ADO'LPH Gr. KAUFIVIAN, OF'NEW YORK, N. Y.

BURNER..

Application filed December 12, 1919. Serial No. 344,336.

To all whom it may concern:

Be it known that I, ADoLrH G. KAUFMAN, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Burner, of which the following is a speeication. p

This invention relates to burners, and especially those adapted to vaporize and burn a hydrocarbon liquid for cookingpurposes; and the object of the invention is to provide a device of this kind which will effectively vaporize a hydrocarbon fluid by utilizing the heat of the flame for that purpose in a man` ner that will convey the maximum amount of heat to the vaporizing part; a further object being to provide a device which will burn high and low grade fuel without change of orice.

The invention is illustrated in the accompanying drawing, in which- Fig. 1, is a plan view of a burner constructed in accordance with my invention;

Fig. 2, is a central vertical section of the same-a part being in full lines; and

Big. 3, is a sectional elevation of a modified form of construction.

In the drawing, like numerals of reference refer to the same parts in each of the views.

In practice I provide a burner l, which may be connected with a fount 5 of any desired construction. Connected with the fount is a vaporizer 6, a part of which is embraced with a collar 7 of a casingS, which is made flaring to embrace the burner proper, above which the casing 8 extends, as clearly shown, in Figure 2, and for reasons hereinafter explained.

The burner proper consists of a plate 10, having a central opening 11 through which the gas may pass after being generated in the vaporizer.

Above the orifice 11 is a plate 12, preferably supported on projections 13 that it may be held a prescribed distance above, and independently of the radial projections .14 on the plate 10.

I may also use a preheating cup 15, and a tube 16 leading from the preheating cup to the top of the burner to make the lighting of the stove easier, if desired.

The operation is as follows: Any desired passes through` the orifice 11, central of this plate. It is then directed outwardly by the plate 12 to the edge thereof where it burns. As the gas is under considerable pressure owing to the common method of forcing the hydrocarbon into and through the vaporizer with compressed air, it will be directed outwardly in burning, as will be understood, by reason of the fact that the plate 12 has directed the flow outwardly. In the flow out wardly it will be divided by the projections 14, which are in the Zone of the flame, and are made of a size, as shown in the drawing, to come in close contact with the rim of the casing 8. The flame is thus directed against the casing 8, and the ribs 14 also become hot, and convey heat outwardly to this casing, from whence it is conveyed downwardly to the vaporizer 6, as will be understood.

It will thus be seen that I have provided special means for heating the conveyor of the heat of the flame to the vaporizer. It will be understood that the more intensely this conveyor is heated the more certainly will the hydrocarbon fluid be vaporized.

In Fig.. 3 I have shown a slightly modified form of construction in that I may provide a perforated casing 17 to convey the vapor from the generator 6 to the plate 10'; and

by making the plate 12 with vprojections 13,`

and with projections 18 on the opposite side of the plate so the plate 12 is reversible. The casing 8, and collar 7 are practically the same as in the preferred form.

By making the plate l2 reversible, the stove can be made to burn gasoline, kerosene, or any hydrocarbon fluid that will vaporize and burn in a stove of this kind, giving a wide range.

I claim:

In a stove adapted to generate and burn gas, a deflector plate provided with projections on each side thereof, each set of projections being adapted to support lsaid plate whereby the plate is made reversible, for the purpose set forth.

Dated December 11th, 1919.
