SPECIFICATION forming part of Letters Patent N o. 258,104, dated May 16, 1882.

l Application tiled December 27,1881. (No model.) u y ing drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure lis a vertical section of a chandelier embodying my improvements. Fig. 2 is a cross-section `on the line x of Fig. 1. t Fig. 3 shows a modification of the devices for withdrawing the catch-lugs. Fig. t is a section of 4line y y `ot Fig. 4. i Fig. 6 illustrates another modied form embodying the lockingdugs shown in Fig. 4.

In the drawings, A is an upper stationary tube, with a bulb, A', at the top.

a is a bracket-frame with legs attached to or formed with athreaded ring, a', screwed into the tube-section A. This bracket-frame a carries a spring-drum, a2, preferably having the spring concealed within it. a3 is a chain or cord secured to the spring-drum at oneend. a,4 is a swivel-eye for attaching the chandelier to the ceiling or other fixed point'.

At the lower end ot' the stationary tube A is a stationary stopping device. In the coustruction showu in Figs. land 3 this stationary stop consists of a round plate with a central squareapertnre. (See Fig. 2.) In the construction shown in Fig. 4 this stop Bis a rectilinear plate with an elongated or oblong aperture. (See Fig. 5.) By placing this stationary stop at the bottom of tube-section A the chandelier is permitted to move downward the full length of tube A. With this stationary stop engage movable stops, carried by sliding tube-section G. This tube-section carries the bulb D, which supports the bracket-arms for the lamps D.

The stops which movewith the tube-section G and bulb D are represen ted by e. They may be moved into such position as to engage with the stationary stop B, either by thrusting them outward, as in the construction shown iu Figs. l and 3, or by rotating them, as in Figs. l.tand 6. In the construction shown in Fig.` l they are thrust outward by means of wedges orinclined surfaces, preferably arranged as in the said gure-that is to say, said stops c are formedu upon a bar, E, the face of which, opposite to the stop-lugs, is formed with a series ot inclined or wedge-like facets. These engage with corresponding wedge-like facets formed upon an opposing bar, C. This opposing bar C forms the one side of a square tube, G2, adapted to slide throughthe central square aperture in the stationary tube A and stop B, the sliding bar E, which carries the Astop-lugs c', being situated within this square tube. Upon one side of the square tube there is a slot, c', through which can .pass the st0plugs c.

Tube C2 isconnected to thebulb and the sliding tube-section C by means ot' cross-bar F, rigidly secured in position within the bulb, to which bar the tube C2 is attached. The

cord or chain a3 is fastened to the upper end of the tube C2.

The bar E, lwhich carries the stop-.lugs c', can be moved by the operators hand by means of a rod or link, E', connected to bar E at the upper end and at the lower end connected to a thumblink, E?. This last said link passes through the bottom of the bulb D, and is connected with a spring, E3, which tends to thrust thelink downward. It will now be seen that it' a spring be used at c2, whose tendency is to constantly draw the chandelier upward, the wedge-faces d in the tube G2 will crowd against the wedgefaces f of bar E and throw said bar outward, so that the stop-lugs c( shall bear against the stationary stop B and prevent any upward movement ofthe chandelier. When it is desired t0 unlock the parts the operator pulls down slightly upon the chandelier by means ofthe lower bulb or shell, E4, and at the same time pushes upward against the thumb-piece E2. This latter action tends to force the bar E back toward the center, as there are one or more inclined faces or shouldered', in the upper end of tube C2, so arranged that they will IOO ' throw the bar E inward into tube G2 when said bar receives upward pressure. If, on the other hand, the weight of the chandelier be greater than the power of the spring at a2, then the spring E3 will tend to slide the lugs e outward, so that one or the other of them shall rest on the top of the stop-piece B, and thus they can be made to lock the chandelier in any position. If desired, thetop of the stop B and the bottom of each lug may be beveled, as shown atf.

Instead ofthe wedge-faces el in tube G2 and wedge-faces f on bar E and the return-wedges d', use may be made of a link-connection, such as shown at d2 in Fig. 3. This connection may be formed by links at the sides ofthe sliding parts, or, preferably, by means of sockets cast v inthem and detachable links with enlarged 'E outward, as described above.

'E2 said links tend to throw the part E inward again toward the part C2.

The stop-lugs e', instead of being made to slide out and in, engage with and be disengaged from the stationary stop B, may be made to rotate around the center, devices adapted to perform this operation being shown in Figs. 4t and 6. In this construction the cord or chain a3 is connected by a swivel-connection, a4, with a central bar or rod, which is lettered C2, as it operates to support the weight ot' the bulb D andthe sliding tube-section C (being between the chain or cord a3 and the cross-bar F) in a manner similar to that of the operation of the part lettered C2 in the construction shown in Fig. 1. The stop-lugs e are attached to this central bar, O2, they preferably, in this case, projecting from the bar on two opposite sides.

rIhe central part, G2, passes through the stationary stop B, which is provided with an oblong aperture, G, through which the stop-lugs e can pass when the bar is turnedinto one position. When the bar is turned into any other position the lugs above the stop B prevent the chandelier from moving downward, and the lugs below the said stop B prevent an upward movement. rlhe bar may be rotated by any preferred devices for the purpose of causing the lugs' e to coincide vertically with the aperture' G, and vice versa.

In thedrawings the rotating mechanism consists of two small bevel wheels or sectors, one, H, attached to the bar C2, and the other, H', mounted (preferably loosely) on cross-bar F and a link, I, connected to the thumb-piece E2. If the thumb-piece be thrust upward, the wheels or sectors H and H will rotate the bar C2 sufficiently far to bring the lugs c e in the same plane as the aperture Gr, whereupon the chandelier can be moved up or down to any desired point. NVhen at such point the thumbpiece E2 is released and the bar C2, through wheels H and H', link I, and thumb-piece E2, is turned back by the spring E3 into such position that the lugs e can no longer pass through aperture Gr, whereupon the chandelier will be locked in position. In this construction, with the upper tube-section, A, and the sliding tube-section should be combined devices to prevent these tubes from rotating relatively to each other. This may be accomplished by having the tube-section A square and having a square aperture in the upper end, C5, of tube C or tube A may be round and provided with afeather fitting in a groove or aperture in the tube-section C.

By means of the stops L and L', secured to the stationary part of the chandelier, the move- Vments of the rotating parts can be properly limited.

The bar C2 may be rotated by the hand ot' the operator, if desired, as shown in Fig. 6- that is to say, said bar can be extended continuously to the thumb-piece E2, part of it operating as the thumb-piece, and being provided with a handle, such as shown at EG. In this case the returning-spring E3 may be related with the other parts, as shown in this figure.

I am aware that use has been heretofore made of telescoping or sliding tubes having a series of stops on the movable part and a catch on the stationary part, and I do not broadly claim such as my invention; but I believe myself to be the first to construct a chandelier with the details set forth,whereby within the chandelier there are concealed a series of stops or lugs carried by the sliding part, and a stationary collar which both strengthens the stationary tube and stops the sliding section. The devices which have heretofore been used have been unsightly, owing to the defective manner in which the parts have been arranged, whereas when arranged as I have set forth nothing is visible but the tubes and bulbs, which maybe made as ornamental as desired.

What l claim isl. In a chandelier, the combination, substantially as set forth, of the following elementsnamely: the upper stationary tube-section, a cord-winding mechanism attached to said stationarytube-section,ahorizontalandinwardlyprojecting supporting-stop at the lower end of said stationary tube, a lower sliding tube-section, a series of locking lugs or spurs carried by and concealed entirely within the lower section and arranged to be moved laterally relatively thereto, a cord attached to said scries of locking lugs or spurs and to the winding mechanism in the stationary section, means, substantially as set forth, to move said lugs or spurs laterally relatively to the supportingstop to throw them into engagement therewith, and the means which withdraw them to permit them to pass vertically through the supporting-stop.

2. In a chandelier, the combination of an IOO IIO

upper stationary tube-section, a supportingstop attached to said section, a lower sliding tubesection, a series of vibratin g lookin g-dogs carried by the sliding section and arranged to engage with the supportingstop ou the stationary section, and two opposing wedges, of which one is connected by a cord to the stationary section and the other :is connected to the sliding section, said wedges being operated by the weight of the chandelier to crowd the vibrating locking-dogs ,into engagement with the supporting-stop on the stationary section to provide a positive support for the sliding section, substantially as set forth.`

3. In a chandelier, the combination of an upper stationary tube-section, a supportingstop attached to said section, a lower sliding tube-section, a series of vibrating 1ocking-dogs carried by the sliding section and arranged to engage with the supporting-stop on the stationary section, and two opposing wedges, connected respectively to the stationary section and to the sliding section and operated by the weight of the chandelier to crowd the vibratin g locking-dogs into engagement with the supporting-stop on the stationary section to provide a positive support for the sliding section, substantially as set forth.

4. In a chandelier, the combination, with the upper tubesection having an inwardly-projecting shoulder or supporting-surface, B, of the slotted tube-section C2, provided with inclined tion, and the vibrating locking-bar E, of the devices which are operated by the weight ofthe chandelier to move said locking-bar outward, and the stem E', projecting through the bottom of the sliding portion and arranged, substantially as set forth, to permit the vibrating locking-bar to be pushed upward relatively to the sliding portion, substantially as set forth.

6. In a chandelier, the combination, with the stationary section having` a stop, and the slidin g section, of a locking-bar carried by the sliding section, and having a series of stops upon one side and one or more wedges formed upon the opposite side, and wedging devices attached to the sliding section and arranged to crowd the locking-bar outward by engaging with the wedge or wedges on said bar, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses. 4
