- To all whom it may concern.-

Be it known that I, LUTHElt STIER IXGER, of the city, county,and State of New York, have'invented a certain new and useful Im-' provement ina Combined Gas and Electric- Light'bixtu re,oi which the iollowin gis especification. v

The object I have in view is to produce a combined gas and electric-light fixture constructed wholly or largely of metal and provided with insulated conducting-wires for conveying the electric current to and from the electric lamp or lamps Supported thereby, which fixtu re will not be subject to the objection of forminga ground connection when one of the conductors makes contact .with some n iota-i part of the fixture,and' which will be simple, compact, and ornamental in construction 1 the conductors being all hidden from sight and 36- supporting or sustaining stem or arm formed the fixture presenting the appearance of a complete integral fixture, and which, further, while hiding the conductors and-connections, will give ready-access to such connections-and to the safety-catch? of the fixture for the purpose of making-repairs, testing the conductlors or insulation, or removing the safetycatc 1.

' In carrying out my invention the chandeby aceutral gas-pipe, which is secured to the pipe projecting from the ceiling or wall, and

at its other end screws intoa central distrib-, uting-body, from which project the arms earrying the gas-burners. flhese pants support ornamental shellwo'rk, the stem being covered bya sleeve in one or more sections,while the distributing-body is covered by a ring through which thedistrib uting-arms pass and by ornam ental shells above andbelow this ring, the

shell'ubove the ring being supported by said ring, while that below it is supported by a rod screwed into the distributing-body and projecting downwardly therefrom. A shell, cap, or canopy isused at the top or inner end of the fixture. v

To form my combined gas and electric-light fixture,the arms projecting from the distributing-bodyare divided between those intended for gesiaud those intended for electriclight. '1l ose for gas are of the usual construction,

I and receive the gas, as usual, from the distributzn'g-bod y. The arms for the .eleetricfore described.

wall near to the gas-pipe, or

light are closed gas-tight at their inner ends, or the holes in the body into which they screw are not tapped all the way through the body.-

Hence these arms, while in external appear ance they are like the gas-arms, do not connect with the interior of the gas-body. of these electric-light arms outside of the gasbody, but within the ornamental inclosing' body, ring, or shell, has one .or two openings made in it, out through which the two insulated conductors of the armproject into the space between the gas-bod y and the ornamental body. The main or stem wires of the fixture are passed into the sleeve covering the stem through one or more holes or slots made Each at the upper or inner end of said sleeve.

These main wires are carried down through the sleeve, between-the same and the central gas-pipe, and enter the ornamental body.-

In the space between the gas and ornamental bodies of the fixture the stem and arm wires are connected together, such connections being soldered and then wound with in-'.

sulating-tape. These connections are made before the lower part of the-ornamental body is secured in position and are iuclosed within and completely hidden by such ornamental body; The gas-arms are provided with gasburners, as usual,while the electric-light arms have sockets for ineandescmg electric lamps,

the Wires within such arms terminating in the sockets without hein g exposed to. view. The

such sockets and may be arranged in an upright or in a-reversedposition The gas end 7 electric-light'arms project from the same supportin g-bod y and in the same horizontal plane. Two. or more of such supporting-bodies may be used in'the san1e.fixture,,as is usual in gas-- fixtures, and each body may have gas and electric-light arms projecting therefrom,or

one or more of such supporting-bodies may have gas-arms alone and one orunore have electric-lightnrnis alone the con struetion otlierwise not differing, essentially, from'th'at be- Atthe upper or :inner end of the fixture the main or stem wires aresecured to the ceiling or wall wires These latter wires-are carried through the ceiling or are led to the proper points upon the surface of such ceiling or wall. One ceiling or wall wire is connected with once! the main chandelier-wires through lbs 85 incandescing electric lamps are. secured'in an inclosed safety-catch, the preferred construction of which is covered by an application for patent already filed by me. ,The connection of the other ceiling or wall wire and chandelier-wire is made by soldering thewires together and-wrapping the jointthus made. These connections, including the safety-catch and the joint at the upper or inner end of the fixture, are hidden by a shell, cap, or canopy, IO

or wall. This shell, cap, or canopy ismadc T adjustable to give ready access tothe parts,

" it being secured to the sleeve covering the stem by one or more set-screws, by which it can be adjusted uponsuch sleeve. In this way, it will be seen, theadjustable canopy is secured to the fixture itself and not to the ceiling or wall, and it caube located on such fix-' V ture at its upper or inner end at any distance from the ceiling or wall which the design of the fixture may require tosecurethe best artistic effect. The'canopy can also bemade of any suitable shape, size, or design without chang:

ing' the devices for securing-it adj us'tably upon the fixture, the canopyfat its small end being provided; with .a flan'gefor collar which fits the fixture and need only be made of certain definite sizes. 1 The set-screws-for holding the canopy pass through this; flange or collar. This matter is. not, however, herein claimed, except as applied to a combined fixture,ithe same being broadly coveredgbym'y Patent No. .259,235.' 7 sf i 1 .1 To preventthea'ccidon'tal vformation of a ground connection in the fixture, the gas-joint at the juncture of the fixture-stem and the ceil ,ing or wall pipe is an electrical insulating This jointis inthelform of a, gas-- .io t union, with a ring of inulating' material between the meeting facesof the union and an insulating ring or cap under-the flanged turn-' ing cap of the union. I rubber maybe usedii'o'r insulation, orany other" material not injuriouslylatfected by the 7 '7 5 To preventthe fixture fipmturning-atthe insulati glgz' joio t, the ringbetween the meeting faces not n oii isipjo'vided with rihs'or projecti the parts of tact with'water or other pipes, or have other,

- ground connections 'at-v'ariouspoints in the house, and hence the insulating-joint should-- 5 be at or near the fixture to assure its'ellective ness.

The foregoing will bebetterunderstood by,

which-is open'on its side next to the ceilingis adjustable vertically thereon. screws pass through a flange or collar f upon This flange orz'jointpe'tmits the gas to pass which Figure 1 is a vertical section of a chandelier embodying' the invention; Fig. 2, a vertical portion ofa-chandclicr having.

Bis-the central distributing-body, having gas-arms C and electric-light arms D projectingtherefro'm, the latter arms not passing into the interior of-the body B, as shown at a.

E is the ornamental sleeve covering the stem A, and F is the ornamental shell-body sup.

covering 13', This ornamental shell-body may be composed of a ring 11, through which the arms 0 D pass, a shell 0, resting upon such ring and completing the upper side ofthc ishelhbody, and a shell (1, closing thclower side. of the ornamental shell-body and sup: ported by a rod Ming-body B.

be provided with two or more'of such bodies Instead of having one distributingbody B and covering ornamentation, the fixtures may e, pendent frontthc'distrihplaced one above'the other.. The use of two i a of such bodies is illustrated in Fig. 2.. G is the canopy,which is secured-byone or' more'set-screws f to the ornamental sleeve E,

the small end of the canopy. I dollar has to be made of certain definite sizes to lit the several sizes of fixture-stems or ornainental sleeves; but the canopy itself can be made of'any'shape, size, or design, and can beilocated'at :the inner or upper end of the fixture, at anydistance from the ceiling or the fixture. I Each gas-arm has any suit-able gas-burner g mounted thereon,

. II is the incandescing electric-lamp,- secured in a socket 7!, attached to the end of each arm D. This electric lamp may be in a reversed These 1 .wall which may be required by the design of oru'prightposition. Theinsulatedarm-wircs a 1 -2 te rminate in this socket, and are hidden" from sight within the am. They pass out of the into the space between the distributing -body and the ornamental shell-body through one or more'openings i in the arm. The main chandelier-wires 3 4 pass from the -cauop .G, throughone or more holes or slots,

into .1. e, interior of the sleeve E, and down through such sleeve to the lower end of the same, and then out of the sleeve into the ornai mental shell-body F, where they are secured to the arm wir'es, as shown. "The ceiling or wall wires 5 6 are securedto the main chandelier-wires 3 4 within the canopy G, one con-- nectionbeing through the inc catch k. a

osed safetv- I isthe ceiling or wall gas pipe, whichis secured'to the pipe A of the fixture by the insulating-joint K. This joint is a gas-union composed of a screw-collar l, secured to A, a plain collar m, of smaller size than i, secured to I, and a flanged cap 11, screwing onto Z and drawing m by its flange. A ring 0, of hard rubber or other proper insulating material, is placed between the opposing faces of Z and iii, while an insulating-cap p is placed under n and between itand m. r

, The cap 1) maybe replaced'by a simple ring 1), Fig. 4, placed under the-flange of n and projecting beyond the edge of m, while the ring 0 may also project beyond m, the two ringsefi'ectinga complete insulation of th parts of the joint.

To prevent the turning of the fixture at this joint and the cutting of the wires, the insulat ing-rin g 0 has projecting points or ribs entering corresponding depressions in the faces of Z and on, as shown.
