To all whom it may concern Be it known that 1, CHARLES D. Jncons, a citizen of the United States, and. a resident of South Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Means for Watermarking Paper, of which the following is a specification.

, My invention relates to making watermarks in paper and to the means and method whereby said Water marks are produced in the paper, and more particularly, both as to the instrumentalities and methods employed, to making intagliated Water marks on those produced by increasing thickness of the paper in parts or the whole of a design over the thickness of the surrounding sheet, and also to those water marks wherein the feature just described is combined or used in a water mark design wherein other parts are thinner than the paper in the surrounding sheet.

Further objects of my invention are to produce such a water-mark design, while avoiding thinning the paper surrounding the design, which thinning of the surrounding paper both destroys the artistic cfl'ect of the design and also weakens or impairs the strength of the paper, both of which are very important considerations; also, the above object is equally or even more desirable where the Water-mark design comprises both parts of greater and less transluccncv than the other parts of the sheet.

Additional objects of the invention are to provide for the rapid and economical production of Water marks of the kinds described, and of'the instrumentalities and devices for producing same; to provide against the destruction and impairment of the design producing instrumentalities and also against the consequent deterioration in the appearance and artistic value of the Water mark itself; to provide instrument/air P ties and means adapted to produce such Watermarks varying Widely in size and character, and which also realizes the objects and advantages set 'forth herein and those apparent herefrom; to provide novel andv useful instrumentalities for realizing and effecting the objects and advantages herein enumerated and'referred to.

Other olojects and advantages will be set forth hereinafter or will be, obvious herefrom, f

The inve'ntionconsists in the novel means, articles, constructions, methdds, arrangements and improvements herein shown and described. I l

The accompanying drawings referredto herein and formin a part hereof, illustrate onesmbodimentof the invention, and with the description serve to explain the principles thereof.

Of the drawings: Figure 1 is a perspeo tive view of a dandy roll; Fig. 2 is an enlarged cross-section on line A5-B of Fig; 1; Fig. 3 is an enlarged plan o:f the central part of Fig. 1; and Fig. 4 is-a similar view showing the use of supports around a. roletively small design.

In many connections is very desirable to have Water-marks of great artistic value and frequently ,of striking and original design, and many artistic, striking and original effects can be secured only by reducing the translucency of the paper: instead of in- I creasin its translucency, as practised in the art at t e present time. Other unusual and original effects are secured by united and contrasted employment in a single design of lines or parts of greater translucency with lines or parts of less translucency than" the remainder of the paper. 1 v v In making a design of the kind described, in which certain parts ofthe water-mark are thicker than the normal thickness of the paper, the corresponding parts of the design as formed'in the gauzecover sheet of the dandy roll, or other correspondin cover sheet, are sunken or integliated. fiat is, those parts of the design are'sunk below the general surface of the cover which passes about and rests upon'the surface or periphcry of the body of the dandy roll. It will be clear, of course, that the pulp mixture running into or being formed into these sunken or intagliated parts of the gauze cover will form a more dense'jportion in the paper web or sheet representin the corresponding part of the designs" f a portion of the cover be raised or embossed and a portion thereof also be sunken or intagliated, the resultant design formed in the till body having a depres sed area in its periph ery, of a plurality of interchangeable cever sheets, each'of said sheets adapted to fit closely around the dandy rolibody, and each 1 sheet carrying a sunken or intagliated de ery, of a piuraiity'of interchangeable cover sheets, each .of said sheets adapted to fit eloseiy around the dandy roll body, and each. sheet carrying a sunken or intagii'ated design adapted to be contained within said depressed area, saidde'signs varying in area or extent and ocenpyi-ng correspondingly more or less of. said depression and supports'heneath cover sheet aronnd said sunken designand Within said depressed, area in the'periphery of the dandy r011 body when the design is of less area or extent lea than said depressed area in the dandy r011 body.

.5. The .conibination with a dandy r011 bodyhaving a plurality of depressed areas formed in its periphery, of a plurality of interchangeahle eo'ver sheets, each of said sheets adapted to fit closely around the dandy 1-011 body, said cover. sheets each carrying a pluraiity of intag iiat'ed or sunken designs, said." designs heingof various sizes and variously arranged upon the respective sheets, but all beingarranged so as to fit Within saiddepressions in said dandy r011 bod-y when the particular cover sheet is mountednpon the dandy r011 body,

, In testimony whereof, I have signed 'my name to this specification, inthe presence of 40 two subscribing witnesses.
