Abstract
The cross-arms (10) for electricity or telephone lines (13) are mounted on poles (11) by mounting brackets (12) so that the upper faces (17, 18) of the cross-arms (10) are inclined downwardly at approximately 45.degree. to the horizontal. The lines (13) are carried by insulators (14) whose bases (15) are bolted, screwed or clamped to the cross-arm (10). The cross-arms (10) are supported in substantially V-shaped cradles mounted on, or formed integrally with base plates fixed to the poles (11).
Claims17
A bracket for mounting a cross-arm on a utility pole, comprising
- a substantially vertical base plate mountable on the pole,
- means for fastening the base plate to the pole,
- a substantially V-shaped cradle affixed to the base plate to receive and support the cross-arm so that neither side of the V-shaped cradle is substantially horizontal, and
- a pair of straps affixed to the cradle, whereby the straps may be passed over the cross-arm to secure the cross-arm in the cradle.
A bracket for mounting a cross-arm on a utility pole, comprising
- a substantially vertical base plate mountable on the pole,
- means for fastening the base plate to the pole,
- a substantially V-shaped cradle affixed to the base plate to receive and support the cross-arm so that neither side of the V-shaped cradle is substantially horizontal, and
- at least one bolt which can be passed through both the cradle and the cross-arm to secure the cross-arm in the cradle.
A utility structure comprising, in combination,
- a utility pole,
- a pair of mounting brackets affixed to the pole, on opposite sides thereof, and
- a pair of substantially parallel cross-arms supported by the mounting bracket,
- each said mounting bracket comprising a substantially vertical base plate mountable on the pole, means for fastening the base plate to the pole, a substantially V-shaped cradle affixed to the base plate to receive and support the cross-arm so that neither side V-shaped is substantially horizontal, and means on the cradle for receiving a fastener to secure the cross-arm in the cradle, and further comprising
- at least one link assembly interconnecting the cross-arms adjacent the ends thereof to provide stability, each link assembly having a female member attached to one of the cross-arms, and a male member attached to the other of the cross-arms, the male and female members being interconnected by a threaded adjuster.
A utility structure comprising, in combination,
- a utility pole,
- a mounting bracket affixed to the pole, and
- a cross-arm supported by the mounting bracket,
- said mounting bracket comprising a substantially vertical base plate mountable on the pole, means for fastening the base plate to the pole, a substantially V-shaped cradle affixed to the base plate to receive and support the cross-arm so that neither side of the V-shaped cradle is substantially horizontal, and means on the cradle for receiving a fastener to secure the cross-arm in the cradle, and further comprising
- at least one electrical insulator mounted on the cross-arm, for supporting utility lines.
