Abstract
Abstract A gas burner formed from an elongated hollow extrusion having three manifolds formed therein. One of the manifolds comprises a high-pressure manifold delivering raw gas through a series of apertures to the main flame while the second manifold delivers a combustible gas and air mixture through a second series of apertures to the pilot or low-heat flame. The third manifold delivers high-pressure gas through a series of transfer apertures to the second manifold periodically along the entire length of the second manifold. A series of air admission apertures along the second manifold allow air to pass into the gas in the second manifold under the influence of aspiration.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
A gas burner comprising in combination: an elongated hollow extrusion having a front side facing the combustion area with two sets of longitudinally spaced outlet apertures therein; partitions in said extrusion dividing the interior of the extrusion into first, second, and third longitudinally extending manifolds, said first manifold in communication with one of said sets of outlet apertures and said second manifold in communication with the other set of outlet apertures; means closing the ends of said manifolds; means for supplying pressurized gas to said first manifold and said third manifold; and a series of spaced transfer apertures between said third and second manifolds sized and spaced to admit gas to said second manifold at a controlled rate.
Claim 2
Dependent Claim
118 words
A gas burner comprising in combination: an elongated hollow extrusion having a front side facing the combustion area with two sets of longitudinally spaced outlet apertures therein; partitions in said extrusion dividing the interior of the extrusion into first, second, and third longitudinally extending manifolds, said first manifold in communication with one of said sets of outlet apertures and said second manifold in communication with the other set of outlet apertures; means closing the ends of said manifolds; means for supplying pressurized gas to said first manifold and said third manifold; and a series of spaced transfer apertures between said third and second manifolds sized and spaced to admit gas to said second manifold at a controlled rate.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 including a series of air admission apertures in said second manifold sized to pass air at a rate dependent on the flow of gas through said transfer apertures.
Claim 4
Dependent Claim
45 words
The apparatus of claim 2 in which said air admission apertures comprise a series of holes positioned one each next to the transfer apertures so that the flow of gas through said transfer apertures aspirates air into said second manifold through said air admission apertures.
Claim 5
Dependent Claim
26 words
The apparatus of claim 3 in which said extrusion has a generally rectangular cross section with said first and second manifolds positioned along said front side.
Claim 6
Dependent Claim
41 words
The apparatus of claim 4 in which said gas-supplying means comprise a pair of inlet pipes connected to said first and third manifolds whereby gas pressure in one of the manifolds may differ from the gas pressure in the other manifold.
