PRINTING-SURFACE.

SPECIFICATION forming part of Letters Patent No. 337,725, dated March 9,1886.

Application filed August Q5, 1881. Renewed January 14, 1886. Serial No. 188.550.

To all whom z5 may concern:

Be it known that I, AUGUSTUS TEN WIN- KEL, of Detroit,in the county ot' Wayne and State of Michigan, have invented an Improve,- ment in Printing-Surfaces, of which the following is a specication.

My invention consists in a peculiar printingsurface prepared from wire-cloth,as more particularly hereinafter described and claimed.

In the annexed drawings the various figures represent a printing-surface prepared from wire-cloth of different meshes by my improvement.

Irst take a sheet of wire-cloth of any desired pattern and mesh, which I mount in a suitable frame, secure to a dat surface, or embed in any plastic or soft material, and then proceed to prepare one side for printing by abrading or grinding the same with any abrading or grinding material. In the choiceof material for producing the abrasion it is preferable to select such as will not produce a highly-polished surface, as such a surface is objectionable, inasmuch as it will not so readily take the ink.

I am aware that printing-surfaces have been prepared from wire-cloth by passing the same between highly-polished rolls to produce the necessary flattening of the wires for printing, and do not claim such as my invention, from which mine can be readily distinguished by its appearance and the superiority of its result when used.

When the cloth is prepared as last stated, it presents a polished surface, which is objectionable for the reasons stated above, and, furthermore,the wires at their point of intersection are pressed into one another, thereby compressing the metal to such an extent at these points that it becomes very hard and (No model.)

brittle and renders the wire-cloth more suscep tible to fracture. Again, when the cloth is submitted to pressure, both sides are necessarily attened, thereby greatly reducing the thickness of the wires in a direction at right anglesto the surface of the cloth. This in the case of coarsely-woven cloth made from very iine strands of wire is very objectionable,inasmuch as there would not be a sufficient space between the printing-surface and its backing support to prevent the ink reaching that portion of the support exposed between the intersticcs of the cloth, and transfer the same when printing.

The advantages of my improvement in producing a printing-surface from the wire-cloth are: iirst, it produces a surface that will readily take the ink; second, there is no abnormal compression of the metal at the intersecting points of the wires; third, the iiattening being only on one side, the distance between the printing-surface and its support is at its maximum; fourth, the surface being produced by abrasion admits of a surface being prepared in which the thickness 0f the lines maybe made to progressively increase or decrease from a lixed point or points, and thereby produce a print which will have the appearance of being shaded to or froma tired point or points.

Having thus fully described my invention, what I claim is- As an improved article of manufacture, a ground wire-cloth printing-surface, substantially as described.
