SPECIFICATION forming part of Letters Patent No. 294,697, dated March 4, 1884.

Application filed June 14, 1862.

of the city, county, and State of New York,

have invented a certain new and useful Improvement in Combined Gas andElectrie-Li ght Fixtures, of which the following is a specification.

The object I have in view is to produce a combined gas and electric-light fixture which will not be subject to the objection of forming a ground-connection when one of the conductors makes contact with some metal part of the fixture, and which will be simple, compact, and ornamental in construction, the conductors being all hidden from sight, and 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 tothe safety catch of the fixture, for the purpose of making repairs, testing the conductors or insulation, or removing the safety-catch.

In carrying out my invention the chandelier or bracket is constructed, as usual,with a supporting or sustaining stem or arm formed by a central gaspipe, which is secured to the pipe projecting from the ceiling or wall,and at its other end screws into a central distributingbody, from which project the arms carrying the gas-burners. These parts support ornamental shell-work, the stem being covered by a sleeve in one or more sections,while the distributing-body is covered bya ring, through which the distributing-arms pass, and by ornamental shells above and below this ring, the shell above the ring being supported by said ring, while that below it is supported by arod screwed into the distributing-body and projecting downwardly therefrom. A shell, cap, or canopyis used at the top or inner end of the fixture.

'To form my combined gas and electric-light fixture, the arms projecting from the distributing-body are divided between those intended for gas and those intended for electric light. Those for gas are of the usual construction, and receive the gas, as usual, .from the distributing body. The arms for the electric light are c l es epl gas tiglit at their inner ends; or the holes in the body into which they screw are not tapped all the way through the body;

(No model.)

ance they are like the gas-arms, do not connect with the interior oi the gas-body. Each of these electric-1i ght arms, outside of the gasbody, but within the ornamental inclosingbody, ring, or shell, has one or two openings made in it, out through which the two insulated conductors of the arm project into the space between the gas-body and the ornamental body. The main or stem wires of the fixture are passed into the sleeve covering thestem through one or more holes or slots made at the upper or inner end of said sleeve. These main wires are carried down through the sleeve, between the same and the central gaspipe, and enter the ornamental body.

In the space between the gas and ornamental bodies-of the fixture the stem and arm wires ing soldered, and then wound with insulatingtape. These connections are made before the lower part of the ornamental body is secured in position, and are inclosed within and co1npletely hidden by such ornamental body. The gas-arms are provided with gas-burnersas usual, while the electric light arms have sockets for incandescingelectric lamps, the wires within such arms terminating in the sockets without being exposed to view. The incandescing electric lamps are secured in such sockets, and may be arranged in an upright or in a reversed position. The gas and electriclight arms project from the same supporting body and in the same horizontal plane. Two or more of such supporting-bodies may be used in the same fixture, as is usual in gasfixtures, and each body may have gas and electric-light arms projecting therefrom; or one or more of such supporting-bodies may have gasarms alone, and one or more have electric light arms alone, the construction otherwise not differing, essentially, from that before described. At the upper or innerend of the fixture the main or stem wires are secured to the ceiling or wall wires. These latter wires are carried through the ceiling or wall near to the gas-pipe, or are led to the proper points upon the surface of such ceiling or wall. One ceiling or wall wire is connected with one of the main chandelier wires through an inclosed safety catch, the preferred construction of which is covered by an hence these arms, while in external appear- I application for patent already filed by me.

are connected together, such connections be- The connection of the other ceiling or wall wire and chandelier-wire is made by soldering the wires together and wrapping the joint thus 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, which is open on its side next to the ceiling or wall. This shell, cap, or can opy is made adj ust-able, to give ready access to the parts, it being secured to the sleeve covering the stem by one or more set-screws, by which it can be adjusted upon such sleeve. In this way, it will be seen, the adjustable canopy is secured to the fixture itself and not to the ceiling or wall, and itcan be located on such fixture at its upper or inner end at any distance from the ceiling or wall which the design of the fixture may require to secure the best artistic effect. The canopy can also be made of any suitable shape, size, or design without changing the devices for secur ing it adjustably upon the fixture, the canopy at its small. end being provided with a llange or collar which fits the fixture, and need only be made of certain definite sizes. The setscrcws for holding the canopy pass through this flange or collar. This matter not, however, herein claimed, except as applied to a combined fixture, the same being broadly covered by my Patent No. 259,235.

To prevent the accidental 'i'ormation ot' a grouiutconuection in the fixture, the gas-joint at the juncture of the fixturestem and the coiling or wall pipe is an electrical insulatingjoint. This joint is in the form of a gas union, with a ring of insulating material between the meeting i'aces ot' the union, and an insulating ring or cap under the flanged turning cap of the union. Hard rubber may be used for insulation, or any other material not injuriously affected by the gas.

To prevent the fixture from turning at the insulating-joint, the ring between the meeting faces of the union is provided with ribs or projections entering depressions in the parts of the union. This joint permits the gas to pass freely into the stem of the fixture, prevents leakage, insulates the entire fixture electrically from the ceiling or wall pipe, preventing the formation of a ground, allows the fixturc to be secured in position without turning it, and prevents the fixture lrom turning in use, which would cut the wires or abrade the insulating covering of the same.

The insulating-joint may be placed beyond the fixture, in the line of the ceiling or wall pipe; but an insulating-joint is required for each fixture, since the gas-pipe may be in contact with water or other pipes, or have other gronnd-connections at various points in the house, and hence the insulating- 'joint should be at or near the fixture to assure its effective ness.

The foregoing will be better understood by reference to the accompanying drawings, in which Figure 1 is a vertical section of a chandelier embodying theinvention; Fig. 2, a vertical section of a portion of a chandelier having two distribnting-bodies; Fig. 8, a sectional view illustrating the adjustable shell, cap, or canopy; and Fig. -l-, a sectional view of a slightlynnodified form of the insulating-joint.

Like letters denote eorrespoiuling parts in all the figures.

A is the gas-pipe, forming the central sup porting stem or arm oi. the fixture.

B is the central distrihating-body, having gas-arms C and electric-light arms 1) projecting thereirom, the latter arms not passing into the interior of the body 13, as shown at (I.

ll is the ornamental sleeve covering the stem A, and F is the ornamental shell-body covering 13. This ornamental. shell-body may be composed of a ring, I, through which the arms 0 D pass, a shell, 0, resting upon such ring and completing the upper side of the shellbody, and a shell, (I, closing the lower side oi the ornamental sheltbod y, and supported by a rod, 0, pendcntl'rom the distributing-bodyl3.

Instead of having one distributing-body l3 and covering ornanientatiou, the fixtures may be provided with two or more of such bodies placed one above the other. The use of two of such bodies is illustrated in Fig. 2.

(iis the canopy, which is secured by one or more set-screws, to the ornamental sleeve l), and is adjustable vertically thereon. These screws pass through a tlange or collar, f, upon the small end of the canopy. This flange or collar has to be made of certain definite sizes to fit the several. sizes of fixture-stems or ornamental sleeves; but the canopy itself can be made of any shape, size, or design, and can be located at the inner or upper end of the fixture, at any distance from the ceiling or wall which may be required by the design of the fixture. llach gasarm has any suitable gas-burner, mounted thereon.

H is the incaiu'iescing electric lamp, secured in a socket, 71, attached to the end ot each arm 1). This electric lamp may be in a reversed or upright position. The insulated arm-wires 1 2 terminate in this socket, and are hidden from sight; within the arm. They pass out 01' the arm into the space between the distributing-body and the ornamental shell-body through one or more openings, '1', in the arm. The main chandelier-wires 3 -.t pass from the canopy G, through one or more holes or slots, into the interior of the sleeve 1* and down through such sleeve to the lower end of the same, and then out of the sleeve into the orna' mental. shell-body F, where they are secured to the arnrwires, as shown. The ceiling or wall wires 5 6 are secured to the main chaudelier-wires b -.t within the canopy (i, one connection being through the incloscd safetycatch 7:.

I is the ceiling or wall gas-pipe, which is socured to the pipe A of the fixture by the in sulatingjoint K. This joint is a gasunion composed of a screw-collar, secured to A, a plain collar, ml, 01. smaller size than Z, secured to I, and a llanged cap, n, screwing onto Z and drawing m by its flange. A ring, 0, of g hard rubber or other proper insulating material, is placed between the opposing faces of l and m, while an insulating-cap, p, is placed under it and between it and m.

The cap p may be replaced by a simple ring,

p, Fig. 4, placed under the flange of n and projecting beyond the edge of on, while the ring may also project beyond an, the two rings effecting a complete insulation of the parts of the joint.

To prevent the turning of the fixture at this joint and the cutting of the wires, the insulating-ring 0 has projecting points or ribs entering corresponding depressions in the faces of Z and m, as shown.
