`York, inthe county of New York and State of New York, have invented certainl new and useful Improvements in Anodes and I Ado hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to new and useful improvements in the class of anodes used in electroplating.
The object of my invention is to produce a device of this class which may be so suspended in the bath that the metal anode is entirely submerged therein, thereby presenting its entire surface to the electrolytic action.
With anodes 'as heretofore constructed it has been impossible to thus 'submerge the entire metal anode, because b so doing the perfo rated ears of the anode an their supportinghooks would be exposed to the action of the solution, which would rapidly destroy the same, thus retarding and eventually entirely cutting ofl" the electric current therefrom, and thereby terminating .the process. The advantages of entirely submerging the metal anode are obvious and, briefly stated, are
as follows: First," a larger surface is presented to the action of the bath, and, secondly, waste occasioned by the lack of immersion is obviated. Furthermore, in practice it has been found that during the process of plating an oxid is frequently pron duced and deposited upon the anode, forming a non-conductor and setting up a resistance to the electric current.. In order to facilitate the removal of suchoxid from the anode, I so construct the same that it will present a smooth surface from which such oxid may be readily removed by scraping or the like. 1,
In order that my invention may be more thoroughly understood, I have illustrated the same in the accompanying drawings, a full and exact description thereof appearing in the annexed specification.
In the accompanying drawings, Figure lis a perspective view of my improved carbon plate or core. Fig. 2 is a perspective view of the metal anode. Fig. 3 is a perspective view of my improved device suspended from the rod. Fig. 4 is a vertical section through my improved device.
In the several views like letters of reference designate similar parts of my improved construction.
A in the drawings designates a carbon plate or core provided at its upper end with ears a a and at its lower end with the en larged portion a preferably covered with insulation a?.
B is the4 metal anode of sheath-like construction, being provided with the longitudinally-extending opening b of Sufficient size to permit said metal portion to be slipped onto said carbon plate lorcore', as shown in Figs'. 3 and 4, the enlargement a of said plate A forming asupport therefor, as clearly shown in Fig. 4. Although said metal portion may be of any desirab e shape, it is preferably tapered upward, the thickest ing on the enlargement a struction it is obvious that the upper portion of the metal would be first destroyed, thus decreasing the area of the surface exposed to the electrolytic action; but in order to overcome this and maintain the desired area I utilize new sheaths'by sli ping them onto the carbon 'plate as the meta anode wears away.
e It is obvious that metal sheathscould be made of varying sizes to be employed in compensating for the destruction of the metal, as above described.
C is a band of insulating material incasing the exposed ortion of the carbon plate or core a ove t e metal portion, by Imeans of which construction it is apparent that the entire metal anode may be submerged in the bath without subjecting the carbon plate to the action thereof. portion may be readily slippedl on and off the carbon plate or core, the lnsulating material is preferably embedded therein, but might be removable.

combination with a core provided at its lower end with an enlarged portion, of a metal portion constructed to fit onto and surround said core, said metal portion being supported by said enlarged portion of said core and insulating material covering the exposed portions of sald core, substantially as described.
5. In a device, of the 4class described, the -combination with a core provided at its lower end With an enlarged portion, of a metal portion constructed to fit onto and surround said core, said metal portion being tapered upwardly, the thickened end thereof resting upon the enlarged portion of said core, sub- -stantially'as described. y
