Description

UNITED STATES PATENT OFFICE.
JOSEPH MEYER, OF HOBOKEN, NEW JERSEY, ASSIGNOR 0F ONE-FOURTH TO WILLIAM E. DAVID AND ONE-FOURTH TO RUDOLPH EI-IART, BOTH OF HOBOKEN, NEW
JERSEY.
COMPOUND FOR HARDENING STEEL.
No Drawing.
T 0 all whom it may concern Be it known that I, Josnrrr MEYER, a citizen of Switzerland, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Compounds for Hardening Steel, of which the following is a specification.
This invention relates to compounds for hardening steel and it consists in the novel congregation and commingling of the ele ments hereinafter described and approximately in the proportions set forth.
An object of the invention is to provide a compound adapted when metal is heated to a required degree and plunged into the same to effect extreme hardening of the metal.
The following is a list of the components of the compound which are brought together approximately in the proportions named. The base of the compound is fifteen gallons, liquid measure, of distilled water H O, to which is added one and one half gallons, liquid measure, of raw linseed oil. To this mixture is added twenty-six pounds, weight, of salt Na-Cl, seventeen and one half, fluid, ounces of muriatic acid HCl, seven-tenths of an ounce, weight, of alum salt and seventeen and one-half, fluid, ounces of sal-ammoniac NHfil. These ingredients when compounded are thoroughly mixed and permitted to stand ready for use. WVhile the compound is standing the linseed oil rises to the surface and forms an oily skim or coating at the surface of the compound. The alum salt precipitates and carries to the bottom of the vessel containing the compound any solid matter or foreign substance which may be carried in the Specification of Letters Patent.

Serial No. 3,155.
water or which may be introduced into the compound with any of the other ingredients. 7
The volume of water contained in the compound efiiciently dissolves the salt and re duces the acid to a proper state of solution to produce by arranging the molecules in the metal immersed in the compound a condition of hardness without damage or injury to the metal.
hen the metal is heated to a proper degree it is plunged into the compound and passes first through the thin skim of oil at the surface of the compound. A film of oil adheres to the metal and penetrates into the same and when the metal passes down into the water the ingredients held in solution and in suspension in the water enter into the pores of the metal whereby the grain thereof is arranged to produce extreme hardening in the same. Therefore it will be seen that a compound of simple nature is provided and that the same may be used to advantage for producing extreme hardness in metal such for instance as steel.
Having described the invention what is Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington. I). C.
