UNIVERSAL SUPPORT FOR LIGHT FIXTURES Filed April 6, 1958 Patented May Z8, y1940 UNITED STATES PATENT OFFICE .2,202,680A UNIVERSAL `SUPPORT Fon LIGHT FIXTURES Abe s. zagel, chicago, III. Application April 6, 193s, serial No. 200,505 1 claim. (Cl. 24o-Lis) This invention relates to a universal support for light fixtures, and has, for one oi its principal objects, the provision of a support for light xtures or electric lamps which is so constructed that it can be readily applied to practically any ceiling fitting now in use without the necessity` of any special fittings or other arrangements or devices which have heretofore been considered necessary in constructions oi this type.

One of the important objects of the invention is to provide a light fIxture adapted for supportmanner and one which can be readily assembled in position without the use of lspecial tools or other fittings.

Another important object of the invention is to provide, in an electric light fixture or the like, means for passing a pull cord or chain from. an operating switch in the interior of the struc- QG ture down through the fitting or support for the transparent globe whereby the switch may be operated in a convenient manner and whereby, at the same time, unsightly fIttings and other appurtenances will be eliminated. 5, Another and still further important object of the invention is the provision of a universal fitting or support for electric light housings or structures which is adapted for immediate use in practically any situation and which will eliminate the necessity of drilling or tapping holes in either the original support or the tting itself and which, furthermore, can be installed without the use of additional tools or special equipment.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawing and following specifIcation.

vThe invention, in a preferred form, is shown 40 in the drawing and hereinafter more fully described.

In the drawing:

Figure l is a side elevation, parts being broken away, of the improved universal support for light 45 xtures of this invention.

Figure 2 is a bottom plan view of the structure of Figure 1, the light globes' and transparent cover being removed.

Figure 3 is a top plan view of the structure of 50 Figure l, showing certain of the universal attachment ttings.

Figure 4 is a detail sectional view of the structure of the preceding figures, showing the same as applied to one type of support which is in com- As shown in the drawing:

The reference numeral Ill indicates generally the main supporting plate of the yimproved universal globe tting of this invention, the same havinga surrounding rim or thelike i2 which 5 may be either separate from or integral with the plate l and mounted on the plate are two or more electric light sockets I4 of the usual construction. Wires l6 lead into the socket I4, and these wires pass upwardly through openings I8 i0 lin the plate il! running to suitable connections in the ceiling. i

It has been found in practice that the fittings in the ceiling such as the fittings shown in 2'0 in Figure 4. are of varied and various types, shapes, l dimensions and constructions so that, in many instances, it becomes necessary to rearrange or even substitute a lamp support in order to accommodate a particular type of ceiling fitting which has been installed in either a new or an old dwelling or other building.

One particular type of attachment is illustrated at 22 in Figure 1, this comprising a cylinder entirely open at its top end and closed at its lower end except for a smallcentral hole to allow the 25 screw 24 to pass through. The cylinder 22 is interiorly screw-threaded and is adapted to fit the correspondingly screw-threaded end of gas pipe or the like which is sometimes placed in ceilings for this particular purpose. This ele- 3U ment 22 is held in place by means of a screw 24 as best shown in Figure 3 so that it` can be removed if desired. p

In Figure 4, the device of Figure 1 is shown as applied to a different type of` ceiling tting 20 35 which ordinarily comprises a box-like structure having holes drilled and tapped therein for the reception of machine screws or the like 26. It often happens that these holes are in different positions depending upon a particular type of housing or box 20, and obviously unless the structure Illl2 is drilled to correspond to the locations of the holes in the element 20, its ready installation will be accordingly delayed or rendered difficult, is not actually necessitating the substitution of a different type of support or ltting.

To this end, I have provided slotted openings 30 in the plate I0 as best shown in Figures 2 and 3, these openings having venlarged ends as illustrated at 32, these enlarged ends being preierably circular and of a size to accommodate the head of an ordinary machine screw 26. The slotted openings 30 are of suicient length so'that the distance between screws 26 can be readily varied, thereby enabling the device of this invention to accommodate itself or to be readily applied to a connection box 2|3`of practically any type, size or design. An additional opening 34 is also prosized supports.

Also mounted of the screw 24 or by spot welding or in any other adapted to be supported.

A pull chain 42 extends downwardly from the switch 40 and through a hollow exteriorly screw-threaded tube positioned in a correspondingly screw-threaded opening in the lower end of the element 36.

Also adapted to be mounted on the screwthreaded tube 4 is an interiorly screw-threaded element 46 having associated therewith a. flat washer 48 which last-named fittings, in turn, act to support a transparent globe or the like 69 in position with regard to the supporting plate Ill-l2.

ment, thereby providing a neat and attractive unit.

It will be seen that herein is provided a unifittin'g 44 which quire any other equipment except the ordinary supporting screws and a screw-driver for applying the same. Additionally, the novel form of switch mounting ABE S. ZAGEL.
