Abstract
Abstract Apparatus for enclosing splices between two or more multiconductor cables is disclosed. The apparatus includes a unitary support member which has affixed thereto cable ground sheath bonding circuitry, cable support apparatus, and clamps for securing the apparatus to a messenger strand. Completed splice connections are sealed in a unitary, flexible, weatherproof cover.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
Apparatus for enclosing cable splice connections between multiple conductors in at least one cable having an electrical ground sheath and supported by a messenger cable and corresponding mulitple conductors in at least one other cable having an electrical ground sheath and supported by said messenger cable, said apparatus including a unitary support member, means for attaching said support member to said messenger cable, said attaching means also for providing an electrical connection between said support member and said messenger cable, means, affixed to said support member, for providing a flexible electrical connection between said ground sheaths in said one and said other cable and said support member, unitary flexible means for enclosing said splice connections, said flexible means having an inner surface and first and second parallel edges, a portion of said inner surface supported atop said support member such that said first and second parallel edges are juxtaposed to one another, and means for securing said juxtaposed first and second parallel edges to one another.
Claim 2
Dependent Claim
166 words
Apparatus for enclosing cable splice connections between multiple conductors in at least one cable having an electrical ground sheath and supported by a messenger cable and corresponding mulitple conductors in at least one other cable having an electrical ground sheath and supported by said messenger cable, said apparatus including a unitary support member, means for attaching said support member to said messenger cable, said attaching means also for providing an electrical connection between said support member and said messenger cable, means, affixed to said support member, for providing a flexible electrical connection between said ground sheaths in said one and said other cable and said support member, unitary flexible means for enclosing said splice connections, said flexible means having an inner surface and first and second parallel edges, a portion of said inner surface supported atop said support member such that said first and second parallel edges are juxtaposed to one another, and means for securing said juxtaposed first and second parallel edges to one another.
Claim 3
Dependent Claim
33 words
Apparatus in accordance with claim 1 further including means, affixed to said support member, for holding said one cable and said other cable in a predetermined spatial relationship with respect to one another.
Claim 4
Dependent Claim
129 words
Apparatus in accordance with claim 2 wherein said holding means includes first and second members having generally teardrop-shaped cross sections in first and second parallel planes which are perpendicular to a plane containing said support member and axes of symmetry of said first and second members, each of said members having first and second slots oriented at angles of less than ninety degrees with respect to said plane perpendicular with said first and second parallel planes, said slots having a width and a depth at least equal to a diameter of said cables to be held, means, integral with each of said first and second members, for slidably engaging said support member, and means for securing said first and second members on said support member at a specified location.
Claim 5
Dependent Claim
27 words
Apparatus in accordance with claim 1 wherein said unitary support member includes an electrically conductive rod, and an insulative sleeve covering a central portion of said rod.
Claim 6
Dependent Claim
98 words
Apparatus in accordance with claim 1 wherein said means for providing a flexible electrical connection between said ground sheaths and said support member includes, first and second ground cables routed through first and second spaced-apart apertures in said support member, said ground cables being secured in place in said apertures by a staked connection, a plurality of ground sheath bonding clamps, one such clamp affixed to each end of said first and second ground cables, and a plurality of insulative sleeves, one such sleeve affixed about each ground cable segment between said bonding clamp and said staked connection.
Claim 7
Dependent Claim
140 words
Apparatus in accordance with claim 1 wherein said unitary flexible enclosing means includes at least one nozzle on a first side edge of said enclosing means and at least one other nozzle on a second side edge of said enclosing means, each of said nozzles comprised of first and second half sections which are integral with said enclosing means, said first half section having integral therewith along a top edge an extended lip for aligning a top edge of said second half section and for providing an overlapping weatherproof seal between said half sections when they are secured to one another, each of said nozzles further having a variable diameter cross section for accommodating a specified range of cable sizes, and means for securing said top edges and edges opposite thereto together to provide a weatherproof seal at said nozzles.
Claim 8
Dependent Claim
65 words
Apparatus in accordance with claim 1 wherein said securing means includes first and second raised beads extending along a length of said juxtaposed first and second parallel edges, respectively, and a generally U-shaped channel member having inwardly directed lips along top edges, said channel member being slidably engageable with said first and second raised beads to secure said juxtaposed first and second parallel edges together.
