SAFETY-PAPER.
Specification of Letters Patent. Patented Mai. 29, 1910.
Application filed February 25, 1907. Serial No. 359,148.
To all whom it may concern: I I
Be it known that I, JAMES R; WILSON, a citizen of the United States, residing at Chicago, in the county of Cook. and ,State of Illi The object of the invention is the usual one, namely to provide a comparatively inexpensive safety paper which, when used for written or printed documents, cannot be altered without detection.
To the above-ends the invention consists in the matters hereinafter described and more particularly pointed out in the appended claim. In carrying out my invention I utilize any suitable paper, and upon this paper I apply a background such as lines, interlaced, wavy or stralght, stipple 'work, or a flat tint, and this background is applied in an ink readily fugitive to any usual chemical reagent. Preferably this background will be dark colored, but it should not be so dense 'as to interfere with the legibility of the documentary matter subsequently printed or Written upon the paper. Over this background I place a coating, which is preferably translucent but may be transparent. This coating is preferably made of any suitable sizing ent which renders it translucent. The fugitive lines of the background thus appear dlmly through the coating. The regular documentary matter is afterward printed or written on top of the coating in any of the usual ways.
By preparing the paper as described it will be, understood that the fugitive background is sandwiched between thebody of the sheet and the overlying protecting coat ing. Should the attempt be made to alter a document written or printed upon this paper by applying a chemical to remove the documentary ink, such chemical will penetrate thesizing and cause the fugitive background to disappear or change in appearance, and
inasmuch as the back round is applied directly to the body of the pa er beneath said coating it will be practical yimpossible to remove the documentary matter without disfiguring the sheet; Should the attempt be made to reproduce or replace the background after the original Writ ng or'printing has been removed, this will be practically impossible without detection, because it"is not only necessary to thorou hly remove the distorted or disfigured fugitive lines but they must be reproduced in exactly the same pattern or shade as theoriginal, and thereafter the peculiar quality, shade of coatin and finish exactly imitated "n covering the altered spot, in order that the paper may not disclose the tampering when viewed either by reflected or transmitted light.
The invention may, perhaps, be more ex:
actly understood by a description of one practical embodiment, illustrated in the accompanying drawing.
The drawing illustrates the face of an ordinary bank check.
In the drawing the series of closely spaced parallel lines covering the face of the check represent the background; these lines being made light to indicate that theyshow dimly through the superposed translucent sizing. The check illustrated was originally filled out for the sum of one hundred dollars, and by erasing the letter 0 in the word one and writin in the letters ni, as indicated at a, the word one becomes nine.- Then by simply changing the numeral 1 in 100 by the addition of the oval the amount becomes 900. The removed or defaced background covering the spot originally covered by the letter 0 discloses the alteration.
I claim as my invention:
, A safety paper consisting of a sheet of paper, a" coating of sizing partly charged with pigment to render it translucent, covering the face of the paper, and a background pattern of waterpioof ink fugitive to chemica reagents sandwiched between the front face of the paper and the translucent coating.
