Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
227 words
A meter pit comprising: a hollow surrounding wall having a top end and a bottom end with top and bottom openings leading to the interior of said surrounding wall, said top end of said surrounding wall having an upper circular edge with a given inner diameter, an upper annular wall extending outward from said upper circular edge to an outer edge, an outer cylindrical wall extending upward from said outer edge of said upper annular wall, to a top circular edge, a top annular wall extending inward from said top circular edge to an inner edge, an inner cylindrical wall extending downward from said inner edge defining said top opening with an inside diameter less than said inner diameter of said upper circular edge, a plurality of spaced apart slots formed in said top annular wall and said inner cylindrical wall for receiving lugs of an upper lid cover, each slot comprises: two spaced apart side walls extending outward from said inner cylindrical wall to an intermediate outer wall spaced inward from said outer cylindrical wall, said two spaced apart side walls and said intermediate wall extending downward from said top annular wall to a bottom slot wall which joins said inner cylindrical wall above the level of said upper annular wall such that said slot extends from said inner cylindrical wall outward to said intermediate wall.
Claim 2
Dependent Claim
227 words
A meter pit comprising: a hollow surrounding wall having a top end and a bottom end with top and bottom openings leading to the interior of said surrounding wall, said top end of said surrounding wall having an upper circular edge with a given inner diameter, an upper annular wall extending outward from said upper circular edge to an outer edge, an outer cylindrical wall extending upward from said outer edge of said upper annular wall, to a top circular edge, a top annular wall extending inward from said top circular edge to an inner edge, an inner cylindrical wall extending downward from said inner edge defining said top opening with an inside diameter less than said inner diameter of said upper circular edge, a plurality of spaced apart slots formed in said top annular wall and said inner cylindrical wall for receiving lugs of an upper lid cover, each slot comprises: two spaced apart side walls extending outward from said inner cylindrical wall to an intermediate outer wall spaced inward from said outer cylindrical wall, said two spaced apart side walls and said intermediate wall extending downward from said top annular wall to a bottom slot wall which joins said inner cylindrical wall above the level of said upper annular wall such that said slot extends from said inner cylindrical wall outward to said intermediate wall.
Claim 3
Dependent Claim
