  • Patent number: 4290820
    Abstract: An improved front-end loader apparatus for collecting particulate material on a roadway surface comprising a frame assembly drivingly supported on the roadway, a windrow formation assembly supported at the forward end of the frame assembly for brushing particulate material into a windrow, and a feeder assembly disposed to engage the windrowed material up and onto a roadway scraper blade supported at the forward end of the frame assembly. An elevator assembly is disposed to receive the particulate material from the feeder assembly and elevate the material to a rear overhead discharge position. A residual material cleaning assembly is supported beneath the frame assembly and rearward to the feeder assembly for cleaning up residual material not collected by the feeder assembly, the residual material cleaning assembly directing the residual material to the elevator assembly so that the residual material is elevated to the rear overhead discharge position.

  • Patent number: 4213719
    Abstract: An improved portable grade averaging apparatus comprising an averaging bar assembly that serves as an elevation control reference for a track supported road working machine. One end of an averaging bar member is pivotally supported by a forward steering drive track assembly that serves as a forward walking beam, and the other end of the averaging bar member is pivotally supported by a rear track assembly that serves as a rear walking beam. A grade sensor assembly supported on one side by the road working machine contactingly engages the averaging bar member for directing the elevation of one side of the road working machine to establish the elevation of a working tool supported by the road working machine.

  • Patent number: 4140420
    Abstract: A portable grade averaging apparatus comprising an averaging bar assembly that serves as an elevation control reference for a track supported road working machine, one end of the averaging bar assembly being pivotally supported by a forward walking beam and the other end of the averaging bar being pivotally supported by a rear track assembly that serves as a track walking beam. A grade sensor assembly supported on one side by the road working machine contactingly engages the averaging bar assembly for directing the elevation of one side of the road working machine to establish the elevation of a working tool supported by the road working machine. A lifting bracket supported by the road working machine serves to lift the grade averaging apparatus into a grade clearing position while the machine is being maneuvered into a cutting position.
