WILLIAM J. BEST, OF DETROIT, MICHIGAN.

HYDROCARIBON-BURNER.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application filed November 23, 1908. Serial No. 464,163.

To all whom it may concern:

Be it known that I, IVILLIAM J. BEs'r, a citizen of the United States, and a resident of Detroit, in the county of \Vayne and State of Michigan, have invented a new and Improved Hydrocarbon-Burner, of which the following is a specification.

My invention relates to improvements in evaporating hydrocarbon burners, and its object is to provide simple and effective means to insure the evaporation of the liquid fuel.

My invention consists in combination with a main burner, an evaporator to supply fuel therefor, and a sub-burner to heat the air which passes through the evaporator, of a pilot light so arranged and constructed that the ignition of the sub-burner is insured.

It further consists in the novel arrangement and construction of the sub-burner as shown in the accompanying drawings, in which Figure 1 is a vertical cross section of my improved construction. Fig. 2 is a vertical cross section on the line 22 of Fig. 1. Fig. 3 is a view on a larger scale of the cross section of the sub-burner shown in Fig. 1. Figs. l, 5 and G are views similar to Fig. 3 of various modifications of the construction of the sub burner.

Similar reference characters refer to like parts throughout the several views.

Hydrocarbon vapor burners constructed with a main burner and a sub-burner, an evaporator, a pipe leading from the evaporator to the main burner and the sub-burner, and a pipe for conveying the air heated by the sub-burner to the evaporator, have always been liable to have the sub-burner extinguished. In this present construction the parts are either so arranged and constructed, or a pilot burner has been provided, as to insure the constant ignition of the sub-burner. As the operator always has the main burner plainly in view, it is desirable that this be the source of ignition. It is also desirable, although not necessary, that the sub-burner be near the main burner so as to render the operation of the pilot burner most effective. The greater the dis tance between the burners, the larger will be the amount of fuel consumed by the pilot burner.

In Figs. 1, 2 and 3 the main burner cham her 1 is shown cylindrical although any other desired form can be employed. The

burner 2 is of any suitable foraminous material and of any desired contour, according to the fuel employed and the ideas of the manufacturer, but it is preferably a slotted circular casting. Connecting to the chamber 1, preferably at the lower part thereof, is a suitable tube or pipe 3 which extends upwardly and connects to the evaporator chamher at. 1V ithin this chamber is a gauze or perforated sheet 5 upon which the liquid hydrocarbon falls from the valve 6 that connects to the source of supply. The rate of flow may be watched through a window 7. The air passing through the screen and down the pipe 3 evaporates the fuel on the screen 5 in the usual manner.

The wall of the chamber 1 is perforated or formed with slots 8, around which slotted portion is secured a short tube 9 having side openings 10 and top opening 11. The hydrocar'bon vapors pass out of the chamber 1 into this tube 9 where they burn, the opening 11 permitting their ignition and the openings 10 permitting air to pass to the flame. This tube and the bars 12, of a thin plate of cast iron, form the sub-burner.

A bracket 14, connected to the tube 9, furnishes a support for the lower end of the tube or pipe 15 that extends to the evaporator chamber l and communicates therewith above the screen 5. \Vhenever the vapor is ignited at the openings 8, the products of combustion and hot air will rush up the tube 15 drawing with them a current of air through the opening between the lower side of the tube 9 and the lower end of the pipe 15. It will be noticed that this subburner may be located wherever else desired so long as a supply of air can be drawn up into the pipe 15. In order to ignite this sub-burner a pilot burner may be employed, which may be constructed as follows. A flat casing 16 is attached to the plate 17 of the subburner or to the body 1, if the plate be omitted. This casing receives fuel vapor through a passage 18 from the cylinder 1 which fuel passes out through the long slot 19 and

short slots

20 and 21. A hood 22 secured to the bracket let prevents dust. from falling into these slots and also shelters the flame. \Vhen the fuel vapor is ignited over the main burner 2, the flame will pass to the vapor escaping through the openings 20, then down along the slot 19 to the slots 21 and then through the opening 11, igniting the fuel of the sub-burner. The casing 16 V and burn over the plate 23.

forms a pilot burner which transfers the flame of the main burner to the sub-burner whenever necessary. The channel beneath the hood should be just sufficient to permit the flame to run along the slot 19. The width of all the slots should be less than sufficient to permit the flame to pass through.

In the modified form shown in Fig. a, the main chamber 1, burner 2, and tubes 3 and are as before described. The plate 23 has slots 2st through which vapor may pass When it first escapes, it passes upward through the opening 25 in the tube 26 and is deflected toward the main burner 2, by the hood 27 where it will ignite, and the flame will travel back 7 to the plate 23 and cause a current of air to described constructions.

pass up the tube 15. it will be noticed that this construction has no pilot burner but has a pilot channel.

In Fig. 6 the shape of the pilot channel and the hood 30 ditters from the previous The hood 30 is formed integral with the tube 31, and the flame will travel down the passage 33formed by this hood and the vapor will then burn over the plate 32.

Fig. 5 again shows both a pilot burner and a pilot channel for the same. A ring 34 is secured at the upper end of the chamber and has slots to form the main burner, slots 36 to form the sub-burner, and slots 37 to form the pilot burner. The vapor passing through the slots 37 will ignite from the main burner and the flame will travel through the opening 38 to the sub-burner, and the hot air and 7 products of combustion will pass out of the tube 39 into the pipe 15. The hood 40 again shelters the flame of the pilot burner.
