Abstract

The present invention features an improved chimney fire safety device. The device includes a cylindrical canister that is affixed in the top of a chimney or stove pipe. The canister contains one or more membranes containing extinguishing compounds. A metal dish is disposed in the bottom of the canister, and holds the extinguishing compounds in place until needed. The walls of the canister adjacent the metal dish are coated with a frictionless, high-temperature, anti-seize material, so that the metal dish will drop from the canister without difficulty at the proper time. A fuse cap is affixed to the bottom of the canister. The fuse cap is contiguously held to the metal dish, and keeps it in place until a predetermined temperature of an uncontrolled fire is reached. Thereafter, the fuse cap will disintegrate and allow the metal dish to drop from the canister. The metal dish will not leak extinguisher chemicals, because the heat conductive nature of the metal dish will distribute the heat across the contiguous fuse cap surface, and prevent hot spots from developing in the fuse cap.
