  • Patent number: 9096290
    Abstract: A storage device for holding a drain plug for a boat is disclosed. The storage device provides a place to store the drain plug when it is removed from a drain hole for the boat. The storage device includes a reminder system using an emergency stop lanyard (ESL) present on nearly all powerboats. The storage device holds both the ESL and the drain plug. The storage device is designed so that the ESL cannot be removed without first removing the drain plug. Thus, an operator cannot start a boat's engine without first removing the drain plug from the storage device to gain access to the ESL, allowing the ESL to be refitted onto an operating system for the boat's engine. The act of handling the drain plug reminds the operator to re-install the drain plug into the drain hole.

  • 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: 6615760
    Abstract: An automatically sealing boat draining device to be mounted in a hole passing through the transom of a boat, includes: a cylindrical housing with a drain hole; a ball valve assembly mounted within and removable from the drain hole; and a plug for sealing the drain hole. The ball valve assembly includes a ball, a sealing ball seat component, and a flow through ball seat component that are held within the drain hole by a retaining ring. A flow of water from the outer end toward the inner end of the drain hole causes the ball to seat in the sealing seat component and seal the drain hole. A flow of water from the inner end toward the outer end of the drain hole causes the ball to seat in the ball flow though seat component and permit the flow of water through the drain hole.

  • Patent number: 6604481
    Abstract: A method and apparatus is disclosed for permitting the passage of conduits through the hull of a boat without the creation of additional holes. A conduit-accommodating passageway is defined through the boat's scupper which bypasses the check valve that is associated with the scupper to prevent backflow. An annular body having a radially-extending conduit-accommodating passage communicating between its O.D. and its I.D. is positioned with respect to the scupper so that the fluid passing through the scupper and check valve passes through the generally annular body's I.D. while conduit passing through the radially-extending passage passes through the scupper but bypasses the check valve.

  • Patent number: 6477971
    Abstract: A bilge drainage system for a boat having a through-transom drainage passageway has a through-transom pipe connected to an externally-mounted flange and connected internally to a manually or electronically operated stopcock located near the bottom of the bilge such that the stopcock may be opened, and bilge water drained to the sea, when the boat is traveling through the water on a plane.

  • Publication number: 20020134291
    Abstract: Diagnostic strips of the kind which are exposed to biological fluids such as blood or urine to detect or monitor medical conditions are cut sequentially from elongated cards by a reciprocating shear blade. The cards may be ones which exhibit defective areas that should not be included in the finished strips. Blade motion seats each newly cut strip on a movable strip carrier which abuts the blade during the cutting operation. The carrier then travels a nondefective strip to a pickup location where it is precisely positioned and picked off of the carrier for emplacement in a housing. A strip with a defective area is carried further to a discharge location where it is released into a waste receptacle. This enables more economical manufacture of diagnostic strips by efficiently making use of nondefective areas of cards that have defective areas.

  • Patent number: 6338309
    Abstract: An improved bilge drain system for an inboard motorboat is disclosed having a drain closure assembly that is operated from a position external to the engine compartment. The drain closure can be a valve operable by a handle, wherein the handle is accessible outside of the engine compartment when closed by an engine compartment cover. The handle, which may be located adjacent to the engine compartment or on a dashboard of the motorboat, may also be configured to provide the user with a visual indication of the open and closed status of the drain closure.

  • Patent number: 6227132
    Abstract: A boat drain plug with cable tether including a cylindrical plug portion adapted for coupling with the drain of the boat. The cylindrical plug portion has an upper end, a lower end, and a cylindrical side wall therebetween. The upper end has a block secured thereto. The block has an aperture therethrough. The lower end is receivable within the drain. A length of safety cable is provided that is formed into a lower loop and an upper loop. The lower loop is coupled with the aperture of the block of the plug portion. A swivel loop is provided having a central pivot member with opposed upper and lower looping members. The lower looping member couples with the upper loop of the length of safety cable. A safety line is provided having an upper end and a lower end. The lower end couples with the upper looping member of the swivel loop. The upper end is couplable with the tie down cleat of the boat.

  • Patent number: 6050867
    Abstract: A drain system is provided for a marine vessel in which three types of drain operations can be performed at one common location near the transom of the marine vessel. A multiple conduit structure is provided with a plurality of fluid passages extending at least partially through its structure. A first fluid passage allows the bilge of the boat to be drained. A second fluid passage allows multiple locations on the engine to be drained through a common port. A second sealing plug is provided to close the second passageway that prevents fluid communication between the various fluid conduits used to drain the cooling water of the engine. A third fluid passage is provided through the multiple conduit structure to allow lubricating oil to be drained from the engine.

  • Patent number: 5966080
    Abstract: A drain plug warning system includes a first member that can be attached to a transom or other wall of a watercraft and a second member that is shaped to be received within an aperture that is formed through the first member. To drain water from the watercraft, the drain plug or second member is removed from the aperture of the first member, and water is allowed to drain through the aperture. If the second member is not replaced within the aperture to a predetermined location relative to the first member, a magnetically sensitive component near the aperture assumes a state that will cause an alarm under certain predefined conditions such as when an operator activates a key switch mechanism of the watercraft. The magnetically sensitive component can be a Hall effect element or other magnetically sensitive component.

  • Patent number: 5727820
    Abstract: A flange for a drain pipe extending from the side of a large, flat-bottomed, open container, such as the cockpit of a boat, has its upper portion fitted along the inside of the side of the cockpit, but the lower portion of the flange is bent inwards along the bottom of the drain pipe in an "L" shape to rest tightly against the bottom or deck of the cockpit, which brings the bottom of the drain pipe close to the deck of the cockpit, to drain off as much as possible of the water that builds up in the cockpit due to rain, spray, or other sources.
