  • Patent number: 6079635
    Abstract: Water display nozzle shields for allowing water display nozzles to be positioned and operated below the surface of the body of water without constant entrainment of water from the body of water affecting the nozzle characteristics. In one embodiment, a rotatable shield assembly is controllably rotatable between first and second positions. In the first position, the shield assembly is positioned over the nozzle of the water display and substantially sealed with respect thereto, the shield extending from adjacent the exit end of the nozzle which is positioned below the water level, to a position above the water level. When rotated to a second position, the nozzle shield, as well as the nozzle, are both disposed below the surface of the water so as to not be visible.
