OIL BURNER;

Application inea July i1, 1923. serial No. 652,139.

T0 all whom t may concern:

Be it known that I, CHARLES A. JAPHET, a citizen of the United States, residing at Seneca, in the county of Nemaha and State of Kansas, have invented Oil Burner, of which the followingis a specification. f

This invention relates to an improvement in oil burners adapted to burn any kind of liquidy hydrocarbon fuel, provision being made for the introduction of water into the fire chamber and its conversion into steam to mix with the vaporized fuel and increase the efficiency thereof when the heavier liquids are used.

The general objects of the invention are i to provide a simple and inexpensive burner structure composed of a minimum number of parts and to provide improved means for introducing and distributing the fuel and water and for .controlling the mixing thereof after the same has become vaporized, whereby complete combustion is effected without formation of soot and a hot White iiame is emitted.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawing which illustrates the preferred form of the invention. p

In the drawing: l

Figure 1 is a vertical section through the burner and the associated parts.

Figure 2 is a horizontal sectional view substantially on the line 9,-2 of Figure 1.

Referring more specifically to the drawing, the invention comprises an air ue 5, frusto-conical in shape, and adapted to rest on a grate 6. The base of the flue is surrounded by a rim of cement 7, or the like, for securing the same in position, and also preventing any draft of air around the outside of the flue. erably made in a single casting, includes a central portion 8, which tapers upwardly to a rounded upper end 9, which lis substantially in the same horizontal plane as the upper rimv of the flue 5 and disposed centrally thereof. An oil supply duct 10 is disposed centrally of the tapered portion 8, and its lower end is connected with a suitable oil supply pipe 11. The burner casting also includes a circular base 12 extending outwardly from the base of the tapered a new and useful The burner, which is prefportion 8, and having concentric channels 13 and 141 on its upper face. Water is sup-` plied to the outer channel 14through a water pipe 15, which terminates in a 'downwardly turned nippleor street L 16 extendf n to heat up, and then the oil becomes vaporized as soon as it leaves the duct 10. The

steam, which is generated from the water in the channel 14, rises up and becomes thoroughly mixed with the vaporized oil within the cap 16, which is 'supported in spaced relation above the tapered portion 8 of the burner and the air iiue 5, by means of legs .17 which extend inwardly from the rim 18 ofthe cap and rest on the upper rim of the conical iue 5. The cap 16 may be provided with a ring or handle 19 for removing the same to light the burner. The rim 18 of the cap is provided with a series of openings 20, through which the flames are emitted. The legs 17 support the cap above the air flue and burner so as to' form a chamber in which the vaporized oil and steam become thoroughly commingled with the air admitted through the flue 5, so that a complete combustion is effected.

` The water supply pipe 15 does not come in contact with the hot part of the burner, and consequently there is little tendency to form lime deposits within the pipe. If these are formed, however, the pipe may be easily removed and cleaned.

From the foregoing description, it will be seen that the invention is very simple in its construction, and may be easily installed in any stove or furnace at a very moderate cost. The cap 16 forms a chamber where the oil., steam and air become thoroughly mixed, thus resulting in a complete combustion and a hot white dame, which is discharged through the openings 20.

While I have shown and described the specific construction of one form in which the-invention may be embodied, it will be understood that various modifications may be made yin theysize, proportion and arrangement of the various parts to adapt the same to the special conditions under which lll the saine may be installed, and it is my intention to include all such modifications Within the scope of the appended claims.

What is claimed is:

l. In an oil burning device, the combination of an upwardly tapering air flue, a burner member having an upwardly tapered central portion With an oil supply duct discharging at the upper end thereof, an annular extension at the base of the burner member having concentric channels in its upper surface, the inner channel being at the base of the central tapered por# tion for receiving the oil discharged from the duct, a Water supply pipe leading to the outer channel, and a cap supported above the air iiue and spaced therefrom, said cap beingv provided near itsbase With a series of openings for the emission of the flames and the products of combustion.

f 2. In an oil burning device, the combination of a frusto-conical air flue, a burner member having an upwardly tapered central portion with an oil duct discharging at the upper end thereof, the mouth of said duct and the upper edges of the air flue being' in the saine horizontal plane, an annular extension at the base of the burner memlberhaving concentric channels in its upper surface, the inner channel being at the base of the central tapered portion for receiving the oil discharged from the duct, and a cap having lugs engaging the upper edge of they nature.
