ABSTRACT:
An electrostatic hand-held coating-dispensing apparatus includes a first pulley, a second pulley, and a continuous belt trained about the first and second pulleys. The first and second pulleys are supported and retained in spaced apart relation to maintain tension on the belt in a supporting housing. A first brush is provided adjacent the belt where the belt is trained about the first pulley. A second brush is provided adjacent the belt where the belt is trained about the second pulley. A curved conducting surface is also supported by the housing. The second brush is connected to the conducting surface. A small alternating current electric motor is provided for turning the first pulley. A container or canister is provided for the coating material. The canister is snugly received in the supporting housing in a position adjacent the conducting surface. The canister includes an end for transferring electrostatic potential from the curved surface to the coating material therein.
