Abstract: A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs an excess fuel containment compartment (24) which receives any excess fuel which might be fed to the fuel supply chamber (40). The excess fuel causes a receptacle (20) in the compartment to move downward. Through a retaining arm (82) and actuating arm (78), such movement communicates with a removable tank lift mechanism in response to the excess fuel condition. Also the mechanism prevents re-insertion of the removable tank (60) to its proper seating position until the danger of flareup is removed. This safety device also alerts the user of the liquid fuel burner to a dangerous condition by a mechanism comprising a highly visible warning gauge needle (34). In addition, the burner can be readily serviced and restored to operation should an excess fuel malfunction occur.

Abstract: A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs an excess fuel containment compartment (24) which receives any excess fuel which might be fed from a removable tank (60) through a spring-loaded valve in the removable tank cap (61) into fuel supply chamber (40). The excess fuel causes a receptacle (20) in the compartment to move downward. Through a retaining arm (82) and lever (66) such movement activates a pin-drop mechanism. Activation of the pin-drop mechanism closes off the valve in the removable tank cap. Also the mechanism prevents re-opening of the fuel tank valve until the danger of flareup is removed. This safety device also alerts the user of the liquid fuel burner to a dangerous condition by a mechanism comprising a warning gauge needle (34). In addition, the burner can be readily serviced and restored to operation should an excess fuel malfunction occur.
