Specification of Letters Patent.

Application filed April 2, 1910. Serial No. 552,961.

To all whom it may concern:

Be it known that I, CYRUS C. KENNEDY, a. citizen of the United States, residing at South Rock Island, in the county of Rock Island and State of Illinois, have invented new and useful Improvements in Extensible Electric-Light Chandeliers, of which the following is a specification.

This invention relates to lighting fixtures and more particularly to an extensible electric light chandelier' of that type of which the electric cord conductor is arranged within the telescoping tubes of the chandelier.

The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively simple and inexpensive to manufacture, reliable and efficient in use, composed of few parts and readily adjustable in raising or lowering the lights.

Another object of the invention is the provision of means for locking the telescoping tubes or pipes together in any desired position of adjustment and at the same time preventing relative turning of the tubes.

With these objects in view, and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention; Figure 1 is a side view of the chandelier; Fig. 2 is a front view of the telescoping portions of the chandelier. Fig. 3 is a longitudinal section thereof. Fig. t is a horizontal section of the chandelier at the locking dog.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, 1 designates the fixed outer tube or pipe of the chandelier, which is fastened at its upper end to a ceiling or other support and slidable in the lower end of this tube is the lamp supporting tube 2, the latter having arms 3, which hold the incandescent lamps 4l. The tube 2 can be raised and lowered for placing the lights in any desired position, the weight of the tube 2 and attached parts can be counterbalanced by a spring 5, or equivalent means, anchored in the outer tube l.

The tube 1 has a longitudinal slot 6 through which projects a key or pin '7 on the upper end of the inner tube, whereby relative rotation of the tube is prevented, although free relative longitudinal movement is provided. On the lower end of the outer tube is a latch or dog S, which is pivoted between lugs 9 on a ring or band 10 embracing the lower ends of the tube, and this dog has a lateral extending pin or projection 11 that is disposed in the slot G and is adapted to engage in any one of a plurality of spaced openings 12 in the inner section or tube 2 of the chandelier'. The dog is held in locking position by a leaf spring 13, which is fastened on the tube 1 and projects downwardly beyond the band a'nd slidably engages at 14, the inner face of the dog at a point below the pivot 15 thereof so that the lower end or linger piece 16 of the dog or latch will be held outwardly while the outer end that carries the pin l1 will be held inwardly. This pin l1 cooperates with the pin 7 on t-he inner tube to rigidly hold the tube 2 from rotating. By pressing inwardly on the finger piece 16 of the latch, the pin 11 will be withdrawn from the opening 12 in which it engages, and while the latch is thus held retracted, the inner tube can be raised or lowered until the proper position for the lights is obtained and the lights will be locked in this position by the pin 11 of the catch engaging in the opening 12 opposite the same.

'Ihe flexible or other cord conductor 17, which supplies the current to the lamps is of sufficient length to permit the section 2 of the chandelier to be freely raised and lowered through the range of adjustment. The conductor leads into the upper end of the upper tube and passes through a disk 1S in the upper end of the inner tube and continues downwardly to the lamp-carrying arms of the chandelier, where connections are made with the lamps in the usual man- The cord is rigidly fastened in the disk and cannot slip therethrough but the portion of the cord above the disk is free to coil up in the upper tube, the bore of which forms a chamber for the cord conductor. The disk is held in the inner tube in any suitable manner, as, for instance, by the same pin 7 that locks the sections of the chandelier against rotation.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation Will be readily apparent to those skilled in the art to which the invention relates, and While I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are Within the scope of the claims.

That I claim as new and desire to secure by Letters Patent iszl. A chandelier of the class described, comprising a tubular ceiling section, a tubular lamp-carrying section telescoping in the ceiling section, said ceiling section having a longitudinal slot, a spring pressed latch pivoted on the lower end or' the ceiling section and having a pin extending into the slot, said lamp-carrying section having spaced openings into any one of which the said pin is adapted to engage, a pin on the lampcarrying section engaging in the said slot for cooperating With the latch pin to prevent relative turning of the sections, a cord conductor extending through both sections, and means in the upper end of the lampcarrying section to which the cord is rigidly secured, the portion ot' the conductor above the said means being adapted to coil and uncoil in the ceiling section during theJ moveA nient of the lamp-carrying section.

2. A chandelier of the class described, comprising a tubular ceiling section, a tubular lamp-carrying section telescoping in the ceiling section, said ceiling section having a longitudinal slot, a spring pressed latch pivoted on the loWer end of the ceiling section and having a pin extending into the slot, said lamp-carrying section having spaced openings into any one of Which the said pin is adapted to engage, a pin on the lampcarrying section engaging in the said slot for cooperating With the latch pin to prevent relative turning of the sections, a device secured in the lamp-carrying section by the last mentioned pin, and a cord condu'cton fastened to the said device and extending through the sections for connecting the lamps of the chandelier in circuit, the said cord conductor being adapted to coil and uncoil in the portion of the ceiling section above the upper end of the lamp-carrying section.

In testimony whereof I affix my signature in presence ot' two Witnesses.

CYRUS C. KENNEDY.
