To allfwhomitmag/concern.' l'

Be it'kuown that I, GASTON W. MONTGOM- nnr, a citizen of the United States, residingE at Toronto, county of York, Province' of Ontario, Canada, have invented. a certain new and 'useful Improvement in Cooktores, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the samefreference beinghad to the accolti'-l panying drawings, which form a part of this specification.

This invention-relatesto stoves for .cookin which both the heat from argas burner and steam is used to cook with.v y

A still further feature is the transfer of the vapors 'arising from thefoodsand also the steam to the combustion chamber of.the\

gas burner. l l I.

In the drawings: Figure 1, is a vertical section on the line A--A of Fig. 2, a party of the ovens being left in elevation to'show'. the doors. Fig. 2, is a vertical section von the line B-B of Figpl.

A cabinet a is formed preferably of metal and is lined with heat-insulating material, such as asbestos, b. I n my preferred form of construction I support two sheet metal the oven c above the oven d.A Each oven has a door' e which opens downward.y The door e horizontally when it is open. Access may behad to each oven through the-heat-- insulated closures f of the cabinet. .These closures have a bevelediit with the openings. in the cabinet to insuretight-ness when closed.

Two water tanks gare supported in the interior of the cabinet, one adjacent to each oven. -These tanks are fastened to a beveled edge closureJt of the cabinet. The beveled edgeV ts 'into a correspondingly beveled opening -that insures an, air-tight. ft. A drainage cock z' leads from the tankthrough the closure. A nipple 7 protrudes from one trudes from each water tank so that when the water tanks are placed their nipples slide into the over-nipplesto form a pas sage between the oven and water tank, The

nipples stay bolts Z that connect with the sides of the cabinet opposite the sides having the nipples vand by the pipinghereiriafteli described. 1

'A burner is supported; inthe 'cabinet-.by l

legs mi It is formed into three chambers, a gas chamber n, and two air chambers; o,

one above and the other belowthe. gas chamber. The principal source of' fuel for the burner enters the cabinetthrough' the pipe p that leads to the gas chamber n. This pipe-.ju is-controlled on the routside of the.

Acabine-t bythe vai:e q: An air pipe 1' leads from the exterior of the cabinet up to a point above the burner Where -it `divides and..the ytwo branches lead across the burner slightly above' it toapoint beyond the rear wall of the zov'ens, thenhorizontally to the rear of,

the ovens near the bottom. TheV branch 's leads into 'the oven d. vThe branch t leads .l

into' the oven On the opposite sides of the ovens lthe pipe u connects with each oven. and leads'th'erefroni into eachgair chamber o v oit the burner/by branches.

A stack m' is located at the top of the The Vmode-ofoperation is as follows The gas maybe turned on and the burner ignited by opening the closure s of the cabinet. This heats the air inthe cabinet and it rises and'eseapes through the stack a. More air to Vtake its" place is4 drawn through the air piper and the branches -s andt of the same intojthe ovens c .and d. -While passing through thebranches s and t over the burner, -the air- 1s considerably heated so that it i.passes into the ovens-in a. bea-ted condition .Calculated to aid in the cooking. The air passes through the ovens and through the pipe'uv that goes into the 'air chambers o of the burner and furnishes the necessary oxygen for the combustion of the gas entering through. the gas pipep.. Thiscirculation through the ovens carries ofi' ythe'vapo'rs of the foodscooking. Some -of these vapors may be quite combustiblean'd hence fuelis added to the usual fuel supply-for a gas burner. Further, the combustion of these vapors entirely eliminates 'the odors of cook-- ing'. When the cabinet' has lbeen sufficiently heated by the burner, the vx/aten. tanks g,

which are filled with water up to the level of the openingsofthenpples ik, begin to ovens are ppm-ted, by .theinterengaging vgive of steam. This steam enters. the ovens through the nipple connections and is drawn into the circulatory current already d escribed.. This makes a current of steam and highly heated air. The heat of the steam l t penetrates deeply into Vthe food stu and the heated air, while penetrating less deeply,

browns the food nicely. The steam in mixing with the highly heated air and passing i through the heated piping and into the air 10 chambers 0 of'the burner, is superhcated. On account 'of this superheated condition,

when it reaches the burner, the steam is easily disassociated and furnishes fuel for the burner.

i5 What I claim is:

`1.Ina gas cook-stove, a'heat-retainiiig chamber, an oven therein,a gas burner for heating the oven, means for supplying steam to said oven, and means for directing air from the outside of said heat-retainingchamber, conveying it to` where it will be pre-vheated by heat generated by the gas burner and then delivering it to said oven, and means fordirecting Athe steam .'and'heated air from said oven to the combustion chamber of said burner, substantially as described. 2. In a gas cook-stove, a heat-retaining chamber, an oven contained therein, a gas burner for heating the oven, means for supn plying steam to said oven, and means f0r`directiiig air from the outside of said heatretaining chamber,A adjacent to the ame of said gas burner to heat the air andtlien' directing the. heated dir to the oven, and iinally directing said air and said steam Afrom said oven to the combustion chamber of said burner for combustion, substantially as described. I

3. In a cook-stove, the combination of an 40 oven, a burner for heating the same, steam generating apparatus for furnishing steam to the oven, means for hea-ting air, means for directing said heated air from the outside of the oven, through 'the oven where it picks up steam and thence directing the air,

steam and Avapors `ofthe oven to the burner for combustion, substantially as described.

4. In a cook-stove, the combination of an oven, a'burner for heating the same, steam generating apparatus operated by the burner 'for furnishing steam to the oven, and means for directing preheated air into the oven where it picksup steam and vapors and for conducting the same' to the burner for combustion, `substantially as described.

5. In a gas 'cook-stove, a cabinet, an oven therein. a gas burner contained in the cabinet and adjacent to the oven, said gas burner be'- .ing provided With a gas chamber and an air chamber, aga's pipe for supplying gas to the gas chamber, a pipe leading from 'the oven for drawing ott the gaseous contents of the oven and conducting it to the air cham- -ber of the burner, and a conduit for drawing air from the outside of the cabinet, taking it to a position where it will be preheated then delivering it into the oven, substantially as described.

' 6. In agas cook-stove, the combination of a cabinet, an oven supported therein, a water tank also supported in a cabinet, a pipe leading from the water tank to the oven, a gas burner contained in the cabinet and adjacent to theoven, said gas burner being proyided with an air chamber, a fuel pipe for supplying fuel gas to the burner, a pipe leading from the oven for drawing of( the gaseous contents of the oven and conducting it to the air chamber of the burner, and' a conduit for drawing air from the outside of the cabinet, the .said conduit passing adja@
