Commoss v. Somers
Opinion of the Court
This suit is brought upon patent No. :.84,759, of November 28, 1876, granted to the orator for an “improvement in processes of preparing metal surfaces for printing upon,”-so that ihey may be printed upon direct, and afterwards struck up without injury. The specification describes using a composition of nine pints of pale boiled oil, six of Benguela varnish, and one of turpentine, with !.6 pounds of white lead ground in oil, mixed at 125 deg. Fahrenheit, strained through four or more graduated wire screens, applied to the plates, and keeping them at 125 deg. Fahrenheit 48 hours, when they are powdered with two parts of magnesia and one of soap-stone. The claim is for “the method of preparing metal plates for direct printing by means of pale boiled oil; Benguela varnish, turpentine, white lead, magnesia, and soap-stone in about the proportions and in the manner substantially as herein set forth and described.” This seems to be a pat<nt for this precise method of using this particular composition. The £ nticipations relied upon are not shown to have been by this method, nor substantially like it, and the patent appears to be valid.
No infringement is shown except by a metal box, about which the plaintiff testifies as an expert:
“I am confident that the plate from which this box is made was first coated with an elastic smooth body or composition composed of varnish, toiled oil, and some colored pigment, of such proportions and consistency as to produce a smooth surface; and such composition has floated on the surface of such plate so as to dry without brush-marks. After this composition 1 as been dried, the plate has been printed on in a lithographic press, and then formed into the box.”
