ABSTRACT:
A nozzle construction including inlet and outlet ends is provided and the inlet end of the nozzle is adapted to be secured in the discharge port of a fire extinguisher. The outlet end of the nozzle is of a configuration designed to afford a stream-type discharge of any fire extinguishing material (dry chemical powder, liquid and/or pressurized gas) therefrom, whereby the fire extinguisher may be hand held and have the discharge from its nozzle directed toward the base of a fire to be extinguished. However, the nozzle is designed to be utilized on a heat sensing and automatic fire extinguisher of the wall type and the outlet end of the nozzle includes a discharge dispersion element removably supported therefrom and designed, when retained in position, to effect a wide dispersion of the stream of any fire extinguishing material being discharged through the nozzle. The purpose for widely dispersing the stream discharge of fire fighting material from the fire extinguisher as a result of its automatic operation when wall mounted is to enable the discharge of the fire extinguisher to completely saturate a room area into which the fire extinguisher is automatically discharged and the purpose of the removal dispersion element being to enable removal of the latter for the purpose of manually fighting a localized fire.
