ELECTRIC CONNECTION FOR CHANDELIERS.

SPECIFICATION forming part of Letters Patent No. 348,708, dated September 7, 1886.

Serial No. 193,909. (No model.)

To all whom, it may concern.-

Be it known that we, JOHN P. XVILLETS, of Jersey City, in the county of Hudson and State of New Jersey, and EDWIN R. ORoLIUs,

of New York city, in the county of New York and State of New York, have invented a new and Improved Electric Connection for Chandeliers, of which the following is a full, clear, and exact description.

Our invention relates to the construction of an apparatus designed to maintain a continuous electric connection between the main-line wires and the lamps or lighting apparatus carried by a chandelier that is suspended by means I 5 ofaball-and-socket joint; and to theend named our invention consists of two metallic rings insulated the one from the other but connected with the Inain-line wires, one of the rings being connected with the main-line wire leading to, while the other is connected to the wire leading from, the chandelier, each ring being in yielding electric communication with wires carried by the swinging portion of the chair delier, the insulated rings being held and supported by the stationary coupling or by the gas-supply pipe; and the invention further consists in the arrangement of an auxiliary bushing of insulated material whereby the chandelier is insulated from the system of gassupply pipes.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a vertical sectional view of our improved electric connection for chandeliers, the View being taken on the broken line a a: of Fig. 2. Fig. 2 is a plan View of the apparatus illustrated in Fig. 1. Fig. 3 is a sec tional plan View taken on line a a of Fig. 1.

Figure 4 is a sectional View taken on line 3 y of Fig. 2, and Fig. 5 is a detail view illustrating a modified construction for establishing a yielding connection at the point where 5 the ball-andsocket joint is located.

In the construction illustrated in the drawings above referred to, A represents a unioncoupling by which connection with the gassupply pipe is established, and to which there is connected the cup or socket B, within which there is fitted the ball 0, the two parts constituting a ball-andsocket joint, the movable or swinging pipe D, to which the chandelier is directly connected,being carried by the ball 0, connection between the parts being established 5 5 in the ordinary manner, except that between the ball 0 and the main bushing a there is interposed an auxiliary bushing, E, said bushing being made of anyproper non-conducting material, the idea being to insulate the chan- 6o delier from the system of gas-supply pipes.

A ring, F, made of any suitable non-conducting material, is suspended from the coupling A by means of arms b b and a ring, 0, to which the arms are secured, the ring 0 being formed 6 to fit closely about the upper portion of the coupling A, to which it is held by set-screws d or by any other suitable holding attachment. The ring F carries two metallic rings or hoops, cf, that are in electric communication with the the main-line wires I I, said wires being made fast to binding-posts or contact-plates K K, between which and the hoops there are interposed wires 2' i, made from any form of fusible metal, direct contact between the rings or hoops ef and the wires 2' being established through the medium of plates g g, the plate 9 being fixed to the upper face of the ring F and extending downward over the inner face of said ring to rest against or upon the hoop e, while the plate 9 extends down upon the outer face of the ring F into electric connection with the hoop f.

Upon the tube or pipe D there is rigidly mounted a plate, G, made of any suitable non- S conducting material, and upon each end of the plate G there is arranged an upwardly-extending sleeve, as H, within which there are mounted metallic bars I and 0, the upper end ofeach bar being grooved to fit against the lower edge 9:) of one of the hoops e orf, the bars being held against the hoops by spiral springs 92, the upper ends of the springs being fixed to the bars while the lower ends are held by screws 1), which screws also serve to hold the sleeves to the plate G. It will be understood that the bars I 0 are free to slide in the sleeves H, and it will be seen that the bar Z extends directly upward to rest against the hoop 6 while the bar 0 is bent outward and then upward to rest 10o against the hoop f. Wires '1 T lead from the sleeves H to the electric lightsor gas-lighting apparatus carried by the chandelier.

From the construction described it will be readily understood that the chandelier will be free both to swing and to turn upon its connection with the gas-supply pipe without interfering with the electric connection between the apparatus which it carries and the mainline wires.

In Fig. 5 I illustrate aconstruction wherein the use of the sliding bars Z or 0 is dispensed with, the place of the bar being taken by aspring strip so bent that it will always be held under tension by the hoop with which it engages, as will be readily appreciated from the construction shown. 1

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with a ring of insulat ing material, of metallic rings or hoops carried thereby, and yielding contacts held against said hoops, substantially as described.

2. The combination, with the fixed and movable portions of a ball-and-socket joint, of two insulating-ring carried by the stationary portion of said joint, metallic hoops carried by said ring, and yielding contact-s arranged in connection with said hoops and carried by a plate that is fixed to the movable portion of the ball-and-socket joint, substantially as shown and described.

4. The combination, with a ring, F, carrying automatic cut-outs, substantially as described, connecting-plates g g, and hoops e f, of a plate, G, bars Z and 0, and springs n n, the parts being arranged 'in connection with a ball-andsocket joint substantially as described.
