Abstract

A multipurpose pole line clamp for clamping utility cables and for supporting service drops. The clamp comprises a bearing member and a clamp member. The bearing member is provided with a tapped hole engaging a throughbolt extending through the utility pole. The clamp member is provided with an enlarged through hole to facilitate clamping it on the throughbolt with ease of assembly. Facing surfaces of the bearing and clamp members cooperate to anchor a messenger cable. The bearing member includes a saddle-horn-shaped stanchion for transferring to the pole the tensile load of a secondary messenger cable supporting the service drop line.

Claims

1. A multipurpose clamp for anchoring a utility line messenger cable to a utility pole and for deadending a service drop messenger cable simultaneously, comprising:

A. a bearing member adapted to abut against a utility pole and comprising;

1. a hub portion having a horizontal throughbolt receiving passage therethrough, 2. a top surface upwardly spaced from said passage, 3. a forward bearing surface to which the forward end of said passage opens, having a first messenger cable-receiving groove spaced below the forward end of said passage, 4. a rearward pole-engaging surface to which the rearward end of said passage opens and including upper and lower poleengaging pad means respectively spaced above and below the rearward end of said passage, and 5. an upright stanchion integrally supported on said top surface in forwardly spaced relation to said rearward poleengaging surface and rising above the horizontal plane of said upper pad means, and having a second messenger cable loopreceiving saddle-shaped groove extending about its rearward face along opposite sides to its forward face;

B. a clamp member including an upper fulcrum portion for fulcrum engagement with said forward surface of said bearing member above the forward end of said passage and having a messenger receiving groove for facing juxtaposition with said first messenger cable-receiving groove of said bearing member; and

C. clamping means for anchoring the clamp member and the bearing member together against the utility pole.

2. The clamp as defined in claim 1, wherein the clamping means includes:

A. said throughbolt receiving passage forming a first throughbolt hole, extending poleward through the bearing member;

B. means forming a second throughbolt hole extending poleward through the clamp member;

C. a throughbolt extending through the utility pole and the first and second bolt holes; and

D. nut means cooperating with the throughbolt to draw the bearing member and the clamp member together.

3. The clamp as defined in claim 1, wherein the bearing member pad means further includes prong means to be imbedded in the utility pole.

4. a rearward pole-engaging surface to which the rearward end of said passage opens and including upper and lower pole-engaging pad means respectively spaced above and below the rearward end of said passage, and

5. The clamp defined in claim 2, wherein the second throughbolt hole is larger than the diameter of the throughbolt to facilitate rocking pivoting manipulation of the clamp member for installation of the first messenger cable.

6. The clamp defined in claim 2, wherein the first throughbolt hole is sufficiently larger than the diameter of the throughbolt to permit rocking embedment of the bearing member under loads applied in directions away from the pole by the second messenger cable to the stanchion.

7. The clamp defined in claim 1, wherein the bearing member is provided with messenger supporting finger means protruding therefrom beneath the first messenger cable-receiving groove in a direction away from the pole surface, providing temporary messenger support during manipulation of the clamp assembly.
