ABSTRACT:
A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs a solenoid (76) and a thermocouple (18) in combination with a microswitch (80). When excess fuel enters the fuel chamber (40), a float (30) is urged upward, which forces a pin (28) upward, causing a microswitch (80) to open, thereby interrupting the electrical communication between the solenoid and thermocouple. As a result, a spring (24) can act to force an arm (14) upward, actuating the automatic wick extinguishing unit (42). Also, the mechanism prevents re-ignition of the wick (54) until the excess fuel is removed from the fuel chamber. When the fuel in the fuel chamber exceeds a predetermined level, a warning gauge needle (84) is deflected, alerting the user of the liquid fuel burner to a dangerous condition.
