Externally Accessible Operator Fires Charge Within Flame Enclosure Patents (Class 431/270)
  • Patent number: 9746182
    Abstract: A home cooking appliance having an electrode chamber for a burner assembly is provided. The home cooking appliance includes a burner rail, maintop surface, burner assembly including a burner electrode, igniter box below the burner rail and maintop surface, and an electrode chamber on the burner rail. The electrode chamber includes a body having a cavity and a first opening at a first end of the body, wherein a portion of the burner electrode is disposed in the cavity, an electrical contact surface in the cavity that engages and electrically connects the electrical contact surface to the portion of the burner electrode, and an electrical connector at a second end of the body, the electrical connector being electrically connected to the electrical contact surface and to the igniter box, thereby electrically connecting the igniter box to the portion of the burner electrode.

  • Patent number: 8845325
    Abstract: An apparatus for lighting an oxygen candle within a drum and for sealing the drum of an oxygen candle furnace. The apparatus includes a housing member for positioning the ignition assembly on a lid of the drum. The housing member having an upper portion, a lower portion and a borehole extending through the upper and lower portions. An ignition nail is placed in the borehole and housing member is structured to hold prevent the ignition nail from moving laterally, and to automatically align the nail with the oxygen candle within the drum.

  • Publication number: 20090011379
    Abstract: The combustion initiator of this invention preferably includes at least two separate combustible chemical constituents including a fuel cell and an ignition pellet. An igniter has a third combustible material thereon which can be manually caused to move and bring the combustible material into contact with the ignition pellet. The combustible material and ignition pellet are highly reactive with one another so that such contact therebetween causes the ignition pellet to commence combustion. The ignition pellet is adjacent the fuel cell and combusts with sufficient temperature to cause the fuel cell to commence combustion. The fuel cell and ignition pellet are preferably contained within an enclosure which protects the igniter from being manipulated unless the enclosure is first opened. The fuel cell material burns hot enough and long enough to cause combustion of surrounding fuels, such as wood.

  • Patent number: 4583940
    Abstract: An igniter for combustible material includes a support, an element of a material capable of being ignited by friction, a movable friction-strip having a surface portion treated to produce ignition of the element by friction, and a plate secured to the support for holding and guiding the friction-strip is provided with an opening in front of the element. In operation, the friction-strip is pulled through the igniter, which brings the surface portion into frictional contact with the ignitable element and then uncovers the latter when ignited; the flame therefrom is available through the opening in the plate. Because the ignitable element is enclosed in a space between the support and the friction-strip, it is protected against destruction by mechanical impact or by humidity, as well as against accidental ignition due to friction with another body.

  • Patent number: 4197213
    Abstract: A method and apparatus are disclosed for pyrotechnically generating a mixture of at least two gases, substantially in a predetermined ratio, for an extended period of time, with separate pyrotechnic charges generating each component of the resultant mixture. At least one of the pyrotechnic charges is capable of sustained burning at a rate corresponding to the rate of total gas generation, and the remaining charges, not in themselves capable of sustained burning, are caused to sustain ignition by maintaining their burning surface in thermal communication with that of the first charge, so that all charges burn at substantially the same linear rate.
