@elle out the so-called cylindrical type are largely used Athe electrolysis ot salt solullll tion to produce soda and chlorin. Cell units el this type have a round or rectangular cathode et punched orperforated steel; this cathode carrying a diaphragm, usually asbestos rthe cathode yis mounted Within a steel casing delining a cathode chamber, While thev anode chamber containing the anolyte, is Within and dehned by the dia phragm and cathode. At the top, the cathode compartment is closed by an annular top member'resting on and supported by a Harige ol the casing. 'llheanode rods depend from and are carried by a cover resting on this top member. 'lhus the Weight ol thev anode, cathode and anolyte is carried on the top llange ot 'the casing. This has certain mechanical and operating disadvantages.
lt is the Lpurpose of the present invention to simplily and cheapen this construction and produce a stronger and mechanically better structure. Certain advantages in operation are also obtained. ln the present invention ll employ the usual outer casing and contained shell ol perforated sheet'metalacting as cathode and carrying a diaphragm, the shell and casing dehning a cathode chamber betvveen them and the anode chamber being vvithin the diaphragml cathode shell. But instead of suspending the interior parts or lltl lill the casing, the Weight of these elements rests the cell from an annular flange on the top of on the bottom of the casin In practice I form a bottom for the cathogle shell by a base member of concrete While I provide ythe top ofthe casing with a two-part cover member, also oi` concrete or other suitable insulating material fitting inside the top edges of thev casing. The cover member comprises both a cathode ring and an anode ring and is provided With a recessed llange extending nearly to the casing, with a plastic mastic composition Within the recess making a as tight vjunction with the casing. The Weig t ofthe anode and the cover member instead of rest-l ing upon the top of the outer casing is supported by the cathode shell whose concrete bottom is upon the bottom of the cell. The arrangement Vof the cell elements as above outlined constitutes asimplied construction lowering the expense of installation, lessening the maintenance requirements and improving the processof operation.

As lshown element l is a tan'lrlilre casing of sheet metah open at the top and havin'ga bottom 2. This casing may vbe round or rectangular but is shown as circular. Withf V.inthe casing is a base plate 3 Which is best made of concrete material and carries a vertical shell 4 of perforated or punched metal. Steel is ordinarily used. The shell carries vthe usual asbestos diaphragm 5. This shell in operation forms the cathode. v`At its top it carries annular top lmembery 6 of special concrete.v Resting, on this annular member is the top 'l' of the anode chamber, this top serving to carry 'depending anodes 8 foi graphite or other usual material. Anode carrier? may also be of concrete. It is'pro-' vided with adomed top. Through this dome enters chlorin outletpipe 9. The bottom of the annulus 6 is recessed at 10 to take the top of the diaphragm. Peripherally; element 6 is provided with a laterally extending recessed flange llgadapted tov seat against and` make a joint with casing 1 by'means of a mastic'composition 14.
