Abstract
Rotary toothbrush utilizes a longitudinally extending hollow barrel having a fore-end and a rear-end. Longitudinally extending and reciprocatable strokearm mechanism is predominately located within the hollow barrel but includes a forward-portion always located forwardly of the barrel. A pair of transversely separated, upright rotary brushes are positioned wholly forwardly of the barrel and there eccentrically journal crankshafts carried by the strokearm mechanism forward-portion so that strokearm reciprocations cause the two brushes to move together in alternating angular directions. The strokearm mechanism forward-portion might be provided with auxiliary bristles for simultaneously brushing the dental occlusial surfaces as the rotary brushes treat the bucal and lingual surfaces.
