This invention relates to a liquid fuel trated at 10 in Fig. 1, and having the flue ll, burner, which is particularly adapted to be may be of any conventional construction and positioned in the fire box of a stove, boiler, as the improved burner is to be used upon heating stove, or similar construction. various heating appliances it will be readily An object of the invention is to provide a understood that this stove is shown for purcheap, simple, and durable construction, poses of illustration only and that the use of which will insure safety and which will have the improved burner is not limited thereto. an eflicient and simple operation The burner comprises a receptacle having Another object of the invention is to proa bottom 12, a front wall 13, a rear wall 14:,

In the preferred oiently upon all grades of fuel and which is form of construction therfront wall 18 is so designed that the supply pipe delivering much higher than the rear wall 14 and the fuel to the burner will not be subjected to eX- top edges of the side walls 15 and 16 to slope cessive heat, causing the supply pipe to be downwardly toward the rear wall. This re- 15 kept comparatively clean, without requiring ceptacle is preferably formed of cast iron, cleaning at regular intervals because of the tire clay, or equivalent material, and may be carbon deposited therein. The improved supported in the stove as by fire brick 17, or burner is advantageous in that it may be sucother refractory material. The bottom 12 has cessfully employed when burning wood, or a raised central portion indicated at 18, this similar fuel, and oil simultaneously, thus enpreferably being in the form of a square abling the user to economize on oil fuel when pyramid having upwardly converging sides wood or other fuel is plentiful. 19.

The burner. bafile plate and beads extend from side' to Fig. 3 is a top plan view of the burner. side of the receptacle. I
Referring to the accompanying drawing, The operation and advantages of the im- ,wherein similar reference characters desigproved 'burnerare as follows: The oil or nate similar parts throughout, the stove illusliquid fuel on l avingthe supply pipe is discharged upon the baflie 26 and is caused to flow downwardly thereover in a thin film. The ridges or beads 27 retard the flow of oil to such an extent as to assist in causing the oil to be dispersed over the baffle and flow in the thin film. Any excess oil which should not be vaporized on the baffle 26 drops from it onto the raised central portion 18 which, being relatively liot, will cause the vaporization of the oil to be completed. In many instances the amount of oil which drips down onto the forward side of the raised square pyramid is considerable. The raised central portion being relatively hot assists materially in vaporizing the oil and as the oil flows downwardly and forwardly on the pyramid, it collects at the base of the pyramid. The baffle 26 also serves to direct the incoming air downwardly, causing it'to sweep downwardly near the bottom of the receptacle and pick up the vaporized fuel which results from some of the fuel having dripped ofi of the baffle. This downwardly directed incoming air is directed against the forward side of the pyramid on which oil is being vaporized. This forward sideof the pyramid acts slightly as an obstruction for the incoming air so that the air will be caused to pick up the vapor. The air then sweeps by the sides of the pyramid or between the pyramid and the side walls 15 and 16, picking up vaporized oil which may have collected from flowing off of the forward side of. the pyramid. Most of the combustion takes place near the back of the pyramid in such a manner that a strong continuous draftis automatically produced, causing a continual supply of air to be drawn in through air inlet 20. By virtue of the fact that the air inlet is located very close to the oil inlet, the oil inlet will be kept sufficiently cool to prevent the carbonizing of the fuel and the consequent clogging up of the fuel oil supply pipe.
If'wood or other fuel is burned in the stove, either alone or in'conjunction with the oil, the depressions or recesses around the elevated central portion of the receptacle will receive the excess of ash, the remainder of the ash being swept out of the flue by the current of air entering the receptacle and caused to sweep near the bottom by the baffle 26.
From the above described construction it will be. appreciated that a novel, simple, ef-
f ficient and advantageous burner is provided for handling liquid fuels, which may be easily and quickly installed in heating appliances toconvert them from a wood or coal burning appliance to an oil or liquid "fuel burning construction. The improved burner provides two different vaporization localities, the first being on the baiileplate 26 and. the second being on the elevated central portion 18 of the bottom 12. The ar- -rangement issuchthat the supply pipe is kept relatively cool and the baflie not only serves to spread the oil in a thin film but also serves to direct the flow of air in the desired manner.
Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.
I claim:
1. An oil burner comprising means pro 'viding an open topped receptacle having front, back and side walls, said receptacle having a bottom with a raised central portion in the form of a square pyramid, a baflle plate extending downwardly and rearwardly from the front wall to a point over the forward side of the square pyramid, means for discharging liquid fuel on the upper side of the baffle plate so as to trickle down over it and fall onto the forward side of the square pyramid, there being provision for admitting air to the receptacle beneath the baffle plate so as to be directed downwardly thereby against the forward side of the pyramid to pick up the vaporized fuel and then sweep rearwardly along the sides of the pyrami 2. An oil burner for boiler furnaces, wood stoves and the like comprising means providing a bottom, front and side walls, there being an air inlet in the front wal1,a baflle extending downwardly and rearwardlyfrom the front wall above the air inlet, means for discharging oil onto the top of said baffle, means providing an upwardly and rearwardly extending surface. on the bottom beneath the baffle, said surface having its sides spaced from said side walls, and means providing side surfaces at the sides of the mentioned surface which converge upwardly and which are spaced from the side walls.
In testimony whereof I have signed my name to this specification.
CHARLES E. 'BEYER.
