Title: Device for preventing flareup in barometric-type liquid fuel burners by preventing excessive temperature levels at removable fuel tank

Abstract: A safety device for preventing uncontrolled burning in barometric-type liquid fuel burners of the type where a removable fuel tank (60) feeds a fuel chamber (40), which supplies the fuel to a wick (54), via a sump opening in the upper surface of the chamber (40). A fusible link (28), which is affixed to a tank guide (12) via a support (30), is connected to an arm (74). The arm (74) is in turn connected to a lever (78) in a hinged fashion. The lever (78) is attached to a support (82) in a hinged fashion. A face (80) is present on the lever (78) at the end of the lever (78) distal to the end connected to arm (74). The face (80) is proximate to an automatic wick extinguishing unit (42). Should the temperature of fusible link (28) exceed a predetermined level, it will open irreversibly, allowing arm (74) to move downward, which in turn causes lever (78) to rotate about support (82), forcing face (80) upward, which actuates the automatic wick extinguishing unit (42).
