  • Patent number: 4031839
    Abstract: For removing oil from the bilge area and fuel tank filler area of a boat, an oil absorbent pad is constructed with an outer wide mesh structural envelope confining and reinforcing an inner containment envelope of woven synthetic crepe material that will absorb oil with a wicking action while repelling water and which will contain therein granular open pore synthetic foamed resin capable of absorbing and retaining the oil without leaking. Pads are provided in the bilge area of boats to act alone or in combination with bilge pump filters, and they are provided as a ring around the fuel tank filler opening to prevent spillage during the taking on of fuel by the boat.

  • Patent number: 3941073
    Abstract: The portable water bailing device of the present invention includes a housing having a plurality of openings therein adjacent the lower end thereof. Within the housing is a water pump connected to a tube for directing the water from the bottom of the boat outwardly over the edges thereof. The water pump is driven by a direct current motor which is connected in series with a battery. Also in series with the battery and motor is a limit switch which is actuated by a float within the housing. As the water rises within the housing, the float actuates the switch which in turn actuates the pump.
