Abstract
Abstract Spacing member for wire group in electrical overhead lines capable of ensuring a constant rate of damp for the vibrations of wires connected thereto. The spacing member includes a central body to which a plurality of anchoring clips for the electrical wires are connected. The connection between the clips and central body is provided by movable arms rockingly carried on pins of ovoidal cross-section with the interposition of cores made of resilient material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
202 words
A spacing member for wire groups in electrical overhead lines, comprising a central bearing body carrying a plurality of arms, one arm for each wire, equally spaced apart on the periphery of said body and having the end thereof in the form of a fork, wherein the two legs of the fork are passed tHrough by a respective hole of a cross-section other than circular, wherein each of said arms integral with the central body are associated with a respective movable arm carrying at each end a large eye with a bore of a cross-section other than circular, by one of its ends this movable arm being pivoted at the fork-like end of the associated rigid arm of the central body by a pin of a crosssection other than circular, and with the interposition of two cores made of resilient material, these cores being internally hollow and passed through by said pin, while the other end of the movable arm with the other, large eye thereof similarly by a similar pin of a cross-section other than circular similarly passing through two internally hollow cores of resilient material, is pivoted on the fork-like end of a jaw intended for clamping a respective wire.
Claim 2
Dependent Claim
202 words
A spacing member for wire groups in electrical overhead lines, comprising a central bearing body carrying a plurality of arms, one arm for each wire, equally spaced apart on the periphery of said body and having the end thereof in the form of a fork, wherein the two legs of the fork are passed tHrough by a respective hole of a cross-section other than circular, wherein each of said arms integral with the central body are associated with a respective movable arm carrying at each end a large eye with a bore of a cross-section other than circular, by one of its ends this movable arm being pivoted at the fork-like end of the associated rigid arm of the central body by a pin of a crosssection other than circular, and with the interposition of two cores made of resilient material, these cores being internally hollow and passed through by said pin, while the other end of the movable arm with the other, large eye thereof similarly by a similar pin of a cross-section other than circular similarly passing through two internally hollow cores of resilient material, is pivoted on the fork-like end of a jaw intended for clamping a respective wire.
Claim 3
Dependent Claim
87 words
A spacing member as claimed in claim 1, wherein said cores of resilient material comprise an internally hollow body outwardly carrying an annular ridge and a truncated cone extension leading from the plane of the annular ridge and tapering in the direction of the longitudinal axis of said core, whereas the internal bore of a cross-section other than circular is tapering as a truncated cone in the opposite direction, with the major base at the plane comprising the minor base for the truncated cone of said extension.
Claim 4
Dependent Claim
59 words
A spacing member as claimed in claim 2, wherein said cores are arranged in each link so that the extension thereof inserts in the large eye of the movable arm, while the annular ridge abuts against the respective side wall of the large eye and bears on the inner surface of the fork, wherein the large eye is inserted.
Claim 5
Dependent Claim
81 words
A spacing member as claimed in claim 3, wherein in each articulation of said spacing member, between the outer surface of the pin passing through the pair of cores and the inner surface of the bore in said cores, as well as between the outer surface of the core extensions and the inner surface of the large eye in each of the movable arms, an annular space is provided and progressively decreases as the stress exerted by the respective wire increases.
