Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A water barrier device for preventing seepage of water along the interface between the exterior of a pipe and a masonry wall in which a portion of the pipe length is permanently and immovably embedded, said barrier device comprising a rigid molded plastic tubular sleeve adapted to be telescoped onto and bonded to the outer surface of the portion of a pipe embraced by and in sealing contact with a waterproof coating for said masonry wall and through which coating said pipe passes, and said sleeve having wide area sealing flange means embracing and projecting outwardly therefrom adapted to be embedded in and sealed to waterproof coating for one face of said masonry wall when installed therein and cooperable therwith to prevent liquid seepage through the wall along the exterior of the pipe.
Claim 2
Dependent Claim
133 words
A water barrier device for preventing seepage of water along the interface between the exterior of a pipe and a masonry wall in which a portion of the pipe length is permanently and immovably embedded, said barrier device comprising a rigid molded plastic tubular sleeve adapted to be telescoped onto and bonded to the outer surface of the portion of a pipe embraced by and in sealing contact with a waterproof coating for said masonry wall and through which coating said pipe passes, and said sleeve having wide area sealing flange means embracing and projecting outwardly therefrom adapted to be embedded in and sealed to waterproof coating for one face of said masonry wall when installed therein and cooperable therwith to prevent liquid seepage through the wall along the exterior of the pipe.
Claim 3
Dependent Claim
30 words
A water barrier device as defined in claim 1 characterized in that said flange means comprises a plurality of annular flanges spaced apart axially of said sleeve and integral therewith.
Claim 4
Dependent Claim
104 words
That improvement in a swimming pool to prevent seepage of water along the interface between a masonry pool wall and the exterior of the water pipe having a short length thereof embedded in the masonry wall below the pool water level, said improvement comprising a tubular sleeve sealingly bonded to the exterior of said pipe along a length thereof embedded in a waterproof coating for the interior surface of the pool wall, said sleeve being embraced by outwardly projecting water seepage barrier means having the surface thereof embedded in and sealingly adherent to said waterproof coating lining the interior surface of the pool wall.
Claim 5
Dependent Claim
104 words
That improvement in a swimming pool to prevent seepage of water along the interface between a masonry pool wall and the exterior of the water pipe having a short length thereof embedded in the masonry wall below the pool water level, said improvement comprising a tubular sleeve sealingly bonded to the exterior of said pipe along a length thereof embedded in a waterproof coating for the interior surface of the pool wall, said sleeve being embraced by outwardly projecting water seepage barrier means having the surface thereof embedded in and sealingly adherent to said waterproof coating lining the interior surface of the pool wall.
Claim 6
Dependent Claim
82 words
That improvement defined in claim 3 characterized in that the inwardly facing sie of said pool wall has a concavity surrounding the adjacent portion of said water pipe and having a depth adequate to accommodate the length of the pipe embraced by said tubular sleeve, and said sleeve being located within said concavity and embedded in and adherent to said waterproof coating thereby to prevent seepage of water from the pool and along the interface between said pipe and said pool wall.
