GAS BURNER HEAD Filed Jan. 16, 1956 GAS BURNER HEAD Almer H. Brodbeck, St. Louis, and Harold C. Reinhart, Ferguson, Mo., assignors to Food Giant Markets, Inc., a corporation of New Jersey Application January 16, 1956, Serial No. 559,455 1- Glaim. (GI: 158--116) This inventionrelates to gas burner heads used on cookingranges.

Among the several objects of the invention may be noted the provision. of. an improved burner head adapted to. burn, evenly at all buring rates without flash. back through the, burner ports and without blowout; the pro vision of a burner head of the class described in which an optimum of secondary aeration is obtained at all burning rates; and the provision of a burner head of this class provided with means to inhibit clogging due to spill-over from cooking vessel contents, but which if clogged may readily be disassembled for convenient cleaning. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, features of construction, and

and the scope of which will be indicated in the following claim.

In the accompanying drawings, in which one of various possible embodiments of the invention is illustrated,

Fig. 1 is a vertical section through a burner assembly made according to the invention;

Fig. 2 is a right-hand elevation of the assembly shown in Fig. 1;

Fig. 3 is a plan view of the assembly, parts being broken away for purposes of description; and,

Fig. 4 is an enlarged fragmentary detail of the upper left-hand portion of Fig. 1.

Corresponding reference characters indicate correspondis shown at numeral 1 an annular hollow body, one side of which is bulged as shown at 3 so as to provide for attachment of a fuel supply pipe 5. Gas and an appropriate amount of primary air are supplied to the body by the pipe 5. A base 7 of the 2,843,199 Patented July 15, 1958 accurately formed cylindric annular port 29 between the ring and the sleeve.

Thering 19 is rovided with a lower tier of ports, for

example, twelve No. 51 drill holes 31 equally spaced. Th

woven to approximately 18 mesh.

On the side of the body 1 opposite the When fuel and primary air are introduced into the port 37, a vertical fishtail flame is produced from the slot 39, the same being ignited by the flame of pilot 43.

Assuming that fuel, including primary air, is introduced into the body 1 through pipe 5, this will pass into the ring 19 and escape through both the upper slots 33 and lower circular ports 31. Ignition takes place from the flame issuing from slot 39, The screen 35 prevents flash back.

plete ring therein. have the elfect of teristic for the gas escaping through the slots 33, even at low burning rates through the latter. It will be noted in this connection that a thin cylinder of fuel including pri- 29 just within the geous results attained.

As various changes could be made in the above constructions without departing from the scope of the in- 3 vention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

We claim:

A gas burner head comprising an annular gas-transmitting body having an upper opening and a lower threaded opening, a tube threaded into said lower opening extending with substantial clearance through the upper open ing, an outwardly directed flange on the tube above the upper opening, an inward annular seat located around said upper opening, an inwardly uninterrupted cylindric marginal sleeve extending up from said seat part way to said flange, an externally uninterrupted cylindric ring extending between the seat and the flange and spaced a substantial distance outward from the tube and a relatively small distance inward from the sleeve, said ring extending vertically across the space between the upper end of the sleeve and said flange and having a lower tier of openings within the sleeve, which openings are of relatively small individual and total areas, and an upper tier of ports exposed in said space, which ports are of relatively large individual and total areas and being vertically elongate, a circular screen telescoped within said ring and covering said elongate ports, the space between the sleeve and the ring being characterized by the absence of any transverse obstruction thereacross, whereby there is provided a small continuous ring of flame at the upper end of said sleeve and beneath said elongate ports and positioned within upward flow of secondary air from the outside of the sleeve for unimpeded aeration of gas flowing from the elongate ports, said tube, ring and screen being freely removable from the body by unthreading the tube.
