1. A floating fountain device for use in a swimming pool comprising:

  • a central housing having a plurality of hollow, radially projecting arms thereon each having a pod-like float on its outer end, said housing and said arms being buoyant to float the device on the surface of a pool, and one of said floats having a separate bottom wall sealed to the underside of the float;

    means defining an inlet for admitting water under pressure into a lower end of said housing and an outlet for water to flow out of the upper end of the housing;

    a fountainhead connected to the central housing for receiving flowing pressurized water that passes through the housing and ejecting the water from the housing to form a fountain of water;

    an electric lamp mounted in said one float on said bottom wall thereof, and positioned to direct a beam of light into the fountain of water;

    a waterproof sealed envelope in said housing supported in spaced relation with the housing to form flow passages from the inlet toward the outlet;

    an electricity generator sealed in said envelope and having wires for electrically connecting the generator to said lamp through one of said arms;

    a water turbine mounted in said housing above said envelope and having inlet openings for receiving water under pressure from said flow passages and forming driving jets for the turbine, said turbine being positioned beneath said outlet to deliver the water from the turbine to the fountainhead;

    and a magnetic coupling having a first coupling half carried by said turbine and a second coupling half spaced beneath said turbine within said envelope and coupled to said generator to drive the generator and thereby provide electricity to said lamp.
