Abstract
The object of the invention is to provide an apparatus for the cooling and quenching of destructive fires. The Fire Extinguishing Capsule comprises two double-walled hemishapes which are sealed together by an equatorial belt seal which may be raptured in order to disperse the extinguishant in the capsule. The capsule may be suspended in sire or from a hook and ladder system or a helicopter in the case of forest fires or oil well fires or transported by sled to a fire scene.
Claims14
A fire extinguishing capsule for cooling and extinguishing destructive fires, comprising:
- a double-walled upper hemishape having an upper hemishape outer shell and an upper hemishape inner shell;
- a vacuum space between said upper hemishape outer shell and said upper hemishape inner shell;
- a double walled lower hemishape having a lower hemishape outer shell and a lower hemishape inner shell;
- a vacuum space between said lower hemishape outer shell and said lower hemishape inner shell;
- a window ring adapted to be interposed and sealed between said double walled upper hemishape and said double walled lower hemishape;
- means for securing and sealing said double walled upper hemishape to said double walled lower hemishape;
- a cooling extinguishant chamber formed between said double walled hemishapes by the securing and sealing together of said hemishapes;
- means for filling said chamber with cooling fire extinguishant material.
