This invention relates to illuminating apparatus, and has for one of its objects to provide a novel and simple apparatusof this character which shall be adapted toproduce multi-colored light effects ofsuch pleasing character as to adapt it to be used for the purpose of attracting attention to the display windows of stores and for the purpose of illuminating ball rooms and'the like.

To attain the foregoing and other objects, the nature of which will appear as the description proceeds, theinvention comprehends the provision of an illuminating apparatus which will embody a multi-mirrored reflector, means by which the reflector may besecured in a vertical position to a wall or the like, or in a horizontal position to a ceiling or the like, a shaft axially related to and rotatably supported by the reflector, an incandescent electric lamp carried byt-he shaft for rotation therewith, a globe carried by the shaft in surrounding relation to the lamp for rotation therewith and having differently colored lenses and openings between the lenses, means for rotating the shaft, and means for supplying the lamp with current.

The invention is hereinafter more fully described and claimed. and illustrated in th accompanying drawings, wherein Figure 1 is a sectional view taken on a plane extending vertically and centrally through an illuminating apparatus constructed in accordance with my invention;

trating the means for rotating the shaft and the lamp and globe carried thereby, and also illustrating the means through the medium of which the lamp is supplied with current;

Figure 1 is a top plan view on an enlarged scale of a fragmentary portion of the lamp globe illustrating the manner inwhich the colored lenses are maintained in globe formation, and

Figure 5 1s a detalled sectional view taken on the plane indicated by the line 55 of Figure The illuminating apparatus comprises brackets 1 and 2, which are arranged in spaced parallel relation and which are of substantially inverted U-form in side elevation. The rear side bars 3 and the front side bars 4 of the brackets 1 and 2, are provided at their lower ends with angular extensions 5 and 6, respectively, which are apertu'red for the reception of attaching screws 7 or the like; A plate 8 supported by the brackets 1 and 2, has its ends positioned upon and secured, as at 9, to the top bars 10 of the brackets.

Areflector 11 consisting of a sheet metal shell 12, and an inner series of mirrors 13 and an outer series of mirrors 14 secured within the shell, is secured through the medium of the shell to the front bracket bars 4-. These bracket bars are curved longitudinally forthe greater portion of their length to receive the lower portion of the reflector shell12 which is secured thereto, as at 15. The series of mirrors 13 are angularly related to the series of mirrors 1 1, and the mirrors of the respective series are angularly related. 1

The reflector 11 is positioned at the front side of and extends above the support consisting of the brackets land 2 and the plate 8, and it is provided at its axial center,-which is located above the support, with a bearing sleeve 15 secured to and extending rearwardly from the reflector shell 12. A hollow shaft 16. is journaled in the bearing sleeve 15, and extends forwardly and rearwardly beyond the sleeve. Theshaft 16 is held against endwise movement with relation to the bearing sleeve 15 by a collar 17 and a worm gear 18. The collar 17 is secured to the shaft 16 and bears against a flange 19 which is carried by the front end of the bearing sleeve and through the medium of which the bearing sleeve is fixed to the reflector shell 12. The gear 18 is fixed to the rear end of the shaft16 and bears against the corresponding end of the bearing sleeve 15.

A socket 20 of insulating material is screw threadedly engaged, as at 21, with the front end of the shaft 16, and is provided with a metal bushing 22 and a central contact 23. Contact rings 24: and 25 are mounted upon the rear side of the gear 18 in a concentric relation thereto and to each other. The contact rings 24 and 25 are insulated from each other and from the gear 18 by a ring of insulation 26 which is suitably secured to the gear and to which the contact rings are suitably secured. A conductor 27 is connected to the contact ring 24 and to the socket bushing 22, and a conductor 28 is connected to the contact ring 25 and to the socket contact 23. The socket bushing 22 is screw threaded for the reception of the base 29 of an incandescent electric lamp 30.

The lamp 30 which extends forwardly from the shaft 16, and is located forwardly beyond the reflector 11, is surroun'dedby a globe 31 consisting of colored lenses 32. Some of the lenses 32 are of ellipical contour, others of angular contour and others of circular contour. The lenses 32 are arranged in annular series, each series may consist of lenses of the same ordifferent'contours, the lenses of eachseries are of different colors and the lenses of the respective series-are so. relatively arranged that no' two lenses of the same color are located directly opposite each other. The lenses 32 are each mounted in a light metal frame 33. The lens carrying frames 33 are soldered or welded together, as at 34, to secure thelenses in globe formation.

.The lens carrying frames 33 are so secured together as to provide openings 35 between the lenses.

The foremost series of lenses 32 has its front side closed by a colored lens 36 which is also mounted in a frame soldered or weld- .ed to the frames of the foremost series of lenses. A pin 37 secured to the lens 36 in alinement with the longitudinal axis of the globe 31, extends forwardly from the globe, and is provided at its front end with a transparent disk 38 which maybe a trade name, an advertising slogan, a picture, or the like. The globe 31 is provide. at its rear end with a sleeve 39 which surrounds and is screw threadedly engaged with the socket 20, the sleeve securing the globe to the socket for rotation with the lamp 30, and. the pin 37 securing the disk 38 to the globe for rotation therewith.

An electric motor 40 is provided to effect the rotation of the shaft 16 and consequent- -ly the rotation of the lamp 30, globe 31and disk 38. A worm pinion 41 fixed to the armature shaft 42 of the motor40, meshes'with the worm gear 28 to effect a driving connection between the motor and shaft 16. The motor 40 is mounted upon and suitably secured to the plate 8 at oneside of the gear 28, and its armature shaft 42 and pinion 41 are located at the lower side of the gear. A

J block 43 of insulating material is positioned upon and suitably secured to theplate 8 directlybelow the pinion 41, and brushes 44 in the form of leaf springs are secured to and extend upwardly from the block 43. A switch 45, which is mounted upon and suitably secured to the plate 8, and which is adapted to be secured by a"eord 46 to an electric outlet socket or the like, is connected by conductors 47 to the brushes 44, and the brushes 44 contact with the conductor rings 24 and 25 to the end that the lamp 30 may be supplied with current.

In practice, the apparatus may be mounted in 'a display window of a store with its reflector 11 in a vertical position and its globe 31 in a horizontal position, or it may be -mounted in a ball room or the like, with its ter borne by the disk. As thelenses 32 are of different colors, and as they, together with the disk 38, are rotated-with relation tothe ,reflectorll, there will be produced a multicolored lighteffect of very pleasing character. It will be understood that the rotation of the lamp 30, the globe 31, and the disk 38 is effected through the medium of the motor 40, and that the lamp is supplied with current through the medium of the cord46, conductors4'Z, brushes 44, rings 24 and 25, and

conductors 27 and 28.
