Patent number: 4927394Abstract: 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.Type: GrantFiled: October 24, 1988Date of Patent: May 22, 1990Inventor: Thomas Galgana

Patent number: 4920921Abstract: 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.Type: GrantFiled: July 25, 1988Date of Patent: May 1, 1990Inventor: Gordon M. Ochs

Patent number: 4915052Abstract: 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.Type: GrantFiled: November 30, 1988Date of Patent: April 10, 1990Inventors: Gregory C. Reeser, Terry Wolgamot

Patent number: 4896620Abstract: 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.Type: GrantFiled: February 1, 1989Date of Patent: January 30, 1990Inventor: Harry E. Jones

Patent number: 4887654Abstract: 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 betwen the deck and float modules forms a passageway for utility conduits.Type: GrantFiled: October 8, 1987Date of Patent: December 19, 1989Inventor: David H. Rytand
