摘要： An emergency release latch mechanism for a hinged cover of a hatchway construction, wherein the cover is heavily spring biased to open position but is normally restrained in closed position by the latch mechanism. The mechanism includes an emergency-actuated release member such as a low-temperature fusible metal link which, through a release mechanism which reduces the tensile load on the link, retains a latching dog in engagement with a shackle pin on the cover but assures positive disengagement therefrom to release the cover to open position in the event of actuation of the emergency-actuated release member. The latch mechanism is typically positioned at the center of the hatch but the release member and emergency-actuated release members are disposed near a wall of the hatch so that the latch mechanism may easily be set or reset by a person at the periphery of the hatch by securing a cable connecting the latch mechanism and release mechanism.
