To all whom 'it may concern: E
Be--it known4 that I, CARLOS A. MCNEIR, a citizen" of the United States, residing at Minneapolis, in the county of Hennipin and State of Minnesota, have invented certain new and useful Improvements in 'Water- Grates for Gas-Stoves, of which the following is a specification. v
My invention relates to water grates for gas stoves and has for its object to provide a grate to take the place of the grate ordinar ily furnished with gas stoves wherein there shall be cast integral means directly associated with the grate bars for heating water from the heat ordinarily wasted in regular cooking operations.
. The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.
In the drawings, illustrating the application of my invention in one form, Figure 1 is a plan view of my water heating grate. Fig. 2 is a longitudinal elevational section of my grate taken on line 2 2 of Fig. l and a portion of a gas stove showing the relation of my grate to the gasV stove and burners when my grate is applied to the same. Fig. 3 isa transverse elevational section of my grate taken on line 3-3 of Fig. 1, a burner and a portion of cooking utensil.
A gas stove of ordinary construction having a separate grate for each pair of burners is illustrated in Fig. 2. The body 10 of the same is equipped with a top 11 which receives my grate 12 and also supports a gas burner 13 and the necessary valves 14 and pipes 15 common to all forms of gas stoves. Burner 13 is shown as circular but any form of burner will operate equally well.
My grate proper, shown isolated in Figs. 1 and 3, has a rectangular frame member 16 adapted to cover two burners and rests upon the top 11 and has grate bars 17 and grate bars 18 open at 28 similar to the ordinary form of grate. A pair of hollow annular circuitous members 19 and 20 are united at 21 and are cast integral with grate bars 17 and 18 and below the tops of the same, as clearly shown in Figs. 1 and 3. Member 19 is provided with a downwardly-projecting pipe connection 22 into which is screwed an inlet pipe 23, and member 20 is'provided with an outwardlyf projecting pipe connection 24 into which is screwed an outlet pipe 25. The water passes a plurality of through Yfrom a reservoir, not shown in the draw- :I
As seen in` Figs. 2 and 3, the burners 13 i I come somewhat below members' 19 and 20,
leaving spaces 26 between said burners and said members, the flames issuing upward from said burners through central apertures 28 in the members 19 and 20 to reach the utensils 29 placed on top of grate bars 17 and 18. It will be noted that the lower surfaces 27 of members 19 and 20 are slightly curved and slope upward. This characteristic is of double value. VSurfaces 27 submit partial areas to the outermost portion of the ames which with the ordinary form of grate never come in sils to be heated and are hence wasted. Sec* ondly, the ames rising through apertures 28 cause a draft through spaces 26, which draft tends to deflect the ames from the bottom of the receptacles 29 downward to completely surround members 19 and 20 and so effectively utilize the wasted heat in heating the water within said members. Any heat taken up by the grate bars 17 and 18 is quickly transferred to the water within members 19 and 20, thus keeping all portions of my grate at a temperature not greater than the boiling temperature of water, and so serious injury to the operator or any substance left upon the grate cannot take place. Such grates may readily be substituted for the grates at present used with various forms and styles of gas stoves, and they will utilize to a greater degree the full heating capacity of the combustible consumed.
I claim:
1. A grate for gas stoves comprising an integral casting consisting of a rectangular frame portion adapted to be removably positioned on the top of a gas stove, said casting including a central portion embodying a hollow member extending longitudinally across the grate and including one or more expanded portions having a central opening adapted to be positioned Vabove the gas burner when the grate is set upon the stove, and a multiplicity of transverse parallel grate bars connected with said frame and cast integral with said central member and with the expanded portions thereof.
