Plating barrel assembly
Abstract
Abstract A plating barrel is suspended from hangers one of which has an opening coaxial with a corresponding opening in one end wall of the barrel. A tubular perforated partition is coaxially arranged in the barrel and conformingly received in the openings of the end wall and of the hanger for providing support to the barrel at one axial end. The other axial barrel end is supported by means of four contact rods which axially pass through the other end wall into the annular compartment between the barrel shell and the partition. The rods are connected by a coaxial spider outside the barrel cavity, and the spider is journaled in the other hanger which is metallic. The barrel is turned by a chain trained over a sprocket on the spider. The capacity of the annular plating compartment can be changed by replacing the partition by another one of different diameter. A perforated, tubular, insoluble anode of smaller diameter than the partition is coaxially arranged in the same.
