Patent ID: 7159528

Claim:
An underwater breathing apparatus comprising a) a water-resistant enclosure contained inside a circular inflatable tube that floats on the surface of a body of water; b) a plurality of air pumps that are each connected to a flexible air supply line which is connected to a combination quick disconnect and check valve that is connected to an air collection header that generates a constant flow of breathable air to at least one user; c) a plurality of air supply lines that supply said breathable air to at least one user; d) at least one mouthpiece that is connected to said air supply line and to the user's mouth; e) a dry cell battery that is connected to said air pumps that enable a supply of breathable air to reach at least one user for an extended period of time; f) a top and bottom lip that encircle both the top and bottom of the water-resistant enclosure that enables the circular inflatable tube in its deflated state to first be mounted around the water-resistant enclosure and then to be inflated and operate as an air transporter and as a floatation device; g) a safety flag mounted outside of the water-resistant enclosure that indicates the presence of at least one user in the area to other people in the area; h) a safety warning light mounted on top of the water resistant enclosure that can be is turned on by a switch by the user when the device is used in darkness; i) an air collection header mounted inside the water resistant enclosure that is connected to an internal check valve that connects the air pumps to the air-supply lines that transport air to at least one user; j) two fresh air vent tubes that supply air to the air pumps and prevent water entry into the water-resistant enclosure k) an air-inflated circular tube that, when inflated with air, encapsulates the water-resistant enclosure and keeps it afloat; l) a circular rubber inner tube that is inflated with air by a short air inflation line; m) a tether line made of a strong material that allows the water-resistant enclosure to be pulled by the user that are combined into a floating underwater breathing apparatus that enables at least one user to breathe through a mouthpiece while underwater.
