ABSTRACT:
An improved nozzle apparatus rapidly convertible, while operating, between spray and foam forming modes of operation. An elongate rigid generally cylindrical first conduit member receives surfactant bearing solution at an inlet port thereof and directs the solution under pressure to a spray forming nozzle connected at an outlet port of the first conduit. A second elongate conduit member coaxially slidably overlies the first conduit member and is movable relative thereto between extended and retracted positions. When in its retracted position, the second conduit member exposes the spray-forming nozzle, which is then enabled to direct a spray pattern of the solution longitudinally outward from the apparatus. When in its extended position, the second conduit member encompasses the spray-forming nozzle, and aspirates the spray therefrom with air to form foam which is ejected longitudinally outward from the second conduit member. Foam dispersing means are provided at the outlet port of the second conduit member for spreading the ejected foam in a fan-shaped pattern. Fastener means connecting the first and second conduit members enables rapid positioning of the second conduit member between its retracted and extended positions. Handle means are provided for enabling an operator to hand-carry the nozzle apparatus and to directionally aim the spray and foam patterns ejected therefrom to a target area.
