Application filed November 2 To all whom it may, concern:

Be it known that I, HOMER P. CHANDLER, a citizen of the United States of America, residing at Mansfield, in the county of Richlandand State of Ohio, have invented certain new and useful Improvements in Conductor Supports, of which the following 1S nation of the various parts hereinafter more fully described and disclosed in the drawing, forming a part of this application.

In the drawing Figure 1 shows a side elevation of a device embodying my invention as secured to a trolley wire.

Fig. 2 shows an end elevation of Fig. 1.

Fig. 3 shows a sectional view of Fig. 1 on the line 38.

Fig. 4 shows a longitudinal. view in section of Fig. 2 on the line 4.

Fig. 5 shows a transverse sectional view with the jaws opened up in positionto grip a trolley wire.

In the preferred form of device embody.- ing my'invention I employ a support memher 1 provided with a threaded recess 2 by means of which the device is detachably secured to an overhead support. Depending from the support member 1 is a lug 3 provided with a channel 4. Secured to the lug 3 by means of a pin 5 are two jaw members 6 which are duplicates and each of which is provided with two lugs 77 and 7-7 respectively. It will be noted thatthe lugs are fixedly pivoted to the supportingmember 1 so that the lower ends of the jaws which are provided with lips 8 for gripping the trolley wire are free to move toward and away from each other. Each. jawis provided with a pro ecting arcuate shoulder 1 havin a beveled upper surface 10. Mount 7, @532. Serial No. 603,449.

the outer edge of the shoulder9 on each aw. It Will be noted that the angles of faces The lower endotf the operating 10 and 13 are made quite difierent. and I have purposely. done this so that with the varying;- sizes oi -wlre with which my device used, the two faceswill not at any timev contact throughout, but the eontact between the shoulder 9 and the operating member 11 will be always at the outer edge of the shoulder 9, and I prefer to have the point of contact between the shoulder Qand the operating member 11, when the jaws. are in engagement with the trolley wire, below the axis. of the pin 5, and so dimension my de. vice that w th the various sizes of wire with which it will be used the point of contact between the shoulder-9 and the operating member ,11 will be below the axis of the pin 5 as indicated at A. 1

At the upper end of the operating member 11 I provide a flange 14 to engage with a flange 15 on the supporting'member 1.

The flange 14.- is originally in upright position so that the face 16 ofthe operatlng member can be brought into contact with the lower face of the flange 15 when the op-.

erating member is screwed upwardly a suff cient distance. adapted to be turned inwardly as shown in the various figures in the drawing after the device has been assembled to prevent disassembling as later explained. i To assemble the aforesaid described. device, I first assemble the support and operating members 1 and 11 and bring the shoulder 16 into engagement with the lower race of The operat ng member 113 the shoulder 15. 18 so proportioned that its'lower edge when aositioned on the sunortino member as just described, will not extendbelow the upper edge of the channel 4 in the support} ingr member. With theoperating member and supporting member assembled as described, the two jaws 6-6 are placed in position with respect to the lug 3 and channel 4 and the pin 5 inserted into position thereby pivotally and fixedly mounting the jaws in relation to the supporting member. The operating member is then screwed clown- The fiangel l, however, is

ward until the upper edge of the member 1% clears the lower face of the flange 15 and then the upstanding member let is turned inupper edge of the pin 5 and the lower petticioat f'the operating member 11 will overlapthc pin 5 for a distance indicated by B fitment could be eliminated and the ends oftne pin 5 riveted over which would serve to loclz'the parts permanently together, but

lprefer to use'the flange it as just described or'equivalent means, v

a lin jassembling my device upon support and trolley wire the clamp is first screwed on tothe stud of an overhead hanger H by means 01? the then the lips 8 of the jaws G are brought into alinement with the trolley. wire. The jaws are then openedup at the lower end and thetrolley wire inserted in position and the aws allowed to fallback until the lips 8 en gage thetrolley wire. The jaws are now held in position in engagement with t 1e trolley wire and the operating member 11 rotated preferably by hand until it engages with the shoulder 9 on the jaws, thereby ioldingzfthejawsin position in engagement upon tbetrolleywire. This engagement can now he made/more secure by applying awrench to i the polygonal faces 17 of the operating: membetween the parts islzept low and'coz.

parts b'eritl erehy still furt er rotating the operating member into engagement with the 6', which in turn forces the lips 8 into stronger engagement with the trolley wire.

The advantage of having the contacting point between elements 9 and 13 on a line i or preferably below the ariis of the pin 5 or'other pivotal point, is that the friction fined almost exclusively to that due'to the parts rotating: together, If the contact point is above the an sor" the pin 5,or other piyotal point as the jaws pivot about the pin '5, the contact edge of the member 9 will tend to move outward towards the surface thereby bringing anadditional friction upon the If the surfaces l0 and 13 should coincide througl'iout their height, and since the size or" trolley wireyariea there is a probability that the engagement between the members 6 I and 11 may vary as for instance the contact thread 2 as tar as possible and of 6 with 11 may be at times as shown in the drawings, at other times it may be throughout the surface 10 and at other times it may be with the edgelS. By my proposed construction the contact is kept practically uniform and constant.

have shown the hanger H in Fig. l only but "ts attachment to the clamp does not in a iy'atlect the operation of the clamp as anger acts merely as a support and the clamp may be secured to the conductor prior to being secured to the hanger H if desired.

Having described my invention as required,
