ooLoR PROJECTING'ATTACHMENT FOR ELECTRIC LIGHTS,

Raymond E. Jones and Dwight A. Elliott j g Richmond, Ind. I g

Application April 5,1933, Serial No. 664,588 2 Claims. (01. 240-31) it is to be understood that our invention not to v Our present invention relates to the refraction and dispersion of iridescent rays or gleams of electric light, I so projected and chromatically treated that the colorature of the emanating light will be completely transformed, in order to produce av delectable appearance to the projected light, and to the subject upon light are directed.

Specifically stated, our object is to provide a colortone device for attachment to an ordinary reflector, having an electric-light bulb therein and having means for illuminating the bulb in the usual manner, with our invention attached to said reflector whereby it appears as an integral part thereof, and having means whereby the'projected light passing therethrough will be directed fiaringly over a large surface at a distance therefrom," with the rays of light'formed in a desired color and broken up into innumeral rays, in order to give a new and pleasing'efiect thereto.

More specifically stated, our'object is to provide an attachmentfor artificial-light reflectors, especially adapted tobe employedfor advertising and decorative purposes'particularly in con-- nection with window displays, whereby'the goods displayed will be given a super-attractive appearance, and will attract attention thereto.

The means for carrying out the principles of our invention in a practical, efficient, economical, and: attractive manner is shown in the accompanying drawing, in whichFigure 1 is a perspective view of our construction, showing its connection'with the supporting elements employed therewith.

Figure'2 is a direct side elevation of our invention, showing the manner in which'it tached in operative condition.

Figure 3 is a' detail front elevation of our invention alone, as taken from the line 3-3 of Fig. 2.

Figure 4 isa side elevation of the attaching means alone, the same forming a minor portion of our invention.

Figure 5 is a detail plan view of one of the spring clamping members alone, as taken from the line 55 of Fig. 4. I Figure 6 is a detail view showing a fragment of the light percolator, as taken on an exaggerated scale. And Figure '7 is a front elevation of the bulb embracing means, as taken from the line '77 of Fig. 4.

Similar indices designate like parts throughout the several views.

In order to make clear the utilization of our invention, we will first describe one form of means with which our invention may be associated, but

which the rays of illuminating said bulb.

maybe at-' be limited to any particular type of reflector, or to the particular means for the supporter the positioning thereof. 1 I I 1 In this instance we have shown a supporting device, comprising the pedestal A, to which is adjustably attached the clamp B, which carries the electric-light socket'C. Also connected to -the clamp 13 is the outwardly extending and fla'ring reflector D, which should be formedcontorted in shape, for the purpose of diffusingor disseminat ing the rays of light reflected-by 'the inner'concave surface thereof and directed outwardly thereby at various angles in order to"obtain"a more pleasing effect, and a higher-[degree of a1"; tistry, with relation to duced. a g

Located within the -reflector D is an'electriclight bulb E, whose stem is detachably secured in the forward end of the socket C, inthe'usual manner. And'an electric circuit will be provided, through the wires F and G, for the purpose of The new and predominant features of our in-{ vention reside in the concave-convex conical light-percolator, which has as its'base," of'supf as a fine-mesh disc screen 1, whose outer periph-' eral portionis adapted to contact resiliently with the periphery of the reflectorD, with the; convex face ,thereof directed outwardly, that is forwardly with relation to the travel; of the light directed 1 by the reflector. Said wire screen 1', is covered with, and the interstices thereof are'closed; by a colored semi-transparent, or translucent, or other colorific material'2, such for instance, a flexible glass, or cello, which not'only'c'oversthe 15. the lighting'efiect proporting element, a; foraminated material, such strands of wire forming the screen, but perme ates and spans the-interstices '-'ofthe screen 1," as shown in Fig. 6. And, preferably, it is applied in'liquid condition, whichsoon solidifies to a semi-flexible condition. It is apparent that by reason of the semi-fluid material 2, when applied to the screen will, as it solidifies, naturally be-' come formed in the nature of arcuately-shaped cavities or double concave indentations on each, of the surfaces in the interstices formed by the screen which, when the invention is in use, will cause the light passing through the intersticesto be. broken up into innumeral minor rays of colored light and then transmitted therefrom and produce a most beautiful light effect, both when one is looking at the screen, or'in-the opposite direction where the light is directed upon'an object remote therefrom. It is contemplatedthat 4 each particular disc shall have its own particular sists of the following:' Formed through the eeri ter, or peak, of v thelight percolator is an aperf ture, which is surrounded by the wash-' ers 3 and 4, which are rigidly secured tothe-light percolating disc in any dwired .manner, but

preferablyby meansof an eyelet (not shown)..-

Numeral 6 denotes the knob member, which has a threaded socketfin the rear end of the stem I portion thereof, which is adapted to run on the reduced threaded portion of the coupling 5-and contantwith the shoulders thereof, wherebythe coupiingfiiand the light percolator disc are rigsecured together, .asshownin F'ig. 2.

{Spring wire, or its lequivalentis' employed "in the construction of the means for removably securing thedisc, into connection with the reflector I D, and this means comprises two arcuately shaped ' embracements 7 and 8, which correspond with the radial contour of the bulb E. The outwardly flaring-apart arms, 7 and 7", are formed by continuations from-the member'l; and likewise the outwardly flaring apart arms ,8 and 8" are formed by the continuations from the ends of the member 8.

The normal shape of said embracement members, together'withtheir arms,

are such that the curved rear portions. of said embracements, which contact with the -bulb E, have to be sprung apart topermit the bulb .E to

be embraced thereby. as shown in Fig. 2; and

Said disc is when released will retain the light-percolator in operative position. Said stem 11 extends into the socket of the coupling 5, or in some instances an i extension coupling 12 may be employed, which latter is longer than the coupling 5, and the stem 11 may be inserted in the socket of the knob 6, or other combinations may be employed in orlationto'the bulb. Said indu iiltibrs and ridges 10 are for the purpose of further refracting the :rays of light as it passes through the percolator disc, and also for supporting and stiffening the pemolator idisc.

From-the above it will be apparent that the constructionshovm herein will be capable'of obthe colorific and other objects herein set forth/and of carrying out the features'herein enumerated, in a practical and economical manner,v and with the attainment of a high degree of artistry. I I
