FRANK JOSEPH BRIGGS, .OF lEVERETT,V MASSACHUSETTS.
SPECIFICATION forming part of Letters Patent No. 776,490, dated December 6, 1904.
Application tiled September 19, 1903. Serial No. 173,812. (No model.)
To all whom, it may concern;
Beit known that I, FRANK JOSEPH Bnises, a citizen oi' the United States, residing in Everett, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Electrodes, of which the following is a specification.
This invention relates particularly to electrodes such as are employed in an electrolytic apparatus of the general character shown and described in Letters Patent of the United States numbered 729,889 and dated May 12, 1903.
In electrodes as ordinarily constructed there are leaden connections not only between the carbons, but between the electrode and the electrical connections. In order to renew the electrical connections, the lead (which is very heavy) must be removed and run againy into molds and the carbons molded in. Moreover, the lead is injuriously affected by the vdecomposition of the electrolyte, with the result that the connections with the carbons are broken.
My invention has for its object to obviate these diihculties and to produce by mechanical means an electrode adapted for use in an electrolytic apparatus for the decompositions of the alkaline chlorids in which it is possible to claim electrical connection which will assure high eiiiciency and in which the carbons are combined eectively so that they are used as one electrode.
The nature of the invention is fully described below and illustrated in the accompanying drawings, in Which- Figure 1 is a perspective View of an electrode embodying my invention with the top removed. Fig. 2 is an elevation of my improved electrode with the top in position. Fig. 3 is a horizontal section taken on line 3 3, Fig. 2. Fig. 4. is a vertical section taken on line 4. 4, Fig. 3. Fig. 5 is a vertical section taken on line 5, Fig. 2.
Similar letters of reference indicate correspending parts.
a represents a plurality of carbons or anodes separated from each other by leaden plates said plates being horizontal and near the upper ends of the carbons and being secured into position by pins c. (See Figs. 3 and 4.)
CZ represents an integral clamp made of angle-iron, said clamp surrounding the row oi' carbons and being held horizontally in position thereon near the upper ends oi' the main portions thereor1 by a screw e, which sets against a washer or plate f. By means oi' the horizontal iiange portion y oi' the clamp it can rest on the top oi an electrolytic cell and support the carbons therein. Each of the carbons is provided with an upwardly-extending head /L integral with the carbon, each of said heads being at one side of the center oi' the main portion ot' the carbon and said heads being arranged in pairs, whereby those of 'each pair are set near the farther edges of their carbons in order that they may be separated from each other by a greater space than they would be if they were centrally located. The carbon heads 7L of each pair are connected by a ribbon of copper 7c, whose opposite portions between the tops are drawn together by means of bolts Z, which extend through washers a into threaded copper lugs y). By this means the ribbons can be tightened between the two heads of a pair, and it is principally for the purpose of accommodating these bolts,
Washers, and lugs that the heads are arranged in pairs and the heads ot' each pair are provided with a comparatively large separatingspace. The lugs p extend down from andare integral with a copper top s, which is provided with the electrical connection z5, which leads to an ordinary mercury-cup on the positive pole.
To clean the device in order to keep the electrical connection in order, the screws or bolts lare loosened and the top s is removed. The carbons and the insides of the ribbons /t are then cleaned and the top replaced. W hen, as is usual, there are four electrodes in a cell, the top of one may bc removed and the electrode cleaned while the rest oi the electrodes are ruiming and the cell continues its work.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. In an electrode, carbons or anodesarranged in pairs, and provided with heads 7L; a copper ribbon r wound around and connecting the heads of the two carbons in each pair; a cop- IOO per top s adapted to be electrically connected; Copper lugs p extending down from said top between the heads oll the carbons in each pair on one side of said ribbon; washers n located on the opposite side of the ribbon, and screws or bolts Z extendingthrough said washers and lugs, whereby the two parts of the ribbon may be drawn together and against the copper lugs, for the purpose set forth.
2. In an electrode, oarbons or anodes arranged in pairs and provided with upwardlyeXtending heads L; a Copper top s provided with lugs p extending down between the heads of each pair of cai-bons; a copper rib- FRANK JOSEPH BRIGGS. illitnesses:
