ABSTRACT:
A brush has bristles that tilt laterally out in a first position and tilt laterally in in a second position and are moved back and forth between the two positions to provide a brushing action. The bristles shown are mounted on a flexible membrane that is in an outwardly extending convex configuration to dispose the bristles in the first position and in an inwardly extending convex configuration to dispose the bristles in the second position. A bladder filled with a non-compressible fluid and an electric solenoid are used to move the flexible membrane between the two positions in a continuous cycle.
