Abstract
Abstract A portable, compact, gas-fired cooking and barbecuing device for frying and boiling food in conventional cooking utensils, or barbecuing food when a barbecuing attachment is utilized. The device includes a bowl-shaped body having a bottom and a relatively deep, cylindrical side wall. A gas burner assembly is mounted in the bowl-shaped body so that the annular burner of the assembly is positioned toward the bottom of the body to protect it from wind effects. Three circumferentially spaced, radially extending support members connect the burner to the cylindrical side wall of the bowl and serve as supports for cooking utensils in which food is to be fried or boiled. Mounting portions on the other ends of the support members extend above the upper edge of the body for supporting large sized cooking utensils. When the lower cylindrical portion of an annular barbecuing attachment is engaged with the support members of the burner assembly, food items may be barbecued on the barbecuing grill of the attachment. The diameter of the upper portion of the attachment is larger than the side wall of the bowl-shaped body to prevent food drippings from falling onto the bowl side wall.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
249 words
A portable cooking device comprising a bowl-shaped body having a bottom and an upstanding cylindrical side wall, means carried by said body for supporting the body in an upright position on a horizontal surface, an annular burner, means for supplying a combustible mixture of air and gas to said burner, at least one elongated support member connected to said burner and said side wall and supporting said burner in said body generally adjacent to the bottom thereof so that the flame of said burner is protected from the effects of wind during cooking, an annular adapter member having upper and lower ends, said lower end resting on said support member, the diameter of the lower end of said adapter member being greater than the diameter of said burner and less than the diameter of said cylindrical side wall so that an annular gap is defined between said cylindrical side wall and the lower end of said adapter member, and a food supporting grill resting on the upper end of said adapter member, whereby said adapter member is effective to direct heat from said burner upwardly through said food supporting grill to cook food resting thereon and the gap between the cylindrical side wall and the lower end of said adapter member permits air to flow downwardly through said gap when said burner is in operation in countercurrent relation to the upward flow from said burner to cool said cylindrical side wall and to supply additional air to said burner.
Claim 2
Dependent Claim
249 words
A portable cooking device comprising a bowl-shaped body having a bottom and an upstanding cylindrical side wall, means carried by said body for supporting the body in an upright position on a horizontal surface, an annular burner, means for supplying a combustible mixture of air and gas to said burner, at least one elongated support member connected to said burner and said side wall and supporting said burner in said body generally adjacent to the bottom thereof so that the flame of said burner is protected from the effects of wind during cooking, an annular adapter member having upper and lower ends, said lower end resting on said support member, the diameter of the lower end of said adapter member being greater than the diameter of said burner and less than the diameter of said cylindrical side wall so that an annular gap is defined between said cylindrical side wall and the lower end of said adapter member, and a food supporting grill resting on the upper end of said adapter member, whereby said adapter member is effective to direct heat from said burner upwardly through said food supporting grill to cook food resting thereon and the gap between the cylindrical side wall and the lower end of said adapter member permits air to flow downwardly through said gap when said burner is in operation in countercurrent relation to the upward flow from said burner to cool said cylindrical side wall and to supply additional air to said burner.
Claim 3
Dependent Claim
58 words
The portable cooking device of claim 1, in which a plurality of said elongated support members extend between and connect said burner to said cylindrical side wall, said support members are arranged in generally radially extending, circumferentially spaced relation, and the lower end of said adapter member rests on and is supported by each of said support members.
Claim 4
Dependent Claim
29 words
The portable cooking device of claim 1, in which at least one opening is provided in the bottom of said bowl-shaped body for supplying supplemental air to said burner.
Claim 5
Dependent Claim
27 words
The portable cooking device of claim 3, in which a ring of said openings is provided in said bottom in substantially underlying relation to said annular burner.
Claim 6
Dependent Claim
225 words
A portable cooking device comprising: a bowl-shaped body having a bottom and an upstanding cylindrical side wall; means carried by the body for supporting it in an upright position on a horizontal surface; a burner; means for supplying a combustible mixture of air and gas to the burner; support means connected to the burner and the body for supporting the burner in the body generally adjacent to the lower portion thereof so that a flame from the burner is protected from the effects of wind during cooking; a grill adapter wider than the width of the burner; means removably supporting the grill adapter in position above the burner so that heat from the burner can grill food on the grill adapter; the grill adapter having a pair of substantially horizontally positioned and vertically spaced apart grating elements and means effectively interconnecting the grating elements so as to be movable as a unit; a plurality of rocks for radiating heat located between the pair of grating elements and simultaneously removable with the grill adapter from the cooking device; and the cooking device having pot or pan support means for supporting the bottom of a pot or pan above the burner when the grill adapter is removed from the cooking device and the cooking device is to be used for cooking food as distinguished from grilling food.
Claim 7
Dependent Claim
225 words
A portable cooking device comprising: a bowl-shaped body having a bottom and an upstanding cylindrical side wall; means carried by the body for supporting it in an upright position on a horizontal surface; a burner; means for supplying a combustible mixture of air and gas to the burner; support means connected to the burner and the body for supporting the burner in the body generally adjacent to the lower portion thereof so that a flame from the burner is protected from the effects of wind during cooking; a grill adapter wider than the width of the burner; means removably supporting the grill adapter in position above the burner so that heat from the burner can grill food on the grill adapter; the grill adapter having a pair of substantially horizontally positioned and vertically spaced apart grating elements and means effectively interconnecting the grating elements so as to be movable as a unit; a plurality of rocks for radiating heat located between the pair of grating elements and simultaneously removable with the grill adapter from the cooking device; and the cooking device having pot or pan support means for supporting the bottom of a pot or pan above the burner when the grill adapter is removed from the cooking device and the cooking device is to be used for cooking food as distinguished from grilling food.
