  • Patent number: 4422435
    Abstract: A charcoal briquette igniter for use with outdoor grills includes a pressurized fuel gas container and a burner which has a cage that surrounds the orifices to which the fuel gas issues from the burner. An airtight conduit innerconnects the burner and container so that the admixture of air and fuel transpires after the fuel gas has been discharged from the orifices, the cage under such circumstances being adapted to support the briquettes spacedly apart from the orifices and to define a compartment in which the air and combustible fuel gases mix and burn. The fuel container of the igniter is supported by a hanger that is in turn suspended from the wall of the grill brazier, the hanger being adapted to underlie a valve component that is secured to the container and to support the container at the side of the grill through its connection with the valve component.
