UNITED STATES PATENT OFFICE.
HENRY MCCARTY, OF PITTSBURG, PENNSYLVANIA.
IMPROVED METHOD OF HEATING SHEET-IRON WHILE IN THE PROCESS OF MANUFACTURE.
Specification forming part of Letters Patent No. 9,0?5, dated June J9, 1852:
My invention relates toan improvement in the manufacture of thin plates or sheets of ironsuitable for various uses, and imparting to them that beautiful finish and durable gloss and luster heretofore peculiar to the Russia sheet-iron; and in order that my invention and improvemcn t may be fully understood and readily carried into eti'eet I will proceed to explain the means and process pursued by me.
i take sheets of iron prepared in the usual mannerand clean them with mnriatic acid and zinc placed in a leaden pan, the immersion taking place as soon as a lively or active efi'ervescence appears. Then I withdraw the plates and wash them with water to remove the acid, and dry them. The plates thus prepared are ready for the heatingprocess, which is eli'ected by immersing them in melted lead" or other suitable liquitied substance serving '0 exclude the air from the surface of theiron. After the plates have remained in the liquid till they are sufticiently heated they are passed between rollers arranged similar to the rollers ot' a common rolling-mill in order to produce imported Russia sheet-iron. The mottled marks or spots on the surface similar to those generally found on the surface of the abovedered rather rough and uneven by the process of removing the sca-les,-the roll-ingisnecessary to produce a smooth surface and reduce them 'to an even thickness, the rollers acting rather as planishers than as reducers, although the iron mustnecessarily be somewhat reduced in thickness by the rolling operation. Among the other liquefied substances mentioned as substitute for lead is an alloy of lead and tin,
which does not require so high a degree of temperature to melt as zinc.
Having thus'deseribed my improvement in the manufacture of sheet-iron, by which it is made to resemble the imported Russia. sheets iron and to possess that beautiful mottled 'gloss and smooth hard surface, what I claim as new and of my invention, and desire to secure by Letters Patent, is-
Heating the sheets of iron in a bath of hot lead instead of beating them in an oven, by which the surfaces of the sheets are protected from the oxygen in the atmosphere during the heating process preparatory to the rolling op 'eration.
In testimony whereof I have hereunto signed my name before two subscribing witnesses. a smooth glossysurface resembling that of the HENRY M oGABTY. Witnesses:
WM. P. ELLIOT, J. S. SMITH.
