To .all whom t may/.concern lBe it known that l, MANUEL een, a citizen of the llnited States, residing in Philadelphia, Pennsylvania, have invente' ed a Frocess of Urnamenting Coated Paper,

of which the following is a'specifi'cation.

My inventionV relates tothe manufacture of coated paper, cardboard and l.products of a similar nature, andthe object ofmy invention is to produce a highly ornamental surface edect upon such coated paper, cardboard,.and the like.

Coated papers are, of course, well known;

, the character of the coating is a matter that lli has engaged the attention of many inventors, and the` embossing of paper, whether coated or not, has been carried out in A4many ways.` lThe process forming the subject of my'm-` vention, however, while it partakes somewhat of the nature of an embossing of the coated paper, -has an additional function distinguishing it from anything heretofore accomplished along this line, which is.2 the compression of ortions of the coating so that when a light coating is applied to a `sheet of dark colored stock, indefinite gradations of color lor tone. are produced; the darker stock showing through the thinner or more highly compressed areas of the coating. These and other featuresof my invention are more fully -described hereinafter, reference being had to theaccompanying drawing in which l have endeavored to illustrate, more or less diagrammatically, one of the many designs which may be produced in car.

rying out the process forming the subject of my invention, in which:

Figure l, is a perspective view of a section of coated paper or cardboard; Fig. 2,'is .a similar perspective view showing one edect which may be produced upon the coating in carrying out lmy invention ;T Fig. 3, is an enlarged sectional View of part of" an impression pad, and Fig.4 l, is a diagrammatic view illustrating one form of means for producing my improved product.

ln carrying my invention into ed'ect, l preferably proceed as follows: l take coated stock, as it is termed, which may be thin paper of any color, preferably of a dark tone` any of the materials employed in the manufacture of paper, cardboard or the like and ricton QLettel-:S'Patent Patented dan.. Qld., lhll'l, application Pared Septmberie, 1,915. 'j serial No. 51,0%. i

i of any'cjlesired tone, shade orcolor that such material happens to be. rllhis paper is coated in the lusual manner by a wet coating material, which may be of any color,'preferably lighter than the stock or paper to which it is or equivalent material is in a finely divided state, substantially in solution. 'llhe wet ccoatingfapplie'd to. thefsheet is dried in any usual o1" well' lknown manner common in the art.

D ln practice, l have treated sheets substantially twenty-two by twenty-eight inches; the same beingA one of the standard paper sizes, although other sizes may be employed, and this treatment, according to my invention, is as follows: ll build up a pile of smooth metal plates 1, impression pads 2, and sheets of coated paper or coated'cardboard sheets 3 upon which l desire to show patterns from such impression pads.A Ar pile so prepared is then passed a, number of times between a pair of smooth rolls l and 5, back andV forth, and as this pile has interspersed through it a number of the smooth metal plates 1, the repeated movement between the rolls will have the e'ect of causing a certain amount of slip between the impression pads and the coated surface of the paper lor card with which they are in con* tact, with the consequent result` that the varying heights of the surface of the patterns or designs of suchimpression pads will impart yarying degrees. of pressure to various portions of the coating, polishing the samel to a certain extentand condensing portions thereof. The nal result will be indefinite areas of gradations of tone in the coating, the character of which will depend upon the character of design carried by the impression pads. lt will be understood that the `amount ofA slip is slight and that its extent may be regulated within certain limits by the amount of pressure imparted to the piles of sheets and the number of metal plates employed.

'lhe result is an ornamental coated paper having a most peculiar mottling or surface eect, rarely partaking of the exact pattern of the impression pads, although having certain features of the same.

lllhe impression pads which l employ consist preferably of a sheet of press-board as it is called, upon one or both surfaces of which asheet fabric may be secured by a suitable adhesive, and over this fabric i se'- cure, preferably by an adhesive, a thin sheet of paper or fabric. If the latter material is employed, silk, or linen, or thin muslin may be used. in some instances, the placing of a section of fabric on one side of the press-board support with the predominantv any of the many weaves in which various fabrics are produced. i have also used Sand paper of various degrees of ineness with admirable results.

In treating both sides of a 'sheet of paper, cardboard and the like previously coated7 it can be accomplished at onel operation by employing suitable impression pads on opposite sides of the same, which pad may have the samel or different designs. When it is desired to treat sheets coated on one side only, two sheets may be placed back to back with the coated surfaces in contact with the impression pads. in all instances, there appears to be a displacement of a portion .of the coating 'by the higher portions of the impression pads.

in lieu of employing paper ystock-.of a

shade darker than the coating material, i may take plain stock of any character and color, and apply to Vthe same a coating of a dark shade or tone which is allowed to dry, and then apply to the dark coated stock coloring material lof a lighter shade or tone. The double coated sheets thus prepared are then subjected to pressure inthe manner described with reference to the other form of coated sheets.

' It will be understood, of course, that light colored stock may be covered with dark coating material and that stock may be first covered with a light coating material and then with .al dark coatingfmaterial and subjected to pressure that will compress the final coating layer and showV indefinite areas of the/lighter stock or coating layer through the same.

i claim 1. The process of ornamenting paper sheets, which consists in coating the same,

drying the coating, subjecting the coated.

sheets to pressure, and effecting slip of the sheets whileL undergoing such pressure whereby indefinite'areas of the' coated surface are impressed or compressed in varying degrees of depth.

2. The process of ornamenting paper sheets, which consists in coating the same, drying the coating, subjecting the coated sheets to rolling pressure, and effecting slip of the sheets while undergoing such rolling pressure whereby indefinite areas of the coated surface are impressed or compressed in varying degrees of depth.

3 The process of ornamenting paper sheets, which consists in coating the same, drying the coating, placing impression pads in contact with the coated surface, subjecting the coated shifts topressure,'and effecting slip of the pads and sheets while undergoing such pressure whereby indenite areas of the coated surface are impressed or compressed in yarying degrees of depth.

4. The process" of ornamenting paper sheets, which consists in coating the same, dryingthe coating, placing impression pads in contact with the coated surface, subjecting the coated sheets to rolling pressure, and effecting slip of the pads and sheets while undergoing such rolling pressure whereby indefinite areas of the coated surface are impressed or compressed in varying degrees of depth.

. 5. The process of ornamenting paper sheets, which consists in coating paper stock of a dark shade or tone with a coating ma.- terial of a light shade or tone, drying the coating, then subjecting the coated sheets to pressure between sheets or pads of fabric having an irregular or uneven surface, and effecting slip of the coated sheets while undergoing such pressure. f

6. The process of ornamenting paper sheets, which consists in preliminarily coating paper stock with a coating material, drying the same, then applying a secondlayer vof coating material of a shade orl tone differing from the first, drying the second coating, then subjecting thecoated sheets to a rolling pressure between sheets or pads of fabric having an irregular or uneven surface, and effecting slip of the coated sheets while undergoing such pressure.

7, The process of ornamenting paper sheets, which consists in preliminarily coating paper stock with a dark coating material, drying the same, applying a layer olf lighter coating material to the first coat, dryingthe second coating, then subjecting the coated sheets to a rolling pressure between sheets or pads of fabric having an irregular or uneven surface, and effecting slip ofthe sheets while undergoing such pressure whereby indefinite areas of the second coated surface are imp essed or compressed .in varying degrees o` depth.

8. The process herein described of ornamenting paper sheets, which process consists in supplying a sheet of one color with a coating of a contrasting color; then drying the coating; then subjectingthe coated sheet to contact With an impression pad having high and 10W vpoints on its surface and subjecting the pad to pressure to cause the varying heights of the surface of the pad to impart varying degrees of pressure to` various parts of the coating and to thereby produce indefinite gradations of color or tone on the sheet.

9. r][`he process herein described of ornamenting paper sheets, which consists in supplying a paper sheet of one color With a coating of a contrasting color; then drying the coating; then subjecting the coated sheet to Contact with an impression pad having high and low points on its surface and subjecting the pad to a rolling pressurel to cause the varying heights of the surface of the pad to impart varying degrees of pressure to various parts of the coating to displace and spread the latter and produce indefinite gradations of color or tone on the sheet.
