HEATING-STOVE.

To all whom it may concern: I

Be it known that I, ELI JACKSON PARKER, a citizen of the United States, residing at Florence, in the county of Lauderdale and State of Alabama, have invented certain new and useful Improvements in Heating- Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to stoves and more particularly to heating stoves and is designed as an improvement on the stove shown and described in my Patent 1,015,973, dated January 80, 1912.

The object of the invention is to improve 7 the construction of a stove of this character in such a way that air admitted from a point close to or below the floor of the apartment in which the stove is situated supports the combustion and also furnishes the air to be heated by the stove and passed out into the surrounding atmosphere, the air being divided by and withinthe stove structure so that the products. of combustion are passed up through the smoke flue to the chimney and the heated fresh air is delivered into the apartment.

Another object is to provide improved means for separating and controlling the air for combustion and the air to be heated and discharged into the room. I

WVith the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

. In the accompanying drawings: Figure 1 represents a side elevation of a stove 0on structed in accordance with this invention,

a side elevation or edge view thereof; Fig. 12 is a transverse section taken on the line l212 of Fig. 10; Fig. 13 is a plan View of the plate which separates the air dividing chamber from the receiving chamber; Fig. 1415 an edge view thereof; Fig. 15 is a transverse section taken on the line 1515 of Fig. 13; Fig. 16 is a plan view of the base plate; Fig. 117 is a transverse section taken on the line 17-47 of Fig. 16.

In the embodiment illustrated, this improved stove is constructed of the following instrumentalitiesto wit: a base B having an inlet I, an ash pit casing A superposed upon the base, the grate G, the firepot P above the ash pit and extending into a central opening in the upper end thereof, and a chamber C above the fire-pot, these three members being surrounded by a shell S rising from the base and supporting the top T of the stove in the rear of which is an outlet O leading to the smoke pipe 70 and on which is supported an outer cylindrical skirt S. Connected with the smokepipe p is a foul air or ventilating pipe V. A flue F leads obliquely upward through the fire-pot P, combustion chamber and top .'I and forms a means of communication between the annular space around the fire-pot and the surrounding atmosphere of the stove.

This fine F is constructed in sections, one member F of which is shown cast integral with the fire pot P and extends inwardly and upwardly, through the fire pot from one side wall thereof toward the top with its free end terminating below the. top of the fire pot to provide for its protection against breakage when packed for storing or shipping. The intermediate section F connects the fire pot section with a top section F carried by the top T and which is here shown cast on the lower face of said top and extended obliquely in alinement with the pot carried section F. Air receiving and dividing chambers 1 and 2 are formed between the base B and a horizontal ring-shaped partition 3 snugly surrounding the fire-pot Pand resting. on the ash pit casing A. The outer edge of the partition 3 bears against the shell S, thus retaining the fire pot, the ashpit casing, and the base centered rigidly in said shell without the use of fasteners between these parts.

The base B consists of a shallow pan supported above the floor line by legs L and having through its center an opening surrounded by a depending flange 4 which constitutes the inlet 1. In rear of the inlet of this base pan is a cross partition '5'pierced with openings 6 as best seen in Fig. 7.

7 is a damper movable over suitable guides 8 and having openings 9 adapted to be brought into register with the openings 6 in the partition to provide for the admission of more or less air to the space behind the partition for combustion purposes as will be hereinafter described but it is to be understood that this'da-mper has no effect on the amount of air admitted to the space forward of the partition which is the air that is to be heated and finally passed into the room as is also hereinafter described.

Surrounding and connected with the flange 4 of the inlet I is apipe 10 which extends necessarily passed outside of the apartment 2 and 3. The latter view illustrates how this shell at its-front may be provided with doors 12 and 13 for feeding coal and removing ashes respectively. The ash pit casing A rests on a flat horizontal plate 14 which I bears on the upper edge of the pan-shaped base B and forms the top of the air receiving chamber 1 of the base. Said casing A is preferably in the form of a dome as shown. This improved fire pot P is of an inverted truncated cone-shape and extends about two-thirds of the height of the shell S and has an outturned flange P, the edge of which engages the inner wall ofthe shell S and forms a horizontal partition constituting the upper end of the. heating chamber 23 hereinafter described. The smaller end of the fire pot P extends into the casing 15 through the opening in its upper end and snugly fits in said opening andis thus supported insaid casing. connects the heating chamber 23 with the atmosphere extends from a point near the upper end of the fire pot P obliquely through 1 said pot at the rear thereof, so that the air The flue F which" ing is pierced by a plurality of apertures 17 here shown arranged in the form of two vertlcally spaced series extendlng around about one-quarter of the circumference of the dome more or less and which are designed for admitting air for sustainmg combustion to the interior of said casing the side walls and a portion of the ash pit and from which the air passes up through the grateinto the firepot P above foraifording thenecessary draft to the stove.

The plate 14-which forms the bottom ofthe ash pit A and the top'of the air receiving chamber 2 is provided in its periphery at the rear thereof with a plurality of notches 18, see Fig. 3, said notches being arranged close together so that the fingers 181 between them serve to break up the air admitted to the chamber which is formed above the'hollow base. notchespasses into the chamber above the hollow base and passes through the openings 17 in the casing 15 and entersthe ash pit passing up'therethrough intothe fire pot P and is designed for facilitating the combustion within said fire pot; This plate 14 is provided at opposite sides near its front end with two large notches or "recesses 19 and 20 which are designed to admit air to the space between the casing A and the shell S at the front portion of the stove. as is shown clearly in Figs. 6 and 9.

The annular horizontal partition 3 which surrounds the fire-pot Pin contact withthe ash pit. casing A and forms the topor upper wall of the air chamber 1, is provided with'depending legs 21 and '22 arranged at the rear of the notches 19 and 20 and'resting on the top plate 14 of the base B. The

This air admitted through the legs 21 and 22 also contact with the shell S r Y and casing A and thus serve to divide the chamber beneath the partition 3"into compartments, the compartment at the rear between said legs 21 and 22 being in communication with the interior of the casing A through the openings 17 thereof and with the receiving chamber 1 through the open ings 18, the front compartment communicating with the front portion'of the chamber 1 p in advance of the damper 7 and with the space 23 around the firepot above plate 3, the recesses 19 and 20 in said plate 3 providing for this communication and for the passage of the air from the front of the receiving'chamber 1 and of the divided cham ber 2 into said chamber 23.

' The legs 21 and 22 serve not only to divide the space beneath the partition 3 into a pair of compartments, but due to their positioning on opposite sides of said partition out 'i of diametrical alinement, they serve to center the aforesaid partition on the ash pit casing A when assembling the various parts of the stove before applying the shell S. This is essential in order to aline the opening in the partition 3 with the central opening in the top of the casing A in order that the lower end of the fire pot P may be readily inserted through the alined openings. The legs'in question also serve to reinforce and brace the partition 3, as will be obvious from an inspection of the drawings.

The chamber 23 communicates with the surrounding atmosphere of the room by means of the flue F as is shown clearly in Fig. 3 and through which passes the air which is heated in said chamber 23 out into the room for warming the room and supplying fresh air thereto.

The top T is shown provided with an opening T which communicates with the flue F and is provided with a pivoted closure 24 for controlling the dischargeof the heated air from the stove into the room.

The cylindrical skirt S is here shown supported in an annular recess 25 formed on a projecting flange 26 of the top T, said skirt S having an inwardly extending annular flange 27 to eflect said engagement as is shown clearly in Figs. 2 and 3. This flange 27 is pierced by a multiplicity of perforations 28 here shown arranged in two annular series, the perforations of one series alternating with those of the other and through which the heated air which is radiated from the outer face of the shell S is designed to be directed upwardly and discharged into the surrounding atmosphere of the stove. This skirt S is here shown provided in its lower edge with an open slot 29 through which the handle 30 of the damper 7 extends to locate said handle in convenient position for operating the damper to control the amount of air supplied for combustion. To assist in supporting this skirt S, legs 31 are provided which are shown adjustably mounted on the skirt to provide for any unevenness which may exist in the supporting surface or floor f on which the stove is mounted.

The ventilating flue or shown provided with legs 32 adapted to engage the floor 7 and to space the lower end of said flue the proper distance from the floor to provide for the entrance thereto of the foul air which it is well known falls and lies near the floor of an apartment. This flue 82 connects with and surrounds the rear end of the smoke pipe 19 as is shown clearly in Fig. 1 and by so arranging it, the draft produced by the passage of the products of combustion through the pipe 79 into the chimney 0 will cause a draft through the ventilator tube V and thereby suck up the foul air from the floor or near the floor of the apartment in which the stove is located. A damper (Z is shown arranged in the flue V pipe V is also for controlling the suction or draft therethrough. This ventilating flue is especially useful in schoolrooms or. other large rooms where many persons are designed to be assembled and operates in connection with the air circulating skirt S which surrounds the stove, said skirt being spaced from the shell S a suiiicient distance to form a heating and circulating chamber for the air in the room which is drawn up between these members and discharged through the openings 28 at the top of the skirt.

In the use of this improved stove, the fire is built upon the grate G and the live coals stand within the fire-pot P, fresh air being supplied through the inlet I passing through the damper controlled apertured partition 5 throughthe rear portion of the chamber 1, up through the openings 18 in plate 14, through-the openings 17 into the dome l5 and upthrough the grate G. To increase the draft, the damper 7 is opened more or less and it will be seen that the adjustment of this damper is the only means provided for controlling the burning of the fuel. The

fire thus maintained in the fire-pot P heats the air which is admitted to the front portion of the chamber 1 and passes up around the front portion of the dome 15 through the recesses 19 and 20 in the plate 14 and through recesses 19 and 20 in the plate3 through which it passes to the chamber 23 and is thoroughly heated before being discharged through the fiue F and opening P into the atmosphere surrounding the stove.

Thus it will be seen that a stove is produced wherein the cold fresh air admitted through thev inlet I and finally delivered into the apartment being heated, is warmed three times first around the ash pit, next around the fire-pot and finally within the flue which extends upward through the chamber and top of the stove and may therefore be of considerable length. The outlet of the heated air is controlled by the damper like closure 2%, the closing of which simply shuts off escape into the room while retaining that already heated so that at any subsequent time it may be let out into the room and the latter warmed. It will thus be observed that the passage for the fresh air is entirely out of communication with the interior of the ash pit, being completely separated therefrom by the depending flanges 21 and 22 of the plate 3 so that no dust can get into it and the heated air is delivered into the apartment in a pure condition having been purified at the high temperature to which it is subjected on its way from the inlet to the outlet of the stove.

I claim as my invention:

1. A stove comprising a flat horizontal base, a circular dome-like ash pit casing disconnected therewith but resting thereon a distance from the edge thereof, said casing having in its upper" endv a central circular opening, a fire pot having its lower end in 2. A stove comprising afiat horizontal base, a circular dome-like ash pit casing disconnected therewith but restingfthereon a distance from the edge thereof, said casing having in its upper end a central circular opening, a fire pot having its lower end inserted snugly in the aforesaid opening, a shell rising from the base and surrounding the ash pit casing and the fire pot in spaced relation thereto, a horizontal centering ring resting on said ash pit casing, snugly surrounding the fire pot, and contacting at its Copies of this patent may be obtained for outer edge with the shell, whereby to retain .the fire pot, the ash pit casing, and the base in proper rigid relation without the use of fastening means between these parts, a pair of spaced legs formed integrally with the ring and depending therefrom to the base A air heating compartments surrounding the f;

casing, air inlets into said compartments, an a1r outlet from one compartment into said casing, an outlet from the other lnto the space above the ring and around the fire pot, and a hot air outlet from such space.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ELI JACKSON PARKER.
