METHOD OF WATERMARKING PAPER.
Specification of Letters Patent.
Patented Apr. 28, 191%.
Application'iiled October 6, 1909. Serial No. 521,354.
To aZZ wIm m it may concern:
Be it known that I, WILLIAM J. F. Main- HOF, a citizen of the United States, and resident of the borough of Bronx, in the city and. Stateof New York, have invented a new and useful Method of Watermarking Paper, of which the following is a specification.
This invention relates to an improved method of water-markin paper, with the object in view of providing a method by which paper may be water-marked at any time, even after it has been manufactured, and without the necessity of any preparatory treatment; and in carrying out which method any ordinary printing or embossing form may be used.
It has heretofore been customary to watermark paper during the process of its manufacture, thus requiring a very large amount of paper to be stamped with a given mark in order to prevent the cost of water-marking rendering the price of the paper commercially prohibitive.
My method is especially adapted for marking small lots .of paper because it may be carried out in connection with finished paper.
A practical form of means for carrying out my method is represented in the accompanying drawings, in which, Figure 1 represents a detail verticalsection through the cylinders of a rotary cylinder printing or embossing machine arranged to carry out my method; Fig. 2 represents a detail face view of the form cylinder; Fig. 3 represents a similar view of the impression cylinder with the roughened sheet in place; Fig. 4 represents a detail view of a piece of paper'after being Water-marked by the apparatus represented in Figs. 1, 2 and 3; Fig. 5 represents a detail vertical section through a rotary flat bed printing or embossing machine, with the sur face of the impression cylinder roughened, ar-
ranged to carry out my method by a modified means: Fig. 6 represents a detail face view of the form; Fig. 7 represents a detail face view of the impression cylinder, showing the roughened portion, and Fig. 8 represents a detail view of a piece of paper watermarked by the apparatus represented in Figs. 5, 6, 7
Referring to the apparatus represented in Figs. 1 to 3 inclusive; the form cylinder is denoted by 1 and the impression cylinder by 2. The former is provided with the ordinary form or plate 3 secured thereon by the clamps 4 and screws 5. The impression cyllnder is provided, at a. point registering wlth the form or plate 3 on the form cylinder,
with a roughened surface 6, which, in the present instance, consists of a sheet of textile fabric, such as linen, secured in position on the impression cylinder by clamps 7 and screws 8. The web or sheet to be marked is indicated by 9.
' Referring now to the apparatus rcpresented in Figs. 5, 6, 7 the bed of a rotary flat bed embossing or printing machine is lndicated by 10, and the form 11 is held thereon by clamps 19.. The impression cylinder is represented by 13 and is provided with the usual grippers 14 for receiving sheets to' be marked from the sheet feeding table 15.
The impression cylinder is further provided,
at point'ada ted to register with the.form on the bed, wit roughened surfaces 16, indicated in the present instance by a multitude of fine adjacent protuberances. The sheet to be marked is denoted by 17 In the apparatus set forth in Figs. 1, 2 and 3, as well as in that set forth in Figs. 5, 6, '7, the forms or plates 3 and 11 are provided on their faces with a raised character 18, in the present instance, A. r
In operation, the sheets to be watermarked are subjected to the action of the cylinders represented in ig. 1, or to the action of the cylinder and bed represented in Fig. 5. As a result, the character on the forms 3 or 11 will be embossed on the sheets in exact simulation of water-marks. The roughened surface of the impression cylin- .der causes the character to have a dull apparatively cheap and rapid and extremely desirable inthat it permits the commercial water-marking of small lots of paper after the latter is manufactured.
It is to be understood that various changes may be made in the form, construction and arrangement of the means for carrying out my method; hence I do not wish to limit myself strictly to the mechanism herein shown and described, but
' What I claim is:
1. The method of water-marking paper consisting in subjecting the paper to a direct contact with the form of a printing or emnoeeeoo In testimony, that I claim the foregoing as It my invention, I have signed my name in presence of tWo Witnesses, this fourth day of October 1909. I
