Combination fire extinguisher and tire sealer

A method of sealing and inflating a vehicle's pneumatic tire from a fire extinguisher charged with a special combination fire-extinguishing and tire-sealing composition, comprising the steps of:

• (1) detaching a removable nozzle from said fire extinguisher;
• (2) attaching to said fire extinguisher, in place of the detached nozzle, a coupling fitted to one end of a hose of a conduit assembly;
• (3) moving the vehicle so as to locate suspected leakage at the bottom of said tire;
• (4) attaching a tire valve coupling, fitted to the other end of the hose of the conduit assembly, to a valve of a pneumatic tire to be sealed and inflated;
• (5) actuating the fire extinguisher to dispense the special combination fire-extinguisher and tire-sealing composition through the conduit assembly and tire valve into the tire;
• (6) detaching the conduit assembly from the tire valve;
• and
• (7) moving the vehicle so as to disperse the composition within the tire and to generate heat therein, thereby accelerating the sealing action of said special combination fire-extinguisher and fire-sealing composition and further increasing pressure in the tire, and thus enabling the vehicle to be driven to a service station.

A combination fire extinguisher and tire sealer comprising:

• (a) fire extinguisher container;
• (b) a combinat on fire-extinguishing and tire-sealing composition within said fire extinguisher container, sail composition being capable of extinguishing a fire and sealing a pneumatic tire when injected into the interior of said tire;
• (c) a nozzle means to dispense said composition from said fire extinguisher container in a manner to extinguish fires;
• and
• (d) a tire sealer conduit means adapted to connect said fire extinguisher container and a valve of said pneumatic tire at opposite ends thereof, enabling said composition to be dispensed from said container and injected into the interior of said pneumatic tire in a manner to seal the tire against loss of pressure;
• said fire extinguishing container including a discharge valve adapted to remain normally closed so as to contain said composition within said container, and associated with said discharge valve, valve actuating means adapted to open said valve in response to manual pressure applied to said actuating means by a user, and thus cause said composition to be expelled from said container through said nozzle means, said valve actuating means comprising a hinged discharge lever adapted to open said discharge valve when said discharge lever is manually depressed toward said container to a discharge position, and further comprising a hinged carrying handle adapted to have a storage position in which it is positioned so as to lock said discharge lever against moving to its discharge position, and a carrying position in which it is positioned so as to allow said discharge lever to be depressed to its discharge position;
• and
• said combination fire-extinguishing and tire-sealing composition comprising an expellant having the capability of expelling said composition from said container in the form of a pressurized gaseous mixture, enabling injection of the sealant of said composition into said pneumatic tire through said conduit means so as to simultaneously seal and inflate the tire.

• (b) a combination fire-extinguishing and tire-sealing composition within said fire extinguisher container, said composition being capable of extinguishing a fire and sealing a pneumatic tire when injected into the interior of said tire;
• (c) a nozzle means to dispense said composition from said fire extinguisher container in a manner to extinguish fires;

• said fire extinguishing container including a discharge valve adapted to remain normally closed so as to contain said composition within said container, and associated with said discharge valve, valve actuating means adapted to open said valve in response to manual pressure applied to said actuating means by a user, and thus cause said composition to be expelled from said container through said nozzle means;
• and wherein said container is made cylindrical in shape;
• said discharge valve comprises a hollow plunger stem, extending outward from an end of said container, adapted to open said discharge valve when said plunger stem is depressed toward said container;
• wherein said nozzle means comprises a coaxial nozzle having a central passageway adapted to fit over said plunger stem;
• and wherein said valve actuating means comprises a peripheral flange portion configured concentrically as part of said nozzle, whereby pressure applied by fingers of a user onto said flange portion, depressing said plunger stem, causes said valve to open and thus expel said composition from said container through said stem and said nozzle in a manner to extinguish fires;
• and said combination fire-extinguishing and tire-sealing composition comprising an expellant having the capability of expelling said composition from said container in the form of a pressurized gaseous mixture, enabling injection of the sealant of said composition into said pneumatic tire through said conduit means so as to simultaneously seal and inflate the tire.
