This invention relates to stoves of various kinds and has for its object to provide a new and im proved sheet metal construction for a stove plate or grid for a stove. A further object of the invention is to so con struct the stove plate or grid that it cannot buckle due to expansion when heat is applied thereto. Another object of this invention is to incor porate the stove plate or grid in the top of the 10 stove as an integral part thereof and divide the stove plate or grid into sections by means of slots and openings in order to permit a free expansion of these sections and prevent a buckling thereof. All these and other objects and attendant ad 15 vantages of this invention will become more read (Cl. 126-—214) inner ends thereof are free to expand toward the common open center ‘of the top 2. When heat is applied to the grid each sector thereof is thus free to expand in three directions which prevents a buckling of the grid or any part thereof and 5: provides at all times a uniformly even support for the cooking utensil supported thereon. The sectors of the grid are perforated with segmental slits 8, 8' which are provided with the louvers 9, 9 so as to partially cover the heating 10 unit l0 located within the sheet metal housing I while permitting an ef?cient radiation thru the grid of the heat generated by the heating unit. The heating unit l0 may be any one of well known types of heating units, the one illustrated ily apparent from the detailed description thereof in‘ the drawing being made up of refractory ma terial with open grooves II, II provided in the which follows, reference being had to the accom top thereof and the heating coil I2 mounted in panying drawing in which Figure 1 is a top plan view of an electric stove these grooves. This heating unit is clamped to the bottom of the supporting plate or grid by 20 20 incorporating my invention. Figure 2 is a vertical sectional view thereof, means of the clamping screws l3 which pass thru the grid and the refractory‘ body of the heating taken on the line 2’:c—2ac of Figure 1. In the ?gures like reference numerals indicate unit at diametrically opposite points near their outer edges thereof. A central anchoring screw like parts. 14 passes thru the open center 1 of the grid and 25 The stove plate or grid construction for burn 25 ers or stoves, forming the subject matter of my the center of the heating unit and carries the washers I5 and I6 which hold the free inner present invention, is an improvement of the sup porting plate or grid illustrated and described in ends of the grid sectors between them level with each other and uniformly spaced from the cen my prior application Serial No. 7,238 ?led Feb 30 ruary 13, 1935. In the present invention the stove ter of the heating unit. The refractory body of 30 plate or grid is divided into sections which may the heating unit is thus clamped against the expand separately and thus take care of equal under side of the stove plate or grid with the sectors thereof free to expand above the heating and unequal expansions of these sections With out causing a buckling of any part or portion of unit parallel thereto. Each of the clamping screws l3 extends below 35 the stove plate or grid. The novel arrangement of the openings in the sheet metal stove plate or the refractory body of the heating unit I0 and clamps a shield l'l against the under side of the grid serves to equally distribute the heat gen erated by the heating unit and efficiently apply top of the housing around the heating unit and holds a cover I8 in place in the open bottom of the heat against the bottom of any cooking uten the housing I to close the housing. 40 40 sil supported thereon. Additional louvered openings I9, 19 are ar In the form illustrated in the ?gures the stove which has the stove plate or grid incorporated ranged on the outside of the circular supporting therein comprises a sheet metal housing I with and stiffening ribs 4 so as to direct heat from a top 2 in which the stove plate or grid is formed the heating unit against the portion of the bot 45 as an integral part thereof. The outline of the tom cooking utensil which overhangs the stove 45 grid is de?ned by the small circular ridge 3 in plate or directs heat against the outer walls of a the middle of the grid and the large circular ridge cooking utensil supported on the stove plate.
