Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
147 words
A pipe joint for two sections of pipe in end-to-end relation, comprising, in combination, a clamping band of flexible, semistiff material bridging the adjoining ends of said pipe sections, a wire-clamping unit consisting of a single strand of wire initially bent in the form of a ''''U'''' providing two initially parallel leg portions connected by a transverse bight portion, said leg portions being first coiled around the periphery of said clamping band adjacent its opposite edges and then passed beneath and through said bight portion in engagement with the underside thereof, each of said coils being independently responsive to a pulling force exerted on the respective ends of said leg portions projecting beyond said bight portion, and means for simultaneously but independently pulling said respective projecting ends to independently tighten said coils around said clamping band, and then reversely bending said projecting ends over said bight portion.
Claim 2
Dependent Claim
147 words
A pipe joint for two sections of pipe in end-to-end relation, comprising, in combination, a clamping band of flexible, semistiff material bridging the adjoining ends of said pipe sections, a wire-clamping unit consisting of a single strand of wire initially bent in the form of a ''''U'''' providing two initially parallel leg portions connected by a transverse bight portion, said leg portions being first coiled around the periphery of said clamping band adjacent its opposite edges and then passed beneath and through said bight portion in engagement with the underside thereof, each of said coils being independently responsive to a pulling force exerted on the respective ends of said leg portions projecting beyond said bight portion, and means for simultaneously but independently pulling said respective projecting ends to independently tighten said coils around said clamping band, and then reversely bending said projecting ends over said bight portion.
Claim 3
Dependent Claim
31 words
A pipe joint as claimed in claim 1, including a packing sleeve of compressible, leakproof material surrounding the adjoining ends of said pipe sections between the latter and said clamping band.
Claim 4
Dependent Claim
21 words
A pipe joint as claimed in claim 1, wherein the longitudinal extremities of said clamping band are arranged in overlapping relation.
Claim 5
Dependent Claim
21 words
A pipe joint as claimed in claim 2, wherein the longitudinal extremities of said clamping band are arranged in overlapping relation.
Claim 6
Dependent Claim
19 words
A pipe joint as claimed in claim 1, wherein the major portion of said clamping band is transversely corrugated.
Claim 7
Dependent Claim
31 words
A pipe joint as claimed in claim 5, wherein the longitudinal extremities of said clamping band are arranged in overlapping relation, and one of said longitudinal extremitieS is devoid of corrugations.
Claim 8
Dependent Claim
26 words
A pipe joint as claimed in claim 1, including means on said clamping band for slidably retaining the relative positions of said coils on said band.
Claim 9
Dependent Claim
26 words
A pipe joint as claimed in claim 2, including means on said clamping band for slidably retaining the relative positions of said coils on said band.
Claim 10
Dependent Claim
17 words
A pipe joint as claimed in claim 5, wherein said clamping band is formed of stainless steel.
Claim 11
Dependent Claim
40 words
A pipe joint as claimed in claim 7, wherein said coil retaining means comprises a series of staples secured around the periphery of said clamping band in annularly aligned positions, with a sliding clearance between their crowns and said coils.
