Abstract

Abstract A bracket has a top plate for supporting an insulator. A body member depends from the top plate and comprises a plate of metal bent to form a longitudinal channel portion with a pair of side walls and a connecting wall. Side walls of the channel portion have flange extensions thereon which are bent angularly outwardly. The bracket is tapered to a narrower dimension toward the bottom in both its width and depth. The bracket is clamped or bolted to a pole and one embodiment thereof includes tooth means to firmly anchor the bracket against surface movement.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 211 words
A single insulator mounting bracket for supporting an insulator at the top of a power pole comprising: a. a top plate having top and bottom surfaces, b. means in said plate for securing an insulator in supported relation on the top surface thereof, c. a single body member depending integrally from said top plate arranged for mounting engagement against one side only of a pole, d. said body member comprising a single piece of metal plate bent to form in cross section a longitudinal channel-shaped member having a pair of side walls and a connecting wall, e. said side walls of said body member having lesser width toward the bottom wherein said body member is tapered to less depth in upright direction toward the lower end thereof, f. said body member also comprising longitudinal flange extensions on said side walls bent angularly thereto in an outward direction, g. the overall width of said bracket between the outer edges of said flange extension being tapered to a narrowed dimension toward the bottom, h. said body member being arranged to be mounted on a pole with the open portion of the channel facing the pole, i. and one or more bolts extending from said bracket and arranged to be secured to a post.
Claim 2
Dependent Claim 211 words
A single insulator mounting bracket for supporting an insulator at the top of a power pole comprising: a. a top plate having top and bottom surfaces, b. means in said plate for securing an insulator in supported relation on the top surface thereof, c. a single body member depending integrally from said top plate arranged for mounting engagement against one side only of a pole, d. said body member comprising a single piece of metal plate bent to form in cross section a longitudinal channel-shaped member having a pair of side walls and a connecting wall, e. said side walls of said body member having lesser width toward the bottom wherein said body member is tapered to less depth in upright direction toward the lower end thereof, f. said body member also comprising longitudinal flange extensions on said side walls bent angularly thereto in an outward direction, g. the overall width of said bracket between the outer edges of said flange extension being tapered to a narrowed dimension toward the bottom, h. said body member being arranged to be mounted on a pole with the open portion of the channel facing the pole, i. and one or more bolts extending from said bracket and arranged to be secured to a post.
Claim 3
Dependent Claim 51 words
The insulator mounting bracket of claim 1 wherein said flange extensions have apertures therein and said securing means comprise a length adjustable pole band arranged to be disposed on the opposite side of a pole from said bracket and bolts bolting said band and bracket in clamping engagement on the pole.
Claim 4
Dependent Claim 284 words
A single insulator mounting bracket for supporting an insulator at the top of a power pole comprising: a. a top plate having top and bottom surfaces, b. means in said plate for securing an insulator in supported relation on the top surface thereof, c. a single body member depending integrally from said top plate arranged to form a mounting engagement against one side only of a pole, d. said body member comprising a single piece of metal plate bent to form in cross section a longitudinal channel-shaped member having a pair of side walls and a connecting wall, e. said body member also comprising longitudinal flange extensions on said side walls bent angularly thereto in an outward direction, f. the overall width of said bracket between the outer edges of said flange extensions being tapered to a narrowed dimension toward the bottom, g. said body member being arranged to be mounted on a pole with open portion of the channel facing the pole, h. the width of said channel between said side walls being tapered to a narrowed dimension toward the top whereby to have a reverse taper to the overall width taper of the bracket and providing a uniform distance between the side walls at the bend between the side walls and the flange extensions, i. one or more bolts extending from said bracket and arranged to be secured to a post, j. and channel-shaped tooth means on said bracket secured to said body member at said bend between the side walls and the flange extensions and arranged to engage a pole when the bracket is secured in place by said bolts to firmly anchor the bracket against surface movement on the pole.
Claim 5
Dependent Claim 284 words
A single insulator mounting bracket for supporting an insulator at the top of a power pole comprising: a. a top plate having top and bottom surfaces, b. means in said plate for securing an insulator in supported relation on the top surface thereof, c. a single body member depending integrally from said top plate arranged to form a mounting engagement against one side only of a pole, d. said body member comprising a single piece of metal plate bent to form in cross section a longitudinal channel-shaped member having a pair of side walls and a connecting wall, e. said body member also comprising longitudinal flange extensions on said side walls bent angularly thereto in an outward direction, f. the overall width of said bracket between the outer edges of said flange extensions being tapered to a narrowed dimension toward the bottom, g. said body member being arranged to be mounted on a pole with open portion of the channel facing the pole, h. the width of said channel between said side walls being tapered to a narrowed dimension toward the top whereby to have a reverse taper to the overall width taper of the bracket and providing a uniform distance between the side walls at the bend between the side walls and the flange extensions, i. one or more bolts extending from said bracket and arranged to be secured to a post, j. and channel-shaped tooth means on said bracket secured to said body member at said bend between the side walls and the flange extensions and arranged to engage a pole when the bracket is secured in place by said bolts to firmly anchor the bracket against surface movement on the pole.
