To all w tomc't mayy concern.'

Be it known that'l, Hoarau P. CHANDLER, a citizen kot the United States of America, residing at Mansfield, kin the county of Bichland and State of Ohio, have invented Cei" tain new and usei'ul Improvements in Con` ductor Supports, of which the following is a specilication.

My invention relates to conductor supports and lmore particularly to that class oi' supports for securing a trolley conductor or wire to an overhead hanger.

One oftheobjects oi' my invention is to produce a device which can be secured to an overhead hangerv and in which the jaws can be moved either into or out of engagement with the trolley wire to grip or releasethe same as desired.

Another object of my invention is to produce a. deviceY in which the jaws. mayV be moved into alinelnent with the conductor after the device has been secured to an overhead hanger.

Another object of my invention isto pro duce a device in which the aws are free to rotate without limit after the device has been installed upon a hanger.

Another object of my invention is to produce a device in which the jaws are movable toward and away from the hanger before and after the jaws engagewith the trolley wire in order to assist in the installation ot the device upon. the hanger prior to the jaws gripping the trolley wire andpto permit vertical movement of the trolley wire relative vto the hanger under action ot the upward pressure of the trolley wheel, all as later herein described. y

My invention resides in the new and novel construction, combination and. relation of the various parts hereinafter more fully described and disclosed in the drawing accompanying this specification.

in the drawing:

Fig. 1 shows a side view in elevation of my invention as secured to a trolley wire.

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

Fig. 3 is a transverse view in section of Fig. 1 taken .on the line 3-3 and also shown as secured in position on an overhead hang- Fig. 4 is a longitudinal section taken on the line Ll--Ll of Fig. 2.

Fig. 5 is a sectional view corresponding to Fig. 3, but with the aws opened to receive the-trolley wire.

Fig. 6 is a transverse sectional view snowing the engagement of certain parts: employed in securing a device to the overhead hanger.

Fig. 7 is a sectional view on the line 7-7 ot Fig. 3.

ln the preferred construction embodying my invention, i employ a supporting member 1 internally threaded to receive the threaded stud S ot the overhead hanger H. The member 1 is provided with an outwardly extending flange 2 and the flange 2 is provided with a stop lug 3. Mounted upon the supporting member 1 is an operating member 4l which is supported bythe sup porting member 1 through the inwardly projecting lange 5 engaging the iiange 2.' 'lhe operating member l is provided with an in ternally threaded port-ion 6. Threadably engaging the portion 6 is an intermediate member provided with the threads S engaging with the threads on the operating member. rihe intermediate member is provided with a slot 9 adapted to engage with the lug 3, but normally held out oi engagement with the lug 3 by the interposed spring 10. rl`he member 1 is normally ree to rotate relative to the operating member l and to the intermediate member 7, but when the lug 3 engages with the slot 9 theV parts 1 and 7 are interlocked and when either part is rotated the other part must rotate simultaneously and in the same direction. There is no interlocking, however, between the member 1 and the member 4.

Projecting from the lower end of the member 7 is a lug 11 provided with an opening to receive the pin 12. Secured to the lug 11 and in; pivotal relation thereto byY means oi' the pin 12 are two jaw members 13 provided with lips 1a at their lower edge to engage a trolley wire 15. The jaws are mounted on the pin 12 by means of the inwardly projecting lugs 16 arranged in pairs on each jaw and they alternate with the lugs on the opposite jaw, as shown in Fig. 7.

The upper end ot-the jaws 13 are each provided with an annular flange 17 of considerable extent and a much shorter flange 1S forming a groove or channel 19v there-V between. Positioned within the groove or channel 19 of each jaw is an annulariiange projecting from the lower portion of the operating member 4. The flange 2O engages the flange 17 to move the jaws 13 into engagement with the trolley wire and to hold them in such engagement. The flange 2O engages the lange 18 on each jaw to move the jaws out of engagement with the trolley wire or to open the jaws to receive the trolley wire and maintains the jaws in an open position. The operating member 4 is :tree to rotate relative to thejaws and is provided with a plurality of faces 21 to receive a wrench or other tool whereby the member 4 may be rotated.

It will be noted that if the operating member 4 is rotated relative to the jaws 13,

, that the operating member will move along the longitudinal axis of the device in a direction toward or away from the jaws, depending upon the direction of rotation, and that if the member 4 is so rotated as to move toward the jaws, that the jaws will be moved into a gripping engagement with the trolley wire 15, but it Vthe member 4 is rotated so as to move away from the jaws 13 that the jaws will be moved further apart at their lower edge or out ot gripping engagement with the trolley wire, and that regardless of how the jaws may be moved, they will be maintained in an opened or closed position through their interlock with the member 4.

It will also be observed that if the intermediate member 7 is brought into interlocking relation with the supporting member 1 through the lug 3 engaging with the slot 9, that the member 1 will be caused to rotate in unison with any rotation ot the parts 13.

It will also be evident that when the device is installed on a hanger, as shown in Fig. 3, that upward pressure upon the trolley wire in excess of the tension in the spring l0, will cause the trolley wire to be raised. This action is found to be of considerable beneit, as it prevents what is termed, hard spots, in the trolley construction where the trolley wire is rigidly supported, and such vhard spots tend to cause a rebound of the trolley wheel and consequent arcing. If the trolley wire is permitted to rise and fall with the passage of the trolley wheel at the point ot the support, the rebound of the wheel is either eliminated wholly or to a large degree with consequent elimination of arcing.

It will be evident that having installed Y the device upon an overhead hanger, that the jaws are free to be rotated Vinto alinement with the trolleywire, and having been positioned in alinement with the trolley wire, that rotation of the operating member 4 in the right direction will move the jaws into gripping engagement with the trolley wire. j

In installing my improved cla-mp the end of the member 1 is positioned against kthe end of the member S and the jaws and operating member are then pressed upwardly thereby compressing the spring 10 and then rotated until the lug 3 engages with the slot 9. (See Fig. 6.) Continued rotation of the jaws 13 will cause all parts to rotate in unison and the member 1 will be moved upwardly upon the stud S until it engages the lower face of the hanger H. The upward pressure upon the jaws 13 is then removed and the spring 10 will cause the members to return to their normal position, as shown in Fig. 5. The device is now installed upon the hanger H and the parts are free to rotate relative to the hanger. The jaws are now rotated into alinement with the trolley wire and it the jaws are not suiiiciently open to receive the trolley wire, the operating member 4 is rotated in the proper direction thereby moving the jaws to a more open position. The trolley wire is then inserted between the lips 14 of the jaws, as shown in Fig. 5, and the operating member 4 is rotated in the proper direction to move the intermediate member 7 upwardly or toward the hanger, the jaws being prevented from rotation by the insertion of the trolley wire 15 therebetween. This will move the jaws into engagement with the trolley wire 15 and a further gripping action can be secured by applying a wrench to the faces 21 ot' the operating member 4. The relation oi" the parts when installed is shown in section in Fig. 3.

It will be evident that in order to remove the trolley wire from the clamp and the clamp from the hanger, that the operations just described should be reversed.

Modiiications froml the single preferred embodiment ot my invention, as herein disclosed, will be evident to those skilled in the art and other objects and uses no doubt `will disclose themselves to others, all of which Vwill fall within the scope of my invention.
