FUEL BURNER.

Application filed December 28, 1826. Serial No. 157,509.

This invention relates to an improved fuel burner constructed for utilizing and efiectively consuming natural gas, oil, distill'ates and low grade fuels.

Briefly, the invention has reference to a structure of this character including an outer cylinder terminating at one end in an enlarged burner head and an inner cylinder located in spaced relation within the outer cylinder and terminating within the burner head, a low pressure air supply pipe leading into the inner cylinder, and a low pressure fuel supply pipe connected with and communicating with the interior of the outer cylinder.

My principal aim, is of course togenerally improve upon fuel burners of this character, by providing one which is typified by exceptional simplicity in construction, the parts being properly proportioned and associated in such a manner as to insure efficient operation, a low consumption of fuel, and an intensely hot flame.

Other features and advantages of the invention will become apparent from the following description and drawings.

In the drawings Figure 1 is a side burner.

Fig. 2 is a horizontal section.

Fig. 3 is across sectional view taken-approximately upon the plane of the line 33 of Fig. 1.

Fig. 4 is an end view looking in a direction from left to right in Fig. 2, the scale of the drawing being enlarged.

Fig. 5 is likewise an end view looking in the opposite end of Fig. 2.

Fig. 6 is a perspective view of the air .supply pipe.

Fig. 7 is a side elevation on an enlarged scale, of the inner cylinder, which constitutes an atomizing and vaporizing chamber.

Referring now to the drawings in detail, it will be seen that the reference character 1 designates a horizontally disposed enlar ed pipe which ma be conveniently referre to as the outer 'cy inder. At one end, this cy inder merges as at 2 into an enlarged extremity forming what may be referred to as a burner head 3. At the juncture of the head in the body portion of the cylinder,

'view of the complete and on the interior is a partition wall 4.

The inner cylinder which is of a smaller diameter and which is designated at 5 is As before stated, the structure effectively connected with the partition .wall and extends beyond it as at 6, the extending portion pro ecting into'the interior of the head \3. The opposite end of this inner cylinder is formed integral with the left han closed end 7 of the outer cylinder.

At this time, I would direct attention to the provision of a multiplicity of ports or perforations 8 adjacent the last named end of the cylinder. This cylinder 5' is open'at its opposite ends and spider arms 9 are disposed at the left hand end and serve as a mounting for an air supply pipe 10, which is 'of a relatively small diameter. It will be noticed that this pipe is mounted approximately at its center, one end portion projecting into the interior of the cylinder 5 and beyond the innermost ports 8 and the opposite end projecting outwardly andterminating in screw threads for connection for a suitable source of air supply. In this connection, I would state that a low pressure air supply tank (not shown) is employed and of course a. valve is included in the supply line to control the flow.

Extendin at right angles from the outer cylinder and connected integrally therewith in any appropriate manner, is the fuel intake 11 which is of a diameter greater than the pipe 10 and less than the diameter of the cylinder 5. It is yet to be pointed out that a supporting leg 12 is provided at the left hand end of the structure forsupporting it.

It will be obvious from Fi 2, that the fuel enters the structure throug the pipe 11, and in this connection I would remind the reader that the device is capable of consuming natural gas, and other low grade fuel. The air under pressure enters through the pipe 10. The atmospheric air enters through the openings existin between the "spider arms 11 and thus pro uces a suction.

Owing to the production of this suction both by the atmospheric air and the air under pressure,'the fuel is drawn into the space between the inner and outer cylinders and enters the interior of the inner cylinder through the ports 8. Here it is partially vaporlzed and becomes thoroughly mixed with the air. in the chamber produced by the inner cylinder 5. The charge is ignited at the discharge end of the cylinder, the flame being produced in the burner heads 3 in an obvious manner.

too

consumes the fuel and produces a highly intensive character of heat.

It is believed that by considering the foregoing description in association withthe drawings, a clear understanding of the construction, as well as the operation and advantages of the invention will be had. Therefore, a more lengthy description is thought unnecessary.

Minor changes coming within the field of invention claimed, may be resorted to if desired.

Having thus described my invention, what I claim as new is As a new product of manufacture, a fuel burner of the class described comprising an outer cylinder closed at one end, and merging at its opposite end into a slightly enlarged burner head, a partition wall on the interior of said cylinder and located at its point of connection with said burner head,

vided at the first named end with a multiplicity of fuel intake ports, radially disposed spider arms in the last open end of said inner cylinder, an air supply pipe connected with said spider arms and extending into the interior of the inner cylinder and beyond the innermost fuel ports, a right angularly disposed fuel ,intake pipe connected with the intermediate portion of the outer cylinder, and a supporting leg connected with the closed end of said outer cylinder.

In testimony whereof I afiix my signature.

WILLIAM J. HADDOCK.
