FLUORESCENT LIGHT FIXTURE Filed Sept. 4, 1952 2 Sheets-Sheet 2 United States Patent FLUORESCENT LIGHT FIXTURE Edward F. Zurawski, Chicago, Ill., assignor to Garden City Plating & Manufacturing Co., a corporation of Illinois This invention relates to a fluorescent light fixture having two or more fluorescent tubes, and has particular reference to means for simplifying the assembly of the component parts thereof.

In accordance with the present invention a pair of lugs is struck out from each end plate and the ends of the side walls of the reflector are each juxtaposed against one of said lugs and secured thereto by means of a single screw. The four screws may be easily applied and comprise a very simple means for securing the reflector in place. A socket retainer is secured to the end plate adjacent each side of the reflector by means of a single screw. Each socket retainer is adapted to position and hold one or more sockets in place.

The structure of the present invention by means of which the above and other advantages are attained will be described in the following specification, taken in conjunction with the accompanying drawings, showing a preferred illustrative embodiment of the invention, in which:

Fig. 1 is a side elevational view of a four light fixture embodying the invention;

Fig. 2 is a bottom elevational shown in Fig. 1;

Fig. 3 is a perspective view of an end plate;

Fig. 4 is a fragmentary perspective view of the reflector;

Fig. 5 is a fragmentary perspective view of one end plate showing the socket retainer and one end of the reflector secured to the end plate.

Fig. 6 is a view similar to Fig. 5, with the socket retainer omitted and the sockets shown in dotted lines;

Fig. 7 is a detail perspective view of the socket retainer;

Fig. 8 is a detail perspective view of the socket; and

Fig. 9 is a fragmentary cross sectional view, showing the socket retainer and two sockets in position.

In the drawings, the reference numeral 2 indicates an end plate having side flanges 3 and a top flange 4. The lower end of each side flange is extended inwardly, as indicated at 5, to form a base for side plates (not shown) which may be used or not, as desired. The top flange is provided with a pair of threaded apertures 6, for a purpose hereinafter described. Two lugs 7 are struck from the end plate and extend forwardly at right angles from the end plate. The lugs 7 are symmetrically arranged and extend angularly relative to each other, the lower end of each lug being positioned closer to the center of the end plate than the upper end. Each lug is provided with a threaded aperture 8.

The reflector 9 comprises a top wall 10 and integral side walls 11 of symmetrical angular configuration depending therefrom. Each side wall is bent inwardly from the lateral edge of the top wall, then downwardly in a vertical plane, outwardly and then inwardly, as indicated at 12, 13, 14 and 15 respectively. The lowermost sec tion 15' of the side wall is parallel to the lug 7 and is juxtaposed against the lug when the reflector is assembled view of the light fixture 2,753,444 Patented July 3, 1956 with the end plates. A threaded aperture 16 is provided adjacent each end of section 15 and a screw 17 is threaded through the registering apertures 7 and 16 to secure the reflector 9 in place with the end of top wall 10 engaging the underside of top flange 4.

The socket retainer 18 comprises a flat bottom 19 having an upstanding side flange 20 and an. end flange 21'. The side of bottom 19 opposite the flange 20 extends outwardly, as indicated at 22. The adjacent end of flange 21 is extended to meet the end of lateral flange 22 to form a closed end portion 23 shaped to fit adjacent the side wall 11 of the reflector. When the socket retainer 18 is assembled with the rest of the lighting fixture structure the end 23 fits against the side wall portions 12 and 13 of the reflector so that the reflector and socket retainer furnish mutual support for each other. The bottom 19 of the socket retainer is provided with an aperture 24 which registers with aperture 6 in top flange 4 and a screw 25 extending through aperture 24 is threaded into aperture 6 to hold the socket retainer in place.

In the drawings the socket retainer is shown as having two recesses 26 in the bottom 19 for holding two sockets 27. It is obvious that the number of recesses 26 may be increased to provide for additional sockets, and the number of sockets is limited only by the width of the fixture. The flanges 2t? and 21 space the bottom 19 of the socket retainer from the top flange 4 of the end plate.

Each socket 27 has a base 28 and a projecting portion 29 of less width and thickness than the base. The height of base 28 is substantially the same as the flanges 2i) and 7.1 so that the base fits between the bottom 19 and top flange The offset portions 30 of base 28 rest on bottom 19 and the portion 29 projects through recess 26. The engagement of top flange 4 and bottom 19 against opposite surfaces of socket base 28 retains the sockets 27 firmly in place. Each projecting portion 29 of the socket is provided with a recess 31 to receive one end of a fluorescent tube 32 and to provide suitable electrical contacts therefor.

Although I have described a preferred embodiment of my invention in considerable detail, it Will be understood that the description thereof is intended to be illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of the appended claims. Accordingly, I do not desire to be restricted to the exact structure described.

I claim:

1. In a lighting fixture, an end plate, a flange extending inwardly from the top edge of said end plate, a reflector having one end secured to said end plate, said reflector having side walls of angular configuration, a socket retainer having one side shaped to conform to the angular configuration of one side wall of said reflector, the entire outer surface of said one side of said retainer engaging said one side wall of said reflector, whereby said retainer and reflector furnish mutual structural support to each other, said retainer having a bottom spaced from said flange and secured thereto in spaced relationship to permit retention of the base of a socket between said bottom and said flange, said bottom having a plurality of recesses adjacent said end plate, each of said recesses having a surface area smaller than the cross sectional area of said socket base and fitting the cross sectional periphery of a portion of a socket projecting from said base through said recess, and a portion of said bottom contiguous to each of said recesses being adapted to support the base of a socket to hold said socket against said end plate.

2. In a lighting fixture, an end plate, a flange extending inwardly from the top edge of said end plate, a reflector having one end secured to said end plate, said reflector having side walls of angular configuration, a socket re tainer having one side shaped to conform to the angular configuration of one side Wall of said reflector, the entire outer surface of said one side of said retainer engaging said one side wall of said reflector, whereby said retainer and reflector furnish mutual structural support to each other, said retainer having a bottom spaced from said flange, said bottom having a plurality of recesses adjacent said end plate shaped to receive individual sockets each having a portion projecting through one of said recesses and a base of larger cross sectional area than said recess, said bottom being spaced from said References Cited in the file of this patent UNITED STATES PATENTS 2,249,318 Locke July 15, 1941 2,534,182 Schwartz et al.
