1931. s. N. WILLIAMS ARTICLE OF MANUFACTURE Filed Aug. 11, 1930 s/ EZM 4 /Zz ATEYS Patented Nov. 3, 1931 UNITED STATES PATENT OFFICE GEORGE N. WILLIAMS, OF KOKOMO, INDIANA, ASSIGNOR TO CONTINENTAL STEEL COR- PORATION, OF KOKOMO, INDIANA A CORPORATION OF INDIANA ARTICLE OF MANUFACTURE Application filed August 11, 1930. Serial No. 474,618.
This invention has reference to an iron or steel article which has a protective coating preferably of. zinc spelter and such coating cement-coated.
The invention. furthermore, relates to an article ofv manufacture as, for example, a nail or the like. provided with an exterior coating of a material. preferably non-metallic, which has a low melting point, as, for example,
cement-coating, a substance or compositlon which is sensitive to heat and which will become softened by the heat of friction occasioned by driving the nail, only to become set again when the nail hasbeen driven home, when the cement-coating adheres not only to the nail but also to the surrounding fiber of the material into which the nail has been driven. and holds the nail practically cemented in place: and having a metallic protective coating between the body of thenail and said exterior coating.
coating functioning to set the article.
Cement-coating as herein used is well known to those skilled in the art as relating to a substance or composition including agumniy-like-constituent, such as gum orresin.
I am awarethat to coat nails and like articles with zinc spelter. per se, is not new and I am also aware that to coat-nails and like arti- In this instance, I combine the qualities of a protective coating on the iron or steel article with an exterior coating of a substance or composition which tends to set or cement the article in place; the zinc spelter protecting the article against corrosion and the cementhave found that merely cement-coating an article, as for example a nail, does not offer that degree of protection against corrosion as is offered by zinc spelter due .to the fact that when the nail is driven and the cementcoating is'softened, there is a tendency to expose surface portions of the. nail for the colnail and then surfacing such coating with a cement-coating, I obtain, first, an article which is fully protected against corrosion and coating has a better and more effective ad-v hesion of the zinc spelter than it does to the iron or steel article itself.
That the invention may be more fully understood, reference is had to the accompanying drawing illustrating a preferred embodiment of the invention, in which:
The figure shows an elevation of a nail partly broken away to disclose the zinc spelter coating on the body of the nail and such coating covered with cement-coating.
In the drawing the nail is shown having th shank 1 and provided with the usual head 2 and the driving point 3. The surface of the complete nail is shown coated preferably with a zinc spelter coating 4 applied in any preferred or usual manner and such zinc spelter coating covered or coated with a cement-coating 5. i
As pointed out, the zinc spelter is a coating which will protect the body of the nail or similar article against corrosion and rust attack and said zinc spelter covered or coated with a cement-coating which has properties sensitive to heat so that when applied to a nail and the nail driven. the cement-coating becomes softened by the heat of friction occasioned by driving the nail, only to become set again when the nail has been driven home; furthermore, as pointed out, the cementcoating has a better'adherence or bonding action when applied to the zinc spelter coating than when applied to the iron or steel body and if and in the event. due to the action of heat resulting from friction the'cementcoating opens or spreads sufficient tov allow moisture to attack the article itself, such is prevented by the zinc spelter covering the article and interposed between the article and the cement-coating.
What I claim is:
As a new article of manufacture, a nail having a zinc spelter coating extending throughout substantially its entire surface- Leaeem and a cement coating including a gummy-like constituent completely enveloping the first named coating and having an aflinity therefor, and further having a lower melting point so as to be softened by the heat resultant from friction upon driving the nail into position so as to effect adherence of the cement coating to the material into which the nail is driven. In witness whereof, I have hereunto set my hand this 8th day of August. 1930. GEORGE N. WILLIAMS.
