ABSTRACT:
A safety latch mechanism for use in connection with a pressure vessel of the type having a shell, a closure for removably closing an access opening defined by the shell and a locking ring rotatably supported by the shell adjacent the access opening for releasably locking the closure in access opening closed position. The mechanism features a first latch member mounted by the shell for releaseably preventing unlocking rotation of the locking ring relative to the shell and a second latch member mounted by the locking ring and responsive to movement of the first member for releasably preventing relative rotational movements of the locking ring and closure. The first member is operatively associated with a vessel exhaust valve, which tends to constrain unlatching movements of the first and second latch members, when the pressure within the vessel exceeds a safe level at which the closure may be operated without the possibility of injury to person or property.
