CRUDE-OIL BURNER,

SPECIFICATION forming part of Letters Patent No. 714,467. a d November Appliuation filed November 21, 1901. Serial No. 83,140. (No model.)

To all whom it may con/001%.-

Be it knownthat I, MILTON A. FESLER, a

citizen of the United States,-residing at Visalia, in the county of Tulare and State of California, have invented certain new and useful Improvements in Crude-Oil Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to the burning of crude petroleum and distillates in cooking and heat- I ing stoves and all kinds of furnaces that are notoperatedin connection withasteam-boiler, and has for its object economy in the use of fuel and labor, the prevention of accidents by fire from the use of crude petroleum and distillates as fuel, freedom from ofiensive odors,

and the cleanliness of the place Where fuel is used. I attain these objects by the mechanism illustrated in the accompanying drawings,

Figure l is a perspective view showing the Fig.

vaporizing-jet and oil and steam supplying connections between the steam-generator, oi1- regulator, and fuel-pan. Fig. 3 is an enlarged detail sectional view of the oil-regulator.

Similar numerals refer to similar parts throughout the several views.

The entire apparatus is constructed of metal.

1 is the fire-box of a stove or furnace.

2 is a steam-cylinder placed in thefire-box and connected with awater-supply from a proper elevation through a pipe 3, having a controlling-cock 4 and connected with the vaporizing-jet by the pipe 5.

6 is the nozzle through which the steam from the cylinder 2discharges into the firebox 1, and 7 .isa rotary valve having a discharge-opening 8 and controlling the escape of steam through the nozzle.

9 is the oil-passage connecting the oil-supply pipe 10 with the discharge-opening 8. j

11 is a starting cup or. pan located in'the fire-box under the steam-cylinder 2 to hold the oil which is ignited for the purpose of heating the steam-cylinder to make steam to vaporize the oil and start combustion of the vaporized oil from the vaporizing-jet 8.

' 15 is an air-tight float moving in the casing 13 and connected with the valve 16 by the stem 17. The float is raised by the oil rising in the casing and closes the valve 16 and stops the oil-supply through the pipe 14, thus antomatically regulating the quantity of oil supplied through the pipe 10 to the vaporizingjet.

18 is an ordinary three-way needle-valve casing placed in the pipe 10 and through which oil is supplied to the pan 11 by means of a handle 19, needle-valve 20, and passage 21 and through which oil is also supplied to the vaporizing-jet. I

The oil-regulator is placed at an elevation which holds the inclosed oil at a higher elevation than the needle-valve 18 and at a lower elevation than the passage 9. This permits the oil to flow through the valve 18 by its own gravity into the pan 11, butprevents its flowing by its own gravity through the passage 9, it being carried through saidpassage into the valve 7 by means of the suction created by the steam escaping from the nozzle 6. By this arrangement leakage of oil through the passage 9 and valve 7 is impossible when there is no steam passing through the opening in the nozzle 6, for the flow of oil is shut ofi in the event of the water-supply being shut ofi from the cylinder 2 or in theevent of combustion ceasing in the fire-box 1.

The valve 7 has a screw-threaded connection with the nozzle 6 and is formed with a gear 22. With this gear meshes a pinion 23, carried by a revoluble stem 24: having a handwheel 25. By turning the stem through the medium of the hand-Wheel the valve 7 will be adjusted to regulate the size of the outlet 8, whereby the feed of oil through the nozzle may be controlled as desired.

The nozzle 6 is part of a burner-valve casing or union 26, having branches 27 and 28 coupled, respectively, with the pipes 5 and 10. The branch 27 has a passage 29 communicating with the nozzle, and the branch 28 a passage 30, communicating withthe passage 9.

The steam passing from the cylinder 2 through the pipe 5, passage 29, and nozzle tends to create a vacuum in the outlet 8, and thus creates a suction, which draws the oil through passages 30 and 9 and unites it with the steam at the outlet 8 and immediately converts the oil into vapor, which is forced into the fire-box 1 and there burned.

The needle 31 is placed in the steam-passage in the nozzle 6 for the purpose of cleaning said steam-passage, which is accomplished by the sliding of the said needle in and out, the escape of the steam being prevented by the packing-box 32 on the casing 26, through which the needle passes.

The scale of Fig. 2 is double that of Fig. 3.

This vaporizing appliance is placed in operation by opening the valve 20 and letting the oil flow into the pan 11, closing the said valve when sufficient oil is in the pan to make steam in the cylinder 2, the oil in the pan 11 being then ignited. The cock t is then opened after the cylinder 2 has become sufficiently hot to generate steam. When the steam discharges through the outlet 8, it assimilates with the oil, as indicated, and is ignited by the flame from the pan 11, after which the flame from the vaporizing-jet will be contin u ous and automatic as long as water and oil are supplied.

I claim- In a crude-oilburner the combination with a heater having a fire box of a starting-pan located within said box, a steam-generator located above the pan, a water-supply pipe extending through one side of the wall of the heater and connected to the generator, a steam-discharge pipe also extending through the wall of the heater and leading from said generator, an oil-regulator arranged for the flow of oil therefrom to the starting-pan by gravity, a nozzle communicating with the interior of the fire-box and connected with the oil-regulator and steam-pipe and located above the level of the oil in said regulator, the flow of oil from the regulator to the nozzle being produced by the suction created by the steam discharging from the nozzle, said generator being located within the heating zones of the pan and nozzle, and suitable valve mechanism for controlling the flow of oil and steam, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MILTON A. FESLER.
