment with and fixedly secured to elongated weights, such securement being offset from a central portion of the weights. A difference in load between the input shaft and output shaft results in the ring gear shifting in an unbalanced manner relative to the output shaft so as to deliver an additional torque to the shaft through the shifting of the unbalanced weights.

Here is something worth working on, with the CNC machines we have now this could be much easier to make. Aln
