Abstract

A powered toothbrush is provided with a pair of disc-like rotary brushes (9) mounted for rotation about an axis (28) generally perpendicular to the length of the brush. The rotary brushes (9) are in axially spaced relationship and are provided with inwardly directed bristles (92). Between the rotary brushes, upper and lower brushes (6, 8) are mounted above and below the axis of rotation for linear reciprocating motion generally perpendicular to that axis. The upper brush (8) has upwardly directed bristles (80), and the linear brushes (6, 8) are mounted to the rotary brushes (9) so as to be brought into reciprocal. Linear movement when the rotary brushes are reciprocated angularly. Reciprocal motion can then be applied to one of the linear brushes (6, 8, or to the rotary brushes (9), in order to bring the entire mechanism into reciprocal motion.
