Patent number: 6161534Abstract: Backyard type gas grills are made suitable for use with solid fuels such as charcoal by removing existing passive radiant heat material such as lava rocks and inserting an apparatus comprising supports (50) and perforated fuel basket (40). The unique design of the invention allows for its implementation in a majority of gas grills on the market by permitting the supports (50), which rest on at least a gas burner, to be positioned and fastened to the fuel basket (40) anywhere and in various directions with respect to the fuel basket (40). Locking means (56) prevent separation of the supports from the fuel basket. By locking the supports (50) to the fuel basket (40), the supports add structural integrity to the fuel basket and prevent the basket from warping and torquing due to repeated exposure to extreme temperature differentials.Type: GrantFiled: July 23, 1997Date of Patent: December 19, 2000Inventor: Leonard Kronman

Patent number: 6158330Abstract: A broiler pan cooking grid for a barbecue grill that catches and/or routes grease drippings, as well as permitting convection of heated air through the structure. The grid may be used with conventional horizontal barbecue grills or with grills having a vertical hearth or firebox. The grid assembly preferably comprises sheet metal having cutouts stamped in the upper surface, e.g., elongated slots or perforations, and a series of elongated troughs stamped in the lower surface. The elongated troughs of the lower layer route grease drippings to a grease box or tray that is disposed along the front edge of the cooking grid assembly. As series of stiffening rods are sandwiched between the layers to provide rigidity when using thin sheet metal. Preferably, the grid assembly is supported in an inclined position by the barbecue grill, but the lower sheet metal stamping may itself be formed to contain the grease or to effect the flow of grease to a grease box.Type: GrantFiled: November 5, 1999Date of Patent: December 12, 2000Inventor: Alphonso G.

Patent number: 5974954Abstract: A cooking grate for a grill, such as a barbecue grill, is comprised of a plurality of generally elongate rail members assembled in a nesting relationship to form a first and second cooking surface. The first cooking surface is formed by a generally flat surface on each of the rail members, the flat surfaces abutting to form a substantially smooth surface, with a plurality of elongate apertures therein through which juices produced by cooking food may flow. Each rail member has a gutter along its length which underlies approximately half of each of the apertures for catching a portion of the juices and diverting it from the heat source below. The grate may be reversed and the gutters form the second cooking surface which is similar to a conventional grate surface.Type: GrantFiled: August 25, 1998Date of Patent: November 2, 1999Assignee: Empire Comfort Systems, Inc.Inventors: Donald P. Rigney, Lloyd Maschhoff
