LIGHT-SHADE.

Application led october 26, 1916. Serial No. 127,793.

To all lwhom it may concern.'

Be it known that I, MICHAEL RONAYNE, a citizen of the United States, residing in the city, county, and State of New York, have made certain new and usefulImprovements in Light-Shades, of which the following is a description, reference being had to the accompanying drawings.

This invention relates to improved construction of shade for inclosing lamps or other source of light. The object is to obtain a shade to produce the effect of tapestry, which presents an equally pleasingappearance whether illuminated by an interior light or not.

A principal feature of my invention consists in having the inclosed body of the shade made of metal sufficiently stiff to provide stability to its form and support a film of decorative coloring mattei' partly embedded in small perforations in the metal, so the whole device is translucent except for very small portions of the metal between the perforations.

In the drawings forming part hereof, Figure l is a perspective view of a shade embodying my invention, Fig. 2 is a vertical section on the line m--w and Fig. 3'is a portion of the body broken away to show the method of construction.

In lamp shades a desirable point is to combine pleasing effect with stability. Another desirable characteristic is to have the shade decorative when onlysubjected to eX- terior light.

My invention utilizes a thin film made up of plastic, translucent, coloring matter, which may be dispensed in the shape of'pleasing figures or designs as a surrounding -for an inclosed light. As a means for stifl'ening and holding the decorative film in position, I use a fibrous translucent material A, for a keeper or backing` and on this superimpose a thin sheet of metal B, provided with regular distanced openings C, quite close together, so there will be but litle metal to obstruct the light. The backing A may be of rice paper, or other similar translucent material, which is first joined to the metal by a layer of silicate of soda. The side of the backing A, which forms the inner side of the shade, is then covered with a thin coat of shellac.

The body of the shade is then ready to receive the decorative film F which is placed in position on the metal. zlhis may be in the form of decorative colors of a design on the outer face of the metal.

The film F, is of such consistency as to fiow readily when being deposited with the air brush but must not be so thin as to run when deposited. Preferably it is composed of la mixture of linseed oil to which is added a littledrier and various coloring matter so as to display the figures on the shade. rThe flat portion of the film on the outer surface of the shade and the thickened portions which lie in the perforations, harden as the coloring matter dries. The thicker portions of the film in the perforations which fasten or tie the flat portions of the film to the metal, also act so as to refract the light passing through the shade when it is illuminated on the interior and thereby enhance the effect, presenting to the eye of the beholder something like figured tapestry.

.It will be understood that the film of colorlng matter when deposited is prevented from passing through the shade by the translucent backing, which may be white, or of any desired body color. softening in effect on the light. The film is applied by `means of an air brush and stencils, the colors being blown on the face of the mctai, portions thereof being intimately and evenly deposited in the perforations, which will be thicker than the rest, but the whole film is joined up with them in the completion of the figures or design.

By using the prepared backing A I am enabled to deposit and hold the film of col ors in position and the light passing through their increased thickness at the perforations, shows up the design when light is used on the interior of the shade in a pleasing manner. But the film carryinnf the design of colors is continuous on the face of the metal so that when the light strikes the shade from the outside, any design thereon is stili presented to the eye as a completed picture.

It will be understood that the perforations in the metal are so close to each other that there is but little intervening metal, and the size of the holes in the metal are of such dimensions that they will retain, 'without danger of loosening, the thickened portions of the film contained therein. I have found in practice that the holes in the metal should be about one-twentieth of an inch in diameter, or about fifteen to the inch, including the metal between.

The shade may be made in various shapes and many styles of coloring or designs may be employed. In the style of shade shown in the drawing, yI preferably employ a retaining ring D at the base and another E at the top to which cross bars Gr are fastened for securing the shade in position, but other means may be employed for these purposes.

What I claim as my invention is:

1. A lamp shade for inclosing a source of light, comprising an -outer film of plastic ornamental coloring matter supported in position on a erforated metal body and n translucent inner lining portion secured thereto, substantially as shown and described.

2. In a lamp shade for surrounding a source of light i perforated metal body having on its interior side a translucent lining extending over the perforations in the metal and an outer inclosing continuous translucent :film supported by the metal body, sub` stantially as and for the purpose shown and described.

3. A lampshade for surrounding a source of light comprising a plastic film of translucent coloring matter supported on a body of perforated metal and an interiortranslucent lining secured to the metal body comv bined With suitable means for securing the same to a lamp or other source of light, substantially as and for the purpose shown and described.
