Abstract
Abstract of the Disclosure The invention provides a weed exterminator in which a hot air output flow is generated by an electrically heated blower and the combustion of a fuel such as lignite, char-coal or pit coal. The device for generating the hot air flow is composed of a fuel supply container and a hot air passage joining one another in a combustion chamber provided with an exhaust port for the escape of the hot air flow. At its juncture with the combustion chamber, the fuel supply con-tainer is provided with a fuel retention device acting to retain the fuel in such a manner that a portion of the fuel projects into the combustion chamber and into the hot air flow generated by the electrically heated blower. The hot air passage is connected to the blower in such a manner that the hot sir flow impinges on the fuel, whereby the latter is ignited, as a result of which a hot a flow is generated at a substantially higher temperature.

Weed Exterminator ~escription ,~"-. - "~ "~:
The invention relates to a heat-radiation weed exterminator comprising a combustion chamber for the combustion of a fuel ;;~-and a heat radiation surface.
When plants are e~posed to a heat radiation, an irreversible heat damage will occur at a limit temperature of 80 C or above, causing the plants to die within a few days due to rupture of the cell diaphragms of the plant at this limit ~ ;
temperature. ;~
A weed e~terminator functioning on the heat radiation -~
principle is already known and employed for the e~termin~
ation of weeds on sidewalks, road shoulders, sportsgrounds and the like. This known weed e~terminator comprises a fuel `
container for a gaseous fuel, a hand-pushed wheeled frame, a combustion chamber mounted on the wheeled frame and having ; ;
a burner and an outlet port for the heat radiation, a ~; manganese grid disposed in the combustion chamber, and a -~
fuel supply pipe connected the fuel container to the burner.
For the e~termination of weeds, the gas supplied from the fuel container is combusted in the burner, whereby the manganese grid disposed in the combustion chamber is heated to 900 C. At this temperature, the manganese grid emits an infrared radiation which is directed through the outlet port onto the weeds to~ be e~terminated. In this,manner the infra-red radiation can be used for e~terminating weeds by pushing -;
the wheeled frame o~er the surface areas to be treated. This weed e~terminator is rather e~pensive, howe~er, due to its intricate construction and the employ of the rare metal manganese.

:
It is an object of the present invention to provide a weed extermintor of simplified and therefore less expensive construction.
~ ,."~
Proceding from the features set forth in the generic clause of claim 1, this object is attained by the characterizing features of this claim.
The present invention is based on the finding that a very high radiation output is obtainable by the combustion of a solid fuel in a forced air flow, and that the employ of the electrically heated blower renders superfluous the otherwise necessary complicated procedure of igniting the solid fuel.
A further advantage of the invention results from the fact that the fuel supply container containing the fuel required ~i~
for the generation of the heat radiation, for instance lignite, charcoal or pit coal, is integrally connected to - -~
the combustion chamber. The fuel supply system is thus integrated in the overall construction of the weed e~termin~
ator to thereby facilitate the handling thereof thanks to its low weight and compactness. The employ of the above mentioned solid fuel furthermore results in an improved handling safety of the weed e~terminator by the elimination of the danger of spontaneous ignition e~istin8 in the case of a gaseous fuel. The solid fuel is moreo~er less problem-atic as regards its storage.
The preferred embodiment ~according to claim 2 offer~i the advantage that the fuel supply container permits the storage of a fuel supply which is fed to the combustion chamber in a simple manner by way of the communication port.
: -The impro~ement according to claim 3 results in the advantage that, due to the location of the fuel supply container above .

.:: . ~
the combustion chamber, the fuel retained by the fuel ~-retention device will always slip downwards by the action of gravity as it is being consumed.
The provision of claim 4 offers the advantage of permitting the heat irradiation of the weeds to be more effectively ~ ;
controlled by the location of the combustion gas exhaust port laterally of the combustion chamber rather than at the bottom thereof, the heat radiation flow being further -;
improved by the provision that the air outlet passage opens into the combustion chamber at the side thereof opposite ; ~ ;
the exhaust port. ~
.; . . . - .:
.: :
The improvement according to claim 5 results in the advant~
age that any n~n-combusted fuel particles are held back by ~;
the exhaust port grid until their combustion is completed.
The improvement according to claim 6 offers the advantage that the space device acts to maintain a constant spacing betweenthe ground and the combustion gas e~haust port.
.
The embodiment according to claim 7 results in the advantage that the mounting device permits the electrically heated blower mounted thereon to be pushed over the ground rather than having to be carried.
The improvement according to claim 8 offers the advantage that the provision of a tubular socket on the combustion chamber permits the! bldwer to be detached from the combust~
ion chamber, and that the employ of a commercially available hot air pistol as the blower permits the appliance to be operated with a fuel haYing a high ignition temperature. ~

The weed exterminator illustrated in the drawing comprises -~
ahot air blower mounting device l provided at one end with a -:
clamp ring 2 and a rotatably mounted wheel 3 at the other end, an electric hot air pistol 4 having its outlet barrel secured to clamp ring 2, and a heat radiator 5, the latter being composed of a cylindrical fuel supply container 6 and .
a cylindrical hot air passage 7 joining one another within - -~
a cylindrical combustion chamber 8 under a predetermined angle 9. Combustion chamber 8 is coa~ially aligned with fuel supply container 6, the symmetry a~is 10 of fuel supply container 6 intersecting the symmetry a~is 11 of hot air ;~
passage 7 under said predetermined angle 9. Hot air passage 7 is stabilized by being integrally connected to fuel supply container 6 by a wedge-shaped web portion 12. The upper end of fuel supply container 6 is hermetically closed by a :~
closure member 13. At its juncture with combustion chamber 8, . :
fuel supply container 6 is provided with a fuel retention device 14 acting to retain a fuel body 15 in supply con-tainer 6. The forward facing side of combustion chamber 8 is formed with an e~haust port 16 for the escape of a hot air ~ . .
flow, with an e~haust port grid 17 covering port 16. ~-~
Disposed from the outside on the bottom of combustion :
chamber 8 is a spacer device 18. Fuel retention device 14 is composed of st least two projections disposed on the inner ~:
wall surface of fuel supply container 6, one such projection extending radially towards symmetry a~is 10 of fuel supply container 6, the other e~tending parallel to the symmetry a~is of hot air passage 7 from the point of juncture of fuel supply container 6iand hot air passage 7, said juncture point being disposed at a predetermined distance above the ~
projection e~tending radially towards symmetr~ a~is 10. Fuel ~ ~:
retention device 14 may also include additional projections ;~
e~tending radiall~ towards symmetry a~is lO and disposed at ~ :
symmetrical circumferential spacings, or the projection e~tending radiall~ towards symmetry a~is lO may be of '.'; -'",.~' -;,' ~::
annular configuration. The free end of hot air passage 7 is designed to conform to the shape of an outlet nozzle 19 of ;
hot air blower 4.
In a modification of the described embodiment, the heat radiator may simply comprise a hot air passage opening into ;
a combustion chamber, the latter being provided with an exhaust port for the escape of the hot air flow at a locat-ion opposite the opening of the hot air passage. In this embodiment (not shown) of the weed e~terminator the fuel would be disposed in the combustion chamber.
The operation and function of the weed e~terminator shall now be explained in detail. Preparatory to use of the apparatus, the outlet barrel of hot air pistol 4 is pushed into clamp ring 2 of mounting device 1 to thereby fixedly secure hot air pistol 4 to clamp ring 2. Subsequently the end of hot air passage 7 is slipped onto outlet nozzle 19 of hot air pistol 4. The weed exterminator will thus be supported on the ground by wheel 3 and spacer or slide shoe-18, and can be displaced over the ground by gripping a handle 20 of hot air pistol 4, or a pushing shaft 21 secured to mounting device 1. Closure member 13 is removed from fuel supply container 6 for permitting the latter to be charged with a fuel supply 15, whereupon closure member 13 is replaced onto the upper end of fuel supply container 6.
Since the diameter of the body of fuel 15 is smaller than that of fuel supply container 6 and greater than that of fuel retention device 14, the fuel body 15 is freely movable in container 6 and solely retained therein by retention device 14, with its flattened end projecting into combustion ~-chamber 8. For the generation of a heated air flow, hot air pistol 4 is activated by actuating its switch 22, the temperature of the heated air flow being then adjusted by the actuation of temperature control knob 23. As a result,;~ `~
, - . ;'',,''~':' .:" - .
~ 2023368 - ~
6 ~ -a hot air flo~ exits from outlet nozzle 19 at the selected temperature of for instance 600 C. The hot air flow is directed through hot air passage 7 into combustion chamber 8 so that it impinges on the end portion of fuel body 15 ~-projecting into combustion chamber 8. The hot air flow heats the fuel to a temperature above its ignition point to thereby initiate its combustion. The ignition of fuel 15 results in the temperature of the hot air flow being raised from 600 C to 1300 C. The hot air is e~hausted from combustion chamber 8 through exhaust port 16, with exhaust port grid 17 acting to retain any loose fuel particles, without, however, hampering the hot air flo~ in any appreciable manner. The particular design of fuel retention device 14 permits fuel body 15 to slide towards combustion ~
chamber 8 by its own weight and at the rate of the combustion -~i process, the predetermined angle 9 between fuel supply container 6 and hot air passage 7 being of decisi~e import~
ance for the controlled combustion of the fuel. The hermet-ically sealing of the upper end of fuel supply container 6 by closure member 13 ensures that only the po~tion of fuel body 15 projecting into combustion chamber 8 is ignited , rather than all of the fuel at once. The fuel body 15 may be made of compacted lignite, charcoal or pit coal. After the hot air e~iting from e~haust port 16 has attained a temper-ature of 1300 C, the weed e~terminator can be properly operated by guiding it over the weeds to be destroyed, the spacing device 18 ensuring a constant distance to be main-tained between e~haust port 16 and the ground surface. ;
The described appliance is of course not only useful for the e~termination of weeds, and may be employed in any applications requiring a high infrared radiation output. ~ `

~he device may thus be used for readily removing oil stains from paved or concrete parking lot surfaces, such stains being known to be highly resistant to the attack of even extremely aggressive chemical substances. Even paints or ~
fixedly adherent chewing gum residues are readily removable. ;
The appliance is also particularly useful for superficially softening or melting tarmac surfaces to the purpose for instance of embedding zebra strips therein, and may be generally employed for rapidly drying, surface-melting or heat-curing any suitable material.
