To @ZZ whom t may conce/Mt:

Be it known that L HOHER P. CHANDLER, acitizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have inventedV certain new and useful improvements in Conductor Supports, of which the following is a. specication.- l

My invention relates to conductor supports and more, particularly to that class of support for securing a trolley wire to an overhead hanger.

@ne of the objects of my invention is to produce a device which can be secured to a hanger, and then. .have the jaws which grip the trolley wire aline with the trolley wire without disturbing the relation between the clamp and the hanger, and then to move the jaws into gripping engagement with the trolley wire. Another object of my invention is to produce a device in Vwhich the jaws can lbe alined with respect to the hanger, and in which the jaws can ybe positively moved into or out of engagement with the trolley wire. Other objects will be disclosed to those skilled in the artv 'from the description herein of my preferred form of construction.

My invention resides in the new and novel construction, combination and relation of the various elements of which the invention is composed as herein described and shown in the accompanying drawing.

ln the accompanying drawing: j

Fig. 1 is a side view in elevation of my complete invention shown as engaging a trolley wire.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a sectional view of my invention taken on the line 3-3 of Fig. 1, showing a hanger in combination therewith and the jaws open to receive the trolley wire. n

Fig. 4 is similar to Fig. 3 excepting the jaws are shown in gripping engagement with the trolley wire.

Fig. 5 is a sectional view on the line' 5 of Fig. 4, and shows means'whereby two of the elements have a limited relative rotation with respect to each other.

In the preferred embodiment of my in- 1923. Serial No. 635,872.

member 4 is provided with an internallyy projecting flange 5 which engages and rests upon the flange 3 and is supported thereby.

Erice. A

YThe thickness of the flange 5 is preferably slightly less than the distance from the upper face of thevfiange 3 to the upper face of the supporting member` 1, so that when the device is installed upon the hanger H i the operating member 4 will not bind, butwill be free to rotate relative to the supporting member 1. The operating member 4 is provided with an internally threaded supporting member 1 is provided with a projecting lug 9 which engages with a. projecting lug 10 on the intermediate member 7. lt will be seenfrom Fig. 5 lthat the members 1 and 7 are free to rotate relativeto i; each other, but have the said rotation lim- I ited by the engagement of the lugs 9.and lOl Projecting from the lower end of the member 7 is a lug 11 provided with an opening to receive the pin 12. Securedto the lug 11 are two 'jaw members 13 provided with means 14 at their lowerends to engage a trolley wire 15. rAdjacent the upper end of the jaws 13 vand projecting inwardly are lugs'16, and held in position with respect to the lug 11 by means of the pin 12 whereby the jaws are permittedY to swing' about the axis of the pin 12, but cannot rotate votherwise with respect to the lug 11.

The jaws 13 are each provided near its upper end with an annular groove 17 formedfby the adjacent anges 18 and 19,

Y and said groove may extend lentirely around kthe circumference of each jaw 13 or only part way around, depending upon the eX- tent of the flanges 18 and 19. Positioned within the groove 17 of eachpjaw 13 is a flange 2O projecting from the lower portion of the operating member 4. The flange 20 engages the flange 19 to move the jaws' 13 into kengagement with the trolley wire and to hold them in said engagement. The flange 2O engages the flange 18 tomove vention lY employ a supporting member 1 :the jaws out of engagement with the trolley internally threaded to engage the threads on a stud 2 of the hanger H. kThe supportl ing member 1 is provided with a flange 3 to support an operating member 4. The' wire or to open them to receive the trolley wire and to maintain the jaws in an open position. The jaws 13 and the operating' member 4y are free to rotate relative toeach i other. member yis provided with a heldagainst a longitudinal movement with respect to the member 1, but the member 7 can move longitudinally with respect to the member 1 when the member l is rotated in either direction. It will also be observed that there is substantiallyno relative longitudinal movement of the member d with respectto the upper outer portions of the jaws 13 other than a pivotal action therebetween, andsthat the lugs 16 move with' the member The `operation of installing my invention` upon the hanger consists in first grasping the jaws lipreierably with the hands and in placing the member 1 in engagement with thestud 2 of the liangerfH. -the aws are now rotated in tlieproper direction the lug 10 will be brought into engagement with the' lug ,9, and when this rengagement taires place further rotation oir the jaws will rotate the member 1 intofull and secure engagement witlithe stud 2 until the upper face oiC the member-1 engages the -lower face of the hanger i After this operation the jaws 18 may not be in alinement with the trolley wire, but `this, alinement' can be brought about byreversing the direction ot rotation of the jawsand this reversal of rotation will not rotate the member 1, as the amount of back rotationl would not-exceed 186 degrees andthere is a possible relative rotation of the vmembers 1 and 7 ot less than 360 degrees, dependin vupon the thickness ofthe lugs 9 and 10. lavi-ng alined the jaws with respect tothe trolley wire, it the jaws are in a closed position so as not toreceive the trolley wire, the operating member eiis rotated in a proper direction to cause the member 7 to move downwardly due to the threaded engagement, and this will cause the jaws to pivot about their pointotengage- A. ment with the operating member and thereby force the jawsvto. open. Having opened the awskthe trolley wire is placedV in position between the jaws, and the operatingmember is then rotated lin a direction to cause the member 7 to move upwardly A'until the aws engage the trolley wire. wrench is now applied to the -faces 21 ofthe operating member #l and further rotation or the member t by means of the wrench will force theaj aws into further and secure engagement with the trolley wire.

ln Fig., 5 the lugs 9 and 1() are shown in separated, is illustrative or a position which the lugs may take after the jaws have been alined with respect to the trolley wire.

Modiiications will occur to those skilled in the art from .the disclosure which l have herein made, but l do not wish to be limited other than by my claims.
