  • Patent number: 8020505
    Abstract: A method and apparatus for securing a surface water vessel to a floating station. The surface water vessel may be an unmanned surface vehicle, and the floating station may be attached to a larger parent ship. According to the invention, the surface water vessel includes a forwardly projecting elongated probe and the floating station includes a receiver having a receiver opening for receiving the elongated probe therein. The elongated probe includes a spherical tip having a circumferential groove. The receiver includes movable spheres that are moved into engagement with the circumferential groove, thereby locking the probe within the receiver. This locking arrangement secures the surface water vessel to the floating station.

  • Patent number: 7013823
    Abstract: A mechanical warning flag system for a water ski boat. A first plate is coupled for rotation underneath the rope pylon. A second plate is coupled to the first plate and includes a vertical portion with an arcuate opening. A lever plate is pivotally coupled to the vertical portion of the second plate and includes a lever arm that receives one end of a bias spring and travels in the arcuate opening. The lever plate includes a pair of rope holders through which the tow rope is threaded. One rope holder is part of the pivotal connection, and the other is located on a distal portion of the lever plate. Since the lever arm is located between the rope holders, tension applied to the tow rope forces the lever plate downward thereby lowering the warning flag. In the absence of rope tension, a bias spring urges the lever plate upward to raise the warning flag.

  • Patent number: 5364145
    Abstract: This invention is directed to rotary release hook apparatus comprising a rotatable release hook of a generally circular configuration. In the release hook there is a recess for receiving a cable or a rope or a chain. The rotary release hook apparatus can be on a dock or an oil well platform or a barge or another suitable device. The cable or rope or chain cam connect with a boat or a ship or a barge or other large similar object. In the release hook there is a notch. There is a rotatable pawl having a projecting finger projecting into the notch to prevent rotation of the release hook. There is a rotatable member having a recess. Part of the pawl bears against the rotatable member. There is a release lever arm connecting with the rotatable means for rotating the rotatable member to allow the pawl to move into the recess and away from the rotatable release hook. This allows the rotatable release hook to rotate to release the cable or rope or chain.

  • Patent number: 5123374
    Abstract: An improved releasable toggle locking mooring hook (10) having a releasable hook (20), toggle linkage (89), a stop/release mechanism (119), a self locking safety latch (126) and a self release mechanism (251) adapted to provide a secure locking mooring hook and a low friction, low effort releasing means while mooring hook is under heavy tensile load. In the mooring of ships, boats and barges to a dock or oil well platform, a line, usually under tension, is run from the ship to a mooring means mounted on the dock or platform. When it is desired that the ship leave this moorage, this mooring means can be actuated manually, mechanically or by a pre-set tensioned self releasing means to release mooring line and thus, allow the ship to sail. This mooring means is identified as a releasable toggle locking mooring hook (10) of this invention.

  • Patent number: 4827861
    Abstract: A towing system adapted for quick and safe release of a towing tug from a barge string. Cable cleats and bits are mounted on the tug and on the barge string to position and support a cable which is connected into a winch apparatus to tightly connect the tug and the barge string together. A cable loop is looped around and retained by a cable retainer arm pivotably connected into a frame mounted to retain the cable. The retainer arm forms a distal finger retained to latch the arm into cable retaining position by a latch lock device. The latch lock device is pivotably mounted in the frame to retain the distal finger. A catch device forming a catch hook is pivotably mounted to the latch block device. A retainer bar is fixably mounted with the frame to engage the catch hook for keeping the latch block in position to retain the finger. A lever arrangement is pivotably connected to the frame for pushing the catch hook free of the retainer bar device.

  • Patent number: 4826229
    Abstract: An improved portable cable release mechanism for mounting on the deck of a tow boat, tug, ship or dock and used to tow and dock barges, boats and ships, which mechanism is designed to receive one end of a tow cable or docking cable in order to secure and selectively release the vessels. The cable release mechanism includes a pelican hook pivotally attached to a frame which can be removably mounted on a dock or secured to the deck of a tow boat, ship or barge by means of a clevis plate. A sliding keeper normally secures the pelican hook in closed configuration in the frame and release of a towing or docking cable from the pelican hook is automatically effected by activating an air or hydraulic cylinder having a piston provided in cooperation with the keeper ring. This action extends the cylinder piston and forces the keeper from engagement with the pelican hook, allowing the pelican hook to pivot rearwardly responsive to the load on the cable.

  • Patent number: 4813731
    Abstract: An improved cable release mechanism for mounting on the deck of a tow boat, tug or other tow vessel or vehicle comprising a rigid frame connectable to said tow vessel having pivotally connected thereto a pelican hook swingable through at least 180.degree.. The tow strain exerted by the tow cable passes along a line on the plane along which the axis of rotation of the pelican hook lays. As a result, when the device is used for towing, there is no rotational bias exerted on said pelican hook. In one embodiment, means for securing and/or releasing the pelican hook are comprised of a generally triangular shaped release member means having an upper pin and a lower pin positioned on the upper and lower side of the free end of the pelican hook, respectively, wherein when said release member is pivoted toward the release position, the lower pin exerts an upward force on the pelican hook and the upper pin is allowed to clear the way for the pelican hook to swing to the open position thereby releasing the cable.

  • Patent number: 4389907
    Abstract: In the mooring of ships and boats to a dock or an oil well platform, it is necessary to have a line running from the ship or boat to the dock or platform. The line can be more or less tight and must be fixed so as to allow, relatively, sudden movements of the ship or boat with respect to the dock or platform. Then, when it is time for the ship or boat to sail away from the dock or platform, it is necessary to disengage the line from the fastening means from the dock or platform. 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 or platform. Then, the person on the dock or platform can, by means of an electric control, if desirable, at a remote position from the fastening means, actuate the fastening means to allow the line to slip away from its fastening means and also to allow the ship or boat to sail away from the dock or platform.

  • Patent number: 4290382
    Abstract: In a system for interconnecting buoyant float sections in an articulated manner, a receiver assembly for automatically engaging a connector of a type having a longitudinally inclined nose section and a pair of transverse locking grooves. The receiver assembly comprises a receiver housing with an interior channel, a U-shaped locking guillotine member and a locking assembly. The locking guillotine is slideably introduced into a transverse slot in the receiver housing; it rests on a pair of locking bars in the locking assembly with the legs of the locking guillotine extending part-way into the interior channel of the receiver assembly. As the connector is extended into the channel, the legs of the locking guillotine contact the inclined surface of the connector nose section, causing the locking guillotine to slide up within the slot until aligned with the connector locking grooves. The locking guillotine then falls, the guillotine legs sliding down within the locking grooves, to effect interengagement.
