Abstract
Abstract A midspan spacer is provided for maintaining a plurality of high voltage, multiple phase electrical conductors in proper relative relationship under varying ambient weather and wind conditions. The spacer is adapted to be positioned midspan between adjacent pole or tower supports for the conductors. Clamp means grippingly engaging each of the conductors are joined to and supported by rigid spacer bars extending there

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
An adjustable midspan spacer for maintaining proximal high voltage conductors in spaced relationship, comprising: separate attachment means corresponding in number to said conductors and operable to grippingly engage one of the latter; a plurality of rigid insulative spacer bars interconnected to define a closed, generally planar, polygonal spacing assembly, said assembly being of dimensions permitting the positioning thereof within the space between said conductors and generally transversely of the longitudinal axes of the latter; and means adjustably connecting each of said separate attachment means to said spacing assembly at fixed, spaced locations thereon, said adjustable connector means permitting independent pivoting movement of each of said separate attachment means relative to said spacing assembly in the plane thereof and about said locations, said adjustable connector means also including mechanism for releasably locking each of said separate attachment means at desired orientations relative to said assembly and in the plane thereof.
Claim 2
Dependent Claim
149 words
An adjustable midspan spacer for maintaining proximal high voltage conductors in spaced relationship, comprising: separate attachment means corresponding in number to said conductors and operable to grippingly engage one of the latter; a plurality of rigid insulative spacer bars interconnected to define a closed, generally planar, polygonal spacing assembly, said assembly being of dimensions permitting the positioning thereof within the space between said conductors and generally transversely of the longitudinal axes of the latter; and means adjustably connecting each of said separate attachment means to said spacing assembly at fixed, spaced locations thereon, said adjustable connector means permitting independent pivoting movement of each of said separate attachment means relative to said spacing assembly in the plane thereof and about said locations, said adjustable connector means also including mechanism for releasably locking each of said separate attachment means at desired orientations relative to said assembly and in the plane thereof.
Claim 3
Dependent Claim
45 words
The midspan spacer of claim 1, wherein said spacer bars are interconnected at the respective extremities thereof to define said spacing assembly, said attachment means being connected to the latter at the points of interconnection of said spacer bars and extending outwardly from said assembly.
Claim 4
Dependent Claim
35 words
The midspan spacer of claim 2, wherein each of said attachment means includes an elongated insulator adjustably connected at one end thereof to said spacing assembly and having conductor-gripping means at the remaining end thereof.
Claim 5
Dependent Claim
47 words
The midspan spacer of claim 3, wherein said conductor-gripping means comprises a saddle clamp adapted to grippingly engage one of said conductors and provided with generally U-shaped yoke structure supporting said saddle clamp and allowing pivoting movement thereof only about an axis extending transversely of the conductor.
Claim 6
Dependent Claim
23 words
The midspan spacer of claim 3, wHerein said conductor-gripping means comprises a grooved knob member configured to receive one of said conductors therein.
Claim 7
Dependent Claim
136 words
The midspan spacer of claim 3 wherein said adjustable connector means comprises: a ferrule secured to each end of each spacer bar which is in opposed, proximal relationship to the end extremity of an adjacent spacer bar, and to each end of the respective insulators remote from the conductor-gripping means thereof, each of said ferrules being provided with an axially extending, transversely apertured segment, the segments of adjacent ferrules being in abutting relationship with the apertures thereof in axial alignment, the abutting faces of adjacent ferrule segments being of generally flat configuration and provided with spaced, outwardly projecting teeth arranged in a circular pattern and in meshing engagement with the teeth of an opposed segment for interlocking adjacent ferrules; and releasable mechanism extending through the aligned apertures of abutting ferrule segments to releasably interconnect the same.
Claim 8
Dependent Claim
73 words
The midspan spacer of claim 6 wherein a transversely apertured spacer is interposed between a pair of said abutting ferrule segments to allow greater degrees of relative rotation therebetween, said apertured spacer comprising a relatively thin element having teeth on the opposed faces thereof, said teeth being in meshing engagement with the teeth of said pair of segments with the aperture of said spacer being in alignment with the apertures of said segments.
Claim 9
Dependent Claim
21 words
The midspan spacer of claim 6 wherein a thin, apertured washer is interposed between a pair of said abutting ferrule segments.
Claim 10
Dependent Claim
26 words
The midspan spacer of claim 1 wherein said spacer bars are formed of fiberglass reinforced epoxy core rod jacketed with a coating of insulative epoxy material.
