PRINTING PLATE.
'No. 284,399. Patented Sept. 4, 1883.
UNITED STATES JOHN F. EARHAR'I, OF COLUMBUS, OHIO.
-PRlNTlNG-PLATE.
SPECIFICATION forming part of Letters Patent No. 284,399, dated September 4, 1883. v Application filed January 25, 1883. (No model.)
7 To all whom it may concern.-
other materials.
Be it known that I, JOHN F. EARHART, a citizen of the United States, residing at Columbus, in the countyof Franklin andState of Ohio, have invented certain new and useful Iniprovements in PrintingPlates; and I do hereby declare the following to be a full, clear, and
exact description of the invention, such as will enable others skilled in the art to which it appertains to'make and use the same.
The object of my invention is the production of a hard or elastic plate or roller having formed in its surface unorganized irregular depressions or seams, for the purpose of decorative printing on paper, cloth, leather, and By one process, which I have already made the subject of my application for Letters Patent, I produce a hard, flat, or cylindrical plate having these depressions, without the use of a matrix, by pouring the molten metal directly into a cold casting-box, or into a box first slightly dampened with water, or, af-
ter several castings have been made, by cooling the metal by slowly dripping it into the box.
For printing on hard substances-such as wood, iron, tin, zinc, slate, stone, glass, &c.- I make a soft or elastic plate or rollerby the following process:
First, a matrix or mold is made of the metal plate already described, in the usual way, from papier-mach, wax, or plaster-oftparis, and then a cast of the. matrix is made of rubber, printers roller, composition, or other elastic material. By this manner a facsimile of the indentured surface of the metallicplate is produced on the soft or elastic one. Whenthus completed, either plate is in readiness to be used by putting the same in any ordinary form of press, and then applying the printing-inks of one or more colors in the usual manner; or
on the surfaceare old, and also that casts have been made of sections of wood, by which imiprinted tations of different kinds of wood are on paper; but
What I claim, and desire to secure by Letters Patent, is'
A printing plate or roller made of hard or elastic material, and provided with uuorgan- ,ized and irregular depressions or seams formed in and extending below the surface of the plate in the manner herein set forth, and for the pur- 6o pose of printing on various substances unorganized and irregular masses of colors, sub-' stantially as described.
In testimony whereof I affix my signaturein presence of two witnesses.
JOHN F. EARHART.
