- Feb. 23, 1932. F. ZABACH I ADJUSTABLE LIGHT HOLDERFOR MUSIC STANDS Filed March 5, 1930 A TTORNE Y.
Patented Feb. 23, 1932 FLORIAN ZABAGH, OF CHICAGO, ILLINOIS ADJUSTABLE LIGHT HOLDER FOR MIJ'SIC STANDS Application filed. March 5,
The invention relates to light holders for music stands. The object of the invention is to provide a light holder which may be re movably and adjustably attached to a music stand of the well known portable and foldable type.
Other objects of the invention not specifically mentioned may be easily understood and ascertained from the following description in connection with the drawings forming a part thereof. It is however to be noted that the invention is not to be limited or restricted to the exact construction or formation, v shown in the drawings and described in the i5 specification, but that the invention is only to be limited by the scope of the claim appended hereto.
In the drawings illustrating a preferred embodiment of the invention:
Fig. 1 is a front view of a music stand of the foldable type to which a light holder according to the present invention is attached.
Fig. 2 is a side view of the upper portion of Fig. 1. Fig. 3 is a front view of the light holder shown in a larger scale.
Fig. 4 is a side view of Fig. 3.
While the music stand is shown in detail in Fig. 1 it is not a part of the present invention and any music stand of suitable construction may be used to attach the light holder of the present invention. The light holder proper consists of an elongated reflector 5 adapted to receive an electric light 6, which in turn is connected through a cable 7 with a source of electricity. A stem 8 made from a metal tube is pivotally connected with the reflector and is preferably curved as indicated in Figs. 2 and 1. In order to hold the reflector 5 in the desired position in relation to the stem 8 a set screw 9 is provided.
A clamp 10 is made from one piece of metal by bending the same in an inverted U-shape and by bending the ends of the legs of the U at an angle of aproximately 135 to the upper portion as shown in Figs. 3 and 4. The two parallel parts of the legs may be strengthened by providing stifl'eners 11 between the two legs. Adjacent the lower end 1930. Serial No. 433,243.
one of the legs is provided with a tapped hole adapted to receive a clamp screw 12 by means of which the clamp may be removably fastened to any suitable and convenient part on the upper portion of the music stand preferably to the center part 13 of said stand which practically is present on well known portable music stands. Adjacent thecross piece of the U each of the legs is provided with a hole, the two holes corresponding witheach other so that the lower end of the stem 8 may be slidably inserted into said holes. The cross piece 141- of the U is provided with a tapped hole adapted to receive a set screw 15 by means of which the stem 8 may be secured in any suitable position in relation to the U- shaped clamp.
It is easy to see that a light holder according to the present invention may be quickly and readily attached to a music stand by simply inserting a flat portion of the upper part of the music stand between the leg portions of the clamp and by tightening the clamp screw 12. It is just as easy then to adjust the reflector 5 so that the light will be thrown directly onto the piece of music resting on the stand by first adjusting the distance between the reflector and the piece of music by sliding the stem 8 upwardly or downwardly and when the right distance is obtained by tightening the set screw 15. The direction in which the light is to be thrown may be regulated partly by rotating the stem 8 in the clamp before the set screw 15 is tightened and partly by adjusting the angular position of the reflector relative to the stem and then tightening the set screw 8.
Having described my invention and how the same is to be performed, I claim as new and desire to secure by Letters Patent:
In combination with a music stand, a reflector, a source of light arranged in said reflector, a curved stem pivotally attached to said reflector, a U-shaped member, the ends of the legs of this member adjacent the open 95 end thereof being bent at an angle to the portions of the legs adjacent the cross piece of said U-shaped member, each of said legs being provided with a hole adjacent the cross piece, said holes registering with each other and adapted to rotatably and slidably receive the free end of the stem, one of said legs being provided with a tapped hole adjacent the open end of said U a clamp screw fitting in said tapped hole, the cross piece being provided with a second tapped hole and a set screw fitting into said tapped hole and adapted to engage the stem after the same is arranged in the two corresponding holes. In witness whereof I aifix my signature.
