Abstract:
Wildfire water-supply hose having a QD nozzle with an outer sleeve adapted to engage a firefighter's backpack water bladder's QD connector. The combination male QD nozzle/female QD system permits rapid and easier bottom-up filling of the bladders without dismounting the tank from the firefighter's back, by inserting the QD nozzle into the female QD fitting on the bottom of the backpack bladder. The QD nozzle tip is long enough to open the internal spring-biased shut-off valve in the female QD connector when inserted. Upon opening the supply line valve, water flows into the backpack bladder until full. The supply valve is closed and the QD nozzle is withdrawn from the bladder female QD connector. Rotation of the QD nozzle outer sleeve controls water flow from stream, to spray to mist. The QD nozzle is also used with other types of nozzles on dual fittings having 3-way valves, e.g., fog nozzles.

Claim (Index 4):
A wildfire fighting fluid nozzle assembly comprising in operative combination:\n a) a male quick-disconnect nozzle assembly having an outer tubular sleeve configured with exterior angled shoulders disposed medially of a forward spray tip, said shoulders being adapted to releasably engage a separate female quick disconnect connector assembly when inserted therein, said outer tubular sleeve terminating in an internal angled taper; b) an inner stem fitted within said outer tubular sleeve, said stem terminating at a forward end in a spray tip and an opposed end including a female threaded union, said spray tip cooperating with said internal angled taper of said outer sleeve to provide selectable fluid delivery depending on the spacing of said spray tip from said taper; c) said tubular outer sleeve and inner stem being cooperatively threaded to permit selection of the spacing between said spray tip and said taper to provide control of fluid ranging from stream, to spray, to mist by rotation of said outer sleeve with respect to said inner stem; d) said outer tubular sleeve having a nose section between said exterior shoulders and said spray tip of length sufficient to fully open an internal spring-biased axially reciprocable valve of a female quick disconnect connector assembly, when said nozzle is inserted into and engaged with said female quick disconnect connector assembly; and e) so that when said female quick disconnect connector assembly is fitted to the bottom of a container and said fluid nozzle assembly is fitted to a fluid supply hose, said container can be automatically filled from the bottom from said supply hose.
