MACHINERY .FOR MANUFACTURING ORNAMENTAL PAPER.

SPECIFICATION forming part of Letters Patent No. 293,229, dated February 12, 1884.

' Application filed July 5,1883. (No model.) i

To all whom it may concern Beit known that I, \Vru'rnnor MURRAY CRANE, a citizen of the United States, residing in Dalton, in the county of Berkshire and State of Massachusetts, have invented a new and useful Improvement in Machinery .for Manufacturing Ornamental Paper, of which 7 the following is a specification.

same had been pressed or dried. The web had also been superficially dyed by completely im} mersing the same in a colored liquid size after having been pressed and dried. My invention consists in an improved mechanism or apparatus whereby coloring ma terial is applied to either or both surfaces of the continuous web of paper after the Same has been solidified and the greater part of its moisture expelled by its passage through the press-rolls of the paper'machine, and I am thereby able to apply one or more colors bya continuous process up 011 a portion or upon the whole of either or both surfaces of the paper, and to imprint upon the paper in this manner designs or figures of any kind. My improved machinery is therefore not only well adapted for manufacturing pap er for bank-n otes, drafts, checks, certificates, passage-tickets, and similar vouchers in which it is necessary or desira bleto guard against fraudulent removal of written or printed characters upon the surface of the paper, or the falsification of figures, letters, or characters upon the same, but it is also applicable to the manufacture of ornamental, striped, figured, or coloredpaper for any purpose for which such paper is commonly employed.

I11 the drawings I have shown a portion of a paper-making machine embracing the parts necessary to enable my improvements to be understood, in which- Figure 1 shows, in elevation, a portion of such machine, together with the mechanism which I employ for applying the colors to the paper. Fig. 2 is-a front view of said mechanism, and Fig. 3 is a modification adapted for printing in more than one color. 1

In applying my invention I preferto combine it with an ordinary papermaking machine-such, for example, as the well-known Fourdrinier machine. The pulp is prepared and refined in the usual mannenbeing after- -ward diluted with water and formed into a continuous sheet or web upon an endless wire cloth or apron, whence it is transferred to a felt blanket, still in a green and unsolidified condition. This blanket conveys the web to a series of twoor more pairs of press-rolls, by which it is consolidated and compressed and the greater part of its moisture expelled; The terminal pair of rolls of the series isshown at A A in Fig. 1 of the drawings, which rep& resents a part of the well-known Fourdrinier machine. In the ordinary process of papermaking, the web 10, after emerging from the press-rolls, is next conveyed directly by an endless felt to the first of a series of steamheated hollow drying-cylinders B 0, 8m. which revolve slowly by power and serve to gradually dry the paper as it passes along and around them in the direction indicated by the arrows in the figure.

1 and in an enlarged front viewin Fig. 2.- It 1 consists of a cylinder, G, which'may be termed the color-roller, and which is'so mounted that its lower portion is immersed, as it re volves, in a coloring liquid or die, (1, contained in a suitable reservoir, D. e is causedto revolve by means of apulley, 9;

The color-rollerG '..j

to'which motion may be imparted from abelt or gearing connected to any convenient portion of the moving machinery. A printingroller, H, is mounted in bearings or journals above the color-roller G, and may receive its motion therefrom by friction. It is important that the periphery of this color-roller G, and consequently that of the printing-roller H, should move at precisely the same speed as the periphery of the press-rolls A A, so that the web of paper w will pass uniformly through the Fourdrinier machine that sheets will be the printing mechanism without longitudinal automatically out off from the continuous web after sizing and drying, so that each separate v strain, Above the printing-roller is placeda small jockey-roller, I, which should be caused to press, by means of springs or otherwise, toward the printing-roller H. The web of paper in its passage through the machine, as indicated by the arrows, is led between the printing-roller H and the jockey-roller I, and hence when the machine is in operation the coloring-matter is taken by the printing-roller H from the color-roller G as it revolves, and is continuously transferred to or imprinted upon the undermost surface of the web of pa per 10.

In illustration of the process, I have shown in Fig. 2 a simple form of )rin'ting-roller adapted to produce a design consisting of a series of longitudinal parallel colored stripes upon the paper web. It is evident that a great variety of other and different designs may be pro duced in the same manner simply by varying the design upon the surface of the printing-roller H. If a plain printingroller is used, without any design whatever upon its surface, a uniform tint of any required color may be imparted to the paper.

Byusing variouslyrgrooved rollerssuch as shown in the drawingsany required number of parallel stripes may be imprinted upon the paper, and by employing a divided roller or two or more separate rollers, G G, upon the same axis, as shown in Fig. '3, each revolving in a separate compartment of the reservoir D, supplied with different coloring materials, different colors may be applied simultaneously. Ornamental designssuch as national flags, handkerchiefs, or the like-may be engraved upon the surface of the roller H, and at each revolution of thelatter they may be transferred in one or more colors ;to the paper web as it passes through the machine.

In case it is desired to apply color or im print designs on both sides of the paper, I

make use of a second set of rollers, as shown at G, H, and I, so that the web 10, after passing the first dryingcylinder, B, and thus drying the color first applied, may be led over the roller 0, and thence between the second printingroller, H, and the second jockey, I, and finally over the roller.c, to the second dryingeylinder, 0, and so on through the machine in the usual manner.

It is obvious that any special ornamental design or pattern engraved upon the printingroller H will be repeated upon the web at every revolution of the said roller. A cuttingmachine may be so adjusted in connection with sheet will contain one copy of the design imprinted upon the roller, which design will appear on one or both sides of the sheet, as the case maybe.

By applying the color in the manner hereinbefore describedthat is to say, after the web has been pressed and 'the greater part of its 1noistureexpelledit will not penetrate far enough into the fiber of the paper to spread laterally and become spotted or indistinct; nor can writing be fraudulently erased therefrom without exposing the inner fibers of the paper, and thereby changing its apparent color. By the use'of my invention paper may be ornamented in any desired way by the application of designs and colors during the process of manufacture at a-trifling cost.

I claimas my invention 1. In a paper-making machine, the combination, substantially as hereinbefore set forth, of the press-rollers, the drying-cylinders, and the color-printing roller revolving in contact with the paper web between the press-rollers and the drying-cylinders.

2. In a paper-making machine, the combination, substantially as hereinbefore set forth, of the press-rollers, two or more drying-cylinders, and two color-printing rollers, one of the latter revolving in contact with the paper web at a point between the pressrollers and the d-rying-cylinders, and the other in like manner at a point between two drying-cylinders.

3. In a paper-making machine, the combination, substantially as h'ereinbefore set forth, of the press-rollers, the color-roller, the printing-roller, the jockey-roller, and mechanism, substantially such as described, whereby the periphery of the printingroller is caused to move at the same rate of speed as the periphery of the press-rollers.

4. In a paper1naking machine, the combination, substantially as hereinbefore set forth, of the press-rollers, the drying-cylinders, the printing-roller, the divided colorroller, and the reservoir of coloring material divided in to compartments corresponding to the' divisions of said color-roller.

Intestimony whereof I have hereunto subscribed my name this 26th day of June, A. D. 1883.

\VINTHROP MURRAY CRANE.
