Description
UNITED STATES PATEN 1 ()FFICE.
W. DEWEES WOOD, OF MGKEESPORT, PENNSYLVANIA.
IMPROVEMENT IN MANUFACTURING SHEET-IRON.
Specification forming part of Letters Patent N0.13'7,5 $5, dated April 8, 1873; application filed March 17, 1873.
To all whom it may concern:
Be it known that I, W. Dnwnns WOOD, of McKeesport, in the cou ty of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Mode of Finishing SheetIron; and I do hereby declare the following to be a full, clear, and exact de scription thereof.
My invention consists in the mode of finish in g ShQGiJ-iIOD by, first, securing a non-oxidizable surface, in the manner hereinafter set forth; second, rolling and annealing; and, third, hammering in packs while cold.
To enable others skilled in the art to make and use my invention I will proceed to describe the same.
The iron, after bein gbroken down into sheets by rolling, is cleaned of its scale by acid and alkaline baths, and Washed with hot water in the manner usually practiced in the art; or the scale may be removed by other suitable process. The sheets are then immediately placed in a hot-air oven" and thoroughly dried, and, While still warm and free from rust, they are plunged into a bath of graphite and oil, or an equivalent mixture of suitable consistency for coating the sheets therewith. The sheets are then rolled in packs of three or more at a good rollingheat. After they are trimmed and annealed I arrange them in packs of, say, from ten to one hundred, more or less, and, while cold, subject such packs to the operation of hammering over their entire surface. With a system of hammers operating at the rate of, say, twenty to forty blows per minute, a medium-sized pack can be ordinarily hammered sufficiently in about ten minutes, more or less, so as to impart to the sheets a polished surface superior to that of the best Russia sheetiron.
The graphite and oil any be applied separately, if so desired.
What I claim as my invention, and desire to secure by Letters Patent, is-
In the process of finishing sheet-iron, the combination of the followin g steps: First, coating the sheets separately with a graphite-andoil coating; second, rolling and annealing; and, third, hammering in packs while cold, substantially as set forth.
In testimony whereofI, the said IV. DEWEES WOOD, have hereunto set my hand.
W. DEWEES WOOD. Witnesses:
A. S. NIoHoLsoN, G. H. OHRISTY.
