PORTABLE BURNER.

Application led February 2i, 1924. Serial No. 699,209,

This invention relates to a portable burner designed primarily for burning out tree stumps and for similar purposes, one of the objects of the invention being to provide a simple and efficient structure which can be transported readily from place to place and will operate efficiently to destroy stumps.

Another object is to provide a structure of this character the frame of which constitutes a fuel conductor whereby fuel is directed from a container to burners suitably located relative to the stump to be burned.

Vith 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 may be made within the scope of whatis claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation showing the apparatus in position adjacent a stump to be burned one wheel of the container being removed.

Fig. 2 is a plan View.

Fig. 3 is an enlarged view partly in elevation and partly in section of one of the burners.

Fig. 4 is a section on line 4 4, Fig. 3, the

burner nozzle being shown in elevation.

Referring to the figures by characters of reference 1 designates a fuel tank or container having trunnions 2 extending in opposite directions therefrom and forming an axle for engagement by supporting wheels 3. Any suitable pump such as indicated generally at 4 may be mounted on the tank Iand can be operated by a lever 5 whereby air under pressure can be directed into the tank. The tank has an outlet pipe 6 provided with a controlling valve 7 and coupled to this outlet pipe by means of a union 8 is a detachable pipe section 9 on which are mounted sleeves 10 having pipes 11 projecting from them and constituting legs. This pipe 9 can be of any desired length and obviously the sleeves 10 can be slipped off of the pipe when it is uncoupled, thereby to allow the apparatus to be compactly stored while not in use or while being transported from place to place.

Pipe 9 may be coupled by a union 12 or the like to a short pipe 13 extending from a l`l -fitting 14 from which project oppositely extending pipe sections 15. These pipe sections open into valve casings 16 and from the valve casings are extended pipe-sections 17 preferably parallel to each other. On

.ea-ch of these sections is mounted a sleeve 18 having a pipe 19 extending therefrom and forming a leg. Unions 2O or the like can be employed for coupling the pipe sections 17 to short pipe sections 21 connected by elbows 22 to the supply pipes 23 of the burners. Each of the-se supply pipes open into one of a pair of connected elbows 24. rhe other elbow 24 of each is secured by means of a pin 25 to the ring 26. Extending through this ring is a pipe 27 open at its ends and forming the body of the burner. A tube 28 is extended from one of the elbows 24 and is coiled about one end portion of the pipe 27 so as to form inner and outer convolutions as shown at 29. Gne end of the pipe is attached to an elbow 30 communieating with another elbow 31. This last named elbow is located within the pipe 27 and has a nozzle 32 extending therefrom and arranged to discharge a jet of fuel longitudinally through that portion of the pipe 27 on which the coil 29 is mounted.

As will be apparent, when the apparatus is not in use the several parts can be disconnected where the unions are located. Vfhen it is desired to operate the apparatus, the part-s are assembled and the legs 11 and 19 will serve to support the pipes and burners so that the burners will be located at opposite sides of the stump S close to the ground. The valve 7 and those in casings 16 are opened so that fuel will iiow to the burners. The fuel is ignited and heat generated within the tubes 27 will result. in vaporizing of fuel in the coils 29 and the rapid production of a highly combustible gas. The flame will be projected from the burner, the fuel being supplied with air through the open ended tubes 27. By using this apparatus a stump can be quickly destroyed and it has been found in practice that it can be burned two feet or more be low the surface of the ground. By placing the legs 19 and 11 at different angles the burners can be adjusted vertically relative to the stump.

`What is claimed is The combination with a fuel supply pipe Cil constituting,l a support, .a ring -oonneoted to coils, one endfof theouter coil beingengaged andesupported by said pipe,and a coupling -by the eouplingfon"thezsupplypipe rand one 10 upon the pipe, of a pipe of relatively large endof-the inner coil being connected to the diameter open at its kends1 and ,extending nozzle n through and supportedby the ring, a nozzle In testimony that I claim the foregoing Within said large diameter pipe opening f to- -gas-zmyaown, I have hereto affixed my signa- Ward one end thereof, a vaporizing tube bent ture.
