(Cl. 240-73) tions having interengaged parts so that the sections may be held assembled by a single screw or other fastener, some portionof the interengaged parts being adapted to coactwith the bead on the neck of the shade in order that the latter may be held on the bracketby a single screw.

One object of the invention is to provide an improved lighting fixture composed of only two sections which'have interlocking parts so that when the sections are assembled only one screw rivet or similar fastener will be necessary to provide a sturdy assembly.

'Another object is to provide on the rear or base-section of the fixture a projectionor projections adapted to not only hold one side of the socket and globe carrying section but also to coact with the bead or groove on the neck of the globe and thus help in holding the globe so that only one globe screw will be needed.

Another object is to provide a fixture of this character which will effect savings both in materials and in assembly time, since the two sections may be molded of phenolic resin or similar insulating plastic material, are quickly and easily assembled and are securely fastened together by the use of a single fastening screw. 1

With the above and other objectsv and advantages-in view, the invention resides in the novel combinations and arrangements of parts and the novel features of construction hereinafter described and claimed, and illustrated in the accompanyingdrawings which show the present preferred embodiment of the invention.

In the drawings: 7

FIG. 1 is a vertical sectional view through a wall fixture and a portion of a globe mounted thereon, parts being in elevation and parts broken away;

FIG. 2 is a bottom view of the fixture, the globe being omitted; V

FIG. 3 is a bottom view of the main or base section of the fixture;

FIG. 4' is a rear view of the base section;

FIG. 5 is a top view of the lamp and globe carrying section;

FIGS. 6 and 7 are detail sectional views taken on the lines 6-6 and 77 respectively in FIG. 2, on an enlarged scale. I

Referring more in detail to the drawings, the numerals 1i}? and 11 denote the two sections of the fixture, each of which is preferably molded in one piece from a moldable plastic insulating material such as phenolic resin. The

main or base section Iii is of generally right angular but as shown there is a centrally positioned screw 14 threaded into a hole at the center of a slotted cross bar 15.

The arm 13 is formed with a passageway 16 for electric conductors but as shown it is hollow with its inner end opening through the plate 12 and its outer end 17 is closed. Viewed from the :top the arm 13 is outwardly tapered and it comprises forwardly converging upright side walls 18 with reduced outer portions, a short flat bottom wall 19 connecting the inner portions of the side walls, the end wall 17 and a top wall 20 which may he stepped or ribbed as shown to make the bracket more attractive in appearance. The passageway or chamber 16 in the arm 13 also opens through the bottom face of the arm and that opening is closed by the other section 11 of the fixture.

The preferably removable section 11 is adapted to carry an electric lamp 23, shown in dotted lines, and a surrounding light diffusing globe or shade 24 which may be of any desired shape buthas the usual reduced annular neck with a peripheral groove or bead 25. The section 11 comprises a pan-shaped body with a preferably flat and circular top wall 26 surrounded by a circular depending side wall or rim 27 of a size to receive the neck of the globe, as shown in FIG. 1. The bottom edges of the side walls 18 are cut away from the front end wall 17 to a point adjacent the short bottom wall 19 to receive the major portion of the section 11; and the upper surface of the top wall 26 of that section abuts those bottom edges while, as shown, a portion of the circular rim 27 abuts the arcuate front edge 29 of the bottom wall 19 of the bracket, as will be seen upon reference to FIGS. 1 and 2.

In order that a single screw, rivet or similar fastener 30 at the outer portion of the hollow arm 13 may be usedto hold the sections'ltl and 11 assembled, an interengaging connection between the two sections is provided at their inner or rear portions. That connection may take various (forms but comprises one or more projections on the bottom wall 19 to at least underlie some portion of the rim 27. As shown there are two upstanding ribs 31 formed on the top of the wall 19 in laterally spaced relation and extending in a forward and rearward direction,

the outer projecting ends 32 of the ribs extending through spaced notches 33. formed in the lower edge of the rim or wall 27'. The projection or projections 32 are disposed at the side of the section 11 opposite the location of the screw 30 which passes upwardly through a hole 34 formed in the top wall 26 and is engaged in an internally screw threaded hole 35 formed in the bottom of the thickened outer end 17 of the arm 13 of the bracket. To strengthen the hole 35 the inner or rear side of the end wall 17 is formed with an upright enlargement or rib, as seen in FIG. 4. The threaded hole 35 is preferably molded in accordance with the disclosure in the Baxter et al. Patent 2,775,916, January 1, 1957. To further strengthen theconnection of the two sections 10 and 11, the screw 30 extends through an upwardly projecting circular boss 36 formed on the top of the wall 26 and adapted to seat in a similarly shaped socket 37 in the bottom of the end wall 17 concentric with the threaded hole 35. In assembling the two sections the pan-like section 11 is tilted to engage the tongues or projections 32 in the notches 33 and the outer portion of that section is then swung upwardly against the bottom edges of the side Walls 18 so that the boss 36 enters the socket 37. A

' screw, rivet or similar fastening may then be inserted and shape when viewed from the side and comprises a prefertightened to hold the sections interlocked and provide a sturdy assembly.

As previously noted, projections 32 also coact with one or more screws in holding the globe 24 on the section 11, a single screw 40 being preferably used. To accorn plish that additional function the projections 32 are made sufficiently long to extend into the groove in the neck of the globe and engage under the head 25, as shown in FIG. 1. The screw 40 is threaded in a hole formed in the rim 27 at a point substantially diametrically opposite the projection or projections 32, and its end projects under the bead 25. By thus using the projections it is only necessary to provide one screw 40 to hold the globe and one fastener 30 to hold the fixture assembled. I

Molded at the center of the top wall 26 of the section 11 is the body 41 of an electric light socket to receive the screw threaded plug of the lamp 23. This socket is a cylindrical upright shell molded integrally with the wall 26 and has a top 42 which projects slightly above the' top of that wall. The lamp socket is of the usual con-, struction as seen in FIGS. 6 and 7. It comprises the usual internally threaded metal shell 43 and the metal center contact plate 44. Positioned in the top wall 42 are three

metal eyelets

45, 46 land 47. The eyelet 45 fastens the center contact 44 and in its top may be soldered one of the electrical conductors. The contact 44 is a generally rectangular strip of metal set in a channel in a thickened portion of the wall 42. The other two eyelets 46 and 47 extend through the spaced top portions of the metal shell 43 to fasten it. In one of the eyelets 46, 47 may be soldered the other electrical conductor. These conductors 48 extend through the chamber or passageway 16 in the arm 13. The plastic insulating body portion 41 of the socketmay be reenforced or strengthened by upright ribs 49 molded on its outer surface below the wall 26.

From the foregoing, taken in connection with the laccompanying drawing, it will be seen that novel and advantageous provision has been made for carrying out the objects of the invention, and while preferences have been disclosed, attention is invited to the possibility of making variations within the scope of the invention as claimed;
