Letters Patent No. 95,990, dated October 19, 1869.
IMPROVE!) METALLIC ROOFING.
The Schedule referred to in these'L-etters Patent and making` part of the lame.
To all whom it may conce/rn.-
Be itknown that I, JOB B. Gnou/Lm', of Middletown, in the county of Midqiesex, and State of .Gonnecticut, have invented a new Improvement in Enamelled Corrugated Roong and I do hereby declare the following, when taken iu Connection with the accompanying drawings, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, 1n-
Figure l, a top view of a piece of roong, and in Figure 2, a transverse section of the same.
This invention'relates to an improvement in metal roofing, and is especially adapted -to that commonly known as corrugated roofing, the object being to avoid the use of pain t ating, which wears awaysoastor Y" d The invent-ion consists in coating themetal, uponone or both sides, with loorc'elaicl'ay,` 6r other vitreous material, while in a plastmstate, then', by heat `or otherwise, hardening the coating..
To enable others skilled in the art to make and my invent-ion, I will fully describe the same, illustrated in the accompanying drawings.
By preference I form the metal in plates,`as seen in iig. l, the several plates corresponding in size, and corrugated as seen in section, iig. 2, eachy plate being perforated, as a means of securing to the roof'. l
'Then I coat upon the upper side, (and, by prefer ence, both sides,)by spreading thereon a coating of porcelain-clay, or other vitreous substance, while in-a plastic state, and then harden the Coating by subjecting it to the heat or a drying-process, aud when hardened, the roofing is ready for use, to be applied in the usual man ner of similar metal roofing.
This coating is not affected by the atmosphere, and. is notV in the slightest degree worn away, as other coating, or paint. i Having fully described my invention,
What I claim as new and useful, and desire to secure by Letters Patent, is
As a new article of manufacture, metallic roofing,4
coatedv u'pon one or both sides, with porcelain, or
other vitreous material, snbstantiallyas set forth.
JOB B. CROWLEY.
