CONDUCTOR CLAMP AND SUPPORT.

Specification of Letters Patent. Patented Apr. 5, 1921.

Application filed October 6, 1920. Serial No. 415,192.

To all whom it may concern Be it known that I, SAMUEL S. Mnrrrrns, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Conductor Clamps and Supports, of which the following is a specification.

My invention relates to supports for conductors and particularly that type of support known as a trolley wire clamp for gripping and supporting a trolley w1re from an overhead support.

My invention has for its object a device which is simple, cheap, efficient and easy of installation and consists substantially in the construction, combination, location and arnngement of parts, all of which will be more fully hereinafter set forth, and claimed, and illustrated in the accompanying drawing in which V Figure 1 is a side elevation view of my device attached to a hanger prior to its gripping the wire.

Fig. 2 is a sectional View of Fig. 1.

, Fig. 3 is a side elevation view of my device secured to'a'hanger and trolley wire.

Fig. 4 is a sectional view of Fig. 3.

Fig. 5 is an end view in partial section. Fig. 6 is a sectional view on line 6-6 of Fig. 2.

Fig. 7 crating members. 7

F ig.- 8 is a face view of the operating member.

Fig. 9 is a sectional view of a modification of my device from that shown in Figs. 2 and 4.

The preferred embodiment ofmydnvention comprises a pair of clamping jaws 1-.1. ,A supporting member 2 is provided with means for attaching to a hanger. The means shown is a screw thread 3 which is the most. usual means employed, and which engages a depending threaded stud onthe hanger 4. r 7

The lowerend of the support member 2 provided with inwardly projecting flanges 5 forming a slot" or recess throughout the thickness of the supporting member and which is indicated by the numeral 6.1 The clamping jawsl-I are provided with outwardly projecting flanges 7 "which engage with the flanges 5 thereby preventing downward movement of the jaws relais a side elevation view of the optiyely to the supportmember 2, allowing a plvotal movement of the two jaws relatively to each other and preventing a relative rotation of the jaws and supporting member.

My device is also provided with a collar 8 which is free to rotate relatively to the other parts and the lower face is provided with a sloping surface on each side of the center line thereby providing two wedge shaped surfaces 10 which are adapted to engage a slightly raised part 11 on each jaw.

The parts are so proportioned that when the clamp has been applied to a hanger to its limit and then backed on su'fliciently to allow the entrance of a wire between the jaws 1-1 and the jaws are held in engagement with the wire, the distance B will be less than the distance A, thus assuring the forcing of the jaws to firm engagement with the wire, and the collar 14 into engagement with the hanger 4.

The support member 2 is provided with means 9 to prevent the removal of the collar 8 and the disassembly of the parts after being assembled andis produced by first making the member 9 in an upright position as indicated by the numeral 9 and after 'the parts. have been assembled as shown, the flange 9 is turned over into the position shown by the numeral 9 by means of a suitable tool- The lower edge of the jaw is provided with suitable means 12 for engaging and. gripping a trolley wire 13.v The outer surface of the collar 8 is provided with polygonal means for the application of a wrench to rotate the collar. The upper end of the collar .8 is provided with means 15 to engage the hanger 4 incase of Figs.

.2 and 4, and the supporting member 2 in case of Fig. 9. j p

In applying my device to a hanger and trolley wire the same is applied to the hanger stud as shown in Figs. 1 and 2 and by rotating the jaws which cause the support member 2 to rotate, the supporting member is drawn upwardly uponthe stud. The rotation of the device is continued until the opening between the points 12 of the jaws will just permit the insertion of the trolley wire. The jaws are now held in engagement with the trolley wire and it will be found that the distance B will be less than the distance A. A wrench is then applied to the polygonal surface of the the wedge surface 10"with a projection ll until the surface 15 of the collar engages the lower surface of the hanger 4:. When this-stageof the operation is reached, further rotation of the collar 8 in the direction of the arrow 0 will cause the jaws 11 to be moved into a strong clamping engag ment with the wire '13 and the upper face of the collar 8 into strong engagement with the lower face of the hanger, as shown in Figs. 3 and 4. v

Inthe modified form shown in Fig. 9, the device is rotated in the position on the hanger stud until the member Qis in contact or nearly so withtheface of the hanger and the jaws alined with the trolley wire. The wire is then insertedbetween the jaws and the member 8 rotated thus causing the member 8 to be raised as in the case of the construction shown in Figs. 1 and 2 and until it engages the flange on the support member 2 when its movement away from the jaws will be arrested and further rotation of the member 8 willforce the jaws lnto strong engagement with the wire.

There are many modifications which may be made in the details of construction and which will embody the principle of operation of my device and which will be evident to those-skilled in the art, and therefore I do not wish to be limited other than by the following claims:

1. A wire clamp for gripping and securing a conductor to a support eomprlsing clamping means, supporting meansand rotatable operating means having a helical face coacting with theclam'ping means to move the clamping means into engagement with the conductor when rotated.
