2 Claims. 15853) This invention relates to a burner, and it is one object of the invention to provide a device of this character of such construction that either gasoline or kerosene may be burned, improved means being provided for converting the liquid fuel into a gas and then mixing the gaseous fuel with air to form a combustible mixture.

Another object of the invention is to so form the device that, when it is in use, the liquid fuel during its conversion into a gas will be passed through a tortuous passageabout a tube constituting a combustion. chamber and the fuel subjected to heat in such a manner that it will be very effectively transformed into a hot gas;

which then passes through a. pipe line and is delivered into the combustion chamber.

Another object of the invention is to provide a device of this character having means for draining off liquid fuel at the front end of the burner when found necessary,

It is another object of the invention to provide a burner having a fuel pan wherein fuel may be burned as a preliminary heating means for the body into which the liquid fuel is delivered and transformed into a gas.

Another object of the invention is to providean improved type of hood which serves as a shield for the tubular body and prevents atmospheric cooling of the body when the burner is in use.- I

1 Another object of the invention is to provide a burner including a tubular body and a tubular combustion chamber together with plates or disks mounted about the inner tube in sucha manner that they will be securely but detachably held in place and, when in place, provide the turtuous pathway wherein the liquid fuel is transformed into a hot gaseous fuel.

The invention is illustrated in the ing drawings, wherein:

Figure 1 is a sectional view taken longitudinally of the burner in a vertical plane,

Figure 2 is a transverse sectional view taken alongthe line 22 of Figure 1, and I Figure 3 is a perspective view of two of the disks carried by the inner tube.

Thebody l of this burner consists of a tube of a predetermined length and diameter formed:

of strong metal. Within the tubular body is disposed an inner tube 2 which is also formed of strong metal having its end portions externally threaded so that disks 3 and 4 mayhave their annular flanges or necks 5 and 6 screwed upon end portions of the inner tube and thus securely but removably mount the end disks or closures upon end portions of the inner tube. These end .disks or closures are of the proper diameter to accompany- 'l and converted from a liquid form into a gaseous state, and in order to cause the fuel to move in a tortuous path through this conversion chamber,

'there havebeen provided a plurality of disks 8 and 8' which fit snugly about the inner tube 2 proper angular relation to the tube and the body. These disks are applied after one of the end disks has been applied and when the secondv end disk is screwed onto the tube all of the disks will be firmly held in place. When, however, it is necessary to remove any of the disks for thorough cleaning or replacement thereof, it is merely necessary to unscrew one of the end disks after withdrawing the tube and the disk from the body and the disks 8 and 8 may then be easily slid longitudinally off the tube. and 4 may be securely but removably mounted within' ends of the body I in any desired manner, but they are preferably welded therein so that they will be firmly held in place and a tight joint formed between margins of these disks and the walls of the tubular body. Small openings or perforations I0 and II are formed in the disks- 8 and 8', and while these disks are of a duplicate formation, they will be so secured upon Therefore, the fuel must follow a tortuous path-' way formed in the tubular bod-y about the inner tube as it flowsthrough the space 1 and the liquid fuel which enters through the pipe line l2 will be'very effectively converted into a hot gas which passes out through the pipe line [3.

In order to effect a preliminary heating of the body l,'.there has beenprovided a heating'pan' [4 which is disposed under the body and provided with upward-1y extending arms l5 formed of 'metal strips which have their upper end portions offset inwardly, as shown in Figure 3, and

secured against opposite sides of the body I by fit snugly within the tubular body I and close the v ends of a chamber 1 about the inner tube. Fuel is to be passed through the conversion chamber screws Hi. This pan is to hold a liquid fuel which, when ignited,'will cause the body I to be heatedto such a temperature that, when the valve I! of the pipe line I2 is opened and liquid fuel flows'through this pipe line into the front end of the space or chamber 1, it will make contact with hot metal and be converted into'a gas. This 'gaswill be more in the nature of a vapor,

and as it follows the tortuous pathway into which the space or chamber I0 is formed by the bafile plates or disks, it Will be subjected to heat for such a length of time that it will be converted The end disks 3 into a gaseous state in a very effective manner and a hot dry gas delivered into the pipe line [3. This pipe line extends longitudinally of the burner, and at the forward end of the burner extends downwardly, as shown at [8, and then towards the center tube 2, as shown at l9.. This portion IQ of the pipe line [3 extends in axial alinement with the tube and carries a nozzle from which a jet of gas is discharged into the elongated combustion chamber 2| formed by the tube. As the gas rushes through the combustion chamber 2|, air will be drawn into this chamber to mix with the gas and forma combustible mixture, and when this combustible mixture is lighted, the tube 2 together with the disk carried thereby and the tubular body will be heated to-a very high temperature and the fuel which continues toflow into the chamber 1 will be quickly converted into a hot and dry-gas. A drain pipe 22 controlled by a valve 23 1eads from the bottom of the chamber l8 adjacent the front end of the body I so that in case too much liquid fuel is initially fed into the conversion chamber or the valve I1 is not shut tightly when the burner. is not in use and liquid fuel leaks through the pipe line l-2, this fuel may be drawn off through the drain pipe.

It is desired to shieldthe body I from atmospheric air currents which are'liable to cool it to some extent when the burner is in use. Therefore; there has been provided a metal hood or shield 24 formed of sheet metal which isbent so that this hood or shield may be disposed-in straddling relation to the tubular body, as shown in Figure 2. shield rests upon sleeves 25 provided about the vertically disposed portions l2 and I3 of the pipe line l2 and I3 sothat the upper portion of the hood-will be'supported in the desired spaced relation to the tubular body. The depending side walls 26 of the hood are weldedor otherwise firmly secured against the metal strips or arms l5, and in these side walls are formed openings 2-! which constitute ventilating openings.

When this burner" is in use, it is-set upas shown in Figure 1, and a quantity of liquid fuel poured into the heating pan It. This fuel is then ignited and allowed to burn so that the tubular body will be thoroughly heated. When the fuel in the pan is almost consumed, the valve 11 is opened and liquid fuel will-flow through the pipe line l2 into the front end of the conversion chamber 1, and upon striking the hot wall of the body, it will be converted into a gas or vapor which flows through the openings II! at the top of the first baffle plate or disk 8 with suflicient force to cause it to strike against the adjacent baffle plate or disk 8'. The gasor vapor then moves downwardly and through the opening ll of the disk 8' and upon striking the next disk 8, it will flow upwardly and through the opening Ii] of this disk. This movement is continued as the vapor or gasfollows the tortuous path defined by the disk, and upon reaching the rear end of the conversion chamber, the fuel will have been transformed or converted into a gas which is hot and dry. This gas flows upwardly into the pipe line l3 and after following this pipe line is discharged through the nozzle 20 into the combustion chamber 2| where it will mix with air.

sucked into the combustion chamber by the jet. of gas and thegas and air will mix in the combus-.

The upper portion of this hood or tube.

tion chamber to form a combustible fluid. This combustible fluid is then ignited and a very hot fiame will be produced which may be employed for any purpose for which the burner is designed and will serve very effectively to highly heat the tube 2, the disk and the body I of the burner. In view of the fact that the burner is shielded by the hood 24, undesired cooling by atmospheric air currents will be prevented. When operation of the burner is no longer desired, it is merely necessary to close the valve 11 and the flow of liquid fuel through the pipe line l2 will be shut off. When draining is necessary, the Valve 23 may be opened and any fuel which has accumulated between the end disks 3 and the first disk or baffle 8 will flow out through the drain pipe 22. When it is desired. to thoroughly clean the burner or replace any of the bafiie plates or disks, the end disks 3 and 4 are released from their connections with the. walls of the tubular body I- and the tube 2 and the disk carried thereby may then be slid longitudinally out of the body. One of the end disks may then be unscrewed and the baffle plates or disks slid longitudinally off the A thorough cleaning may then be performed. including reboring of the perforations I0 and II if necessary and the device reassembled, new baffle disks being applied to the tube if found necessary.

Having thus described the invention, what is claimed as new is:

1. A burner of the character described comprising a tubular body. a tube extending longitudinally through said body axially thereof, end
