Patent number: 6058830Abstract: A cooking apparatus enables a user to cook (boiling, steaming or frying). The apparatus includes a burner having a base that is specially shaped to cradle a pot. An upper ring extends above the support surface of the burner for engaging the sidewall of the pot should the pot be tipped inadvertently. A table removably attaches to the burner frame, preferably at the upper ring. The burner can include an upper ring member that is supported above the bottom of the pot and a lower ring member that engages an underlying supporting ground surface. Alternatively, the burner frame has a plurality of circumferentially spaced radially extending legs. Struts are shaped and cradle the bottom of the pot and its sidewall respectively.Type: GrantFiled: October 25, 1999Date of Patent: May 9, 2000Assignee: Metal Fusion, Inc.Inventor: Norman R. Bourgeois

Patent number: 6050257Abstract: An open grill assembly, with a radiant heating sheet, can be assembled together into a rigid grill, with rods forming a frame supporting the radiant sheet and the grid in a spaced apart relationship. The components can be disassembled into a compact bundle, preferably a flat bundle. When assembled, in a preferred embodiment, the radiant heating sheet is adapted to rest on the top of the burner, so that the rods forming the frame need not touch the ground, allowing a single, economical design to be used with most, and perhaps all, commercially available burners. In operation, the burner heats the radiant heating sheet and radiant heat from the sheet cooks food on the grid.Type: GrantFiled: January 11, 1999Date of Patent: April 18, 2000Assignee: Bondco, Inc.Inventor: Joseph N. Bond

Patent number: 6038964Abstract: A convection based cooking apparatus with an insulating baffle to provide improved air-flow and isolation between a cooking chamber and a heating chamber. The heating chamber and the cooking chamber are positioned side by side, and separated by the insulating baffle. The insulating baffle is hollow for holding a liquid and includes an opening for emitting steam. An air passage exists between the heating chamber and the cooking chamber, in such a way that, heated air passes through the passage, flows over the insulating baffle to combine with the steam, and then into the cooking chamber. The air passage is located near the top of the heating chamber and the cooking chamber. As the air passes over the insulating baffle, the air is diffused throughout the cooking chamber and thereby uniformly distributed across a cooking surface within the cooking chamber.Type: GrantFiled: May 22, 1998Date of Patent: March 21, 2000Inventor: Jimmy A. Sikes

Patent number: 6038965Abstract: A portable barbecue grill apparatus has multiple functions including barbecuing, baking, roasting, and pan broiling, some of which can be accomplished simultaneously on joined cooking elements. The grill apparatus can have an extendable rear lid having a rotisserie attached to a base. Alternatively, a pair of slotted side plates attached to the lid and covered by a heat shield can permit the spacing of the spit from the burner in the lid according to the size of the rotating fool. The lid and base each contain heating elements energized by one or two portable propane tanks.Type: GrantFiled: September 22, 1999Date of Patent: March 21, 2000Inventor: Robert J. Thorndyke

Patent number: 6016797Abstract: A barbecue grill modified by a smoke directing sleeve to convert the grill into a food smoker in which there is a sleeve of rolled form adapted to be unrolled to fit on the grill to position a food supporting grill spaced from the source of heat, and providing handles on the sleeve in position to allow removal of the sleeve to free up access to the fuel in the cooking grill. The rolled form constitutes a kit and the kit is adapted to extend the utility of the barbecue grill for food smoking treatment.Type: GrantFiled: February 14, 1997Date of Patent: January 25, 2000Inventor: Frank L. Nowicke, Jr.

Patent number: 6012381Abstract: A convection meat cooker characterized by an elongated, cylindrical cooker tank which, in a preferred embodiment, is provided on a portable cooker frame and includes concentric outer, middle and inner shells. The inner shell defines an interior cooking chamber which is hermetically sealed by a door hinged to the outer shell at one end of the cooker tank and a cylindrical, annular heat chamber is defined between the middle and inner shells throughout the length of the cooker tank. Insulation is typically provided between the middle and outer shells of the cooker tank. A heat entrance port extends from the middle shell and receives a propane-fueled burner for heating the cylindrical heat chamber and a heat exit port vents excess heat from the annular heat chamber. An open water container may be removably attached to the cooker frame and pressure vent piping provided in fluid communication with the cooking chamber is immersed in water provided in the water container.Type: GrantFiled: July 1, 1999Date of Patent: January 11, 2000Inventor: Clifford W. Hawn
