T0 (tZZ whom 11mg} concern;

Be it known that I, J OHN BAYNES, a subject of the Queen of Great Britain, and a resident of 'Wcstchcster county, New York State, United States of America, have invented certain new and useful Improvements in Printinglransfer Processes, of which the following is a specification. I

My invention relates to improvements in ornameutiug various articles, or to producing etched or engraved outlines, figures, &o., upon the surface of any article; and it consists in the method, substantially as hereinafter set forth, whereby such ornamentation may be produced, and in whatl have termed a printing'transfer process.

'While my process may be carried out in various ways and by the use of various materials producing various results, I will now describe one way which I have found advantageous, and which will serve to illustrate my invention. I take a sheet of paper, for instance, and cover it evenly, back and front, with any material easily soluble in water or other substance, and I have found dextrine and glyoeriue, gelatinc, and the like good materials. \Vhen this is dry, I coat one side of the covered paper with an acid-resist that is sensitive to the action of light. I then print on this sensitive resist with an ink that does not become insoluble for some time*saytwent-yfour hours-and the printing may be effected by the use of blocks, lithographic stones, steel plates, &c., in any of the ordinary presses. The paper thus printed is then exposed to the act-ion oflight for a sufficient time, the ink acting as a negative and to keep the resist under it from changing or drying. Then the parts of the resist not covered by the ink have been suflicieutly exposed to become changed and insoluble, I wash the paper in some liquid in which the original coating is insoluble, and in which the resist, unaffected by light and covered by the ink, is soluble, as turpentine, and thereby remove the resist and the ink over it from the parts printed, leaving the coating of dextrine, Sea, on the sheet of paper exposed at the parts corresponding to the pattern of the ornamentation. I then cover the whole face of the paper, as well as the metal or other object to be decorated,'with a resist or varnish that is insoluble in water, or in any substance in which the original coating on the paper is soluble, and when this varnish becomes tack y I place the paper with the resist-coating face downward upon the metal or other object, as aroller, for example, and thoroughly rub or otherwise get uniform contact, free from air-bubbles, between the two surfaces. The whole is then putin water, if dextrine or gelatine is used, or in some other solvent for the original coating, and the dextrine is first dissolved and removed from the back of the paper. Then the paper is penetrated by the water and the dextrine on the face of the paper is dissolved,when the paper is removed, leaving the resist pattern secured to the article.

The varnish may be applied to the article to be ornamented only; but I have found that the adhesion under such circumstances is not so perfect, and I prefer to coat both the pattern and the object as above described. The surface of the object is then wiped or sponged with turpentine, which will remove all soluble portions of the varnish or resist, leaving the article covered with a clear pattern of the desired ornamentation,when it ma y be treated to the ordinary etching or other process to produce the ornamentation, and the pattern may be afterward removed by any suitable means, as is well understood.

Sometimes I have found it desirable to first coat the paper with an oil-varnish or other substance soluble in oil, and to then coat this with a gelatine bichromate resist, and to then print, as above described. The gelatiue resist is then exposed to the action of light and after developing it in water it is caused to adhere to the object to be ornamented either by water or by a varnish insoluble in the some oil as the soluble coating on the paper. It can then be treated with turpentine or something that will dissolve the oil-varnish on the paper and afterward etched. The pattern may be used as a stencil to brush out or dissolve in any other way some other object, as paint, that has been previously applied to the object to be ornamented.

The process may be varied somewhat and still produce the same effect-as, for instance, after the paper has been covered with the coating of sensitive material and printed and exposed to the action of light, but before developed, it mayinstead be attached directly to the metal or otherobject while the ink is upon' it. Then by dissolving the varnish and removing the paper the sensitive resist may be developed directly upon the object itself and the soluble parts and the ink removed, lea"- ing the pattern adhering, as before.

In order that the process may be better understood, reference is made to the accompanying drawings, forming part of this specification, in which Figure 1 shows on an enlarged scale the sheet of paper a, having a coating, 12 b,on each side thereof of dextrine, gelatine, or the like. Fig. 2 is a similar view showing the coated paper with a layer of sensitive acid-resist on one side thereof, the resist being represented by dotted lines. Fig. 3 is a perspective view of a sheet of paper coated on both sides and covered with an acid-resist and having the ornamentation or pattern I) printed thereon in ink in the manner described. Fig. 4 is a sectional view showing the paper a,having a coating on each side and the resist c on one side after the same has been exposed to the action of light and the parts covered with ink,cZ, corresponding to the pattern, having been removed by washing or otherwise. Fig. 5 is a similar View showing the pattern-sheet of Fig. 4 covered with a layer of adhesivematerial or varnish, c. Fig. 6 is a perspective view of a roller, A, covered with a similar adhesive varnish, c. Fig. 7 is a sectional view of the roller A covered with a coating of varnish, e, and having the pattern shown'in Fig. 5 applied thereto. Fig. 8 represents the same roller after the coatings and paper have been removed, leaving the hardened resist upon the surface of the roller and the portions corresponding to the pattern covered with the ad hesive varnish. Fig. 9 shows a similar view with the adhesive varnish removed from the cylinder at the portions corresponding with the pattern of the ornamentation, the roller being in condition'to be etched or otherwise operated upon to produce the ornamentation;

and Fig. 10 is a perspective view of the ornamented roller.

From the above my improved process will be readily understood, and it will be seen that designs or patterns of the most intricate character, as well as the simple pattern illustrated in thedrawings, may be readily applied to the object to be ornamented and reproduced in an exact similitude of the original copy, and this may be done without the expenditure of skilled labor, requiring only a careful manipulation of the various steps of the process set forth.

What I claim is 1. The method, substantially as hereinbefore described, of ornamenting articles, which consists in coating a transfer-sheet with a sensitive acid-resist, printing the pattern on said resist in ink after exposure, removing the portions of the resist corresponding to the pat tern, and transferring the remaining portions to the-surface of the article to beornamented.

2. The method, substantially as hereinbefore described, of ornamenting articles, which consists in coating a transfer-sheet, applying the sensitive acid-resist to one surface thereof, producing the pattern on the surface of the resist in ink, exposing the removing the portions thereof the ink, applying said pattern to the object to be ornamented, and removing the transfersheet and coating therefrom and subjecting the article to an etching process.

3. The method, substantially as hereinbe fore described, of ornamenting articles, which consists in covering a sheet of paper with a coating whichis soluble in water, applying a sensitive acid-resist thereto, printing the desired pattern or ornamentation upon the resist in ink, exposing the resist to light and removing the portions covered by the ink, applying an adhesive coating to the patternshect thus formed and securing it to the article to be ornamented, removing the pattern sheet from the hardened resist, and etching the article at the exposed parts to produce the pattern.

4. An adhesive negative transfer-sheet hav' ings its coated surface covered with a sensitive acid-resist and the pattern of the ornamentation printed directly thereon'in ink, substantially as described.

I11 testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
