c. DOANE LIGHTING FIXTURE Filed Dec. 9, 1925 INVENTOR Le/"3 pad/7e i ATTORNEY Patented Oct. 8, 1929 UNITED STATES LEROY C. DOANE, OF MERIDEN, CONNECTICUT, .ASSIGNOR TO THE MILLER COMPANY OF MERIDEN, CONNECTICUT, A CORPORATION OF CONNECTICUT PATENT OFFICE I LIGHTING FIXTURE Application filed December The present invention relates to lighting fixtures, and is more particularly directed toward lighting units having shades which are supported about a single lamp socket.

An object of the present. invention is to provide a shade holder for lighting fixtures which is suitable for releasably supporting a shade or globe, and preferably wherein the shade, the holder and a socket cover may be bodily moved relative to the socket without disengaging the shade from'the holder.

Another object of the invention is to provide a shade holder which is made up out of a small number of simple sheet metal stampings suitably fastened togetherso that certain of them may be bodily moved with the shade without releasing the shade.

In certain types of enclosed lighting fixtures, it is desirable to be able to lift the glass shade or globe so as to provide access to the interior of the glass unit for cleaning the same and to facilitate lamp renewals, and the present invention also contemplates a shade support which permits raising the shade as well as the provision of a removable closure suitable for use in an opening in the bottom of the enclosed glass unit.

In the, accompanying drawings, there is view showing the construction of the shade holder, the socket cover being raised;

Figure 3 is a sectional View along the line 3 3 of Figure 1; and

Figure 4 is a plan View of the closure, showing it removed from the enclosing unit.

, 'The lighting fixture is supported from a conventional loop 10, which is threaded onto the upper end of a tubular stem .11. The lower end of this stem is threaded asshown at sw'edged together,

12, and a bushing 13 is threaded onto it. This bushing supports a spider 14, which may be suitably attached by passing it over the reduced lower end portion of the bushing,and

wardly alongside the socket 17 and are spaced a short distance outside the socket. These straps, of which there are preferably three, pass through holes 21 in a ring 22. This ring is riveted inside the skirt 23 of a socket cover 24, as indicated at 25, so that the ring and socket cover may be, moved as a unit. The upper part of the socket cover 2 1 is drawn inwardly and is provided with a hole 25, slightly larger in diameter than the outside of the bushing. 13. The outside of this bushing is threaded as indicated at 26, and a knurled threaded nut'27 is threaded down onto the bushing so as to hold the socket cover in place, as shown in Figure 1. Y

The lower ends of the straps 19 are bent outwardly, as indicated at 28, so as to pass into the hole 29 in the upper end 30 of a glass shade or bowl G so as to support the same. As here shown, the bead 31 on the lower end of the socket cover is adapted to pass down about the outside of the upper end of the shade.

In making up the shade holder above described, one may rivet two of the straps .19 onto the spider 14 and then pass these straps through the holesin the ring 22, after which the other strap is passed through the hole in the ring and riveted to the spider. The bushing 13 and spider 14 may then be i and the socket cover-placed in position and riveted to the ring 22. a

'VVhen it is desired to, attach a shade to the shade holder above described, it is merely necessary to unloosen' the-knurled nut 27, and raise the socket cover upwardly, as in- ,dicated in Figure2. One may then pinch the lower ends of the straps inwardly, as indicated in dotted lines in that figure, 'so as to permit the shade to pass by. The socket cover is then slid downwardly along the stem, being guided by the straps 19 in the holes 21, the bead 31 being brought against the upper side of the glass and clamped in place by turning the nut 27 onto the bushing 13. The lower ends of the straps 19 are prevented from moving inwardly by the ring The projecting part oi these straps is so still as to be substantially rigid.

When the shade holder is used in lamps of a type in which it is desired to bodily litt r the glass bowl, it is merely necessary to loosen V the nut 27 and raise the bowl. This will cause a socket cover to slide up along the straps, as before. As, however, the upper edge of the bowl will remain inside the skirt of the socket cover, and as there will be no tendency to spring the straps downwardly, there will be no separation of the bowl from the supporting straps. The socket cover will freely slide up and down as the shade is raised and lowered, as the spring fingers 19 will not at this time be pressed tightly against the walls oil the holes 21 in the ring 22. The position of the globe and socket cover when raised is indicated in dot and dash lines in Figure l.

The lower end of the globe G is open, as indicated at 40. A ring 41, which may be in the form of a sheet metal stamping, is of the proper size to fit outside the opening in the globe. This ring has an inwardly directed flange i2, oiiset as shown at as, to provide a shelf 44 and supports a glass disc as. The flange 42 carries a fixed finger l6 riveted to it, as indicated at 47, which finger is of the proper configuration to pass up over the glass, as indicated. A second finger 48, shaped somewhat similarly to the finger at), is pivotally mounted on the flange 4:2 by a rivet 49. This figure 4:8 is part of a sheet metal stamping 50, which extends for some distance above the flange 42, and which has a linger grip 51, which passes out through a hole in the stamping all, so that one may grasp the finger grip 51 and pull it outwardly, thereby moving the finger 48 invurrdly, so as to release the closure member. The movement of the movable linger is limited by an upwardly bent prong 52 which engages with the wall of the stamping. The glass disk 45 is held in place by a number of clips 53, which are soldered to the flange 42.

It is obvious that the invention may be embodied in many forms and constructions within the scope of the claims and I wish it to be understood that the particular forms shown and described are but a few of the many forms. Various modifications and changes being possible, I do not otherwise in any way limit myself with respect thereto.
