Abstract
Abstract A reformable, shape retentive hose having a precured tube located in a hose sidewall, and a reformable rod inserted in the precured tube. A method for making hose by placing at least one precured tube in the sidewall of a hose during the time that the hose sidewall is formed, curing the hose assembly with the precured tube in the sidewall, and inserting a reformable rod in a portion of the precured tube.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
54 words
In a formable hose of the cured elastomeric type having a tube, a cover and a reinforcement that together characterize a sidewall of the hose, the improvement comprising: at least one precured elastomeric tube located in the sidewall and longitudinally oriented with the hose; and a reformable rod disposed in the precured elastomeric tube.
Claim 2
Dependent Claim
54 words
In a formable hose of the cured elastomeric type having a tube, a cover and a reinforcement that together characterize a sidewall of the hose, the improvement comprising: at least one precured elastomeric tube located in the sidewall and longitudinally oriented with the hose; and a reformable rod disposed in the precured elastomeric tube.
Claim 3
Dependent Claim
36 words
The formable hose as claimed in claim 1, of which the sidewall successively comprises the tube, a fibrous reinforcement and the cover, and wherein the precured elastomeric tube is located between the tube and fibrous reinforcement.
Claim 4
Dependent Claim
23 words
The formable hose as claimed in claim 2, which further includes a helical wire means for inhibiting kinking when the hose is bent.
Claim 5
Dependent Claim
36 words
The formable hose as claimed in claim 1 of which the sidewall successively comprises the tube, a fibrous reinforcement and the cover and wherein the precured elastomeric tube is located between the fibrous reinforcement and cover.
Claim 6
Dependent Claim
23 words
The formable hose as claimed in claim 4, which further includes a helical wire means for inhibiting kinking when the hose is bent.
Claim 7
Dependent Claim
47 words
The formable hose as claimed in claim 1, of which the sidewall successively comprises the tube, a fibrous reinforcement, the cover and a strip of fibrous reinforcement longitudinally oriented with the hose, and wherein the precured tube is located between the cover and strip of fibrous reinforcement.
Claim 8
Dependent Claim
23 words
The formable hose as claimed in claim 6, which further includes a helical wire means for inhibiting kinking when the hose is bent.
Claim 9
Dependent Claim
43 words
The formable hose as claimed in claim 1, of which the sidewall successively comprises the tube, a fibrous reinforcement and cover, and wherein the sidewall is corrugated intermediate cuff ends of the hose and the reformable rod extends substantially between the cuff ends.
Claim 10
Dependent Claim
41 words
A hose as claimed in claim 8 wherein the precured tube extends an entire length of the cured hose, and is partially flattened at each cuff end, and is partially spread apart and straightened juxtaposed the reformable rod and corrugated sidewall.
Claim 11
Dependent Claim
37 words
The formable hose as claimed in claim 8 wherein the precured tube is located between the tube and fibrous reinforcement, and the hose further includes a helical wire means for inhibiting kinking when the hose is bent.
Claim 12
Dependent Claim
18 words
The formable hose as claimed in claim 9 wherein the helical wire is located in the hose sidewall.
Claim 13
Dependent Claim
20 words
The formable hose as claimed in claim 9 wherein the helical wire is located in a bore of the hose.
Claim 14
Dependent Claim
89 words
In a formable, shape retentive hose of the cured elastomeric type with a tube having a bore, a reinforcement and a cover, which together characterize a sidewall of a hose that is corrugated between cuff ends, the improvement comprising: at least one precured tube located in the sidewall and longitudinally oriented and extending an entire length of the hose; a reformable rod disposed and free to slide in the precured elastomeric tube intermediate the cuff ends; and a helical wire means for inhibiting kinking when the hose is bent.
Claim 15
Dependent Claim
89 words
In a formable, shape retentive hose of the cured elastomeric type with a tube having a bore, a reinforcement and a cover, which together characterize a sidewall of a hose that is corrugated between cuff ends, the improvement comprising: at least one precured tube located in the sidewall and longitudinally oriented and extending an entire length of the hose; a reformable rod disposed and free to slide in the precured elastomeric tube intermediate the cuff ends; and a helical wire means for inhibiting kinking when the hose is bent.
Claim 16
Dependent Claim
36 words
The formable hose as claimed in claim 12, of which the sidewall successively comprises the tube, a fibrous reinforcement and the cover, and wherein the precured elastomeric tube is located between the tube and fibrous reinforcement.
Claim 17
Dependent Claim
19 words
The formable hose as claimed in claim 13 wherein the helical wire means is located in the hose bore.
Claim 18
Dependent Claim
19 words
The formable hose as claimed in claim 12 wherein the hose sidewall is thicker juxtaposed the precured elastomeric tube.
Claim 19
Dependent Claim
32 words
The formable hose as claimed in claim 12 wherein there are at least two longitudinally oriented precured tubes located in the sidewall and a reformable rod is disposed in each precured tube.
Claim 20
Dependent Claim
35 words
The hose as claimed in claim 12 wherein the hose with the precured tube in the sidewall is pressure cured in a mold and after which the reformable rod is inserted in the precured tube.
Claim 21
Dependent Claim
37 words
The hose as claimed in claim 17 wherein the precured hose follows a corrugated path in the sidewall after the hose is cured and a substantially straighter path after the rod is inserted in the precured tube.
