'whic form a part of this s eciiication.

My invention has for its 0 ject to produce a simple and eficient method of making flexible, translucent decorative panels or panels carrying inscriptions or legend's;

' such panels being adapted to be used instead of glass.

In accordance with my invention 1 make use of a fine mesh wire screen or other perforated, flexible sheet to form the body of the panel, mount a colored translucent decalcomania film thereon, and cover the whole with a translucent material which enters into the interstices in the screen.

In the accompanying drawing 1 have illustrated a panel under the difierent conditions which may be encountered during the process of making the same: Figure 1 being a cross section on an exaggerated scale of a portion of a wire screen after a decalcomania film has been pressed thereon; Fig.

2being a view similar to Fig. 1, showing a defect which often occurs .upon the removal of the pressure from the film; Fig. 3 being a view similar to Figs. 1 and 2 il ustrating the panel shown in Fig. 9 after the application of the adhesive coating; and Fig. l bein a side elevation of a fragment of the compdeted panel on an enlarged scale.

My invention can best be described by referring to the drawing.

ll take an ordinary fine mesh wire screen, indicated at min the drawiurwand mount upon one Side thereoi a colored, translucent, decalcornania film indicated at I). Wnen the film is mounted, the transfer sheet is placed between the screen and a soft pad which will yield under pressureand enter the interstices of the screen, carrying portions of the film with it and producin in the film numerous cup-like sections w ich extend into the spaces between the wires, the transfer sheet being first made wet by dipping it in water, pouring water over,- it,

. some hard object.

or in eny other usuel mannen lln Fig. 1 l have illustrated three wires (1, a and a and two cup-like film sections 6 and b which extend to the spaces between the wires. The member 6, it will be seen, followsthe curvature of the wires end therefore adheres closely thereto. Another similar section, which may be the section b, for so e reason or other may not be pressed as snug'v between the wires as the section 6. Therefore, when the pressure upon-the film is removed, and all the stretched portions of the til-m are under a tension tending to restore them to their normal flat condition, the section b, which is insecurely held, will flatten out as indicated at b in F ig. 2. lit is evident that where some of the cup like portions retain their shape while others flatten out, an uneven irregular surface is prwuced which distorts the decoration and detracts greatlyirom the appearance of the penel. Furthermore if the panel wereused in this form the film would soon dry and crack and even before this happened itmight be injured by coming in contact with l have found that the iilm may. be protected against injury through contact with hard objects and prevented from cracking by covering the panel with some translucent adhesive substance such as varnish or shellac, the adhesive substance also filling the interstices in the screen about the film. The varnish or shellac may be applied in various ways but-l have found that a peculiar advantage re-' sults from dipping the screen into the varnish or shellac after the film has been applied and then permitting the excess of varnish or shellac to drip from the panel. When the panel is dipped the varnish enters into the spaces between the wires and comes in contact with both sides of the film. W hen the panel is lifted from. the bath the excess of varnish or shellac begins to run down the same and tends to draw out of the interstices the small bodies which have collected therein. Now there will be consid-" erable body of varnish or shellac between the wires a and a and engitge with the film section 5 The film at t is oint, having reviously been stretched, an also because it is naturally thin and flexible, yields to the pull upon the adhesive body back of it and is drawn inwardly into substantially its original on -like shape as indicated at b in Fig. 1; t e varnish or shellac being sulfirotted Dec. a, rare.

ciently viscouseto transmit the pull to the film. After the film has been drawn in far enough to make its resistance greater than the tensile strength of the body of varnish or shellac behind the same, further movement thereof will cease and the varnish or shellac will begin to set and harden so as to hold the film in the position into which it has been drawn. The condition of the parts after the excess of varnish or shellac has been allowed to run off of the panel is illustrated in Fig. 3, there being a layer of shellac or varnish G on the front side of the film and the second layer C extending along the rear sideand filling" the spaces between the wires. v

A panel made in accordance with the present invention will be strong, light and flex- .ible;-it will have the appearance of pebbled glass under transmitted light; and the translucent colored subject will appear in a beau-t tiful glow, the light being uniformly dis- 'tributed by reason of the uniformity in the surface of the film. Furthermore the panel may be washed in the same way as glass so that it may be kept bright and clean.

What I claim is: f' 1. The procem of making a decorate translucent panel which consists in pressing a 'decalcomania film in a dampened condi-v tion upon a wire screen so as to cause the film to stretch into cuplike sections extending into the interstices of the screen, and

then applying an excess of varnish to the.

screen before the film dries and allowing the surplus of varnish to run ofi.

2. The processof making a decorated translucent panel which consists in pressing a decalcomania film in a dampened condition upon a wire screen so asto causethe film to stretch into cup-like sections extending into the interstices of the screen, and then dipv ping the screen in varnish or shellac and holding it so as to permit the excess of varnish or-shellac to run ofi'.

3. The process of making a decorated translucent panel which consists in pressing a decalcomania film upon a wire screen so as to cause the film to stretch into cup-like sections extending between the wires of the screen, and then dipping the screen in varnish or shellac before the film'becomes hard and dry and permitting the excess of varnish or shellac to run off so as to restore the cup-like configurations of any sections.
