COOK STOVE Filed Oct. 22, 1926 Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE CHARLES M, FITCH, OF KANKAKEE, ILLINOIS, ASSIGNOR 'IO SEARS, ROEBUCK AND CO., OF CHICAGO, ILLINOIS, A CORPORATION OF ,NEW YORK eooxsrovn Application filed October 22, 1926. Serial No. 143,334.

This invention relates generally to cook stoves, and is more particularly pertinentto cooking tops for oil or other stoves with burner having one or more .sections const-ructed to provide a burner hole and an auxiliary warming hole heated therefrom.

In prior devices of this type, it has sometimes been common practice to form the sec tional top in such manner that the duct which connects the two heating openings is permanently closed. This construction is objec tionable due to the difficulty encountered in efl'ectively cleaning the section. The duct becomes a trap which collects liquids, dirt and other refuse. An important object of this invention, therefore, is to provide a stove top of this description which may be completely disassembled to permit ready access into the interior of the section for cleaning.

A further object of this invention is to create a novel stove top of this type which may be formed in whole or in part of sheet.

metal construction, capable of economical manufacture and yet of a very rugged character.

Other objects and advantages will become apparent from the following description and in the accompanying drawings, in which:

Figure 1 is a plan view of a stove top comprising a plurality of sections.

Fig. 2 is an enlarged plan view of a single section in its preferred form.

Fig. 3 is a longitudinal section taken on the line 33 of Figure 1.

Fig. 4- is a plan view of the central supporting member.

Fig. 5 is an end elevation of the same.

Fig. 6 is a section through one of the supporting lugs.

While I have shown in the drawings and shall describe in detail herein the preferred embodiment of the invention, I do not thereby intend to limit my invention to such construetion, but intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.

This invention is particularly adapted for use in oil stoves in which the burners are customarily located near the front side of the top it is possible to divert a sufficient amount in position by those lugs 16 nearest said neck.

stove. This method of construction leaves a rear space on the surface of the stove top which is not adapted to be used for heating. By the use of the hereinafter described stove of heat from the front burners to an auxiliary heating hole at the rear of the stove whereby the usually wasted space at the rear of the stove will be utilized.

As shown in Fig. 1, the stove top comprises three independent sections generally designated 11, fitting within a rectangular frame. Each of said sections is formed from a flat sheet of metal deep drawn to provide an elongated relatively shallow pan 14; extending from front to rear of the top. The pan thus formed is shaped to provide rounded end portions with a somewhat restricted. in-

'termediate portion 13 (Fig. 2) and bridging this restricted intermediate portion is a plate 17 having forward and rear edges shaped to coact with the rounded end portions of the pan to form circular burner openings In the bottom wall of the pan near the forward end thereof and beneath the forward burner opening is an opening 15 through which the heat rising from a burner positioned beneath the top may pass. As shown in Fig. 3, the bottom of the pan is preferably formed to slope upwardly toward the ends. By this construction, it becomes possible to deepdraw a single piece of sheetmetal into the desired form without producing an undesirable wrinkling of the top surface at the narrower end portions. At appropriate intervals near the top plate 12 the side walls of the pan 14; are struck inwardly to provide a plurality of integral lugs 16 adapted to support certain members to be hereinafter described. Such formation of the lugs avoids perforating the sides of the heat conducting casing or duct.

The plate 17 may be of any suitable material, preferably a casting, and is supported The disposition of the lugs and the arrangement of parts is such that'the surface of the plate 17 is flush or level with the top of the casing. In this manner a pair of heating openings 18 are provided in the top 12, said and 21 of any suitable construction.

openings being connected one with the other by means of the duct formed by the pan section 14 of the casing and the plate 17. Obviously the shape of these openings 18 will de pend upon the conformation of the original opening and the shape of the sides of the plate 17, which, in the present instance, have been designed to provide a pair of circular heating openings.

A flange 19 extending inwardly of the heating openings from each side of the plate 17 serves, with the lugs 16 on the side walls of the pan 14, to support a pair of grids 20 As shown in Fig. 3, the grid 21 which is to be placed over the opening 15 in the pan 14- is supported with the surface thereof level with the top 12, while the other grid 20 has its utensil supporting surface raised a short distance above the top level.

It has been found that, where a sheet metal top is used and is necessarily subjected to a high degree of heat, warping of the top is apt to result. It is advisable, therefore, to provide reinforcing means for said top. Such means may be of any suitable type but herein it is shown as comprising a downwardly extending peripheral rim 22 integrally formed with the top 12.

To receive one or more of the top sections beted frame 23 (Fig. 3) is provided having a groove 24 into which the rim 22 is adapted to fit and hold the top against lateral displacement. The opening 15 in the pan is positioned over one of the burners (shown diagrammatically at 25) in the oil stove with the proper grid 21 supported thereabove.

As a utensil resting upon the grid 21 will substantially close the front heating opening 18, heat from the burner will be deflected rearwardly through the constricted neck to escape through the opening at the rear. A utensil supported upon the rear grid 20 for warming will be held away from the surface of the top by the raised portions and consequently will not interfere with the draft- -necessary for operation of the oil burner.

It will be seen that a stove top has been provided which incorporates an auxiliary warming hole not subject to direct flame from a burner and which embodies the especially advantageous feature of being readily removed, disassembled and cleaned. The simplicity of the two part construction, the cheapness of construction attained by the use of sheet metal, as well as the ease with which the interior of the pan may be exposed for heretofore attained in devices of this character.

I claim as my invention:

1. A cook stove having in combination, a sheet metal member having a flat top surface with an elongatedcentral opening therein,

cleaning are advantages not an integrally formed wall portion depending from said top surface and having an opening therein to receive heat from a burner, a dividing plate adapted to fit in said opening in said top midway of the ends of said opening whereby a pair of openings are provided in and substantially centrally thereof, said bridging member having its opposite ends fitting into the pan and supported thereby so that its upper surface is substantially flush with the upper surface of said plate at the edges of the pan, and utensil supporting grids supported at opposite ends of the pan, said bridging member coacting with the plate to form openings to receive said grids.

3. 111 a cook stove, the combination of a top plate having an elongated. opening therein with a restricted intermediate portion, an

elongated pan having a bottom wall and an constructed in the preferred manner, a rabupright peripheral side wall, the bottom wall having an opening at one end to'receive heat from a burner and the peripheral side wall being shaped to conform to the shape of said opening and depending from the peripheral edge thereof, and utensil supporting means removably supported in said opening at the upper edge of said-pan, said means including grids at opposite ends of the opening and an intermediate bridging portion between the.

grids for said restricted central portion of the opening, said top plate and pan coaeting to provide shouldered seats for said grids and bridging portion with the upper surface of the latter substantially flush with the upper surface of the top plate.

In testimony whereof, I have hereunto affixed my signature. i
