SPECIFICATION forming part of Letters Patent No. 671,338, dated April 2, 1901.

Application filed September 10, 1900. Serial No. 29,581. (No model.)

T aZZ whom it may concern:

Beitknown that I, JULIAN ADOLPHE HAL- FORD,a citizen of England,residing at 22 Ohepstow Villas, Bayswater, in the county of London, England, have invented certain new and useful Improvements in Conductors and Contacts for Electrical Glow-Lamps, (for which I have applied for a patent in Great Britain, dated April 10, 1900, No. 6,727,) of which the [0 following is a specification.

Electric glow-lamps and stands for them have been made having their leading-in wires connected to a pair of conducting-spikes, and tables, boards, and othersurfaces have been made with pairs of covered penetrable conducting-strips laid side by side onthem, the strips of each pair connected to opposite "terminals of a source of electricity, so that on thrusting the two spikes of a lamp or its stand one into each strip they make contact and the lamp becomes at once suppliedwith current.

The present invention relates to the construction of conductors for supplying with current lamps, stands, or other connections each provided with a pair of spikes of the kind above referred to, the main object of the invention being to provide in apartments, shop windows, advertising sites, or other places convenient, means of placing glowlamps at various points and in various orders along conducting-lines, as will be described with reference to the accompanying drawings.

Figure 1 is a side view of aglow-lamp supplied by a conducting-bar, which is shown in section. Fig. 2 is a plan view illustrating a base or board provided with the conductor shaped to form a letter P, with the covering therefor removed, the position of the lamps being indicated in dotted lines. Fig. 3 is a section of a flexible conductor or cable with a suspended lamp attached to it.

In the several figures like letters are employed to denote like parts.

Referring first to Figs. 1 and 2, a support 5 or strip of wood a is grooved to receive two parallel conductors, each consisting of a bundle b of fine wires, of copper or other good conducting metal, each bundle being inclosed in a non-conducting penetrable sheath, such as asbestos or other comparatively loose fabric.

Between the two grooves holding the conductors there is a middle groove in which is fixed a partition 0, of non-conducting materialsuch, for instance, as wood or vulcanized fiber. The conductors and partition are covered by a band d of easily-penetrable non-conducting materialsuch,for instance,as the floor-cloth, which consists mostly of cork-dust.

Anywhere along the support or conductingbar alamp Z can be placed, its spikes pene- 6o trating the cover (1 and the wire bundles b, which are connected, respectively, to the opposite terminals of a source of electricity.

As shownin Fig. 2, a board e may be grooved according to a pattern, such as the letter P,

the groove and their contents and cover being like those described with reference to Fig. 1.

The head of the lamp Z is preferably made with a head-ring r, to which the fingers can be applied for pushing the lamp onto the support or conducting-bar, and with an annular projecting rib t, which when the lamp is pushed onto the support or conducting-bar seats itself in the yielding material of the cover (1 and prevents entrance of damp.

The flexible support or conductor (shown in Fig. 3) consists of the two wire bundles I), each with an insulating covering and between them a non-conducting partition 0, the whole inclosed in non-conducting flexible and penetrable material 19 and tape q, varnished or otherwise waterproof. The lamp having a ring 1 for pushing it into place is secured in position by a spring-clip s or otherwise.

Having thus described the nature of this invention and the best means I know of carryingout the sameinto practical efiect, Iclaim-- 1. A support, a pair of insulated bundles of conducting-wires mounted therein, a cover 0 for the said wires, a lamp, and a pair of spikes carried by said lamp and adapted to penetrate said coveringand bundles of conductingwires.

2. A flexible support, a pair of insulated 5 bundles of conducting-wires mounted therein, a non-cond ucting penetrable covering for said bundles, a lamp, and a pair of spikes carried by said lamp and adapted to penetrate said covering and bundles of conducting-wires.

3. A flexible support, a pair of insulated bundles of conducting-wires mounted thereon,
