socket substitutedtherefor, without dissocket 12 can be detached from the shade holder to remove the same, and another mantling the fixture.
As shown in Figs. 1 to 3, inclusive, the
tact 28, andhaving a radial flange 30 adapted to engage Withthe lower end 26". ofthe upper part 26. In the case of such a-lamp 1 socket, in order to provide the grooves .for
. engagement with the supporting setvscrews 24, 24, 24, of the shelllO, as above described, we provide a metallic shell 31 adapted .to surround the upper part 26 of the lamp socket and'secure said shell to the lamp socketby means of an inwardlyprojecting radial flange 31? formed atthel bottomof said shell 31, and adapted to becIamped between the lower end 26. 9f the upper part 26 and the radial flange 31 of the ring 29. (See Fig. 3). The annular grooves 22 are formed in said shell 31. V t i i 1 When a lamp socket is especially'designed forthe fixture, we form the longitudinally spaced annular rooves directly in. the, in-.
sulating body 0 the socket, as shown inv Rig. 4- In said figure, 12 indicates a lamp socket of insulating material having longi v tudinally spaced annular-grooves 22 22,
formed in its outer surface, and the socket is secured and supported within the tubular r' mime? shell 10 by the supporting set-screws 24. engaging Within one ofsaid grooves 22, 22',
as before described. 25, 25 indicate the vertically extending transverse shoulders provided to form stops for the purpose, before described." It is obvious that any number of said longitudinally H grooves may be formed in the lamp socket and any degree of adjustment of the same within the tubular shell be thus provided for.
We claim as our invention g An electric light fixture comprising a tubular shell, a lamp socket located therein and capable of adjustment lengthwise of said shell, said lamp sockets being provided with .longitudinally spaced, annular grooves formed'in. its outer surface, means for securing said socket at one of a plurality of predetermined longitudinally spaced posispaced annular done in said shell, said'means comprising.
annularly spaced set screws pro ecting.
through the tubular shelland adaptedto engage Within. one of the annular grooves in said socket, and a shade supportingmemher locatedbelow said tubularshell and I made integral therewith.
In testimony, that we claim the foregoing as our invention we affix our. signatures in of October A. D. 1911. I
