BURNER FOR VAIOR-STOVES.

Pate t-ed Sept. 6,1921- Application filed February 20, 1919." Serial No; 278,161.

To all whom it may concern.

Be it known that I, HENRY PRICE BALL,

a citizen of the United States, and a resident of borough of Brooklyn, county of Kings, city and State of New York, have invented a certain new and useful Burner'for Vapor- Stoves, of whichthe following is aspecification. 7

My invention relates to burners for vapor stoves or lamps and more particularly to such forms of devices wherein alcohol in solid or liquidforms is employed as the fuel and isconsumed in the receptacle in which it is vended.

The object of my invention is to provide a device which may be employed in conjunction with any open ended fuel holder, such as a can, and which may, by its position relatively to the fuel holder, produce a flame of intense heat and rapid consumption of the fuel contents of the holder, or produce a flame of considerably less heat and a proportional decrease in fuel consumption.

A further object is to provide a device which will be simple in construction, cheap of manufacture, which will not get out of order, simple in operation, and which may beused in-connection with existing solid fuel lamps or stoves. v

These and further objects will more fully appear in the following specification and accompanying drawingsconsidered together or separately.

I have illustrated one embodiment of my invention in the accompanying drawings in which'like parts in all of the several figures are designated by similar reference characters, and in whic 1 Figure l is a plan view of a solid alcohol lamp or stove with my invention associated therewith in the position to give a flame of reduced intensity. 7 v l Fig, '2 is a sideelevation, partly in section of'the same, the section being taken on the line 2 of Fig; 1.

Fig. 3 is a similar view illustrating the invention in reversed position to produce a flame of large size and intense heat.

' "Fig. 4 is a side elevation the burner showing a modification, and

Fig. 5 is a fragmentary plan View of the same;

In the drawings 1 designates a cylindrical tubular member, which. may be termed a chimney. At one end the chimney is pro vided with an exterior, peripheral flange 2. The flange is preferably dished as shown although this is not necessary to the operation of the device. The flange may be se cured to the chimney in any desired manner, or it may be integral therewith.

Extending radially from the flange 2 is an arm 3 which is riveted or otherwise secured to the flange. The outer or free extremity of the arm carries a knob or handle 4 which may be of heat insulating material or of such a construction that it will not readily become heated. Betweenthe flange 2 and the opposite end of the chimney is a series of radially projecting fingers 5. The fingers are preferably three in number, equally spaced apart, and may be formed by cutting U shaped slits in the wall of the chimney and bending the strips produced thereby outward at right angles to the wall of the chimney. The extremities of the fingers are preferably bent slightly, as shown at 6', in the direction away from the flange 2.

Preferably the chimney 1, flange 2, and arm 3 are made of sheet metal but I desire to have it understood that the device may be of cast metal, in which case the openings produced by the bending outward of the fingers 5 will be omitted, or the device may be partly of'sheet material and partly O1 castmaterial, or it may be made in any other desired manner. a a

The deviceof the invention is adapted to be used in connection with a cylindrical, Open-ended receptacle 7 such as is shown "in my Patent No. 1,268,786, of June 14, 1918, but I desire to have it understood that the invention may be employed in connection with any open ended container, and" may with slight and obvious modifications be used with lamps or stoves of other than'cylindrical'shape. a y

F igs. 4 and 5 illustratea modification in which the device is made of cast metal, with the chimney 1 flange 2, fingers 5 and handle arm integral. The flange may be provided with a series of openings 8 for a purpose to be hereinafter described.

When the burner is in the position shown in Figs. 1 and 2 the flange 2 will rest upon the annular insert 9 in the top of the can and its periphery will rest within the top of the can as shown. When the fuel 10 prefera-bly port combustion willbe drawn in through the chimney 1 and the flame rising through the opening will restrict the opening whereby the amount of air for supporting combustion will be reduced.

As the level of the fuel recedes the flame will remain in the upper part of the can because of the small supply of air which will be consumed in the vicinity of the then lower edge of the chimney 1 which is approximately at the level of the top of the can. The heat of the flame will, however, be suflicient to vaporize the alcoholcontent of the fuel even to the last drop.

The flame issuing from the top of the chimney will be small and will give off a relatively small amount of heat. The vaporizing of the alcohol will be slow wherebyeconomy of operation may be attained.

When the burner is reversed to the position shown in Fig. 3, the fingers 5 will rest upon the insert 9, the lower end of the chim ney will extend into the can, and the flange 2 will be at the upper end of the chimney. Air to support combustion will enter the annular space between the chimney and the insert. When the fuel is ignited flame will,

because of the abundance of air admitted through the annular opening, rise to a considerable height above the top of the chimney and will fill the entire cross sectional area thereof.

The heat given oil will be intense and the fuel consumption will consequently be rapid. As the level of the fuel recedes the flame will follow the surface thereof and combustion will take place before the alcohol vapor can rise to any considerable extent. This is made possible by reason of the shape of the chimney and of the annular opening between the same and the insert. The annularopening will act as a nozzle and direct the inrushing air downward into the can. This action is materially assisted by the flange 2 which prevents the air heated by contact with the outside of the chimney.

from rising and the inrushing cold air will, together with the'heated air, be forced downward into the can and support combustion at or near the surface of the fuel until it has all been consumed.

In use let it be assumed that boiling water is desired. The burner is placed in the position shown in Fig. 8, and the fuel lighted. A' vessel containing water is now placed over the burner and a short distance above it. A large, hot flame will be produced which will spread all over the bottom of the boiler, and the water will be quickly brought to the boiling point or other desired temperature. If it is the" intention to keep the water at a eomparativelyhigh temperature but below the maximum, the burner is removed from the can. The large opening port thev tube when the. latter is in the defined by the insert will permit of the entrance of air sufficient to support a flame of considerable size and heat.

If it is desired to keep the'water merely warm, the burner is inverted and placed in the position shown in Fig. 2. The flange 2 will out off the supply of air through the annular opening and the flame will be greatly redueedin size and intensity.

- By the employment of the openings 8 in the flange 2 the. capacity of the device, when used in the position shown in Fig. 2, will be about midway between the maximum, and minimum. 7

In accordance with the provisions of the patent statutes I have deseribedthe principle of my invention, together with the apparatus which I. now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is -merely illustrative, and that the invention may becarried out in other ways.

Having now described my invention what I claim as new and desire to secure by Letters Patent is.
