Patent ID: 6877981

Claim:
A portable gas cooking range, comprising: a) a burner; b) a piezoelectric igniter positioned adjacent to the burner; c) a holder for a gas canister, and mean for supplying a gas from the holder to the burner; d) an adjustable gas regulator for varying a flow of the gas to the burner, the gas regulator incorporating a magnetic gas valve having a press button for opening the gas valve, and a revolvable lever having one arm for operating the press button, and another arm for operating a flame failure safety device, said device incorporating a thermocouple located in close proximity to the burner and operably connected to the gas valve in the gas regulator; e) a substantially horizontal feed pipe for connecting the gas regulator to the burner; and f) a manually operable flame regulating knob having a projecting part for causing rotation of the revolvable lever upon manual operation of the knob with consequential simultaneous operation of the safety device and of the press button for opening the gas valve and causing the operation of the piezoelectric igniter to ignite the gas flowing through the feed pipe to the burner; whereby the thermocouple actuates the magnetic gas valve so as to cut off the gas flow to the burner if the thermocouple senses a sudden reduction in temperature at the burner as a consequence of the flame going out.
