  • Patent number: 5425352
    Abstract: A portable and nestable grill having two generally conical shaped sections forming inverted conical housings removably joined together at the smaller ends forming a midsection or waist of reduced diameter. The upper conical shaped housing defines an upper grilling section for supporting a cooking grate near the upper end and a means for supporting charcoal or other solid fuel at the lower end of the upper housing forming the waist section. The lower conical shaped housing defines a charcoal starter/ash catcher base section. A plurality of apertures are sized, shaped, and positioned to provide sufficient draft to create a venturi effect at the position of the fuel support means to provide fast pre-ignition of the solid charcoal fuel and superior convective heat transfer for cooking. The upper housing may be detached from the lower housing and the lower housing inverted and nested within the larger upper housing for transporting and storage.
