Abstract:

A fire hydrant wrench is provided with a chatter-thread arrangement that permits a threaded handle to be pushed, rather than manually threaded, into engagement with a fire hydrant fixture. A quick release trigger similarly permits the handle to be quickly withdrawn without unthreading. Faster operation of hydrants, with consequent savings of lives, results. Other improvements are also disclosed, including reversible, replaceable gripping teeth that tend to prevent even a loosely coupled wrench from falling off a fire hydrant.
