Abstract
Abstract Resin coated, preservative impregnated wooden poles having one or more longitudinal kerfs, for stress relieving and ventilation purposes, at least one kerf being cut to a depth slightly greater than the thickness of the sapwood of the pole. A shielded electrical conduit is emplaced in one such kerf and covered by a wood putty or like filler restoring the surface profile of the pole, and the pole is encased to a thickness of at least about 1/10 inch with a sprayed-on resin mix, such as a mixture of chopped glass fibers and catalyzed polyester resin. Modifications include a covering of cellophane, paper or the like applied between the pole and the plastic coating especially when an oil base preservative is used, and a top cap to prevent entrance of moisture and to ventilate the interior of the pole. Various luminaire support arms and techniques for mounting thereof on the pole are also disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
54 words
A utility pole according to claim 1, wherein said pole is provided with a recess and wherein said support arm bracket means is secured to said pole and occupies said recess, and wherein said resin coating substantially covers said support arm bracket means so that the coated pole has a relatively smooth outward appearance.
Claim 2
Dependent Claim
49 words
A utility pole according to claim 1, comprising lower and upper support arm bracket means attached to the pole prior to application of the protective resin coating, and with both said upper and lower support arm bracket means being at least in part encased by said protective resin coating.
Claim 3
Dependent Claim
86 words
A utility pole assembly including a resin coated utility pole according to claim 1, wherein said electrical conduit means arranged within said kerf enters said resin coating in the lower portion of said pole and emerges from said resin coating in the upper portion of said pole; and laterally extending luminaire support arm means attached to said support arm bracket means substantially at the point of emergence of the electrical conduit means from the pole, said electrical conduit means being channelled within said support arm means.
Claim 4
Dependent Claim
52 words
The utility pole assembly according to claim 4, wherein said pole is emplaced in the ground and said electrical conduit entrance point in the lower portion of said pole is below ground level, said assembly further including illuminating means secured to the distal end of said laterally extending luminaire support arm means.
Claim 5
Dependent Claim
31 words
The utility pole assembly according to claim 4, wherein said kerf is on the same side of said pole as the distal end of said laterally extending luminaire support arm means.
Claim 6
Dependent Claim
30 words
The utility pole assembly according to claim 4, wherein said kerf is on the side of said pole opposite the distal end of said laterally extending luminaire support arm means.
Claim 7
Dependent Claim
39 words
The utility pole assembly according to claim 4, further including an upper brace assembly having a support bar extending tangentially of said pole and a pair of rods secured to said support bar and to said support arm means.
Claim 8
Dependent Claim
24 words
The utility pole assembly according to claim 4, wherein said support arm bracket means is secured to said pole exteriorly of said resin coating.
Claim 9
Dependent Claim
157 words
A resin coated wooden utility pole comprising: a. a wooden pole having rings of heartwood and sapwood encircling a longitudinal axis and also having a lower portion adapted to be inserted into the ground and an upper portion including a bore extending across said pole at an acute angle with said longitudinal axis; b. at least one kerf cut through said sapwood and extending for at least most of the length of said pole; c. an electrical conduit disposed in said kerf; d. a preservative impregnating at least most of the sapwood and at least part of the heartwood of the kerfed pole; e. a substantially impervious, protective resin coating covering the exterior surface of said pole for at least most of the length thereof, and being disposed to span but not fill said kerf; and f. luminaire support arm means extending through said bore and terminating in a downwardly curved lower end secured to said pole.
Claim 10
Dependent Claim
40 words
The utility pole assembly according to claim 10, further including an auxiliary brace secured to the side of said pole opposite said downwardly curved end, the said auxiliary brace extending upwardly and laterally into engagement with said support arm means.
Claim 11
Dependent Claim
168 words
A utility pole assembly comprising: a. a pole having interiorly placed electrical conduit means extending within the pole from the lower portion to the upper portion of the pole and emerging from the pole below the top thereof; b. luminaire support means fastened to and supported by the pole in the upper portion thereof, said luminaire support means comprising a curved tubular member with the lower end thereof fastened to the pole substantially at the point of emergence of the electrical conduit means, said tubular member extending in curved pattErn away from the pole and through an inclined hole passing substantially through the center of the pole then emerging from the pole at a point above and on the opposite side of the pole from the aforesaid point of emergence of the electrical conduit means from the pole, said electrical conduit means being housed in said tubular member and extending the length thereof, and c. luminaire means fastened to said support arm means at the outer end thereof.
Claim 12
Dependent Claim
55 words
A utility pole assembly according to claim 12, further comprising auxiliary support arm means attached to the pole about diametrically opposite the aforesaid point of emergence of the electrical conduit means from the pole and extending upwardly along a curved arc to a point of connection with the support arm means containing the electrical conduit.
Claim 13
Dependent Claim
38 words
A utility pole assembly according to claim 13, including a single metal band encircling the pole and attaching the lower end of said tubular member and the lower end of said auxiliary support arm means to the pole.
