Abstract
Abstract A contour formable hose with a reformable insert disposed in the hose duct, the insert with at least two spaced ring means that engage an internal annular portion of the hose interior wall so that a ring means is located near each end portion of the hose. A rod bias means is interpositioned between and attached to the ring means and the rod bias means is capable of being yielded to a new bias shape.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
In a corrugated type hose with cuff ends, a collapse resistant reinforcement, and an internal wall, the improvement comprising: a reformable insert disposed in the hose and comprising at least two generally coaxial ring means, each having an outside diameter and yield point, the ring means axially spaced in relation to the hose with a ring means engaging and biased against annular portions of the internal wall of the hose at each cuff end; and a flexible and substantially uncoiled rod means having a yield point and oriented generally axially with the hose and attached to the spaced ring means, the rod means capable of and for being deformed past its yield point to a new retentive shape.
Claim 2
Dependent Claim
118 words
In a corrugated type hose with cuff ends, a collapse resistant reinforcement, and an internal wall, the improvement comprising: a reformable insert disposed in the hose and comprising at least two generally coaxial ring means, each having an outside diameter and yield point, the ring means axially spaced in relation to the hose with a ring means engaging and biased against annular portions of the internal wall of the hose at each cuff end; and a flexible and substantially uncoiled rod means having a yield point and oriented generally axially with the hose and attached to the spaced ring means, the rod means capable of and for being deformed past its yield point to a new retentive shape.
Claim 3
Dependent Claim
31 words
The hose as claimed in claim 1 wherein ring means spaced intermediate of those ring means at the cuffs are smaller than those ring means spaced intermediate of the cuff ends.
