This invention relates to the art of gas burners for stoves and has for its primary objects the provision of a gas burner that will promote economy in the use of gas and that 6 may be made at a relatively low cost of production. My invention relates to a burner to be employed in the use of natural gas, artificial gas, and the so called bottled gas which is now commonly stored in tanks or drums for distribution to suburban homes that are removed from the gas mains of a central gas plant.

The burner heretofore customarily emloyed has served well for gas as distributed rom a central plant, but by the use of a burner embodying my invention, an economy has been efiected which materially reduces the cost of gas required to cook a meal.

Reference is made to the accompanying drawing in which Fig. 1 is a fragmentary top plan view of a burner embodying my inven tion; Fig. 2 a fr entary side elevation of the burner; and Fig. 3, a front elevation.

Like characters of reference indicate like parts in the several views.

The burner consists essentially of a hollow rin 10 having a su ply tube 11 communieating therewith. nstead of forming the ring 10 to have concentric inner and outer walls, I form the inner wall 12 to have a number of reentering convolutions 13, here shown as five in number with intermediate 1 portions 14 of the inner wall projecting arouately toward the center of the ring 10.

These intermediate portions 14 do not extend entirely to the bottom of the tin 10 but are cut off at a slight distance therea ve to have shelves 15 extending from their lower ends-back to and joinin with the inner wall 40 12. The outer wall 16 o the ring 10 is curved around from the floor 17, inwardly and thence sharply upwardly and angularly downwardly to merge into the convolutions and intermediate portions of the inner wall of the ring. On the angular surface 18 above referred to, are arranged orifices of a plurality of holes 19 which extend substantially vertically through the wall to communicate with the interior 'of the burner. Also on the upper portion of the outer wall 16, arranged in the mo. mm Io. 44am.

circle from which the wall 16 curves around and thence passes inwardly and upwardly, are provided a plurality of holes 20 also communicating with the mterior ofthe burn er. It is to be noted that both sets of holes 19 and 20 are located on sharply inclined surfaces of the burner.

The supply tube 11 is fixed to the ring 10 to one si e thereof so that ases flow into the ring tangentially instead 0 radially whereby the incoming gases are directed around the passage within the rin 10. A small part of such gas may there ore flow circumferentially entirely therearound immediately above the floor 17, but the greater part is thrown into considerable turbulence by passing around the restrictions and enlargements caused by the convolutions 13 and intermediate portions 14. It is also to be noted that the tube 11 is widened at its juncture with the ring 10 to permit of the expansion of the in coming due to the heated burner without restricting its flow.

Gas is supplied through the usual nozzle 21 discharging through an air mixing chamber 22 which has the customary slide damper air control 23.

The s is admitted in very small quantities t rough the mixer where it becomes mixed with air and the gas-air mixture flows on into the ring 10, where, by reason of the turbulent flow therearound, the air becomes intimately mixed with the gas to promote better combustion. The arrangement of the holes 19 is such that by being at the highest level a smaller flame, can be employed when simmering is desired. All of the secondary air is supplied through the center of the ring, and when the gas is supplied at the full quantity, this secondary air tends to drive the flame outwardly across the under side of cooking utensils placed over the burner. By placing the holes 19 and 20 on the steep surfaces, material boiling over from utensils thereabove is deflected so as to roll off by gravity rather than remain on the burner and clog the holes.

While I have described and shown my invention in the one best form as now known no to me, it is obvious that structural deviations may be made from that form without departing from the spirit of the invention and I, therefore, do not desire to be limited to that precise form, nor any more than may be required by the following claims.

I claim: I

1. In a gas burner, a ring, a supply pipe entering the ring substantially tangential thereto, and said ring having a lower portion of uniform width and an upper portion with reentering walls causing restrictions in the passa e t erearound.

2. n a gas burner, a ring having inner and outer walls, the upper portion of one of said walls for ap -roximately half of its height being formed to have convolutions to form enlargements in the passage around between the walls, and the lower ortions of both of said walls being united into a uniform annular passageway 3. In a gas burner, a ring having inner and outer walls, the upper portion of one of said walls for ap roximately half of its height being formed to have convolutions to form enlargements in the passage around between the walls, and the lower portions of both of said walls being united into a uniform annular passageway, and an intake pipe discharging tangentially into said ring. 4. In a gas burner, a ring having inner and outer walls, the upper portion of one of said walls for approximately half of its height being formed to have convolutions to form enlargements in the passage around between the walls, and the lower portions of both of said walls being united into a uniform annular passageway, the upper ends of said walls being united at a sharp angle to provide an incline sloping downwardly within the ring and having an annular row of holes therethrough.

5. In a gas burner, a ring having inner and outer walls, the upper portion of one of said walls for a proximately half of its height being formed to have convolutions to form enlargements in the passage around between the walls, and the lower portions of both of said walls being united into a uniform annular passageway, the upper ends of said walls being united at a sharp angle to provide an incline sloping downwardly within the ring and having an annular row of holes therethrough, and an intake pipe dischar 'ng tangentially into said ring.

6. n a gas burner, a ring having inner and outer walls, one of said walls being formed to have convolutions to form enlargements in the passage around between the walls, and the lower ends of said walls being united into a uniform annular passageway, the upper ends of said walls being united at a sharp angle to provide an incline sloping downwardly within the ring and having an annular row of holes therethrough, and an intake pipe discharging tangentially into said ring, the outer of said walls being curved sharply inwardly toward said sharp angle and having an annular row of holes therearound in a plane immediately below the inward curve, the plane of said outer wall holes being below the plane of said holes through the inclined surface.

7. In a gas burner, a hollow ring having a plurality of jet holes therethrough on the upper portion, and means within the ring for producing turbulence of the as flowing therearound and an intake pipe ischarging tangentially into said ring, said intake being widened at its juncture with the ring.

8. In a gas burner, a hollow ring having a plurality of jet holes therethrough on the upper portion, and means within the ring for producing turbulence of the gas flowing therearound, a as well around the under side of the ring and an intake pipe discharging tangentially into said ring, said intake being widened at its juncture with the ring.

9. 'A gas burner comprising an annular body-portion having a lower uniform annular passage therein and an annular passage above said lower one having walls with convolutions to form enlargements in that part of the passageway, the inner and outer walls of the passageway being united and formed to provide inclines slo ing downwardly toward each of said wa lls, said inclines provided with jet orifices, and an in take 1pe discharging tangentially into said annu ar body and widened at its juncture with the body.

10. A gas burner comprising an annular body-portion having a lower uniform annular passage therein and an annular passage above said lower one having walls with convolution to form enlargements in that part of the passageway and shelves at their junctions, the inner and outer walls of the passageway being united and formed to provide inclines sloping downwardly toward each of said walls, said inclines provided with jet openings, and an intake pipe discharging tangentially into said annular body.

In testimony whereof I afiix my signature.

GEORGE G. ALIG.
