SPECIFICATION forming part of Letters Patent No. 668,599, dated February 19, 1901.

Applicationled November 2l, 19,00. Serial No. 37,209. (No model.) l

To if/ZZ whom t may concern.-

Be it it known that I, GEORGE F. BROTT, a citizen ofthe United States, residing at Washington, District of Columbia, have invented cert-ain new and useful Improvements in Cooking Stoves or Ranges, of which the following is a specification.

My invention is designed for the production of a cooking stove or range adapted to Io employ either coal or Wood or gaseous fuel and in which the heat generated may be utilized for cooking purposes and for the heating of a house by a hot-water system.

The primary object of my invention is to provide a combined cooking and house-heating stove or range which will enable a separate furnace in the cellar for the heating of the house to be dispensed with.

A further object of the invention is to prozo vide means whereby coal or gaseous fuel may be independently employed for cooking and heating purposes'and whereby gas may be used during warm weather for cooking purposes independently of the house-heating system.

Other objects of the invention will hereinafter appear, and the novel features thereof will be set forth in the claims.

In the drawings forming part of this speci- 3o fication, Figure 1 is a vertical transverse section of a stove or range constructed according to my invention. Fig. 2 is a top plan view of the same, and Fig. 3 is a similar view of the Water-tank or boiler. Like reference-numerals indicate like parts in the dierent views.

The shell of the stove is made up of the sides 1, the bottoni 2, and the top 3, all suitably secured to each other. The sides 1 are provided with openings or ports 4 near their upper ends and are inclosed by a casing 5, secured at its upper end to the top 3 and having its lower end open. In ythe top 3 are formed a series of rows of pot-openings closed by the removable lids 6 6 7 7 8 8, preferably arranged parallel to each other.

Secured within the stove, at a point intermediate its top and bottom ends, is a watertank or boiler 9, the same being provided with water-legs 10, which extend down to and 5o rest upon the bottom 2. These water-legs 10 are formed with inwardly-extending lugs 11, which support a grate 12, of ordinary construction, extending clear across the stove.

Formed in the tank or boiler 9 at points di- 55 rectly beneath the lids or covers 6 and 8 in the top 3 are tubular passages 13 13, in which lit the dues 14, the same extending vertically therefrom and terminating at their upper ends a short distance below the lids 6 and S. The 6o passages through the lues 14 are controlled by dampers 15, mounted above the upper ends of said iiues and connected lo operatingrods 16 16, extending out through the front wall of the stove. By moving these operating-rods in one directionor the other the damper-s 15 may be moved to a position directly over the flues 14 or to a position out of linel therewith. Of course when said dampers are directly over the flues 14 the pas- 7o sage therethrough is closed, and When they are out of line with said dues the passage through the latter is open. The lines 14 project at their upper ends through and are supported by a horizontal partition 17, located a A short distance beneath the top3 of the stove, forming a space 18 through which the products of combustion pass on their way to the chimney 19. Also extending transversely of the stove and located in the space 18 directly 8o in front of the chimney 19 is a partition 20, which serves to deflect the products of combustion entering the space 18 from the lines 14 around the rear ends of the stove, so that they will enter the lower end of the chimney 19 from opposite sides. y

Pivotally mounted in the partition 20 and in the front wall of the stove are rods 21 21, having secured to thenrdampers 22 22, extending longitudinally of the stove in the 9o space 18 and serving to cut off the sides of the space 18 from the central portion thereof. These dampers are located between the central row of openings in the top 3, which are covered by the lids 7, and the outer rows of said openings.

Located centrally of the stove, between the flues 14 on opposite sides of the stove and beneath the partition 17, is an oven 23, the same being supported in any suitable inanner from the water-tank or boiler 9. In this oven is located a detachable gas-burner 2i, connected with any suitable source of supply, and beneath the tank or boiler 9 is a similar gas-burner 25. In the space 1S, directly beneath each of the lids 7 of the central row of pot-openings in the top 3, is a gas-burner 2G, the burners 25 and 2G being also connected with a suitable source et gassupply.

Leading from the upper part of the boiler il is an uptake-pipe 27, and leadinginto one of the legs lOot the tank il, near its lowerend, is a downtake or return pipe 28. The pipes 27 and 2S are connected with the radiators ofthe house-heating system in the usual manner.

In the partition 17, above the burner 24, is an opening or openings leading into the oren 23, controlled by a slide or damper 29. Similar openings are formed in the sides of the oven 25 controlled by the slides or dampers 30.

The operation of my improved stove or range is as follows: When it is desired to einploy coal or other hard fuel in the stove and the stove is to be employed for house-heat ing as well as cooking purposes, a iire is built in the combnstion-chambcr upon the grate l2 and the tank 9, as well as the remainder of the hot-water system, is filled with water. The products of combustion impinging against the under side ci' the tank 9, as well as against the legs l0 thereof, heat the water in said tank, and the same is caused to circu late throughout the piping and radiators in the house, thereby heating the same. At the same time the products of combustion pass up through the ilues li, and thence out through the chimney 19 after passing around the partition 20. The oven is thereby heated not only from the water-tank 9 beneath the same, but from the heat of the products of combustion passing through the fines la. The top of the stove is also heated by direct iinpact of the products of combustion from the fines 14: againstI the under side of the lids or covers G and S. The oven 23 may thus be used in the usual manner for roasting or bak` ing anything that is desired and the top of the stove may also be used for cooking purposes.

It it be desired that the whole of the top 3 of the stove be heated, the dampers 22 are turned to the position shown in dotted lines in Fig. l of the drawings, when the products of combustion from the fines la may pass inwardly to the center of the stove and heat the lids 7 and the interveningspaces between the saine.

The casing 5, surrounding the sides l of the stove, serves to prevent too great a heat adjacent to the stove and also serves to draw in the cold air from the bottom of the room up through the lower open end of said easing, the same passing through the ports or openings 4 into the space 1S, and thence oli? through the chimney li).

Instead of using coal or wood on the grate 12 as the means iorsupplying heat the burner 25 may be utilized, the saine acting upon the water-tank i) and upon the top 3 of the stove in the same manner as the products oi co1nbustion from the burning fuel on the grate l2.

In warm weather when no heating ot' the house is desired the stove or range may be used for cooking purposes by dispensing with the fire on the grate l2 and at the burner 25 and utilizing the burner 24tand 2o'. The burner 2i serves to heat the oven and may also be used as a broiler, whereas the burners 26,' located directly beneath the lids 7 of the openings in the top 5 at the center of the stove, serve to heat said lids, so that any articles of food may be cooked thereon.

The water-legs 10 on the tank 9 may of course be dispensed with, and for said tank I may substitute any other kind of receptacle in which the water may be heated.

following claims I intend that the same shall include such a tank as is specifically shown as well as anyother form of tank, coil ot pipe, and the like.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
