PROTECTED METAL ARTICLE.
Application filed March 26, 1921. Serial No. 455,968.
To all whom it may concern:
Be itknown' that I, JAMES Howann YoUNo, a citizen of the United States, residing in Pittsburgh, in the county of Al- 5 leghcny and State of Pennsylvania, have invented an Improvement in Protected Metal Articles, of which the following descrip tion, in connection with the accoi'nlninying drawings, is a specification, like characters on the drawings representing like parts.
This invention relates to a protected metal article of that character in which an article of corrodible metal, such as iron or steel, is protected against corrosion by a layer of 1 asphalt or like bituminous material alone or in conjunction with layers of fibrous material, such as asbestos, wool or other fibrous felts.
Protective metal articles of the character described are ellicient against corrosion as long as the bituminous layer remains intact, but where the bituminous layer is exposed, it is subject to the deleterious action of light, heat, and atmospheric conditions; also to abrasion and other mechanical actions in handling, crating and shipping, and in some cases to injury by adhesion of one protected article to another.
The present invention has for its object to provide a protected metal article of the character described, which possesses all of the advantageous features of the protected articles above referred to, and in addition possesses highly desirable features not possessed by them, among which may be men tioncd high light and heat reflecting properties, which enables the protected article to be effectively used in warm climates as well as in cold climates, which can be given any surface color desired with any drying oil paints. Also the detrimental ell'ccts oi abrasion or other mechanical actions as well as adhesion are avoided. To this end, an iron or steel article, either rigid or flexible and of any shape or form, which is provided with an exposed layer of asphalt, bitumen or like liydrocarbonaccous material is provided with a relatively thin non-corrodiblc metallic layer, sheet or toll, which is adhesively allixed to the C(Jll'OdlblC metal article by the interposed layer 01' hydrocarbonaceous material, and which can be quickly and easily applied, so as to produce the protected metal article at a" minimum cost.
Fig. 1 is a plan View of one form of protected metal article embodying this invention, and
Fig. 2, a section on the line 2-2, Fig. 1.
Referring to the drawing, a represents an article or corrodible metal, such as iron or steel, which may be rigid or flexible and of any form, and which is herein represented as a metal sheet.
The metal article a is provided with a protective layer 7) of asphalt or hydrocarbonaceous material of like character, which may be applied in any suitable manner as by passing the article a. througha bath of melted asphalt b, and While the layer 6 is in a tacky condition, a sheet or foil 0 of nonrclatively corrodible metal is applied to the layer Z) with pressure so as to cause the sheet or foil 0 to be firmly affixed throughout its area to the asphalt layer (2 and to be thus affixed to the metal article a. The sheets or foils 0 may be applied to the opposite surface of the metal sheet and to the side edges thereof so as to effectively seal the asphalt covered corrodible metal sheet in an envelope of relatively non-corrodible metal, which is impervious to light and prevents the action of the light upon the asphalt layer 5. I
The metal sealing layer of non-corrodible metal also prevents the loss of volatile constituents from the bituminous layer 2) and thereby maintains the efiectiveness of the latter as a protective coating for the iron or steel member a.
The non-corrodible metal layer or foil 0 may be made from the non-corrodible metals and selected therefron'i to meet specific conditions. For instance, copper or zinc foils 0 could be used for ordinary conditions, while aluminum could be used for materials to be erected in the tropics where maximum light and heat reflection is desired, and lead foil could be used where resistance to sulphuric acid was desired.
l urtherinore the protected articles Idescribed, would be immune from sticking together, when subjected to high temepratures and pressure it they were piled together.
. The thickness of the foil 0 may have a relatively Wide range within limits, which permit it to be compressed upon the bituminous layer While the latter is at a temperature sufliciently high to insure a permanent bond between the foil 0 and the layer 1).
The non-corrodible metal foil 0 may be painted in any color desired with any the drying oil paints now in use.
Claim: As an 1n1proved article of manufacture, a
of corrmlihle metal, a layer of hituniinuous or like hydrocarhonaccous material coveringsaid COl'lUtlllJlG metal, and a metallic un velope of relatively non-eorrodible me! al l'oil covering the opposite surfaces and siile edges of the corrodible metal article and afiixed thereto by the interposed layer of "hydrocarbonaceous material. I
In testimony whereofl have signed my 21 i name to this specification. protected metal article comprising an article JAMES HOWARD YOUNG.
