STOVE OR FURNACE.

SPEdIFICATION forming part of Letters Patent No. 687,549, dated November 26, 1901.

Application filed December 31, 1900. Serial No. 41,615. (No model.)

To all whom it may concern:

Be it known that I, JAMES WILSON, of the city of St. Louis,.State of Missouri, have invented certain new and useful Improvements in Stoves or Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to stoves or furnaces; and it consists of the novel construction, combination, and arrangement of parts here inafter shown, described, and claimed.

The object of this invention is to'provide an improved stove or furnace having means for creating either an up or down draft.

Another object is to provide a stove or furnace constructed so that the fire can be started below the fuel by means of an updraft and after the fuel has become ignited it can be inverted within the fire-pot, placing the fire above the fuel, and a downdraft created, thereby consuming a maximum portion of the gases and radiating greater heat with a small amount of fuel than is given by an ordinary stove using a larger amount of fuel.

Another object is to provide a reversible fire-pot which may be operated after the fire has been started to overturn the fuel contained therein, bringing the fire to the top, so that the flames will pass through the fuel when the downdraft is created.

Figure 1 is a vertical sectional view of my improved stove, taken on the line 0 c of Fig. 3. Fig. 2 is a vertical sectional view taken on the line at d of Fig. 4 substantially at right angles to that shown in Fig. 1. Fig. 3 is a horizontal sectional view taken on the line a a of Fig. 1, and Fig. 4 is a horizontal sectional view taken on the line b b of Fig. 2.

Referring to the drawings in detail, 1 indicates the wall of the stove, leading through which are two openings 2, one of them near the top-of the stove and the other near the bottom. The pipe or flue 3 is rigid with the wall of the stove for receiving the products of combustion from the openings 2 and conveying them to any suitable outlet. Rigid with the wall 1 of the stove, a suitable distance above the bottom, is an interior flange 4, extending entirely around the inner side of the stove and supporting the grate 5. The said grate 5 is arranged in the form of a bowl the stove, one of said trunnions projecting outwardly and adapted to receive a crank 9, whereby it can be inverted whenever it is desired to create a downdraft within the stove. The said fire-pot is provided with short-projections 10, which operate between the bars of the grate 5 and assist in guiding the firepot around into the required position whenever it is operated by the crank 9. v

The stove is provided with a door 11, leading from which is a chute 12, which extends downwardly within the stove and terminates above the fire-pot 7. The purpose of the chute 12 is to receive and guide the fuel into the firepot. Leading from near the top of the stove is a draft-passage 13, which extends downwardly and has its lower end bent inwardly above the fire-pot in order to guide the draft so that it will pass through the fire. The said draft-passage is provided with a slide-damper 14, whereby it may be closed whenever it is desired to use the updraft or to cutoff the supply of air from the interior of the stove. It will be noticed that the draft-passage 13 is located at the side of the stove and has its lower end extended out near the center of the stove and terminating directly above the firepot. This arrangement leaves a freer space for the updraft and does not interfere with the passage of the smoke to the upper outlet when the updraft is used.

The stove is provided with the usual ashpit, having an ordinary door 15, provided with openings and a slide-damper, whereby the passage of air or draft may be admitted or cut off, as required. Above the ash-pit is a guide 16 for receiving and guiding the ashes into the ash-pit. I

17 indicates a valve for closing the opening 2 at the top of the stove, and 18 denotes a damper for closing the pipe 2 at the bottom.

In using my improved stove or furnace the fire is started within the fire-pot by means of an updraft, the air passing through the ashpit and upwardly through the fire-pot and fuel and the products of combustion passing out through the opening 2 adjacent to the top of the stove, the valve 17 being left open to permit the passage. The valve 14 is closed to shut out the air from the draft-passage 13 until the fuel becomes thoroughly ignited, after which the openings through the door 15 are closed and the valve14 is moved to admit the air into the draft-passage 13. The valve-17 is moved to close the opening 2, and the damper 18 is opened to allow the draft to pass out through the outlet. The crank 9 is then turned to reverse the fire-pot 7, which, as above stated, is pivotally supported within thegrate, which operation brings the fire above the fuel and causes the flames to pass through the fuel as the airis admitted through the downdraft-passage 13. The flange 14 provents any of thegases from passing around and above the fire-pot, so that a maximum portion thereof will be consumed by the flames which pass downwardly through the fuel. This results in greater heat being radiated from asmall amount of fuel than can be generated by an ordinary stove using a larger amount of fuel.

The stove is simple in construction, easily operated, and is devoid of all useless appurtenances'.

I claim- '1. A stove having a grate in the form of a bowl, a reversible fire-pot, supported within the grate,.a draft-passage leading from the top atone side of the stove. and terminating near the center of the'stove above the fire- .pot, a pipe 3 atone side of the stove,- openair and smoke through the pipe, and. means for turning the fire-pot as required when an assi n;

up or down draft is used, substantially as specified.

2. In a stove, a grate in the form of a bowl, a fire-pot located therein, a downdraft-passage leading from the top of the stove at one side thereof and terminating near the center of the stove above the fire'pot, a pipe at one side of the stove, an opening leading into the pipe below the fire-pot to be used as a passage for the smoke when a downdraft is ad'- mitted, a damper for controlling the passage of the smoke and air through the pipe, a second opening above the fire-pot to be used as a passage for the smoke when an updraft is admitted, and a damper for controlling the passage of the smoke and air through the said opening, substantially as specified.

3. A stove having a grate in the form of a bowl, a fire-pot located above the grate, a fuel-passage leading from the feed-door'and communicating with the fire-pot, a downdraftpassage leading from the top at one side of the" stove and terminating near the. center thereof above the fire-pot, a flue at one side of the stove, anopening leading into the flue below the fire-pot to be used-as a passage for the smoke when a downdraft is admitted, a damper for controlling the passage of the smoke and air through the pipe adjacent. to the said opening, a second opening above the fire-pot to be used as a passage for the smoke when an updraft is admitted', a damper for controlling the passage of the smoke and air through the said opening, and means for rotating'the fire-pot as required when an up or down draft is admitted, substantially as In testimony whereof I'afli x my signature in presence of two witnesses. ings leading from the stove into the said pipe, dampers for controlling the passage of the JAMES WILSON.- W itnesses:

ALFRED A. EIcKs, JOHN C. HIGDON.
