ABSTRACT:
A capture and alignment mechanism which locks a deployable body to a sheave assembly. The sheave assembly is connected to a carriage which rides on a boom positioned above the deck of a ship and extends over the ship's st. The mechanism includes a capture body having a conical shaped inner surface and a pair of capture pins positioned 180 degrees apart near the bottom of the capture body. A cable is terminated by a cable termination assembly which couples the deployable body to one end of the cable, while the other end of the cable is wrapped around a winch. The termination assembly includes a termination cone having an outer surface which aligns with the conical shaped inner surface of the capture body when the deployable body is hoisted upward to the capture and alignment mechanism. The capture pins are moved to an open position by a pneumatic cylinder allowing the termination cone to align with the inner surface of the capture body. When alignment of the termination cone and capture body occurs, air pressure is turned off which results in the capture pins returning to a closed position. The deployable body is lowered and its weight is suspended by the capture pins on a wave-like surface on the bottom of the termination assembly, allowing the deployable body to rotatably center itself.
