Patented Sept. 11, 1934 Application February 1,

1932, Serial No. 590,273

1 Claim. (Cl. 15856) This invention relates to an improved oil burner particularly adaptable for use in domestic cooking stoves and susceptible of efficient operation through the use of fuel oil, kerosene, crude .5 .oil, or such low grade products as used crank case oil.

The object of the invention is to provide a simple and economical burner head and piping arrangement capable of developing the requisite 10.jdegree of heat and desirable because of its unique ability to fulfill the requirements of a structure of this class in an efficient and otherwise satisfactory manner.

The structural details and their relative ar- .irangement and association will become more readily apparent from the following description and drawings.

In the drawings:

Figure 1 is a plan view of the improved oil jburner.

Figure 2 is a side or edge elevation of the structure shown in Figure 1.

Figure 3 is a top plan View of the burner head.

Figure 4 is a central vertical section on the line 4-4 of Figure 3.

Figure 5 is a bottom plan view of the burner head.

Figure 6 is a horizontal section on the line {6-6 of Figure 4, showing the addition of supplemental flame ports.

The burner head is generally denoted by the numeral 12 and comprises a hollow bell-shaped casting 13 whose reduced truncated end is in- Jternally screw-threaded to accommodate the threads of a nut 14 forming a union or connection for the elbow-coupling 15. The fuel supply line 16 is connected to this elbow 15.

The base of the casting 13 is formed with a reinforced marginal rim 1'7 and is internally screw-threaded to accommodate a cleaning plug 18 having a suitable tool grip 19. The shell or casting 13 is also formed with one or more flame .discharge ports or orifices 20 located at suitable points within the vicinity of the plug 18.

The numeral 21 designates a screw-threaded hole into which a water supply line is tapped. The water supply line is generally denoted by the numeral 17. A feature of the part 17 is that it is made up of a suitable number of pipe sections coupled together by appropriate unions and it is formed with a vaporizing coil generally denoted bythe numeral 23. The coil comprises :a lower. convolution 24 whose discharge end is UNITED *sTArEs' PATENT "OFFICE attached by a suitable coupling 25 to the casting 13 through the hole 21.

The coil also includes a larger upper convolution 26, these convolutions being graduated to provide the desired progressive entry of the steam or vap or into the burner head. Of

course, when the water enters the burner head it is virtually converted into a vapor. reason the coil surrounds the burner head for preheating and vaporization of the water.

The inclined portions of the water supply and fuel lines are provided with any suitable type of cut-off and regulating valves.

For this Particular attention is called to the portion 31 of the fuel supply line which is disposed in an approximately horizontal plane and merges with the inclined portion of the fuel supply line.

This

arrangement makes it possible for an even flow of oil thereby eliminating the possibility of an over-supply of oil such as might be possible if this arrangement were not provided.

Evidently there is a certain back pressure produced at this particular point of connection of the oil supply pipe with the burner head caused from excessive heat from the burner.

When the burner cools suddenly however, superfluous oil enters. illustrated in the drawings.

This is eliminated by the arrangement minimizes carbon deposits.

'It is manifest that the parts utilized in the complete structure have been especially selected to provide unification and appropriate co-ordination in function and purpose, and the particular arrangement of piping forming the vaporizing coil and top intake of fuel adds to the unique assemb1y,;with the result that efficient performance is practically assured.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combina-' tion and arrangement of the several parts provided that such changes fall within th the appended claim.

I claim:

e scope of and extending horizontally therefrom for a portion of its length and then being inclined upwardly, and a multiple convolution preheating coil surrounding said casing and having its lower free end connected to said casing, the upper portion of said coil being adapted to be connected to a source of water supply and being inclined upwardly.
