Description
UNITED STATES PATENT OFFICE,
JOHN STAOKHOUSE, OF ALLEGHENY, PENNSYLVANIA.
IMPROVEMENT IN SURFACING SHEET-IRON T0 RESEMBLE RUSSIA IRON.
Specification forming part of Letters Patent No. 152,814., dated Ju y 7, 1874; application filed May 9, 1874.
To all whom it may concern:
Be it known that I, JOHN STACKHOUSE, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Process for Manufacturing Sheet-Iron, of which the followingis a specification:
This invention relates to a new and useful improvement in the manufacture of sheetirou; and consists of the use of a solution of oxalic acid, or other substance, and water or other liquid, during the rolling of the iron, at or previous to the last rolling.
The sheets of ordinary iron of good quality are placed in packs of four sheets, more or less, in a pack, and, previous to heating for the last rolling, (and I do not confine myself strictly to the last rolling,) I immerse thepack in a solution of oxalic acid and water, about one part of the oxalic acid and-about nine parts, by weight, of water being used to form the bath. When the iron is heated, the water, of course, evaporates, leaving a slight film on the surface of each sheet of iron, which is converted into carbonic-acid gas. This gas combines with the iron, and hardens the surface. There are other substances which will have the sameor a similar effect; but, with oxalic acid, carbonic acid is formed without leaving any residuum or foreign matter. The surface of the iron is, consequently, left clean, and takes a high polish when the sheets are rolled, the iron resembling the best quality of Russia sheet-iron.
After the sheets are rolled they are annealed in suitable air-tight vessels, which renders the iron soft and malleable.
The bath may be composed of any other substance that will dissolve in water, and prod uce carbonic acid whenthe water evaporates, and leave no residuum when thus converted. Other liquids than water may be used to dissolve such substances for forming the bath.
Having thus described my invention, ll claim as new and desire to secure by Letters Patentv The within described process for manufacturing sheet-iron to resemble Russia sheetiron, substantially as described.
JOHN STAOKHOUSE.
