  • Method of and apparatus for picking up refuse from a surface, such as a track bed
    Patent number: 4570287
    Abstract: To clean the ballast bed of a railroad track, a wheeled vehicle movable over the ballast bed contains a blower for generating a positive flow of air and a suction flow. A suction port is located on the vehicle spaced a given distance above the ballast bed. A pipe section outlet is located around the suction port. The positive flow of air is directed through the pipe section outlet so that it provides a circular air flow about the downward projection of the suction port. The circular air flow sweeps the surface of the ballast bed and any refuse swept up is drawn into the suction port by the suction flow generated by the blower.
