* UNITED STATES PATENT OFFIC DEXTER W. PARKER, OF MERIDEN, CONNECTICUT.

EXTENSION-CHANDELIER.

SPECIFICATION forming part of Letters Patent 278,359, dated May 29, 1883.

i Application filed March 13, 1883. (No model.)

To all whom at may concern Be it known that I, DEXTER W. PARKER, a

citizen of the United States, residing at Meriden, in the countyof New Haven and State of Connecticut, have invented certain new and useful Improvements in Extension- Chandeliers; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being .had to the accompanyin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention is an improvement on my Patent No. 269,105, granted December 12, r 1882 and it consists, chiefly, in means for antomatically actuating the clamping wedge thereinshownand described, the said means serving also for the suspension of the movable part of the extension-chandelier, as hereinafter set forth. I

It further consists in'certain details of construction and combination, which will be stated in the appended claims.

In the accompanying drawings, Figure 1 represents a vertical section of a chandelier embodying my present invention; and Fig. 2 represents a perspective view of the canopy or hanger and the devices within the same.

A designates the center box of a chandelier, to which the arms B are attached, and which is hung on the movable tube C,that slides over the solid upper part or rod, D, of the fixture. This rod is secured to canopy or hanger E, and the latter is provided with an eye or stirrup, F, at the upper end of an arm, G, whereby the pipe extending downward therefrom. All the attachments above referred to are preferably made detachable.

The devices for clamping the bottom plate of the center box against the chandelier-arms and for allowing the free vertical movement of the finger-bar need not be described here, as they differ but -little from those shown and claimed in a pending application.

The. incline case G on the upper end of tube 0 is constructed and arranged substantially as in myPatent No.'269,105, above mentioned,

otherwise be practicable.

[ and the shoe H and wedge I operate substantially on the same principle as in that patent, although the inner face of said shoe is provided with serrations h to give it a better hold on the rod D. The cord K, which is the means of connection between said wedge and the finger-bar L, extends down through tube 0, as in ,saidpatent, and is used for the same purpose;

but instead of attachingits upper end directly to the wedge I it is attached to the lower inwardly-bent end, 'i, of a rod, I, extending down from said wedge, This end 2" passes through a Vertical slot, 0, in thenpper end of tube C. This construction of said parts allows said tube to be made of smaller diameter than. would In said patentthe wedge is shownas forced upward by a small spring surrounding the cord or rod K and within the movablelower tube. Of course said spring has no eflect in sustaining the tube itself. In my present invention, however, Ieniploy a strong clock-spring, M, arranged with in a revolving barrel,N, which turns on a shaft or bar held in supports 0 within the canopy or hanger E. A chain, P, is attached at its upper end to said barrel and at its lower end to said wedge. The stress of the spring on said chain tends notonly to lock the outer tube and the inner rod together, but to prevent the former from falling. When the cord K is drawn upon from below, the spring is overcome and the wedge temporarily dislodged. There is then neither frictional nor resilient resist ance to the descent of the tube C. When the operator releases the cord the spring M resumes its duties both 'as an automatic clampoperating device and as a suspending device.

To make the pull of the chain P vertical a hearings in the lower part of thecanopy at a guide-pulley, Q, is employed, which turns in point almost directly over the wedge. The chain passes up through a slot or opening in the bottom of said canopy to the inner side of said pulley, then over the top of the same, and around the barrel N. As this chain is fully exposed to view, the extension-fixture cannot be turned ortwisted in any way without detect-ion.

It thus constitutes a gage for determining the accuracy of arrangement of the other devices forming part of the extension-chandelier, and, being outside of the central line of upright dc vices, is, morever, preserved from the twisting and straining which often injure cables and chains that pass down within the tube.

The construction above described is cheaper than the common one, which uses an inside slotted tube and a middle tube having a stud tures as well as with chandeliers.

What I claim as new, and desire to secure by Letters Patent, is-

1. A clock-spring and revolving barrel located in a chandelier-canopy, in combination with the movable lower tube of the chandelier, and a'chain attached to said barrel, by which said movable tube is suspended, the construction and arrangement of the parts being such that the said chain passes in proximity to the stationary part of the chandelier-fixture, but outside thereof.

2. A chandelier-canopy having a guide-pulley journaled in its slotted bottom, in combination with a clock-spring and revolving barrel located within said canopy, and a chain at-' tached at its upper end to said barrel and suspending the movable part of the chandelier 5 from its lower end, said chain being guided by said pulley on the inner side of the latter, so as to be in proximity to the upper part of the chandelier-fixture, though exterior thereto.

3. In combination-with the movable part of 40 a chandelier and the wedge which looks it to the fixed part thereof, asprin g and chain which operate on said wedge to lock the parts of the chandelier together, and also to suspend the lower part thereof, the parts being so arranged 4 5 that the chain will be outside of said chandelier, though in proximity thereto. 4. A canopy and a clock-spring, barrel, and

guide-pulley, the latter being journaled in the bottom of the canopy, in combination with a 50 fixed upper part of a chandelier-fixture, a movable tube, to which the center box is attached, and a chain which extends from said barrel to said movable tube and is guided by said pulley so as to pass in proximity to the chandelier, but outside thereof, substantially as set forth.

In testimony whereof I afl lx my-signature in presence of two witnesses.

DEXTER W. PARKER.
