ABSTRACT:
A cleaning and plating method and apparatus comprising a plurality of tank assemblies arranged in series through which a batch of articles to be cleaned and plated is moved successively. Each tank assembly comprises a tank containing liquid treating or plating material. A barrel is at least partly submerged in each tank and is rotated about its longitudinal axis. The ends of the barrel are open and the barrel is formed with baffles on the interior thereof. When the barrel is rotated in one direction, the articles are agitated through the liquid and when the barrel is rotated in the other direction, the articles are elevated and deposited on a chute for transfer to the next succeeding tank assembly. Anodes and cathodes are positioned within at least some of the barrels and provision is made for elevating the anodes and cathodes out of contact with the parts or liquid in the tank assemblies when the barrels are rotated in the other direction to transfer the articles and thereafter returning them into control with the liquid.
