  • Patent number: 5799916
    Abstract: A bracket for being mounted to a flotation device such as a drum is manufactured as a single piece which includes spaced apart parallel sidewalls having a curved bottom edge for mating with the curvature of the periphery of a floating drum and has end walls spanning between the sidewalls at opposite ends of the sidewalls and a top wall opposite of the lower curved edges of the sidewalls in which top wall there is a central opening on opposite sides of which there are flat load bearing surfaces. A clamping device having the properties of a turnbuckle connects between the ends of strap which wraps around the drum and hooks to opposite ends of the turnbuckle so that turning of the body of the turnbuckle holds the ends of the strap together to effect frictional gripping of the bracket to the drum.

  • Patent number: 4974538
    Abstract: An improved polyethylene float drum for marine structures has a preformed polystyrene core which is configured to dimensionally conform to the interior surfaces of the polyethylene walls of the drum. Because the preformed core fills the entire enclosure of the float drum, a dimensionally controlled float drum is provided with superior strength characteristics.

  • Patent number: 4947780
    Abstract: A buoyant module which is useful in the construction of modular docks, marinas and the like is fabricated by providing a buoyant member and applying a protective sheet over a portion of the member, and pumping a fiber-reinforced concrete layer over one face of the buoyant member. Structural rods extending through the layer are interconnected with peripheral whalers, which in turn permit the buoyant member--concrete layer combination to be joined together with similar modules in a unitary, low cost and facile construction.

  • Patent number: 4940021
    Abstract: A floating dock includes a plurality of float modules comprised of containers having opposing walls, a deck with opposing edges mounted in spaced relationship above the float modules, and a pair of wales extending along opposing walls of the float modules and opposing edges of the deck. Compression rods extend between the wales and act on the pair of wales such that the compression rods exert compression force on the float modules and deck. A compression beam or plywood panel extends between the opposing walls of the container below the compression rod to create a box beam in combination with the wales and deck, therefore rigidifying the dock to enhance its portability on land and wave resistance properties in water. The float modules are spaced apart longitudinally of the dock to allow wave transparency and wash space for debris. The space between the deck and float modules forms a passageway for utility conduits.

  • Patent number: 4928616
    Abstract: A construction transportation system comprises at least one transport assembly having gross dimensions generally corresponding to those of a standard freight container. The transport assembly comprises at least two construction components. Each of the two construction components has a first gross dimension whose maximum value is generally equal to C.sub.1 /x, where C.sub.1 is the width of a standard freight container, and x is greater than or equal to 1. Each of the two components has a second gross dimension perpendicular to the first dimension whose maximum value is generally equal to C.sub.2 /y, where C.sub.2 is the length of a standard freight container, and y is greater than 1. Each of the two components has a third gross dimension perpendicular to the first and second dimensions. At least a first side of each of the two components extends in the directions of that components' first and third dimensions, and that first side is provided with connectors.

  • Patent number: 4928617
    Abstract: Polyethylene float drums are constructed as modules, in various configurations, and then assembled into various modular systems to float a variety of structures. All float drum modules utilize at least one flat, perpendicular side wall to insure accurate assembly of the float drum modules into a flanged load bearing modular float assembly having desired float characteristics.

  • Patent number: 4927394
    Abstract: This invention is directed at a buoy which includes a body portion having a handle portion extending from one end and an engagement means extending from the other. The body portion of the buoy may be hollow and may be filled with flotation material. The handle portion may include teeth or annular ribs which are engagable by lock rings. The lock ring for engaging the teeth has an inwardly extending tab and the lock ring for engaging the annular ribs may have biased inner surfaces or inwardly extending tabs. The lock rings hold a second body portion in circumscribing relation to the handle portion.

  • Patent number: 4920921
    Abstract: A modular marine flotation collar for aquaculture applications is disclosed. Component collar segments are sealed by bulkheads including a connecting flange. Standard component collar segments may be assembled into a desired configuration by flange-to-flange connection of adjacent collar segments. A plurality of elongate tubular members having arcuate recesses conforming to the outer perimeters of supporting collar segments are arranged transversely atop the collar assembly so as to provide for the construction of an elevated walkway. The invention provides for a pen divider which is movable within the perimeter of the flotation collar for partitioning an area within the assembly.

  • Patent number: 4915052
    Abstract: A method for restoring and maintaining buoyancy for floatplane floats by inserting an inflatable air bag into the leaking compartment in the float and inflating the air bag until the water in the float is expelled from the float and the air bag seals the leak. A puncture resistant air bag also may be permanently installed in a floatplane float at the time of manufacture in order to prevent leaks.

  • Patent number: 4896620
    Abstract: A buoy (10) carries a light (16) at the upper end of a mast (14). The lower end of the mast (14) is connected to a buoyant body (12) which is weighted to present a maximum diameter zone (20) slightly below the water level when the buoy (10) is at rest in the water. The body (12) tapers inwardly both above and below the maximum diameter zone 20. A towing bar assembly (18) is provided on one side of the buoy (10). It includes an upwardly and outwardly sloping guide bar (30) connected at its upper end to a tow bar (36). An eye (50) at an end of a control line (46) is slidably received on the guide bar (30). An initial tug on the control line (46) causes the eye (50) to slide upwardly along the guide bar (30) until it engages a bight (38) of the tow bar (36). The bight (38) is positioned radially outwardly from the maximum diameter zone (20). Then, when the control line (46) is pulled upon, it pulls the buoy (10) into the water.
