This invention is a method of applying decoration to glass and while adapted for use upon glass generally is particularly intended to be used in the decoration of mir- 5 rors.

0 become unsightly. The most common practice in this connect-ion is to cover the mirrors with fine gauze or netting, although in many instances, mirrors have been covered with a coating of powdered chalk. applied wet and permitted to dry, so as to have a frosted elfect. According to either of these former modes of procedure, the resulting appearance of the mirror is less attractive than if it were left uncovered and in its natural state.

The object of the present invention is to properly cover the face of the mirror or other sheet of glass in a manner to enhance its appearance and render the mirror surface susceptible of ornate advertising.

An important factor is the present invention resides in the fact that the covering which I employ cannot possibly do any damage to the surface of the glass and while apparently permanent in its nature may be readily removed by merely rubbing off the cover ing with a soft, preferably moist, cloth. The materials used for the coating and decoration are such that they will not scratch the glass, but the bond between the glass and its covering and decoration will be such as to maintain the decoration in place until it is manually removed. Ornate decoration, ad-

vertising, lettering, and the use of words,

characters or symbols may be applied to the glass surface in a thoroughly practical 1na11- ner and may be removed with ease and expedition when desired."

Speaking generally, the method of this i11- vention consists in first-applying to the sur- 1931. Serial No. 534,930.

face of the glass a solution of soap powder,

epsom salts or similar material in wet form.

to give very satisfactory results for this socalled ground coat. After the ground coat has dried, the decoration is applied and for the application of such decoration, I preferably employ water colors or show card colors with which I mix prior to application a portion of the material ofwhich the ground coat is constituted and I apply the desired decoration with thismixture' directly to the ground coat by stencil orbrush application as may bemost convenient under the circumstances. The resulting product to which the present invention is also directed comprises a sheet of glass, the face of which is. covered with a ground coat on which is super-' imposed decorative matter comprising the. desired coloring material preferably including as a constituent material from which the ground coat is formed.

Features of the invention, other than those adverted to, will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawlng. 1

The accompanying drawing lllustrates one practical embodiment ofthe invention, but

the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a front view of a mirror'emboclying the present invention.

Figure 2 is a vertical section through the mirror shown in Figure 1.

Referring to the drawing, 1 designates a sheet of glass, the back of which may be silvered to form amirror. The glass is shown as mounted in a frame 2 in which it is held in place by means'of brads 3. This is conventional mirror construction and forms no part of the present invention other than it provides a suitable backing for the coatings to be applied thereto as hereinafter described.

In practicing the present invention on a mirror of this conventional form, I first apply 7 to the face of the glass 1 a so-called ground coat. This ground coat may comprise epsom salts, soap powder or any other suitable material which may be applied in liquid form and which will dry into a white thin film, adhering to the glass with suflicient tenacity to preclude it from falling off or blowing off. but which will nevertheless be sufiiciently easily removable that it can be taken off with a soft cloth. The material used for this ground coat should be lacking in grit. and should not be of such abrasive character that it will scratch the mirror during removal. It is preferably put on in its naturalwhite form, although if desired it may be tinted prior to application without departing from the invention.

WVhen any of the materials to which I have referred are applied to the surface of the glass in the form of a solution, the water of said solution quickly evaporates or dries off leaving deposited upon the surface of the glass the solid materials thereof in the form of a powdery coating which, as stated, has slight adhesion with the surface of the glass. This adhesion as stated will preclude inadvertent displacement of the powdery material, but is of such slight character that the material is readily rubbed'otfwith a soft cloth when it is desired to remove the same.

It has heretofore been suggested to affix materials to glass surfaces by means of various gums, varnishes, etc., which dry into afirm'permanent coating which can only be removed with great difliculty and generally require the use of suitable solvents of a character which will damage wood finishes such as are frequently used onmirror frames. The present invention should not be confused with permanent coatings, such as those to which I have referred as the powdery protective coating of this invention is in no sense permanent and in contradistinction to prior practice employing gums and varnishes, the coating of this invention may be readily removed when desired.

I have found that a Very satisfactory ground coat may be made by wetting bon ami and applying the same with a soft cloth, brush or sponge to the face of the glass 1. Through the medium of application, the nature of the ground coat may be varied somewhat so as to give a cracked ice, stippled or mottled effect when the ground coat dries. Upon drying the ground coat is in the form of a relatively thin film which completely covers the surface of the glass and adheres thereto with suflicient adhesion to form a proper background for the decorative matter to be applied thereto.

After the ground coat is thoroughly dried, I next superimposeupon this ground coat the desired ornamentation which may partake of different forms and may be in the nature of advertising matter or may convey seasons greetings. This decorative matter be it in the nature of letter, word, symbol or pictoral illustration may be applied by brush or stencil or in any other suitable way, but I preferably sketch a layout on the ground coat and then apply the decoration by way of a brush through the use of water color or showcard colors and these colors are applied directly to the ground coat. The color should be applied in a condition wherein they will be as dry as possible, so as not to unduly loosen the ground coat from the glass, and I have found that the application of these colors will be materially facilitated if into the color is mixed a portion of the material constituting the ground coat. For example, in applying the water color some bon ami is mixed into the water color and onlv so much water is required as to make the color workable. Instead of using water colors I may, however, use bronze, gilt or similar powders in the solution of mucilage or the like as a binder and vehicle. Vith this solution may be mixed some of the ma terial of the ground coat.

I call particular attention to the fact that;

the ground coat is interposed between actual decorative subject matter and the face of the mirror and forms a protective covering so that during the application of the color or other decoration scratching of the mirror cannot result. Furthermore, colors'of certain of the kinds referred to would adhere to the surface of the glass so tenaciously that it would be extremely difiicult to remove them, this being particularly the case with metallic powders applied with mucilage. With the interposed ground coat, however, the decorative subject matter does not adhere to the material at all except through the intermediarv of the ground coat and consequently the whole can be readily removed when desired by the use of a soft, preferably moist. cloth.

In the drawing, the ground coat is designated by the reference character at while the decorative matter is indicated by the reference numeral The present invention fulfills a long felt want in the art to which it relates. It provides for the utilization of a mirror or other glass surface as an advertising space and renders decorative and useful surfaces which have heretofore been considered impractical for advertising purposes. It provides for the application of desirable indicia to glass surfaces without tenacious adhesion thereto and in a manner which will permit the subject matter to be readily removed when desired without scratching or in anywise detrimentally; affecting the surface to which it had been applied. It provides, moreover,

that mirror surfaces may be properly and efficiently covered during the summer season by decorative subject matter where heretofore nothing of this sort was known or reco nized.

The foregoing detailed description sets forth the invention in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claims.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. As a new article of manufacture, a sheet of glass, one face of which is covered by a film-like coating of soap powder whereby said protective coating is readily removable, and decorative matter applied in film form to the protective coating, said film of decorathe matter embodying as a constituent the same material embodied in the protective coating.

2. As a new article of manufacture, a sheet of glass, the normally exposed face'of which is provided with a powdery film-like protective coating, and decorative matter applied in film form to the protective coating, said film of decorative matter embodying as a constituent the same material as embodied in the protective coating.

As a new article of manufacture, a sheet of glass, the normally exposed face of which is provided with a powdery film-like protective coating, and decorative matter applied in film form to the protective coatin 4. As a new article of manufacture, a sheet of glass, the normally exposed face of which is covered by a powdery film-like coating of opaque material adapt-ed to be readily removable without the employment of solvents, and decorative matter applied in film form to said protective coating.

5. The herein described method of applying decoration to glass surfaces, which consists in first applying to the normally exposed surface of the glass a solution of bon ami, thereupon permitting said solution to dry to form over the surface of the glass a ground coat which is readily removable, and thereupon superimposing decorative subject matter on the ground coat.

6. The herein described method of applying decoration to glass surfaces, which consists in applying to the normally exposed surface of the glass a wet film-like coating of material, which when dried will leave a powdery residue, permitting the said film to dry to form over the surface of the glass a readily removable powdery ground coating, and thereupon superimposing upon said ground coating decorative subject matter.
