OIL BURNER.

Application filed March 21, 1925.

This invention relates to new and useful improvements in an oil burner.

()ne object of the invention is to provide a burner of the character described having a novel construction for vaporizing the fuel to be utilized.

Another object is to provide an oil burner of the character described equipped with an air regulator whereby a proper mixture of air and fuel may be, at all times, maintained, to induce the complete combustion of the fuel.

A further feature of the invention is to provide a burner of the character described which may be readily taken apart for clean ing.

A. still further feature of the invention is to produce a burner of the character described which is of simple construction and can be cheaply and easily manufactured, and is economical and eflicient in use.

With the above and other objects in view, this invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illus trated in the accompanying drawings, where in Figure 1 is a vertical sectional view of the burner.

Figure 2 is a perspective view, partly in section, and

Figure 3 is a cross section of the air reglr lator.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the base of the burner. This base is preferably circular in form, and, as shown, has a central upstanding distributer 2, formed integrally therewith, and provided to distribute, or film, the fuel, preparatory to the vaporization thereof.

Around this distributor the base is formed with an annular primer pan 3, having an overflow outlet 4. adapted to be connected with. a suitable overflow line, (not shown).

Fitted over the distributor 2 there is a generator cap 5, provided with an annular hood-like rim 6, forming a flame spreader around its upper end. This cap is provided with an eye 7 to receive an implement for removing itwhen it is desired to cleanse the same.

A fuel inlet duct 8 leads up through the Serial No. 17,374.

distributor and has its upper end cross grooved as at 9, and the fuel flows in through an inlet line, not shown, and passes up through the duct 8 and is distributed through the grooves 9 and flows in a film over the distributer and between it and the cap 5. Vihen the fuel is first admitted, and before the burner becomes hot, the fuel will collect in the primer pan 3 where it may be ignited. The flame will soon heat the generator cap and distributer and the film of oil flowing between them will be converted into vapor which is readily combustible. The flame thereby generated will be: distributed throughout the combustion chamber of the stove, by the flame spreader 6.

In the preferred form of burner, as shown, the distributor is formed with external, annular pockets 10, and the cap 5 is formed with inside, annular beads 11, conforming in shape to, and depending into, but spaced from the walls of the corresponding pockets 10. These pockets will fill with the fuel and overflow, the fuel trickling down over and around the outside of the distributor in a thin film all the way around, and the intermeshing beads, being relatively thin will. soon become very hot thus facilitating the vaporization of the fuel.

The base 1 is provided with a plurality, preferably four, of air inlet openings 12, arranged around the primer pan 3, and designed to permit the upward passage of air to the mixing chamber 13, above said pan. Rotatably mounted on the base, there is an air regulator 14, which is annular in form and of hood like construction, with its outer wall 15 resting on the outer margin of the base and its inner wall 16 resting on the outer margin of the priming pan 3. Between the outer and inner walls of this regulator there are thin partitions 17 which form the regulator with the air openings 18 corresponding in shape and position to the air openings 12 of the base 1, said openings continuing on through the wall 16 into said combustion chamber. When said openings 12 and 18 fully register a maximum amount of air is admitted through them to the flame to support combustion. By turning the regulator the supply of air may be restricted, to obtain the desired mixture, or completely out off.

What we claim is 1. A burner including a base, a distributer thereon, said base having an air inlet opening adjacent the distributer, a generator cap fitted over the distributer and forming a fuel film channel between them, said burner having a fuel inlet duct terminating in said channel, an annular air regulator on the base forming a mixing chamber between it and the cap into which said channel discharges fuel, said regulator having an air inlet opening adapted to be brought into, and out of, registration with the base opening to regulate the flow of air into said chamber.

2. A burner including a base, a distributer thereon, said base having an air inlet adjacent the distributer, a generator cap fitted over the distributer and forming a fuel film channel between them, said burner having a fuel inlet duct terminating in said channel, an annular air regulator on the base forming a mixing chamber between it and the cap into which said channel discharges fuel, said regulator having an air opening adapted to be brought into, and out of, registration with the opening to regulate the flow of air into said chamber, and a primer pan into which the bottom of said chamber is formed.

3. A burner including a base, a distributer thereon, said base having an air inlet adjacent the distributer, a generator cap fitted over the distributer and forming a fuel film channel between them, said burner having a fuel inlet duct terminating in said channel, an annular air regulator on the base forming an annular mixing chamber between it and the cap into Which said channel discharges fuel, said regulator having an air opening adapted to be brought into, and out of, mg istration with the opening to regulate the flow of air into said chamber, and a primer pan into which the bottom of said chamber is formed, said pan being provided with an overflow outlet.

in testimony whereof we have signed our names to this specification.
