Claim:
1. A handheld skin exfoliating apparatus comprising: a handle portion adapted to be held in a hand of a user; a head portion connected to the handle portion and having opposite sides; a first drum having a first outer surface, the first drum being mounted for rotation to the head portion with at least part of the first outer surface being exposed at one of the sides of the head portion; a second drum having a second outer surface, the second drum being mounted for rotation to the head portion with at least part of the second outer surface being exposed at an opposite one of the sides of the head portion; the first outer surface being abrasive to skin of the user and having a first level of abrasiveness; the second outer surface being abrasive to the skin of the user and having a second level of abrasiveness that is different from the first level of abrasiveness; and drive means mounted to at least one of the handle and head portions, the drive means operatively connected to each of the first and second drums for rotating each drum at a rotation rate sufficient to exfoliate the skin when respective ones of the first and the second outer surface contacts the skin, the drive means further comprising a motor having a shaft with an end extending beyond a side of the motor, and a gear train engaged between the end of the shaft and a respective one of the drums, the gear train comprising a shaft gear connected to the end of the shaft, a double gear having a large diameter portion meshed with the shaft gear and a small diameter portion, the double gear being rotatably mounted on a swinging shaft, the swinging shaft being slidably and rotatably carried in at least one channel, whereby the double gear swings between opposite operative positions on each one of the opposite sides of the head portion, an intermediate gear being located at each one of the sides of the head portion, each one of the intermediate gears being alternatingly meshed with the small diameter portion of the double gear when the double gear swings to each of the operative positions at respective ones of the sides of the head portion, and a drum gear connected to each drum, each drum gear meshed with a respective one of the intermediate gears; wherein the head portion is curved in a plane transverse to a major axis of the handle portion so that the opposite sides of the head portion and the drums which are carried within the head portion are forward of a central part of the head portion to better expose the outer surfaces of the drums in use.
