ABSTRACT:
A paint applicator which is rotatably powered, which draws paint from a supply container and ejects it against a flat surface through the center of a rotating disc, with the surface of the disc serving to rotatably brush the ejected paint on the painted surface. The applicator incorporates a cylindrical housing that encloses a rotatable worm gear linked to a rotatable jaw attachable to an electric drill chuck. A paint supply tube is joined to a collar rotatably mounted about the housing, with openings in the housing wall connected to the interior of the collar for drawing paint from the supply tube, through the collar into the interior of the housing. The worm gear ejects the paint through a perforation in the center of a disc attached to the free end of the housing, with fiber projections along the periphery of the disc serving to brush the ejected paint onto the painted surface. The housing and attached disc are joined to the rotatable worm gear drive by an adjustable friction collar so that the housing and attached disc may rotate at a different speed than the worm gear, when the unit is attached to a portable electric drill motor or other rotatable power drive mechanism.
