LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed January 31, 1910. Serial No. 541,131.

To all whom it may concern:

Be it known that I, BENTON MOORE, a citizen of the United States, residing at Cherryvale, in the county of Montgomery and State of vKansas, have invented a new and useful Liquid-Fuel Burner, of which the following is a specification.

The burner which is the subject of the present invention is designed more particularly for use in connection with ordinary cooking and heating stoves, and it has for its object to provide an improved burner in which a mixture of Oil, air and steam is sprayed into a pan located in the fire box of the stove.

Another object of the invention is to provide a burner of the kind stated which is simple in structure, and highly efficient in operation, and also one embodying certain novel structural details to be hereinafter described and claimed.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a central vertical section, and Fig. 2 a plan view of one form of burner, and Fig. 3 is a vertical section, and Fig. 4 is a plan view of another form.

In Figs. 1 and 2 is shown a burner designed for use in connection with a cooking stove. Vithin the fire box of such a stove, and preferably supported on the grate thereof, is an open pan or tray 5 into which the combustible mixture is discharged. The fire box of the stove is entered by an air supply pipe 6 opening at one end through the door of the stove. The opposite end of the air pipe is enlarged and directed downwardly into the pan, as indicated at 7, so as to discharge into the center of the pan. The discharge end of the air pipe is spaced a short distance above the bottom of the pan by legs 8. Located centrally within the down turned end 7 of the air pipe, is a cylindrical tube 9 which is closed at its upper end, and open at its lower end, said lower end being spaced 2. short distance from the discharge end of the air pipe.

Above the pan 5, and partly surrounding the down turned end 7 of the air pipe, is a steam generator 10 in the form of a pipe entering the fire box of the stove through the door thereof. On the outside of the stove the steam generator is entered by a water supply pipe 11 of smaller diameter than the diameter of the pipe forming said generator. The inner end of the generator terminates in an upward bend 12 from which a reduced portion 13 passes into the down turned portion 7 of the air pipe, and enters the upper end of the tube 9.

Entering the outer end of the air pipe 6, and extending lengthwise and centrally thereln, is an oil supply pipe 14, which is extended inwardly as far as the down turned end 7 of the air pipe, and has connected to its inner end, by means of an elbow 15, a downwardly directed discharge nozzle 16 entering the tube 9 through the top thereof, and extending lengthwise and centrally through said tube, the lower end of the nozzle terminating a short distance above the lower edge of said tube. The oil pipe is supported within the air pipe by means of a hook-shaped bolt 17 carried by the air pipe. The tube 9 is spaced from the interior of the down turned end 7 of the air pipe, and the discharge nozzle 16 of the oil pipe is spaced from the interior of the tube. The water and oil pipes are provided with suitable valves 18 for controlling the flow therethrough.

In operation, water is turned into the generator 10, and a small quantity of oil is run into the pan 5, and ignited. The flames from the burning oil play around the generator 10, and when the latter has been heated to a suflicient degree, steam is generated therein, the steam passmg into the tube 9. The steam is discharged down the tube 9 in the direction of the pan 5, and upon meeting the oil issuing from the discharge end of the nozzle 16 is mixed with the same and sprays it into the pan. It will be noted that the tube 9 and the nozzle 16 are spaced from the discharge end of the down turned portion 7 of the air pipe, so that the air passing through the said pipe commingles with the mixture of steam and air, and the resultant combustible product is discharged into the pan in which it burns with an intense heat, and without smoke, perfect combustion being effected by mixing the oil with the steam and air as described.

Figs. 3 and 4 illustrate a slightly modified form of burner, designed for heating stoves. In this form of burner pan 5 is also supported in the fire box of the stove, preferably on the grate thereof. An air pipe 19 extends from the top of the stove in the direction of the pan, a suitable opening being made in the top of the stove in which the pipe is mounted. In the lower end of this air pipe is'located atube 20 similar to the tube 9, and entered by a steam pipe 21 connected to a steam generator 22 located above the pan 5 The oil pipe 23 is mounted lengthwise in the air pipe, and extends into the tube 20. The pan 5 is circular in contour to conform to the contour of the fire box of the stove, and the generator 22 extends in a semi-circle above the pan. Above the pan 5 is located a lid 24 which is supported on said pan by legs 25. The lid is spaced a short distance above the pan, and the generator 22 is located under the lid, there being an opening 26 in the latter through which the steam pipe 21 passes to the tube 20. The lid also has an opening 27 through which the air pipe 19 extends to the pan. The lid 24 acts as a deflector to throw the flames t0 the sides of the stove; otherwise, the operation of the burner is the same as the'one first described.

I What is claimed is:

l. A liquid fuel burner comprising a pan, an air pipe discharging thereinto, an oil pipe in the air pipe, and discharging in the direction of the pan, atube surrounding the discharge end of the oil pipe, and a steam generator located above the pan, and connected to the tube. V

2. A liquid fuel burner comprising a pan, an air pipe discharging into the pan, an oil pipe in the air pipe, and discharging in the direction of the pan, a tube surrounding the dlscharge end of the oil pipe, said tube and discharge end of the oil pipe being spaced from the outer end of the air pipe, and a steam generator located above the pan, and connected to the tube.

3. A liquid fuel burner comprising a pan, a lid above the same and spaced therefrom, an air pipe passing through the lid, and dis charging into the pan, an oil pipe in the air pipe, and discharging in the. direction of the pan, a tube surrounding the discharge end of the oil pipe, a steam generator located above the pan beneath the lid, and a connection between the steam generator and the aforesaid tube.

4. In a liquid fuel burner, an air supply pipe, an oil tube in the air pipe, and having its discharge end spaced from the discharge end of said pipe, a tube surrounding the discharge end of the oil pipe, a steam generator, and a connection between the steam generator and the tube.

In testimony that I claim the foregoing as my own,I have hereto afiixed my signature in the presence of two witnesses.
