srncrrrca'rion'formm part of Letters Patent No. 720,935, dated Februar 17,1903.

Application filed September 22,

To all whom it may concern)! Beit'known that I, ANTO1 IT.KLIEGL, a subof the Emperor of Germany, the borough of Manhattan, in the city,

tion with two or more series of incandescent or similar lamps of difierent colors, the whole constituting a device known as border 7 or foot lights for use in the flies of a theatrical stage. These devicesare used to produce I of different colors, and as heretofore constructed they comprise an ordinary reflectorbefore which the lamps with globes of difierent colors are arranged in a row. It has been found,however, in the'use of'such devicesthat when the lamps of one color are' in circuit the light-rays, including a 'portion of those emanating directly as well as those reflected, are frequently strongly tinted by the colors of the globes of the neighboring inactive lamps, so that the desired effects are this, .I have not fully secured. To remedy devised a novel form of reflector which,'gehe'rally speaking, consists of the'ordinary inclosing cnrvedhood or shield,-before' which the lamps are mounted in a row, and plates with reflecting-surfaces secured within "the hood intermediate to the by the lamps and forming shields which prevent the rays from one lamp from passing other.- r

I am aware, of course, that a series of in-, dependent reflectors series of lamps as at; problem of the mere interference of the lights of diflerent colors; but such an arrangement would be impracticable, because among other reasons the row of lamps must generallybe very long and at the same weight and maximum strength, so as to be not be possible within limits of practical cost residing in county, and State of New York, have invented certain position occupied might be used with each obvious solution of the time of minimum andof somewhat 1e02 SerialND. 124.299. iliomodel.)

if a large were mounted on a sufliciently strong sppport of the length usually required.

In carrying out my invention I construct the device as I haveillustrated-itin the ac-- companying drawings, in which 7 Figure 1 is a front elevation with a portion of the base removed. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1, and Fig. 3 a transverse section on line 3'3 of Fig. l.

The. base Bot the device,in whichare mount-- ed in a row a series of lamp-sockets A, is formed, preferably, of sheet metal'bent-into approximately rectangular form and'streng'thened by a wire 0, around which the front edge of the metal is bent, as rear edge of the sheet metal is extended beyond the level of'the base and is formed into number of independent reflectors indicated; The v a hood D, its ends and edge to secure greater rigidity being wrapped around wires E.

The rectangular 'trough or base is formed with a raised portion or corrugation, upon which the lamp-sockets are mounted. This corrugation imparts greater rigidity to thedevice. V

H isa sheet-metal cover containing per forations, through which the necks of -the globes G may be inserted into the sockets beneath. The front edgefof this cover is formed with a curved lipI, which fits over the wire edge of the base B, while-its rear edge is bent upward to rest against the lower edgeof the hood D. To this latter the cover is secured by bolts J "or similar devices, which may be removed to permit the withdrawal of the cover when it is desired to obtain access to the interior of the base to make repairs. 1

To the interior surface of the hood D impositions intermediate to the lamp-sockets hrs secured metal plates F, preferably formed. by bending .fiat plates to approximately a \l-seetion and cutting their-edges to conform to the shape of the hood. These plates extend down to nearly the level of the lainpsocket,-as indicated in Figs. 1 and 3, and outward sufliciently to prevent the-rays from one lamp passing throughthe globe of another.

The bent plates may be soldered or riveted in position. They may he of any proper aterial and may be madein various ways difierent shapes, accordi;

to circumstances. More than one piece material may be used for each.

globes G are of blue glass and the: others of red the light effect on the scenery of one series wiii be distinctly blue, while that of the other will be red, and that there will be no intermingling of the two tints.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, ,is-

In border or foot lights, a base composed of a trough of bent sheet metal adapted to supvzoess I It will be un- 1- port a series of lamp-sockets inside the same,

.derstood that if a certain number ofthe lampa cover therefor having apertures re istering' with said sockets, lamps in said sgcketa-a hood on ohe side of said trough extending over the lamps and constituting a reflector therefor, and curved reflector-plates secured in said hood between the lamps, substantially as shown and described.
