against the side of the oven andagainst the g back splash member of the stove, and leaving only a small crevice between'the supporting frame and the oven and, back splash member, and also a small crevice all around the grate members and between the grate and the supporting frame. Obviously, in the operation of the stove, these oreviceswere soon filled with grease, dirt, etc., and in ad- H dition, such grate frame partially hid the portion of the oven and back splash member below the grate from view.
' The object of the present provide a novel grate structure which is formed directly by stamping the same from sheet steel, the fabricating of the grates being accomplished in a novel manner whereby to present an eflicient supporting surface and at the same time efficiently prevent the transmission of heat from the burner center outwardly to the other portions of the grate. Furthermore, by stamping the grate from sheet metal, I obtain not only a much a better appearing grate structure, but one that can be made much cheaper and more efficiently than cast grates.
A further feature of the present invention resides in the manner of fabricating or shaping the outer edges of the grate structure,
in combination with the manner of supportr t elevation of one of the grate legs or grate bars.
ing the grates by the various parts of; the stove; In this connection, I prefer to form the grates with small projections at the corners and center ends thereof andto ,sup-
port said grates by suitable lugs formed in the walls of the stove members. 1' rhe'result of this structure is in .direct-contrast'to invention is to -l0.10 of Figure 9.
thei'present; standard method of supporting grates as a relatively large space is provided between the walls of the stove and the grates whereby it is possible to quickly clean all parts of the stove adjacent to the grate and thus provide a completely sanitary stove structure. TVVith the walls. of the oven and the walls of the back splash member en- 'ameled, it will be-obvious with this grate structure that such enameled parts below the surface of the grate may be easily seen from the topand'present a very. sanitary appearance.

Figure 9is. a sectional view taken online 9-.9 ofFigure 1 and illustrating the general Figure 10 is a sectional view taken on line The novel grate members of the present invention are formed in two halves as in the ;usual standard construction. Each half, however, is formed by single stamping from one of the grate .structed in accordance with the present in; vention and also showing the manner of supporting the same in position.

sheet metal so as to form a complete stove grate in one stamping operation. It will be obvious, of course, that the grate may be subjected to a finishing or final forming operation, but is preferably formed in one single stamping operation.
In fabricating the grate structure from sheet metal, the frame of the grate is preferably cut out and fabricated as at 1, 2, 3 and 4, the side walls of such frame members being turned down as best shown in Figures 3 and 8. In fabricating these outer frame members, the outer edges of the frames, 2 and 4, are turned down as at 5 and 6,so as to re inforce the grate member lengthwise. The
end frame members 1 and 3 also have their outer edges turned down a relatively great extent as best shown at 7 in Figure 8, but such edges are not turned down to the same extent as the edges of the frame members 2 and 4,
ing operation between the center end lugs 11 and the outer end lugs 12.
The grate bars or leg members 13 are preferably fabricated so as to extend radially inwardly in the usual manner. In forming 'these grate bars, they'are cut out and then turned down soas to form the narrow portions 14 and the wider portions 15, the narabove the burners. As best shown in Figure 9 each narrow portion of each grate bar starts at a point 16 and gradually increases in depth to a point 17, at which point the grate bar widens materially and presents a much.
By this construction it will be obvious that the inner ends of each grate bar are materially strengthened and in addition the heat absorbed by the ends of the grate bars, being positioned over the flame, is quickly dissipated by the gradually enlarging surface area of each grate bar.
It will thus be obvious that the grates are very rigid and capable of supporting a relatively large weight and at the same time the grate bars are so constructedas to quickly dissipate the heat at the points of the grate bars and thus maintain the remaining portion of the grates in a relat vely cool c0nd1t1on and materially ass1st in preserving the smooth enameled finish of the grates.
, The oven wall or side splasher may be designated 20 and preferebly extends downwardly past the level of the grate and preferably terminates in an inwardly extending curve as at 21. This curved portion 21 may 'terminate in a'position'above the drip pan,
butthe essential point to be considered here isthat the side panel 20 extends down past the grate in a straight I plane.
The back wall or back splash member may be generally designated 22 and like the side panel 20 also extends straight down past the level of the grate so as to present a clean smooth surface at the level of the grate. This back splash member 22 is provided with pressed out lugs 23, 24 and 25, which are adapted to register with and support the proj ecting members 11 and 12 of the grates. The front part of the stove may be designated 26 and this front part preferably extends down- 'wardly at the point 27 at right angles to the top surface thereof, whereby such a front member 26 may be suitably connected to the oven wall 20 and the side panel 28. This downward extending portion 27 ofthe front 26 is also provided with suitable pressed out portions29 and 30, whereby to support the projecting members 11 and 12 at the front end of the grate.
It will thus be obvious that the grate members are directly supported by the lugs on the back splash member and on the front member, with the result that they may be very easily removed to permit cleaning of the splash members and the walls of the warming chamber. Furthermore, by reason of the spaces 8, 9 and 1.0,formedat the ends and side of the' grate,it will'permit the ready cleaning of the walls 20, 22 and 28, while the grates are in place. "These relatively large open spaces extending entirely around all sidesof the grate insure complete sanitation of this portion of the stove and will also prevent accumulation of all dirt and grease.
v While I have madeparticular reference to the use of a StIlDPQClsheGt metal grate as one of the features of the present invention, it will be understood that the main feature of the invention resides in the formation of the 1. Burner box structure for cooking stoves comprising agrate formed from stamped out sheet metal, two ends and one side of each grate member being recessed whereby to form projecting members at each corner of the grate, the walls of the burner boxbeing spaced from said recessed portionsto thus present an' open space at the ends and one s1de of each grate when placed in position.
2. In a cooking stove a back splash member extending with a smooth surface straight down past the normal grate level, a front member, a. grate member having projecting portions formed at the ends thereof, and
lugs'po-sitioned on 'sa-id back splash member and on said front member for registering withthe projecting portions of the grate member and supporting same.
3. In a cooking stove, panels formed of sheet metal and extending downwardly in a straight smooth plane past the normal grate level, a pair of grates formed with extending lugs at the corners thereof, whereby to present openings or recessed portions between the lug members, and pressed out'lugs formed in one or more of said panel portions for co-operating with said lugs on the grate members for supporting said grates.
4. In a cooking stove, a plurality of panels forming splash members and .a warming chamber, a front member, one or more grates having spaced narrow projecting members co-operating with narrow lugs on the stove whereby to form open spaces extending completely around the grate or grates and leave said panels with a straight flat surface except for said lugs.
5. A grate structure for cooking stoves comprising extensions formed on the grate member and cooperating with lugs. forming a part of the stove whereby to be supported only by the lugs and forming an open vertical space between said extensions and lugs.
63. A grate structure for cooking stoves of the type adapted to be supported by the oven wall and back splash member, the sides of the grate adjacent the oven wall and back splash member being recessed whereby to form projecting members at cornersof the grate and thus present a vertical open space at the sides of the grate adjacent the oven wall and back splash member.
7. A cooking stove having panels extending downwardly in a smooth plane past the normal grate level, a pair of grates formed with extending lugs at certain corners thereof whereby to present openings or recessed portions between the lug members, and supporting lugs on said panels for cooperating with said lugs on the grate members for supporting said grates and leave vertical open spaces between.
8. In a cooking stove, a plurality of panels forming splash members and a warming chamber, and one or more grates having projecting members cooperating with correspondingly spaced lugs on the stove whereby to form open spaces extending around the sides and back of the grate or grates.
9. Burner box structure for cooking stoves, comprising a grate having inwardlyformed sides and projecting corners, panels extending downwardly in a smooth surfacefrom a point adjacent the top of the grates to form the walls of the burner box, and means carried by said panels cooperating with the corner projections of the grate for supporting the same whereby to present vertically extending spaces between the corner projections and the grate. c
