Abstract: The invention employs a blower of the type used by commercial landscapers. The device has an engine mounted on a frame. Shoulder straps attached to the frame allow the user to wear the device on his back leaving the hands of the operator free to operate other tools such as a chain saw or perform other tasks. Also, wearing the device on the back makes it easier to transport the device over long distances to the source of the fire or backfire to be started. The device's blower generates a stream of air at high speeds. This stream of air can be used to feed a fire when the air is directed at a fire. When used to extinguish a fire, air from the blower is tapped from a point 180 degrees removed from the blower output and mixed with exhaust from the engine. This mixture is diverted through a Y-shaped valve into the airstream coming out of the blower. When the device is used to start backfires a fire is started.

Abstract: This apparatus is designed for automotive vehicles, and enables the employment of a vehicle's engine exhaust to be used to put out fires. Primarily, it consists of a flexible hose with a nozzle or cone at one end for the exhaust gas of the engine to be directed onto a fire, and the other end of the hose is secured to a selector valve attached to the tail pipe portion of the engine's exhaust system, so as to divert the exhaust gas for fire fighting. The apparatus includes a water spray collar at the rear of the nozzle which is supplied from a water source to cool the nozzle, and the nozzle includes a handle for a user to hold it.

Abstract: The combination machine is used both as a fire extinguisher and an air blower. Primarily, it consists of a back-pack or other type unit having an internal combustion engine powering a blower. It includes one hose coupled to a pivotal exhaust pipe cover and to the air inlet of the blower, and the hose pipes exhaust gas into the blower when such gas is needed to extinguish a fire. A second hose is provided and is coupled to the blower at one end and is secured to a sleeve fastened to an air cooled cone or nozzle which is used to blow air or exhaust gas, whenever needed.
