Abstract
A cathode assembly for the electrodeposition of metals comprising in combination at least one edge stick engaging at least one edge of a cathode, wherein the cathode has at least one upstanding projection on each of its surfaces proximate said edge, the projections each having an upstanding face which is both substantially parallel to the proximate cathode edge and facing away therefrom, and wherein the non-conductive plastic edge stick is of channel-like form, the inner trough faces of the channel being adapted to engage securely with the projections proximate the cathode edge, thereby to retain the edge stick thereupon. This assemblage has the advantages of simplicity of construction and assembly, while also avoiding any weakening of the cathode edge.
Claims14
A cathode assembly for the electrodeposition of metals comprising in combination at least one edge stick engaging at least one edge of a cathode, wherein the cathode has at least one upstanding projection on each of its surfaces proximate said edge, the projections each having an upstanding face which is both substantially parallel to the proximate cathode edge and facing away therefrom, and wherein the non-conductive plastic edge is of channel-like form, the inner trough faces of the channel being provided with projecting lips at their outer edges adapted to move over the projections on each surface of the cathode proximate the cathode edge and to engage opposite cathode faces resiliently and securely, thereby to retain the edge stick thereon.
An assembly as claimed in claim 1 or 6 wherein the edge stick is fabricated from an acrylonitrile-butadiene-styrene copolymer.
A method of making a cathode assembly comprising in combination at least one non-conductive plastic edge stick engaging at least one edge of a cathode, which method comprises forming, proximate said edge of the cathode by deforming the metal of the cathode in a region proximate said edge, at least one upstanding projection on each face of the cathode, the projections each having a face which is substantially parallel to the proximate cathode edge and facing away therefrom;
- forming a non-conductive plastic edge stick of channel-like form having inner trough faces with lips at the outer edge of the channel trough faces projecting inwardly and adapted to move over the projections formed proximate the edge of the cathode and to engage opposite cathode faces both resiliently and securely;
- and applying the edge stick to the cathode edge securely and resiliently engaging the edge stick with the projections formed proximate the cathode edge.
