A self-cleaning brush having a brush body with a pair of sides, a back and a top, a backing member mounted within the brush body, the backing member having an arcuate upper surface, a flexible membrane extending between the sides of the brush body, a plurality of bristles attached to the flexible membrane, a component to urge arcuate upper surface of the backing member into contact with the flexible membrane such that the bristles will assume a convex configuration extending from one of the sides to the other of the sides, and a cleaning plate adapted to lie in juxtaposition to the flexible membrane, the cleaning plate having apertures therein through which the bristles extend. The arrangement provides for a self-cleaning brush wherein the cleaning plate is retained in position by the bristles and permits one to have a convex brushing surface.

[ I claim:] [1.] A self-cleaning brush comprising:(a) an elongated brush body having a top, a bottom and a pair of sides extending therealong;(b) a flexible member having opposite first and second surfaces wherein a plurality of bristles extending from the first surface thereof, said flexible member being secured at opposed edges thereof to the sides of the brush body, said flexible member being located adjacent the top of the brush body;(c) a backing member having a convex upper surface, said backing member being attached to the second surface to the flexible member at a vertex of the convex upper surface, the backing member being adapted for movement relative to the top and bottom of the brush body between a retracted position and an extended position whereby the convex upper surface abuts the second surface of the flexible member and causes the flexible member to assume a convex shape;(d) a support member disposed within said brush body between the backing member and the bottom of the brush body, the support member being movable and wherein movement of the support member causes the backing member to be moved between the retracted and extended positions; and(e) a cleaning plate removably attached to the brush body adjacent the top thereof, the cleaning plate having a plurality of apertures therein for receiving respective ones of the bristles.
