Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 181 words
In combination with a pipe coupling for interconnecting a pair of aligned pipe sections compriSed of a sleeve around said pipe sections having conical end seats, an elastomeric gasket in each end seat having a tapered nose section, a pair of follower rings located at the opposite ends of said sleeve, each having an inner annular portion adjacent a rear annular face of said gasket, and means for drawing said follower rings together, a pair of annular connectors of flexible electrically conductive material, each being located adjacent a said gasket and including an axially extending cylindrical portion located between the gasket and the outer pipe surface and integral radially extending portions located between the gasket and the adjacent follower ring, said axially extending portion of each said connector being comprised of spaced apart segments formed by a first series of notches along one side of the connector, said radially extending portions of each said connector being comprised of segments formed by a second series of spaced apart notches along the other side of said connector and offset from said first notches.
Claim 2
Dependent Claim 181 words
In combination with a pipe coupling for interconnecting a pair of aligned pipe sections compriSed of a sleeve around said pipe sections having conical end seats, an elastomeric gasket in each end seat having a tapered nose section, a pair of follower rings located at the opposite ends of said sleeve, each having an inner annular portion adjacent a rear annular face of said gasket, and means for drawing said follower rings together, a pair of annular connectors of flexible electrically conductive material, each being located adjacent a said gasket and including an axially extending cylindrical portion located between the gasket and the outer pipe surface and integral radially extending portions located between the gasket and the adjacent follower ring, said axially extending portion of each said connector being comprised of spaced apart segments formed by a first series of notches along one side of the connector, said radially extending portions of each said connector being comprised of segments formed by a second series of spaced apart notches along the other side of said connector and offset from said first notches.
Claim 3
Dependent Claim 96 words
An electrical connector for a pipe coupling comprising a sheet metal strip bent along a longitudinal break line to form a first cylindrically shaped portion adapted to fit around a pipe, said first portion having a first series of notches extending inwardly from one side edge of said connector to form axially extending segments, and a second portion integral with said first portion comprised of a plurality of radially extending segments formed by a second series of notches spaced apart along the other side edge of said connector and offset from said first series of notches.
Claim 4
Dependent Claim 96 words
An electrical connector for a pipe coupling comprising a sheet metal strip bent along a longitudinal break line to form a first cylindrically shaped portion adapted to fit around a pipe, said first portion having a first series of notches extending inwardly from one side edge of said connector to form axially extending segments, and a second portion integral with said first portion comprised of a plurality of radially extending segments formed by a second series of notches spaced apart along the other side edge of said connector and offset from said first series of notches.
