DAVID E. PEPPER AND HENRY STRELOW, OF VENICE, CALIFORNIA.

OIL-BURNER.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed J uly 16, 1917. Serial No. 180,809.

To all whom it may concern:

Be it known that we, DAVID E. PEPPER and HENRY S'rRELow, citizens of the United States, and residing at Venice, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

Our invention relates to improvements in oil burners; and the objects of our improvements are, to provide a gas generating box in a furnace having gas outlet openings in the path of the inrushing air; to provide a heating pan below the gas generating box; to provide a gas deflecting baffle or plate on the gas generating box projecting downwardly from the gas generating box into the path of the inrushing gas; to provide a gas deflecting baflie within the heating pan projecting upwardly into the path of the passing gas; to provide gas igniting and starting means connected to the gas heating pan; the invention consisting in the construction, combination and arrangement of devices hereafter more fully described and claimed, and illustrated in the accompanying drawing, in which- Figure 1 is a vertical longitudinal section through our device.

Fig. 2 is a fragmental top view of the heating pan.

Fig. 3 is a front elevation of the fuel connection of our device.

Similar numbers refer throughout the papers.

In Fig. 1, 3 designates the gas heating pan, having an inclined front 4. a base plate 5 and the side plates 6. A deflecting batlle 7 is provided on the base plate crosswise to the heating pan for directing the passing gas upwardly. The baflle is spaced from the side plates 6 so as to allow fuel oil to pass sidewise from the baffle from the front to the rear or in the opposite direction, as indicated at 8. The gas generating box 9 is disposed above the heating pan so as to heat fuel oilinjected into the box for the purpose of generating gas. Gas escaping openings 10 are provided in the front plate 11 of the box. The front plate is extended beyond the to similar parts bottom of the box forming an. atomizing baflie 12 for the purpose of atomizing eventually from the box downwardly dripping fuel oil by the draft passing below the atomizing baffle into the burner. An extension plate 13 is provided above the inclined front plate of the heating pan to direct the inpassing air close past the gas escaping openings 10 in the gas generating box 9.

A fuel oil supply pipe 14 is provided with a fitting 15 allowing a supplying of fuel oil into the heating pan through the valve 16 for starting the furnace.

After the fuel oil is fed into the heating pan and ignited, it naturally heats the gas generating box 9. At this moment, a slight stream of fuel oil is injected into the generating box also, through the operating valve 17, and this fuel oil is generated into gas in the heated box 9.

The generated gas escapes from the box through the openings 10 and is drawn into the heating pan below the generating box by the inpassing air passing the openings 10. as will easily be understoo Having succeeded in generating gas in the heated box 9 to such an amount as to warrant a continuous stream of gas from the generating box, the priming supply is shut off by closing the priming valve 16, and the burner is then in condition to operate on gas only.

Having thus described our invention, we claim:

1. In an oil burner of the class described a heating pan having an inclined front plate, two side plates and a base plate; a deflecting baflle provided on the base plate crosswise to the heating pan; and a gas generating box disposed above the heating pan spaced from said base and the inclined front plate forming a passage for the air draft and having gas escaping openings toward the front in the path of the air passage.

2. In an oil burner of the class described in combination with a heating pan. a gas generating box having inclosing plates in the front, the rear, the two sides, the top and the bottom; the front plate being provided with gas escaping openings so as to compel the generated gas to pass out of the box into the path of the inpassing air in such burner; set our hands at Los Angeles, California, the front plate being also provided with an this 9th day of July. 1917. extension plate projecting downwardly DAVID E. PEPPER. forming a deflecting baflie and atomizing HENRY STRELOW. 5 means between the'heating pan and the gas In presence of generating box. HANS BRINCK,

In testimony whereof we have hereunto OTToH. KRUEGER.
