Abstract
Abstract An enclosure for an electric cable splice suitable for burial in the ground. An enclosure which provides moisture-proofing and mechanical protection for the splice. A pair of shells which slide together to form a box-like enclosure having a main compartment, an intermediate compartment, and an entrance passage. A pair of cables is positioned in the entrance passage with the cables passing through the intermediate compartment into the main compartment where the splices of pairs of conductors are located. Each of the shells has a quantity of sealant in the main section so that when the two sections are brought together with the cable splice there between, the splice components are completely surrounded by the sealant in the main compartment, and sealant is forced into the intermediate compartment around the cables.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
82 words
An enclosure for an electric cable splice, comprising: a first generally rectangular shell having a main section, an intermediate section and an entrance section; and a second generally rectangular shell having a main section, an intermediate section and an entrance section; with one of said shells sliding over the other of said shells bringing said main sections together to form a main compartment, said intermediate sections together to form an intermediate compartment, and said entrance sections together to form an entrance passage.
Claim 2
Dependent Claim
82 words
An enclosure for an electric cable splice, comprising: a first generally rectangular shell having a main section, an intermediate section and an entrance section; and a second generally rectangular shell having a main section, an intermediate section and an entrance section; with one of said shells sliding over the other of said shells bringing said main sections together to form a main compartment, said intermediate sections together to form an intermediate compartment, and said entrance sections together to form an entrance passage.
Claim 3
Dependent Claim
33 words
An enclosure as defined in claim 1 including a body of sealant in said main section of said first shell, and a body of sealant in said main section of said second shell.
Claim 4
Dependent Claim
51 words
An enclosure as defined in claim 2 with at least one of said shells having a barrier member between the main and intermediate sections thereof, with a slot in said barrier member for receiving spliced cables, with said slot providing a passage of reduced size between said main and intermediate sections.
Claim 5
Dependent Claim
18 words
An enclosure as defined in claim 3 with said shells having inter-engaging elements for holding said shells together.
Claim 6
Dependent Claim
45 words
An enclosure as defined in claim 4 wherein said inter-engaging elements include a first opening in a wall of one shell and a first boss in a wall of the other shell and positioned for entering said first opening when said shells are brought together.
Claim 7
Dependent Claim
75 words
An enclosure as defined in claim 4 wherein said inter-engaging elements include first and second spaced openings in walls of one shell and first and second spaced bosses in walls of the other shell, with said first boss positioned for entering said first opening when said shells are brought together to a first stage and with said second boss positioned for entering said second opening when said shells are brought together to a second stage.
Claim 8
Dependent Claim
25 words
An enclosure as defined in claim 4 wherein each of said entrance sections has opposed walls at the outer ends thereof diverging in continuous curves.
Claim 9
Dependent Claim
134 words
An enclosure as defined in claim 1 wherein said entrance passage is of a first cross-sectional area to receive a pair of cables, said intermediate compartment is of a second cross-sectional area larger than said first cross-sectional area, and said main compartment is of a third cross-sectional area larger than said second cross-sectional area, and with each of said shells having a barrier member between the main and intermediate sections thereof with a slot therein, with said barrier members overlapping when said shells are brought together so that said slots define an interior passage of substantially the same cross-sectional area as said first cross-sectional area of said entrance passage, and with said entrance passage and interior passage in alignment for positioning the pair of cables in said interior compartment spaced from the walls thereof.
Claim 10
Dependent Claim
33 words
An enclosure as defined in claim 8 including a body of sealant in the main section of said first shell, and a body of sealant in the main section of said second shell.

Dependent Claim
62 words
An enclosure as defined in claim 8 including a body of sealant in the main section of said first shell, and a body of sealant in the main section of said second shell, with the amount of said sealant in said main sections such that sealant is forced from said main compartment into said intermediate compartment when said shells are brought together.
Claim 12
Dependent Claim
18 words
An enclosure as defined in claim 9 with said shells having inter-engaging elements for holding said shells together.
Claim 13
Dependent Claim
45 words
An enclosure as defined in claim 10 wherein said inter-engaging elements include a first opening in a wall of one shell and a first boss in a wall of the other shell and positioned for entering said first opening when said shells are brought together.
Claim 14
Dependent Claim
75 words
An enclosure as defined in claim 10 wherein said inter-engaging elements include first and second spaced openings in walls of one shell and first and second spaced bosses in walls of the other shell, with said first boss positioned for entering said first opening when said shells are brought together to a first stage and with said second boss positioned for entering said second opening when said shells are brought together to a second stage.
Claim 15
Dependent Claim
25 words
An enclosure as defined in claim 10 wherein each of said entrance sections has opposed walls at the outer ends thereof diverging in continuous curves.
