Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed. April 16, 1917. Serial No. 162,383.

To all whom it may concern:

Be it known that'I, Hnnscrrnn E. Conner, a citizen of the United States, residing at Baker, in the county of Baker and State of Oregon, have invented a new and useful Burner, of which the following is a specification.

The subject of this invention is a burner intended for use with fluid fuels.

The main object of the invention is to produce a burner which may be used as a separate heating unit or placed in any ordinary fire box without necessitating structural changes in such fire box.

Another object is to provide a burner which will produce practically complete combustion.

Another object is to provide means for spreading the flame in conjunction with a heat distributer or radiator.

Another object is to provide a spreader.

which will divide the flame and direct it toward a radiator.

Another object is to provide a slow draft below the spreader and a rapid draft above the spreader.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the'scope of what is claimed, without departing from the spirit of the inven tion.

One practical embodiment of the invention is shown in the accompanying drawings. wherein Figure 1 is a central vertical section of a heater constructed in accordance with my invention.

Fig. 2 is a plan View of the burner with the spreader and radiator, and the packing in the annular groove removed.

Fig. 3 is a detail cross section of one form of burner.

Referring to the drawings by numerals The burner consists of a block or plate 1 provided with an annular groove 2, and a central longitudinal bore 3. The outer wall of the groove 2 is bored at one point to receive a bushing 1, to the outer end of which is threaded one end of a supply pipe'5, and to its inner end is threaded the end of an annular pipe 6, which is provided with perforations 7. The pipe 6 rests on the bottom of the groove 2 and forms the fuel distributer of the stove. The groove 2 is preferably filled with broken particles 8 of fire clay, or with asbestos wool to spread and increase the flame.

A flame spreader 9, preferably in the form of a circular plate, is formed with depending lugs or feet 10 adapted to be seated upon the block 2, and ach provided with a reduced lower portion 11 which is received within the groove 2 and holds the spreader and its associated parts against lateral displacement. The spreader 9, is provided with a central circular aperture 12, the diameter of which is considerably less than that of the circular opening 3 of the burner. Pillars 13 risefrom the spreader 9, preferably immediately above the lugs 10, and support on their upper ends a radiator 14, which is a circular plate of greater diameter than the spreader 9, which in turn, is preferably of greater diameter than the tire box.

When gasolene, alcohol or other highly volatile liquids are used as fuels, the pipe 6 may be filled with asbestos wool 15, as shown most clearly in Fig. 3. Vhen crude oil or coal oil is the fuel used, no filler is placed in the pipe 6.

It is of course understood that this burner may be placed in any fire box, and supplied with liquid fuel under gravity or by forced feed. It is also evident that the burner may be made in various sizes and shapes to accommodate itself to the use to which it is to be put. The device may also be used as a separate heating or cooking unit, in which case it would be provided with legs, not shown, or otherwise suitably supported. and the radiator enlarged, if found desirable.

The operation of the device is as follows :Fuel supplied to the pipe 6 will flow from the perforations 7 and be ignited. The fuel will be scattered and spread throughout the width of the groove 2 by the particles of fire clay. The flame will strike the spreader 9 and spread out around the edge of the spreader and also in toward its center. A draft will then be set up through the openings 3 and 12, but, because of the greater cross sectional area of the opening 3, the upflowing air will pass slowly through this opening, and more rapidly through the opening 12. This will cause the flame which is deflected beyond the edge of the spreader 9 to be drawn in above the spreader and toward its center. That portion of the flame which was deflected by the spreader toward its center, will be drawn through the opening 12 by the rapid draft at this point. This action tends to direct the heat and flame on the center of the radiator causing violent heat in the chamber between the spreader and radiator and consuming all unburned carbon. This heat is deflected by the radiator toward the sides of the stove or furnace i-n the' fire box of which the device is being used.

distributor in the groove, a flame spreader above the burner provided with a central opening of less area than the opening in the burner and a radiator above the spreader.

2. A heater, comprising a burner provided with an opening, and a groove surrounding the opening, a fuel distributer in the groove, means for spreading the fuel throughout the groove, a flame spreader above the burner, and a radiator supported above the spreader, Intestimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
