SPECIFICATION forming part of Letters Patent No. 258,106, dated May 1e, 1882.

Application filed December 27, 1881. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN S. NEWTON,

` a citizen of the United States of America, re-

siding at Binghamton, in the county ofBroome and State of New York, have invented certain new and useful Improvements in Chandeliers and I do hereby declare the following to be a full, clear, and exact description of the iuven` tion, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or gures of reference marked thereon, which form apart of this specification.

Figure 1 is a vertical section oi" a chandelier embodying my improvements. Fig. 2 is a perspective ot' the piece which supports the chandelier upon the swivel. Fig. 3 is avie'w ofthe guiding-plate at the top ofthe sliding tube detached. Fig. et is an edge view of the springdrum frame and the sliding plate which oper-u ates the detent. Fig. 5 is a longitudinal section of a somewhat modified construction of chandelier. Fig. 6 is an edge'view of the frame l'or the spring-drum. shown in Fig. 5.

In the'drawings, Arepresents an upper tubesection, and B a shell or bulb above the tube. These parts are held in contact with a supporting-piece, C, by means of a rod, D, and a "bottom cap-piece, E. The rod D has an eye,

d, below the cap-piece E, andis provided above the part C of the supporting-piece O with a` nut. By means of this nut the cap can be drawn up tightly,`so as to clamp the tubeA and bulb or shell B against the part C.

c is a swiveling-eye for supporting the chandelier upon a ceiling-hook. v

F represents the outer sliding tube-section. Itis held in proper position relatively to the inner section by means of a guiding-plate, F', at the upper end, having a square aperture, through which passes the upper tube-section, A, the latter being square in cross-section to t said aperture. The cap at the bottom of tube-section A has an annulus, c, for properly spacing the tubes at the bottom. The sliding tube-section F supports a frame, Gr, for carrying a cord or chain winding mechanism. The frame has armsg g at the upper end, carrying a screw-threaded collar, g', engaging with a thread in the lower part ot' tube F. In the frame Gr is mounted a shaft, H, and drum H', with a coiled spring, IL, arranged to rotate the drum. p

I is a cord, having one end attached to the drum and the other to the eye d on rod D. The drum is provided with flanged ends having teeth i. With these teeth engage one or more-detects at i. These detents are carried by a cross-bar, J, which is connected to a yoke or U-shaped frame, K.

L is the shell or bulb, which conceals'the cord-winding mechanism, and also supports the bracketed arms L' for the lamps. This shell is held in position by the frame G, the shoulders g2 of which crowd the part l of the shell upward around the sliding tube F.

Misathumbpiece attached to the yoke or U- .frame K, aud projecting downwardlythrough the bottom of the bulb L, said bulb having prefera-bly a lower supplemental part, L2, through which also the thumb-piece M passes.

m is a spring connected to the thumb-piece M inrsuch manner that it tends to force said thumb-piece downward. This downward forcing of the part M and the yoke K holds the detents z" in engagement with the toothed dan ges i of the drum H.

N is a guiding-pulley for guiding the cord properly from thedrum to the eye d. l

When it is desired to unlock the chandelier thethumbis pressed upwardagainstthethumbpiece M, (it being providedV preferably with a ball, O, to receive the pressure of the linger,) which upward pressure disen gages the detents i from the toothed or ratcheted flanges i. After this the chandelier and the sliding tube F can be carried down to any desired position, and there locked b v withdrawing the thumb from the part M and allowing the detents i' to again engage with the teeth i.

It will be seen that all the weight of the chandelier is supported in such manner as to relieve the tubes A and F entirely of strain, the cord or chain I, rod D, and part O transferring all of said strain to the hook or other fixed object in the ceiling.

Instead of supporting the drum-frame in the manner shown in Fig. l, it may be attached to a cross-bar, P, fastened rigidly across the interior of the shell L, as shown in Fig. 5. Insteadof havin gthe yoke or U-frameKarran ged IOC to run up by the sides or edges of the drumfrarne, -it may be placed against the face of it, as shown in said figure.

The spring m may be placed between the bottom of the drumframe G and the bottom of the yoke K, so as to tend to thrust the latter downward, as shown in the last said ligure. When the spring is thus arranged there should be pins 7c 7c to hold it in proper position. This figure shows also another method of supporting the chandelier upon the upper part, G. The cordIfrom the drum H extends up through the stationary tube A, and is fastened by an eye at c2 to the part D, which in this case is a short extension of the part C, as is shown in full lines, though it may be fastened to a crosspin at C2 in the tube A, as shown in dotted lines. This latter means of supportthat is, at (l2-is not so desirable as the other, as it imparts to the upper tube, A, the strain incident to supporting the weight of the chandelier and the other tube, F.

The part O may be fastened to the other tube-section, A, by screw-threading thepart D and engaging it with a disk or plate, A', in

`the upper end` of the tube A, the plate and shank being secured to the tubebyasetserew,a. Instead of the devices above described for preventing the rotation of the tubes relative to each other, use may be made'of a slot or groove in one and a set-screw or feather in the other corresponding` to the slot or groove.

What I claim is- 1. The combination of the stationary tubesection, the sliding tube-section, the ratcheted spring-drum in the sliding tube-section, the frame Gr for supporting the drum, the thumbpieceVY projecting through the bottom of the sliding section, the cross-bar J, having detents to engage with the ratcheted drum, the U- shaped or forked yoke K, carrying said crossbar J, and guides secured to the drumframe to support'the U-shaped yoke, substantially as set forth. Y

2. The combination of the upper stationary tube-section, the lower slidingtubesection, the cord connected at one end to the upper tube-section, the cord winding mechanism supported in the lower tube-section, the fra-me G, the yoke K, carrying detent t', and the ratchet-teeth carried by the drum, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

STEPHEN S. NEWTON.
