GAS GENERATOR AND BURNER.

Application filed June 1'7, 1918.

To aZZ whom it may concern:

Be it known that I, Eowano ll). ElMALL, a

citizen of the United mates, and a resident of Portland, in the county of Multnomah and State of @regon, have made certain new and useful improvements in Genera tors and Burners, of which the following is a specification.

This invention relates to an improvement in gas generators burners, and one of the principal objects thereof is to provide an improved gas generator and burnerespecially adapted for use in ranges, heating stoves, furnaces and the like.

Another object of the invention is to pro vide an improved generator and burner adapted to use coal oil as a fuel, the construction being such that the oil is volatilized in a chamber forming part of the burner and is fed in the form of gas from a hollow linger communicating with the chant her, the means for vaporizing and feeding the being contained in the burner.

Another object of the invention is to pro vide an improved generator and burner which will be extremely simple, durable, efficient in operation and inexpensive to manufacture. With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction, combinations and arrange ment of parts hereinafter more fully described and claimed and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several figures of which,

Figure 1 represents a vertical sectional view taken through the burner and generator constructed in accordance with my invention.

Fig. 2 represents a side elevational view thereof.

Fig. 3 represents a horizontal sectional view taken on the plane indicated by the line 33 of Fig. 1.

Fig. at represents a plan view of the plate used for spreading the flame. I

Fig. 5 represents a transverse sectional view taken through the plate.

Referring more particularly to the drawing, 1 indicates an annular pan into which a small amount of oil is fed in order to start the burner. This oil is drawn from a reservoir or tank, not shown, through a pipe, not shown, and enters through an opening 10 provided in the bottom of the pan. The

Specification of Letters Patent.

Patented Feb. 3, 1920.

Serial No. 304,756.

pan is arranged below the burner which consists of a lower annular gas chamber 9, and an upper annular gas chamber 8 connected on the side of the burner through a passage 11 arranged at one side of the body of the burner, such passage being of relatively large cross sectional area in order to allow for circulation of gas from the lower to the upper chambers.

The burner has a central air passage 12 eX-- tending therethrough, this passage being enlarged as at 13 in the body of the burner between the upper and lower gas chambers, and arranged in the enlarged portion 13 and restin on the lower wall thereof is a flame spreader or plate 4; provided with a central rib 14. This plate is used for the purpose of spreading the flame in the body of the burner.

Connecting with the upper gas chamber 8, at a point diametrically opposed to the passage 11, is a hollow finger 15 which curves upwardly and over toward the center of the burner, said finger being provided with a restricted port 7 arranged approximately in alinement with the passage 12 through the burner.

Oil for the burner may be fed through a pipe to the inlet tube 2 communicating with the lower gas chamber 9 and which projects down through the pan 1. From the forego ing description taken in connection with the drawing, the operation of the burner will be readily understood. Oil may be fed to the lower gas chamber through the tube 2. Upon starting the burner a small quantity of oil is drawn into the pan 1 and ignited. The flames from this oil will impinge against the body of the burner, thus raising its temperature sufiiciently to volatilize the oil as it is fed into the lower gas chamber.

The gas thus generated finds its way up through the passage 11, into the upper chamber 8 and from there through the finger 15 to the port 7, from which it is directed down wardly through the upper end of the air passage 6 against the flame spreader or plate 4t. The flames from the pan 1, before the pan has burned out will ignite the gas as the latter is ejected from the port 7. The flame directed into the body of the burner will serve to maintain the temperature of the gas chambers sufliciently high to continue the volatilization of the oil as it is fed to the burner.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts thereof, as do not depart from the spirit of the invention and of the scope of the m pended claim.

I; claim:

A gas generator and burner comprising a body formed to provide spaced upper and lower annular chambers and having formed in ones ide a: passagecommunicating With said chamb'ers, said body being provided centrally with a relatively lar e chamber in non-commun catlng relation to said first named chambers and, being further provlded with openings communicating with said cen tral chamber and leading through the top and bottom of the body, a pipe member rising from said body at its side opposite said passage and communicating with the upper of said first named chambers, said pipe being curved to extend over the center of said openings and being provided with a perforation in alinement with the longi tudinal axis of said openings, a plate disposed within said central chamber, and a priming pan beneath said body, the lowermost of said first named chambers being adapted for connection with a fuel supply.
