Pressurized underground cable pedestal

Claim 2

A pedestal closure for enclosing abOve-ground extensions of underground cables comprising, a first riser portion, a second riser portion, said first and second riser portions mating and forming an upper pedestal portion comprising a splice chamber, an intermediate tapered pedestal portion and a lower relatively narrow pedestal portion, each of said riser portions having a curved internal element in said relatively narrow pedestal portion and the elements of the two riser portions being opposed and defining plural spaced cable chambers, means forming a seal between said first and second riser portions, a cap engaging with said riser portions and closing said splice chamber defined thereby, the cap including sealing means between an edge of the cap and edges of the first and second riser portions which the cap abuts, means maintaining the riser portions in contact, means in said splice chamber for supporting cables, and cable terminal blocks supported on the exterior of one of said riser portions.

Claim 3

A pedestal enclosure for enclosing above-ground extensions of underground cables comprising, a first riser portion, a second riser portion, said first and second riser portions mating and forming an upper pedestal portion comprising a splice chamber, an intermediate tapered pedestal portion and a lower relatively narrow pedestal portion, each of said riser portions having a curved internal element in said relatively narrow pedestal portion and the elements of the two riser portions being opposed and defining plural spaced cable chambers, means forming a seal between said first and second riser portions, a cap engaging with said riser portions and closing said splice chamber defined thereby, the cap including sealing means between an edge of the cap and edges of the first and second riser portions which the cap abuts, means maintaining the riser portions in contacts, means in said splice chamber for supporting cables, ribs in each cable chamber defining an upper seal chamber at a portion of each cable chamber adjacent said splice chamber, ribs defining a lower seal chamber adjacent the portion of the cable chamber communicating with the ground, and said means for supporting cables comprising loops on the interior wall of said splice chamber on one of said riser portions.

Claim 4

A pedestal enclosure for enclosing above-ground extensions of underground cables comprising, a first riser portion, a second riser portion, said first and second riser portions mating and forming an upper pedestal portion comprising a splice chamber, an intermediate tapered pedestal portion and a lower relatively narrow pedestal portion, each of said riser portions having a curved internal element in said relatively narrow pedestal portion and the elements of the two riser portions being opposed and defining plural spaced cable chambers, means forming a seal between said first and second riser portions, a cap engaging with said riser portions and closing said splice chamber defined thereby, the cap including sealing means between an edge of the cap and edges of the first and second riser portions which the cap abuts, means maintaining the riser portions in contacts, means in said splice chamber for supporting cables, ribs in each cable chamber defining an upper seal chamber at a portion of each cable chamber adjacent said splice chamber, ribs defining a lower seal chamber adjacent the portion of the cable chamber communicating with the ground, and said means for supporting cables comprising loops on the interior wall of said splice chamber on one of said riser portions.

Claim 5

The pedestal of claim 2. wherein said cap comprises a bolt extending downwardly from the center thereof into said splice chamber, a threaded tubular member having threaded engagement on said bolt, hooks extending from said threaded tubular member, and further comprising loops on the inner walls of said riser portions retaining said hooks, whereby said cap may be securely fastened to said riser portions by rotation thereof and thereby form a seal for said splice chamber.

Claim 6

The pedestal of claim 3 wherein the means forming a seal between the riser portions comprises flanges at opposite sides of each riser portion.

Claim 7

The pedestal of claim 4 in which the means maintaining said first and second riser portions in contact comprises first and second slidable closure members, each closure member containing one flange of each riser portion in abutment.

Claim 8

A pedestal closure for enclosing above-ground extensions of underground cables comprising, a first riser portion, a second riser portion, said first and second riser portions mating and forming an upper pedestal portion comprising a splice chamber, an intermediate tapered pedestal portion and a lower relatively narrow pedestal portion, each of said riser portions having a curved internal element in said relatively narrow pedestal portion and the elements of the two riser portions being opposed and defining plural spaced cable chambers, means forming a seal between said first and second riser portions, a cap engaging with said riser portions and closing said splice chamber defined thereby, the cap including sealing means between an edge of the cap and edges of the first and second riser portions which the cap abuts, means maintaining the riser portions in contact, means in said splice chamber for supporting cables, an air dam bushing extending through one of said riser portions for housing cables leading from said splice chamber to the exterior of said pedestal, terminal blocks supported on the exterior of one of said riser portions, and said cap comprising a bolt extending downwardly from the center thereof into said splice chamber, a threaded tubular member threaded on said bolt, hooks extending from said threaded tubular member, and further comprising loops on the inner walls of said riser portions retaining said hooks, whereby said cap may be secured to said riser portions by rotation thereof and thereby form a seal for the splice chamber.

Claim 9

A pedestal closure for enclosing above-ground extensions of underground cables comprising, a first riser portion, a second riser portion, said first and second riser portions mating and forming an upper pedestal portion comprising a splice chamber, an intermediate tapered pedestal portion and a lower relatively narrow pedestal portion, each of said riser portions having a curved internal element in said relatively narrow pedestal portion and the elements of the two riser portions being opposed and defining plural spaced cable chambers, means forming a seal between said first and second riser portions, a cap engaging with said riser portions and closing said splice chamber defined thereby, the cap including sealing means between an edge of the cap and edges of the first and second riser portions which the cap abuts, means maintaining the riser portions in contact, means in said splice chamber for supporting cables, an air dam bushing extending through one of said riser portions for housing cables leading from said splice chamber to the exterior of said pedestal, terminal blocks supported on the exterior of one of said riser portions, and said cap comprising a bolt extending downwardly from the center thereof into said splice chamber, a threaded tubular member threaded on said bolt, hooks extending from said threaded tubular member, and further comprising loops on the inner walls of said riser portions retaining said hooks, whereby said cap may be secured to said riser portions by rotation thereof and thereby form a seal for the splice chamber.
