  • Patent number: 4358058
    Abstract: Firefighting apparatus for rapidly dispersing water spray into a super heated atmosphere with as little effort on the part of the fire fighter as possible includes a nozzle providing a whirling fog cone wide angle discharge coaxial with a conventionally supplied narrow angle forward discharge, by means of water pressure spinning of a rotatable section having angled fog heads; control is by handle which can provide for forward discharge, or combination forward and wide angle fog cone discharge, or can shut off all flow; to provide optimum control with smooth flow a transverse cylindrical shape valve body is decentered relative to the bore of the system and has a tapered passage through it; the invention also gives the fire fighter the option of injecting the apparatus into an involved structure without subjecting himself to any more danger than necessary.
