in lighting fixtures for fluorescent Serial No. 354,037 filed by me terial. The ballast housing 4 may be made of glass, plastic'or metal, and in the design shown produces an ornamental effect in conjunction with the horizontally disposed lighting fixtures 3 that house the fluorescent tubes 8.

By providing a separate housing for the lamp ballast, the mounting of the fluorescentv tube inside of the fixture is simplified and consumes less space, thereby affording greater flexibility in the design of the fixture which may be produced I ,in various ornamental shapes.

ing for the lamp ballast outside of the glass fixture.

The invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters. designate like parts, and in which:

Fig. l is aview partially in cross-section and partially in front elevation of a fluorescent lighting fixture embodying the principles of this invention;

Fig. 2 a vertical cross-sectional view thereof; and

-Fig. 3 a cross-sectional view of a fixture employingtwo fluorescent lamps.

' In the drawing,- the' numeral I designates a mounting'bracket which may be a casting having flanges 2 forming a seat for the glass lighting fixture 3'. Attached to the bracket 1 is a housing 4 secured by a threaded nipple 5 and a nut 6, the

, in the flanged portions nipple 5 being hollow for admitting the electrical conduit "I to the thumb nuts l4 bywhich the lighting fixture 3' is held against its seat in the center bracket I.

As shown in Fig. 2, the electrical conduits 1 pass over channels l0 and are fastened to the terminal posts 15 of the'terminals 9 The lighting fixture is of annular shape with the bottom portion l6 fluted to form a refractionating surface for the light, and this portion It may be of a translucent. glass while the remainder of the interior of the lighting fixture. The housing 4 is adapted to be attached to a,

The fixture may be readily mounted by fastening the housing 4 to the wall or ceiling with the center bracket l assembled to the housing and the channel members 10 mounted to the center bracket, as shown in Fig. 1. It is then a simple matter to insert the fluorescent light tubes 8 in their terminals 9 and place the half-sections of the lighting fixture in position by seating them 2 of the center bracket I, and attaching the thumb screws l4. This construction provides accessibility for inspection, cleaning and replacement of the fluorescent tubes.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

.I claim:

1. In a lighting fixture for fluorescent lamps having a ballast, a housing for said ballast, a bracket extending outwardly from said housing and attached thereto, a support for fluorescent lamps secured to said bracket and extending substantially in a horizontal plane, a plurality of translucent lighting enclosures or shades mounted beneath the ballast housing with their inner ends in the bracket, and means extending through the outer ends of said enclosures for attaching the enclosures to the ends of the support.

2. In a lighting fixture for fluorescent lamps, a ballast housing, abracket extending outwardly from said housing andattached thereto, a support for fluorescent lampssecured to said bracket and extending substantially in a horizontal plane,

a plurality of tr'anslucentlighting enclosures or shades mounted beneath the ballast housing having their inner ends shaped to flt in the bracket,
