Fire nozzle assembly
First Claim
1. A nozzle for forming a generally sphere-like water spray pattern, said nozzle comprising:
- means for coupling said nozzle to a water delivery hose for receiving water therefrom;
a plurality of rings for forming said spray pattern, which rings include;
a central ring positioned in a generally transverse attitude to the water flow direction;
a first group of nested and conically shaped rings positioned rearwardly of said central ring, the surfaces of successively rearwardly positioned rings sloping increasingly rearwardly;
a second group of nested and conically shaped rings positioned forwardly of said central ring, the ring surfaces of successively forwardly positioned rings sloping increasingly forwardly;
each of said first and second group of rings having a plurality of substantially radial water directing and fog forming slots, said slots having angularly shaped corner surfaces for creating turbulence; and
retainer means securing said rings in stacked and assembled relation.

Abstract
There is disclosed herein a firefighting nozzle forming a generally sphere-like water spray pattern. The nozzle includes a coupler for coupling the nozzle to a water delivery hose. The nozzle also includes a plurality of rings for forming a spray-like pattern. The ring includes a central ring positioned generally transverse to the water flow direction. A first group of nested and conical rings is positioned rearwardly of the ring and the surfaces of all successively rearwardly positioned rings sloping increasingly rearwardly. A second group of nested and conical rings is positioned forwardly of the central rings. The ring surfaces of successively forwardly positioned rings sloping increasingly forwardly. Each of the rings in the first and second group have a plurality of substantially radial water directing and fog forming slots, each of which has angularly shaped corner surfaces for creating turbulence.
In addition, there is disclosed an elongated nozzle for extending the nozzle into a room or space. There is also disclosed a winch mechanism for remotely extending the nozzle to distant positions.
