ABSTRACT:
Conveyors are provided for tumbling and transferring parts to be subjected to treatments, including electroplating in a series of treatment tanks. The conveyors are supported on the treatment tanks for pivotal movement between a position in which the parts are received from a parts feeder to a treatment position in which the parts are subjected to tumbling and immersion within a treatment solution to a drain position for during of the treatment solution and drying and next to a discharge position where they are discharged either to another conveyor in a next treatment tank or to a subsequent station for further processing. Movement of the conveyors to the several positions is carried out by tilt devices which vary the slope of the upper run of each conveyor. A plating tank includes anode baskets disposed adjacent the load-receiving end of the upper run of the conveyor and cathode danglers for contacting the parts on the upper run to establish a current path comprising danglers, the parts, the electrolytic solution and the anodes. Circulation of electrolyte is provided establishing a circulation path past the anodes through an inlet opening in the parts receiving hopper portions of the conveyor.
