Description

useful Improvements tion is to provide the iron and towhich or rann rnoiv.
To all whom it mayconcern:
Be it known that l, JAMES H. citizen of the United States, residing at New York, in the county of New York andState of New York, have invented certain new and in Galvanized lfron, (Case 26,) of which the following is a specification. a
The. principal object of the present invengalvanized iron possessed of improved endurance when exposed unpainted to the-weather, and capable of re- Gravnnn, a
'tainlng paint without peeling under those conditlons. To this and other ends, hereinafter set forth, the invention, generally stated, comprises a galvanized iron provided with a superficial coating of zinc phosphate which resists the action of the weather upon paint is strongly adherent. I
A coating of zinc phosphate may be pro duced upon articles of galvanized iron by boiling them for about .two hours in, for example, a half of one per cent. solution of phosphoric acid in water. en this is done the co'atin of zinc phosphate contains no water solu 1e salts 'of zinc and therefore is well adapted to withstand moisture even meet h application filed March aa, ram. Serial No. aaaaii.
though unpainted, but the invention is not limited to the described process of produc ing a coating substantially of zinc phosphate .upen galvanized iron.
Galvanized iron provided with a superficial coating of zinc phosphate may be exposed to the weather and to atmospheric conditions without rusting or otherwise deteriorating for a much longer time than galvanized iron without such a coating, and the coating of zinc phosphate, being absorbent or somewhat porous,strongly retains paint and avoids its peeling ofl. The superficial coat of zinc phosphate is formed from the zinc with which iron is coatedin the galvan izing operation and therefore is strongly adherent.
at I claim is:
r 1. An improved article of manufacture consisting of galvanized-iron rovided with a superficial coating of zinc p osphate, substantially as described.
A? mproved article of manufacture consisting of galvanized iron provided i v a superficial coating of zinc phosphate and having'a coat of paint adherent to the zinc phosphate, substantially as described.
