Patent ID: 7617843

Claim:
A split sleeve assembly for repairing a leak in a fluid conducting pipe, said sleeve assembly comprising: a longitudinally extending body defining a cylindrically shaped enclosure extending along a first axis with opposite open ends and including an upper half section and a lower half section connectable together around a pipe; each of said half sections including a pair of inwardly projecting spaced apart semi-circular C-shaped flanges with an inner surface in close proximity to the pipe and with the flanges in said upper half section aligned with the flanges in said lower half section and with one of said flanges on each side of a leak to thereby form three hollow chambers with a center chamber and two end chambers with each end chamber between the leak in the pipe and the ends of said enclosure; each of said upper and said lower half sections including a pair of outwardly projected longitudinally extending flanges extending along opposite sides of said half sections parallel to said first axis and adapted to mate with the flanges on said other of said half sections; a gasket between said longitudinally extending flanges; a plurality of bolts and each of said longitudinally extending flanges including a plurality of bolt holes with said bolts passing therethrough to form a fluid tight connection along both sides of said half sections; a mass of packing material disposed in each of said two end chambers; and wherein said split sleeve assembly includes a pair of two piece gland elements and a pair of split sealing rings with one of said gland elements and one of said two piece sealing rings disposed around the pipe adjacent to said opposite ends of said body, and each pair of said two piece gland elements forming a boss for extending into one of said end chambers for sealing the opposite open ends of each enclosure and for compressing the packing material and each of said half sections including two parallel spaced apart outwardly extending mounting brackets including a bolt hole in each of said brackets; a swivable bolt assembly disposed between each pair of mating brackets with an opposite end threaded to receive a nut and where each of said two piece gland elements define a pair of U-shaped openings with one of said openings on an outer periphery of said gland element for receiving a shank of said bolt and a lug nut for drawing said gland element inwardly to tightly engage with an open end of said chamber; an injection valve disposed in said upper section for injecting packing material into the chamber between an open end of the body and the leak, and a drainage valve for draining fluid out of the space between the C-shaped flanges on opposite sides of the leak in the pipe.
