ABSTRACT:
A releasable connector for connecting a shackle bolt on a liferaft to the depending end of a davit cable is set in a safe condition for boarding and lowering of the liferaft. In the safe condition, a hook member supports the shackle bolt and is itself locked in its supporting position by a latch member. A coupling spring connected between the hook member and the latch member operates to one side of its dead-center position to urge the latch member into the locking position. A first downward pull on a lanyard causes a pawl member to engage a tooth on the latch member to move the latch member from its locking position to a drive position in which the coupling spring operates to the other side of its dead-center position and urges the latch member into its drive position. When the liferaft takes up a floating position on the water, the load on the sackle bolt is relieved and automatic release of the shackle bolt effected under the action of the coupling spring which turns the hook member out of its supporting position. If the automatic release fails, the lanyard is given a second pull which brings the pawl member, which has returned under spring loading, to engage a second tooth on the latch member and cause the latch member to execute a driving movement in which it displaces the hook member out of its supporting position for release of the shackle bolt. A first pull on the lanyard results only in the cocking of the connector for automatic release and cannot result in manual release. A second pull on the lanyard is required to effect manual release.
