Abstract
Abstract Repair fittings are provided sealing ruptures or leaks in existing piping systems. The fittings are economical to produce and can be simply installed to provide effective and reliable leak protection. The fittings are of the gasket type and include a pair of substantially identical housing halves which can be fixedly attached to enclose a piping coupling and sections of the accompanying piping. The gaskets are positioned in grooves formed in the surface of each housing half. In assembly, the gaskets compressively mate to provide a fluid tight seal between the two halves with multiple fluid tight seals being formed around the pipe sections encompassed by the fitting.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
A fitting for repair of leaking pipe couplings comprising a pair of substantially identical coupling housing halves, the interior surface of each half including a centrally positioned cavity, a plurality of recessed paths extending from said cavity to the periphery of said housing and an uninterrupted, continuous groove formed in said surface surrounding the perimeter of said cavity and extending transversely across each of said paths at a plurality of positions longitudinal of said paths, said housing halves being adapted for aligned fixed attachment around a pipe coupling and a section of each of the pipes attached thereto with said coupling being positioned within a chamber formed by said cavities in said halves and said pipes being positioned within passageways formed by said paths in said halves, a continuous elastomeric gasket means positioned within a continuous passage formed by said grooves in said halves, said gasket means in said passage forming an uninterrupted, continuous fluid tight seal surrounding said chamber and crossing said passageways at a plurality of positions longitudinal thereof when said halves are fixedly attached whereby a leak at said coupling is surrounded and said leak is enclosed by said fluid tight seal.
Claim 2
Dependent Claim
195 words
A fitting for repair of leaking pipe couplings comprising a pair of substantially identical coupling housing halves, the interior surface of each half including a centrally positioned cavity, a plurality of recessed paths extending from said cavity to the periphery of said housing and an uninterrupted, continuous groove formed in said surface surrounding the perimeter of said cavity and extending transversely across each of said paths at a plurality of positions longitudinal of said paths, said housing halves being adapted for aligned fixed attachment around a pipe coupling and a section of each of the pipes attached thereto with said coupling being positioned within a chamber formed by said cavities in said halves and said pipes being positioned within passageways formed by said paths in said halves, a continuous elastomeric gasket means positioned within a continuous passage formed by said grooves in said halves, said gasket means in said passage forming an uninterrupted, continuous fluid tight seal surrounding said chamber and crossing said passageways at a plurality of positions longitudinal thereof when said halves are fixedly attached whereby a leak at said coupling is surrounded and said leak is enclosed by said fluid tight seal.
Claim 3
Dependent Claim
75 words
The fitting of claim 1 wherein said groove in each of said housing halves is bifurcated adjacent each of said recessed paths forming two grooved notches across each of said paths with said elastomeric gasket means positioned therein providing a double fluid tight seal around each of said pipes in said passageways when said halves are attached whereby said uninterrupted, continuous fluid seal includes primary and secondary seals in each passageway for enclosing said leak.
Claim 4
Dependent Claim
13 words
The fitting of claim 1 wherein said housing halves are fabricated of plastic.
Claim 5
Dependent Claim
13 words
The fitting of claim 1 wherein said elastomeric gaskets are fabricated of rubber.
Claim 6
Dependent Claim
23 words
The fitting of claim 1 wherein said pipe coupling is selected from the group consisting of straight couplings, elbow couplings and T couplings.
Claim 7
Dependent Claim
22 words
The fitting of claim 1 including a pipe coupling positioned within said chamber with pipes attached thereto and extending through said passageways.
