therefore, has as one of its objects to "provide a gasfcook stove which; will occupy practically no floor space, and Will be neat attractive in appearance as well as substantial; i Y a Another object-of the invention is to pro vide a gas cook stoveof a designadapting it especially for use: small apartments,

the stove beingeonstructed as to be supported directly'upon the wall of the kitchen or kitchenette, thereby occupying much less space than the ordinary stove which is usually supported away from the wall. In this connection; the invention further hasas its object to provide means for protecting the wall, which means constitutes an integral part of tlrestructure', so that Whiletlieburners are located relatively Close to the wall, there will be Ifo likelihood ofthe iwa'll' haying its finish impaired by the accumulation of grease and other foreign matter. Another object of the invention is to provide a: as ceok stove of suclf construetien that the burners and their associated: parts constitute practically a unit independent of the utensil supporting plate ef thestove and its associated parts, so that it is unnecessary to employ various mechanical devices which are now utilized in supporting the burners and their associated parts beneath the grids of theutensil supporting plate. i In the accompanying drawings; v

Figure 1 is a perspective iew of a gas cook stove constructed in accordance with the present invention; installed.

FigureQ is avertical frontto rear sectional view taken substantially on the line B -f Figure 1 looking in the direction indicated by-the arrows, and in detail.

Figure 3 is" a detail vertical transverse sectional view taken substantially on the line of Figure 2, looking in the direction indicated by thea-rrows.

Flgure 413a plan view of one of the burners of'the stove, the utensil supporting plate being shown in broken lines to better illustrate the construction of the burner and its arrangement with relation to the grid opening in said plate.

In the drawings, the numeral 1 indicates ingeneralthe body of the stove which initself is preferably stamped or otherwise inexpensivelyformed. from sheet metal of a suitable gauge and which comprisesa utensil supporting plate indicatedby the numeral. f2, and a backplate 3 which is integralwith the rear edgeof the plate 2 and is formed to extend upwardly'above the plane of the plate 2 at right angles. The plate 2 has its end and front marginal portions overturned to provide downwardly project-- i-ng flanges at which serve not only to add to the attractive appearance of the stove but also to reinforce the said plate and prevent any distortion of the plate.- By reference to Figures 1 and 2 of the drawings, it will be observed that the bend 5 defining the juncture efth'e back plate 3" with the utensil supporting plate 2 is more or less gradual so that grease and other foreign matter cannot lodge in this bend in'a manner to preclude its being-readily removed. It will likewise be observed thatboth the plate 2 and the late 3 are of oblong rectangular form and that the plate 3 is secured to the Wall of the kitchen or kitchenette, which wall is inclicated' by the reference letter IV, by means of screws or other fastening elements 6 which are fitted through openings 7 formed in the back plate 3 'near the upper edge thereof and driven intothe said wa ll. In order to prevent the conduction of heat ffoni the back plate 3 to the Wall, it preferable that asheet of asbestos, indicated by the numeral 8, he arranged between tlie rear "face of the plate 3 and the face of the wall WV, this sheet having its end and upper margins in registration'with the end and upper margins of the said plate 3. The lower portion of thesheet, however, preferably dey pends a greater or less distance below'the plane of the utensil supporting plate 2, this depending portion being indicated by the numeral 9 and being held flat against the wall surface by brackets wl'iichare indicated ingeneral by the numeral 10.. Each of these brackets comprises a vertical attaching portion 11 which is disposed against the face of the depending portion 9 of the asbestos sheet and which is secured by screws 7 or other fastening elements 12 engaged through it and driven into" the wall through the said depending portion of the sheets Each bracket further includes a horizontally and forwardly extending supporting member 13 which extends beneath the utensil supporting plate 2 and is secured thereto by stove bolts or the like indicated by the-numeral 1 1. Each bracket further includes a bracing member 15 which extends from the lower portion of the attaching member 11 upwardly and forwardly to a point ad a cent the forward end of the supportingporiion 13 of the bracket. In this manner. the utensil supporting plate 2 is given firm and substantial support and is further reinforced against distortion.

The utensil-supporting plate 2 of the stove is formed with any desired number'of burner openings, indicated by the numeral 16, and these openings may be arranged in any desired manner, it being assumed,-for convenience in describing the invention, that the plate 2 will be provided with three of said openings arranged in alinement longitudinally of the plate. In forming the said opening 16, thematerial is stamped out from the plate 2 and a depending flange 17 is formed surrounding each opening so as to reinforce the plate at the point of location of each opening.

The gas supply and burner unit is indicated in general by the numeral 18 and comprises a pipe 19 which constitutes a distributer and which for all intents and purposes may be considered as a 'singlepipe. Interposed .in this pipe is a T 20 tothe branch of which is connected a pipe 21, in turn connected by an elbow 22 with the gas supply pipe 23 which extends either upwardly through the floor of the kitchen near the wall thereof or into the kitchen through said wall and adjacent the floor. The pipe 18 extends horizontally below the forward side of-the utensil supporting plate 2 anddistributes gas to the several burner units, a unit being preferably located at each end of the said pipe and one or more units being located in the length of the pipe, depending upon the number of burners. As the burner units are of identical construction, a description of one will suffice for all.

Each of the burner units referredto above comprises a suitable connection 24 by which it is placed in communication with the pipe 19 and with a valve casing which is indicated by the numeral 25, a cut-off-valve plug 26 being mounted in the casing and provided with a handle 27 whereby the fiow of gas past the valve may be controlled. The upper ea l of t e. e a ing 2.5 esteriq lythreadedas at 28, and one branch of a four-branch coupling, indicated by the numeral 29, is fitted onto the said upper end of the valve casing. The two lateral branches of this coupling, indicated by the numeral 30, are left open for the ingress of air to support combustion, and a pipe 31 is fitted into the upper branch of the said coupling and extends upwardly therefrom; The pipe 31 is connected by an elbow 32 with the burner proper in a manner which will now be explained. The said burner comprises a pair of burner tubes indicated by the numeral 33, these tubes being of equal length and being exteriorly threaded at their ends as indicated by the numeral 31, and formed throughout their circun'ifcrcnce with a plurality of rows of perforations 35 through which the gas may issue, and he ignited. One .end of one of the tubes is threaded into the other end of the elbow 32 above referred to and the corresponding end of the other burner tube has fitted to it a closure cap indicated by the numeral 36. The other or rear ends of the burner tubes are threaded into the ends of a pipe return 37 and thus communication is established between the tubes so that gas admixed with air within the coupling 29 will enter the burner tubes and issue through the openings 35 therein. The numeral 38 indicates a nozzle which is threaded into the upper end of the casing 25 of each of the burner valves and is provided with a small discharge orifice 39 arranged to deliver the gas in a fine jet in the direction of the lower ends of the respective pipes 31, thus inducing a flow of air into the coupling 29 which, in effect, constitutes a mixing chamber where it mingles with the gas and the mixture delivered to the burners.

By reference to Figures 1 and 2 of the drawings, it will he observed that each burner is located immediately below and each of these clips having a hook-shaped engaging portion 41 designed to fit about the under side of the respective elbow 37 and partly embrace the same. Of course, the gas supply and burner unit as a whole is supported in a substantial manner byrcason of its connection with the upstanding gas supply pipe 23, but the provision of the clips affords additional support for the unit and likewise prevents any relative displacement of the burners with respect to their openings 16.

Each burner opening 16 in the utensil supporting plate 2 is preferably provided with aremovable grid indicated by the numeral 42 n ea h gr wa ate p urali y cf lit) intersecting bar members 43 of which there may be any desired number, and the bar members at their outer ends are recessed'or notched as at 44, so as to adapt said ends to fit over the upper surface of the said plate 2 at the circumference of the openings 16 and against the flanges 17 as clearly shown in Figure 2 of the drawings.

It will be understood, of course, that any of the ordinary types of ovens may be employed in connection with the stove.

Having thus described the invention, what I claim is:

1. A cook stove comprising a utensil supporting plate having a burner opening therein, a horizontally disposed U-shaped burner disposed below the opening, a back plate integral with the supporting plate for attachment to a wall, and hooks secured to the supporting plate and engaged with the bight portion of the burner.

2. A cook stove comprising a utensil supporting plate having a back plate for attachment to a wall, a sheet of heat insulating material'disposed between the wall and back plate and having a portion thereof depending below the back plate, and brackets including vertical portions and horizontal supporting members secured, respectively, to the depending portion of the sheet of insulating material and utensil supporting plates, and brace members connecting the vertical portions and utensil supporting plate.

In testimony whereof I affix my signature.
