at its'upper edge Within the 'spiral chamber 'of the top or cover and the othersimilarly formed into a spiral and having its upper edges extending into the space between the spiral .convolutionsof the Walls of the vchainber. .I also propose to separate' the `spiral electrode plates with a porous Acurtain or ldiaphragm also' formed into a spiraland supported' upon the walls of thespiral chamber, the electrode plates being suitably suspended withinv the spiral relation -indicated. `I- also employ 'a gas. delivery connection leading from the closed'chamberfor the delivery o'f the evolved gas collected in said chamber, and another delivery connectioncommunicating with the space outside 4of said chamber for the delivery therefrom ofthe gas collected therein from the other electrode plate.` f

In the accompanying drawing referencenu'meral llldesignates a receptacle adapted to contain the4 caustic solution Aor other liquid to be decomposed and which, inthe present instance, is of'cylindricajl contourclosed at the bottom and open at. the top.

.The open top of the receptacleis closed A'by a .cap or cover 1 1. Carried by, or, and preferably, formed integrally -With the cap .orcover 11` upon theunder sidev thereof isa 4spirally arranged chamber 12, that is, the

Walls 13 of the'chamber. 12.are fornied into a s inal, thereby makingthe .chamber 12 l Wit in .said spiral walls a closed chamber their lower. edges areimmersedin the solu-v pending therefrom intothe` receptacle 10, as

` While 'the s ace.14. outside .-of the inclosure 1lb is open. The spiralv Walls 13 of said wal .of the closed 'chamber 12 depend ydoivn- Wardly fromv the top or cover 11 and at tion to be decomposed. Suitably suspended lvvithin the'closed chamber. 12 is' an electrode plate 15', which is formed into a spiral to conform to the spiral'contour-'of said chamber, the upper'edge of said plate extending through the open mouth of 'said chamber and'into said chamber, thesaidplate de- -clearly shown.- Similarly, an electrode plate 16,- similarly. formed into a spiral is a'r rangedwith its Kupper edge to extend into the open space 414 which surrounds the spiral Wall of the closed chamber 12, said plate 16 depending therefrom into the re' ceptacle 1 0, 'as shown. The elect-rode platesv 1.5, 16 may. be supported in ,the relation' above. described -in `any suitable or convenient': manner. I have shown a lsimple arrangementwherein supporting rods 17, 18 extend through the top .11 and are electrically connected and preferably Welded to the upper edges. ofthe plates 15. 16 respectively. Theserods 17, 18 not only serve to support the electrode plates 15, 16 but they also constitute circuit terminals forconnec-v tion to a convenient .'source of current.

In order to etiicientlyseparate the gas 'claim as new an evolved from or adjacent one electrndenplate' orgth' surface thereof from that'evolved thereto. .A convenient arrangement for supporting the porous curtain is to Supl port the same at its upper edge by applying it atwiseagainst one of the walls of the closed chamber 12. In Fig. 5 I have shown a siszple arrangement for supporting the porous curtain 19 by applying thereto a ring 2O arranged in encempassing-relation with respect to and in position to hue' the 'from .or adjacent the surface of the other of 'f -said plates, I employ a suitable ,porous diaphragm or curtain indicated at 19 andapply the same in interposed relation with respect to the elect-rode plates and in spiral relation' exterior surface of the Wall 13 ofthe (ilosed 'chamber -and suitably secured to said Wall,

for instance, by means of a clamping asl 'bahd 21, the upper edge of the4 curtain being clamped betweentlie vrii1g'20 and the wall 13.

- In order to prevent the formation of a shoulder at the lower edge or mouth of the chamber 12 which .might interfere with the passage of the gas into said` chamber, I p refer to .providetlie lower edge of the ring/20 with an off-set portion indicateds'at 22 to' engage over the. lower edge' of the wall 13,v

thereby .bringing thel curtain 19, or the surface thereof toward .parallel relation with the inner surface'of the Wall' 13 and. hence preventing an otherwise objectionable shoul-.

der at the loi'ver` edge of the wall 13.

A delivery pipe. connection 23 delivers from the' closed chamber 12, and 'similarly .1 a deliverey pipe connection 2ftdelivers from the open space 14. *These delivery. connections mayl include the usual lanterns 25 through which the separated gases passing therethrough may be delivered intoconventhence into service pipes in the.' ordinary manner. r .I

From Ythe foregoing description it .will be seen that I provide aconstruction of electro- .ient gasometers orreceiving tanks and.

lytic cell which is exceedingly simple and wherein the tank or receptacle containing theelectrolyte-isclosed against the access'of dirt, clustA or other foreign matter, ivherein izs y face said cover 'or topfhavr @over ortop :therefor .walls upon its 4under arranged .surf to, forin alclpsedchamb'er, electrode'v porous -curtain separating" said -platesand' ,gas delivery. connections' communicating respectively with lsaid chamber 'and said! ex/ terior}-space., y 2.
