Description
UNITED STATES PATENT OFFIC 1 WILLIAM J OI-IN (ILAPI, OF NANTYGLO, COUNTY OF MONMOUTH, ENGLAND.
PREPARATION, do, OF PAPER FORCl-IECKS, NOTES, STAMPS, &c.
, SPECIFICATION forming part of Letters Patent No. 305,292, dated September 16, 1884.
Application filed April 23,1884. (N0 specimens.) Patented in England October 15, 1883, No. 4,905.
by declare that the following is a full, clear,.
and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
The invention has for its object improve.
ments in the treatment of paper for checks, notes, stamps, and other documents, in order to prevent fraud. For this purpose I saturate the paper, either in the process of inanufacture or afterward, with a solution of gallic and tannic acids, or gallo-tannic acid mixed with gum-acacia or other suitable gum and alum. The solution above described must be sufficiently fluid or watery to enable it to be readily taken up by the paper, and yet of sufficient strength to produce the effect desired. It will be found that a saturated solution of the acid' and alum, or a solution slightly weaker, combined with a small proportion of gum in solution, will answer the purpose. This treatment will make little change, if any, in the color of the paper, but will render it everywhere sensitive to the action of preparations of iron. In some cases I add to the acid solution a few drops of the preparation of iron, hereinafter referred to, in order to facilitate the action on the prepared paper of inks which are weak in the iron constituent.
In the event of it-sbeing desired to print. on the prepared paper in colors, then I add to the acid solution a proportion of some alkali,
which shall to a certain extent neutralize the acid, which latter is, however, left in sufiicient excess to answer the purposes of my invention.
Iprint and write 011 paper, prepared as above and afterward dried, with an ink or p reparation containing ferri-sesqnichloride or other similar preparations of iron in quantity sutficient to cause the writing and printing to pass entirely through the body of the paper, whereby, in the event of any portion of the writing on the check, note, stamp, or other document being obliterated, the printing will also be removed, and the color of the body of the check or other document so altered as to render the attempted alteration apparent. This will also be the effect when any attempt is made to remove the obliteratingmark from stamps and other documents. print on both sides of the check or other document, in order to increase the difficulty of alteration. I also prefer to glaze the back of the paper.
Having thus described the nature of my said invention and the mode in whichI carry the same into effect, I would have it understood that what I claim is- The preparation and treatment of paper for the purposes described, which consists in saturating it with a solution of gallic and tannic acids, or gallo-tannic acid mixed with gum and alum, and then printing and writing on such prepared paper with an ink or preparation containing ferri-sesquichloride or other similar preparations of iron, substantially as herein described, and for the purpose stated.
