' To @ZZ whom t may concern.'

oil burning A further object of the invention is to provide a gas generating drum centrally lccated within the stove in which the oil is fed into the drum from the top when it drops on a conical heated plate where it is vaporized and the vapor collected within the drum where it is preheated before being mixed with air for burning in an inverted burner.

Another object of the invention is to provide a stove having an external heating chamber around the air inlet and a gas generating drum and chamber within the air chamber, the oil feedv pipe entering from the top so that the oil will be converted into gas and the gas and air thoroughly heated before being mixed for burning.

Still another object of the invention is to provide a stove with anv air inlet and a gas generatingchamber, wherein the gas from a narrow annular opening at the bottom of the gas generating chamber and heated air are drawn through narrow adjacent concentric openings by the draft in the heat:

ing chamber which is concentric to the air and gas generating'chambers, so that the gas will be drawn outwardly from said annular opening in the gas chamber and will be mixed and burned with the air as itpasses under the annular adjacent air opening,they

flame and heat passing outwardly concentrically into theheating chamber.

The invention also comprehends other improvements in the particular constructionv and arrangement of parts which will be more particularly pointed out in the specication and claims.

In the drawings:

Figure 1 is a vertical sectional view through the stove.

Fig. 2 is a transverse section on line 2-2 of Fig. 1. Y

Fig. is a partly disassembled view.

1 indicates a casing or stove body which forms a heating chamber 2, the casing bcing provided with an opening 3 for the liuc pipe 4, and being supported on legs 5.

cylindrical member 6 is mounted in the casing 1, at the top thereof, and forms an air heating chamber 7. A tubular member 8, is mounted within the cylindrical member, and spaced therefrom, on an inclined dellector 9, attached to the cylindrical member, and extending from the tubular members beyond Said cylindrical member into the heating chamber. The tubular member has the upper end closed by a cover 10 and is provided near the bottom with a series oi openings 11.

A drum 12 is removably and adjustably mounted within the tubular member, having the upper end closed, and the lower end open and terminating near the lower open end of the tubular member to form an annularv air passage into a combustion chan ber 13. The drum is provided with an external flange 12 near the lower end contacting' with the tubular member to form a dead air spacebetween the drum and the tubular member above the flange. An oil supply pipe 14 is connected to the top of the drum, communicates therewith and extends upward through the air chamber and has a funnel 14 secured to the top thereof. A rod 15 adjustably mounted in the drum has a conical' plate 16 secured thereto so that the bottom edge is adjacent the bottom edge of the drum but capable ci' adjustment with respect thereto. The conical plate forms an annular gas passage with the drum to the combustion chamber 13, adjacentv the annular air passage. A drip pan 17 is adjustably secured on rod 15 below the conical plate 16 and forms a container for-holding a starting charge. The drum 1,2, drip pan 1,7 and attached parts are removable irom the stove as is shown in Fig. 3 for cleaning purposes.

A cover or damper 18 is adjustably mounted to open or close the air chamber '7 as indicated at 19.

A partition 23 is placed in the bottom of the stove and a false bottom 24 is carried thereon, the combustion chamber 13 being formed between the false bottom and the inclined deiiector 9. The space below the false bottom is filled with sand as indicated at 25. When the parts are in place the drip pan 17 rests on the false bottom.

The body of the stove isprovided with a door 26 for access to the combustion chamber so the starting charge may be ignited or the flame observed.

,To use this stove, a starting charge, for

instance, gasolene is poured into the funnel at the top and the fuel runs down into the pan 17, and is ignited through the door 26.

rlie air for the combustion of the gasolene comes in at the top of the stove and through the air. chamber 7 down around the tubular member S, passes through the openings 11 and the annular air passage when it mixes with the gasolene vaporto form a combustible charge. The flame passes outwardly around the deflector and the exhaust gases pass up through the heating chamber and out the flue pipe 4f.

The heat of the starting charge warms the conical plate 1G and the cylindrical member 6, so that the air in the air chamber ,7is warmed, 'andV oilfed into the funnel 19 at vthe top of pipe 14; is warmed and is evenly distributed over the conical plate 16' on which it is vaporized, filling the drum 12 with vaporized gas, which becomes further Vheated and passes out the annular gas passage tothe combustion chamber. The draft in the Aflue draws this gas outwardlyI 'from the gas passage uniting with the air coming through the air Apassage' and beginning to burn. The fiame passes out around the deflector andV up into the heating chamber.

After the starting charge has burnt out,

the gas from the drum continues to burnv 'beginning adjacent the lower edge ofthe wall oi drum 12. Y

The supply of ifuelA may? be regulated from some external source and the air supply is regulated by adjusting the Vdamper 18 at the topV of the airchanfiber.v rlhis regulation of air and oil permits ad? justinent to obtain a perfectly'combustible mixture. To 'further obtain adjustment ior the latter purpose the conical plate 16, and

the drum 1 2 are adjustably constructed, s

that relative adjustment may be had be-- tween the plate 1G and the drum; and the drum` and tubular member.

' In the construction as shown itffwill be obvious that the' air chamber and gas'geii'er-- yatiiigdrum are' positioned in the center of the heating chamber, so -that thev incoming Vair and thevgas in the drumM will be preheated before' passing out of theY annular openings at the bottom to encourage a complete combustion of the gas. 1

It willalso be noted that the dead airv vspace formed above the drum preventsY the cool air in the top ofchamber 7 fromcool ing the gas in the drum.
