27, out through the enlarged eye 34 and then coiled about the rod and tube 41 and then its lower end 28 is connected with the chandelier and spliced in several directions to the conductors for illuminating the incandescent lamps 15.

In order to take care of the proper length of conductor for the various adjustable posi tions of the chandelier, it is preferred to dispose the chandelier so that it is distended to the fullest length from the ceiling or support, at which time the conductor 28 is coiled about the rods 40 and 41 to give it sufficient length. Upon raising the chandelier, the rod 40 will a telescope within the tube 41 and serve as a guide for the coils of the conductor 28, assuring against displacement and preventing any rubbing which may affect the insulation.

For shielding the conductor and its guide,

- the telescopic tubes30, 31, 32 and 33 are fixed between the head 35 and the neck 42 by means of a collar 45, which is screw threaded in the neck 42. The telescopic members 30, 31, 32 and 33 each have at one end thereof collars 46, 47, 48 of the same diameter as the next preceding tube 30, 31, 32 and 33, respectively, and make snug fit but permit slidable engagement with each successive tube. The lower ends of the tubes are provided with enlarged flanges 49, 50 and 51, of a diameter which will give snug but slidable fit within the tubes 31, 32 and 33, respectively.

After assembly of the rod 40, tube 41 and the insulated conductors 28, in coiled position, the telescopic tubes 30, 31, 32 and 33,

which have been previously moved back over the tube 27, are slid down over the assembly of the rod 40, the tube 41 and the coiled conductor so that the last tube 45 may be threadcd into the funnel-shaped neck 42. The tubes similar support, or contracted, the tubes 40 and 41 will guide the excess length of insulated conductor so that this relatively flexible member will conduct the supply of electrical current necessary for illuminating the scopic tubes 30, 31, 32 and 33 will accommodate themseives to any change in length and this, perhaps, coupled with the guide formed by the rod 40 and the tube 41, will hold the chandelier relatively rigidly, as if it were made out of a single suspending member. In addition, also, as the chain 19 is made of flat, ribbon-like members, it will give additional rigidity to the suspension of the chandelier.

Additionally, also, though the chandelier is During this movement, the tele extensible and movable relatively to the support, the wires or insulated conductors will not be in any way visible and the excess length necessary for accommodating the parts to this adjustment will be well protected by the telescopic tubular members which shield and encase this part.

Thus, I have provided an electrical fixture which is readily extensible, to serve on the one hand as a chandelier, when used near the ceiling, but which may be extended to give more direct illumination, as when the chandelier is required to be used for illumination over a table. Thus, ordinarily in a living room, where a light would be positioned at a high level for general illumination, with my chandelier formed extensible as described, the general furniture arrangement may be for that of a dining room and obtain the requisite illumination in effecting this change. At the same time I provide an electrical fixture which will satisfy all the rigid requirements of fire underwriters as to being free from hazard in the handling of a live electrical conductor, to thereby prevent any possibility of fire due to short circuiting of the current. This is obtained by the rigid guide for the electrical conductor, combined with the telescopic tubes. All this is accomplished without in any way detracting from the ornamental appearance of the fixture.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is

1. An extensible lighting fixture of the character described comprising a chandelier, a counterpoise therefor, a guide for said counterpoise, an electrical conductor connecting said chandelier, and including an excess coiled portion, a telescopic connector for said guide and chandelier, and telescopic guiding means for said conductor serving to keep said telescopic member, chandelier and guide in sliding alignment.

2. An extensible lighting fixture of the character described, including a chandelier, means for counter-poising said chandelier in its various extensible positions, a counterpoise guide, an electrical conductor through said guide for said chandelier having an excess length to accommodate the various positions of the chandelier, and aligned connected guiding means for maintaining said chandelier in alignment with said guide, serving as a guide for said excess length of conductor, a telescopic sheath connecting said chandelier and guide and enclosing said aligning means.

In witness whereof I have hereunto signed my name this 26th day of November, 1929.

DAVID SCHAEFER.
