OIL-BURNER.

Specification of Letters Patent;

Patented Jan. 5, 1915.

To all whom it may concern uBe it known that I, VVALLACE VVrLson, residing at Seattle, in the county of King and State of Washington, have invented a certain new and useful Improvement in Oil-Burners, of

Wh'ich-the'followin'g 1s a specification.

-My invention relates. to improvements in oiL-burners that are adapted to be placed Within the fire box of an ordinary cooking or-heating stove and that are further adaptedito burn liquid fuel, as crude oil, kerosene,

E gasolene, and the like, and the object of my improvement is to :provide a simple and efficient burner that may be connected W1th a pressure tank that may contain certain liquid-fueland water which may be conducted: to such'burner to be burned in the formiof -gases. I accomplish this Ob]6Cl3 by devices .illustrated in the accompanymg drawings in which- Figure 1 is a view in frontelevatlon of a r: burnerembodying my inventibn as it appears when disposed within the fire box of a stove and associated with a fuel tank ready for use, Fig. 2 is an enlarged view partly in vertical section and partlyifnside elevation of a burner body embodied in my invention, Fig. 3 is a view in vertical section of a fuel tank that is embodied in my invention, and Fig. tie a view in vertical section of a detail of my invention; f

Like reference numerals indicate like parts throughout the drawings Referring to the drawings, 6 is an ordinary kitchen stove, 7 is an oil burner d1sposed upon the grate withinthe fire box of said stove 6. A fuel supply tank 8 is disposed near said stove 6 and divided into two separate compartments. A fuel supply pipe 9 leads from the tank 8 to the burner 7 for conducting fluid fuel to the point of combustion and a water supply pipe 10 forms a connection between the tank 8 and the burner '7 through Which water may be conducted to the burner 7 there to be converted into steam to aid combustion.

Referring to Fig; 2 of the drawing, 11 is a concavo-convex saucer shaped member that forms the base of an oil burner, 12, 12 are legs upon which the base 11 is, suported, 13 is a boss disposed concentrically on the lower convex'surface of the base 11, such boss beposed approximately in the center of the base 11,

legs 1? face of the base 11 within the space inclosed by the ridge 15 which ridge 15 serves to keep the deflector 16 always in the center of-the base 11 and to form a receptacle for Water that may flow out of the pipe 10. A perforated flange 18 is provided on the edge of the base 11 and a pipe 19 that is connected with the fuel supply pipe 9leads upwardly through the perforation in such flange 18 and is formed into a helical coil 20 that is disposed concentrically with the base 11, a short distance above such base, such coil terminating in a U shaped loop 21. which presents a downwardly projecting end 22 above the center of the helical coil 20, said end 22 being adapted to be closed by a cap 23 which is formed like a butterfly nut that it may be more easily removed, which cap 23 is provided with perforations 24c, 24 where by fuelmay be emitted downwardly therefrom through the helical coil 20. The top and bottom end portion of the helix 20 comprising the loop 21 and the lower end of the pipe 19 are each filled with wire gauze 25- with its convex side uppermost, the belng adapted to rest upon the sur- The fuel tank 8 is formed with an upper i water compartment 26 and a lower oil compartment 27. An inlet pipe 28 is provided in the water compartment 26 and a similar inlet pipe 29 is provided in the fuel compartment 27 whereby Water and fuel may be introduced into these respective compartnlentsg

such inlet pipes

28 and 29 each being provided with

suitable caps

30 and 31 by means or which their top ends may be tightly closed.

32 is an outlet pipe connecting the water supply pipe 10 with the water compartment 26, such pipe '32 being provided with a valve I outlet pipe that connects the fuel supply pipe 9 with the fuel compartment 27, such fuel outlet pipe 34 being provided with a valve 35 by means of which the supply of fuel delivered through such pipe may be regulated or may be entirely shut ofl.

An air pump 36 of any suitable form is provided in the top of the fuel tank 8, and

is adapted to extend downwardly into the water compartment 26, said pump 36 being provided on its lower end with a valve that acts to permit air to be expelled from the lower end of the pump but acts to prevent air or water from being drawn in at the bottom end of such pump, said valve consisting in a reducing member 37 that is provided inthe lower end of the pump cylinder which reducing member 37 is adapted to be closed by a valve disk 38 having a plate 39 of rubber or like material on its top side that is held in contact with the lower end of the reducing member 37 by a helical tension spring 40 as illustrated in Fig. 4. 1

A pressure gage 41 is provided on the top end of a pipe 42 which extends downwardly through the top ,of the fuel tank 8 and through the water compartment 26 and communicates with the oil compartment 27, a small hole 43 beingprovided in the pipe 42 at a point near the top of the water chamber 26 whereby pressure within the two

chambers

26 and 27 may be equalized.

In the operation of a burner containing my invention as shown and described the device is set up, as illustrated in Fig. 1, with the body of the burner disposed within the fire box of an ordinary stove and the fuel tank Slocated at any convenient point adjacent thereto. The fuel supply 'pipe 9 is provided-to communicate between the fuel compartment 27 of the tank Sand the burner coil 20 and the water supply pipe 10 is provided to communicate between the water compartment 26'of the tank 8 and the base portion 11 of the burner. 'W'hen the burner is to be lighted the pressure within the tank is raised to any desired amount by operating the pump 36. The valve 35 is then opened slightly to admit fuel to flow through the pipe 9 into the coil 20 through which coil it rises into the loop 21 and is emitted downwardly through the perforations 24 on to the convex top surface of the deflector 1(3, and thence it flows oil of such deflector 16, into the bottom of the saucer shaped base 11. When enough fuel has collected within the base 11 to heat the coil 20 sufliciently to vaporize the fuel contained therein the'valve may be closed and the fuel within the base 11 is ignited to burn to vaporize the fuel within the coil 20 and to heat the base 11 and the deflector plate l6-to a high temperature, thus causing vapor instead of liquid fuel to be emitted from the perforations 24 to burn within the coil .20 and to be deflected outwardly by the deflector 16 to burn above the base 11.

As soon as the burner is sufiiciently heated the valve 35 may be opened again to a desired degree to regulate the flow of fuel at a rate properly to feed combustion andthe valve 33 may be opened slightly to permit a small amount of water to flow through the pipe 10 and upwardly through the perforation 14 to spread out over the bottom of that portion of the heated base llthat much hotter flame than could'be obtained I with the vaporized fuel only.

Obviously changes in the details of construction and form of various parts of my device may be resorted to without departing from the spirit of my invention or sacrificing any of its advantages.

What I claim. is:

1. In a burner of the class described, the combination with a saucer shaped base portion, of a c irved deflector disposed above the central part of said base portion, a helix of pipedisposed above said base portion, said helix of pipe being connected with a. suitable source of fuel supply and adapted 1 to emit fuel downwardly on to said curved 2. In a burner of the class described, the

combination with a saucer shaped base portion, of an annular ridge concentrically dis posed on the upper surface of said base portion, a curved deflector disposed above thevcentral' part of said base portion, a. water supply pipe communicating with'said base portion to deliver water within the space inclosedibygsaid annular ridge, a helix of ipe disposed above said base portion the lower end of said pipe being connected with a source of fuel supply and its upper end portion dieing formed to project downwardly above said helix and provided with a perforated cap through which fuel may be emitted downwardly, and a pressure. tank for fuel and water.

3.,In a burner of the class described, the combination with a base portion that may form a receptacle for liquid, of a'helix of pipe disposed above said base portion and connected with a source of fuel supply, aw-
