EXTENSIBLE CHANDELIER.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed March 1, 1907. Serial No. 360,004.

' To all whom it may concern.

Be it known that I, WALTER I. WILSON, a citizen of the United States, and a resident of Los Angeles, in the county of- Los Angeles and State of California, have invented a new and useful Extensible Chandelier, of which the following is a specification.

The object of the invention isto produce a practical, simple, cheap, and durable extensible chandelier which may ed to different heights.

I attain these objects by the mechanism illustrated in the accompanying drawings in which H -Figure 1 is a vertical sketch of the entire fixture drawn partly in perspective and partly in section. Fig. 2 is a vertical View of the coils which extends from one end of the fixture to the other. Fig. 3 is a top view of the body of the fixture. Fig. 4 is a vertical section of the body. v Fig. 5 is a top view of the head and adjacent parts, showing the method of bringing conductors out. .Fig. 6 is a vertical section of the head and adjacent parts. Fig. 7 is a section of the friction device collar stop and' bushing. Fig. 8 is an enlarged vertical cross section on line r x Fig. 3, showing the construction of parts adjacent thereto. Fig. 9 is an enlarged vertical cross section on line rx Fig. 3, showing the construction of parts adjacent thereto. Fig. 10 is an enlarged vertical section similar to Fig. 7 showing a modification in which a greater number of-telescopic tubes are employed.

The tubing may most clearly be designated as '1 being the 1st or inside tubing, T being the 2nd tubing from the center, T being the 3rd from the center and T being the 4th from the center.

Fig. 2C represents the conductors which carry the current from the top of the fixture to the extensible light or lights. This conductor 'may be what is known as lamp cord size #18, the two strands being separated and wound side by side around a rod close together. Thewhole thing is then pushed into the wire guard W, then the rod withdrawn. This wire guard W is a very small single wire with its coils wound close together and Guard W should e made of the very best steel wire such as piano wire The function of the guard W is principally to protect C from being worn or .becoming tangled or catching on the tension device at the top of T The be easily adjust- T" is screwed or soldered.

-to keep T in place an upper end of the guard W is made fast to the upper end of T as is also CE, The lower end of the guard V is made fast to the lower end of T as is also C By this arrangement you may pull T almost out of T and have a disinterrupted circuit from the top end of T to the bottom end of T Any number of tubes telescoping one within the other may be used as shown in Fig. 10 by providing a similar stop as S and a similar friction as shown in Fig. 7 and another tube T inside of tube T and attaching one end of the coils to the adjacent end of the smallest tubing and the other end of the coils to the adjacent end of the largest tubing. This fixture may be screwed to the ceiling, wall or floor as the case may demand. A distributer connection B is arranged at the lower end of the tube T and has an internally threaded a11- nular up er portion M into which the lower end of tu e T is screwed, and having an internally threaded lower ortion N of less diameter, into which the ower part of tube The distributer connection is provided with two segmental openings 0 as clearly shown in Figs. 3 and 9.

.The outer tube T is arranged with its lower end posting with the annular portion M. The distributer connection has two threaded orificesP which communicate with the open ings 0 respectively, and is also provided with two threaded orifices Q which pass entirely through the wall of the connection B but do not communicate with openings 0. gas channel is formed between tubes T and T with which gas channel gas arms A communicate, the latter being screwed in. orifices Electric light arms A are screwed in the orifices P. The lower end of tube T extends below the body B and a stop S is screwed to the extreme lower end of tube T.

Fig. 5 and Fig. 6 represent the head or casting H. The lower portion has two threaded portions, the smallest is screwed into the top of TFand the larger threaded portion is'screwed into the top of T thus' giving a channel for the gas out through the channel G and duct G. R represents a clamp ring, having a depending bead R and set screw D which is sh ped on the head H (i also conductors C and C The top end of H may be threaded 7} standard so as to fit in any ordinaryfitting. Fig. 7 shows a section of the friction device which consists of slotting the upper end of 'l. then by slipping the end on a mandrel and pounding it until it is swelled so as to llOlL about three times the required weight.

Then threading the lower portion of the slotted nation and screwing on the collar li un til the friction is reduced to just a little more than what is required to hold up the extensible parts.

Fig. 7. The lower part shows the stop S and the bushing F. The stop S is screwed upon the lower end of T to prevent T from pulling out when being extended. Bushing F is a guide for T and should be made of some semi-hard substance, such as fiber or hard leather, so as not to scratchaml disfigure the platin r on T When the friction becomes worn al that is necessary is to unscrew stop S and pull T out as far as the col lar K, then with a pipe wrench or a pair of gas pliers, unscrew collar K until youget the required friction.

The sketch shows but one light L, being extensible. However, any number of lights may be attached to the extensible part in any manner seen fit. If it is so desired, the two electric lights L shown to be stationary may be omitted in that place entirely or attached to the extensible part, by using a body something like casting B, Figs. 3 8c 4. If what is termed as a strai ht electric fixture is desired, the gas arms may be omitted, also tubing T". if all three electric lights are desired to be extensible casting B furnished with lights L may be screwed onto the lower end of T Tubing T and T" may thenbe omitted.

I claim:

1. in an extensible chandelier, a distributer connection having an annular u per por- 40/ tie. for the attachment of tubes 3 and T",

and having a'lower portion of less diameter for the attachment of tube T and having segmental openings with threaded orifices communicating therei *ith for the attachment of electric light arms, and having threaded orifices which pass clear through the wall of .the distributor and communicate with the space between tubes T and T for the attachment of gas arms.

2. In an extensible chandelier, a head having a hexagonal portion and a threaded flange below the hexagonal portion, a threaded extension below the flange and of less diameter, a tube fastened to the flange, an inner tube fastened to the threaded extension thus forming a space between said. tubes, said head having a gas duet extending from the top and offset to'communicatc with the space between said tubes, said head having a n0 passage extending from the bottom and havlng an oiiset communicating with the exterior of the head to enable a conductor being extended from externally or the head into the inner tube.
