PROCESS OF AMALGAMATING STEEL BODIES.
Specification of Letters Patent.
Patented Aug. 1'7, 1920.
llc it linown that l, Cmnmvcn W. Baum, it citizen of the l nited States, residing at Highland Park, in the county of Lake and Hate ol Illinois, have invci'ited a certain new and useful improvement in Processes of liniulgamutiiug Steel Bodies, of which the following: is :1 full, (dear, concise, and exact ilmrriptiom reference being had to the acronuiaoying' droning, forming a part of this s u-l-ification.
'lhis intention relates to a process of :nuulomnuting ste l bodies and is especially U lure rncd with the process for annilgamat: no the inner imilar-cs of mercury cooled valve stems.
The object o? my invention is to simpliiy the method and shorten the time required for amalguirniting the inner surfaces of the hollow stems of mercury cooled valves.
The method by which 1 accomplish this object is more or less diagrammatically illustrated in the accompanying drawing, in which 1 have shown a valve for internal combustion engines in longitudinal section and the IHQHDS which l employ for amalgumating the inner surface of the hollow stern of this valve.
in carrying out my lill the hollow valve stem 1 with a solution of mercuric ("him-id in hydrochloric acid. the proportions being about one quarter pound of llllltlii'ii' illl fll'li to about seven .munds ol' conin'n -rcial hydrochloric acid. I then insert an flno lo 4: in the stem of the valve the said anode being covered by woven fiber material 1. which prevents the anode 2 f om contacting; with the walls of the valve stem but at the some time permits the current to flow from all portions of the anode immersed in the si'ilution, I then connect the cathode of a storage battery 4: of approxinmtely six volts with the anode 2 and the anode oi said storage battery with. the valve, as indicated at :3. il. switch ll may be improved process I provided for closing the circuit. When the switch 6 is closed the interior of the valve stem becomes very quickly amalgamated to the desired degree, and 1 find that it is unnecessary to renew the solution in the valve stem in order to secure sullicicnt amalgamotion.
While I have described my invention in connection with the amalgamation of the inner surface of a hollow valve stem, it will of course be rexhlil understood that my invention can be employed for amalgamating the surfaces of other steel bodies.
Having thus described my invention, what I claim is:
l. The method of amulgzunating the inner surfaces of a hollow steel valve stem or other hollow steel body which consists in mixing mercuric chloriil salt w th hydrochloric acid, in substantially the proportion of one fourt of a pound of the salt to seven pounds of the acid, to form an electrolyte solution, filling the hollow steel body to be amalgamated with said electrolyte, inserting an electrode in said solution in spaced relation to the walls of said steel body and then causing an electric current to flow from said electrode through the electrolyte solution to said steel body.
2. The method of amalganmting the inner surfaces of a hollow steel valve stem or other hollow steel body which consists in mixing a mercuric chlorid Salli il of hydrochloric mid to solution, filling the hollow steel body to he amalgamated with said electrolyte solution. inserting-an electrode into said solution in spaced relation to the walls of said steel body and then causing an electric current to flow from said electrode through the electrolyte solution to said steel body.
In witness whereof I l'iereunto subscribe my name this 24th day of May, 1918.
