ELECTRIC-LAMP FIXTURE.

To all whom it may concern I Be it known that I, THYGE NELSEN, a citizen of the United States,residing at Chicago, inthe county of Coo-ka'nd State of Illinois, have invented certain new and useful Improvements in Electric-Lamp Fixtures, of which. the following is a specification. I

This invention relates to bracket fixtures for securing electric lamps to' a wall-or other support, and its object is to provide a fixture of this kind which is simple in construction, which will securelyhold the lamp, andwhich canbe easily'and cheaply installed. This object-is attained by means of a novel combinationand-arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is an elevation of the fixture,

I partly in section, and broken away. Fig, 2

is a horizontal section on the line 22 of Fig. 1. j

Referring specifically to the drawing 10 denotes a canopy such as is usually em ployed in connection with lighting fixtures, said canopy other support inwhich latter is embedded a stem 12 which projects and has its pro jecting end screw-threaded. The horizon tal'arm 13 of a lamp bracket 14 extends centrally through the canopy and is screwed-on the projecting end of the stem 12, the latter being located centrally inside/the canopy. Set screws 15 threaded through theouter portion of the canopy against the arm 13 secure the canopy in place. The canopy is slidable on the arm, after loosening the set screws, and it is thusadjustable independout of the threaded connection between the arm and the stem 12. The main body of the bracket 14 is a hollow drum of any suitable design having alined top and bottom openings 16 and 17, respectively. On the top of the bracket, over the opening 16, is mounted a globe and lamp support 18 having an outstanding wide'top flange 19 for supporting a globe 20 which incloses the lamp 21. The flange 19 has an upstanding marginal rim 22 which surrounds the base of the globe and carries set screws 23 engageable with said globe for holding the The globe seats on the Specification of Letters Patent.

flange 19, and the latter has, adjacent to the rim 22, segmental grooves 24 in the-bottom of which are apertures 25 opening through the bottom of the flange. The purpose of the grooves and the apertures is to permit the escape of any water which may get on the flange, especially that which runs down the outer-surface of'the globe and gets between its base portion and the rim 22.

The support 18 has a downwardly tapered vertical recess 26 to receive the socket 27 of the lamp 21, the latter being an ordinary incandescentlamp. The recess opens through the'top of the support and has atop countersink 28. The lower portion of the recess is reduced in diameter and screwthreaded, andf'opens through the base of the support and is in ,line with the opening 17. Through the center of the drum passes a stem 29, the upper end of which passes through the opening 16 and is threaded to screw into the lower. portion of the recess 26.- The lower end of, the stem extends through the opening 17 and projects therefroma sufficientsdistance'to hold an ornamental tail piece 30,'the latter being screwed I on the projecting portion of the stem against the bottom of. the bracket body 14. The tail piece therefore serves'as a nut to 'hold the s'tem'29 in place, andthe latter. in turn, holds the support 18.

The socket 27 has a slight downward taper so that it may be tightly wedged in the recess 26, in which it is held against upward displacement by rings 31 and 32-. The ring31 is wedged tightly on the socket by being driven toward the larger end thereof. The ring 32 is located between the ring 31 and a shoulder 33 on the socket, and has apertures to receive screws 34 which are screwed into the bottom of the countersink 28, in which latter the rings seat.

The lamp wires 34 pass through the stem 29,- thesame being tubular. The arm 13 is also tubular to. accommodate the wires, thev stein having aside opening 35 through which the wires pass to the arm. The arm has a side opening 36 through which the I screwed. on the ing means described, and the invention effectually serves the purposefor which it is designed.

I claim:

1. A lamp fixture comprising a bracket, a

stem extending from the bracket and having a projecting threaded'end, a lamp support projecting end of the stem,

, the opposite end. of the stem being also stem.

A lamp fixture comprising a bracket, a lamp support carried by the bracket, said support having a tapered recess WhlCh is countersunk, a tapered lamp socket seating in the recess, a ring wedged on the socket and seating in the aforesaid countersink, a second ring encircling the socket, the latter having a shoulder, between which shoulder and the first-mentioned ring the second rin is located, and means for securing the second ringin the countersink.

7. A lamp fixture comprising a bracket having a hollow body portion and a tubular arm, a tubular stem passing through the body portion of the bracket and having a side opening thereinto, said stem projecting from the ends of the bracket, the projecting ends being threaded, a lamp support secured on one projecting end of the stem, and a nut secured on the other projecting end of the stem.

In testimony whereof I afiix my'signature in presence of two witnesses.
