IMPROVEMENT IN SAFETY-PAPERS.

Specilication forming part of Letters Patent No. 167,223, dated August 31, 1875 yapplication filed July 8, 1875 To all-whom it may concern:

Be it known that I, GEO. W. CASILEAR, of Washington, in the county of l/Vashington and District of Columbia, have invented certain new and useful Improvements in Safety- Paper; and I do hereby declare thatV the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification.

My invention relates to a novel means for preventing the alteration or re-use of revenue and postage stamps, or the raising or otherwise changing the character or value of any evidence of value printed on paper, or counterfeiting the same by transfer, photography, photolithography, &c.

With these objects in view, my invention consists in a paper of ordinary structure or ingredients, with its top surface covered with a woven fabric, or with a warp of fragile open texture and meshes, or the warp secured to and embedded in the paper body or foundation during the process of manufacture of the paper, or afterward by uniting the two under pressure; the natural moisture of the pulp in the manufacture ofthe paper, or the dampening slightly of the sheet after manufacture, serving to sufficiently meisten and soften the starch or gluten in the textile covering, or the sizing of the paper, to induce to a perfect union of the fabric and paper when pressed and dried and calendered. The paper thus prepared with a textile-fabric face or upper surface may be readily printed upon either by type or plate, and may also be written upon with a pen; and any effort made to erase any of the printing or writing from the face of the paper by the use of a knife will necessarily result in the destruction of the lace-work or fabric covering, for the ink, being absorbed by the fibers of the fabric, can only be thoroughly erased by completely cutting away such portions, and as the weft and Warp (or the warp, if preferable) give character to the face of the paper, the absence thereof at any particular place would be readily recognized, and suspicion awakened, resulting in the certain detection of any ei'ort at tampering. Another resulting benet from my invention is the fact that by using colored textile fabrics a surface tint77 may be given the paper without the the print fac-simile by photography or photo-- lithography. It will also be impossible to extract the color, or transfer to a plate, or erase any ligure or evidence of value for any of the purposes of counterfeiting or altera- `tion by any liquid or acid treatment, for the reason that the surface covering of lace or other woven fabric or warp readily and quickly absorbs, by capillary attraction, any uid coming in contact with it, and draws away from its paper foundation to a greater or less extent, according to the treatment it receives, but in every case to such an extent as to magnify and make patent any effort at erasure or alteration.

My invention is designed more particularly for internalrevenue and postage stamps, checks, bonds, &c., though, of course, it may be used to great advantage elsewhere; and for a full and more perfect description of the advantages attending the use of my improved paper for revenue stamps, Snc., I refer to another application filed myself and WV. C.

Mclntire, jointly, for improved revenue and postage stamp.

In the drawing accompanying this specilication, Figure l represents a live-pound snuffstamp made orprinted upon ordinary paper in black, and Fig. 2 represents a similar stamp printed upon paper embodying the elements of my invention, the broken lines crossing each other at right angles representing a woven fabric of pink or other desirable color, secured in the manner hereinbefore described to the paper body, (the paper and textile cover being both .exposed to view,) and afterward printed upon, the impression necessarily being partly on paper and partly on spun fiber; and Fig. 3 is a cross-section, on an enlarged scale at m a: of Fig. 2, showing the woven or other fabric embedded in the surface of the paper.

Having described my invention and its advantages so that those skilled may make and use the same, and not wishing to be understood, as claiming, broadly, a paper and woven fabric combined,

What I claim as new, and desire te' secure i View, and he capable of separation, in the by Letters Patent', is-
