I SPECIFICATION formingpart'of Letters Patent No. 519,595, dated May 8, 1894.
Application filed JunoZO, I893- $eria1 No. 478.248. (No model.)
- To all whom) it-may concern:
Be it known that I,- HERMANN THOFEHRN, a
subject of the Emperor of Germany, anda resident of Paris, France, have invented certain new and usefullmprovements in Electra plating; and I do hereby declare that the following is a full, clear, and exact description of the invention,'which will enable others skilled in the art to which it appertains to tures which will be hereinafter describedand make and use the same. 1 1
This invention has for itsobject to provide a new and improved-apparatus whereby electrolytic depositions of copper or other metal can be obtained, in .such manner that the metal deposited possesses great fineness and.
perfect homogeneity.
To accomplish this object my invention con-- sists essentially in the combination of an electrolytic bath, of an anode and cathode,'and a reciprocating spraying pipe for showering the electrolyte upon the cathode. v
The invention also consists of other feaclaimed, reference being made to the accompanying drawing, inwhich the figure i's a Vertical sectional View of an electrolytic bath enihodying my invention.
In order to enable those skilled in the art to make and use my inventio'n,-I will now describe the same in detail, referring to the drawing, where I have illustrated the working of the apparatus in connection with a cylinder which is to be plated with electrolytic metal. The cylinder is mounted on gudgeons 2 and is rotated by any suitable mechanism, such for example as a belt connection 4 with a shaft 3 rotated by any suitable motor. The anodes 7 are arranged in an inclined position near the bottom of the-tank in which the cylinder is mounted to rotate, and these anodes are coupled up and traverse the bath so as-to deposit the metal upon the cathode 1 and leave placed at a higher level, wherein the liquid is purified, that is to say, freed from matters which are injurious to the quality of the deposit. From the reservoir 10 the liquid passes into a neighboring reservoir 11, wherein it is restored to its standard strength, and from which it falls so as'to shower the cathode, under a pressure regulated according to the elevation of the feed tank 11. The showering is produced by a spraying pipe 12, receivvolving surfaces the pipe may conform to such V surfaces. The discharge pipe 12 is perforated with small holes arranged very close, together,
so that all parts of the metallic deposit willbe acted upon'bythe liquid jets falling under a pressure which may beeasily regulated. A
, longitudinal slot extending all along the discharge pipe would answer the purpose equally well... I
By the means described I obtain a perfectly homogeneous metallic deposit on the surface of thecathode, giving to the metal the qualities-required by thetr'ade. I
The electrolyte is maintained at a uniform level, and above the point of submergence of the, cathode, by means of the-supply pipe 12",
v the levelof the fluid being preserved by means of the overflow pipe 17, which discharges into the tank 18, the latter being connected by a suitable pipe with the pump 9 and the pump being connected with the tank 10. y
l The to-and-fro movement of the spray-pipe 12 is effected in the following manner: The ends of said-pipe are prolonged sufficiently to enable them to be carried through the sides or walls of the tank, which thus furnish a bymeans of a flexible section of pipe. Upon one of the outwardly projecting ends of the spray-pipe 12 is mounted a finger 12', which i lies in a cam-race formed in a disk 15, which is carriedby a shaft 15, driven by a belt 16, from a driving-pulley 16 carried by the powershaft 3.] his evident that'a number of spraying-pipes 12 may be simultaneously operated corrosion of the fluid, save at points of contact for the anodes, by an insulated coating of caoutchouc or gutta-percha. The rods 20,
justably fulcrumed in said support, a conical frustum operating said levers, a cam-shaftdriven from the power-shat t, and earns simultaneously operated by said cam-shaft to raise the can-support and depress the conical frustum, substantially as specified.
4. In a mechanism for seaming sheet metal cans, the combination of a seaming head arranged to be held stationary in use with a series of seaming dies borne on adjusting levers provided with adjustable fulcrums, and wedge mechanism to move them when in use.
5. The combination of the seaminghead29, arranged to be held stationary in use with a JOHN A. STEW'ARD.
