Specification of Letters Patent.

Patented Mar. a, 1919.

Application filed March 8, 1917. Serial N 0. 153,504.

To all whom it may concern:

Be it known that I, GEORGES CHARBON- NEAUX, of- Le Magnou, par Aigre feuille DAunis, Charente-Infrieure, France, have invented'a new and useful Improvement in Electrolytic Cells, iwhich improvement is fully set forth in the following specification.

Graphite anodes are frequently employed for the manufacture of various products by electrolysis and'particularly for the manuw.

facture ofthe oxy en compounds of chlorin from chlorids. ther anodes formed of various alloys such as those having ferrosilicon for their base or cast metallic oxids are also employed.

In all cases the anodes pass into the elecrolyte from the top of the cell, or through holes formed in the lateral walls or in the bottom of the cell.

These arrangements have the following disadvantages:

As a considerable or is embedded in the walls of the cell, it is not utilized, thus uselessly increasing the cost of installation and maintenance.

As the electrodes are in contact both with the electrolyte and with the liberated chlorinand also with its metal conductors ey must, especially when of graphite undergo a suitable treatment to attacked by the current. Moreover, as the electrodes are near together, it is usually difiicult to obtain good joints between them and the cell,

and this is the cause of great annoyance.

This invention relates to a novel arrangement of electrodes designed to overcome these troubles.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a horizontal section of a cell taken on the line AA of Fig. 2, Fig. 2, is a vertical transverse section on the line B- B of Fig.

1, and Fig. 3 is a vertical transverse section showing a modification. a v

The anode plates a andb are formlstl of graphite, metal, a metal alloy or a metallic oxid.

The left hand plates a alternate with the right hand plates 6 and their overlapping ends are pressed together to two terminals 0 i (i made from one of the materials above portion of each anode avoid being mentioned terial.

The terminals 0 of pass through the wall of the cell and conductors e 7' located outside the bath.

The plates are pressed together by a suita le arrangement situated outside the bath for example, by means of two U irons with tightening bolts above and or by means of bolts passing through the anodes themselves and insulated therefrom by glass tubes, paint or some insulating substance as illustrated bya tube B made, of glass, micanite, or any other insulating substance.

The plate 9 9 arranged between the anode plates.

In place of the plates shown in the drawing the electrodes may consist of rods, bars 01' the like. p

The terminals may be of prismatic or other shape; they are'two in number ora multiple of two and are sealed in the wall of the cell by any convenient means.

It is evident that the arrangement alone described although principally devised for the manufacture of th chlorin is' applicable for the manufacture of various electrochemical products obtained by anodic oxidation.

The arrangement of electrodes herein described, has the following advantages:

he anodes do not pass through the walls of the cell, thus causing an important economy in material forming the anodes and a great diminution in the number of joints. As the terminals alone touch the current leads they also alone require a s ecial preparation for protection against the action of the chlorin.

The joints are easy to make.

laims:

1. In an electrolytic cell of the character described, electrodes consisting of alternating right and, left hand plates whose ends overlap, teri'ninal members adapted to pass through the walls of the cell and associated with the overlapping ends of said plates and means for clamping said terminals and below the bath of the cathodes k '71,} are receive current from the e oxygen salts of overlap, terminal members adapted to pass through the Walls of the cell and associated with the overlapping ends of said plates and a clamping bolt passing through said terminals and overlapping ends and a tube for insulating said bolt from said plates and terminal.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
