No. 517,364. Patented Mar. 27, 1894 UNITED STATES PATENT OFFICE.

WILLIAM SHAW, HENRY SHAW, AND OSEPH SHAW, OF JACKSONVILLE, FLORIDA.

SKYLIGHT FOR PHOTOGRAPHIC GALLERIES.

SPECIFICATION forming part of Letters Patent No. 517,364, dated March 27, 1894.

Application filed June 14, 1893. Seriallio. 477,59'7- (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM SHAW, HENRY SHAW, and JOSEPH SHAW, citizens of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented a new and useful Photographers Sun-Shade, of which the following is a specification.

Our invention relates to improvements in lights for operating rooms of photographic galleries, and the objects in view are to provide means for softening and toning down the sunlight that enters the room; to avoid the necessity of employing for such purposes numerous curtains or shades.

Heretofore it has been customary to employ under the glass roof numerous curtains or shades which necessitated as many or more strings for operating thesame, and disadvantages have arisen from the fact that the shades would Wear, become torn, the strings broken, &c.

For our invention, however, we propose to avoid the employment of these shades, and, as before stated, soften the light through other means.

Referring to the drawings-Figure l is a perspective View of a roof, the same being provided with our invention. Fig. 2 is a vertical transverse sectional view of the device.

Like numerals of reference indicate like parts in all the figures of the drawings.

The roof 1 is provided with the usual skylight opening 2 having a plain glass panel 3. The roof, in the present instance, is of the gable style, that is, slanting, and the upper and opposite sides of the opening are surrounded by walls at and 5, respectively. Each wall consists of a metal or other sash, 6, the

said sash when formed of metal being preferably U-shaped in cross section. In the sash there is slid aseries of ground glass panels '7, the whole constituting the Wall.

It will be seen that if at any time any one or more of the panels should become broken it may be replaced by another panel of similar kind. For instance, if one of the middle panels should become broken it may be removed and the other slid together after which a new panel may be placed in the end of the sash.

A skylight thus provided, it will be seen, is protected at certain times during the day from the direct rays of the sun which can only come through the ground glass before passing through the plain panel of the skylight and gaining access to the operating room, thus avoiding the necessity of employing numerous curtains and other necessary accessories.

Having described our invention, what We claim is- The combination with the transparent skylight of a photographic room, of a series of sashes arranged around or partialiy around the same, and provided with upper and lower parallel ways, and a series of independent ground-glass panels removably arranged in said ways for the purpose described, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
