To all whom it may concern:
Be it known that I, CHARLES J. KIRK, of
New Castle, in the county of Lawrence and State of Pennsylvania, have invented a certain new and useful Improvement in.
the metal to be protected with zinc flue-dust and then depositinga 'metal on the surface produced by. the amalgamation of the zinc flue dust.
Heretofore metals have been coated with zinc, tin,- and other metals by passing the metal .to be coated through a molten bath ofthe metal of which the coating is composed. Metals have also been coated by depositing the zinc or other metal electrolytically and they have also been coated by what is known as the sherardizi'ngprocess I will now describe my Invention so that others skilled in the art may employ the same.
In the practice of my invention I first sherardize the metal to be coated. This may be done by packing the metal to be coated'inwhat is known as zinc flue dust, which contains-about ten per cent. of oxid of zinc, and then placin the metal and the zinc flue dustin a suita le muflie from which the airis excluded and then subjecting it to heat for a suflicient length of time to. cause an amalgamation of the zinc with the metal to be coated. The mufiie is then allowed to cool and the sherardized metalis withdrawn. Or the flue dust may be mixed with water or oils and powdered charcoal to form a liquid or semi-liquid mass of paint or compound'which is then applied-to the surface of the metal to be sherardized either by dipping the metal in a bath of the compound or the same. The metal so painted or coated is then placed in a muflle and subjected to heat the necessary length of time after which the plosion and the metal is withdrawn and allowed to cool. I have-discovered that this sherardized-surface forms a base upon which tin, zinc, or other metal may be deposited by passing the sherardized metal through a molten bath of the metal used to formthe coating, and owing to its peculiar qualities it causes an adhesion or amalgamation of the molten zinc, tin, or other metal far greater than would exist between the original surface of the metal and such coating, so much so that a coating having new and characteristic properties is produced on the surface of the sherardized metal. The second step of my process therefore consists in dipping the sherardized metal in a molten bath of zinc, tin, or other metal in the usual manner employed in galvanizing, tinning and coating metals in a molten bath. As the metal is wlthdrawn from the bath the excess of molten metal may. be wiped off in the usual manner. The metal when so removed from the bath is ready for use or it may be subjected to various polishing and finishing steps well'known in the art.
The advantages of my invention are that as by the sherardizing step an amalgamation of the zinc, and the metal to be coated, takes place, so in the dipping step an amalgamation of the sherardized surface and the metal composing the molten bath takes place, producing a durable,amalgamated surface on the metal to be protected.
Having thus described my invention, what I claim and desire to secure byLetters Patent is:
sisting in sherardizing the metal to form a primarycoating and then dipping. the article so treated in abath of molten metal capable with the primary coating. by painting the surface of the metal with M. ARTHUR KELLEn,
