Abstract

A multiple gas burner assembly has two burners spaced apart by a bridge burner. An axis extending through the first and third burner intersects the perimeter of the bridging second burner. The second burner provides a means for providing a substantially continuous flame perimeter and continuous heating intermediate the first burner and third burner when the three burners are lit.

2. The multiple burner assembly of claim 1 wherein the first and second burners have a first and a second base, respectively and the first and second bases are integrally formed.

3. The multiple burner assembly of claim 1 wherein the first, second and third burners have a first base, a second base and a third base respectively, and the first, second and third bases are integrally formed.

4. The multiple burner assembly of claim 1 wherein the first and second burners produce first and second flame perimeters, respectively, when lit, and a third perimeter is comprised of the first and second flame perimeters with the third perimeter having a distance substantially equal to the sum of distances of the first and second perimeters.

5. The multiple burner assembly of claim 4 wherein the third burner produces a fourth flame perimeter when lit, and a fifth flame perimeter is comprised of the first, second and fourth perimeters with the fifth perimeter having a distance substantially equal to the sum of distances of the first, second and fourth perimeters.

6. The multiple burner assembly of claim 1 wherein the first burner produces a first flame perimeter and the third burner produces a fourth flame perimeter, and said first and fourth flame perimeters are separate and adapted for the heating of separate cooking utensils.

7. The multiple burner assembly of claim 5 wherein the fifth flame perimeter provides substantially continuous heating over a length of at least about twelve inches.

8. A multiple burner assembly comprising:

a generally ovular base having a major axis and a minor axis;

an ovular perimeter wall upstanding from the base having flame ports therein;

baffles extending across the ovular base and wall structure generally perpendicular to the major axis, and defining first, second and third chambers;

first, second and third openings in the base within first, second and third chambers respectively; and

first, second and third removable caps mounted over at least a portion of the wall flame ports, and over at least a portion of the baffles to enclose the first, second, third chambers, respectively, with the at least one cap extending cantileveredly beyond the outer perimeter wall, and forming a continuous cap when installed, wherein the first and second burners meet at a first baffle, the first and second caps extend over and abut atop a first retaining ridge on the first baffle, the second and third burners meet at a second baffle and the second and third caps extend over and abut atop a second retaining ridge on the second baffle with said first, second and third caps providing a larger perimeter than a perimeter of the flame ports of the first, second and third flame ports.

9. The multiple burner assembly of claim 8 wherein the base, wall and baffles are integrally formed.

10. A cooker with a gas burner assembly comprising:

a first burner having a first gas supply to a first chamber defined in part by a first wall, and a plurality of flame ports located about a portion of a perimeter of the first wall of the first burner;

a second burner proximate to the first burner having a second gas supply to a second chamber defined in part by a second wall, and a plurality of flame ports located about a portion of a perimeter of the second wall of the second burner, and

a first baffle separating the first burner from the second burner and having a first retaining ridge on top thereof;

a third burner proximate to the second burner having a third gas supply to a third chamber defined in part by a third wall, and a plurality of flame ports located about a portion of a perimeter of the third wall of the third burner;

a second baffle separating the second burner from the third burner and having a second retaining ridge on top thereof;

said second burner being intermediate the first and third burners;

wherein when the first, second and third burners are lit, at least a portion of the flame ports of the first, second and third burners cooperate to form a flame perimeter about the first, second and third burners and an axis of relatively continuous heating extending through the first and the third burners with the second burner having first and second segments providing the plurality of flame ports progressing in a direction parallel to axis with the first and second segments spaced on opposite sides of the axis;

and first, second and third removable caps over the first, second and third burners assisting in defining the first, second and third chambers, respectively, with the at least one cap extending cantileveredly beyond the flame ports, and over the first and second baffles wherein the first and second burners meet at a first baffle, the first and second caps extend over and abut atop the first retaining ridge, the second and third burners meet at a second baffle and the second and third caps extend over and abut atop the second retaining ridge, and said first, second and third caps providing a larger perimeter than a perimeter of the flame ports of the first, second and third flame ports.

11. The cooker of claim 10 further comprising a first igniter operable with the first burner;

13. The cooker of claim 11 in combination with a substantially planar backsplash at an upper surface of a range, wherein said first, second and third burners are located at an upper surface of the range and along an axis extending substantially perpendicular to the backsplash.

14. A cooker having a multiple burner assembly comprising:

a first burner having a gas supply and a first control means for igniting and adjusting the flow of gas to the first burner;

a second burner having a gas supply and a second control means for igniting and adjusting the flow of gas to the second burner, said first and second burners being spaced apart for the heating of separate cooking utensils; and

a bridge burner intermediate and separated by baffles from said first and second burners for providing an axis of relatively continuous heating from the first burner to the second burner with the bridge burner having two segments of flame orifices oppositely disposed relative to the axis extending intermediate the first and second burner and first, second and third removable caps a extending cantileveredly over and beyond the flame orifices in a direction perpendicular to the axis, said first, second and third removable caps at least partially covering the flame orifices, and wherein the first and second burners meet at a first baffle, the first and second caps extend over and abut atop a first retaining ridge on the first baffle, the second and third burners meet at a second baffle, and the second and third caps extend over and abut atop a second retaining ridge on the second baffle with said first, second and third caps providing a larger perimeter than a perimeter of the flame ports of the first, second and third flame ports.
