Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A service connection clamp comprising a flexible thin wall band, lug means disposed to tighten the band, a band-type gasket disposed internally of the band for contact with a pipe, said band and said gasket having aligned openings therein, said band being permanently deformed inwardly around said opening therein to form an inwardly projecting annular ring depression around said opening resistant to distortion under pressure, the thickness of the band deformed inwardly being substantially the same as the remainder of the band, said inward deformation of said band causing a corresponding inward deformation in said gasket upon firm contact between the band and gasket, said inward deformation of said gasket providing an annular sealing ring of increased pressure by said deformed gasket around a given surface of the pipe when the clamp is applied, connection means having an outlet therein aligned with the openings in the band and gasket, said connection means being disposed entirely outwardly of the outer surface of said band, and means securing said connection means to said band.
Claim 2
Dependent Claim
