Abstract
A fire hose nozzle assembly employing separable receiver and nozzle sections which are releasably retained in assembled relation by a removable fastener to permit rapid disassembly and reassembly at the scene of a fire in order to remove accumulated debris and other foreign material from the interior of the nozzle assembly so that normal operation can be rapidly and easily restored. The shiftable valve member and valve seat of a flow control and shut-off valve assembly are respectively mounted in the receiver and nozzle sections of the nozzle assembly. Movement of the valve member toward and away from its seat to vary the characteristics of the flow from the nozzle is achieved by a bail-type control handle that is pivotally mounted on the housing of the receiver section. The removable fastener which retains the nozzle section in the receiver section also permits adjustment of the position of the control handle so that engagement of the valve member with its seat is assured when the control handle is shifted fully in a direction to close the valve assembly. An adjustable brake member is mounted in an enlarged head of one of the trunnions which support the control handle and permits adjustment of the force required to move the control handle and to hold the handle in an adjusted position.
