Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A longitudinally resilient flexible hose comprising: a fluid conducting tubular member; a covering around the exterior periphery of said tubular member including; a metallic wire element extending in spaced helical convolutions around the outer periphery of said tubular member at a pitch of at least about 70*; and a sheath means of yarns braided at a pitch of from about 52* to 57* over the said convolutions of the metallic wire elements, the inner periphery of said sheath means being bonded to the exterior periphery of said tubular member.
Claim 2
Dependent Claim
89 words
A longitudinally resilient flexible hose comprising: a fluid conducting tubular member; a covering around the exterior periphery of said tubular member including; a metallic wire element extending in spaced helical convolutions around the outer periphery of said tubular member at a pitch of at least about 70*; and a sheath means of yarns braided at a pitch of from about 52* to 57* over the said convolutions of the metallic wire elements, the inner periphery of said sheath means being bonded to the exterior periphery of said tubular member.
Claim 3
Dependent Claim
27 words
A longitudinally resilient flexible hose of claim 1 including a plurality of metallic wires braided in an open braid around the outer periphery of the tubular member.
