Abstract
Abstract A spacer for overhead conductors is disclosed. The spacer comprises a unit for resiliently gripping directly about the conductor, the unit being constituted essentially by a pair of jaws adapted to be encircled about the conductor and connected one to another by clamping means. Pads of flexible and resilient material are arranged onto half-sheaths made of metal which directly encircles the conductor. The jaws are provided with recesses having an eccentric bottom surface which differs from the external surface of the pads whereby the pads are engaged in a compression effect when they are inserted therein, and the jaws are brought together by one or more clamping means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A clamp for overhead conductors, comprising, a resilient gripping unit for encircling a longitudinal portion of a conductor, said unit including means for compression and attachment of the same directly about the conductor, a pair of jaws connected one to another, and pads of flexible and resilient material interpositioned between said jaws and adapted to be subjected to compression between said conductor and said jaws, said unit further including half-sheaths mounted between said pads and having their ends profiled so as to define external projections, said jaws including cooperating seating portions and stop portions near the extremities of said seating portions, cooperating with said projections, for limiting the deformation and the compression effect of said pads.
Claim 2
Dependent Claim
116 words
A clamp for overhead conductors, comprising, a resilient gripping unit for encircling a longitudinal portion of a conductor, said unit including means for compression and attachment of the same directly about the conductor, a pair of jaws connected one to another, and pads of flexible and resilient material interpositioned between said jaws and adapted to be subjected to compression between said conductor and said jaws, said unit further including half-sheaths mounted between said pads and having their ends profiled so as to define external projections, said jaws including cooperating seating portions and stop portions near the extremities of said seating portions, cooperating with said projections, for limiting the deformation and the compression effect of said pads.
Claim 3
Dependent Claim
116 words
A clamp for overhead conductors, comprising, a resilient gripping unit for encircling a longitudinal portion of a conductor, said unit including means for compression and attachment of the same directly about the conductor, a pair of jaws connected one to another, and pads of flexible and resilient material interpositioned between said jaws and adapted to be subjected to compression between said conductor and said jaws, said unit further including half-sheaths mounted between said pads and having their ends profiled so as to define external projections, said jaws including cooperating seating portions and stop portions near the extremities of said seating portions, cooperating with said projections, for limiting the deformation and the compression effect of said pads.
Claim 4
Dependent Claim
116 words
A clamp for overhead conductors, comprising, a resilient gripping unit for encircling a longitudinal portion of a conductor, said unit including means for compression and attachment of the same directly about the conductor, a pair of jaws connected one to another, and pads of flexible and resilient material interpositioned between said jaws and adapted to be subjected to compression between said conductor and said jaws, said unit further including half-sheaths mounted between said pads and having their ends profiled so as to define external projections, said jaws including cooperating seating portions and stop portions near the extremities of said seating portions, cooperating with said projections, for limiting the deformation and the compression effect of said pads.
Claim 5
Dependent Claim
23 words
The clamp as defined in claim 1, wherein said pads are half-rings, and said seating portions have corresponding positioning recesses receiving said half-rings.
Claim 6
Dependent Claim
35 words
The clamp as defined in claim 2, wherein said recesses have eccentric bottom portions engaged with said half-rings, the latter having their ends adjacent each other and being compressed one to another between said recesses.
Claim 7
Dependent Claim
45 words
The clamp as defined in claim 3, wherein the outer faces of said half-sheaths have, near the diametral junction plane and starting from said plane, inclined retaining flats which converge on the inner sides of said half-sheaths, co-operating with said adjacent ends of the half-rings.
Claim 8
Dependent Claim
36 words
The clamp as defined in claim 4, wherein said half-sheaths include inner faces, and said outer faces bearing against said half-rings are eccentric relative to said inner faces and to said external projections of the half-sheaths.
Claim 9
Dependent Claim
71 words
The clamp as defined in claim 5 in combination with a spacer bar member, wherein said jaws include bearing faces and one end has a hole therein receiving a connecting screw; said spacer bar member having one end thereof assembled with said bearing face of one of said jaws by said screw, the bearing face of the other jaw having a recess receiving the head of said screw with some clearance.
Claim 10
Dependent Claim
44 words
The combination as defined in claim 6, wherein said pair of jaws is interconnected by at least one bolt constituting part of said means for compression and attachment, said bolt extending freely through one of said jaws and being screwed into the other jaw.
