CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 626,907, dated June 13, 1899.

Application filed January 7, 1898.

To coll whom t may concern:

Be it known that I, HENRY JAMES Hnwrrr, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chandeliers, of which the following is a full, clear, and exact specification.

My invention relates to chandeliers or lightsupports, and the improvements have more especial reference to means whereby the altitude of the light may be varied to suit the requirements of the'user, thus enabling the user to draw the light down close to a table, for instance, or to elevate it out of the way, as desired.

The object of my invention isto provide an improved construction of extensible chandelier or light-support which will enable the end thereof supporting the light to be readily raised or lowered and locked at the desired elevation. 4

Another obj ect of my invention is to so construct the parts of an extensible chandelier or light-support that the lower or movable part will not fall or descend violently in the event it should be accidentally released.

A further object of myinventibn is to provide means for locking the telescoping parts of the gas-chandelier which shall also constitute a packing for preventing the escape of gas between the telescoped members.

lVith these ends in view myinvention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a side elevation of my improved chandelier, showing it adapted for using gas. Fig. 2 is an enlarged vertical sectional view, partly broken away, the globe being omitted. Fig. 3 is a transverse sectional view taken on the line 3 3, Fig. 2; and Fig. 4 is a view similar to Fig. 2,

partly in section and partly in full, showing y the construction of one'of the internal tubes,

the view being 1 represents the gas-pipe, cured at the ceiling to the threaded the ordinary service-pipe taken at right angles to Fig. 2.

which may be seend of (not shown) or atserai No. 665,889. (No maar.)

tached in any other suitable way to the gassupply, and 2 represents a casing in which the pipe 1 is inserted and to the lower end of which is secured the chandelier 3 or the parts for supporting and supplying the burner or burners 4f. The lower end of the pipe 1 is screw-threaded upon or otherwise attached to a sleeve or collar 5, and passing upwardly through this sleeve or collar is a tube 6, provided from top to bottom with a spiral groove or channel 7, in which engages one or more studs 8, secured to the inner side of the sleeve 5, such studs S, if desired, being in the form of Small rollers or antifriction-wheels of less diameter than the width of the groove 7, so as to roll therein as the tube 6 is pushed up or pulled down, and thus relieve the wear upon the studs. I have shown and prefer to employ two of these studs 8 on opposite sides and atopposite ends of the sleeve 5, so as to provide a more uniform bearing.

The lower end of the tube 6 is reduced in diameter, as clearly shown in Fig. 2, and carried downwardly through and swiveled in a collar 9, which latter is secured to the lower end of the casing 2 by means of pins or screws 10 or in any other suitable way, and the extreme lower end of the reduced portion of the tube 6 is threaded and has secured thereon a' nut 11, which takes its bearing under the collar 9, and thus swivels the tube (5 to the casing 2 in such a manner that the tube 6 and casing 2 will be compelled to rise and fall together and at the same time allow the tube to revolve independently of the casing 2. desired, a leather or othervwasher 12 may be interposed between the nut 11 and the lower end of the collar 9 to relieve the parts of wear.

The portions 3 of the chandelier are provided with a hollow head 13, from which lead the pipes for supplying the burners with gas, and the upper end of this head 13 is screwthreaded upon or otherwise attached to the lower' end of the collar 9, the head 13 being 'of larger diameter than the nut 11, so as to permit the latter to turn. The screw 10 also serves as means for binding the head 13 and casing 2 together.

The upper end of the tube 6 is provided with a flange 14, which makes suchend of the tube lof sufficient diameter to fit accurately within the pipe 1, with capability of sliding, and supported upon this flange 14 is a combined lock Ifr IOO

and packing consisting of a normally-cony tracted ring 15, which is divided and has its divided ends overlapped in the manner of an ordinary steam.- packing, as more clearly shown in Fig. 4. WV hen this ring is in its normal condition, it exerts no material pressiire against the walls of the pipe 1, but when expanded with sufficient force it binds against the walls and forms a solid support for the tube 6, the casing 2, and other parts of the chandelier supported thereon. In order that the ring 15 maybe'thus expanded when it is desired to lock the tube 6 within the pipe 1, I arrange at the upper side thereof a tooth or wedge 1(3,which has operative connection with an interior rod 17, connected at itslower end to an exterior operating lever or handle 18,

. the latter being secured to a transverse conical shaft 19, journaled in the head 13 and having eccentric or crank connect-ion 2O with the rod 17. The tooth 1G is arranged within or directly over a notch or pair of inclines 21, formed in the upper edge of the ring l5, and when such tooth is pulled downwardly into engagement with these inclines it forces the ends of the ring in opposite directions and causes the ring to expand within the pipe 1, thus. at once locking and supporting the tube and preventing the escape of gas from the pipe 1 into the space between the latter and the tube 6, and thereby avoiding the possi- 7 and thence to the atmosphere through the space between the pipel and casing 2. The ring 15, it will be4 seen, is provided with alapjoint 1G, like a piston packing-ring, which has overlapping portions when viewed from the side, as in Fig. 4, and also overlapping portions when viewed in cross-section, as in Fig. 2.

In order that the tooth 16 maybe held and guided, the upper end ot' the tube 6 is provided with a reduced neck 22, and the tooth 1G is formed on a ring 23, surrounding such neck and having a collar 24, attached by spider 25.and nuts 26 to the upper end of the rod 17, thus supporting the rod upon the collar 15 when the latter is expanded and at the same time aiordin g a free passage-way for-the gas down through the tube G.

It is, of course, very evident that where electricity isl usedl for light the wires may be extended through the pipe 1 and other gaspassages of the chandelier without departing c from the spirit of my invention.

IVith an extensible chandelier thus constructed it will be seen that when the operating-lever 18 is turnedI in one direction the tooth 1G will be elevated out of engagement with the notch or inclines 2l, and in thus allowing the ring 15 to contract the chandelier may 'be raised or lowered, as desired, and when the proper elevation is reached a turn ofthe lever 18 in the opposite direction will again expand the collar 15 and lock the parts.

together, as described. Should the lock be accidentally released, the chandelier would descend of its own weight; but the spiral groove 7 and studs S would afford sufcient friction to prevent damaging shock, the upper one of the studs 8 serving, when the end of the groove 7 is reached, as a stop for preventing further downward movement.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. An extensible chandelier havingin combination a fixed pipe, a hollow head to which the globe or light of the chandelier is attached, a tube swiveled in and supporting said head, said tube and pipe being provided with spiralgroove and stud connection,means for locking said tube and pipe together, and.
