COLOBED-LIG-HTING i Dnvron Application filed April 23, 1921. Serial No. 463381.

T 0- aZZ whom it may conccrn:

Be it known that l, TBA C. VVooo, a citizen of the United States, residing at South Pasadena in the county of Los Angeles and State of California, have invented new and useful Improvements in Colored-Lighting Devices, of which the following is a specification.

This invention is a display device adapted to produce noveland pleasing color effects' and the invention consists essentially of a dished screen member across which rays o' variously colored lights are projected 'so as to produce a pleasing rotating color effect. A casing is mounted at the center of the screen and contains a rotatable source of illumination which is preterably provided with variously colored circumterentially related portions. A plurality of transparences are provided at the periphery of the casing around the rotatable source of illumnation, and closure plates are arranged beyond some of the transparencies, so that by opening and closing the same, certain of the rays of light may be cut oti n order to modify and vary the lighting efiect produced by the mechanism. v

By means of a structure as thus set forth, a remarltable brilliant and beautiful lighting effect may be produced upon the dished screen of `he apparatus, and the mechanism will be 'found of practical advantage as an advertising medium or the like.

The invention will be ,readily understeod from the following description of the accompanying drawings, in which:

Figure 1 is a front elevation of a devce constructed in accordance with the invention, and showing the casing and the parts contained therein in vertical section.

Fig. 2 is a side elevation of the mechanism partly broken away.

Fig. 3 is a detail transverse section on.

the line 3-3 of Fig. l.

The dished screen of the mechansm is shown atl mounted upon a suitable sup-` beyond casing 4: and is provided With con The tube 6 also carries a contact ring 15 i w 1): a n

which .is en 'aged by a contact 16 also con nected to the positive wire 13. The ring 15 carries a spring contact 17 co operating with a plate 18 provided with a plurality of circumt'erentially spaced Contacts 19 so that as the tube 6 and lamp 9 rotate, a circuit is successively closed through spring contact 17 and the respective contacts 19 tor a purpose to be hereinafter described.

` The .tube 6 may be rotated by a gear 21 fixed *thereon and received within casing a said gear meshing with a pinion 22 upon the shaft of a suitable electric motor which is adapted to be energized by thesourcerei electrical energy.

The casing 3 receiving the with relation to one another.

As a consequence it will be noted that the rotatlng lamp 9 wllcause a rotating varilamp 9 is pro I vided with a suitable closure plate 25 which ously colored source of illumination, which co-operating with the variously colored transparencies around the periphery of the casing and adapted to form a magni'fying means will cause projection of variously colored rays ot' light across'the dished screen' ot' the apparatus, and these rays oflight will be constantly changing and blending so as to form an extremely pleasing etfect.

v In order to still further vary the effect produced by the rays of light passing across i the dished screen, the openings29 intheperihpery of the casing are preferably provided with closure plates 33 axially slidable in guideways 34 and arranged to he normally closed and automatically successivelyopened by actuating means controlled by the electrical circuits successively made "through the engagement ol" contact arm 17 Springs 37 arranged upon the Operating" to close' for, the

rods normally shift the latter so as plates`33 and When the solenoids Operating rods are energized,` the lil'osre plates are shitted to open position against the tension' of their springs. The respective solenoids are in the resz ectiv circuits closed by contact arm 17 and contacts 19 in order that the solenoids Will be successively ener`- gized for successively opening the closure plates While contact arm 17 moves over the respective contacts 19.

The construc'zion as thus set forth, provides a pleasing advertising novelty or other display device which is arranged to form a constant-ly changing color scheme upon the dished screen of the apparatus, the color scheme providing beautil ul blending of the various colors so as to form only Varying shades.

various changes may be made Without departing from the spirit ot 'the invention claimed; e i i What is claimed is:

1. A display' device comprising a rotatable source of illumination having various colored portions circumferentially disposed With relation to one another, and Variously colored transparent stationary members arranged in circumferential relation around said rotatable source of illumination.

2. A display device comprisinga rotatable source of illumination having various colored portions circumferentially. disposed With relation to one another, and Variously colored transparent members arranged in circumferential relation around said rotatable source ofillumination, and closure plates co-operating With said transparencies to cut oti' or display light through the same. i

i 3. A display device comprising a dished screen,'a casing at the center thereof having Variously colored peripheral transparencies, and a rotatable source of illunination Witlr in said'casing having Variously colored portions.

4. A display device comprising a rotatable source of illumination having' variously colored portons crcumferentially disposed With relation to one another, and Variously colored` transparent members arranged in around said rota nn.. ciosure plates trangoerencies and circumferential table source ot' w cooperatin: W m electro-respensive mean. opening' and then closing said` plates."

5. A display device comprising a dished screen, a at the center 'thereof having Variously colored peripheral transparencies, closure plates ro; said tranparencies means for opening and closinr said plates and a rotatable source of illuinination within said casin having variously' colored portionsi 6. ri display der *ice comprising a rota'table source of illuriination having variously colored portions circuin'ferentially disposed ing means for successively opening; and then closing said plates; said means being con-` trolled by the rotation of said source of illu mination.
