Abstract
Abstract A splice case for use on several different types of sheathed or armored multi-conductor telephone and utility cables having the ability of accommodating both double and single sheath cables, on either pressurized or non-pressurized lines for use in buried, conduit or aerial applications. The case includes grippers for securely anchoring the sheaths of the cables to the case to prevent tension loads from damaging the splice, and unique sealing collars for maintaining the moisture-proof integrity of the case when unpressurized and for maintaining positive pressure on pressurized cable systems.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
253 words
A cable splice case for connecting at least one electrical Cable to at least one other electrical cable where such cables are of the type that have a bundle of insulated conductors surrounded by at least one metallic sheath covered by an outer insulating jacket, the combination comprising: a casing comprised of a pair of mating halves, means sealably connecting said mating halves, a plurality of apertures in said casing located between said mating halves with part of each of said apertures formed in one said half and the remainder of the aperture formed in the other half, each aperture including an annular groove formed in said mating halves and annular projections on each side of said groove; gripper means adapted to receive a cable end therein, each said gripper means comprising a cylindrical housing formed of a pair of mating halves, inlet and outlet apertures located at opposite ends of said housing, said apertures being aligned with the principal axis of said housing, means provided in said housing ends for selectively enlarging the diameter of one or both of said apertures to accommodate cables of varying sizes, said housing being capable of containing a quantity of thermosetting molding compound for retaining a cable end therein, said cylindrical gripper housing including means engaging one of said annular projections formed in the mating halves of the aforesaid casing and sealing means cooperatively engaging said apertures in said casing and adapted to engage an outer surface of a cable for sealably closing each said aperture.

Claim 3
Dependent Claim
55 words
A cable splice case as set forth in claim 1 wherein said gripper means further includes: a third aperture disposed in a radial peripheral surface thereof and adapted to pass an electrically conducting ground lead so as to be connected to said sheath, and a fourth aperture in said housing for injecting said molding compound.
Claim 4
Dependent Claim
63 words
A cable splice case of the type set forth in claim 2 wherein said gripper housing further includes an annular groove formed in the outer radial periphery thereof, said groove being located closer to one end of said housing then the other, said annular groove being engaging one of said annular projections in said casing to anchor the gripper means with respect thereto.
Claim 5
Dependent Claim
120 words
A cable splice case of the type set forth in claim 3 wherein said sealing means comprises: a resilient sealing member positioned in said apertures to said casing and having a substantially cylindrical outer sealing portion, a planar end piece formed integrally with said outer portion and located at one end thereof, an aperture in said planar end piece, said apertures being coaxial with said outer portion, a sealing boot formed integrally with said end piece, said boot having a substantially cylindrical wall positioned about and coaxial with said aperture in said end piece the inner surface of said cylindrical wall of said boot being serrated, said inner surface being adapted to sealably engage an outer surface of said cable.
Claim 6
Dependent Claim
82 words
A cable splice case of the type set forth in claim 4 wherein said sealing means further includes: a rigid cylindrical member positioned within the outer cylindrical sealing portion of said sealing member, said rigid member biasing said sealing portion outwardly; a rigid disc element positioned adjacent the exterior of said end piece, the radial dimensions of said disc being substantially coterminous with that of said end piece, said disc having a central aperture aligned with the aperture in said end piece.
Claim 7
Dependent Claim
120 words
A cable splice case of the type set forth in claim 1 wherein said sealing means comprises: a resilient sealing member positioned in said apertures to said casing and having a substantially cylindrical outer sealing portion, a planar end piece formed integrally with said outer portion and located at one end thereof, an aperture in said planar end piece, said aperture in said end piece being coaxial with said outer portion, a sealing boot formed integrally with said end piece, said boot having a substantially cyLindrical wall positioned about and coaxial with said aperture, the inner surface of said cylindrical wall of said boot being serrated, said inner surface being adapted to sealably engage an outer surface of said cable.
Claim 8
Dependent Claim
82 words
A cable splice case of the type set forth in claim 6 wherein said sealing means further includes: a rigid cylindrical member positioned within the outer cylindrical sealing portion of said sealing member, said rigid member biasing said sealing portion outwardly; a rigid disc element positioned adjacent the exterior of said end piece, the radial dimensions of said disc being substantially coterminous with that of said end piece, said disc having a central aperture aligned with the aperture in said end piece.
Claim 9
Dependent Claim
81 words
A cable splice case of the type set forth in claim 7, wherein said sealing means further includes: flat toroidal sealing members composed of resilient material, said toroidal members being positioned in said casing apertures adjacent said rigid disc element, the central aperture of said toroidal member being aligned with the aperture in said disc, the aperture of said toroidal member being provided with a radially disposed annular flange, said flange adapted to sealably engage an outer surface of said cable.
