ABSTRACT:
An improved mechanism is disclosed for varying the radius of gyration of a plurality of gyrating masses and for selectively changing the direction of the resultant unbalanced force produced by these gyrating masses. The improved mechanism is comprised of a pair of normally non-rotating, eccentrically disposed, circular cams which engage a pair of cam followers which are attached to connecting rods which in turn are connected to the gyrating masses. The direction of the resultant unbalanced force is selectively changed by simply rotating, in unison, the pair of normally non-rotating cams.
