(Cl. 240-78) The present invention relates to lighting fixdicated at 21 so as to provide a seat 22 for the tures and is more particularly directed toward ininner edge 23 of a deflector 24, preferably made direct lighting fixtures having aluminous central of glass. When this deflector is in place, as portion or disc directly supported from above (as shown, it closes the slots 19 so thatthe supportfor example by a socket cover) and a light d ing chains 16 cannot then be removed from the 60 fiector of larger diameter supported from the censlots. 7 tral luminous disc.

Fig. 1 also shows the use of a metal cap or Th pr n inv n ion n mpl s a fi re cover 25 secured to the disc 18 by a central bolt of this nature wherein the disc is secured to the 26.

The upper comparatively deep sections as indicated at A edge of the disc is preferably shouldered as inthrough which light passes so as to provide a comparatively bright ring of luminous material, of less optical density than the shade 24, thereby adding an effective form of trimming to the fixture.

It will, of course, be understood that the present invention is not necessarily limited to lighting fixtures which are open at the top for it may be applied'to totally enclosed fixtures made with a one piece or a two piece globe open at the bottom. It then provides a convenient means, not only for supporting the shade or globe but for afiording access to the lamp bulb from underneath. It also provides for luminous trimming to the fixture which enhances its appearbodied in many forms and constructions, and I wish it to be understood that the particular forms shown are but a few of the many forms. Various modifications and. changes being possible, I do not otherwise limit myself in any way with respect thereto. 1 4 1 What is claimed is:

1. A lighting fixture comprising a pendant lamp socket, a socket cover about the socket, a lamp bulb in the socket, a translucent disc underneath the lampbulb, the disc having peripheral slots. disc supporting members secured to the socket cover and-passing through'the slots, and a bowl restingon the discand closing the slots.

' 2. A lighting fixture comprising a pendant lamp socket, a socket cover about'thesocket, a'lamp bulb in the socket,;a translucentdisc underneath the lamp bulb,' the disc having peripheral slots, disc supportingmemberssecured to the socket cover and passing through the slots, and a bowl having a bottom opening smallerthan the disc and large enough to receive the supporting members,

the bowl resting on the periphery of the disc and extending upwardly and outwardly.

3. An indirect lighting fixture having a bowl, open at the bottom, a diffusing glass disc havin a peripheral seat to receive the lower edge of the the slots.

4. A lighting fixture as claimed in claim 3, wherein the supporting members are in the form of lengths of bead chain having enlarged balls at the lower end, and the disc has ball receiving pockets.

5. A lighting fixture as claimed in claim 3, wherein the supporting members are in the form of. lengths of resistant wire tensioned to press inwardly.

6. A lighting fixture comprising a diffusing bowl openat the bottom, and a diffusing closure member for the hole, the closure member being provided-- with a thick peripheral edge of less density than the bowl so as to provide a bright ring of light below the bowl.

'7. A lighting fixture comprising a centrally located glass'disc, supports extending from above the disc-down through openings in the disc near its edge and havingenlargements below the disc 4 to support the disc, and a glass diffusing bowl extending upwardly and outwardly fromthedisc,

the bowl having a central aperture to receive the supports, and resting directly on the upper surface of the glass disc.
