Isaac n. Levin, or New Yoan, N. Y.
IELECTBODE.
Application led September 24, 1921. Serial No. 503,012.
To all wil-0m t may concern:
Be it known that I, ISAAC H. LEVIN, a citizen of the United States, residing at the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Electrodes, of which the following is a speci-fication, reference being had therein to the accompanying drawings, which form a part thereof.
My invention relates to electrodes, and more particularly to an anode for use in electrolytic cells for the generation of oxygen and hydrogen.
In the operation of electrolytic cells for the generation of oxygen and hydrogen there has always been a certain loss in the eiciency of the cell due to thev resistance of the metal of the anode as well as t0 the resistance of the metal of the terminal bar.
This loss has been due in part to the prac- Y tical necessity for usingthin electrode plates of ferrous material and for using terminal bars of similar material of insuiiicient crosssectional area to secure aminimum voltage loss as a result of resistance inherent thereto.
While resistance of the electrode plate itself may be reduced and a more effective distribution of the current secured by connecting the terminal bar within the perimeter of the electrode, there has'heretofore, to the best of my knowledge, been no effort made to avoid loss of eciency due to excessive resistancein the terminal bar itself. With the above conditions in mind, have devised an electrode, the' terminal bar ofwhich is so constructed as toimpart high conductivity to the bar in its entirety while avoiding electrodecomposition of .the material of the bar, which factor has heretoforeA precluded the use of metal with high conductivity in the terminal bars. t
In an electrode embodying my invention.,
` the terminal bar is so formed as to be in its entirety an electrical conductor, different portions of which, different degrees of conductivity, although the maj or portion thereof has low resistance.
The terminal bar of the electrode embodying my invention maybe readily connected electrically and mechanically with the electrode plate or plates so as to ensure effective electrical contact between the plate and the terminal.
The invention consists primarilyV in an lthe `point of attachment however, have relatively electrode lembodying therein an electrode plate having large surface capacity and a terminal bar mechanically and electrically connected therewith having an electroconductive core of low resistance and an electroconductive protecting sheathing about the core; and in such other novel features of construction and combination of parts as Vare hereinafter set forth and described, and
more particularly pointed out in the claims hereto appended. i
Referring to the drawings,
Fig. 1 is a rear elevation of an electrode showing oneL embodiment of my invention;
Fig. 2 is a side elevation thereof;
Fig. 3 is a plan view thereof;
Fig. 4 is a rear elevation of an electrode ishowing another embodiment of the invenion;
Fig. 5 is a side elevation thereof;
Fig. 6 is a plan. View thereof;
Fig. 7 is a rear elevation of still another embodiment of the invention;
Fig. 8 is a sideviewA thereof; and
Fig. 9 is an enlarged cross-sectional view of the portion of the terminal bar adjacent tothe electrode plate.
Like letters refer to like parts throughout the several views.
I- usual or lany desired construction such as ordinary sheet iron, or steel, with or without a facing of cobalt, nickel, or otherZ material for reducing the tension at the surface of the plate. lSuch plates ordinarily are of comparatively :thin metal of from oneeighth tothree-sixteenth of an inch, the thickness varying with the surface dimensions of the plate orv according to4 the desired conductivity in the plate necessary to secure an effective distribution of the current throughout same with a minimum resistarce in the plate commensurate with the desiredrigidity thereof. 'L
Mechanically and electrically secured to theplate in any desired manner is a terminal bar, the` essential characteristics of which area core of metalhavin'g high con-Y ductivity, such as copper, com letely sul'- rounded' as to the ortlon thereo within the cell, and partic arly that. portion sub- 1,515,348 A v et contact of the terminal bar with the plate a is relatively greater than the cross-sectional area of the terminal bar.
While I have described my invention as being applied to the anode of an' electrolytic cell, it is apparent that al similar construction may though the terminal bar is not subjected to the decomposition to which the terminal bar of the anode is subjected.
If desired, as heretofore practiced by myself, with cells employing plates having very large surface area, -a plurality of terminal bars, as herein described, may be con? nected with each plate and this connection maybe at two or more points between the plate and the terminal bar.
It is not my intention to limit the invention to the precise details ofconstruction shown in the drawings, it being apparent that such may be varied without departing from the spirit and scope of the invention. lHaving described the invention, what I claim as new andy desire to have protected by Letters Patent, is
1. -An electrode embodyingtherein lan electrode plate having large surface capacity and a terminal bar mechanically' and electrically connected therewith having an electroconductive core of low resistance and an electroconductive protecting sheathing about be applied to the cathode, al-y and a terminal bar mechanically 'trically connected therewith at a point withconnected the core, the portion of said bar in electrical connection with the plate having relatively greater contact area than the chess-sectional area of the bar.
4. An electrode embodying therein an electrode plate having large surface capacityA and a terminal bar mechanically and electrically connected therewith having a copper core and a ferrous vsheathing about same,.
the portion of said bar in electrical connection with the plate having relatively greater contact area than the cross-sectional area of the bar.
5. An electrode embodying therein an electrode plate having large surface capacity in the perimeter of the plate, having an electroconductive core of low resistance and and elecan electroconductive protecting sheathing Y about the core.
' 6. An electrode embodying therein an electrode plate having large surface capacity anda terminal bar mechanically and electrically connected therewith at a point'within the perimeter of the plate, ,having a copper core and a ferrous sheathing about same. 7. An electrode embodying thereim an electrode plate and a terminal bar includa block mechanically and electrically with said plate and an extension having an electroconductive core of low resistance and an electroconductive protecting sheathing about the core.
In witness whereof I have hereunto ailixed my signature in the presence of two sub scribing witnesses this 19th day of September, 1921.l
