Abstract
Abstract A mounting system for an additional communication cable on a utility pole is described. This mounting system includes a support arm which bolts to a through bolt that extends through the utility pole and is used to mount a pre-existing communication cable. A strand clamp is mounted to the outer end of the support arm, and the strand clamp serves to support a strand and a communication cable such as a CATV cable in the conventional manner. If desired, a diagonal reinforcing strap can be provided between the pole and the support arm. By using a single through bolt to mount both the strand clamp for the existing communication cable and the support arm, clearance and interference problems are minimized and installation costs are reduced.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
In combination with a cable support pole of the type comprising a fastener extending through the pole, a first strand clamp mounted by the fastener to the pole, and a first communication cable supporting strand secured by the first strand clamp, the improvement comprising: a one-piece, integral support bar comprising a central horizontal leg, an inner vertical leg secured at one end of the horizontal leg, and an outer vertical leg secured at the other end of the horizontal leg, said inner vertical leg defining a first horizontally oriented opening sized to receive the fastener such that the inner vertical leg is secured to the pole by the fastener and the horizontal leg extends substantially no higher than the first strand clamp, said outer vertical leg defining a second horizontally oriented opening; a second strand clamp comprising a fastener passing through the second horizontally oriented opening to secure the second strand clamp to the outer vertical leg at a point laterally spaced from and below the first strand clamp, said second strand clamp adapted to secure a second communication cable supporting strand in place laterally spaced from and below the first communication cable supporting strand.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
58 words
The invention of claim 1 further comprising a brace having an upper end secured to the pole at a point above the fastener and a lower end secured to the outer vertical leg, said brace extending diagonally between the pole and the support bar to support the support bar against downward loads applied to the second strand clamp.
Claim 4
Dependent Claim
36 words
The invention of claim 1 wherein the support bar is dimensioned such that the vertical separation between the first and second strands is substantially as great as the lateral separation between the first and second strands.
