Abstract

The present apparatus for starting and fanning a fire, for example in a fireplace, is hand operated and combines in a common handle housing a source of fuel for providing an ignition flame and a power source as well as a fan for blowing air into the fire. The fan is driven by the power source such as a battery. The control for the apparatus is so arranged that the supply of fuel gas and an ignition spark occur substantially simultaneously, whereby the fan is preferably operating on "low". Once the fire has started the fuel gas supply is stopped and the fan may be operated on "high" by an electric motor which may be driven by said battery or through an adapter from a power outlet.

Claims

1. An apparatus for igniting and fanning a fire, comprising hollow housing means, fuel gas nozzle means in said hollow housing means, battery operated fan means in said hollow housing means, ignition means arranged to ignite fuel gas emerging from said fuel gas nozzle means, manual control means arranged in said hollow housing means and operatively connected to said ignition means, and to said fan means for activating the just mentioned components for a predetermined cooperation wherein said ignition means comprise piezoelectric crystal means (11) located substantially centrally in said housing and operable through force applying means responsive to said control means, said manual control means including gas closure valve means (9) operatively interposed in the gas supply line (22) between said fuel gas nozzle means (8) and a gas supply source (6), said manual control means further including two position switch means (10) operatively interposed between an electric motor of said fan means and a source of power (7) for said fan means, said manual control means further including a mechanical actuating member (12) operatively connected to said piezo-electric crystal means (11), to said valve means (9), and to said two position switch means (10), said apparatus further comprising mechanical air intake means (4) for adjusting the air supply to said battery operated fan means (3).

2. The apparatus of claim 1, wherein said control means first provide for a fuel supply to said nozzle means, then provide for an ignition spark to said nozzle means, and then provide for the operation of said fan means.

3. The apparatus of claim 2, wherein said control means provide a low fan operation substantially simultaneously with said ignition spark.

4. The apparatus of claim 1, wherein said ignition means comprise piezo-electric means, conductor means connected to said piezo-electric means and forming a spark gap with said fuel gas nozzle means, said control means comprising a mechanical connection to said piezo-electric means for applying a spark producing force to said piezo-electric means.

5. The apparatus of claim 4, wherein said housing means comprise a pipe extension wherein said nozzle means and said conductor means are operatively located.

6. The apparatus of claim 5, wherein said pipe extension has an open end, said ignition means being operatively held in said pipe extension adjacent said open end, wherein said fuel gas nozzle means are also located in said pipe means for cooperation with said ignition means, a first cavity in said housing means for holding an electrical power source, a second cavity in said housing means for holding fuel gas supply means, conduit means operatively connecting said fuel gas supply means to said nozzle means through said control means, a third cavity in said housing means, said fan means being located in said third cavity, said control means operatively connecting said fan means to said electric power source.

7. The apparatus of claim 1, wherein said housing means comprise a pipe extension having a shaped tip wherein said nozzle means are located, said tip including a flattened funnel shaped guide means for enhancing the mixing of air with the combustion flame, said guide means also preventing the exit of the flame out of said tip.

8. The apparatus of claim 1, further comprising pipe section means operatively connected to said housing means forming a handle, said battery operated fan means being arranged in said housing means adjacent to the interface between the pipe section and the housing, said fan means including electric motor means and a radial blower, said housing means further comprising a closure cap for closing a cavity adapted to receive a liquid gas cartridge and a further cavity adapted to receive electrical dry cells.

9. The apparatus of claim 1, wherein said housing means comprise air access port means operatively located for cooperation with said battery operated fan means, and means for varying the opening area of said air access port means, said varying means being operatively connected to said control means.

10. The apparatus of claim 1, wherein said control means comprise a single pressure-shifting button for actuating said piezo-electric crystal element, said valve means, and said switch means in common.

11. The apparatus of claim 1, wherein said control means comprise individual actuating elements all of which are arranged in a common area for actuation by one hand.

12. The apparatus of claim 1, wherein said control means for operating said valve means comprise automatic reset means for closing the valve means and thus the gas supply when the respective control means are not actuated.

13. The apparatus of claim 1, wherein said reset means comprise a safety button which must be actuated simultaneously with the control means for the valve means.

14. The apparatus of claim 1, further comprising electrical adapter means for driving said battery operated fan means from a regular power supply outlet.
