ELECTRIC-LIGHT FIXTURE FOR MUSIC-STANDS. I

Application filed January 14, 1918. Serial No. 211,718.

To all whom it may concern:

Be it known that I, ISAAC J. FLA-es, a citizen of the United States, residing at Cambridge, county of Middlesex, State of Massachusetts, have invented an Improvement in Electric-Light Fixtures for Music- Stands, of which the following description, in connection with the accompanying draw- 7 ing, is a specification, like characters on the 10 drawing representing like parts.

This invention relates to an electric light fixture adapted for use on music stands, desks and such like, and the object of the invention is to provide a novel fixture by means of which substantially all the light rays from the electric light bulb will be directed onto the music supported on the music rack or on the reading matter on the desk, pulpit or other support, so that the proper illumination can be provided with a relatively small current consumption.

Another object of the invention is to provide a novel device which will illuminate only the music on the music stand or the reading matter on the desk or pulpit and will not light up the surrounding area to any extent. For this reason the device is especially useful in lighting the music stands of orchestras in theaters where it is desirable to so control the light which the orchestra uses that the audience will not see the light to any extent.

Another'object of the invention is to provide a novel electric light fixture having the above characteristics in which the electric light bulb is suspended vertically, the advantage of which is that the bulb is less likely to become broken than when it is sustained in a horizontal position.

In order to give an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims.

Figure 1 is a perspective view of a music stand having my improved fixture applied thereto;

Fig. 2 is anenlarged vertical sectional view;

Fig. 3 is a front view.

I have shown at 1 a music stand of any ordinary construction to which my improved fixture is secured. I would state, however, that the device can be used equally as well on a desk, pulpit or any other simi- Specification of Letters Patent. I Patentd Get. 7, 1919.

lar stand or support. The device comprises a hood or reflector device 2- which is especially shaped to produce'the desired ad- Q vantageous results above enumerated. It is provided with the top portion 3 which carries an electric light socket 4: from which a bulb'5 depends, two sides 6 which incline downwardly and outwardly from the top 8 and a front and back 7 and 8. The top, sides, front and'back are so connected as to leave an open bottom 9 through which the 1 light-is projected.

In order to provide a device which will illumine the music on the music stand 1 without materially illuminating any of the space around the stand, I propose to 'make the back 8 concavo-convex 1n shape in a vertical direction only so that the inside will present a concave surface, the concavity extending from topto bottom. The lines of the back extendingfrom one side to the other are straight.

The front 7 is made wlth the conca-voconvex upper portion 10 and with the plane lower portion 11. The portion 10 is concaved in a vertical direction only, the horizontal lines thereof being straight. The lower plane portion 11 of the front is inclined slightly so that it stands substantially parallel to the lower portion of the back. The bulb 5 is received in the space between the back and the curved upper portion 10 of the front.

The inside of the hood or reflector 2 is made so that it will reflect the light. This may be done by painting it white or by providing it with some coating of reflecting material. It will be noted that the lamp 5 is situated in the upper part of the hood or reflector and that the lower edge thereof extends a considerable distance below the lamp. The relation between the front, back and sides is such that the opening 9 is a relatively long but narrow opening, and the relative shape and position of the front, back and sides and the position of the lamp relative thereto are such that a maximum amount of light will be either directed or reflected through the opening 9 in the bottom of the hood onto the music stand, and since the light rays which illuminate the music stand come not only directly from the bulb, but also from the front and back of the hood or reflector, the illumination of the light rays through the open bottom 9. I will preferably make the inside face of the hood of a character which will diffuse to some extent the light-reflected therefrom so that the reflected light will be soft in tone. I will also preferably use a bulb 5 which has the lower part thereof frosted so that the light projected downwardly from the bulb will beso-ft in character. Bythis means a very even soft light is produced. I 7

Further, since substantially all thelight rays from the bulb are used in illuminating the stand it is possible to use an electric lamp. of relatively small candle power and yet secure sufficient illumination. This results in a decided saving in current consumption. Furthermore, the bulb 5 hangs vertically and this isan advantage because the filament in a vertically-sustained bulib will "last longer and is much less liable .to become broken than that'in a bulb which is sustained .in a horizontal position. 7

The reflector may be secured to themusic stand in any suitable way I have herein shown :it as being provided with a stem or arm 12 which is adapted to be fastened to the backside of the music stand by any suit able means, such as the screw 13.,
