the under surface thereof. The-chambers 12 thus formed extend lengthwise of the top* or cover and'preferably in parallel relationto each other and are open at their lower edges, opening freely into vat or tank 10. In use the lower edges of the chambers 12. dip into 'or are immersed in the liquid electrolyte contained in the tank 10. In practice the various' chambers 12 should be in communi-- cation with each other. In the particular form shown as exemplify/ing my invention,

a duct or passage 14 is provided through the body of the top or cover and forming a communication between said chambers. Suitably suspended through and within the open lower lmouth or edge of each chamber 12 is an electrode sheet or plate 15. A. convenient arrangement for suspending the electrode plates 15 is shown wherein rods 16 extend throughthe top or cover 11 and are welded or -otherwise secured to the upper edges of the electrode plates 15. These rods' not only serve to support the electrode plates but they also serve as circuit terminals for said plates.' Intermediate adjacent chambers 12 and in the space within the re- 'ceptacle outside of said chambers are suitably suspended and supported the coperating electrode plates 17 having similar suspending rods 18 passing through the top or lcover 11. Of course the rods 16, 18 should be efficiently insulated from the top or cover 11 as-indicated at 40, Fig. 1. The electrode arrangement is shown wherein the porousl diaphragms 19 are suspended from the eX- terlor surface of the lower edges of the walls 13 ofchambers 12.

In Fig. 3 a slightly modified arrangement` is shown wherein thetank 10 is divided into two distinct and separate chambers 20, 21 by a wall l22, bent back and forth upon itself into parallel portions, said wall, in accordance with my invention being formed integrally 'with the top or cover for the tank and depending from theunder side thereof downwardly' into the tank and immersed at its lower edge in the electrolyte. The electrodes 23, 24-,a're suspended-between the adjacent folds or parallel portions of the Wall 22 on opposite sides of said wall, that is', respectively, within the chambers 20, 21, said plates being suspended in the manner above described, with reference to the plates 15, 17 of the arrangement shown in Figs. 1 and 2. It will be understood that the electrode plates '15, -17 are connected to terminals of oppositesign in a supply circuit for a current of electricity. Similarly, electrode plates 23, 24 of the arrangement shown in Fig. 3 are connected to terminals of opposite sign'. In the case of the arrangement shown inFigs. 1 and 2, the gas evolved from plates 15 collects in the chambers 12, which are in communication with each other, and from these chambers the collected gas passes offy through any suitable delivery connections such, for instance, as the lantern 27 and thence to asuitable gasometer and service pipes in a' well known manner. In like manner the gas evolved from electrode plates 17 ycollect in the top of the tank 10 in the space outside of said chambers 12 from which said gas is delivered in the ordinary or usual manner, as, for instance, through the vlantern 27 and thence tothe gasfometer, receiving tank or service pipes in the usual way. Similarly in the arrangement shown in Fig. 3 the gas evolved at the surface of electrode plates 23 collect in chamber 21 and is delivered therefrom through pipe connection 28 while the gas evolved at the surface of plates 24 collect in chamber 20 and pass off through connection indicated at 29.

Where the walls 13 or 22 are curved it may be inconvenient to apply orous da:

phragrn 19 to the inner arcs of tie curve of *said walls. In order to overcome this ob-l stacle various eXpedients may be employed as shown, for instance, in the arrangement shown vin Figs. 4 and 5, the curtain 19 may be slitted as indicated at 30 so as to slip edgewise over the lower edge of the wall 13 so that the diaphragm may be applied to the' exterior surface ofthe Wall 13 at the ben-d thereof. This form of connection is also particularly applicable to the construction shown in Fig. 3, asclearly indicated therein. Janother arrangement is shownin Fig.

6, wherein the curtain 19 is made in sections placed respectively on the outside and inside surface ofthe wall 22, for instance, so as to'be applied only to the convexed surface thereof, the adjacent edges of the sections of curtain passing somewhat beyond `each other and secured by clamp bolts and plates indicated at 31 applied thereto,

It will be understood that in the construction shown in Figs. 1 and 2 as many chambers, 12, may be employed for each tank 10 as may be desired, according to the desired capacity or output thereof. While, therefore, I have shown only. two of such chambers, my invention is not to be' limited'or restricted in this respect.

From the foregoing description it will be seen that I provide an exceedingly simple, inexpensive and eiicient electrolytic cell iff metete n l nin enabled to do away with exl and complicated pipe connections and iittings, wherein the eell tank is 11min closed by e top or cover applied thereto, wherein the electrode plates are .maintained in etlioient separation from each other :ind wherein intermingling ot the evolved gases is prevented.
