ABSTRACT:
An automatic fire extinguishing apparatus including a fire sensor, a swivel chamber and an expansible hollow rod secured to the chamber. When a fire is detected by the fire sensor, the swivel chamber is rotated about a vertical axis in accordance with the output of the fire sensor until the rod is directed to the fire source. Then a pressurized fire extinguishing agent contained in a bomb is introduced into the rod through the chamber to expand the rod toward the fire source. The expansion of the rod is stopped when the end of the rod is adjacent the fire source and the free end of the rod is opened, so that the fire extinguishing agent is discharged toward the fire source.
