Removable fire hydrant nozzle with improved locking structure

摘要

A removable hydrant nozzle with a locking arrangement for securing the nozzle in a nozzle opening. The locking arrangement includes an axially movable slide configured to selectively engage a portion of the hydrant adjacent the nozzle opening, such as a lug mouth in a quarter-turn fitting. The slide is mounted to a slide housing and is spring loaded. In use, the slide automatically retracts as the nozzle is inserted into the nozzle opening and automatically extends into locking engagement with the mouth when the nozzle becomes fully seated. Once engaged, the slide prevents removal of the nozzle until manually disengaged. The slide may be movably mounted on a pair of shoulder bolts. The slide may include a paddle that extends outwardly where it is accessible to the operator. The nozzle may include a handle and a seal fitted onto the inner axial end of the nozzle.
