Abstract
Abstract A length of hose made of a flexible and weather-proof material having high elasticity e.g., a suitable synthetic resin, or plastics or a co-polymer of ethylene vinyl acetate resin, having a plurality of incisions formed in the wall of the hose from inside to outside at proper portion thereof, and comprising a strengthening means such as a longitudinal cross shaped pressback means made of polyethylene or a co-polymer of acrylo nitrile ethylene or ethylene vinyl acetate inserted into the hose; the hose may instead be provided with longitudinal stiffening ribs on the surface thereof; longer lengths of the hose may be formed by joining shorter lengths of the hose by means of adaptors.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
In a flexible hose made of a resilient material and of the type provided with incisions in the tube wall which are leakproof when the hose is not in use but resiliently open up when a liquid under pressure is pumped therethrough to give out jets of the liquid, the improvement being in that the hose comprises stiffening means disposed longitudinally of the hose, said stiffening means comprising elongated press-back means inserted into the hose, extending substantially the length of the hose, the press-back means including in cross-section radially projecting members so as to provide mechanical strength to the hose, and to resist the hose being fully collapsed under a load so as to maintain continuity of supply of the liquid.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
61 words
The hose as claimed in claim 1, which further includes interconnecting tubular means adapted to be inserted into the ends of hose sections to connect serially shorter lengths of the hose to form a longer length thereof, and wherein each said tubular means is adapted to prevent an adjacent press-back means from being conveyed away by pressure liquid in the hose.
