Sea Cocks Patents (Class 114/198)
  • Patent number: 8622010
    Abstract: A pneumatic seacock retrofit is provided for convenient closing of all or a portion of the seacocks, whether as a matter of every day convenience or for use in an emergency, in which all of the vessel's seacocks can be pneumatically closed at the same time, leaving the possibility of selectively overriding seacock closure, with all control valves operating to provide a momentary pulse of air to the rotary actuators and then return to a neutral position, leaving the actuators free for further control. Moreover, an operator is free to manually close a valve in the event that the pneumatic system fails.

  • Patent number: 7699013
    Abstract: A water uptake device for directing water flow into a moving boat that allows the volume and pressure of the water flow entering the device to be adjusted from full force to no flow at all by simple adjustment of how much of its scooping member protrudes beyond its through-hull fitting into the water stream. Water enters the device through an opening in its deployable scooping member, and operator positioning of the scooping member relative to the through-hull fitting, including complete withdrawal of the scoop into the distal end of the through-hull fitting, is remotely accomplished so that the operator can remain at the helm. Multiple devices can be used on the same marine vessel, with all devices mounted on the bottom of its hull, in a standard fashion for through-hull fittings mounted below the waterline. Applications may include the filling of ballast bags for the sport of wakeboarding.

  • Patent number: 7530370
    Abstract: The invention is directed to an adapter used in a marine fluid handling system to prevent thread mismatch between a thru-hull fitting and in-line valve. The adapter includes a head with a male NPT thread and a bore with a female NPS thread. The adapter is threaded to a thru-hull fitting with a male NPS thread that extends through a hole in a boat hull. The adapter is also attached to an in-line valve having a female NPT thread. The valve may be mechanically fastened to the adapter to prevent thread disengagement. When the valve fails, the valve is easily removed from the adapter that remains attached to the boat hull, and a replacement valve is attached to the adapter.

  • Patent number: 6176248
    Abstract: A submerged, valve assembly for controlling flow of fluid (e.g. ballast water) to and from a reservoir (e.g. a ballast tank of a ship. The valve assembly is comprised of a valve which is controlled by a hydraulic valve actuator. A fluid-tight housing encloses the actuator so that any leaking hydraulic fluid will be contained within the housing and will not pollute the surrounding fluid in the tank. The assembly includes a means for detecting any hydraulic fluid which may leak into the housing.

  • Patent number: 5947047
    Abstract: A boat has a seacock operatively attached to the hull and movable between open and closed positions. The seacock is operatively connected to a discharge pump, which in turn is connected to a sewage holding tank. An electrical switch is actuated in response to the position of the seacock, and control circuitry is connected to the seacock electrical switch and the discharge pump to prevent operation of the pump if the seacock is closed (or in any position aside from fully open). An indicator, such as one or more light emitting diodes, is also actuated in response to the seacock electrical switch position, and another indicator, such as one or more light emitting diodes, is connected to the discharge pump and indicates when that pump is operating. The electrical switch is waterproof and meets marine vessel ignition prevention and electromagnetic compatibility requirements, and typically is actuated in response to the position of a manually actuable (e.g. rotatable) handle of the seacock.

  • Patent number: 5452677
    Abstract: A hull and backup valve assembly for a submarine includes a valve body made of the same material as the hull; thus, the valve body can be welded directly to the hull. The flow path of the valve is straight and disposed at an angle relative to the surface of the hull, facilitating the removal of the valves' components for inspection and repair. Corrosion resistance is obtained through the extensive use of clad overlays and internal barriers that completely protect the steel surfaces from seawater contact. The valve stem is made of a titanium alloy and mates directly to the rack of a hydraulic actuator, thereby further reducing the parts and volume required for the valve assembly.

  • Patent number: 4846209
    Abstract: A scuttle valve is provided for flooding a torpedo. The scuttle valve inces a housing which is fitted through the hull of the torpedo. The housing has a bore which when vacant, serves as a port to enable water to enter the torpedo. A piston is slidably mounted within the bore of the housing and is spring biased towards the interior of the torpedo. An explosive bolt which is threaded into the piston extends through a tapered plate which cams a retainer ring across the interior end of the piston and into an interior annular recess in the housing to restrain the piston within the bore. When the explosive bolt is actuated the bolt breaks and the retainer ring contracts to allow the spring to force the piston into the interior of the torpedo. Thus, water enters through the open bore of the housing and floods the torpedo.

  • Patent number: 3993012
    Abstract: A vessel for transport of a floating buoyant cargo such as barges, lighters, and pontoons, wherein the cargo is partially supported in the vessel by its own buoyancy. The hull has an imperforate bottom shell with rigid submarine cargo-supporting and hull-reinforcing structure, a bow, a stern, side walls providing a series of buoyancy compartments, and a hollow enclosed interior including a cargo hold. Water can be introduced into or expelled from the buoyancy compartments to adjust the draft, trim, and list of the vessel. The cargo-supporting and hull-reinforcing structure has openings communicating with the hold and providing a bottom chamber that is always flooded during the voyage but can be pumped out for maintenance and repair. A series of water conduits pass to the ocean at intervals along the length of the hold, each conduit being located (when the vessel is level) at all points above the top of the bottom chamber.
