Abstract
Abstract A fire fighting monitor apparatus has a casing having at least one fluid inlet thereinto and a plurality of fluid outlets therefrom. The casing has a rotatable joint formed therein for rotating 360° all of the fluid outlets together. A circular ball joint swiveling nozzle is mounted on each fluid outlet for directing fluid for the outlet separately so that each nozzle can be separately controlled for direction and spray pattern for a plurality of water streams controlled by one fireman simultaneously. Each outlet can have dual swivels each rotating on a ball joint to provide greater flexibility in directing each nozzle. Outlets can also supply separate water hoses if desired. Additional reducing adapters are connected to nozzle outlets for using a variety of nozzle sizes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A fire fighting monitor comprising in combination: a casing having at least one fluid inlet thereinto and a plurality of outlet therefrom; rotary joint means formed on said casing for rotating said fluid outlets together; and a swiveling nozzle coupling coupled with dual swiveled ball joint couplings to each fluid outlet for directing fluid from each outlet separately for each nozzle, each nozzle being separately controlled for direction in spray pattern and each ball joint having a passageway therethrough having an annular radius surface thereon and attached to the outlet with an attaching collar having internal threads therein for locking said ball joint in position by rotating said collar whereby a fire fighting monitor allows separate fluid streams of controlled fluid dispersion patterns.
Claim 2
Dependent Claim
