No Drawing.

To all whom 'it may concern:

Be it known that I, ROBERT JoHN Cnirowicn MITCHELL; a subject of the King of Great Britain and Ireland, residing at Morton Hall, Swinderby, Lincoln, England, have invented certain new and useful Improvements in Processes of Printing on Felt and the Like, ofwhich the following is a specification.

This invention relates to the printing of felt and like fabrics having a close even surface.

Heretofore felt has been decoratively treated by printing designs thereon with engraved rollers or blocks and in anilin or other colors which are fixed by steamin Such process of fixing involves a subsequent washing and finishing of the material, and the artistic results obtainable are consequently very limited and not such as to enable the felt that has been thus decorated by the printing of colored patterns or designs thereon, to be applied to many services to which it is otherwise Well adapted.

The object of this invention is to obviate the necessity for the aforesaid fixing of the colors by steaming and the subsequent washing and finishing operation, and to print designs and produce decorative or artistic effer-ts upon the felt that have hitherto been unattainable on such material.

I have found that the best decorative effects in the color printing of felt and like fabrics, are obtainable only by printing upon such material when it is in the finished condition and with ordinary oil or self-fixing lithographic colors. I' have further found that to attain the desired result the colors must ndthc allo'i'ved to penetrate beneath the 40 surface of, or soak into, the fabric, as such penetration causes a spreading of the pattern or design which is thereby blurred or caused to present a blotchy or similarly impaired appearance.

My invention comprises the process of printing felt by lithographic printing means wherein the felt is first provided with a white or other ground color so as to form an effective base for the pattern at the parts on which the colors are printed,

In carrying the invention into effect in one convenient manner, I employ for the printing operation any ordinary or suitable lithographic printing machine having, for

example. an impression cylinder arranged me :i fiat bed on which are placed stones Specification of Letters Patent.

PROCESS OF PRINTING ON FELT AN]? THE LIKE.

Patented that; 5,

or their equivalent to be used for the The required pattern or design to be printed on the felt is formed upon or transferred from a drawing to the said stones in any 6 ordinary manner.

When printing on unn'oven or or felt, the latter is fed into the -ne such a Way tl at the direction in which it naturally res'i s a stret hing action coincides with the direction 1 which the printing machine tends to stretch it, so that more accurate register of the colors is obtained than would otherwise be possible.

As a further means for insuring the aforesaid accurate register of the colors, the felt may be placed upon and passed through the printing machine with a sheet or backing of -non-stretching material having a surrace such as will preventthe felt from indcpcnd ent movement thereon during the printing operation. In somerases a non-stretching surface maybe provided either at the back or front of the material; such surface may be formed by treating the felt with one or 83 more suitable and known substanc such as a solution of nitrocellulose; which will produce a non-stretching film or skin.

Prior to printing the felt may be dyed to any suitable color, and when printed can 35 have its whole surface covered with a wash able varnish; r the design alone may he varnished in any ordinary manner.

I first print the felt or i ilte material, (on the parts where the decorative colors are to be subseanently rinted}, with a sol ground color, white, Till. ed with suitable oriers, varnish, oil or other mate rials so that the mpression on the material i dries quickly. Said ground color, which forms a bed or surface for the sn quest colors, may if desired be produced by methan one impression, each impression b applied by a lithographic or equivale: printing slab or surface as aforesaid. u the ground color is sufficiently dry, va rious colors forming the design are p .ted thereon, each color being of course allowed to dry before another is impressed. this a r method the colors printed are given greater 1? prominence and brightness, thus increasing the artistic efiect. I

The grrnind color aforesaid. composed of pigment color, driers, varnish, and oil plied by lithographic printing surf quickly dries upon and adheres in film to the felt Without penetration its surface and owing to iis composition and method of applies/83mm presents a serious capable. of reoelvmg hthographlo prlntmg eoioa's also applied by lithographic surfaces.
