TRANSFER AND PROCESS OF PREPARING AND APPLYING DESIGNS Filed Jan. 12, 1931 Patented Feb. 13, 1934 TRANSFER AND PROCESS OF PREPABIN AND APPLYING DESIGNS Frank Rubin, Wauwatooa, Wis. Application January 12, 1981. Serial No. 508.085 2 Claims. (Gail-33) This invention relates to improvements in transfers and process of preparing and applying designs.
The primary object of this invention is the production of special designs with great economy and convenience. In the practice of this invention no manufacturing machinery is necessa y. The economy is such that any room may be treated uniquely by, the application of an individual design thereto at a cost comparable to that now involved in the application of a conventional design.
More particularly stated, it is my purpose to provide a transfer which may be assembledeconomically upon a transparent or translucent base of some cheap material such as paraffin paper, from which the design may be removed freely for application to the surface to be decorated. It is my further purpose to provide a transfer which may be used as a mask to produce novel results economically in the decoration of a given surface.
I further propose to provide a novel transfer film which may be built up to any desired strength and thickness so that it may be han dled independently of backing material and transferred as desired from one transfer backing to another.
In the drawing:
Figure 1 shows a series of steps in the manufacture of a transfer embodying this invention.
Figure 2 shows a series of steps in the application of the transfer design to a. surface requiring decoration.
Figure 3 shows a special form of transfer embodying this invention.
Figure 4 shows transfers embodying this invention applied to a surface to be decorated to function thereon as a mask.
Figure 5 shows the mask partially removed to complete the decoration of the surface illustrated in Figure 4.
.Like parts are identified by the same reference characters throughout the several views.
One of the important features of the present invention resides in the particular transfer film which makes possible the use of parafiin paper as a backing material.- Other transfer agents heretofore known have notbeen adapted for use with paraflin paper either because they would not adhere thereto or because they adhered too tenaciously to enable the paper to be freed from the transfer without heat or solvents. It is desirable to use a transparent or at least a translucent backing material in order that the design backing material or support for the transfer is coated with a transparent carrier '7 to any desired thickness, according to the purpose for which the article is to be used. The carrier may be applied with a brush or, as shown in Figure 1, it may be applied by means of a roll 8 turning in a trough 9 containing a supply of the carrier fluid. The paper 6 is held to the surface of the applicator roll 8 by means of a coacting pressure roll 10.
The carrier preferably employed is a cheap mixing lacquer such as is obtainable from the Berry Varnish Company and other lacquer manufacturers and intended for use, mixed with shellac, by furniture makers. The utility of this kind of 78 lacquer is derived from its ability to dry almost immediately. More expensive lacquers dry slowly and tend to adhere too strongly to the paraffin paper. A lacquer of the proper character for the purposes of the present invention will evaporate 80 its low boiling point solvent alcohol and dry in a few seconds after being applied to the paper as shown in Figure 1. I prefer to mix with the lacquer some vegetable oil such as castor oil, China-wood oil or linseed oil, (castor oil preferred) in the proportion of about six ounces of oil to a gallon of lacquer. It is a film made-upv of successive applications of this quick drying fluid which is used as a carrier for the design to be transferred.
For convenience of illustration I have designated the coating 7 of lacquer-by dots in the drawing. It will be understood, however, that the carrier coating is highly transparent and substantially invisible unless a colored lacquer is used for 05 certain purposes hereinafter to be described. As a rule it is necessary to build up the carrier film by at least three applications of lacquer to the backing sheet of paraffin paper (if For special purposes where the film must be handled independently of the backing sheet a much greater number of applications of lacquer may be made. Eachapplication of lacquer will dry before the next coat is applied.
Upon the carrier film 7 I print, stencil or otherwise form the desired design in any number of operations. In Figure 1 I have shown the block shaped designs 11 applied in one operation, the complementary block shaped designs 12 applied in a further operation and a background coat 14 v110 2 applied in a final operation. The background pigment may obscure the color blocks 11 and 12 'ried thereby or to the carrying film which are thus made to appear only in dotted lines in the final view of Figure 1. It will, of course, be understood that any desired design may be lettered, printed or stenciled with ink, paint or any other pigment upon the lacquer carrier film 7, and it will also be obvious that the background coat 14 of pigment may be omitted when desired.
The completed transfer is flexible and may be tightly rolled without damage to the pigment car- '7. The carrying film is very tough and provides excellent support for the pigment comprising the design.
In order to use the transfer, it is only necessary to apply the surface 14 to a suitably adhesive surface to be decorated. The transfer may be applied on tacky varnish or shellac, or paint. In the alternative, the face 14 of the transfer may itself be treated with a suitable adhesive, such as rubber cement or varnish comprising a coating shown at 15 in Figure 2. The adhesive coating 15 is then rubbed smooth in contact with the surface to be decorated, and the paraffin paper is stripped from the carrier film 7, leaving the transfer in place on the surface to be decorated and exposed through the carrier film. The carrier film will be somewhat dull because of its contact with the parafiin, but it may be rubbed to a smooth transparent finish through wh ch the transfer deif it were not covered sign appears as clearly as by the film. Preferably the transfer and its protecting film, as well as the entire surface decorated with the transfer, are varnished after the application of the transfer.
The lower view in Figure 2 shows the operation of stripping off the parafiin paper to expose the carrier film. It will be noted that the design comprising blocks of pigment 11 and 12 is clearly visible through the film '2 Although the design illustrated is such that it does not indicate reversal, it will be observed that in fact the blocks of pigment are being viewed from the opposite side from which they are viewed in Figure 1. Thus it must be remembered that in applying any design to the carrier film in the course of the operations illustrated in Figure 1, the design must appear in the reflected image of the form in which it is ultimately to be transferred to the surface to be decorated. It is only the use of a very quick drying lacquer, as above noted, that makes it possible to strip the paraflin paper freely from the carrier film '7 in the manner just described.
By repeated coatings of lacquer the carrier film may be built up on the backing sheet 6 to a thickness and strength such that it may readily be handled independently of said sheet. An interesting application of this invention consists in thus rendering the carrier film self supporting and cutting it into letters, symbols or other designs, as shown at 16 in Figure 3. The self supporting film may then be used as a mask, a protective covering for some other design, or it may itself be applied to a surface to be decorated. I have found it convenient to use colored lacquer in the final coating operations in the formation of a film such as that used as a blank in the preparation of the letter 16. The shading in Figure 3 indicates color.
I have found that apiece of film'such as that of economical production and shown at 16 may be temporarily mounted upon any piece 17 of parafiin paper and may be applied to any adhesive surface. If the surface which is to receive the design 16 is not of itself adhesive, it may be rendered so by treating either the surface or the design 16 with alcohol, which renders the surface of the lacquer film tacky", thus causing the design 16 to adhere to the surface to which it is applied. This particular fea ture of the invention is useful in lettering glass doors or windows. The entire inscription to be placed on the door or window may be set up in advance by cutting out letters 16 of the proper size, and applying them in their proper order to the temporary supporting sheet 17. The adhesion of the film to the temporary supporting sheet is sufficiently light so that the characters may be rearranged at will, but the adhesion is sufficiently strong so that they will not accidentally become displaced. Through the use of a transfer of this type, even the most unskilled person can produce a lettering job equal to the work of the most skillful painter.
Another important use of this invention is in connection with masking operations as illustrated in Figures 4 and 5. Figure 4 shows two letters or characters applied to a surface 18 which is to be decorated. Each of the letters or characters may comprise a backing sheet 6 carrying a film 19 (Figure 5) in plain or decorated color (or merely transparent). Around the letters or characters is a border made up of a number of strips of backing sheets 6 to which a carrier film 7 and design has been applied in accordance with Figure 1.
. In Figure 5 the entire surface to bedecorated has been painted with a coating shown at 20. The backing strips 6 of the border and the letters or design are now removed to expose the plain or decorated carrier film. essentially a transfer operation, but because of the fact that the backing strips serve as masks for the transfer, a very clean cut piece of work results, and special effects are possible which could not readily be secured in any other way.
It will be obvious from the foregoing disclosure that Ihave provided a novel transfer susceptible use in a variety of new ways, and including, as one important factor, a carrier film and backing strip which are fiexible, transparent, mutually adherent and yet readily separable without the use of either heat I claim: 1. The method consists in forming a ing sheet, rendering and removing the backing sheet whereby to expose said film.
2. The method consists in applying a lacquer film to a paramn paper backing sheet, supporting by said film a coloring material visible therethrough, applying the color bearing film to the surface to be decorated, painting said surface and the expom backing sheet, and stripping off said backing sheettoexpose saidfilmand the coloring carried thereby.
The operation is of decorating a surface, which
