  • Patent number: 4445247
    Abstract: An apparatus for removing water from a substantially flat ground surface is comprised of a rolling carriage carrying a horizontally disposed collecting vessel enveloped by a perforated rigid cylindrical drum that supports a resilient absorbent material. The drum is adapted to rotate about the collecting vessel. At the lower extremity of the drum, the absorbent material takes up water. At the upper extremity of the drum, a squeeze roll acting against the drum expresses water from the absorbent material. The expressed water falls into the collecting vessel. A handle is pivotably associated with the carriage. When in its lowermost position, the handle causes disengagement of the squeeze roll from the drum.
