601,994. Electroplating apparatus. WIRE PROCESSING CORPORATION. June 13, 1945, No. 15032. Convention date, May 8, 1944. [Class 41] Wire or the like in the form of a helix is mounted on a rubber-covered shaft 10, by rotation of which the wire is caused to pass through an electroplating bath and, if desired, other baths, the wire being maintained in firm contact with the shaft by a rubber-covered roller 15, the pressure being adjustable by screws 17, 18. Spacing is maintained by a comb 27 and in the plating bath 33 by a member 41. Electrical contact to the coil is made by rollers 37 carried on arms 38 and anodes are positioned inside and outside the coil. Pre-plating and post-plating treatments may be effected in separate baths on each side of the plating baths. Where more than one layer of metal is required, the coating may be prevented from oxidizing between the different baths by spraying solution on the wire or by total immersion. The apparatus described will handle wire from # inch to 1 inch diameter and deposit coatings up to 50 per cent of these diameters. The plated wire may be drawn down to the required diameter.
