A mechanically or electrically operated toothbrush is actuated by a reversing switch operated by a movable handle section mounted over the housing of the toothbrush. The direction of the rotation of the toothbrush is changed by movement of the handle relative to the housing while the brush is applied to the teeth to provide the desired direction for the section of teeth being brushed.

Power-operated toothbrush

An electrically powered toothbrush with an eliptical brushing motion comprising a motor-operated rotating output drive and a disk rotatably mounted thereon, said disk having at least one eccentric funnel-shaped orifice which serves as an end bearing for a flexible direct drive shaft, a direct output shaft having one end bearing on said funnel-shaped orifice and the opposite end constructed as a holder for a brush, a second bearing for said shaft being located at a point between the two shaft ends, said output shaft having rigidity in one plane of the axis of rotation and flexibility in a perpendicular plane whereby an eliptical brush rotation is achieved as a result of tooth counterpressure again the brush, and a housing.
