UNI TED S TATES T 12,493,829 Y l ILLUMINATING DEVICE Leslie R. Paul, Philadelphia, Ta.. Application February 12, 1946,'Seria1 N0. 647.103
-In prior Patent No. 12,374,640, April 24. 1945, I have' described and broadly claimed'a selective Kcolor control `for 'color illumination, Lv'vheriein 'a I'color cylinder -is selec'tive'ly positioned with respect to for revolved around 'a source of f light.
In 'my research son devices of this character extending over a considerable period, I have found that the V'n'n'junt'ing Iand arrangement of the duorescent :fixture and =the color cylinder are very important not only from the viewpoint of manufacture and assembly but also for the replacementof the vsourtie 'of light. 4Since the color cylinder tinay be revolved for ilong periods of'time., the mountings must be of =a durable nature, so that after installation they do not need 'Sto be disturbed 4in the replacement of' 'the source of light or the changing of thefcolorscheme ofthe c'olo'r cylinder if such change is desired.
The object, therefore, of this invention is to devise a novel device for color illumination adapted for a large variety of uses.
A further object of the invention is to devise a novel mounting for the source of light and for the color cylinder.
further object of the invention is to devise a novel illuminating device wherein the source of light, for example a fluorescent tube and its mounting, is contained within the color cylinder.
A further object of the invention is to devise a novel color cylinder.
With the foregoing and other objects in view as will hereinafter clearly appear, my invention comprehends a novel illuminating device.
It further comprehends novel means for mounting the source of light and the color cylinder. .4
Other novel features of construction and advantage will appear in the detailed description.
For the purpose of illustrating the invention, I have shown in the accompanying drawings a preferred embodiment thereof which I have found in practice to give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and the invention is not limited to the exact arrangement and organization of these instrumentalities as herein set forth.
Figure 1 is a sectional elevation of an illuminating device, embodying my invention.
Figure 2 is a section on line 2-2 of Figure 1.
Figure 3 is a section on line 3-3 of Figure 1.
Figure 4 is an end elevation of Figure 1.
Similar numerals of reference indicate correz sponding parts.
Referring to the drawings:
I designates the base of an illuminating device, embodying my invention. The contour andarrangement of the base may vary Widely in 2 Claims. (Cl. 240-10.1)
character in accordance vwith `the -place at which is to be instal-led; V y The base has a standard 2 to support -a motor 3 an'dits reduction gearing 4 so that :the motor shaft will slowly revolve, 'for example at a speed of one R. P. M. The motor shaft 5 passes through "the upwardly 4extending `flange of an angle 6, the bottom flange of which 'is fixed to the lbase -i-n any desired manner.
An ang-le 'I fixed 'to the base Aserves asv a mounting for a 'threaded Vsleeve 8 fixed v'to the upright flan-goof thea-ngle'lby nuts`8 in threaded engagement with the l'sleeve/at l'opposite sides iof the upright vflange.
The source of light has been shown as a fluorescent fixture ilo having its -conductor II passing '-'through the isleeve A8. The v`fixture |50 has an'angle plate I-2 'fixed ito it and fa-pertured to receive `the sleeve'i8 "to "-whic'h it 'is fixed by nuts I3. The fluorescent tube is shown at I4 and is mounted in the conventional manner for its easy replacement. The fixture I has an angle plate I which is apertured to receive a bearing I6 apertured to receive the motor shaft 5 which is fixed thereto by a set screw I'I.
A color cylinder I8 has flanged end members I9 and 20 connected by rods 2l, threaded at their ends to receive nuts 22. The end member I9 is fixed to the bearing I6 by nuts 23 in threaded engagement with the bearing, while the end member is apertured at 24 to ride on a smooth bearing portion of the sleeve 8.
The end member or cap I9 has a flanged ring 26 fixed to it and in a similar manner the end member or cap 20 has a flanged ring 21 fixed to it thereby forming spaces to receive the colored segments 28. One of the segments 29 is readily removable so that when removed the fiuorescent tube I4 may be inserted or replaced, and is retained in position by a nut 30 and screw 3| at each end, the screws having heads to overlie the segment.
It will now be clear that the light source is stationary being xed at one end to the angle standard 1 by the stationary bearing 8 and having its opposite end mounted on the revoluble bearing I6. The color cylinder is fixed at one end to the bearing I 6 and is revolved by the motor and at its opposite end it revolves on the bearing 8. The fluorescent tube is preferably mounted within the color cylinder so that it is off center with respect to the longitudinal axis of the color cylinder.
By removing the color segment 29, sufficient space is provided for the replacement of the fiuorescent tube.
For directional lighting, it is necessary to mask the light rays from the color segments which are not to be used.
The masking means is shown in Figures 1 and 4 but has been omitted from Figures 2 and 3. Masking plates 32 and 33 are shown in the form of segments having their end portions deflected at right angles and loosely mounted on the bearings 8 and I6 Yand .fixed in their adjusted position by nuts 34 and 35, respectively.v Y
The illuminating device is portable and can be secured to a wall or ceiling or other support to produce the desired color eiect. If supported in a horizonal position, the masking plates canl be fixed as shown in dotted lines inFigure 4 to cause the light rays to be directed both upwardly and downwardly, and the masking plates can be Y tion, a light source xture within the color cyladjusted so that the light rays are directed only upwardly or only downwardly. If the device is supported in a verticalposition, thermasking plates can be arranged as shown in full lines in Figurefl. Y Y Y Y Any desired arrangement or combination of color panels can be employed, and the width of the masking plates would Vary accordingly. As
shown, the colors are shown as arranged in sets of three colors.
The motor shaft has a bearing on the angle 6.
From a viewpoint of economy in manufacture and because aV slow speed motor is employed, the bearing surfacesof the Vbearings 8 and I6 have been shown smooth, but it is apparent that any desired type of anti-friction bearings can be employed.
It is to be understood that a remote motor control similarrtothat disclosed in my prior patent is employed to selectively position the color cylinder for a desired color or colors, or to effect the inder, nuts xing one end of said fixture on said sleeve, a second sleeve xed to the opposite end of the color cylinder and on which the other end of said fixture is loosely mounted, and a motor on `said base having its shaft mounted insaid other standard and fixed to said secondsleeve.
y 2, The construction defined in claim 1, wherein the standards are exible to permit their outer springing when assembling or removing the color cylinder. LESLIE R. PAUL.
