Abstract:
A fire fighting monitor comprising:a casing having a main inlet pipe for receiving water under pressure from a water source and a plurality of outlet arms extending from said main inlet pipe, each of said casing outlet arms having an elbow formed therein and said casing having a main rotary joint formed therein for rotating said plurality of outlet arms and said main rotary joint having an annular rack gear engaging a worm gear which worm gear has a handwheel attached thereto for rotating said main rotary joint and each said outlet nozzle, and each said outlet arm having an outlet arm rotary joint therein positioned between said main inlet pipe and each said outlet arm elbow for rotating a portion of each said casing outlet arm and each said outlet arm rotary joint having an annular rack gear engaging a worm gear which worm gear has a handwheel mounted thereto for rotating each said outlet arm and a swiveling nozzle mounted thereon for rotating said swiveling nozzle;the swiveling nozzle attached with a swiveling nozzle coupling to each said outlet arm for directing water from each outlet arm separately, each said swiveling nozzle being separately controlled for directing water therefrom in separate output directions, each said swiveling nozzle having a ball joint having a passageway therethrough and having a threaded collar thereover for tightening said swiveling nozzle coupling into a predetermined outlet position whereby the fire fighting monitor allows separate fluid streams of controlled water dispersion patterns to provide greater control of the output from the fire fighting monitor; andsaid casing having a pressure gauge mounted thereto for measuring the water pressure in said casing.
