Application February 15, 1954, Serial No. 410,088 6 Claims. (Cl. 240-138) The present invention relates to an improved lighting device and it relates more particularly to an improved device of the spotlight type for use in connection withk the lighting of window displays, display counters, stage presentations, and in many other similar applications.

In the proper and effective lighting of window displays, counter displays, and other displays requiring an attractive and appealing presentation it is necessary to employ numerous spotlights and lighting fixtures whose arrangements, patterns, intensities and colors depend largely on the particular display. These displays, being frequently changed, necessarily require the frequent changing of the lighting fixture arrangements as well as of their individual characteristics. The lighting fixtures and spotlights conventionally employed are bulky and expensive devices of little versitility or flexibility and" diicult to handle.

Thus the proper and effective lighting of displays with the lighting fixtures and spotlights heretofore available is awkward, highly time consuming and expensive. Furthermore, since the fixtures themselves are expensive and heavy and the support structures are correspondingly heavy and complicated the initial installations are likewise costly.

It is thus a principal object of the present invention to provide an improved lighting device.

Another object of the present invention is to provide an improved electric spotlight.

A further object of the present invention is to provide an improved mount for the conventional spotlight type electric bulb which can support the bulb in any desired direction and position in a variety of manners and which is provided with means for removably holding one or more lenses, filters or similar optical elements confronting the face of the bulb.

A further object of the present invention is to provide an improved simple mount for removably supporting a spotlight type of electric bulb for universal adjustment and having means for holding one or more lenses, light filters, and other optical elements in front of the facepof the electric bulb.

A further object of the present invention is to provide an improved mount for spotlight bulbs and co-acting optical elements said device being characterized by its ruggedness and high versatility and flexibility as well as its simplicity and inexpensiveness A further object of the present invention is to provide a simple improved mount for spotlight bulbs and co-acting optical elements which permits support of the assembly in various attitudes and positions and by variousvmeans.

The above and further objects of the present invention will become apparent from a reading of the following description taken in conjunction with the accompanying drawing wherein:

Figure l is a front embodiment of the on a flat base;

Figure 2 is a side elevational view, partially in section,

perspective view of a preferred present invention shown mounted 2,822,462 Patented F eb. 4, 1958 illustrating the improved device employed with a conway of a pair of prongs horizontal and abutting the lower face of ventional large size projection bulb;

Figure 3 is a side elevational view, partially in section, illustrating the improved device employed with a conventional small size projection bulb;

Figure 4 is a sectional view taken along the line 4-4 of Figure 2; and Y Figure 5 is a side elevational view, partially in section, of another embodiment of the present invention.

Reference is now made to the drawings and more particularly to Figures 1 through 4 thereof which illustrate a preferred embodiment of the present invention, and wherein the-numeral 10 generally designates the improved device, and the numerals 12 and 14 indicate conventional large size and small size projection bulbs employed with the present device. The bulbs 12 and 14 are of conventional construction including an evacuated envelope having a front or lens portion 16 and an internally coated refiector portion 18 circumferentially joined by a heavy outwardly projecting reinforcing rib 20. Electrical energization ofy the bulb filament is effected by 22 connected to the filament and projecting laterally from the base 24 of the bulb. The prongs 22 are of such configuration and spacing as to accommodate theconventional electric socket employed with thesel bulbs. The bulbs 12 and 14, for present purposes, differ principally in the diameter of their rib portions 20 and in their overall length.

The bulb mount and filter holder 10 includes a shell 26 of roughly tubular configuration having a rear cylindrical wall 28 terminating in a beaded edge and an inwardly curved forward Wall 30 terminating in an inwardly directed fiange 32. A plurality, preferably three, of transversely extending circumferentially regularly spaced horizontal slits 34 are formed in the cylindrical wall 28 the lower borders of the slits 34 being inwardly depressed to permit the vertical passage of a strip therethrough as illustrated.

A clip member generally indicated by reference numeral 36 registers with each of the slits 34 and is formedY of an elongated band or strip of resilient material. The clip 36 includes a main vertical leg 38 abutting the inner face of the shell 26 and passing vertically through a corresponding slit 34. Depending from the leg 38 is an arm 48 normally substantially tangent to the curved wall 30 and joining an inwardly directed leg 42 normally the ange 32 and extending to a point short of the inner edge of the ange 32 where it joins a downwardly and slightly inwardly directed leg 44 which in turn terminates in an outwardly downwardly directed lug 46. Each of the legs 38 is inwardly and thence outwardly curved approaching its upper end and is there joined by an inwardly and downwardly directed leg 48 forming an acute angle with the leg 38. The leg 48 is followed successively by a rearwardly downwardly directed leg 50 extending by way of a curved joint into a downwardly and inwardly directed leg 52 which terminates in a downwardly and outwardly directed lug 54. It should be noted that the upper end of the clip 36 including the legs 48, 5f) and 52 and the lug 54 constitute the lamp engaging portion of the4 clip136, whereas the lower portion of the clip 36 including the legs 40, 42 and 44 and lug 46 constitute the optical element-engaging portion of the interior directly below the clip lug 54 with which it co-v engaging and supporting. spotf acts to provide means for v lights of .smaller dimensions, as in Figure 3.-

Each oftheclips 36 is secured in the position shown by means of` A curved supporting arm or bracket 60 is pivoted at its lower end to the shell wall 28 by means of an outwardly projecting screw 62 xed to the wall 28 and passing through an. obeuinsiu the .lower eud of tbe larm 69'.
