Abstract
A fire extinguisher system using liquid-ballast tires of a vehicle, such as a tractor or log skidder. The tire has a fire retardant liquid, and it may be water, and it has several valves spaced therearound. A gas supply can be attached to one of the valves to force the liquid from the tire, and a hose can be attached to another one of the valves for directing the evacuating liquid from the tire and toward the fire.
Claims5
A method of providing fire-fighting water in a vehicle having inflatable tires, comprising the steps of arranging a fluid-inflatable vehicle tire with several quick-connect connector valves equally spaced around the tire for introducing and removing fluid relative to the tire, inflating the tire with a fire retarding liquid, connecting a first conduit having a quick-connect connector to one of said valves in the lowest position on the tire when the tire is motionless and it is desired to remove the liquid from the tire to fight a fire, connecting a second conduit having a quick-connect connector and a pressurized supply of a fluid to one of said valves in an upper position on the tire and releasing the pressurized fluid to the interior of the tire and thereby force the liquid out of the tire through said lowest one of said valves and said first conduit.
A fire extinguisher system using liquid-ballast tires, comprising a vehicle tire having a fire retarding liquid therein, at least several identical two-way-flow and quick-connect valves affixed to said tire at locations equally spaced therearound, and a flexible liquid conduit having a quick-connect valve connector connected with the one of said valves in the lowest position when said tire is motionless, for removing the liquid from said tire, a container of a pressurized supply of a gas and having a conduit with a quick-connect valve connector connected with one of said valves in an upper position relative to said lowest valve and when said tire is motionless, for introducing the gas under pressure and into said tire and forcing the liquid from said tire.
