Abstract
Abstract A clamping member for securing pipe portions of an automobile exhaust system in which the clamping member comprises first and second generally vertically extending end flanges and a generally horizontally extending section intermediate of and interconnecting the first and second end flanges with each of the end flanges having a cut-out portion for reception of a pipe portion to be clamped therein and first and second sleeve portions adjacent opposite sides of the respective end flange for reception of the ends of a U-bolt; wherein the first and second end flanges, the section interconnecting the first and second end flanges, and the sleeve portions are formed from a one-piece blank.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
A clamping member using a pair of U-bolts for securing pipe portions of an automobile exhaust system to each other, said clamping member comprising first and second generally vertically extending end flanges spaced from each other, a generally horizontally extending section intermediate of and connecting to each of said first and second end flanges at an edge thereof, each of said end flanges having a cut-out portion on an opposite edge from the edge connected to said intermediate section for reception of a pipe portion to be clamped therein, first and second sleeve portions connected to remaining opposite edges of each of said end flanges adapted to receive and support respective legs of each of the U-bolts, said first and second end flanges, said intermediate section, and said sleeve portions being integral and formed from a single blank.
Claim 2
Dependent Claim
138 words
A clamping member using a pair of U-bolts for securing pipe portions of an automobile exhaust system to each other, said clamping member comprising first and second generally vertically extending end flanges spaced from each other, a generally horizontally extending section intermediate of and connecting to each of said first and second end flanges at an edge thereof, each of said end flanges having a cut-out portion on an opposite edge from the edge connected to said intermediate section for reception of a pipe portion to be clamped therein, first and second sleeve portions connected to remaining opposite edges of each of said end flanges adapted to receive and support respective legs of each of the U-bolts, said first and second end flanges, said intermediate section, and said sleeve portions being integral and formed from a single blank.
Claim 3
Dependent Claim
33 words
The clamping member as defined in claim 1 wherein each of said sleeve portions is generally tubular and is formed by rolling a previously laterally extending portion of the end flange integral therewith.
Claim 4
Dependent Claim
34 words
The clamping member as defined in claim 2 wherein each of said cut-out portions is generally semicircular and includes a plurality of teeth or serrations for gripping a pipe portion to be secured thereby.
Claim 5
Dependent Claim
133 words
The clamping member as defined in claim 1, 2, or 3 in combination with a conversion bracket for adapting said clamping member to receiving and securing a flexible pipe portion without cutting into the latter, said conversion bracket being generally U-shaped in configuration, of substantially greater width than the thickness of said clamping member, and having an apertured lug at each end thereof for registration with the top of the sleeve portions of one of said end flanges for passage of a U-bolt and a pair of downwardly directed ears, which in assembly of said bracket on said one of said end flanges will extend along opposite sides of said one of said end flanges to ensure that bracket will remain in substantially the same plane with said one of said end flanges.
