ABSTRACT:
A brush is rigidly attached to one end of a housing having a handle at the other end and, between the ends, a cylindrical opening supporting a rotor whose center of mass is displaced laterally from the axis of rotation. As the rotor turns, it exerts an unbalanced centrifugal force on the housing, causing it to oscillate. The rotor is preferably a single metal roller gyrating or rotating about the axis of the cylindrical opening, and it may be rotated by a tangential stream of fluid, e.g., water at utility district pressure. The rotor body may be solid or a hollow member filled with a heavy liquid such as mercury, and it is so supported that during rotation its outer peripheral surface approaches but does not touch the borewall of the opening in which it operates.
