Application filed August 22, 1923, Serial No. 658,702,- and in Great Britain September-'26, 1922'.

My invention relates in general to transfers, such as are employed 1n decorations and for the fixing on various surfaces of designs or pictures for ornaments, advertisements, or otherwise, and to a process of manufacturing same.

In the manufacture of transfers it has heretofore been customary to print the transferable medium or design by lithographic mechanism or some other analogous apparatus. In order to transfer the transferable medium or design from the transfer pro er to a desired surface, it was necessary to rst cover the medium or design with an adhesive substance in order to cause it to adhere to the desired surface. In most cases the transfer paper, on which the transferable medium for designs was printed, was provided with a thin coating of fixative such as gelatine which was usually diffused completely overthe surface of the transfer paper. By moistening the coating of gelatine, it was possible 'to very easily bring the transfer paper away from the surface to which the transfer design was applied.

Now the application of the adhcsivesubstance to the transferable medium necessitated another operation in the process of manufacturing the transfer. 'Then again, in applying the fixative to the transfer in order to cause same to be applied to a desired surface, quite frequently theedges of the transferable design became disturbed or messed up with the fixative, thereby deleteriously affecting the transfer design. 7

An object of the present invention is to provide an improved transfer equipped with a tough, hard, firm and homogeneous transfer medium, the hard surface of which s'e-' cures exceptional wearing qualities.

Another object of the invention is to pro= vide an improved process for manufacturing transfers of the above character with a minimum number of operations and as economically as practical.

Another object of the invention is to eliminate the necessity of employing a fixative such as an adhesive substance to cause the transferable medium to adhere to a desired surface.

Still another object of the invention is to provide a transfer in which the transferable medium itself will readily adhere-to a desired surface upon 'moistening same with a suitable solvent. A further ob'ect of the invention is to provide a trans er in which the colors are preserved from the action of the air.

A still furtherobject of the invention is to provide a transferable medium equipped with a protective coating of translucent matter.

To these'ends I provide a transfer comprising a transferable medium consisting of colors dissolved and suspendedin a collodion or cellulose medium and applied to transfer paper. through a stencil or stencils, preferably by the means of a spray. I also provide for first applying to the transfer paperv when ailixed a complete covering of transparent cellulose.

Other objects and advantages of the present invention will more fully appear from the following detailed description taken in connection with the accompanying drawings which illustrate one embodiment thereof, and in which:

Fig. 1 is aview of a sheet of transfer paper on which a transfer design is to be sprayed;

Fig. 2 is a view showing a stencil placed over the sheet of transfer paper in a position to receive the protective coating of cellulose medium; I

Fig. 3 is a view of the transfer paper after the first coating of cellulose medium has been applied thereto, the stencil being removed to clearly show the contour'of the design;

Fig. 4 is a view similar to Fig. 3 with the stencil placed back on the transfer paper ready to receive the solution of cellulose medium and coloring matter; and

Fig. 5 is a view of the finished transfer- It is to be understood, however, that any equivalent of transfer paper may be used and that if desired the coating of gelatine may be omitted entirely.

In Fig. 2 I have shown a stencil 11, superimposed on the transfer sheet 10. The stencil 11 may have an suitable desi figure, or an other form t at may be desired. Obvio y, although only one stencil 1s shown in this part cular embodiment of the 1nvention, several stencils may be employed particularly-where more than one color is to be used! The stencil 11, shown in Fig. 2, 18 provided with an opening 12 having the contour of a flower. r The next step in the process is to spray a diaphanic or translucent material, such as transparent celluloid, through the opening 12 of the stencil 11 onto the paper 10. Tlus transparent celluloid, upon hardening, forms a protective covering 9 for the transferable medium, as will be explained hereinafter The transferable medium, embodied with the features of my invention, is preferably made by dissolving or suspending in a collodion or cellulose medium the desirable coloring matter. This solution is then sprayed by any suitable means through the opening 12 of the stencil 11 on top of the coating 9 of transparent celluloid, forming the film 8 or in other words, the transferable medlum or design itself. Upon the film 8 of coloring matter and cellulose or collodion medium hardening into a firm character, the stencil 11 is removed and the transfer proper is in a condition .to be applied to any desired surface.

Furthermore, I have found by simply softening the transferable medium or filmr8 of coloring matter, collodion, or cellulose medium, with a suitable solvent, such as amyl acetate, that the transferable medium 8 may be affixed to practically any surface with facility and without the necessity of employing the usual fixative or adhesive substance. V

A volatilesolvent of the character of amyl acetate will be absorbed by that portion which is to be transferred and if a short interval of time-is allowed-to elapse before the transferable medium is applied to the article or surface, will evaporate from that part of the transfer paper to which it may have been accidentally applied, leaving it practically dry, with the result that the surface on which the transfer is being afiixed and which comes in contact with the transfer paper at the edges of the design, will not be disturbed or messed up with the fixative as usually happens in-ordinary methods of aflixing transfers.

- Now I desire it to be understood'that since the colors are embedded in the cellulose medium, they will befp'reserved from the ac-' tionof the air, but I av found it desirable in some cases to apply the previously mentioned protective coating of transparent celluloid 9, thereby greatly minimizing the material, such ascelluloid, may be used for transparent advertisements, or the like, when affixed to glass, or some analogous transparent material. I

Owing to the toughness and the firm, homogeneous character of the collodion medium or cellulose medium, large designs for mural decoration, and the like, may be manipulated, which is not practical in the case of the ordinary commercial lithographic transfer.

I also desire it understood that in. using the term solution. in the appended claims, I have reference to itsgeneral rather than its specific chemical meaning. I. intend that this term be construed broad enough to include both true and colloidal solutions. That is to say, the coloring matter need not be dissolved in the cellulose preparation or medium, it may be merely in a state of suspension or emulsification therein. Furthermore, by the term cellulose medium I have reference to both collodion and cellulose matter, inasmuch as one of the constituents of collodion is gun cotton which is a' form of cellulose and hence collodion may 'be'properly termed broadly a cellulose medium.

Without further elucidation the foregoing is thought to fully explain my invention so that others skilled in the art may, by applying current knowledge, readily adapt the same for use under various conditions of service. As is well known, the present invention should not be limited by the above specific embodiment of the invention, but

only in so far as defined by the spirit and scope of the appended claims.

I claim:

1. A transfer sheet comprising a base sheet, a coating of cellulose material applied thereto and a second coating of cellulose material and coloring matter applied upon the first coating.

2. A transfer sheet comprising a base sheet, a film of adhesive matter thereon, a coating of cellulose materialapplied upon the said film, and a coating of cellulose material and coloring matter appliedsupon the first mentioned coating.

3. A transfer sheet comprising a base sheet, a film of gelatinous matter thereon, a coating of cellulose material applied upon the said film and a coating-of cellulose material and coloring matterapplied upon the first mentioned coatingflzhe said coatings being of such character as to adhere to- 'gether and being adapted upon being moistened with a suitable solvent to adhere to a desired object.

4. The process of manufacturing transfer designs which consists in making a solution of only cellulose medium .an coloring matter, applying a film of the said solution to a base sheet and allowing it to harden into a firm homo eneous film, and subsequently causing t c said film to adhere to a desired object.

5. The process of manufacturing transfer 7 designs which consists in making a solution of only cellulose medium and coloring matter, applyin a film of the said solution to a base s eet, allowing the said film the said film to adhere to a desired object.

In witness whereof, I hereunto subscribe my name this 7th day of August, 1923.

WILLIAM T. DONE.
