FIXTURE-BODY SWITCH.

Application filed June 25, 1924. Serial No. 722,398.

and supported by a chandelier, electrolier or other type of fixture, although it is evident that it may be used in any location where it is desired'to close or open an electric circuit by means of a pull chain type oi switch.

It is an object of this inventionto provide in a fixture body switch a novel means for supporting the switch within a protective housing.

Itis another object of this invention to provide a supporting means for a fixture body switch whereby the swltch proper freely supported and relieved. from any strain due to the weight of fixtures which maybe attached'i beneath it.

It is a further ob 'ect otthis invention to provide in a fixture body switch a combined chain guide and means for holding the completed structure assembled.

The invention maybeibest understood by reference to the accompanying drawings taken'together with the following description.

In the drawings:

:Inl'lligure 11 there is shown a commoniorin of electric fixture ,orelectrolier having arranged withinthe:ornaniental tube 10 the supporting "pipe or conduit 11 which is adapted to-cai'rythe weight of the fixture from "a "hicliey or other attaching device mounted'in a conduitbox or similar device on the'celling or wall. The'upper portion of thecanopy.lQ issupported from the tube 10 and serves to support the radiating arms l which may be of any dcsiredninnber or style, carrying at their ends the lights. The

yvires to supply current to the lights pass between the tube 10 and the pipe 11 and are connected to wires passing through the radiating arms 13, within the canopy 12. It is often desirable to be able t-o turn oil or on all of the lights on a fixture at one time without going to the unwarranted expense of in stalling wall switches,or where such a switch cannot be readily installed, such as in rewin ing old houses, and for this purpose the switch 1d ofthis invention is shown mounted in th e canopy 12, supported from thepipe ll. and having the chain 15 by means ofwhich the switch can be manipulated. This chain can be liurought outithrough a tube such as 16 so that it will hang directly below the canopy 12. i

The tube; 16 as will be seen by reference to Figure 1 provides means for supporting the lower portion of theczinopy 12 and its associated parts by means of the knob or sleeve 17 passing over the tube 16 flHCll'JGlDQ connected therewith by means of a set screw 18. In ore or to relieve the switch proper from any. strain due to supporting this Weight, there is provided means to directly connect the tube 16 to the pipe 11 and to allow the switch to float within this means in order to more readily protect it. r

This supporting means comprisesthe 1netallic structure l9,best shown in Figure at, and includes the fiat top member or disk 20 havingdepending, from radially opposite sidest-hereof, the integral arms 21 and having attached centrally thereof and above its surface the internally threaded collar The collar 22 may or may not be an inter, al part of the disk 20,but as shown is formed of a separate metal sleeve having a reduced lower end which passes through a hole inthc lib disk and is spun over, as shown at 28,to re tainit in'thedislt. In order that the collar may not rotate within the disk when it is being screwed on to a supporting member such as the pipe .11,1there is provided the transverse strapQetintcgral with the disk 20 and over which theslots 25 oi the collar 2) fit, thus preventing any relative rotation between the two parts. The collar 22 may be provided Witlrthe set screw 26 as usual in order to prevent its accidental unscrewing from the pipell. i

Thearms Ql depend verticallyttor ashort distance from thcedgewof tlie disk 20, as shown atEE'T, and are then oi'l'setinwardly as n10 unted.

shown at 28 and continue parallelto each other to the point 29, where they converge along an arcuate curve to the point 30 where they again become parallel, but are then curved transversely in order to receive and closely engage the outer walls of the internally threaded collar and chain guide 31 which is secured to them by means of the screws 32 passing through the elongated holes 33 in the lower ends of the arms and carrying the tension spring 37, which causes the snap action and retracts the chain-after each operation. The head of this pivot is square and is slotted to receive a screw driver and is shaped to it a square aperture wlthin one of the insulation members 34, outwardly of which thereis provided the reduced opening 38 for the passage of a screw driver. It will be seen that by pressure longitudinally of this pivot, the head will be pressed out of the square apertureagainst the action of the spring 37 until it comes within the enlarged opening 39 in the insulation member when it can be rotated in order to vary the tension of the spring and thehead allowed to again come back to its Square recess in order to prcvent further rotation. The two insulation members 34 are held together near their horizontal centers by means of the screws 40 which also provide means for connecting the terminal wires. A spacer 41 maintains the lower ends of the insulation members the proper distance apart.

T he two insulation blocks 34, when fitted together, form with the switch a structure substantially rectangular in cross section, having a flat top and fiat sides with rounded corners as shown at42. The bottom of this structure is arcuate as shown at 42 following the same curve as that of the two arms 21, and the size of the whole structure is such as to snugly fit between the parallel arms 21 with the disk 20fitting against the top thereof, and with the arcuate portion42 being engaged by the curved parts of the parallel arms so that the Switch in effect floats between these arms. It may be placed inposition by sliding it between the arms from one side and is adapted to be held in this position against sliding by means of an insulating sleeve, generally denoted by the reference character 43, which sleeve is of an outside diameter substantially the same as-the diameter of the disk spring 37 as explained.

20, and which is adapted topass upward over the switch body and parallel arms 21 from below and engage against the rounded edges 42 of the switch body, and also against the under surface of the disk 20. The upper edge of the insulation sleeve is provided with four notches or slots 44, 44 and 45, 45. The rectangular notches 44 are of a width equivalent to the width of the upper ends of the arms 21 and are adapted to allow the straight portions 27 of these arms to pass through the insulation sleeve and be substantially flush with the outer surface thereof as shown in F ig ure 2. The notches 45 provide means for bringing out the wires 46 from the switch as best shown in Figure 1.

In order to retain the insulation sleeve 43 in position, there is provided the washer 51 shown in Figure 6, circular in form and of a diameter equivalent to the outside diameter of the insulation sleeve. It has in the center thereof the elongated opening 47 with the parallel sides 48. and the arcuate ends 49. This opening 47 is adapted to pass over the lower parallel ends of the arms 21 with the arcuate portions 49 engaging against their outer surfaces, and the straight sides 48 engaging against their edges. After the washer 51 is in position, the collar 31 is placed be tween the arms 21 at their lower ends and its upper surface engages against the lower surface of the washer 51 between the armssincc it is of a diameter substantially equivalent to the distance between the two curved ends 49 of the aperture in the washer, and thus serves to retain the washer in position, itself being held by the screws 32, thus completing the assembly and maintaining the whole rigidly together. The insulation sleeve 43 is provided centrally of its length and in the same plane with the notches 45 with the two holes 50 in such a position that one of them may come directly over the opening 38 in order that a screw driver may be passed therethrough to vary the tension of the operating Two of these holes are provided in order that the insulation sleeve may be symmetrical and no attention need be paid in the assembly thereof to position a hole above the screw such as would be necessary if only one were provided.

The threaded opening in the chain guide or collar 31 is adapted as previously explained to support a tube such as 16 from which the lower portion of the canopy. 12 may be sup ported, and which tube also provides an extension of the chain guide. By su porting the canopy from the tube 16, it WHITE noted that it is directly supported, then, from the pipe 11 through the interposed connecting means, including the collar 22, the disk 20, the parallel arms 21 and the chain guide or collar 31 without subjecting the switch pro er to iiny strain, incident to the weight of t e fixare.

It will of course be obvious to those skilled in the art that many other uses may be found for a switch and mounting of this type, and it is not intended that this invention shall be limited except by the scope of the attached claims.
