Abstract

A system to repair a hose made from deformable material includes an elongated container for holding a liquid heated sufficiently for softening the hose. A heater can be positioned in the container. A plurality of restraining members can be positioned to retain the hose immersed in the liquid within the container. A gas supply is used to pressurize the hose prior to immersion, and a support is provided for holding the hose before and after immersion. A method includes filling an elongated container with a heated liquid and pressurizing the hose with a gas. The pressurized hose is immersed in the liquid and maintained immersed by retaining members to soften the hose. The hose is removed from the liquid, depressurized and allowed to cool.

First claim

What is claimed is:

1. A system to repair a hose made from deformable material, comprising:
an elongated container for holding a liquid;
a heater system operable for heating the liquid disposed in said elongated container sufficiently for softening said deformable material for use in the container to a predetermined temperature;
a plurality of restraining members capable of being spaced apart in said elongated container, each of said plurality of restraining members having an engagement surface capable of engaging an exterior of the hose and maintaining at least a portion of the hose immersed in the liquid within said elongated container;
an air supply capable of pressurizing the hose; and
a support capable of holding the hose after positioning the hose in said elongated container.

2. The system of claim 1 , further comprising:
an initial hose storage device capable of storing the hose and positioned to provide the hose to said elongated container; and
a final hose storage device capable of storing the hose and positioned to receive the hose from said support.

3. The system of claim 2 , wherein said initial hose storage device and said final hose storage device are capable of moving the hose through said elongated container and said support for creating a continuous repair process.

4. The system of claim 1 , wherein said heater system comprises:
a conduit joined to a first end of said elongated container and a second end of said elongated container for transmitting liquid from said first end to said second end;
a pump joined to said conduit for moving the liquid; and
a heater joined to said conduit to for heating the liquid.

5. The system of claim 1 , wherein said plurality of restraining members are removably insertable into said container.

6. The system of claim 5 , further comprising at least one cover joined to said elongated container, said restraining members being joined to said cover wherein said cover is operable to urge said plurality of restraining members downwardly in said liquid for submerging the hose in said liquid.

7. The system of claim 6 , further comprising a securing method including at least one of a hinge, a clamp and both, disposed between said cover and said elongated container, whereby said cover is securable in a closed position with respect to said elongated container by said securing method.

8. The system of claim 5 , wherein said plurality of restraining members have a weight and density sufficient to immerse the hose in said liquid when the hose is pressurized.

9. The system of claim 8 , wherein said restraining member has a slot formed therein capable of guiding the hose upwardly towards said restraining member engagement surface due to buoyant force.

10. The system of claim 1 , wherein said restraining member engagement surface comprises at least one semi-circular surface portion having an arc of less than 180 degrees.
