Abstract
A safety hose having a stretchable elastomeric tube and cover that sandwich a twined reinforcement that exhibits a circumferential reinforcement component and a weaker longitudinal reinforcement component that breaks when the hose is stretched.
Claims6
In a hose of the type having an elastomeric tube, a twined reinforcement encircling the tube and an elastomeric cover encircling the tube and reinforcement, the improvement comprising:
- a knit reinforcement comprising intermittent leads of a first yarn and a second, tensionally weaker yarn alternatively knitted together with knit stitched loops that each have a helically oriented component and a longitudinally oriented component in relation to the tube and wherein a cumulative tensile strength of the longitudinally oriented loop components is substantially less than a cumulative tensile strength of the helically oriented loop components such that some of the loops of the second yarn define a means to break and permit substantial elongation of the hose without tube rupture.
In a hose of the type having an elastomeric tube, a twined reinforcement encircling the tube and an elastomeric cover encircling the tube and reinforcement, the improvement comprising:
- a twined textile reinforcement having a circumferentially oriented reinforcement component and a longitudinally oriented reinforcement component wherein a cumulative tensile strength of the longitudinally oriented component is substantially less than a cumulative tensile strength of the helically oriented component such that parts of the reinforcement of the longitudinally oriented component define a means to break and permit substantial elongation of the hose without tube rupture.
