LIGHTING FIXTURE.

I Application ledJuly 7,

Uur invention relates to lighting fixtures particularly of the character wherein the globe or shade is supported by fingers contacting with its inner surface under the rim with a shell bearingupon the outer surface of the globe or shade to prevent slipping. One obJect of the invention is to simplify construction and lessen the cost of manufacure; another object is to provide a hanger equally well adapted for use in a suspended fixture or one connected directly with a ceiling; another object is to provide meansfor focusing the lamp; another object is to facilitate the adjustment of the canopy in ceiling fixtures to give free access to the outlet box and wires at such point without the necessity of removing the canopy or disturbing the fixture. Other objects and advantages of oui` invention will be apparent by the` description following.

' In the accompanying drawings: Y

Figure 1 is a central vertical elevation of a hanging fixture embodying our invention.

Fig. 2 is a front elevation of the yoke detached showing a modification in the manner of supporting the lamp receptacle.

Fig. 3 is a side view of the same.

Fig. 4 illustrates a modified manner of connecting the yoke with the shell, parts being broken awa Fig. 5'is a sidye view of the stud upon the toprof the yoke, which is shown broken away.

ig. 6 is a top view of the same, and v Fig. 7 is a central vertical elevation of a ceiling fixture embodying our invention.

Referring to the drawing, we employ a yoke made preferably of a single fiat strip of metal bent to the shape shown, that is, having a horizontal top 10, vertical sides 11, curved outwardly as at 12 a predetermined distance below the top, then vertically or nearly so as at 13, then horizontally as at 14, which'horizontal portions are inserted wlthin the mouth of the globe or shade 15 forming interior seats for the rim thereof. The ends of the portions 14 are preferably rounded and bent slightly downwardly to conform to the shape-of the glasware.

The arms 11 and 12 of the yoke have a certain degree of resiliency.

A stud 16 is secured to the yoke at the center of its top l0 in any suitable manner. `We have shown the stud provided with an annular shoulder 17a't its lower part, a re- 1927. Serial No. 203,884.

duced lower end passing through a central opening 1n the top of the yoke and upset against the under surface of that member of the yoke.

This stud has a central vertical bore for the passage of the conductor wires, the upper portion of the bore being threaded to receive the exteriorly threaded stem 18 of the ornamental loop 19, to which the chain 20 for suspending the fixture is attached. The-stem of the loop is hollow to permit-the passage of the wires.

The lamp receptacle 21 is supported against the under side ofthe horizontal top 10 of the yoke in any suitable manner, preferably by screws 22, which pass through holes in the top 10, provided at either side of the stud 16, for that purpose.

, 23 denotes a bell-shaped shell of any desired ornamental form provided at its bottom with the customary skirt 24 and annular bead 25. The top of the shell 23 rests upon the top 10 of the yoke being provided with an opening for the passage of the stud 16. The beaded lower edge of the shell 23 rests upon the top surface of the globe or shade 15 so that the glassware is held between the bottom of, this shll and the horizontal portions 14 of the yo e.

use, it is seldom necessary to lock the shell in place upon the glassware, but when usedl threaded, and a lock nut 26 screwed thereon down upon the top of the shell 23 as shown in Fig.

We prefer, however, instead of forming a continuous thread upon the stud 16, to cut it away on two opposite sides of the stud providing vertical grooves 27 as shown most clearly in Figs. 5 and 6, and to provide oppositely placed threaded vertical lugs 28 upon the top of the shell 23 for engagement with the spaced sections of thread upon' the stud 16, these lugs passing into the grooves 27 when the stud is pushed through the opening in the top of the shell in connecting the shell to the yoke. When the top of the shell comes into contactv 'With the top of the oke, it is only necessary to give either the s ell or the yoke a partial rotation to bring the threads Where the fixture is employedfor indoor ythere held by tightening the screws 33.

on the lugs into engagement with the threads on the stud whereby the shell and yoke are held together. In order however to prevent any chance of accidental separation of the shell and yoke, we prefer to employ a ring nut 29 which is screwed over the stud 16 down upon the top of the lugs 28. These lugs may be secured to the shell by solder or in any other suitable way. i

While in Fig. 1 we have shown the lamp receptacle 21 fixed to the yoke and so hereinbefore described it, it is sometimes desirable to be able to adjust the lamp relatively to the globe for focusing purposes, and to provide means for so doing we employ an adjustable bracket 30 composed o f a flat strip of metal with upturned ends 31, of a size to t between the sides 11 of the yoke in each of which side is formed a vertical slot 32 through which pass short set screws 33 the ends of which enter threaded holes in the upturned ends 3l of the bracket 30 whereby the bracket may be raised or lowered to the desired position rsid e horizontalbottom of the bracket 30 is provided with holes for the passage of screws for holding the lamp receptacle against it. This construction is illustrated in Figs. 2 and 3 of the drawing. It will be readily understood that the receptacle 21 may be easily transferred from its fixed position on the oke to position on the bracket, or that the racket may be swung out of the way of the lamp when the lamp is connected wit-h the receptacle fixed to the yoke. The bracket may be easily detached from the yoke simply by removing the screws 33, or without the removal of the screws by drawing the screws through downwardly inclined open ended'slots 34 connected with the slots 32 at their upper ends. This is illustrated in Figs. 2 and 3.

In Fig.-7 of the drawings we have illustrated our invention applied to a ceiling fixture. In. this connection we employ a strap 35 preferably formed from a flat strip of metal provided with an opening through which passes the ordinary threaded tube 38 in the outlet box 39, a lock nut 40 being screwed over the threaded tube 38 up against the strap 35 to hold the strap in place against the ceiling 41. This lock nut 40 may have a knurled outer surface, or be of hexagonal shape for engagement by a wrench. The stud 16 on the yoke is screwed. upon the tube 38 thus supporting the yoke and connecting it with the outlet box. The lower part of the shell 42 is of the same shape as the lower part of the shell 23 and for the same purpose, but the top of the shell 42 is open for the passage of the yoke therethrough. Asis customary in ceiling fixtures we employ a canopy 43, but which is so connected that free access to the outlet box and wires at such point may be had without the removal of the canopy or the fixture.

`bottom of the canopy disturbance of The lower open end of the canopy 43 is of slightly larger diameter than the neck 44 of the shell 42 over which it fits.

The canopy 43 is held up against the ceiln' ing by screws 45which pass through holes in the strap 35, and project through holes in the upon which projections are screwed ornamental knobs or nuts 46.

It will be apparent that by removing the knobs 46 from the screws 45 the canopy 43 will dropv or may be lowered until its lower end rests upon the shell 42 thereby leaving an open space between the top of the canopy and the ceiling permitting access to the outlet box and wires for the purpose of connecting the wires or for repairs.

We cla-iin as our invention:

1. In a lighting fixture, a globe support comprising a yoke consisting of a single flat strip of material shaped to form a horizontal top with depending sides having outsturned lower ends adapted to enter the mouth ofthe globe at opposite sides thereof, a lamp recep tacle xed to the underside of the horizontal top of the oke, and a shell covering the yoke and seate upon the outer surface of the globe.
