  • Patent number: 7356949
    Abstract: A scraping device, a system and a method for collecting a material are provided. The scraping device may have a bowl having a first end and a second end. A lip may be positioned at the first end and may cover an opening at the first end. In an embodiment, direct mounted cylinders may be attached to the lip and may move the lip to completely cover or uncover the opening. The scraping device may have a tongue mounted to the bowl having a triangular-shaped plate mechanism that may be used to raise and to lower a cutting edge attached to the bowl. Cylinders connected to the mechanism may be retracted or extended to raise or to lower the scraping device. A load within the scraping device may be lifted by force exerted from a barrel end of a cylinder, thus utilizing a maximum potential of the cylinder.

  • Patent number: 6347670
    Abstract: An apparatus for modifying the earth's surface by removing soil from the surface, moving the soil to a new location and filling low areas. It comprises a frame carried by at least two wheels, a tongue mounted to the frame for attachment to a tractor, a cutting blade mounted on the frame, and a bucket pivotally mounted to the frame adjacent the blade to receive the soil cut by the blade. The wheels are pivotally mounted to the frame for movement of the wheels about the back wall and floor of the bucket between a first position and a second position. When the wheels are in the second position, a portion of each of the wheels underlies a portion of the floor of the bucket bringing the wheels closer to the center of gravity of the apparatus and its load.
