Claims.

My invention relates to hangers or supports for trolley wires or other conductors whereby the trolley wire may be suspended from or supported by an overhead support which may be a cable or wire spaced from the trolley wire or conductor and which is parallel to, at right angles to or obliquely disposed to the trolley wire or other conductor.

Another object or my invention is to make certain parts adjustable to permit accommodatingthe device to different relations of the supporting cable or wire to the trolley wire.

A still further object of my invention is to permit the same to be applied to the supporting cable or wire Without disassembling the parts.

My invention is provided with clamping plates or jaws between which the cable or wire or other device supporting the same is clamped, and these plates or jaws are rotatable relative to the other parts of the device and are movable laterally relative thereto within the limits of construction. These jaws or plates are also looked against relative rotation when the device is installed on the support.

My invention resides in the new and novel construction, combination and relation of the parts herein described and shown in the drawing accompanying this specification.

In the drawing:

Fig. 1 is a side view of my invention. I

Fig. 2 is another side view ofmy invention shown in Fig; 1 but rotated through 90 about the longitudinal axis x-m.

Fig. 3 is an upper face view of the lower clamping member. I

Fig. 4 is a lower face view of the upper clamping member.

Fig. 5 is a section on the line 5-5 of Fig. 3.

Fig. 6 is a section on the line 6-6 of Fig. 4.

In the preferred embodiment of my invention, I employ an insulator member I which may be of wood or molded composition or other suitable material and of such shape as will suit requirements. In the present disclosure I have shown the member I as being an elongated member having enlarged tapered heads. To the lower head is attached a cup-shaped member 2 of metal with the sides drawn into engagement with 3 is provided with an enlarged head 4 positioned within the cap 2. The stud 3, however, may be threaded'throughout its length and positioned in a threaded opening in the cap as at 5.

Also, attached to the insulator member I but in spaced relation to the cup 2 is means 6 for attaching the device to an overhead support which may be a cable or a wire or other suitable means, but which I include in the termshereinafter used as a cable or support.

The means 5 comprises an inverted cupshaped member I similar to the cup 2 and attached to the other head of the insulator member l in the same manner.

Projecting from the member I is the fixed threaded stud 8 with a head 9 positioned within the cap 'I. Mounted on the stud 8 is a nut Ill.

The end face ll of the cap! is spherical or arcuate in shape and convex, and provides a bearing surface for the clamping member I2 which is provided with a concave bearing surface to engage the bearing surface II and which is curved to correspond with that of the surface the, sides of the head thereby holding the parts inassembled relation. I v

Projecting from the member 2 is a threaded stud. 3 to which may be attached a trolley wire clamp or ear, as shown in United States Patents 1,461,752 of July 17, 1923, and 2,027,604 of January' 14, 1936,'or other suitable device. The stud The member [2 is provided with an opening l3 which is considerably larger than the stud 8 thereby offering considerable space between the side of the opening l3 and the stud 8. It wil1 be evident therefore that the jaw [2 may be rotated about the axis .r--:c and .also rocked laterally upon the surface I l in a plane common with the axis :c-.r depending upon the clearance between the stud 8 and the wall of the opening [3. This permits the hanger to be applied to overhead constructions in which the support or cable presents various angular relations to the trolley wire.

My invention is also provided with a clamping jaw or member l4 provided with an opening I5 through which extends the stud 8 which is shown in dotted lines in both Figs. 3 and 4.

In Fig. 4 the opening i5 is shown as elongated with considerable space relative to the stud 8 in one direction but considerably less clearance in the other direction thus permitting considerable lateral adjustment in one direction normal to the axis x-::: but quite limited lateral adjustment in the other direction.

The clamping members I! and M are provided with grooves 16 and I1 respectively and which cooperate to form the opening is constituting a transversely disposed gripping seat adopted to receive cable or other support.

The clamping members l2 and M are spaced somewhat apart which permits drawing them into clamping relation with the cable or support which may vary in diameter within limits.

The clamping member I2 is provided at one point, preferably opposite the groove It with an upwardly projecting lug l9 and the clamping member I4 is provided with spaced lugs projecting downwardly and placed opposite the groove l1 and between which lugs 20 the lug l9 is positioned. UEitherthe lugs 20 or the lug l9 or both may engage the adjacent surface of the cooperating jaw and act as a fulcrum or pivot 1 when the clamping members are brought into engagement with the cable or other support.

The described interlocking of the lugs lt and 2t prevent relative rotation of the members "I12,

and 14 without checking their relative lateral movements. Such rotation is also prevented by the clamping of the members the cable. Y

The axis y-y of the opening i8 is spaced a considerable distance from the axis x::: and from the disclosure it will be apparent that. this axis may take varying angular positions about the axis arr-32 sinceit is rotatable-about the axis :cx in a plane at right angles thereto and also the lateral movement of the jaws may change to a small extent the spacing between the axes and y-y.

By the use of' the term lateral orlaterally in the appended claims, vI mean a movement normal to the axis :ta:; as in the case of jaw 14 and 12 and JA -upon by rocked or -roclnng" I refer to a movement of the jaw [2 relative to the axis at--92 due to the curved or hearing faces on the cap 1 and jaw 12, and by rotate or rotatably- I refer to the rotation of the jaws about the axis r-a: as in a plane normal to the axis.

My invention may be installed by first attaching the trolley wire clamp orear to the trolley wire and then rotating the stud 3 into position with respect to the clamp or ear, or the clamp or ear may be first attached to the stud 3 and thentothe trolley'wire.

The nut lll is then rotated to loosen the jaws i2 and [4 relative to each other to permit them to open sufficiently toreceive the cable-or other support within the opening 18, the jaws being adjustable relative to the cap 1 while the jaws areibeing positi'onedupon the support.

If the cableor other support to be :clampedjn the opening 18 is considerably larger .in diam eter than that of the opening it, the spherical surface on the members LT and I 2 will permit the member 12 to adjust-its position spherically with respect to the :cap 1 and :the jaw 14 and axis zit-:1: whereby the jaws will open farther on the groove side to accommodate the larger cable. The flat bearing faces in engagement between the jaw I4 and the washer 2i or out iii holds the jaws l'4 normal to the axis :c-a: when the jaws are tightened upon a. cable, thus forcing the jaw l2 to adjust itself tomeet the requirements.

The nut It is then rotatedinto clamping :position and the interposed spring "washer 21 will prevent the backrotation of the nut in.

The stud 8 and nut l0 may have substituted therefor a so-called cap screw in'which the nut is a fixed part of the threaded stud and in this case the upper end of the cap 1 will be threaded to receive the threaded end of the cap screw. The result in this case is the same as with the use of the stud 8 and the nut HI.

It is usual to position the hanger so that the axis a:::: will be vertical or substantially so, but the device "may" be used in any other position as,

for instance, in a substantially horizontal position as when used as a strain member.

The offset groove l8 spaced from the axis 02-4: avoids the necessity of removing the nut l0 and the jaw M from the device in order to position it on the supporting cable as would be the case if the axis y-,y intersected the axis a::r.

Modifications will suggest themselves to those skilled in the art and, therefore, I wish to be limited only by my claims.
