Abstract
Abstract A support rack for mounting at least one electrical current transformer upon an electrical utility pole, including a bracket for each current transformer, a hollow arm connecting each bracket to a hollow junction box having a depending conduit connection to an electrical meter mounted on the same pole, so that one set of wires from the current transformers are led through the arms and the junctions box to the meter at a substantially lower secondary voltage than the secondary wires leading from the current transformers to the customer service lines.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
A support rack for mounting at least one transformer upon an electrical utility pole comprising: (a) a pole bracket adapted to be mounted upon a utility pole, (b) a hollow junction box having side walls and a bottom wall, said junction box being fixed to said pole bracket, (c) a horizontal conductor opening through one of said side walls, (d) an elongated hollow arm having open proximate and remote ends, (e) said proximate end being received within said horizontal opening, (f) a transformer support bracket, (g) means fixing said transformer support bracket upon the remote end portion of said arm so that said remote end remains open, (h) a meter wire opening in the bottom wall of said junction box, (i) said arm and said junction box receiving at least one electrical conductor wire from a transformer mounted on said transformer support bracket and extending through said arm, said junction box and down through said meter wire opening to a meter mounted on said utility pole.
Claim 2
Dependent Claim
166 words
A support rack for mounting at least one transformer upon an electrical utility pole comprising: (a) a pole bracket adapted to be mounted upon a utility pole, (b) a hollow junction box having side walls and a bottom wall, said junction box being fixed to said pole bracket, (c) a horizontal conductor opening through one of said side walls, (d) an elongated hollow arm having open proximate and remote ends, (e) said proximate end being received within said horizontal opening, (f) a transformer support bracket, (g) means fixing said transformer support bracket upon the remote end portion of said arm so that said remote end remains open, (h) a meter wire opening in the bottom wall of said junction box, (i) said arm and said junction box receiving at least one electrical conductor wire from a transformer mounted on said transformer support bracket and extending through said arm, said junction box and down through said meter wire opening to a meter mounted on said utility pole.
Claim 3
Dependent Claim
51 words
The invention according to claim 1 in which said junction box has at least three side walls, at least one horizontal opening through each of said side walls, at least one elongated hollow arm, and a closure plug for each horizontal opening not receiving the proximate end of a hollow arm.
Claim 4
Dependent Claim
65 words
The invention according to claim 2 wherein said junction box has three side walls disposed at angles to each other, a horizontal opening in each side wall and said arm supporting said transformer in a single-phase, alternating current, power transmission system, the proximate end of said bar being received in one of said horizontal openings, and two closure plugs closing the other two horizontal openings.
Claim 5
Dependent Claim
75 words
The invention according to claim 2 wherein said junction box has three side walls at angles to each other, one horizontal opening in each of said side walls, and three arms including said first arm, the proximate end of each being received in each of said horizontal openings, and said transformer support bracket fixed on the remote end of each of said arms for receiving three transformers in a three-phase, alternating current, power transmission system.
Claim 6
Dependent Claim
52 words
The invention according to claim 1 further comprising a connector depending from said meter wire opening, a meter wire conduit having upper and lower ends, the upper end of said conduit being connected to said connector, and the lower end of said conduit being adapted to be connected to said electrical meter.
Claim 7
Dependent Claim
82 words
The invention according to claim 4 in which each of said transformer support brackets comprises a sleeve block adapted to be slip-fitted over the remote end portion of each of said arms, and means for detachably securing said sleeve block to said corresponding arm, each of said transformer support brackets further comprising a transformer support plate, and means connecting said sleeve block to said transformer support plate and spacing said transformer support plate outwardly from the open remote end of said arm.
Claim 8
Dependent Claim
52 words
The invention according to claim 1 further comprising an open sleeve boss projecting outwardly and coaxially of said horizontal opening and having an inner cross-section substantially equal to the outer cross-section of the proximate end portion of said arm for receiving the proximate end portion of said arm within said sleeve boss.
Claim 9
Dependent Claim
20 words
The invention according to claim 1 in which said arm comprises a straight, elongated tubular member of electrical insulating material.
