ELECTRIC-LIGHT FIXTURE.

SPECIFICATION formingpart of Letters Patent No. 418,636, dated December 31, 1889.

Application filed October 16, 1889. Serial No. 327,179. 7 (N0 model.)

To all whom it, 17mg concern:

Be it known that I, GEORGE C. BAILLARD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and use-1 ful Improvements in Electric-Light Fixtures, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the construction of what may be termed a combined adjustable suspension device, lamp -holder, and shade-holderfor incandescent electric lamps, the object being to obtain a device which will; in a simple manner permit the suspension of the lamp and shade, or either of them, by the two conducting-wires in such manner that the height of the lamp may be readily adjusted to suit circumstances, and at the same time afford a reliable means of attaching the lampsocket and shade or reflector.

To these and other ends my invention consists in the combination and arrangement of parts, substantially as hereinafter fully described and claimed.

In the drawings which form part of this specification, Figure 1 is an elevation of the complete suspension device, showing it in connection with a lamp and shade holder, akeysocket, lamp, and shade. Fig. 2 is a vertical section of the same on a reduced scale, without the lamp. Fig. 3 is a similar section of a simple and compact adjustable suspension device adapted for holding a lamp having a keyless socket. Fig. 4 is a vertical section of a device similar to'that shown in Fig. 3, but

with shade-holding flange.

I first construct the pendant 1, which will generally be of a general bell shape, having the internal recess 2, the solid head 3, and the shade-holding seat 4, through the flange of which are fitted two or more clamp-screws 5. In the head 3 I bore a central perforation 6, to meet an inclined channel 7, passing out laterally through the head. I bore another channel 8 horizontally into the head from the outside, so as to meet a recess 9 in the under part of the head. These channels form a devious passage for the flexible conductors 10,

which carry current to the lamp. The conductors pass first through the passages 6 '7, then out around and into passage 8, and thence by recess 9 to the lamp-terminals in the socket 11. In the design shown at Fig. 1 the lampsocket is one fitted with a switch and turn-off. The key 12 and the socket are maintained in position in the pendant lby means of the bayonet-slot 13, cut in the wall of the latter. The friction developed on the flexible conductors 10 by the channels above described is more than sufficient to firmly hold the entire fixture, including the lamp and shade, at any position to which the pendant may be placed thereon. To change its position it 1s only necessary to take hold of the loop extending between the channel 7 and channel 8 and slide the pendant 1 upwardly or down wardly on the conductors 10, and it will remain in any position thus obtained without placing any tension on the conductor between the channel 8 and the terminals in the lampsocket. The key 12 of the lamp-socket projects outwardly at a convenient point, so that it may be as readily operated as if the pond ant l were not present, and by using it as a means of locking the lamp-socket into the pendant 1 I am able to dispense with the usual metal base-piece to which the various parts of the lamp-socket are attached, and thus effect some slight saving'in the cost of the total fitting. Such a base-piece is shown at 1 1 in Fig. 3. i

In the latter figure is shown. the manner in which I adapt my invention to a keyless socket. In this the pendant 1 is somewhat different in general shape and its recess 2 is made much smaller, so as to fit the usual projecting end 15 of the socket-base 14. An internal bayonet-slot 16' is constructed for the reception of the screw 17, or in the absence of such usual form of clamping-screw a pin may be placed on the 'socket-base, so as to ennels 6, 7, 8, and 9 for the passage of the flexible conducting-wires by which the device is to be suspended.

The lamp-socket being firmly held in position in either case, the lamp itself may be removed with great facility and replaced as often as circumstances may require.

In Fig. l the pendant l is constructed asin Figs. 1 and 2, with a flange formed with shadeholding seat at and clamp-screws 5, so as to receive and firmly hold the shade or reflector.

Obviously the construction may be considerably varied with respect to the particular direction and angles of the friction-channels in the pendant head 3, as also in the configuration of the pendant itself externally. In the latter respect a great variation is permissible, so as to have the pendant correspond with any desired character of ornamentation. The pendant may be made of wood, rubber, vulcanized fiber, or any other material which lends itself to the construction. In some cases it may be to advantage constructed of glass, and in that event the shade may be made integral with it.

In the drawings and in the above description I have illustrated the invention as used in connection with the form usually known as the IVestinghouse socket, but obviously I am not confined to any particular style of lamp-socket, as the invention is quite as readily adaptable to any of the forms of lampsocket which are now or hereafter may be in use. I therefore do not confine the scope of my invention toany special form of lampsocket, whether the same be used with or without a key-switch.

I claim as my invention- 1. In incandescent-light fixtures, the combination, with flexible conductors, of a friction pendent block adapted to slide thereon, provided with a recess for a lamp-socket and means of attaching the same.

2. The improved electric-light fixture, comprising a pendent block provided with means of frictional suspension on flexible cords, a seat thereon for the reception of a lampsocket, and a retaining device-such as a bayonet-lockfor the lamp-socket.

3. The improved electric-light fixture, comprising, in combination, a pendent block provided with means of frictional suspension on flexible cords, a recess therein for the reception of a lamp-socket, and a shade-holder adapted to receive and retain a shade or re- Hector.

4:. The improved electric-light fixture, consisting of a pendent block having a receptacle for a lamp-socket and provided with means of retaining the same, and havingafrictional channel for the passage of the suspension cord or conductors.

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

GEORGE O. BAILLARD.
