coLoRnn LIGHTING SYSTEM.

Specification of Letters Patent. Patned Jan, 31, 192.2,

Application Afiled August 5, 1920.Y Serial No. 401,506.

To aZZtcLo/m, t may concern:

Be it known that I', IRA C. Woon, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Colored Lighting Systems, of which the following is a specification.

This invention is a colored lighting system adapted to produce,` novel lighting effects for theatrical and display purposes.

It is the object of the invention to provide a lighting system wherein different coloredl rays of light are blended to produce ornamental designs simulating flowers, drapery and the like. 1

The invention will be readily understood' from the following description of the accompanying drawings, in which- Figure 1 is a front elevation of a practical embodiment of the invention. Fig. 2 is a section through the same upon the line 2-2 of Fig. 1.

Fig. 3 is a front elevation showing a different form of the invention. l

Fig. 4 is a section on the line 4-4 of Fig. 3.

Fig. 5 is a somewhat diagrammatic showing of the testing means employed in blending the colors of the lighting system.

In the form of the invention illustrated in Figs. 1 and 2, a screen is' shown at 1 mounted upon suitable framing 2. A gutter 3 is formed in front of the screen at the base thereof and extending the width of the screen. This gutter may be formed by the angle strip 4 suitably secured to framing 2.

A plurality of usual incandescent lamps provided with uncolored lamp bulbs are arranged within gutter 3 along the same. The rays of light from lamps 5 are adapted to be projected upwardly-across screen 1 in .order to produce novel lighting effects upon said screen. For this-purpose a plurality of different colored light screens are arranged in gutter 3 in front of the lamps 5 in order to produce different colored rays of light projected across screen 1.

The light screens, preferably, consist of transparent uncolored bulbs 6 arranged to be removably supported in sockets 7 arranged along framing 2 within gutter 3. Different colored liquids 8 are contained within the bulbs 6 so that said bulbs will form different colored light screens.

In practice the sockets 7 are so arranged 'produce still different colors.

thatone of the bulbs 6 may be positionedin front of each of the lamps 5. These bulbs are shown at A, B, C, etc., as forming screens for producing the different colored rays of light A' B', C', etc. The points at which the different colored rays of light cross and blend are indicated at 9 at which points the blended rays. of light A2, B2, C2, etc., will Sockets 7 are, preferably,l also provided between the sockets in front of lamps 5, and in said sockets bulbs 6 forming light screens of still different colors are preferably, provided asv shown at A3, B3, C3, etc. `The l bulbs forming these light screens are, preferably, smaller than the bulbs forming-the u light screens infront of lamps', and' said light screens will project different colored rays of light A?, B4, C4, etc., between the rays 'of light A', B', C', etc., since the light projected through these latter light screens is projected from the lamps which are positioned at one side or the other of said light screens. The rays of light A?, B4, Ct, etc,

will be appreciably weaker than the rays 80 of lightA', B', C', etc. As a consequence the various rays of light will be intimately blended to produce a color effect of subdued tones simulating a silken tapestry or the like. Y

In the form of the invention illustrated in Figs. 3 and 4, a screen 1() is mounted upon a frame 1l and is provided with a central opening 12. A hollow shaft 13 is rotatably mounted in rearvof opening 12 and is provided with a plate 14 in rear of said opening.r rlhe shaft .13 may be rotated by any suitable means shown as comprising a pulley 15. A conduit 16 for electric wiring extendst-hrough the hollow shaft 13 in order that an electrical connection may be provided for a usual incandescent lamp 17, preferably, having an uncolored light bulb and mounted upon the plate 14 atthe axis thereof.

A plurality of sockets 18 are arranged'cir- 100 ment the light projected from lamp 17 '1045* through the different colored light screens will project rays of light A5, B5, C5, etc., of

different colors radially across vscreen 10.

llVhen plate 14 is rotated with shaft 13 the circumferential movement of the different 1710k U etc., thereof will cross.

colored rays of light Will cause blending of the same as seen by the eye in order to provide a novel lighting` effect which Will have the appearance of the petals of a flower.

T le construction as thus set forth affords simple means for producing pleasing lighting effects by the proper blending of different colored rays of light. rlhe beauty of the effects produced depend upon the proper blending` of the different colored rays of light irrespective of the particular mechanism which maybe employed for producing such blended effects.

ln practice the proper relative arrangement of the different colored light screens Will be found by experix'nents, and the necesn sary colors tov produce a desired effect may be found by arranging different colored light screens 22 and 23 With relation to one another as shown in Fig. 5, and projecting light through said screens so that the rays AG, BG,

n The stronger light will tend to blot out the weaker light and the exact blending* of the two lights may be observed in order to determine the positioning of said lights in the general color scheme to be produced.

Various changes may be made Without de-l parting: from the spirit of the invention as claimed. I

W hat is claimed is:

l. A colored light/inn system including a screen, a plurality of sources of light, different colored light screens in front of and in alinernent with said sources of light, different colored light screens in front of and between said sources of light, said light screens adapted to project rays of light in different colored paths across said screen, the paths of colors formed by said lights being such as to cause blending of said colors.

2. colored lighting` system including a screen, a plurality of sources of light, different colored light screens in front of in alinement With said sources of light, different colored light screens in front of and between said sources of light, said light screens being arranged adjacent said screen so that the rays of light will be project-ed in different colored paths across said screen, the paths of colors formed by said lights being such as to cause blending` of said colors.

In testimony whereof l have signed my name to this specification.
