OIL BURNER.

Application filed May 15, 1923. Serial No. 639,055.

To all whom it may concern:

Be it known that we, W'ILLIAM ROCKEFEL-;

C pings with the fuel supply tank.

Another object is to provide an oil burning stove having a burner nozzle and a fuel supply tank, the fuel oil being delivered to the burner thru a feed pipe by a pressure pump.

Still another object is to provide an igniting pan beneath. the burner nozzle, and means for removing said pan from beneath the nozzle when the surface of the oil there in is to be fired. These and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a sectional elevational view taken substantially centrally thru the entire stove.

Figure 2 is a front elevational view showing the external construction.

Figure 3 is a bottom plan view of Figure 1.

Figure 4 is a cross sectional View taken on line 44 of Figure 2, and illustrates the means by which the igniting pan is removed.

Referring indetail to the drawing, the numeral indicates an annular apron which provides a lower casing. Said casing has an opening therein which is normally covered by a hinged door 11. A conical hood 12 in which a plurality of vent holes 13 is provided, has a flange 14 thereon riveted to the upper edge of the apron 10. A cylindrical member 15 forms a hood and is provided with a relatively large opening covered by a hinged door 16, the latter hav- 1 ing a latch 17 thereon to retain said door in closed position. Said hood is seated upon the upper edge of a conical sleeve 18. The lower portion of the conical sleeve is formed into a cylindrical sleeve 19 at the lower edge of which an annular bed plate 20 is seated. Between this plate and a similar one 21 above it, a quantity of asbestos 22 is stored in order to separate the hood chamber 23 from thefapron chamber 24.

A ring strap 25 is secured to the interior wall of the apron at its lower end, and is connected to a smaller ring 26 by a plurality of legs 27 said rings forming a supporting frame for a tank 28 in which the fuel supply 29 is stored. The front of the tank facing the door opening, is provided with a level glass 30 attached to the tank at the bottom and top in the usual manner. One end ofa filler pipe 31 which is provided with a shut-off valve 32, is connected to the lower portion of the tank, the opposite end passing upwardly within the apron l0 and projecting thru the conical head 12, and being surmounted by a cap 33 which may be removed to fill the tank. A second pipe, also communicating with the tank, projects thru the head 12 and is connected thru a suitable hose or the like, to an exhaust pressure pump (not shown). 35 is connected to the lower end of the tank, and extends vertically upward, having its upper end formed into a U-shaped fixture, the lower arm 36 being provided with the usual relatively small outlet port 37 thru which the fuel oil passes. A diffusing disc 38 is supported by the remaining arm of the U-shaped fixture above the jet.

The upper door 16 has a platform mounted thereon upon which a pan 39 is supported.

In using the stove, a pump is required, which induces a pressure above the liquid 29 in the tank 28. As aforementioned, the pump is preferably connected to pipe 34. The pressure on the fuel oil will cause the latter to pass upward thru the feed pipe 35 to the U-shaped nozzle fixture. Before ignition of the oil, a quantity of oil is allowed to drip into the pan. As the pan is carried upon the platform 40 of the door 16, it is in an accessible position when said door 16 is opened. In order to start the stove burning, the pipe arm 36 is first heated by igniting the oil in the pan. The oil, in passing thru the port 37 of the heated pipe arm 36, will be pre-heated, and hence readily vaporized and ignited by the. flames in the pan. When all the oil in the pan has been consumed, the atomized oil passing from the jet will be The lower end of a feed pipe ignited of itself, and the flames in passing therefrom Will be difiused over the entire chamber 23 by the disc 38.

Vi e claim A heater comprising a body having an upper and lower compartment, thecompartments being separated by an asbestos layer, said compartments having openings therein, hinged doors adapted to cover said openings, as fuel tank in the lower compartment,

' a feed pipe extending vertically from the tankto the upper compartment, the upper end of said feed pipe being formed into a U-shaped fixture, said fixture having a port 7 15 therein, a diffusing disc mounted above said port adapted to spread the flames of the burning oil, an igniting pan belovvsaid port adapted to receive the oilfrom said port before ignition, the burning oil in said pan being adapted to" heat saidffeed pipe, as-plat form beneath said port rigidly securedto the door, said platform adapted to "be rotated with the door and shift the pan therewith,

the" platform having a curved edge generated by using the door pivot as a center.
