    Patent number: 4219084
    Abstract: A fire extinguishing apparatus delivering an extinguishing agent through a barrier surrounding a structure into the interior thereof. The apparatus includes an elongated tubular nozzle body which has a pointed penetrating head carried on one end of the tubular body. A source of extinguishing agent is coupled to the opposite end of the tubular body and is fed therethrough and passes through passages adjacent the head for delivering the extinguishing agent to the interior of the structure. A slidable mass is carried on the tubular body on a remote end of the tubular body from the penetrating head. By manipulating the slidable mass and bringing such in contact with an abutment the force imparted to the tubular body causes the head to penetrate the structure.
