LIGHTING-FIXTURE.

Specification of Letters-Patent.

Patented Nov. 2, 1915.

a citizen oi the l'nited' States. residing at Chicago. in the county of (ooh and State of lllinois. have invented an iinprovtunent in Lighting-l' ixtures, ot which the following a specification.

Mvprescnt invention relates to that class of electric lighting fixtures giving a candle eii'ect, in which a porcelain or glass tube or metal cylinder is employ-ed to represent the 'andle. and a metallic cup is attached to a supporting arm ofhracket. into which cup the lower end of the candle is inserted, such porcelain candles and separate metallic cups are employed.

The details of the invention are hereinatter particularly described.

In the accompanying drawing,-l*igure 1 is an elevation slowing my invention attached to a fixture Fig. 2 is a .vertical section.

Similar reference characters indicate like parts in both figures.

1O designates a hollow metallic cylinder formed with a transverse annular rib 11.

The surt'ace'of this cylinder above the rib 11 is coated with a substance to give it a contrasting appearance to the rib and that part 0? the cylinder below the same. The material employed for coating the upper surface of the cylinder may be. of any desired character or color, but I preter to use white enamel. I

12, Fig. 1, indicates the coated or enameled surface of the cylinder. ll'hile my invention is applicable to chandeliers or other lighting fixtures in which a number oi" candles are employed, I have shown it in Fig. 1 as attached to a bracket 13 supported in the ort'linary manner against a side wall 14-. The free end of this bracket .is provided with ascrew threaded stud 15;

where the invention is applied to a chandelier or other fixture requiring a number of candles, arms carrying similar studs are provided on the fixtures.

16 indicates a shallow shell having all-annular concave rim 17. The bottom of this shell 16 has an opening to permit the shell to be placed over the screw-threaded stud 15 on the end of the liiracket.

18 designates a support for a lamp.s0cket, and is preferably tubular to receive the conductor wires, although it may be of any suitable character adapted to be screwed upon the screw-threaded stud 15. lu the form shown, the lower end of the tube is. 'interiorly screw-threaded for such purpose. It will. be readily seen that when this tube 20 indicates small teats or projections on opposite sides of the cylinder 16 ad acent, to e its lower end. This lower end of the cyiinder is received within the annular rim 17 of the shell 16, its bottom edge resting upon. the annular shoulder formed therein.

placing the end of the cylinder within the I accidental displacement.

By reference to Fig. 1 of the drawing, it will be seen that the lower part of the cylinder 10 with its rib 11, has the same outward and ornamental appearance as the metal cup hertofore employed in fixtures of this character, whilethe upper-,part of the cylinder with its coating 12, gives the same candle effect as has heretofore beenproduced by the separate candles and cups heretofore employed. It will be, obvious that'the lower portion of the cylinder, or that part representing the cup heretofore, employed, may be of any desired shape or configuration, so long as its lower edge is adapted to fit into the rim 17 of the shell 16.

By the employment of my invention, the use of glass or porcelain candles is rendered unnecessary; the cups heretofore required are entirely dispensed with, while the same ornamental and candle efiect is obtained. There is no danger of the candles in my device being accidentally displaced, and the same are readily put in position on the fixture, or removed therefrom, while the work of wiring and attachment of the lamp supterior annular shoulder fitted over said stud,

a lamp socket support screwed upon said stud and clamping said shell in position, and a hollow metallic cylinder having a transverse annular rib formed thereon at a predetermined distance from its lower end, which end is fitted into the rim and rests upon said shoulder.

2. In a lighting fixture, the combination of a supporting arm provided on its free end with a'screw-threaded stud, a shallow shell having an angular concave rim and interior annular shoulder fitted over said stud, a lamp socket support screwed upon said stud and clamping said shell in position, a

hollow metallic cylinder having a transverse Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, I

of said shell upon the lower end of the cylinder and upon the rim of the shell for securing the cylinder against verticalmovement or accidental displacement.

3. In a lighting fixture, the combinationof a supporting arm'provided on its free end with a screw-threaded stud, a shell having an annular concave rim provided with a slot on two opposite sides, said shell havlng an opening in its bottom through which said stud is passed, a lamp socket support screwed upon said stud and clamping said shell in position, a hollow metallic cylinder having a transverse annular rib,'teats on opposite sides of said cylinder adjacent its lower end and adapted to enter the slots in the rim of said shell, whereby the said cylinder is held in position. i
