'3 Claims.

This invention relates to certain new and useful improvements in conductor and ground wire supports, and has as an object the provision of an improved device wherein longitudinal movement of the conductor is accommodated without disrupting or in any wise interfering with the support.

Another object of this invention resides in the provision of an improved support of the character described which permits the connection of a conductor therewith without necessitating dismantling of the support and without requiring the cutting of the conductor.

And a further object of this invention resides in the provision of an improved support of the character described having a .high conductivity connection between the conductor and the ground wire running down the pole.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope'of the claims.

In the accompanying drawings, I have illustrated two complete examples of the physical 39 embodiment of my invention constructed according to the best modes I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a front plan view of an improved conductor support or clamp of the flexible type embodying my invention;

Figure 2 is a view, partly in side elevation and partly in section, taken through Figure 1 on the plane of the line 2-2;

. Figure 3 is a perspective view of the conductor support; and

Figure 4 is a perspective view of a slightly modified clamp embodying this invention.

Referring now more particularly to the accompanying drawings, in which like numerals designate like parts throughout the several views, 5 designates a pole or other support, shown in the present instance as of metal construction, adapted to have a U-bolt 6, having a loop '7 in its lower outer end portion, secured thereto by clamping nuts 8 engaging opposite sides of the support. A link 9 is engaged in the loop or recess andpiv- ,otally supports a conductor clamp device 10.

The clamp device consists of a lower member 11 and an upper member 12, the lower member being of substantially approximately U-shape with the ends or lips 13 of its trough or channel jacent ears 15 and 16 force the lower longitudinal edge portion 18 of the top member against the conductor to secure it within the channel 19 of the member 11, the edge of the upper member engageable with the conductor being grooved, as illustrated in Figure 2, to insure a firm clamping action.

The inclination of the bores in the lugs 15 and 16, as illustrated in Figure 2, insures the movement of the edge 18 of the upper member into the channel or trough 19 of the lower member as the bolts 1'7 are tightened. This construction, as will be evident, permits a universal movement on the part of the conductor to thus eliminate its crystallization by movement of the conductor at the point of entrance between the clamps and allows longitudinal movement of the conductor within a limited range.

The clamp proper is suspended from the link 9 by a hook 20 formed on the upper member between its lugs 16 and which engages in the link, as best illustrated in Figure 2, this arrangement causing the clamp to spread of its own accord as the bolts 17 are loosened to facilitate the insertion or removal of the conductor as will be evident. Disengagement of the hook from the link 9 is prevented after the bolts 17 have been drawn tight, by the restriction of the space between the outer portion of the hook 20 and the medial portion 11 of the lower clamping member, see Figure 2.

A ground conductor 21 may be connected with the main conductor 14 by a lead 22 secured in electrical engagement with the clamp by one of the bolts 1'7 and with a terminal 23 by one of the clamping nuts 8 between which and the support 5 the terminal is secured, the ground wire bei ng electrically connected with the terminal. In that form of my invention illustrated in Figure 4, a rigid type of support is illustrated in which a lug or ear 24 is formed on one of the clamp members to provide means for securing the support to the pole 5 by means of a bolt 25, the ground wire 21 being connected thereto by a terminal similar to terminal 23 confined between the inner surfaces of the pole 5 and the nut threaded on the bolt 25.

From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art to which an invention of the character described pertains, that I have provided an improved conductor and ground wire support which will facilitate the mounting of a conductor and which will accommodate the movements of the conductor due to the contraction and expansion and "which will insure the highest possible conductivity between the conductor and ground wire.

What I claim as my invention is:

1. A device of the character described, comprising a support, a freely movable supporting member carried thereby, a clamp, means connecting the clamp with the freely movable supporting member, a conductor wire secured in the clamp, a ground wire engageable with said support, and a flexible conductor electrically connectigg the conductor wire with the support.

2. device of the character described, comprising a support an elongated channel member adapted to receive a conductor wire in said channel, a clamping member carried by said support, means for drawing the clamping member toward the channelled member to impinge the conductor wire therebetween, a ground wire clamped under said support, and flexible means electrically connecting the conductor wire with said support.

3.
