IME/WOR mok/vers To all whom z't may concern:

.A onnrcn.

acitizen-of the 'United States, and a resident -o'f vIdaho JC i'ty in the county ofjBoise and State of Idaho, l ve invented a new and Improved Extensible Electric Light Fixture, of which theollowing and exactrdescription.

My invention reiates particularly to suspended electric light fixtures, and objects is a full, clear,

- of my invention are'to provide `an extensiornamental form.

bi'e fixture in which the electric lights are suspended and counterbalaneed in Aa. novel manner; to provide for the easy adjustment 'of the lights to a higher or lower position; to provlde for housing and concealing the wires in the extensible elements; and' to provi-de a .fixture of the indicated character of a sim le 4construction in which the elements 'are adapted to be produced 'in ther objects of my invention will appear from the particular explanation a'ordi edby the specific-description hereinafter to be gwen.

Reference is `to be hadto the accompanyinjg drawings forming a part of this speci? iication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation of an 'extensible electric light fixture Iembodying my invention; Fig. 2 isa vertical section; Fig. 3 is an enlarged detail view of a portion of `the lazy tongs employedin carrying out the invention; Figs. 4 and 5 are details to be hereinafter referred to; Vand Fig. 6 vis an elevation illustrating adifferent form of the invention.

Referring more particularly to the form illustrated 1n Figs. 1 to 5, a pipe 10 is provided with a casing 11, and connects with a iitting 12 by lazy tongs 13, the tting 12 in practice carrying any approved :form of bracket arms and lamps. The conductor wires 14 extend through the pipe 10 and through the arms of the lazy tongs 13 in the manner hereinafter explained. The lazy tongs are balanced by a counterweight 15 connected by pivots 13*l with the upper arms 13" ofthe lazy tongs 13. Inthe form shown v in Figs. 1 and 2, a lower cross arm 17- is supported at the lower end of the casing 11, and carries pulleys 17a over which vchains 16 run, the said chains at the lower ends maagden ocmw; hun. inspannen maquina, '1919. mi 10.-vagar?.

' bein connected as by eyes' 16 with the -wer ries pulleys 18 over which the chains 16 run,

t'15. -An 'upper cross "arm 18carfrom which'pulleys the chains 11i-run downward and are connected as b eyes 16" with the weight 15. In 'the pre erred arrangement, the weight-15 is in the form of a cup havmg a cover 15, the cup receiving shot 15, or their equivalent, to vary the weight. The cup is secured to a central tube 15 that `surroundsand slides upon the case 11. The

arrangement is such that upon raising or lowering the fit-ting 12 the arms of the lazy tongs 13 will contract or expand, and the upper arms 13" thereof will consequently raise or lower the weight 15. The chains 16 during the movement of the weight run freely over the pulleys on the cross arms 17, 18. The upper arm 18 comprises two side plates 18", which are given a concave-convex form at the center, as at 18, to embrace ashort coupling pipe 20, the lower end of which :pipe has threaded connection with theupper end of a coupling 21, the lower .end of which coupling has threaded connectionwith the upper end. of the pipe 10. At' the upper end of the coupling pipe 20 a second coupling 22'has threaded connection, and is adapted in practice to screw onto a ceiling pipe in the usual manner. The plates T189 of the upper cross` arm 18 are clamped between the upper and lower couplings`21, 22. At the lower end, the main 10 carriesy a short plate 23, to which the adacent arms of the-lazy tongs13 are pivotallyv connected, as by an eyelet 24. The casingl 11 at its lower end is formed with slots 25 (Fig. 4) that accommodate the plate 23. The arrangement is such that by uncoupling the member 21 from the pipe 10 the lazy tongs, the plate 23 and the pipe 10, may be drawn downward from the casing 11 for access to the conductor wires 14 at the lower end' of the said casing. The conductor Wires 14 are housed and concealed Thus each arm, as shown best in Figs.. 2 and 3, is made hollow, consisting of a box 13 and a sliding cover 13d. Each box 13c and its cover 13d is made dove-tailed, as seen clearly in Fig. 2. The box-like arms of the lazy tongs cross as usual, and are pivoted at the center as at 13, and at the ends by eyelets 13, andthe conductor wires 14 runthrough the end eyelets 13t backward and forward 110 y and across each other, following :the direction of the' arms of the lazy tongs. The fitting 12, which in practice carries the brackets or equivalent fixture and the lamps,

is shown in the form'of a T, which. is threaded to a short nipple 27 surrounding which is a casing 28, and the upper end of said nipple is provided with a plate .29 that extends through slots 30 (Fig. 5), in a manner similar to the plate 23 and slots 25,

- previously referred to.

-from a ceiling fixture 22 of anyapproved design, by a pipe the same as previously described, the pipe having a housing 11,- the connection between the suspended pipe and the lazy tongs being eifected as by a plate 23a. The upper arms of `the lazy tongs extend on opposite of the plate 23, and are united to the plate and to each otherby an eyelet 23". Similarly, the lowerarms ofA the lazy tongs are united to a plate 23, byan eyelet 23d.

Having thus described my invention, I claim as new and desire. to secure by Letters Patent:

1. An extensible electric light fixture, comprising a fitting for carrying the lights, a lazy tongs carrying said fitting, and means for suspending said lazy tongs, said lazy vtongs comprising box-like arms having movable covers, said box-like arms being arms of the lazy tongs being of box-like form and each havin a sliding cover, the

cover and the body o the arm being dovetailedl in cross section. e

3. An extensible electric light fixture, comprising a fitting adapted to carry the electric lights, a lazy ton s, suspension means for said lazy tongs lan connected with the upper v end thereof, said,suspension means including a pipe to receive the conductor wires, an arm in fixed relation to the pipe, a slidin tubular vweight surrounding lsaid pipe, pul eys on the cross arm, and flexible elements 'connected with said weight running on thesaid pulleys and having connection with members movable as the lazy tongs are contracted or expanded.

4. An extensible electric light fixture, comprising a pipe adapted to receive conductor wires, means for suspending said pipe, a lazy tongs,a fitting adapted to carry electric lamp-supporting means, means for conneet-ing said lazy tongs with the mentioned pipe and fitting, said' means including a plate carried by said pipe, and a plate carried by said-tting, said pipe and said fitting having casings formed with slots in which the respective plates mentioned are received.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

FREDERICK GARRECHT.
