ELECTRIC AND COMBINED ELECTRIC AND GAS CHANDELIER OR BRACKET.

I SPECIFICATION forming part of Letters Patent No. 621,104, dated March 14, 1899.

Application filed June 6,1898. Serial No. 682,655. (No model.)

To aZZ whom it may concern.-

Be it known that I, WVILLY H. LAU, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Electric and Combined Electric and Gas Chandelier or Bracket, of which the following is a specification.

My invention relates to improvements in electric and combined electric and gas chandeliers and brackets; and the object of my invention is to obtain an electric and also a combined electric and gas chandelier and bracket in which the ordinary insulatingjoint heretofore used in such chandeliers and brackets will not be required for the gas-pipe, but in place thereof a loop (forming a cap and joint to the gas-pipe) or a common stifi joint will be used to obtain a combined electric and gas chandelier or bracket which can be used without causing combustion from the electric conductor or fixture used in connection therewith, and to obtain an electric and a combined electric and gas chandelier and bracket in the use of which no grounding of the electric conductors will be liable to occur.

A further object of the invention is to obtain an electric and a combined electric and gas chandelier and bracket which will be sightly in appearance, readily assembled, and durable.

In the drawings accompanying and forming a part hereof the manner in which the objects sought is well shown in the mechanisms illustrated, in which drawings- Figure 1 is a sectional elevation of a com bined electric and gas chandelier embodying the invention; Fig. 2, a bottom plan view of the chandelier illustrated in Fig. 1; Fig. 3, a bottom plan view of a modification of a portion of the chandelier illustrated in Figs. 1 and 2, showing a chandelier arranged for electric connections only. Fig. 4 is a detail view of the combined gas and electric distributer, forming an element in the apparatus embodying the invention. Fig. 5 is a plan View of the combined electric and gas distributer illustrated in detail in Fig. 4, and Fig. 6 is a sectional elevation of a stiff-joint cap for an electric chandelier or bracket.

A reference-letter applied to designate a given part is used to indicate such part throughout the several figures of the drawings wherever the same appears.

A is a stiff joint in common use in gas-fittings.

B is an ordinary vertical gas-pipe for a chandelier'secured in stiff joint A by means of external screw-threads thereon, fitting corresponding internal screw-threads in stiff joint A.

C is an ordinary gas-distributer.

D is an ordinary casing in common use in gas-pipe fittings.

E is an ordinary canopy.

F is a sleeve on pipe B, of non-electric conducting material, forming an insulatingsleeve interposed between the casing D and stiff joint A.

G is a pipe of non-electric conducting ma terial forming an insulating-covering to the gas-pipe B.

H is an electric distributer comprising the central body part it of non-electric conduct ing material, and the metal rings 71. h, secured together and to the part h by the bolts h 72 having nuts k 71 respectively, thereon. Body part h of electric distributer H may be composed of two pieces h h, as illustrated in Fig. 4. The upper ring It has lugs or projections 71 h on the peripheral edge thereof, and the lower ring h has short projections 716 h on the peripheral edge thereof, arranged to engage with projections k W, respectively.

I I are holes through the central body part 71. of non-electric conducting material,through which the ordinary gas-pipes J J extend to connect with the gas-distributer C in the ordinary way, as by external screw-threads on the gas-pipe engaging with corresponding in-' ternal screw-threads in the hole in the gasdistributer. The gas-pipes J J thus serve to hold the electric distributer H in place surrounding the gas-distributer 0.. When no gas-pipes J J extend through the electric distributer H, or an insufficient number to hold it in place extend therethrough, bolts or screws J J, as in Fig. 3, are used to secure such electric distributer to the gas-distributer. When the part h of electric distributer H is made in two parts, as h h, Fig. 4, the hole I is obtained by having the grooves i 2' made in the respective parts k h.

K is a sleeve of non-electric conducting material on gas-pipe J. The hole I at the end thereof adjacent to the periphery of the electric distributer H is made of the same diameter as is the sleeve K, and such sleeve K enters into such hole I to avoid the necessity of close fittings in assembling the several parts of the apparatus.

L is a metal band having holes Z Z Z therein, through which holes the sleeves K K pass, respectively, thereby insulating such band, as well as supporting it in place.

M is the upper half of a globe, which rests on its lower peripheral edge on hand L.

N N are internally-screw-threaded holes in projections 71,5 7L5, respectively, into which holes the hollow electric arms or brackets O 0 respectively fit, and by which such brackets or arms are supported. Arms or brackets O 0 have external screw-threads O O thereon, fitting internal screw-threads N N.

P P are holes or grooves through electric body part h of electric distributer H, through which holes the electric conductors Q pass to enter the arms or brackets O 0, respectively. Vhen part it of the electric distributer H is made of two pieces, as h h, Fig. 4:, the holes or grooves P P are obtained by making the grooves 19 p in such parts h 7t.

Toinsert electric conductor Q in place, hole or slot q having been provided therefor, such conductor is placed within the casingD at the upper end of such casing and covered by the canopy E and extended downward through the casing between it and the insulating tube or material G to underneath the combined electric and gas distributer H C. From thence the conductor Q is put through holes P P into the arms or brackets O O and to the electric lamps O O in the ordinary way.

R is a bracket, which may be of metal, secured to the electric distributer H by the bolts 7&2 7L2, and S is a bolt extending through bracket Rand secured in an adjusted position therein, as by external screw-threads S S thereon, fittinginto corresponding internal screw-threads R R in bracket R.

M is the lower half of a globe surrounding the combined electric and gas distributerI-I O, and is held in place against band L by bolt S. Access can be obtained to electric conductor Q at any time by removing bolt S and lower half M of the globe.

WVhere an electric chandelier or bracket only is to be secured to and held in place by a gas-pipe, the gas-pipe can be closed and the chandelier. or bracket suspended from the loop T, forming a combined cap and joint. (Illustratedin Fig. 6.) Loop T comprises the internally screw-threaded part i, fitting over the gas-pipe in the same manner as stiff joint A is fitted thereover, and secured thereto by the internal screw-threads therein engaging with external screw-threads on the gas-pipe, the plate t closing the openingin the gas-pipe, and screw-threaded part to which the pipe U is secured, as to a stiff joint, by external screw-threads u thereon engaging with corresponding internal screw-threads i 25 and the hollow body part having hole V therein below plate 2, through which hole the electric conductor is inserted to extend through pipe U.

\V is apipe ortube of non-electric conducting material inserted in pipe U to insulate the conductor Q from such pipe.

Y is a plug in gas-distributer C.

The combined electric and gas distributer H O can be secured to thelower end of the pipe U, Fig. 6, (which may be ordinary gaspipe,) in the same manner in which such combined electric and gas distributer is secured to thelower end'of pipe B -that is, by having external screw-threads thereon fitting into corresponding internal screw-threads in a hole in such combined electric and gas distributer. In such case the electric arms or brackets O 0 may be of the same size as hereinbefore described and secured in place to the combined electric and gas distributer II C, as described, and the screws J J, Fig. 3, be substituted for the gas brackets or arms J J, Fig. 2. The conductor Q will then pass entirely through the pipe Uand the combined electric and gas distributer H 0, coming out of such combined electric and gas distributer at the bottom thereof,and from thence through holes P P and into the electric brackets or arms 0 O, as hereinbefore described.

It will be evident that by having a hole on the under side of the combined electric and gas distributer II C an additional pipe 13 or an additonal pipe U can be suspended to the combined electric and gas distributer, and so more than one series of gas and electric arms or brackets (or electric arms only) obtained. Where pipe U is to be suspended to the combined electric and gas distributer, an additional stiff joint A and joint T is interposed between the combined electric and gas distributer and such pipe U.

X X are insulating-rings to canopy E.

To assemble the several parts embodying this invention, the pipe B is secured to stiff joint A, insulating tube or pipe G is placed over pipe B, insulating ring or sleeve F is put in place, casing I) is placed over the pipe B and tube G, insulatingr ing X, canopy E, and insulating-ring X placed over the casing D to be slid up into place after the conductor Q has been inserted through slot or hole (1 and brought down through the casing D and the upper half of globe M M put in position. The combined electric and gas distributer H O (to which the gas arms or brackets J J electric arms or brackets O O, and band L may have been previously attached) is secured in place at the lower end of the pipe B and the conductor Q electrically connected (through the holes P P and arms or brackets O O) with the electric lamps. The lower half of the globe M M is then put in place and secured by the bolt S.

Before putting the lower half of globe M M in place the lower hole through the combined electric and gas distributer H O is and bracket,the combination with an ordinary vertical pipe, gas-distributer and gas-bracket arms, of an electric distributer concentric with the gas-distributer and comprising a ring of non-electric conducting material surrounding the gas-distributer, through which ring the gas-bracket arms extend thereby supporting it in place, electric bracket-arms secured in the electric distributer, a band supporting the upper half of the ordinary ornamental shell, such band concentric with the gas-distributer and having holes therein through which the gas and electric bracket arms extend, whereby such bandis supported by such arms, with non-electric conducting material interposed between the gas-arms and the band,-and means for removably attaching the lower half of the ordinary ornamental shell to the electric distributer; substantially as described.
