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.
