6 Claims. (Cl. 158-417) tour of the outer wall 5. The unobstructed on- My invention relates generally to gas burners and more particularly to gas burners of the double burner cons tube in which the truction, including i a mixing gas is mixed with a certain amount of primary air before issuing from the flame openings or ports.

The principal object of the invention is to provide means for checking the flow of air and gas mixture at a point adjacent to but slightly below the flame openings.

Other objects and advantages will become apparent from the following description taken in connection with the accompanying drawing which illustrates a preferred embodiment of the invention, and in which:

Figure 1 is a plan view of my improved burner;

Figure 2 is a longitudinal sectional view taken on the line 2--2 of Figure 1;

Figure 3 is a plan view of the burner partly in section, the section Figure 2.

being taken on line 3-3 of Referring more particularly to the drawing B denotes the burner as a whole, comprising the gas and air mixing tube I, adapted to be supplied with gas thro opening 2, from ugh the customary gas cook a manifold, not shown. Primary air is drawn into the mixing tube through side air openings 2 by the inflowing gas. A collar 3 is preferably provided for regulating the inflow of air.

The inner end of the tube I terminates in an enlarged bowl-shaped burner head 4, having an upstanding outer ner flange or wall 6 flange or wall 5 and an inconcentrically disposed with respect to and spaced from the outer wall 5.

While the outer wall is fluted to increase The annular space between the may be round.

walls 5 and 6 constitutes a l for the inner and outer 5 of the burner as shown, the flame area, this wall distributing chamber flame outlets or ports 8 and 9 respectively. Secondary air for the port 6 is drawn in through a centrally disposed passage lli extending vertically through the burner head 4, and within The distributing the top horizontal by means of threaded in bosses l3 formed in head portion 4. Pla

The outer peripheral edge of the plate II extends beyond or overhangs the wall 5 and port 9, and thus serves as a guard to prevent food and other flame openings.

Likewise drippings from clogging the the inner periphery of plate H is slightly beveled as at l2, so that this beveled portion will slightly overhang the inner face of wall 6.

An annular baflle A baffle member (3 located preferably plate I5, positioned within the top of distributing chamber 1, slightly below the top edges of wall s 5 and 6, is adjustably supported on the bolts l6 previously referred to.

The inner peripheral seats snugly against 6, and preferably forms passage of gas betw edge of annular plate l5 the outer face of inner wall a tight seal against the een the inner wall and the plate, and the outer edge of plate I5 is spaced from the inner face the annular vertically In order to counteract flowing stream of ga portion of the opening or passage of outerwall 5 to provide disposed gas passage I6. the tendency of the swiftly s to be discharged past that IS" adjacent the mixing tube, I have found it desirable to increase the width of the passage at this point as tirely unobstructed,

as distinguished from the Venturi type generally employed. The elimination of the venturi is made possible by the use of the plate l5, and

full flow or unchecked ture being delivered the latter also permits of a head of combustible mixto the burner head in close proximity to ports 8 and 9, which of course is most desirable.

customarily used can burner can readily b A tube of much larger size than thus be employed and the e turned to a very low simmering position without danger of back firing as the flame is sufficien lar passage [6.

The action of the gas mixture from tube l6 and thence out passage 9, to support a ring tly removed from the annuburner is as follows: The I passes through annular through annular port like outer flame. A portion of the gas will fiow inwardly over the top of plate IE to and through the inner annular port 8 to support a second and smaller inner annular flame, the secondary air for which is drawn through opening l0.

The baflle plate l5 will be adjusted to its proper height by the manufacturer, but if required further adjustment can be made by the user, nuts 20, 20' being provided for this purpose. Top plate I I can also be readily raised and lowered by screwing up or unscrewing a nut l8. A split Washer I9 is preferably interposed between the plate II and the nut 20 so that adjustment of the top plate can be made without interfering with the fixed adjustment of the baffle plate.

Having thus described my invention:

1. A gas burner comprising a bowl shaped body having an open top, an outer wall and a substantially cylindrical inner wall axially aligned with and spaced from said outer wall to provide a substantially ring shaped mixing chamber, an axially perforated plate adjustably mounted slightly above said open top providing substantially concentric inner and outer circumferential outlet passages from said chamber to the open atmosphere, means for mounting said plate, and a ring shaped, solid, horizontally arranged baflle member within said mixing chamber for subdividing same and connecting the subdivisions of said chamber by a narrow substantially ring shaped passage adjacent to the outer Wall of said chamber for directing the gas toward said outer outlet passage, said means for supporting said plate also supporting said baffle member in slightly spaced relation from the open top of said mixing chamber.

2. A gas burner comprising a body including a burner manifold and provided with an open top and a substantially ring shaped mixing chamber, a plate fitting the open top of said chamber mounted slightly above said open top for providing substantially concentric outlet passages from said chamber to the open atmosphere, and a ring shaped baifie member within said mixing chamber shaped to restrict the passage through said chamber to a narrow substantially ring shaped passage adjacent to the outer wall of said chamber, said passage being of greater width at the burner portion adjacent said manifold to insure uniform supply of gas to the concentric passages throughout their entire circumferential area.

3. A gas burner comprising a body having an open top and a substantially ring shaped mixing chamber, the inner cylindrical wall of which forms an open ended passage and the outer wall of which is fluted to provide an outlet opening of varying area at the top of said chamber, a flat, centrally perforated plate shaped to fit the open top of said chamber mounted slightly above the open top of said body to provide substantially concentric outlet passages from said chamber to the open atmosphere, means within said open ended passage to partly obstruct a fiow of air through said open ended passage, and a ring shaped baflie member within said chamber shaped to subdivide said chamber into upper and lower compartments communicating with each other through a restricted narrow ring shaped opening adjacent to the outer wall of said chamber.

4. A gas burner comprising a bowl shaped body having an open top, a fluted outer wall and a cylindrical inner wall axially aligned with and spaced from said outer wall to provide a substantially ring-shaped mixing chamber enclosing an axial passage through said body, a flat, axially perforated plate having the irregular configuration of said chamber mounted slightly above the open top thereof in alignment with the inner and outer walls to provide two substantially concentric narrow outlet passages adjacent to the inner and outer walls of said chamber, and a ring shaped bafile member within said chamber shaped to form a restricted narrow ring shaped passage adjacent to the outer wall of said cham her.

5. A gas burner comprising a manifold of unrestricted cross section, a bowl shaped body at one end of said manifold having an open top and a substantially ring shaped mixing chamber, a flat, axially perforated plate having approximately the configuration of said mixing chamber mounted slightly above the open top of said body to provide substantiallyconcentric narrow inner and outer outlet passages for the gas and air mixture discharged from said mixing chamber, and a ring shaped plate within said chamber and. contacting with the inner Wall thereof and slightly spaced from the outer wall of said chamber and adapted to subdivide said chamber into upper and lower compartments communicating with each other through a restricted ring shaped openmg.

6. A gas burner comprising a body having an open top and a substantially ring shaped distributing chamber the inner wall of which forms an open ended passage, a plate fitting the open top of said chamber mounted slightly above said open top to provide an outlet passage from said chamber to the open atmosphere, a plurality of supporting posts for said plate extended through said chamber and a baiile plate within said chamber adjustably mounted upon said posts and slightly spaced from the open top of said chamber, and a baflle member adjustably mounted in said passage.
