ABSTRACT:
A handy gas torch controlled by a valve control mechanism to eject gas into a combustion chamber inside a nozzle for burning, said valve control mechanism comprising a valve control sleeve having a bearing plate fastened therein, a gas tube inserted through said bearing plate, said gas tube having a valve attached thereto at the bottom and stopped at a valve port through which gas is discharged out of a gas tank, a screw nut screwed up with said gas tube at the top above said bearing plate, a guide member mounted on said screw nut at the top, and spring means constantly forcing said valve to stop at said valve port. Moving said valve control sleeve causes said valve to disconnect from said valve port for discharging gas out of said gas tank into said nozzle for combustion. Releasing upward pressure from said valve control sleeve causes said valve to stop said valve port again. Said nozzle comprises a combustion tube having a commutator fastened therein through which a very hot flame is produced for welding. A catalyst may be fastened in said nozzle spaced from said commutator with a jet combustion chamber defined therebetween so that a heat flow can be produced therethrough for melting a stick of glue or for drying purpose.
