ABSTRACT:
A fire hydrant nozzle assembly which permits a bronze fire hydrant nozzle to be readily and simply attached to a cast iron hydrant barrel without the use of lead caulking, screw threads, or other methods generally requiring machining. Un-intentional removal of the bronze nozzle as a result of the application of relatively high torque typically required to remove a protective cap is effectively prevented. To provide these features, a bronze nozzle member is retained within a hydrant boss member by means of a bayonet type or breech lock type mechanism involving cooperating lugs, and a resilient seal such as an O-ring is provided. For locking the nozzle member in its installed position, a pin element passes through a pair of corresponding apertures in confronting surfaces of the boss and nozzle members. The installed position is positively defined by respective locating engagement surfaces carried by the boss and nozzle members, which surfaces serve to limit rotation. The corresponding apertures can always be aligned even though they are pre-formed or pre-drilled. Preferably, the locating engagement surfaces are configured and positioned such that locking rotation of the nozzle following insertion into the boss occurs in a direction opposite to the direction of the threads on the outlet end of the nozzle such that when the nozzle cap is removed the locating engagement surfaces resist the torque involved.
