Apparatus for selective electrolytic plating
First Claim
1. Apparatus for the electroplating of parts, wherein the parts are interconnected in the form of elongated strip material wherein the metallic strip material is moved in a path which extends lengthwise of the apparatus, said apparatus comprising a plating brush means comprised of an elongated body member having its long axis extended parallel to the path of movement of the strip material, said body member having a substantially uniform cross-section throughout its length whereby a brush plating surface is positioned adjacent and in parallel relationship to the path of travel, said body member being composed of a hydrophobic material having interconnected pores dispersed throughout, means including a centrally located distribution conduit extending the length of the body for distributing liquid electrolytic plating solution under pressure into the pores of the body member along the length thereof, said plating brush means further including anodic means for imposing a uniform charge on the liquid plating solution passing from the distribution means to the plating surface and means for moving the metallic strip material from one end to the other of said lengthwise extended body member in contact with said brush plating surface.

Abstract
Selective electrolytic plating of small interconnected parts at high rates of production is disclosed. A porous hydrophobic material serves as the body of a brush member which has surfaces configured to transfer charged electrolytic solution to the selected surfaces of the parts being plated. Electrolytic solution is delivered under pressure to the interior of the body member.

14. Electroplating apparatus for transferring a coating of metal to an elongated metallic strip material wherein the strip material is moved in a path extending lengthwise of the apparatus;
- comprising a brush, said brush being composed of an elongated body member having its long axis extending in parallel to the path of movement of the strip material and having a brush plating surface adjacent to and in parallel relation with the path, said body member being composed of a microporous, hydrophobic synthetic resinous material, a centrally located distribution conduit extended lengthwise through the body member, said distribution conduit having circumferentially spaced openings distributed lengthwise thereof for passage of electrolyte solution uniformly through said hydrophobic material, means for moving the metallic strip material lengthwise of the brush with the parts in contact with the plating surface and plating circuit means comprising an anode and cathode for transferring uniformly charged plating solution from the brush member to the said metallic strip.
