blage,' and because ofthe 'work 'to be doneon each individual part of the device. The

primary object of this invention' is to prof vide for a simple assemblage of parts which may be made very cheaply and which may be readily attached to the support. Another object isto provide a single piece. insertible 4`body portionl adapted. to be secured to the support, and surrounded by a thin metal sleeve, which sleeve maybe finished or decorated inl any desired manner, thus providing a 1lighting fixture which shall have a handsome appearance, andA yet its cost of constructing is extremely lowas compared with itsl appearance. Another' object is to provide an'insertible body .portion completeV in itself, which may be sold to the trade as an article of merchandise readyto be covered by a shelll or cover. With these land, other objects in view, this invention consists in the several novel features of construction, arrangement and combination of parts hereinafter fully set forth and claimed..

The invention is clearly illustrated inthe drawing accompanying this specification, in which Figure 1, is a' view partly inside elevation and partly in central vertical section throilgh a lighting fixture embodying a simple form of the present invention; Figs.

2, 3, and 4:, are side views of the supporting fixture disassembled; Fig. 5, is a side View of the main body portion of the device; Fig. 6, is a central longitudinal section of 'a wall bracket forml of the fixture showing the invention applied thereto 7, is a -crosssection taken on the line 747 o f`F1g. 6; Fig.8, is a side elevation of a modified forni lduct'or cords extend out from thel of the invention, and F ig. '9 is a side `,eleva-l tion of a ring seeninl Figs. 1, 6 and?.

Referring first to Figs. 1 to 5, inclusive, v

10, designates a supporting member here shown as Comprisinga crowfoot supporting.

device,A which lis .secured to the ceiling or wall of a room as the case may be, and inI accordance with the usual practice, said supporting member is formed with an intex's nally oreXterna-lly screw-threaded ring 1'. upon whichis screwed the threaded end the fixture.

In its' preferred form the device com? prises an insertibl'e bodyportion 12, having ends; said extensions are .illustrated in the `screw-tlireaded extensions ,13, 14, vonits y the neckgl, beingadapted toA be screwed into the internally screw-threaded ring 11,

of thebcrowfoot support 10. A'lengthwise extending groove 15, is formed in oneyside of the body portion 12, for the reception ofthe conductor cords a, of the lighting lixture and. said groove extends throughout the greater portion of the length of the body :portion 12. The neck 111, has a passageway 1 6, formed therein through whichthe congrocved body portion to the light socket or sockets. Said body portion comprises .two ' integral parts 17, 18,A the part 17, being ofl greater diameter than the part 18, to leave a' shoulder 19; said shoulder forms an abutment place for a thin shell of tubular materiai Q0,

which shell `may be highly finished and.

polished to correspond with the finish of the other fixtures of the room and may be constructed of' brass or of other materials which will'V take a high finish and polish. Said tubular member 20, andv part 17, of the body portion 12, ofthe device. may be of substantially the same .diameter so `that the device may `pass through the opening in the canopy`(seen at 21,). while the device is in an assembled condition.l The canopy is held on the device by a set screw, in the usual, common andv well-known manner. The tubular member Q0, extends from the shoulder portion 19, tothe end of the part 18, ofthe body portion, and is held infplace thereon by suitable means, here shown as comprising a ring or lcop,,having a lianged'portionl 24;, adapted to bear against the adjacent end of the tubular member 20.

'i threadednopening whereby the ring may be .i screwed upon: the neck 14. I may iorm a f assembled quickly and with very littlelabor, l

1n cross section tl,u "oughout the greater kporwhich projects the cof , unscrewing the ring cr loop part 18, through the sh'ell and screwing the -1 ring back upon the neck. X301 flange 24, of thejdevice groove 28a, in the body portion 'at the `shoul' der 19, for the reception of a split ring 28, which ring closes the gap between the sides of the groove 15, at said shoulder. One

ward the center of the ring and inserted 1n an aperture 30,- formed in thebody portion.

u This construction prevents accidental turn-l ing' 'of the ring. The ring is -preferably round 1n cross-section to provide a smooth y surface, thusv preventing any chang of the conductor cords at the place where they emerge from the upper end of the shell 20.

One ofthe'particular advantages t this' device consists in the fact that it may be and'that the device, wit-h the shell or tubular portion omitted, may be sold to the trade as an article of merchandise. l.This

permits the dealerl or person installing the to 'employ shells orvtubular mem- `and said shells first.

device, bers of the desired finish, may be applied to the body portion by 23, inserting the 14, thereby clamping.' the shell between the shoulder ,19, and the loop or ring 23. In wiring pushed through the.

, to the, house wires.

' When used as a wallbracket, as shown in Fig. 6, a ball 25, orother ornamental knob or ornament'may be screwed upon vthe hollow neck 14, to give the end of the device yan ornamental appearance, and an electric lamp socket 26, may be screwed into a transversely extending, 27, which isA formed in the wall of thev part 18, near the end bearing the neck 14. In this instance the external shell 20, .isalso provided with an opening in its side through tric light socket. In wiring-the form illustrated in Fig. 6, the device is disassembled, the wire passed through and laid in the groove', aft'er which the de vice is assembled.- It is to be noted 'that the groove in the body portion 12,1s made 'quite widel and deep so asto facilitate the insertion of the conductor cords through the device. AIn the tubular member 20,I is held in` place by a split ring 23a, the ends of which extend thrbugh apertures the conductor :cords :may bev passageway of the de vice when fully assembled, and when disas j through the ring 23,
