Abstract
Abstract A well pipe connector for connecting a horizontal liquid pipe outside a hollow well casing with a vertical liquid pipe extending inside the casing. The connector has a first unit attached to the casing wall and a second unit connected to the vertical pipe and removably attached within the casing to the first unit. The first unit has a plate with a sleeve extending through the casing wall to be connected to the horizontal pipe. The plate side towards the inner side of the casing wall has an annular convex surface with parallel ribs to define a gasket seat and alignment and stop surfaces. The first unit is secured to the casing with a gasket on each side of the casing wall circumjacent the sleeve to provide a fluid tight seal around the hole in the casing. A concave washer is adjacent the outer gasket to provide proper compression and spacing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
246 words
A well pipe connector for joining a horizontal discharge pipe extending into a hollow well casing with a vertical well pipe extending within said casing comprising, in combination, a first unit having a plate with a central aperture and an annular sleeve extending outwardly from said aperture on one side to define a liquid passage through said plate, said sleeve having means on its outer end for securing it to said horizontal discharge pipe with the opposite side of said plate having a generally planar surface, said one side of said plate having an annular, generally convex surface surrounding said sleeve with a pair of ribs on opposed lateRal edges extending parallel to said well casing and terminating short of said annular surface to define a gasket surface circumjacent said sleeve, means on the outer portion of said sleeve for engaging a clamping member whereby said first unit can be attached to said well casing with a first gasket between said annular gasket surface and the inner wall of said well casing and a second gasket between the outer wall of said well casing and said clamping member, and a second unit having a generally planar surface for releasable engagement with said opposite side of said first unit with a liquid passage extending into said planar surface of said second unit and thence downwardly into said well casing to provide a liquid passage from said vertical well pipe through said connector to said horizontal discharge pipe.
Claim 2
Dependent Claim
246 words
A well pipe connector for joining a horizontal discharge pipe extending into a hollow well casing with a vertical well pipe extending within said casing comprising, in combination, a first unit having a plate with a central aperture and an annular sleeve extending outwardly from said aperture on one side to define a liquid passage through said plate, said sleeve having means on its outer end for securing it to said horizontal discharge pipe with the opposite side of said plate having a generally planar surface, said one side of said plate having an annular, generally convex surface surrounding said sleeve with a pair of ribs on opposed lateRal edges extending parallel to said well casing and terminating short of said annular surface to define a gasket surface circumjacent said sleeve, means on the outer portion of said sleeve for engaging a clamping member whereby said first unit can be attached to said well casing with a first gasket between said annular gasket surface and the inner wall of said well casing and a second gasket between the outer wall of said well casing and said clamping member, and a second unit having a generally planar surface for releasable engagement with said opposite side of said first unit with a liquid passage extending into said planar surface of said second unit and thence downwardly into said well casing to provide a liquid passage from said vertical well pipe through said connector to said horizontal discharge pipe.
Claim 3
Dependent Claim
34 words
The pipe connector of claim 1 which further includes means for slidingly engaging said general planar surfaces of said first and second units together whereby said units are held in registry with each other.
Claim 4
Dependent Claim
54 words
The pipe connector of claim 1 wherein said ribs on said opposite side of said first unit extend outwardly beyond said annular gasket surface towards the outer end of said sleeve to provide alignment and stop surfaces adjacent said inner wall of said well casing to align said first unit vertically within said casing.
Claim 5
Dependent Claim
70 words
The pipe connector of claim 1 which further includes a rigid concave washer between said clamping member and said second gasket, said concave washer having a pair of opposed stop lugs extending from its concave surface towards said well casing to provide means for positioning said washer at a fixed minimum distance from said well casing when said clamping member is tightened to assure compression of said first inner gasket.
Claim 6
Dependent Claim
32 words
The pipe connector of claim 1 wherein the radius of curvature of said annular convex surface and of said concave washer are equal and are intermediate the radius of said well casing.
