  • Apparatus for removing liquid from the ground
    Patent number: 4571849
    Abstract: A machine for removing liquid from an area of ground over which the liquid has spread, comprises a convex hood (11) with a flat tray (12) mounted inside it. A motor driven fan (14) blows a downdraft out of the tray's central aperture (16) across the underside of the tray and into an annular gap (13) between the hood and the tray. The travelling air supports the machine above the ground and also lifts any ground-lying liquid into the annular gap and deposits it in a chamber inside the hood.
