  • Patent number: 4413515
    Abstract: A support adjacent to the lower end of the pedestal for a barbecue engages under a bottom edge portion of the barbecue fuel tank such that the tank tends to tilt away from the pedestal by gravity. A gauge member connects to the top of the tank and passes through an opening in the pedestal to protrude out the opposite side. A spring provides a force opposing the tendency of the tank to tilt so that the degree of tilt is determined by the weight of the tank which in turn is determined by the amount of fuel in the tank. Thus, by observing the amount by which the gauge member protrudes through the opening in the pedestal, there is provided an indication of the fuel level in the tank.
