To all whom tmay concern:
Be it 'known that wc, l'ViLLL-Lw G. Gnnv -and lVILLLnr GRIFFITH, of Pittsburg, inthe county of Allegheny and State of Pennsylvania, have invented a certain new and useful lmln'ovement in Methods of Uniting Metals, of which the following,r is a full, clear, and exact description, reference beingr had to the accompanying drawings, which form part of this specification.
Our invention relates to a method of uniting met-als of ditterent kinds, such as iron and steel, with copper, brass, bronze, almninum or other metals or alloy; and it consists` generally stated, in.tirst subjecting the harder metal to a cleaning and other preparatory treatment., then appli-'imaT in molten form the softer metal to be united thereto.
7e will now describe our invention, refer ring to the accompanying drawmgs, so that` others skilled in the art to which it appertains may understand and practice the same. While in the accompanymjsr drawings we have shown ourinvention as applied to the preparation of ingots, billets or bars,` we do not desire to limit ourselves to any particular shape. describing our invention, we will hereinafter refer to the iron or steel bar or other shape as the harder" hodv of metal.
Figure 1 is a vertical sectional view showing the body of harder metal placed in a suitable mold preparatory to receiving;r the softer metal in molten form: l `i, r.f2 a sectional viewof a billet or bar preiiared by our improved method; Fig. 3 is a vertical sectional view correspondingl with Fig. l, hutshowing,r the preparation ot' a shape. adapted to receive a core of softer metal: and Fig. -'l is a sectional view through Such a structure, showingr the core ot' softer metal.
ln carrying out our invention. the body ot' harder metal L is first. subjected to a cleaning.,r or.preparatory bath for the removal of the .scale and oxid from the sur-- face or surfaces to which the softer metal is to be united. 'l'his cleaning hath may he the ordinary acid solution used for 'this purpose. After this treatment, the body 2 may be given a coat; of alkali solution, such as chromate potassium or chromate sodium, so as to prevent ready oxidation ot After For convenience, howeveizdn' the body 2 of harder metal has received the above treatment, it is placed in a solution of salt of metal, sulfuric acid and alum. The particular"metallic salt unich we prefer to employ is sulfate of copper. This solution is preferably proportioned as follows, although it may be proportionately varied without. departingifrom our invention and we do not ,therefore desire to linut ourselves to the specific amounts stated: l lbs., sulfate of copper, 2 ounces sulfuric acid, 2 ounces-of alum, to l gallon of 'ater. The body is allowed to remain in this solution until it has received a deposit of copper.
After being given the above preparatoryV treatment the body is placed in a suitable mold preparatory to receiving the body of softer metal to be applied in molten form to the treated surface or surfaces of the said shape of harder metal Q. In F ig. l of the drawings, we have indicated such a. mold by the numeral 3, having the cavity 4 wherein is placed thevbar or billet Q, adapted to receive and be enveloped or inclosed by the molten n'ietal 5, which is adapted to be introduced at the mouth 6 of the mold; the size of the cavity being dependent, upon the ultimate thickness to be given the coating of softer metal 5 after the prepared shape has been rolled or reshaped as desired.
ln Figs. 3 and 4 we show the body of harder metal 2 as havingr the cavity 7 which, after receiving the above mentioned preparatory treatment. is adapted to receive in molten forni the core of softer metal 8; the suitable mold 3, similar to the mold shown in Fig. l, being provided for the application ot' the molten metal to the cavity of the harder body of metal. i 'l`he advantages of our invention will be appwciated by those skilled in the art.' By addingthe alum to the solution of metallic the harder metal in an even, com Jact, homogeneous manner. lt. also facilitates this operation.
Having thus described our invention,
ters Patent is:
1. The herein-described method of unit ing,r metals, such as iron or steel with copper, brass, bronze, aluminum, or other metal or salt, the copper is caused to be deposited on 'what we claim and desire to secure by Let- 105 alloy, which consists in first. cleaning the harder metal, subjecting it to a solution of metallic salt and alum, and then a molten form the body of softer metal.
2. The herein-described method of unit- 5 ing metals such as iron or steel Witl brass, bronze, aluminum or other alloy, which consists in first clea harder metal, applying a coating solution, subject1 ng it to a solution of metalset our hands. 1 copper, metal or ning the Witnesses of alkali .M. ARTHUR KELLER, I BIARY A. BARTH.
and then applying' in 10 hereunto VILLIAM G. GREY. WILLIAM GRIFFITH.
