GAS-STOV E.

SPECIFICATION forming part of Letters Patent No. 443,088, dated December 23, 1890. Application tiled April l, 1890. Serial No. 346,211. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, JOHN W. DANFORTH, a

i citizen of the United States, residing in Bufreference being had to the accompanying" drawings, in which- Figure l is a front elevation, the verticallysliding oven-door being omitted. Fig. 2 is a side elevation. Fig. 3 is ahorizontal section on line a. b, Fig. l; and Fig. 4 is a sectional elevation in or about line c d, Fig. 1, through the water-reservoir and dues. Fig. 5 isa horizontal section in or about line a Z7, Fig. l, the vertical walls of the oven being omitted, so as to show the openings in the table 3a, which register with the vertical passages through the oven-walls.

In said drawings, l represents the, baseframe, upon which the burners, oven, water heater or reservoir, and other parts are supported. This frame-work is preferably constructed of cast-iron, as the cheapest and most suitable material, and is provided with a series of slideways 2 to receive the removable shelves 3 and with a top 3. The shelf 3 is used for pots and kettles or other like purposes. The shelf 3 forms a part of the case surrounding the burners 26,the object being to retain the heat and gases and cause them to go upward through iiues, and to prevent them from coming out into the room.

On the top of the lower or supporting frame I is secured the upper frame-pieces i by the bolts 5, which-pass through the top 3n and then into the lower frame. This upper frame is so formed at the top as to embrace and hold the water-reservoir 6, substantially as shown in Figs. l and 2,and itis provided with slideways 7 and 8 to receive one or more shelves 9 and l0. The shelves 10 or the shelves that go on the slideways 8 are used for warming plates or other analogous purposes.

It will be noticed that the height of the oven can be adjusted by placing the shelf 9 on either of the slideways 7.

In baking some things a quick heat is required; this can be done by contracting the size of the oven. Again, some things are better done by baking them by heat applied at the bottom iirst; this can be done bythe heat from the burners 26, after-which the burners 3i can be started, which will give the necessary heat at the top when the shelf 9 is removed. The upper ring-shaped portions Il receive and hold the water-reservoir 6, the ends of which pass through them, as shown in Figs. l and 2.

Around the reservoir 6 is a jacket of sheet metal l2, which passes up from the point 13 to the back part of the top le, and is provided with an outletor ventpipe l5. A back plate of sheet metal 1G covers the back from the point 14 down to the table 3, This construction leaves a due 17, surrounding the waterreservoir 6, substantially as shown in Fig. 4.

The water-reservoir may be made of plate copper, or of any suitable well-known material, and, if desired, it may be made up of a series of coils of pipe in any well-known way; but the construction shown is preferred. It is provided with inlet-pipes 1S and outletpipes 19. (Shown in Figs. 1 and 2.)

The oven consists of the three double walls 20, 21, and 22 and a vertically-sliding door 23, adapted to slide up and down in the vertical grooves 24C. (Shown in Fig. 3 and by dotted lines in Fig. l.) This sliding door 23 is of the same height as the swinging door 22, which extends up to the line or point 40. (Shown in Fig. l.) The object of this construction is to leave room to'withdraw the broiler 37 and its shelf 3G, when required, and to leave the door 23 only high enough to just pass above the shelf 9, which act-s as the top of the oven, and is removed when it is required to use the upper burners 34 and lower burners 26 either separate or together while the oven-door is closed. In Fig. 2 the door` 23 is shown as raised up to the top of the slideway, and in Fig. 4 it is shown as nearly down IOO to its place. This door 23 when closed is never high ei'lough to cover or inelose the burners 3l, so that sufficient air is at all times admitted thereto. rlhese double walls form lues 25, through which the heat and all the products ol combustion from the lowerburners 2G (which are placed below the table 3, as shown) pass up around the oven through the flues 25.

XVhenever it becomes necessary to use the whole top of the stove without the oven for cooking or other purposes, the double partition or wall 92, which is swung on hinges 27, (see Fig. 3,) is turned back into the position shown by the dotted lines 28 in said Fig. 3, thereby leaving the whole top ot the stove to be used when the oven is not required.

When the wall or partition 22 is closed, as shown in Figs. l and 8, it is secured in that position by putt-ing in a shelf l0 on either of the slideways S.

The shelves 3, fl, and l0 are easily removable, being made so as to be slid in on the various slideways 2, 7, and S.

The burners 2G are connected by pipes l0 with the air-mixers 3l, which receive the heating-gas through the tube 32, the ilow of which is controlled by the stop-cocks Z325.

Just below the water-reservoir are two burners 34 and 35, each of which is provided with an air-mixer 3l, and a stop-cock 33, for controlling the How of gas.

Below the burners 3l is a shelf Se', upon which is placed a meat-broiler or toaster 37. Both the shelf and the broiler or toaster are easily removable when required.

By this construction ofthe stove it will be seen that nearly all the heat from the burners or from the operation of the stove will be caught within the jacket l2, and is thus utilized in heating the water-reservoir l) after having done its work below either in cooking or baking.

39 in Fig. l represents the end of a trough to catch any drip that may come from the boiler. It extends the whole length of the boiler.

In Fig. 5, 25 represents the openings through the top plate 3*, which register with the passages for the products of combustion through the walls 20, 2l, and Q2, said walls being omitted in said Fig. 5, so as to show these openings more clearly.

I claiml. In a gas cooking-stove, the combination, with the upper and lower supporting-frames, of a warming-chamber at one side of the stove, an oven located at the opposite side, composed of double walls forming iiues through which the heat passes, a sliding door forming the front removable side of the oven, a removable shelf D, forming the top of the oven, a waterreservoir located in the top of the upper frame, a jacket inclosing the waterreservoir and forming a flue between it and the reservoir, and a series of burners located below the stove-top, from which the heat passes to the warming-chamber and to the oven-ilues and water-reservoir, substantially as described.

2. In a gas eooking-stove, the combination, with the other walls of the oven, of a hinged wall forming one wall thereof, adapted to be thrown back to one side so as to expose the whole top of the stove for use, substantially as described.

3. In a gas cooking-stove, an'oven consisting of three hollow walls open at the top and bottom, one of the walls being hinged so as to be thrown back to expose the whole top of the stove, and a sliding door adapted to slide vertically in slideways in the two opposite walls, substantially as described.

el. A gas cooking-stove consisting of three sections-a lowerseetion, in which the burners are located, a section in which the oven and warmi11g-chambers are located, and top section, in which isloeated the water-reservoirsubstantially as and for the purposes described.

5. A gas cooking-stove having the waterreservoir located at the top and an intermediate cooking and baking section below it, a series of burners located below the intermediate section, and a means for admit-ting or shutting off the gas, whereby the heat after being used in the cooking and bakingsection passes up tothe water-boiler, substantially as described.
