COOKING PLATE STOVE TOP Filed May 21, 1951 Patented Dec. 15," 1931 v Y roansrvgnnrwrnnn, onfcnrcheofrrmmors it ,cooxme PLATE srov'n "T01 1 Application filed May 21, 1531.; Serial Nataaoiaf y This invention relates tostove top cooking plateparticularly adapted, though not necessarily limitedin its use with gas or vapor ranges, and one of the objects of the invention is to provide an improved cooking top which is readily removable and so shaped that the products of combustion from the i burn'er-willpass throughthe plate and circulate'across the topthereof to contact with and flow across'the bottom of" the cooking utensilorreceptacle placed thereupon.

'A further object is to provide in a plate of this character means forcausing the products of combustion and the heated air to flow intortuous passages across the top of the plate, the plateibeing so constructedthat overow from'the pots and kettles will run to wardthe center of the topto be evaporated 1 before theypass through-the plateito' the y, A'further object is to provide in a plateor 7 top of this character meansproviding, for

burner. i

the escape of theheated air and products of combustion beyond the'edge of the kettle or pot afterpassing over the top of the plate. To theattaininent of'these endsjand the accomplishment of other new-and useful ob jects as will appear, the inventionconsists l 1, Figure 2; of a plate top of this characin; the features of noveltyin substantially the construction, combination and arrangement of the several parts; hereinafter more fully described and claimed and shown the accompanying drawings illustrating this inventionfand in which If I T" Figure l 'is a sectional view taken'on line ter constructed in accordancewith the prin- 'ciples of this invention, and showing the sameas applied to-a-portion of a stove. Figure 2 is a'top plan view of the plate. -Figure 3 is a detail sectional on line 3'? ,Figure 2'. j

Figure 4 isa bottom plan-view of 'a portion of one corner of the plate. 1 a In gas stovesof the type to which thisinvention is particularly; applicable; it. is 'customaryito provide removable grids in the top of the stove; and which grids are formed spaced bars and are .providedwith-unobstructed spaces located above the burners, so

view taken,

as notto interfere with the products of combustion passing therethrough, the-pots or COOklDglltGllSllS being placed'upon the grids. The size ofthe stove and the numberof burners determines the number of: grids to be '85 I employed. a A a A *WVith theuseof thesegrids', consider-able of the heat and products of combustion'from the burner are lost-as theywill'pass. freely p through the gridsand all of the products of 00 1 combustion will notflbe directed against; the

bottom of the utensils l In-the, present invention these grids, are dispensed with and: in lieu -thereof there is provided one or more 7 plates designated gem. erally by the reference numeral 10, according to the-sizeof the-stove. Each of-these "platesis constructed of 'any suitable mate- "rial and-the bodyportionthereofis provided I i with an upperfiat surface 11; In thepr'esen't form of the invention one of the platesis shown which is rectangular in configuration and the plate is provided with openingsfl2 therethrough of a substantial size. .The portions of the platein proximity to these open ings l2 incline downwardly as at l3 from' the :flat upper surface' ll tow rd ea hw f zth openings 12.

- Supported by the inclined portions of 1 the plate area plurality ofconcentrically ar- ;mng d ribs or projections 14 thatextend for ashort distance'above the top of the inclined portionof the plate and these ribs are spaced 'laterally and longitudinally from each other so as to-form tortuous'p'assages'15'leading'fl across? the top of the inclined portion ofthe -plate,"and "communicating with these passages are additional-passages 16 formedfgin "the upper flatflsurface of the plate to open; 1 through the top thereof, so-that whena pot? .orrec eptacle 17 ispilaced in position over the respective burners 18, which latter are arranged beneath theopenings 12, the prod-o ucts'of combustion from the burner and the heated air will flow through the openings 12* a and through the tortuous passages 15 across the topsurface' of the plate and against andia acrossthe bottom the utensil. The products of combustion and-heated' air wil1 'find j their escape through the'openings I 16 in the? 99 p upper surface of the plate, and beyond the periphery of the receptacle.

A plate of this character is removably supported upon a ledge or flange 19 encompassing the usual opening in the top of the stove designated generally by the reference numeral 20, and projecting below the lower face of the plate 1Q at suitable points, and as is usual in castings, are lugs or projections 21, which latter may be filed or shaped so as to overcome the imperfections in casting and to permit the plate to rest fiat upon the flange or flanges 19. These lugs or projections 21 may be arranged at any point about the circumference of the plate and on the lower face thereof and may be of any desired width and length.

The plate is provided with attentional openings 22 therethrough for the escape of heated airfrom beneath the plate and may also be provided with an opening therethrough disposed above the usual pilot light 'on the stove. I v p It Will be manifest that with a plate of this character considerable heat will be radiated beneath the bottom thereof and in order to provide means whereby this radiated heat may be employed in the heating of the utensil, there may be provided in the bottom of the grooves or spaces formed between the respectiveseries of projections 14;, openings 2 deny .deslred size and of any desired number, These openings may be located in proxim-ity to the openings formed between the proximate ends of adjacent projections or may be otherwise disposed with relation thereto, and a circulation of the heated air through'such openings from beneath the plate .will be induced by the circulation of the air on'the top of the plate through the tortuous passages 15.

If desired anupright flange 25 may encompass the openings 12 to assist in directing the products of combustionthrough the .openings 12.

By reason of the tortuous passages and of the openings 24, a circulation of the heated air and products of combustion across the top of the plate will be insured and the heated air will escape through the openings 16 in the top surface of the plate and will be thereby. prevented from being directed back against thefiame of the burner 18.

While the preferred form of the invention hasbeen herein shown and described,it

is to be understood that various changes may be made in the details of construction and in the comblnation and arrangement of the several parts, within the. scope of the claims, "2150 without departing from the spirit of this invention. a
