Abstract: A material collection device for particles received from a processing device on a road processing machine. The material collection device comprises a guide having a material discard opening and an attachment face. A conveyor support is shiftably fixed to the guide and is positionable in a substantially horizontal plane with respect to the attachment face. Additionally, the guide is positioned to direct particles milled from the road through the material discard opening to the conveyor support.

Abstract: A power crown adjustment apparatus for an asphalt screed includes first and second screed subassemblies movable with respect to each other, power apparatus for moving the subassemblies with respect to each other to alter the crown and control apparatus for automatically preventing the first and second screed subassemblies from moving beyond the predetermined range of movement.

Abstract: A mobile milling machine for milling a road surface includes a floating mold board for directing milled material onto a loading device positioned behind the machine. The mold board has fixed thereto a holder for the loading device. The loading device is pivotable side-to-side about a vertical axis, with respect to the holder. The mold board, the holder and the loading device are vertically movable a limited distance between a top and bottom stop position, and pivotable about a horizontal axis at the top stop position, to expose the milling roller for repairs. When the machine is in operation, the mold board, the holder and the loading device are hydraulically supported to permit the mold board to float along the milled surface in a grazing contact.

Abstract: A conveyor belt tensioning mechanism includes a frame assembly, a conveyor belt movable around a head and end pulley on the frame assembly, one of the pulleys being longitudinally movable along the frame assembly, a first adjustment member on the frame assembly for moving one end of the movable pulley longitudinally, to apply tension force to the belt, a second adjustment member on the frame assembly for moving the other end of the movable pulley longitudinally, to apply tension force to the belt, each adjustment member having an indicating member thereon, for indicating when tension force on the belt is within a preselected tension force range.
