Application filed June 26,

My invention relates to supporting devices for conductors and has particular reference to trolley and feeder conductors in mines.

One object of my invention'is to providea device which will support not only the trolley conductor but the feeder conductor therefor and in which the device will act as an equalizer between the two conductors. Another object is to provide a device with clamping arrangement ,which will accommodate a wide range of feeder conductors aswell as a considerable range of trolley conductors thus economizingin the number of devices a mine would be obliged to Lcarry to meet its requirements. Another object Visto providea device with clamping mechanism for the conductors which will open by gravity and therefore does not requireholding the clamping mechanisms open while installing the conductors. A still further object is to remove the feeder conductor away from the trolley conductores far as possible withinreason, thereby lessening the chances'of the flying.` trolley pole becoming entangled with the conductors.

My invention resides in the new and novel construction, combination and relation of the various parts hereinafter described and shown in the drawing.

Fig. 2 is a top plan view of' my invention shown in Fig; 1; y A

In the preferred embodiment ofmy invention I employ a socket 1 internally'threaded as indicated at 2rto receive a hanger or other supporting device. Projecting laterally and at right angles to the axis of the socket 1 is a straight arm 3 havingr at the free end a tubular portion 4 which has a passage therethrough comprising a part 5 of less diameter than the part 6; Projecting inwardly at the lower end of the member' 4 is an annular flange 7.v j L Mounted within the tubular member 5 and projecting from both ends thereof isc lamping mechanism comprising a pair of jawsS having co-operating li'ps 9 to receive and grip a trolley vwire 10. The jaws are hinged together by means of a pintle 11 and secured to 1930. ySerial No. 463,915.

the pintleH1-1 is a threaded stud '1Q-having i mountedgthereon the threaded nut 13 engaging the upper endLofthe member 4.V It .will

be noted that-the mechanism comprising the parts 8, 11 Yand 12 arel quite freetomove axially or up and-down within thetubular member 4 and that the downward movement of the Vsaid parts are limited bythe nut The downward movement of the parts is due togravity. j mf The upper end ofthe jaws Sat thirouter edges are Yeach providedl with anfarcuate groove 14which receives the annular flange 7. Thejaws and stud 1 2 are `free to Yrotate about their vertical axiswithinjthe member 4, but the interlock betweenthe jaws and theflange 7 will cause the jaws to fulcrum with respect to the'ange 7 such that as the nut 13 is moved upwardly on the stud 12 and -withone hand to place the trolleywire 10 in position betweenrthe awsA andwith the other V hand to rotate the nut 13 to cause: it tomove downwardly relative to the stud 12 thus drawing thefstu'd 12 upwardy and with it the hlngeipoint of the jaws thus causing the jaws to fulcrum about the flange 7 andffor'cing'the ylower end. of the jaws together and with gripping engagement with the'iconductor 10.

A wrench may then beV applied to the nut' V'13l which will make the grippositive. Also projecting'from the socket 1 there is a l downwardly and outwardly formedy arm 15a'nd`having an integrally formed :jaw 16Y having agroove 171to receive the conductor 18; y `Pivotally securedfto the'free endof the arm 15 by Vmeans of the pin'19 isa movable jaw 2O so constructed that if unrestrained its free end will move awayrfrom'A lthe`jaw'16 by gravity. Thejaw 20 isprovided witha groovef21preferably V shaped.. The 'movement of the jaw 2O relativeto the jaw 16 is controlledby means of the bolt and nut 22 esY disposed in transverse openings 23 and 24: of the awsV 16 andQO respectively.

The free end of the arm l5 is in a horizontal plane below, but parallel to a horizontal plane of the arm 3 and the conductor l8`is positioned in a horizontal plane parallel to that of the plane ofthe arm 3, but above the same and also above a horizontal plane of the conductor 10. .Y

VThere will be modificationsPwhch will suggestthemselves to those skilled in the art after reading my disclosure and therefore l wish to be limited. only by my claims.
