ABSTRACT:
A fire-fighting tool having a perforated pointed forward end is designed to automatically maintain its water-emitting portions in place within the interior of a burning building, without manual attention thereto, after the wall or roof of such a building have been pierced with same. Rearwardly directed ports are carefully arranged so as to produce non-intersecting streams of water. These ports emit water under high pressure when the pointed heavy tool is attached to a fire hose and serve to extinguish the fire at the inner surface of the outside wall, and at the same time prevent the tool from being ejected rearwardly, which would be the normal result of the passage of water under high pressure from the fire hose through such a tool. A cement block or frame wall can be pierced with the tool while manned by a single fire-fighter, who may retreat from danger while the tool, because of its construction, remains in place to effectively extinguish the fire, because the rearward urging normally experienced by such a tool has been completely eliminated.
