ABSTRACT:
A fire extinguishing apparatus for oil wells has a plurality of containers for containing fire extinguishing material connected to a main fire extinguishing container. The main fire extinguishing container has a conduit leading from a valve in the neck thereof to the interior of a bell nipple positioned on an oil well blow out preventor. A bracket attached to the main container supports a manually operable spring loaded mechanism which is adapted, upon release of the spring loaded plunger contained therein, to open a valve in the neck of the main container and allow the content of the several containers to flow under pressure through conduits into the interior of the bell nipple thus extinguishing a fire therein. An additional valved line is attached to the bell nipple at one end thereof with the opposite end connected to a source of fire extinguishing materials located at a remote area onshore so that if the manually operable spring loaded mechanism cannot be operated on the oil well platform, then the source of fire extinguishing material at the remote location may be operated so as to cause fire extinguishing materials to flow through the additional valved conduit into the interior of the bell nipple extinguishing a fire therein.
