Abstract
This disclosure relates to a hose including a tube and a braided wire reinforcement covering the tube. The wire braid includes a plurality of interwoven strands of wires, and each strand includes a plurality of wires having a uniform tension and a twist of from approximately one turn for each two and one-half to three inches. Further, each of the wires of the strand is preformed to produce a helical tension spring configuration, and the strands are braided under a relatively high tension. The hose is made by a method including the steps of preformng wires to produce the helical tension spring configuration, combining a plurality of such wires under a uniform tension and twisting such wires to form strands, and braiding a plurality of such strands under high tension.
Claims15
A wire braid for a reinforced hose, comprising a plurality of strands of metal wire, said strands being interwoven to form a braid, each of said strands including a plurality of wires which are separately preformed by being bent transversely of the wire axis under tension prior to being combined with other wires to form said strand, and each of said wires having a coiled or helical configuration when it is untensioned.
A wire braid for a reinforced hose, comprising a plurality of strands of preformed metal wire interwoven to form a hose braid, the wires of each of said strands being substantially uniformly and regularly arranged and having a twist of approximately one turn over a length of at least two and one-half inches, and said strands having a relatively high braiding tension of at least approximately eighteen pounds.
A wire braid for a reinforced hose comprising a plurality of strands of metal wire, each of said wires being preformed to a coiled spring configuration when not under tension, the wires of said strands having a uniform braiding tension of between approximately eighteen pounds and twenty-five pounds.
A hose braid comprising a plurality of strands of metal wires, each of said strands comprising a plurality of steel wires joined together in a twisted configuration and having substantially equal longitudinal tension, said plurality of strands being interwoven on a braiding machine to form a hose braid, each of said wires further having a preform to the shape of a coiled spring-like helical coil therein when separate from said strand and in an untensioned condition, said strands receiving said preform while moving in said braiding machine.
A reinforced hose comprising a tube, at least one layer of metal wire reinforcement on said tube, said wire reinforcement being formed by a plurality of strands of wire woven in a braid and having a braiding tension of between approximately eighteen pounds and twenty-five pounds, each of said strands including a plurality of tensioned wires and having a twist of between approximately one turn per two and one-half to three inches, and each of said wires having a coiled spring-like configuration when it is untensioned.
