EBENEZER G. POMEROY, OF PITTSBURGH, PENNSYLVANIA.

MANUAGTURE oF SHEET-IRON.

Specific'sation of Letters Patent No. 10,482, dated January 31, 18,54.

To all whom t may concern.'

Be it known that I, EBENEZER G. POM- ERoY, of the city of Pittsburgh, county of Allegheny, Commonwealth of Pennsylvania, have invented and discovered a new and useful improvement in the mode of protecting iron from oxidation while I beautify its surface by incorporating with such surface by mechanical force solid carbonaceous matter; and I do hereby declare that the following is a true and perfect description of my process for accomplishing this result.

I make a paint by grinding plumbago, pulverized charcoal and the black soot formed by the'burning of bituminous coal, or other bituminous matter, along with ivory, or bone, or lamp black, either with Water, weak spirits, vinegar, or any acetous preparation, until the paint is very fine, and t to be applied, which is done with a soft brush to the surface of the iron which has been previously cleansed by any of the modes in common use so as to leave a clean surface of iron. When the surface is completely covered the iron is ready for t-he nextl process, which consists in passing it between rolls substantially -as done in reducing common sheet iron, the result being such a combination of the carbonaceo-us matter with the surface of the iron as to form a permanent coating thereupon which will maintain its place under `any of the processes of manufacture into articles for use, to which sheet iron is ordinarily subjected.

I have found the best and most reliable results to be obtained from the use of'fplum-f bago, pulverized charcoal, bone black, and soot obtained from burning b1-k tuminous coal or other bituminousv matter, in equal proportions as to volume or bulk, ground together in the medium of common vinegar, to the consistency of white lead when prepared for second coating by painters, and that it is also better to heat the iron after it has been painted before rolling it. But I do not confine myself `to the use of the articles here -named in the combination here suggested. Good results may be obtained by leaving out some of the articles mentioned by me.

`The iron to .which I have applied my improvement has been sheet iron and in regard to this article I conceive it to be most useful, but it may be applied to any iron to which the proper mechanical force may be applied to produce the necessary combination.

The coating aforesaid is susceptible of a i high degree of polish, which, when desired 'I produce by means of a planishing roll or rolls as follows, viz. After preparing, coating and-rolling the iron as before stated, it is then planished by placing the sheets one at a time, upon a cast or wrought iron table, or other hard substance, made perfectly smooth von the surface, and resting on a firm movable foundatio11`,'and of suflicient size to admit of a sheet of the dimensions required, to lay on its surface, as seen in that. part of the drawing accompanying this specification, `marked Plate. This plate is movable similar to the bed plate of a slating'niachine, and is fed in a manner similar to the feeding apparatus of a planing machine, or saw mill. The weightfI/V is supported on one or more rolls of small dimensions and is drawn to andfro by a connecting rod attached `to any-machinery in mot-ion, and is kept parallel and prevented from upsetting by the guides and cross heads G,l G. The weight W is recessed at the to (marked R) for the purpose of adding greater weight, and which it is intended should t into the recess to prevent slipping.

I have found it most advisable to cleanse the iron and Iapply 'the coating when the sheet yhas been extended to about one half the length intended. o I do not claim the use of the above materials'in combination as a paint or composition that maybe forced into the surface of iron. But believing that I am the first person who has ever incorporated solid carbonaceous matter with the surface of iron by mechanical force.

I/Vhat `I do claim as my invention and discovery and desire to secure by Letters Patent is- The incorporating, substantially as herein described, solid carbonaceous matterwith the surface of iron so as to protect it from oxidation and beautify it at the same time.
