STOVE.

This invention relates-to certain novel and useful improvements in heating stoves and has for its principal object the provision of an improved construction of this character which will be highly efiicient inuse and economical in manufacture.

Among the several objects of the invention is the production of a fuel saving heating stove or furnace.

A further object of the invention is the production of a stove of the character hereinafter described wherein there is provided a simple combination and arrangement of parts for directing atmospheric air'through the combustion chamber of the stove to be expelled therefrom in heated condition to circulate within the room wherein the stove is located and wherein this simple combination and arrangement of parts permits of so the commingling of water vapor with the atmospheric air whereby a certain amount of the water vapor may be admitted into the combustion chamber to commingle with the particles of combustion and generate an inflammable gas wherebv the minute particles of combustion will be entirely consumed before reaching exit through the stove pipe thus reducing the amount of soot or other unburned particles of combustion from collecting in the stove pipe. thus greatly increasing the heating capacity of the stove. A still further object of the invention resides in the novel combination and arrangement of parts for evaporating the water from a humidifying pan wherein this humidifving pan islocated at a. point near or contiguous the fire box of the stove wherebv the heat generating from the fire box will come into contact with thehumidifying pan and generatea water vapor which passes into an air conductor leading through the combustion chamber of the stove.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed. Y

The invention will be understood by reference to the accompanying drawing, i1- lustrating the preferred form of construction. and in which- Fig. 1 is a partsectional side elevational view of the stove or furnace embodying the invention,

Fig. 2 is a fragmentary sectional detail view of the same taken substantially on line 22 of Fig. 1,

Fig. 3 is a view of the sametaken substantially on line 3--3 of Fig. 1, and

Fig. 4 is a fragmentary sectional detail view of the same taken substantially on line 44 of Fig. 1.

In accordance with the several objects of the invention I provide a stove, indicated generally by the reference character A. V This stove includes a base '10 arranged below the fire box 11 within which the fire pot (not shown) is confined. Above this fire box the stove includes a combustion chamber 12 defined by cylindrical side walls 13 within which is formed an opening 14 through which fuel is admitted to the fire pot. This opening 14 is normally closed by a hinged door 15. :The walls 13 support a top wall 16 in. which is formed an opening 17 for reasons hereinafter set forth. This top wall defines an opening 18 around which is disposed an annular ring 19 adapted to receive the stove pipe 20 including the usual damper 21. This top wall 16 supports a conical dc flector dome 22 which in the present instance is provided with a plurality of spaced passages 23. I

Disposed in the combustion chamber 12 is a hot air conduit 24 having one end portion 25 thereof received by the opening 17. This hotair conduit extends through the combustion chamber in an outwardly and downwardly direction and through an opening 26 .wherethe hot air conduit connects with a cold air conduit 27 having an opening 28 formed in its lower end portion for admission of atmospheric air therein to pass through the hot air conduit to be heated by the heat generated in the combustion chamber. This outwardly and downwardly inclined portion of the hot air conduit is indicated at 26' and it is, important to note that this portion of the hot air conduit is disposed directly over the fire pot so that the heat generating from the particles of combustion in this fire pot will be directed into contact with the walls of the hot air conduit at this point.

The cold air conduit 27 has an openin 29 formed therein above which is disposed a shield 30. This shield 30 extends inwardly and downwardly and has its outer edge fragmentary sectional detail portion 31 disposed to rest upon the adjacent top edge portion 31 of a humidifying pan 32. This pan 32 is supported by the 'cold air conduit, between this conduit and the fire box 11 through the medium of a supporting shelf 33 which includes an upturned flange 34 serving to prevent self-displacement of this humidifying pan. This humidifying pan further includes a portion 35 defining a filling neck 36 through which ment, to open and close the opening 40, by

a suitable guiding housing 43 carried by the bottom wall 39 on the inner side thereof. Carried by the portion 26' on the outer side of the bottom wall 39 is a deflector plate '44 defining a passage 45 having communication at one end as at 46 with the hot air conduit 26' through the opening 40. 'The upper end portion 47 of this deflector has a plurality of perforations 48- formed therein opening communication between the passage of the combustion chamber 12.

This arrangement is such that atmospheris air admitted through the cold air conduit into the hot air conduit 26 finds entrance into the passage 45 when the shutter plate 'the production of combustion within the fire pot so that as this heated air is admitted into the combustion chamber 12 through the perforations 48 it naturally follows that this heated air will rise within the combustion chamber into contact with the hot air conduit 24 thereby serving to instantly heat the air passing through this hot air conduit 24 and through the passages formed in the deflector dome. It is also, apparent that with theatmospheric air entering the passage 45 from the cold air-conduit 27 is carried a certain amount of water vapor from the humidifying pan and as this water-vapor is admitted into the combustion chamber through the perforations 48 the moist air will tend to generate an'infiammable gas thereby assuring complete combustion of the unburned minute particles of combustion.

It is important to note that when the shutter is in position to close passage through the opening 40 that the water vapor generating from the humidifying pan will be directed through the hot air conduits 26' and 24 thus permitting a certain amount of nzoisture in the heated air of the room withto those skilled in the art that I provide a stove wherein the heating capacity of the same is greatly increased by reason of the novel manner in which moist atmospheric air is directed through the combustion chamber tobe expelled through the passages formed in the deflector dome.

lVhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
