ELECTROLYTIC CATHODE DIAPHRAGM STRUCTURE Original Filed May 7, 1928 5 Sheets-Sheet 5 gwuwntoa 6 or may! a greater area of active surface, owing to their corrugation and exposed sides.

Fig. 8 shows a modified form of tank 7 adapted for applying diaphragms by this 5 method to an ordinary flat cathode plate.

My invention is not limited, however, to the particular embodiments illustrated in the drawings, but comprises broadly a method of making electrolytic cathode -diaphragm structures wherein a fibrous material, such as asbestos fiber, is deposited on the active perforated surface of a cathode structure, by bringing a suspension of the fibrous material in a liquid, such as water, into contact with the active perforated surface of the cathode, and by the application of differential pressure forcing the liquid of the suspension through the perforations of the active surface; particularly to such a method wherein the fibrous material is-maintained in suspension by means of jets of water, said jets being preferably directed to cause agitation rather than circulation and particularly also to such a method in which top and bottom jets of water are so balanced as to give a uniform coating of the fibrous material.

ture, com rising a plurality of cupped hollow mem bers mounted in parallel alignment and communicating at their ends with a common header for receiving the cathodic products of decomposition, said members being perforate over their entire surface and covered by a substantially uniform seamless layer of fibrous material.

6. An electrolytic cathode-diaphragm structure, comprising a plurality of cupped elongated and flattened hollow members mounted in parallel alignment and communicating at their ends with a common header for receiving the cathodic products of decomposition, said members being perforate over their entire surface and covered by a substantially uniform seamless layer of fibrous material.

In testimony whereof, I afiix my signature.

KENNETH E. STUART.

My invention also comprises apparatus suitable for carrying the above described method of making electrolytic cathode-diaphragm structures into effect; and the electrolytic cathode-diaphragm structures thus produced.

This application is a division of my application Serial No. 275,860, filed May 7 1928, and is particularly directed to the novel electrolytic cathode-diaphragm structures of the invention.

I claim 1. An electrolytic cathode-diaphragm structure comprising an electrolytic cathode having a warped or non-developable active perforated surface, said surface being covered by a substantially uniform seamless layer of asbestos fiber.

2. An electrolytic cathode-diaphragm structure comprising an electrolytic cathode having a warped or non-developable active surface consisting of wire cloth suitably sup ported in the desired warped shape, said wire cloth being covered by a substantially uniform seamless layer of asbestos fiber.

3. An electrolytic cathode-diaphragm structure comprising an electrolytic cathode havmg a warped or non-developableactive perforated surface. said surface being covered by a substantially uniform seamless layer of fibrous material.

4. An electrolytic cathode-diaphragm structure comprising an electrolytic cathode having a warped or non-developable active surface consisting of wire cloth suitably supported in the desired warped shape, said wire cloth being covered by a substantially uniform seamless layer of fibrous material.

5. An electrolytic cathode-diaphragm struc- June 7, 1932. K. E. STUART ELECTROLYTIC CELL Filed April 25, 1930 MN MN 3 .3
