1. Apparatus for electrodepositing a selected metal onto a surface comprising an electrolytic solution, means for containing said electrolytic solution, an anode of the depositing metal in said electrolytic solution, a cathode in spaced relation to said anode in said electrolytic solution, one side of said cathode being the surface on which said selected metal is deposited, a pair of metal screen electrodes intermediaate said anode and said cathode in said electrolytic solution, means for electrically interconnecting said pair of electrodes, means for positioning one of said electrodes in close proximity to said cathode, means for positoning the other of said electrodes between said node and said one of said electrodes, and means for periodically reversing the positions of said pair of electrodes whereby said metal is uniformly deposited on said cathode side from the electrode in close proximity thereto substantially independent of the position, size, and shape of said anode.
