EDUARD SOHOENING, OF BERLIN, GERMANY.

PRINTING BY MEANS OF ELASTIC ROLLERS OR PLATES.

SPECIFICATION forming part of Letters Patent N0. 751,946, dated February 9, 1904. Application filed May 26, 1903. Serial No. 158,853. (No model.)

To all whom it may concerm Be it known that I, EDUARD SOHOENING, a subject of the Emperor of Germany, residing at Berlin, Germany, have invented certain new and useful Improvements in Printing by Means of Elastic Rollers or Plates, fully described and represented in the following specification and accompanying drawings, forming a part of the same.

My invention relates to printing-machines, and more particularly to that class of machines employed for grounding wall-paper, and has for its object to produce an ornamental ground on the paper. a

A further object of the invention is to produce a ground on the paper having two shades of the same color at one and the same opera tion and by the same printing-surface.

A still further object of the invention is to utilize the pattern-surface and the color removed from the printing-surface in producing the pattern on a printing-surface to print a second web, thus producing a duplex machine.

.The invention consists in producing a pattern in the color on the printing-surface and then transferring the pattern thus producedto a Web of paper or the like. v The invention also consists in producing the pattern in the color on the printing-surface by means of a pattern-surface coming in contact with the printing-surface.

' The invention further consists in printing a second web of paper by means of the color removed by the pattern-surface from the printing-surface in producing the pattern for printing the first web.

Reference is to be had to the accompanying drawings, forming a part of the specification, and wherein similar letters and numerals of reference indicate similar parts in all of the figures.

Figure 1 is a side elevation of a portion of a grounding-machine having my improvement applied. Fig. 2 is a sectional view of the same. Fig. 3 is a front elevation. Fig. 4: is a plan View of the printing-roller having the pattern produced in the color on its surface, and Fig. 5 is a sectional view showing the elastic printing-roller; c, the distributingroller; 06, the color or inking roller; 6, the color or ink pan in which the roller 66 revolves, and f the web of paper fed from a feed-roller (not shown) to and over the roller a to receive the color from the printing-roller 6. The webbearing roller, the printing-roller, the distributing-roller, and the inking-roller are all operated in the usual manner. The printingroller 6 is mounted in adjustable bearings 6, which are mounted in a movable support 6 The support 6 is adjusted by means of the cam 6 and lever 6*. The distributing-roller 'c and inking-roller (Z are mounted in adjustable bearings c 03, respectively, to permit them to be adjustable with respect to the printing-roller. The ink or color pan 6 is adjusted to and from the ink or color roller 66 by means of the shaft g, provided With crank-arms h, engaging grooves i in the frame, the shaft 9 being operated by the handle All of the above parts are of'the usual, construction and about which there is nothing new.

Mounted at each end of the frame A and attached to the support 6 of the printing-roller 6, so as to be adjusted therewith by the means hereinbefore described for adjusting the said support, are yokes 1. In these yokes a pattern-roller 2, having any desired pattern produced on its surface, is mounted so as to contact with the printing-roller 6. As shown in the drawings, the pattern-roller is revolved by frictional contact with the printing-rollembut it may be operated by any other suitable means. The pattern-roller is mounted in slid-- ing bearings 3, which rest on springs 4:, and saidbearings are engaged by screws 5, working in the yokes 1. By thus mounting the pattern-roller it will be yieldingly held in contact with the printing-roller 6 and can be adjusted to bear with more or less pressure upon the said roller, as circumstances may require.

The closer the pattern-roller is placed to the web-that is to say, the nearer its point of contact with the printing-roller is to the point of contact of the printing-roller with the .web the more distinct will the pattern be produced upon the web of paper.

As shown in the drawings, the patternroller 2 has diamond-shaped figures produced thereon, but it is obvious that the pattern can be of any other shape or design. In fact, any form of pattern-roller can be used, and even a plain wooden roller may be used with good results.

In operation the ink or color is applied to the printing-roller b by means of the rollers 0 and cl, as usual, and the pattern-roller 2, contacting with the roller Z), produces the pattern in the color on said printing-roller, and the i said printing-roller then prints the pattern on the web at the point of contact of said roller with the web-carrying roller 60.

With the design of pattern-roller shown in the drawings, the diamond-shaped figures being the raised portions and the cross-lines the sunken portions, the figures or raised portions on the pattern-roller will wholly or partially remove the color from portions of the printing-roller, while none of the color will be removed by the cross-lines or sunken portions, and consequently the figures produced on the web by the printing-roller will be of a very light shade, while the cross-lines will be of a shade of the full depth of coloring substance applied to the printing-roller.

In order to keep the pattern-roller clean and at the same time utilize the color removed from the printing-roller by the pattern-roller in producing the pattern on the printing-roller for grounding the first web, I arrange above the pattern-roller a roller 6. Between this roller and the pattern-roller a second web 7 is passed, as shown in Fig. 5, so that the pattern-roller prints upon this second web a pattern the reverse of that produced on the first web.

Instead of transferring the color removed by the pattern-roller from the printing-roller direct to this second web the color may be transferred to another printing-roller having color-applying devices, so that by employing and very lightly applying a different color from that employed for printing the first web a figured pattern in varied colors can be produced on this second web. The same result can be produced by previously coating the second web with a different color. By this latter arrangement it will be seen that I am enabled not only to print two webs at the same time, but that I employ the pattern-roller for printing the second web and utilize the color removed by it from the printing-roller in producing the pattern thereon for the first web.

While I have shown a printing-roller and a pattern-roller, yet it is obvious that the invention could be carried out equally as well by employing printing and pattern surfaces in the form of plates.

An elastic printing roller or surface is also not absolutely necessary to the successful carrying out of the invention. I have found out by actual tests that good results can be obtained by the employment of a pattern roller or surface in connection with a plain hard printing roller or surface; but when such printing-surface is used to obtain good results the web-bearing roller should be elastic.

When a plain wooden pattern-roller is employed, the roller by contacting with the printing-roller impresses the grain of the wood on the printing-roller by removing the color from the same corresponding to the grain, and the printing-roller transfers the grain-figuring to the web the same as hereinbefore described.

It will thus be seen that by employing wooden pattern-rollers I am enabled to produce difi'erent patterns by simply using different kinds of wood.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
