Abstract: Liquid fuel, such as gasoline, kerosene, or naptha, is sprayed through a tube into a centrifugal blower. The fuel supply tube extends concentrically through a central collar on the blower casing at one axial side of the blower, and ambient air is supplied through this collar into the blower. Manually adjustable valves control the supply of liquid fuel and air, respectively. The blower casing has an outlet for vaporized fuel at the same side of the blower as the central collar. An electrical heating element on the casing keeps the fuel vaporized inside. An electric motor which drives the blower is bolted to the opposite side of the casing. A holder encircles the motor outside the blower casing, and a handle connects this holder to the casing. Support legs extend down from the blower casing and the motor holder.
