Application January 25, 1937', Serial No. 122,121
9 Claims.
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

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

the bottom of the supporting plate or grid by 20

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

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
