TRANSFER AND METHOD 0F MAKING THE SAME.

Application tiled June 28, 1926. Serial No. 119,039.

drawings illustrate the transfer conf structed in accordance with the provisions.

of this invention and in accordance with the new method.

Figure 2 is a View of that portion of the transfer that has been applied to the surface of an object.

Figure 3 is an enlarged broken vertical section on the line indicated by 33, Fig. 1,

3 the thickness of the various elements being exaggerated. p

Figure 4 is a view similar to Fig. 3, showing two of the elements in reverse order to the showing in Fig. 3.

5 Ordinary transfers or decalcomanias are produced by printing y specially prepared paper so that, when the paper is laid upon a smooth surface and dampened, said paper can beremoved, leav- U ing the printed matter upon Said surface. Lquell transfers are not practical for use 1n the marking of packages that are exposed to the weather and subjected to friction in handling', as printers ink soon becomes more 5 or less obliterated, and one of the principal objects of this invention is to provide a type of transfer which is not open to the foregoing objections. g

To make the transfers according to the 0 principles of this invention, a stencil or stencils are made on bolting cloth, as is Well understood in the art relating to the reroduction of colored designs by the use of cloth screens or stencils. One method of :5 making said stencils is described in detail in my copending application Serial No. 119,040 filed June 28, 1926.

If the transfer is to be of the reverse type,

as illustrated in Figs. 1 and 3, or, in other 0 words, of the type which is necessary to be inverted when transferring to the surface on which the design is to appear, and if any of the design is to appear in ink, suitable decalcomania paper is first printed in the usual inanner on a printing press to produce rality e with suitable ink upon a desired portion of the design as an ink coat on said paper. This ink coat is the first on the transfer but will be the last or undermost on the surface on which the design is to ultimately appear. Preferably, however, the ink employed is of. considerably greater body or consistency than that usually used. The printing is done on the prepared side of the decalcomania paper, the coating of said prepared side containing an adhesive material, such as is known to the trade as dextrine. y

The printed paper is then placed with the ink coat side uppermost beneath one ofv the cloth stencils mentioned above, and paint is forced through said stencil on top of the ink coat or impression. If more than one color of paint is to be applied, either a stencil for each color run will be used or the same stencil 'may -be employed repeatedly by dissolving or otherwise removing a portion of the blocked area from the stencil after each color run. The making of a pluof color runs either by the use of a sing stencil or by the use of a plurality of` stencils is well understood in the art relating to cloth stencil reproductions and, therefore, it is unnecessary to describe in vdetail herein how the preparation of these stencils is accomplished.

'The paint that is to form the last coatofthe transfer is specially prepared as there is mixed with said paint a special varnish, which may be made as follows: Take 100 pounds of the best grade of lime rosin and heat it to 450" F. Then sprinkle in the heated resin, 5 pounds of litharge, maintain? ing the heat at 450 F. for one hour or until the rosin and litharge are combined. Then add 14 gallons of heavy bodied linseed oil and raise the temperature of the mixture l to 500 F., and hold at this temperature for I now have a transfer embodying a printed coat and supcrposed thereon one or more paint coats or, if desired, the ink coat may be omitted so that the tansfer embodies` merely superposed paint coats.

If the decalconiania paper comprises a hase sheet and a tissue sheet on which the paint has heen laid. said tissue sheet will first he pulled from the hase sheet in a. manner well understood in the art relating to such paper, as `illustrated in Fig. 2.

To use. this form of transfer, the surface to which it is to he applied will he cleaned with water and, while said surface is damp, the paint side will he placed on the damp surface. thus causing the varnish in the last applied or undermost coat of paint to he come tacky or sticky. Awet sponge will he a plied to the hack of' the transfer to disso ve the coating on the paper and said paper will then he pulled off, leaving the Adesign in a. series of superposed paint or paint and ink coats on the article to which it has heen applied. Any surplus adhesive material that has come otf of the decalcomania paper with the paint may be washed oit and the paint will then remain an indefinite length of time.

If the transfer is of the slip-off type, as illustrated in Fig. 4, or, in other words, of a type in which the paper is slipped from between the paint coats and the surface on which the paint coats are to he applied, the operations described ahove of applying the ink and paint coats will he reversed so thatthe ink coat will he uppermost or the last applied and, furthermore` so that the paint having therein the varnish will constitute the lowermost coat or first applied.

To apply this slip-off type of transfer, the side of the paper not provided with paint, will he applied to the damp surface and` after the paper has remained a snilicient length of time to dissolve the prepared surface having thereon the ink and paint coats, the operator will place his finger on the design of the transfer and grasp one edge or Corner of the pape-r and slip the same from hcneath the paint coats so as to lcai'e the paint coats upon the article'to which said coats are to he applied.

It is to he understood that if the paint is to he applied to the decalcoma-nia paper to produce a reverse type of transfer, as in Figs. l and 3, the stencils will he placed bottoni face up on the paper so as to reverse the design on the paper in order that, when the design is applied to the surface that is to receive it, the design will appear unreversed, as illustrated in Fig. Q.

I claim:

1. The method of making transfers which consists in mixing together paintand a varnish that is Sticky after it is dried and then dampened with water, and forcing the mixture thus made through a cloth stencil onto the prepared side of decalconiania paper.

2. The method of making transfers which consists in printing with heavy printers ink upon the prepared side of decalcomania paper a portion of the design to be reproduced, drying said ink, mixing together paint and a varnish that is sticky after it is dried and then dampened with water, and forcing the mixture thus made through a cloth stencil having thereon another portion of the design and onto the decalcomania paper and at least partly overlying the. printed portion.

3. A transfer comprising decalcomania paper, and a design thereon having a coat of paint as a part thereof, the paint Coat hav ing in it a Varnish that is sticky when said coat is dampened with water.

4. A transfer con'iprising decalcomania paper. and a design thereon having a printed coat and a paint coat, the paint coat having in it a varnish that is sticky when said coat is dampened with water.
