ABSTRACT:
An electrostatic, coating-dispensing apparatus includes an electrode upon which an electrostatic potential is impressed. The electrostatic potential is developed by a switching circuit, autotransformer and voltage multiplier from rectified line voltage. The entire apparatus is housed in a hand-held applicator to which line voltage is supplied. The apparatus includes a socket defined at one end thereof for interchangeably receiving containers holding various colors or types of coating material. Each container includes an electrode for contacting the first-mentioned electrode. The containers are shaped to fit snugly into the socket to hold the two electrodes in contact. An outer end wall of each container has a mesh portion through which charged particles of coating material from the interior of the container pass when the apparatus is activated.
