MANUFACTURE OF ORNAM'ENTAL PAPER.

. Q SPECIFICATION forming part of Letters Patent No. 293,228, dated February 12, I884.

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

To all whom it may concern Be it known that I, WVINrHRor MURRAY CRANE, a citizen of theUnited States, resid- State of Massachusetts, have invented anew and useful Improvement in the Manufacture of Ornamental Paper, of which the following is a specification My invention relates to a method of print ing or coloring paper during the process of manufacture. Prior to my invention the coloring of paper had been eflected by dyeing the pulp before forming the same into paper, whereby the body of the sheet was made of a uniform color throughout. Liquid colors were in some cases applied to the unsolidified pulp webbefore the same had been pressed or dried,

to partially penetrate and spread within or through the body of the web in an irregular manner, and the web after compression and drying has also been superficially dyed by completely immersing the same in a colored liquid size. My invention differs essentially from these; and it consists in applying the coloring material 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 passing. through the press-rolls of the paper-making machine. It embraces a continuous process of printing of one or more colors upon a portion or upon the whole of either or both surfaces of the paper, or the imprinting thereupon of designs or figures of any kind. My improved process is not only well adapted for producing paper for bank-notes, drafts, checks, certificates, passage-tickets, and similar vouchers, in which it is necessary or'desirable to guard against a fraudulent removal of writing from the surface of the paper, or the alteration of figures, letters, or characters upon the same; but it is also applicable to the manufacture of ornaany purpose for which such paper is commonly employed. i

In the accompanying drawings I have shown ing the parts necessary to enable one method in whfch- Figure 1 shows in section a portion of such machine, together with mechanism which may be used for applying the colors to the paper; and Fig. 2 is a front view of the same. In practicing my invention I prefer to make use of an ordinary paper-making machine such, for example, as the well kno wn Fourdrinier machine. The pulp is prepared and refined in the usual manner, being afterward 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 two or 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 is shown at A A in Fig. 1 of the drawings, which represents a part of the well-known Fourdrinier machine. In the ordinary process of paper-making 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 G, &c., 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.

The apparatus for printing or coloring the paper according to my invention may be mounted upon the frame F of the Fourdrinier machine at a point between the press-rolls A A and the first drying-cylinder, B. A convenient form of this apparatus is shown inelevation or end view in Fig. 1, andin an enlarged front View in Fig. 2. It consists of a cylinder, G, which may be termed the color-roll-' er, and which is so mounted that its. lower' portion is immersed, asjt revolves, in a coloring liquid or dye, (1, contained in a suitable vessel, D. The color-roller G is caused to revolve by means of a pulley, g, to which motion may be imparted from a belt connected to any convenient portion of the machinery.

A printing-roller, H, is mounted in bearings or journals above the color-roller G, and may receive its motion therefrom by friction. Above the printing-roller is a small jockeyroller, I, which may be caused to press, by means of springs or otherwise, against the printing-roller H. The web of paper to 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 colorroller G as it revolves, and is continuously transferred to or imprinted upon the undermost surface of the web of paper w. In illustration of this process, I have shown in Fig.2 a simple form of printing-roller adapted 'to produce a design consisting of a series of lon- I gitudinal parallel colored stripes upon the web.

It is evident that a great variety of other and different designs may be produced in the same manner simply by varying the design upon the surface of the printing-roller H. If a plain printing-roller is used, without any design whatever upon its surface, a uniform tint of any required color may be imparted to the paper. By using variously-grooved rollers, such as shown in the drawings, any required number of parallel stripes may by imprinted upon the paper, and by employing two or more separate rollers, G, upon the same axis different colors may be applied simultaneous ly. Ornamental designssuch as national flags, handkerchiefs, or the likemay be engraved upon the surface of the roller H and 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 imprint designs on both sides of the paper, I make use of a second set of ro1lers,-G, H, and I, so that the web w, 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 printing-roller H and the second jockey-roller l, and finallyover the roller 0 to the second dryingcylinder G, andso 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 cutting-machine may be so adjusted in connection with the Fourdrinier machine that sheets will be automatically cut off from the continuous web after sizing and drying, so that-each separate sheet will contain one copy of the design imprinted upon the roller, which design will ap pear on one 01" both sides of the sheet, as the 0 case may be.

By applying the color in the manner hereinbefore described-that is to say, after the web has been pressed and the greater part of its moisture expe1ledthe color does not pene- 5 5 trate far enough into the fiber of the paper to cause it to spread and become spotted or indistinct; nor can writing be fraudulently erased therefrom Without exposing the inner fibers of the paper, and thereby changing its apparcut 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 do not desire to restrict my invention to the particular means and appliances which I have described and shown for practicing the same.

I claim as my invention- 1. The hereinbefore-described art, method,

or process of surface-printing or coloring paper during'the process of manufacture, which consists in applying the coloring material to either or both surfaces of the continuous web. after the same has been consolidated and partially 7 5 dried by passing through the press-rolls of the machine, asset forth.

2. The new article of manufacture hereinbefore described, which consists of a paper surface printed or colored after the web has been compressed and a portion of its moisture expelled by passing through the press-rolls of the paper-machine in the process of manufacture.

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