At the interior of the fixture, and at suitable points at spaced intervals throughout the length thereof, is a combined n'nillion and wiring box 1.7. This element is of substantially rectangular formation, and is in the form of a frame, one or more oi these rnullions being employed in accordance with the length of the fixture, =d each being designed to brace the fixture and to afford proper sup port for thetront and rear walls and As seen in Figure 6, the baseot the element 17 has a transversely extending head 18 formed thereon, the edges of the base at opr s" .i sait. cad 'mhlig sacs Jone scles ot l b lT l l e t to support the contiguous ends of the glass panels 16. At the upper end Oil: the element 17 is a boxlilre receptacle l9,'which consti tutes a wiring box. The opposite walls it the receptacle 19 are provided with gned openings 20 at the exterior oi each of which is arranged'a hublilte flange 21. The openings 20 receive the bases of oppositely projecting insulated lamp sockets 22 which seat against said flanges 21, and are sutahly sc cured in these openings to support the necessary lan'lps tor giving the requisite illumination to the fixture. To eaco. ot the sockets 22 there is suitably connected a supporting trains 23 for reflectors tor the several lamps, said frames 23 being provided vith slotted attaching; ears 24 which cooperate with t'astening screws 25 through the inediun'i of which the sockets 22 and the frames 23 are secured to the flanges 21. r

The opposite sides of the walls of the re ceptacles 19, at the end portions thereof, are provided with oppositely disposed attaching lugs 26, said lugs 26 each. being provided with an elon ated slot 27 for receiving iiasteningig screws .28, and the horizontal flanges of the rectangular offsets 12 of the front and rear walls 10 and 11 seat upon said lugs 26 and are secured thereto by the bolts @bvi- -JL: ously, the slots 27 afl'ord adjustment of the bolts to provid for adjustment of hllO side walls 10 and 11. in relation to the element 17. The upper. edges of the walls of the receptacle 19 are also provided with aligned notches 29 into which are titted the ends of flanged wirewaysor troughs 30 wherein are positioned the electrical conductors included in the wiring connections of the lit re. While affording access to the Wiring connections from the top oi": the fixture, the wire ways 30 conceal these connections the in terior of the fixture, so that the wiring-3, connections are not exposed at such interio I Each side wall of the receptacle l9 h s a verticalrib 31 at its exterior, and to out: ot saidribs 31 is connected :1 fastenin new 32 which penetrates, cover plate 33 tin ou h the medium of which the top of the fixture is closed. This cover plate 03 has depending marginal flanges 3% which tit over the upwardly extending flanges 1d of the front and rear walls 16 and 11, thereby presenting a finished joint at these points, and effectually concealing the flanges 14 from view. ()bviously, the plate 33 covers the wireways 30, so that uccessto the interior of these wireways cannot be had except upon removal of the cover plate lVithin the receptacle 19 is located also a suitable switching device 35. This may be of the pull chain type, or it may be of any other approved construction. This switch ing device controls the wiring connections for switching on and oil the several lamps connected to the various sockets 22.

At the terminal portions or the fixture are located end caps 36. These caps also are of paneled formation to impart an ornate appearance to the ends of the fixture, and the sides and bottom oi paid caps 36 are provided with inwardly extending flanges 37. Ateach corner each of the caps 36 is a rectangular oillset socket 38 wherein the upper andlower otlsots 12 and. 13 of the front and rear walls it) and 11 are seated. This is clearly illustratcd Figures l and 7. l Vithin the lower socket.) are provided inwardly extending anchoring lugs 39 between which and the wa ls of the sockets 3d the otl'sets 13 snugly lit, while the upper sockets 38 are likewise provided with inwardly exten ding flanges s'l) between which and the walls of the upper sockets 38 the offsets 12 are snugly fitted and anchored. By the connections ust described the end caps 36 find frictional engagement with the front and rear walls 10 and 11, but to secure the latter permanently to the end caps 36 bolts 41 are provided.

The head or each of the upper soclnats 38 is also grooved, as 42, for the reception of the upwardly extending flanges 14-, of the front and rear walls 10 and 11, whereby a further interlocking engagement of? the Walls 10 and 1.1 with the end caps is el'lected.

At the inner side of the head of each oi? the er l caps 36 is located a boxlike receptacle said receptacle constituting a wiring box, and the inner wall. thereof has an opening e l therein which is surrounded by a hublihe e 45. The opening 4' receives one 0t 1 1e insulated lamp bases p1 musly (leso. ihcd :1 oil secured therein a so in the mannor here..ibctore set forth. he up; 181, edge of said inner wall of the receptacle .8 there is also provided flanged notches 46. Where only one wireway 30 is employed. illustrated in Figure 1,? and 8. one o f the flanged notches 46 receives the end of that wireway,

thus affording communication between the interior ot the receptacle i?) and the wircway 30. In such event the other flanged notch 4a; is closedby the CllSjillitCeillOle closure web 47 which is seated in a groove 48, one of. these grooves being formed in each of the flanged notches 46. By the provision of said notches 46 either of the same may be select-ed for locating the wireway 30 at either the front or the rear of the fixture, or both of the same may be utilized, if it be desired to employ wiring connections for which one of the wireways is not suflicient.

At the exterior of the inner wall of the receptacle a3 is positioned a vertical rib 49 to which one of the fastening screws 32 is connected. thus providing means at the terminal portions of the fixture for holding the covering plate 33 in lixed relation to the end caps.

At the lower face of the base of the combined mullion and wiring box 17 is provided a pair of grooves 50 into which the flanges 15 of the walls 10 and ll are designed to fit so as to afford further anchorage of these walls with respect to the element 17.

It will be noted that the glass panels 16 are of greater width than the opening between the flanges 15 in order to overhang these flanges and be supportml thereby. and the ends of the panels 16 which lie contiguous to the end caps 36 rest upon the bottom flanges 37 of these caps. If it be desired to gain access to the interior of the fixture such may be easily accomplished by slightly elevating the end of the panel which lies adjacent to the head 18 of the combined mullion and wiring box, whereupon the panel may be moved over the bead, as illustrated by dotted lines in Figure 2. This permits access to the interior of the fixture for such purposes as may arise, as for re-lamping the fixture.

In the use of the herein described fixture the same may be supported from the bank screen by any suitable means which will clevate the fixture above the working plane of the desk or desks to be illuminated. The glass panels 1 6 afford a diffused light which is directed immediately upon such working plane. Direct illumination thus is afforded. But in some circumstances it may be desirable for utilizing the fixture for indirect illumi nation, in which event as shown in Figure 9, the cover plate 33 may be provided with openings 51 at suitable points so that the rays of light from the lamps opposite these openings may pass out through the latter. In such construction the reflectors will be turned so as to direct the rays of light upwardly rather than downwardly, and this arrangement may be followed so that alternate lamps with their reflectors will project their rays through the top of the fixture, while the others project their rays downwardly through the glass panels 16 T he herein described invention provides a fixture of sectional character which may be readily assembled, the parts beinr so organized and inter-related as to permit their fitting together with ease and minimum expense, and their production by instrumentalities and methods of manufacture entailing but little labor in such production.
