Non-stretch breakaway hose particularly for fuel dispenser
First Claim
1. A system for dispensing a fluid from a first tank into a second tank, one of the tanks being attached to a vehicle, the system comprising a flexible, stretchable, resilient delivery hose, a first end of the delivery hose being connected to the first tank and a second end of the delivery hose being attached to a nozzle adapted to dispense the fluid into the second tank;
- first and second fittings on the hose, the fittings being separated by at least six feet, and a flexible tension element between the fittings, the tension element substantially eliminating stretching of the delivery hose between the fittings.

Abstract
A system for dispensing a fluid from a first tank into a second tank, in which one of the tanks is attached to a vehicle. The system comprises a flexible, stretchable, resilient delivery hose, a first end of the delivery hose being connected to the first tank and a second end of the delivery hose being attached to a nozzle adapted to dispense the fluid into the second tank. A flexible tension element is provided between first and second fittings on the hose, the fittings being separated by at least six feet (two meters), the tension element substantially eliminating stretching of the delivery hose between the fittings. The tension element substantially reduces damage to the hose and to surrounding persons and objects when the hose is pulled and released as in a drive-away from a gasoline dispenser.

- 24. A method for preventing damage to and by a flexible, stretchable, resilient liquid delivery hose used for dispensing fuel from a fuel dispenser structure through a manually operated nozzle to a vehicle fuel tank, the hose comprising a breakaway coupling having a nominal separation force of from one hundred to four hundred pounds, a section of the hose between the breakaway coupling and either the dispenser structure or the nozzle having a length of at least six feet, the method comprising attaching a flexible tension element between fittings at the ends of the section of the hose, the tension element reducing stretching of the delivery hose between the fittings at any tension less than the nominal separation force of the breakaway coupling to less than ten percent of the stretching of the delivery hose without the tension element.
- 27. An improved hose adapted for use in a fuel delivery system, the hose comprising an elastomeric body, the hose having a length of at least six feet, the elastomeric body stretching to more than one hundred ten percent of its length when subjected to a two-hundred-fifty pound pull, the hose having fittings at its ends, the hose further including a linear tension element, the tension element extending the length of the hose, the tension element substantially preventing stretching of the hose when subjected to a two-hundred-fifty pound pull.
