IMPROVEMENT IN PROGESSES 0F TRANSFERRING PAPER PRINTS.

Specification forming part of Letters Patent No. 158,154, dated December 22, 1674; application filed September 26, 1874.

To all whom it may concern:

onto Oil-Cloth,IVood, Glass, &c., of which the following is a full, clear, and exact description This invention relates to that class of processes employed for transferring paper prints onto wood, glass, &c., and usually accomplished by treating the picture with a chemical mixture to effect a separation between the paper and the ink, and then, after pasting the print onto the surface to be ornamented by the picture, removing the paper while damp by rubbing, the ink remaining attached to the surface. In the practice of this art according to the modes and by the use of the means heretofore known, very considerable time, often several days, was consumed in the transfer of a picture, and it could only be successfully done by an expert. My invention provides a method and means which enable any person of ordinary intelligence to thus transfer paper prints in a very short space of time, and it consists principally in soaking such prints for a few hours in diluted sulphuric acid, for the twofold purpose of separating the ink from the paper and to reduce the paper to a rotten condition, so that it may be the more easily removed.

In practicing my invention I soak the paper print for a few hours in diluted sulphuric acid, about one-half acid and one-half water. The

print is then removed, and reduced from a wet to a damp condition by taking up the surplus moisture with blotting-paper. The surface to which the picture is to be transferred is covered, to the size of the picture, with colorless varnish, and the damp print pasted on it with its face to such varnished surface, light pressure with a towel or cotton cloth being applied to its back to effect a thorough adhesion. The paper is then immediately rubbed ofi' in a careful manner, leaving the ink of the picture attached to the varnished surface, which may subsequently be again varnished or enameled to permanently protect the picture. The most distinguishing feature of my invention consists in the soaking of the print in a diluted sulphuricacid bath as a preliminary step. This, so far as I am aware, is entirely new, and wholly different both in purpose and result, so far as the principal action is concerned, from merely cleansing the picture by means of a waterbath slightly acidulated by sulphuric, muriatic, or other similar acids, which has heretofore been sometimes practiced as a secondary step in the pictures.

What I claim as my invention, and desire to secure by Letters Patent, is a The herein-described process of transferrii paper prints-that is to say, first soaking the} print in a diluted sulphuric-acid bath, thenl applying it in a damp condition to a freshl varnished surface to be ornamented, and the-in, immediately removing the paper by rubbing,, all substantially as specified.

In testimony whereof I have signed my, name to the foregoing specification in the, presence of two subscribing witnesses.
