Description

UNITED ST TES PATENT OFFICE.
JOSEPH T. COMMOSS, OF NEW YORK, N. Y.
IMPROVEMENT IN'PROCESSES 0F PREPARING METAL SURFACES FOR PRINTING UPON.
Specification forming part of Letters Patent No. 184,759, dated November 28, 1876; application filed October 30, 1876.
dies, and otherwise manipulated withoutcrack ing, chipping, or otherwise injuring said surface.
The invention consists in the mode of preparing metal plates for direct printing, by means of pale boiled oil, Benguela varnish, turpentine, white lead, magnesia, and soapstone, in substantially the manner hereinafter fullyset forth and described.
In preparing the plates, I use a composition formed by mixing nine pints of pale boiled oil, six pints of Benguela varnish, and one pint of turpentine, with sixteen pounds of white lead ground in oil.
These ingredients are mixed at a temperature of 125 Fahrenheit. Should the mixture become thick, I reduce it to the proper consistency by adding pa le boiled oil and Benguela varnish in equal quantities.
While the mixture is warm it is strained through a set of four or more graduated wire screens, the latter ones being very fine, and
- is then ready to be applied to the metal plates.
The mixture is applied with a flat black pitch brush, and the plates, when coated, are arranged in racks, and placed in an oven heated to 125 Fahrenheit, and are kept at that temperature for forty-eight hours. The plates are then taken out and powdered with a mixture of two parts of powdered magnesia and one part of powdered soapstone, and are then ready to be printed upon.
The printing is done by the usual machinery, and in the usual way, except that a heavier pressure is required than when printing upon paper. After printing, they are again powdered with the magnesia and soapstone.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The method of preparing metal plates for direct printing, by means of pale boiled oil, Benguela varnish, turpentine, white lead, magnesia, and soapstone, in about the proportions and in the manner substantially as herein set forth and described.
JOSEPH T. OOMMOSS.
