This invention relates to the general art of gas stovesor ranges and has reference more particularly to an improved burner top for the same.

More particularly, the present; invention relates to a. knowntype ofgas stove or range wherein the burner top plate isprovided with depending flame guards below-fthe burner openings therein which, at their lower ends, encircle the burners and are designed -to conserve heat by preventing-the flames from spreading laterally through the space between the burner top plate and the usual drip pan and directing substantially the entire body of the flame against the bottom of' the cookingvessel, thus increasingthe portion of the totalheat usefully employed in the cooking operation. i

Among the objects of the invention are, to reduce the cost of manufacture of burner, top plates of this type, simplify the construction and reduce the number. of parts heretofore-used, provide easy access to'the burners, drip pan and other underlying parts, and provide a modification of the modern type of gas stove or range that spell both greater economy of fuel and increased cooking efliciency.

' One practical form in which the invention drawings, in which- Fig. l is a top plan view of a burner top, its supporting frame, and a group of-four burners,

the burner top being provided with the improved .flame guards of the present invention.

Fig. 2 is afron't rear section taken on the line 2 -2..of Fig. 1.

plied to a gas stove comprising vertical side and rear walls Ill and II respectively, a top frame I2 formed with an internal ledge supporting a pair of removable burner top plates l4 equipped with grate bars l5, burners l6 carried 'by mixing tubes" l supplied with fuel from a front main fold it, and removable burner grates l9 sup.- ported in seats 20 formed in thelaumer plates l4, theseseats surrounding openings 2| in the burner top plates l4 directly above the burners. r,

m be embodiedis illustrated in the accompanying 1 (on. ce-s91 Continuous with the seats 28 which form the margins of the openings 25, are depending flame guards. In the preferred form of such guard, the samecomprises an upwardly flaring upper portion 22 and a. substantially cylindrical lower por- :tion 23 which, as clearly shown in Figs. 2 and 3,

completely surrounds the upper portion of the 'burner, with a slight clearance sufficientto admit the flow of secondary air to the flame. These flame guards may be integral with the burner top plate, as shown, or, attached thereto, but however they m'ay be connected to the top plate, they are continuous with the latter so as to form a complete barrier against the lateral .gspread of flame through the space underlying the burner top plates. In this way, practically the entire- 5 amount of heat given off by the flame is applied directly to the bottom of the cooking vessel on the grate l9.

To insure an adequate volume of secondary air, the burner tops I! are formed with marginal holes 24 (Fig. 1)- that admit air'freely to the space below the plates, which air is thendrawn upwardly by the heat of the burner flames through ther space between the lower end of the flame and the burner itself.' I

I claim: w In a multiple burner gas stove, the combinationwith a top frame formed with an internal countersunk marginal ledge, and burners located below said, frame, of a plurality of removable burner .top plates seated on said ledge in edgeto-edge contact and equipped with aligned grate bars, each of said burner top plates and its grate bars having openings therethrough directly over .a corresponding number of burners'and of great er diameter than said burners, integral imper-i fo'rate upwardly flaring flameguards continuouswith and depending from the margins of saidopenings respectively and formed with cylindrical lower open end portions encircling said burners ondary air, and removable burner grates seatedin the upper ends of said flame guards.
