LIGHTING OF TABLES AND THE LIKE BY ELECTRICITY.

SPECIFICATION forming part of Letters Patent No. 453,871, dated June 9, 1891.

Application filed February 24, 1891. Serial No. 382,479. (No model.)

-outside the table either above or below, so

that the Wires and connections are not only visible, but are liable at any time to damage. According to the present invention I am able to connect the portable or other incandescent table-lamps or Candelabra used with the electric house-mains without the use of visible flexible connections.

To clearly explain thenature of my invention I will describe it in connection with the accompanying drawings, in which- Figure 1 is a sectional elevation of a table fitted with my improvements. Fig. 2 is a plan of same. Fig. 3 is a view showing detached leaves. Fig. 4 is a sectional elevation, on an enlarged scale, of a bolt in one of the legs, by which connection is made with the housemains. Fig. 5 is an elevation of that part of the leg. Fig. 6 is a plan taken on the line X X, Fig. 4. Fig.7 is a sectional plan ot one of the thimbles or sockets in the table-leaves, by which the connections are made between said leaves. Fig. 8 is a face view of same. Fig. 9 is a` sectional elevation ot one ot the split plugs which engage with said thimbles. Fig. 10 is a fac@ view of same. Fig. 11 is a longi` tudinal section through one ofthe tableleaves, showing the wiring of same and the plugs upon which the Candelabra or lamps are fixed. Fig. 12 is a transverse section of same, and Fig. 13 is a plan. Fig. 14 is a longitudinal Section showing another means of moving the table-leaves, and Fig. 15 is a transverse section of saine.

I form in the table top 0r leaves channels 1,in which are laid the conductingwires, said wires being attached by binding-screws 2 to metal thimble-pieccs 3, let into the wood-work of the table, and to split plugs Li, respectively, the plugs being all placed on one side of the leaf and the thimbles on the other, as shown in Fig. S. At the points on the leaves of the table where it is desired that the lights shall be placed I let in pairs ot metal blocks 5 5, secured to a vulcanite base G, each block receiving, respectively, the ilow and the return current wires which are attached to same by the binding-screws 7. These blocks 5 5 are adapted to receive movable plugs S S, upon which the Candelabra are placed, a pair of sockets being provided in each of the latter to receive them. These plugs may beremoved, so that the surface ot the table-is not interfered with. The conducting-wires are carried down channels 9, Fig. Li, in the legs of the table, and are attached to the binding-screws 10 of a metal bolt-casiug, which is let into same. This bolt has a casing 11 anda bolt portion proper 12, which is preferably split and which is adapted to enter a socket 13 in the iioor, said socket being insulated by a vulcanite plate 14 or in other ways, as desired. This socket is connect-ed to the main wires of the house, so that it is only necessary to torce the bolts into connection with sockets to send the current through the table-lamps.

The bolt 12 has a handle 11 and lis normally kept out of contact with the socket by a spring 15, which presses against the disk-head 16 of same. A right-angle slot 17 is provided in the leg of the table tor this handle to move in, so that when said handle is pressed down a partial turn is given to it. The slot will serve to hold it in position.

In Fig. 14 I show a modification olf my invention, in which, instead ot' forming channels in the table-leaves for the conductingwires, I atlix casings 18 beneath saine, each casing being constructed to carry a pair oit' wires, as shown. These casings terminate in the thimbles 3 and split plugs 4E, and at intermediate points in saine are provided with the blocks 5, which are let in between same and screwed to the table, through which their plugs 8 project.

It will be evident that where the table is not an extending one and has, consequently, no loose leaves the connecting thimbles and plugs are n ot required,and it will also be un- ICO derstood that my invention is not confined to the particular construction of parts shown in the drawings.

Vhat I clairn is l. A- table having' channels in the top and legs of same, electric conductors carried in said channels, bolts in the legs connected to said conductors for making` contact with sockets connected. to the electric house-mains, and blocks placed in the circuits and provided with means for receiving candelabra or lamp fittings, substantially as described.

2. A table wired with electric conductors,

means for connecting' said conductors to the electric house-mains, split plugs, and tlliinbles carried by the leaves of saine and connected with said conductors, and blocks in the circuit provided with means for receiving eandel abra or lamp fittings, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing` witnesses.
