  • Patent number: 7159528
    Abstract: Disclosed is an apparatus and methods for a plurality of users to work and/or play underwater with a supply of breathable air. The breathable air is taken from the atmosphere above the surface of the water. The air is sent to one or two submerged users. The apparatus and its components are enclosed in a water resistant enclosure encapsulated by an inner tube which floats on the surface of the water. The apparatus provides breathable air to one or two users from a flexible air supply line, which runs from the apparatus to each submerged user. The air pumps of the apparatus push a constant flow of breathable air to each user. Each user inhales air from the apparatus with a mouth piece that is connected to the air supply line which is connected to the air pumps. Equipment such as regulators, tanks or reservoirs are not needed. The apparatus is powered by a dry cell battery and does not require fuel to operate.
