2 Claims.

This invention relates to electric wiring equipment, and more particularly to a hanger for electric fixtures.

The object of the invention is to provide an adjustable hanger for attaching ceiling fixtures to an electric outlet box.

Another object of the invention is to provide a hanger which can be adjusted lengthwise to support electric fixtures.

A further object of the invention is to provide an electric fixture hanger which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a front elevational view, in section, of the electric fixture hanger attached to a standard outlet box and a conduit;

Figure 2 is a front elevational view of the electric fixture hanger attached to an outlet box;

Figure 3 is a sectional view of the hanger taken on the line 3-3 of Figure 1;

Figure 4 is a sectional view taken onthe line 4-4 of Figure 1;

Figure 5 is a fragmentary front elevational view of the hanger for use with a fluorescent fixture and illustrating an electrical cable passing through a side opening in the hanger.

Referring to the drawings in detail, and particularly to Figures 1, 3 and 4 thereof, the numeral designates a standard outlet box provided with an aperture H in its top. A conduit l2 has a threaded connection or fitting l3 projecting down through the aperture II for a purpose to be hereinafter described.

The han er for su orting an electric fixture such as a ceiling lamp, comprises an anchoring bar l4 provided with a pair of opposed fluted feet and I6. Each of the feet l5 and H5 is provided with an elongated slot Figure 3, for receiving an end of a bolt l8, the bolt |8 extending from the top of the outlet box l0 through slot l1, and a castle nut I9 is threaded on the end of the bolt 8 to provide releasable support for the hanger.

Extending through the center of the anchoring bar l4 and secured thereto, as by welding, is a bushing 2|. The bushing 2| includes an upper internally-threaded socket 22 for threadedly receivin the threaded fittin l3. and the bushing UNITED STATES PATENT OFFICE UNIVERSAL ELECTRIC FIXTURE HANGER Clifton Evans Mosley, Jackson, Miss.

2 threaded cuff 24. The cufi 24 has a pair of opposed openings or apertures 25. Arranged in threaded engagement with the lower portion of,

the exteriorly-threaded cuff 24 is a first open-' ended screw section 26 which is threaded interiorly and exteriorly.

teriorly and is arranged in threaded engagement with the threaded interior of the first section 26. A third open-ended screw section 28 is threaded interiorly and exteriorly and is ar-"- ranged in threaded engagement with the thread-' bushing 2|, through the telescoping sections of 2| also includes an exteriorly-threaded lower the hanger, and through the top 29 of the fixture,

is cable 33 for electrically connecting the fixturebeing supported to a source of electric energy;

Referring to Figure 2 of the drawings, the electric fixture hanger is shown attached to a standard outlet box In that does not have a conduit and fitting projecting through the topthereof. Thus, there is an exteriorly-threaded stud 34 pro jecting through the aperture H in the top of the outlet box Ill, there being a suitable washer 35 interposed between the top of the box I0 and the flange 36 of the stud 34 and a lock nut 31 abuts the other side of the outlet box and is threaded on the stud 34. An adapter 38, which is threaded exteriorly and interiorly, serves to connect the lower portion of the stud 34 to the socket 22 of the bushing 2| which is part of the fixture hanger. In Figure 5, the hanger is shown attached to an outlet box in the same manner as in Figure 2, but the electric cable 33 extends through one of the side openings 25 in the cuff 24, and this adaptation is especially useful in installations of fluorescent fixtures.

In use of the arrangement illustrated in Figure 1, the hanger provides a convenient device for dependingly supporting an electrical fixture 29 from an outlet box l0. Thus, the anchoring bar I4 is releasably attached to the outlet box by means of the bolts H3, and further support is provided by the connection between the fitting l3 and bushing 2|. The screw sections 26, 21 and 28 are telescopically arranged so that the distance between the fixture 29 and outlet box |0 may be varied as desired and locked in place A second open-ended screw section 21 is threaded exteriorly and in by means of the lock sleeves. In Figure 2, the

hanger is shown attached to an outlet box H! which does not have a conduit l2 and fitting I3. Thus, a stud 34 and adapter 38 connect the outlet box III to the top of the hanger to supplement the bolts 18 in supporting the hanger and fixture carried therebetween. In Figure 5, the hanger is shown as used for supporting a fluorescent-type fixture, the cable 33 passing through one of the apertures 25 in the cuff 24 and extending to a suitable fixture.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:
