Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
A formable hose with serpentine shape retentivity and of the type for coupling to nipples with circumferential type clamps, the hose comprising: a polymeric tube having a circumference and length, the tube surrounded with a helical wire and twined reinforcement; a polymeric cover surrounding the tube, helical wire and twined reinforcement, the cover having a first portion of substantially uniform thickness throughout a major portion of the tube circumference and a second portion of a greater thickness than the first portion thickness and continuing throughout a minor portion of the tube circumference, the first portion and second portion of substantially uniform cross section throughout the tube length; and a reformable wire embedded solely in the second portion of the cover and extending generally longitudinally of the tube throughout its length, the reformable wire sufficiently stout to retain the hose in a serpentine shape.
Claim 2
Dependent Claim
143 words
A formable hose with serpentine shape retentivity and of the type for coupling to nipples with circumferential type clamps, the hose comprising: a polymeric tube having a circumference and length, the tube surrounded with a helical wire and twined reinforcement; a polymeric cover surrounding the tube, helical wire and twined reinforcement, the cover having a first portion of substantially uniform thickness throughout a major portion of the tube circumference and a second portion of a greater thickness than the first portion thickness and continuing throughout a minor portion of the tube circumference, the first portion and second portion of substantially uniform cross section throughout the tube length; and a reformable wire embedded solely in the second portion of the cover and extending generally longitudinally of the tube throughout its length, the reformable wire sufficiently stout to retain the hose in a serpentine shape.
Claim 3
Dependent Claim
47 words
The formable hose as claimed in claim 1 wherein the cover has an exterior surface of generally elliptical shape when the hose is viewed in transverse cross section, the exterior surface defining a means for contacting substantially an entire inner peripheral surface of a circumferential type clamp.
Claim 4
Dependent Claim
26 words
The formable hose as claimed in claims 1 or 2 wherein the reformable wire has a diameter that is greater than the first portion cover thickness.
Claim 5
Dependent Claim
25 words
The formable hose as claimed in claims 1 or 2 wherein the helical wire is partially embedded in an outer surface portion of the tube.
Claim 6
Dependent Claim
27 words
The formable hose as claimed in claims 1 or 2 wherein the cover and reformable wire are located along a shallow helix relative to the wire reinforcement.
Claim 7
Dependent Claim
143 words
A formable hose with serpentine shape retentivity and of the type for coupling to nipples with circumferential type clamps, the hose comprising: a polymeric tube having a circumference and length, the tube reinforced with a surrounding twined reinforcement and a helical wire; a polymeric cover surrounding the tube, twined reinforcement and helical wire, the cover having a first portion having thickness throughout a major portion of the tube circumference and a second portion having a greater thickness than the first portion thickness and continuing throughout a minor portion of the tube circumference, the first portion and second portion of substantially uniform cross section throughout the tube length; and a reformable wire embedded solely in the second portion of the cover and extending generally longitudinally of the tube throughout its length, the reformable wire sufficiently stout to retain the hose in a serpentine shape.
Claim 8
Dependent Claim
143 words
A formable hose with serpentine shape retentivity and of the type for coupling to nipples with circumferential type clamps, the hose comprising: a polymeric tube having a circumference and length, the tube reinforced with a surrounding twined reinforcement and a helical wire; a polymeric cover surrounding the tube, twined reinforcement and helical wire, the cover having a first portion having thickness throughout a major portion of the tube circumference and a second portion having a greater thickness than the first portion thickness and continuing throughout a minor portion of the tube circumference, the first portion and second portion of substantially uniform cross section throughout the tube length; and a reformable wire embedded solely in the second portion of the cover and extending generally longitudinally of the tube throughout its length, the reformable wire sufficiently stout to retain the hose in a serpentine shape.
