2 Claims.

upper and lower semi-spherical shells with clear and colored lenses positioned in spaced openings in the shells and with a motor, loud speaker and a light positioned on the interior of the shells.

The purpose of this invention is to provide a spotlight ball that produces a plurality of White and colored streams of light without the necessity of using a plurality of spotlights positioned at different points around a ball having reflecting surfaces thereon.

For display purposes and particularly in night clubs and the like spheres have been provided and small reflectors positioned at different angles on the surfaces and spotlights positioned at'different points and directed toward the sphere produce numerous streams of light which extend at different angles and in substantially all directions. With devices of this type it is necessary to provide electrical connections for each spotlight and it is also necessary to provide a motor for revolving the sphere. Furthermore obstructions temporarily placed between the spotlights and sphere interrupt the display of light; With this thought in mind this invention contemplates a sphere for producing a plurality of streams of light of white and different colors wherein the light originates in the sphere and the sphere is rotated by a motor incorporated therein.

The object of this invention is, therefore, to provide means for constructing a hollow ball or sphere wherein a motor, light and loud speaker may be mounted therein and wherein a plurality of lenses of different colors may be incorporated in the shell or surface.

Another object of the invention is to provide a device for projecting a plurality of streams of white and diflerent colored lights wherein the entire unit is self contained.

A further object of the invention is to provide a ball for producing small light streams of different colors which is of a simple and economical construction.

With these and other objects and. advantages in view the invention embodies a lower semispherical shell supported by a chain extended upwardly from the center of the lower surface, an upper semi-spherical shell positioned around the chain and resting upon the lower shell, a light, a loud speaker, a motor, and means supporting the light, loud speaker and motor in the spherical body formed by the shell.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a side elevational view of the improved spotlight sphere.

Figure 2 is a vertical section through the sphere.

Figure 3 is a sectional plan taken from a plane between the upper and lower sections of the sphere.

Figure 4 is a detail on an enlarged scale showing the flanges at the edges of the sections of the sphere.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved spotlight ball of this invention includes a ball or spherical shell having a lower section Ill, an upper section II, a bracket l2 supported by a chain I3, a motor l4 carried by the bracket, a light 15 and a loud speaker l6, both of which are mounted on the bracket, and a bar I! actuated by the motor and connected to the lower section ill of the shell by studs I8 and I9 which are threaded into lugs 20 and 21 on the lower surface of the bar I! whereby the shell is rotated by the motor.

The bracket 12 is provided with a vertically disposed section 22 on which the motor I4 is positioned and the bar I! is clamped to a sleeve 23 by an elongated nut 24 on which a threaded stud 25, which is threaded into the member 23 extends.

By removing the studs l8 and. [9 the lower section Ii] of the shell may be dropped or removed and by removing the nut 24 the motor may be removed for repair.

The light 15 is provided with a socket 26 that is secured to the bracket l2 by screws 21 and the loud speaker I6 is secured to the opposite end of the bracket by bolts 28. The bracket is provided with an eye 29 that is threaded into the upper surface thereof and the lower link of the chain I3 is secured in the eye 29.

The upper edge of the lower section II) is provide dwith a continuous flange 30 and a similar flange 3| extends around the lower edge of the upper section I I. The sections are provided with knobs 32 and 33 whereby the light openings or lenses in the two sections are aligned.

.The lower section I0 is provided with an opening 34 into which the nut 24 extends and the upper section I l is provided with a similar opening 35 through which a sleeve 36 having a flange 31 on the lower end extends as shown. The upper part of the chain I3 is secured in an eye 38 on the upper end of the sleeve 36 and the chain may be suspended from a book 39 in the ceiling or which may be threaded into a supporting element 40 as shown in Figure 1.

The openings in the lower section II) of the sphere, which are indicated by the numeral 45, may be open or may be provided with colored lenses 46, and similar openings 4'! in the upper section Il may also be open or. may be provided with colored lenses $8: The lenses ot'ibotl'r-secs tions are usually of different colors.

As illustrated in Figures 1 and 2 the chain may be connected to the eye 38 on the upper end of the sleeve 36 and also to a similar; eye 4.9 one,

the lower end, although it will be understood. that the sleeve 36 may be connected to the chain in any suitable manner.
