STOVE.

Specification of Letters Patent.

Patented Jan. 7,1913.

Application led April 22, 1911. Serial No. 622,677.

Ee it known that l, Gaone-n T. Ootnsr, a citizen of the United States, and a resident of Frankfort, in the county of Clinton and State of indiana, have invented a new and lmproved Stove, of which the following is a full, clear, and exact description.

My invention is an improvement in heating stoves, and is so constructed as to provide for the continuous tlow therethrough of air from the room which is to be heated.

it also includes means for causing the soot to be deposited in the top of the stove instead of being carried into the pipe, and in such a way that the soot so deposited will be burnt up and destroyed when the stove is in use.

Reference is to be had to the accompanying drawings forming a partI of this specification, in which the same characters of reference indicate the same parts in all the views.

Figure 1 is a vertical longitudinal sectional view of my improved heating stove; Fig. 2 is a top view thereof, the cover being broken away to show the interior; Fig. 3 is a transverse horizontal sectional view on the line 3 3 of Fig. 1; and Fig. 4 is a transverse horizontal sectional view on the line 4 4 of Fig. 1.

My improved stove comprises an ash chamber 1, resting upon legs 2, and having a door 3 in the front, through which the ashes can be removed. From the top of the ash chamber rise the walls of the tirepit- 4. This iirepit is lined around the sides with firebrick or other refractory material, shown at 5, and has a grate 6 at the bottom, separating it from the ash chamber 1. At the top, the walls of the iirepit are bent outward and then downward, forming the ange 7, which is riveted, or secured in any other suitable manner, to the sides of the body of the stove shown at 8.

Inside the body S of the stove is a bellshaped member S, which depends from the top of the stove, and has its open bottom spaced a suitable distance above the top of the iirepit 4. rlhis bell-shaped member 8 has inner and outer annular walls 9 and 10, forming an inclosed annular space 11, w'hich is shut in at the bottom, but which is open at the top. The closed bottom of the space between the walls of this bell-shaped member 8 communicates through a series of short tubes 12, with the atmosphere, these tubes passing through the outwardly-bent hori- Zontal portion 7 of the walls of the ashpit 4. These outwardly-bent portions 7 form the floor of the heating chamber of my improved stove. The sides of the body of the stove 8 extend downward past the flange 7, but are spaced from the outside of the firepit 4, and terminate above the ashpit 1.

13 is a door located between the top of the firepit and4 the bottom of the member 8', through which fuel can be shoveled when the tire is burning. This door may be made higher if desired, and the front of the bellshaped member 8 can be cut away adjacent the door 18 accordingly. The top of the stove 15 is a hollow box-like cover having an inwardlyextending flange 15 on its lower end, which is open, this iange fitting around the top of the body 8, and the open bottom of this cover permitting free communication between the interior of the cover 15 and the annular space 11.

16 are perforations around the sides of the cover to permit the heated air to pass into the room. Inside of the bell-shaped member 8 are a number of screens 14, supported. around their edges by the inner annular wall 10.

17 is a flue communicating with the upper part of the space between the body 8 and the Y outer wall 9 of the member 8.

In operation, when the fire is burning, the smoke and soot will pass upward into the interior of the bell-shaped member 8 and be reta-ined by the screens. The ascending gases will curl around the bottom of the bellshaped member 8 and pass up between the side of the body 8 and the outside of the wall 9 and out through the flue. The pipes 12 and the walls 9 and 11 will be thoroughly heated by hot gases of combustion, and the air from the room will pass upward through the pipes 12, the annular chamber 11 and out through the openings 16, becoming thoroughly heated in its progress. Thus, cold air will be taken from the lower part of the room and heated, and allowed to pass out through the upper part of the stove toward the top of the room, providing for an efficient and continuous circulation, which will raise the apartment to a uniform temperature throughout.

l have found this stove a very practical construction fo-r the burning of soft or bitumino-us coal. rlhe soot and smoke which are given off by soft coal are mostly deposited on the screens 14, and the lower part of the walls of the bell-shaped member 8. rllhis is because the open lower end of the bell-shaped m-ember S is directly above the firepit et, and the gases of combustion tend to pass straight up into the interior of the bell-shaped member 8. @n account of this bell-shaped member 8 being closed at its upper end, these gases curl back on themselves and pass around the lower edges of the bell-shaped member, and then upward and out through the flue 17. lfhile the gases follow this circuitous course, the soot they carry is sifted out by means of the screens la, and is also deposited to some extent on the inside and bottom of the bell-shaped member 8. The hot gases of combustion rising from the iirepit et tend to burn away the soot and smoke, and thus malle the stove automatically clean itself. Hence, the flue 17 does not readily become choked up with dirt, and it is possible to use my stove a long time without the sam-e requiring to be cleaned and overhauled.

lit will be seen that the bell-shaped member 8 flares downward, making the space between this bell-shaped member and the body 8 widest at the upper end of the stove. This minimizes tho dang-er of soot and smoke clogging the upper part of the body 8, and preventing the products of combustion from passing out through the flue 17.

By locating the bell-shaped member 8 having the annular air heating chamber formed by its walls, with its interior directly above the iirepit and in line with the hot gases that are formed during the process of combustion, this annular member is heated both inside and out by the gases which pass up into the same and are then forced to curl back on themselves before passing around the lower edge of the bellshaped member. This results in a great deal more heat being imparted to the air passing into the annular air chamber 11, and atvthe same time gives a more perfect combustion of the fuel. This is because much of the soot which would pass out through the chimney 17, if the gases tool; a straight direct course through the stove, is deposited on the screens and the sides of the bell-shaped member by the gases in their circuitous course through the stove and out; and much of this soot is subsequently burnt up by the action of the gases which rise from the fire as the process of combustion continues.

Having thus described my invention, claim as new and desire to secure by Letters Patent:
