  • Patent number: 4658748
    Abstract: In the mooring of ships, boats and barges to a dock or oil well platform it is necessary to have a line run from the ship or boat or barge to the dock or platform. The line running from the dock or platform to the ship or boat or barge is under tension. This invention is directed to a RELEASEABLE HOOK which, automatically, trips and releases the line when the tension on the line exceeds a predetermined tension. The ship or boat or barge at that time is free to move. The increase in the tension in the line maybe be brought about by rough water or by a wind or other causes. This RELEASEABLE HOOK is a design to trip and release the line without an operator. The tension in the line, when it exceeds a predetermined tension or pressure on the hook, will cause the hook to automatically trip.

  • Patent number: 4034992
    Abstract: In the mooring of ships and boats to a dock, it is necessary to have a line run from the ship or boat to the dock. The line can be more or less tight and must be fixed so as to allow relatively little movement of the ship or boat with respect to the dock. Then, when it is necessary to allow the ship or boat to sail away from the dock, it is necessary to disengage the line from the fastening means on the dock. This invention relates to a fastening means whereby a line can be positioned to the fastening means for securing the ship or boat adjacent to the dock. Then, the person on the dock can mechanically actuate the fastening means to allow the line to slip away from the fastening means and also to allow the ship or boat to sail away from the dock. This fastening means is identified as a releasable hook. When it is desired to have the ship or boat fixedly secured with respect to the dock, the fastening means is in a locked position to firmly position the line.
