Applio ation filed June 27,1895x Serial No. 554,237. (No model.)

To all whom it may concern:

Be it known that I, FOLKERT KAEMPEN, J11, a citizen of ,the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented new and useful Improvements in Heating-Stoves, of which the following is a specification.

This invention relates to heating-stoves, and has for its object to provide a heatingsto-ve adapted for burning'either hard or soft coal and in which the smoke and other products of combustion are carried into an auxiliary combustion-chamber and there thoroughly consumed, to augment the heating capacity of the stove and effect an economy in the consumption of fuel, and, finally, to improve the construction and efficiency of this type of stoves generally.

To these ends my invention consists in the features and in the construction or arrangement of parts hereinafter described, and pointed out in the claims following the description, reference being had to the accompanying drawings, forming a part of this specification, wherein I Figure 1 is a vertical central section of my improved stove. Fig. 2 is a top plan view of the stove-base. Fig. 3 is a similar view of the double fire-pot. Fig. 4 is a top plan view taken on the line 4 4 of Fig. 1. Fig. 5 is a detail perspective view of'the hot-air ducts. Fig. 6 is a vertical central section of a stove, showing the invention applied to a double heater. Fig. 7 is a top plan view taken on the line 7 7 of Fig. 6, and Fig. 8 is a'detail view of the hot-air ducts.

Referring to the drawings, the numeral 1 indicates the base of the stove suitably supported upon legs, as usual, and provided with an ash-chamber 2'and at its rear with an airinlet chamber 3 open at its top and bottom. Arranged in the front wall of the base 1 is a draft-opening at provided with draft-controlling means of any usual or desired construction, and which'I denominate a blast-draft.

Secured to the upperportion of the base 1 immediately above the ash-chamber 2 is a grate 5. Supported upon and suitably secured to the base 1 is a double fire-pot 6 comprising a front fuel-chamber 7 and a rear aux- .chamber iliary combustion-chamber 8, said chambers being open at both top and bottom, the fuelchamber 7 resting immediately above the grate 5, while the bottom of the auxiliary combustion-chamber rests over the air-inlet ble fire-pot 6 and over the fuel-chamber 7 is a cylindrical or other suitably-shaped drum or casing 9, provided at its front with a draftopening 10, provided with any suitable draftcontrolling device, and which I denominate a combustion-draft. Arranged in the drum or casing 9 is a magazine 11, which at its upper end is closed by a lid or cover 12, as usual. Arranged within the auxiliary combustionchamber- 8 are two hot-air ducts 13, said ducts communicating with each other at their lower ends and having a common inlet 11. The said ducts are fitted in the lower open end of the auxiliary combustion-chamber 8, the inlet 14 registering with the upper end of the airinlet chamber 3 in the base 1. The ducts 13 extend up through the auxiliary combustionchamber, and at their upper ends communicate with two grated openings 15, formed in a cover 16 fitted over the upper end of said auxiliary combustion chamber. The said cover 16 is provided with a centrally-arranged opening 17, constituting a smoke-exit for the auxiliary combustion-chamber, and over said opening is arranged a smoke-exit flue 18, provided with a check-draft 19, and at its upper end is adapted to be connected to a stovepipe.

The operation of the stove constructed as above described is as follows \Vhen the stove is charged with fuel the surface of the latter will be in a plane slightly below the combustion-draft 10. Air is admitted beneath the grate 5 through the blast-draft 4 and passes up through the burning fuel, and at the same time air is also admitted above the fuel through the combustion-draft 10, forcing the flames, smoke and products of combustion backward and into the auxiliary combustionchamber, where the smoke and gases are burned and pass off through the smoke-exit flue 18. The heat, flames and burning gases in their passage into and through the auxiliary combustion-chamber pass between and Seated upon the top of the douupon both sides of the airducts 123, and the cold air drawn up through the air-inlet chamber 3 in the stove'base passes up through said air-ducts, wherein it is heated to a high temperature and discharged through the openi n 15 into the room.

liy means of the cheek-draft 19 air may be admitted for additional combustion if found desirable or as circumstances may prove advisable, owing to the different draft of ditl'erent lines, or for other reasons.

In a stove such as described soft coal may be burned equally as well as hard coal, for not enough heat is generated in the heater containing the magazine to cause the soft coal to coke, the greater portion of the heat beinggenerated in the auxiliary comlmstion-cliamber.

Although I have shown and described the stove as being a magazine-stove, it will. be manifest that the magazine may be omitted, converting the stove into a surface burner.

llymeans ot' the double ii repot, comprising the i'uelchamber and the auxiliary heatingchamber, and by admitting air through the fuel from beneath and over the fuel from above, the greater portion of the heat is generated in said auxiliary combustion-chantber, and the smoke and products of combustion are not only consumed, but aid in inereasingthe heating capacity of the stove.

l'nliigs. (l to 8 I have illustrated myinyention as applied to a double heater or stove designed for conveyin a portion oi? the heat to another room or portion of the building.

The principle of operation in this stove is precisely the same as that before described, the construction of the hotair ducts only being slightly altered. As shown, the hot-air du ets l 3" are bent forward slight] y into the forward combust:ion-chamber and at their upper ends are united to form a single duct 13, that passes up through the stove drum or casin and passes out through the upper portion thereof, where it connected to one end of a hotair pipe 20 that leads to another room or to another portion of the building. lhe hotair pipe 20 at its upper end is provided with a register-valve i l, by means of which the amount of hot air permitted to escape into the room may be regulated. The openings 15, heretofore described, are closed by any suitable or desired means, when the stove is used as a double heater, to prevent the escape of products of combustion into the room.

As before stated, the operation of the double heater is precisely the same as that first described, and from said. description will be readily understood.

llaving described my invention, what I claim is 1. In a heating stove, the combination with a base, of a double ii re pot comprising a fuel chamber and an auxiliary combustion chamber arranged one in front of the other and communicating with each other, hot air ducts arranged in said auxiliary combustion chamher and communicating at their opposite ends with the atmosphere outside the stove,a smoke exit for said auxiliary combustion chamber, and a stove drum or casing arranged oyerthe fuel chamber, whereby the smoke and gases generated in. the fuel chamber pass into the auxiliary combustion chamber and are there consumed and heat the air in its passage through the hot air ducts, substantially as described.
