  • Patent number: 5732993
    Abstract: The present invention discloses a method of constructing collapsible raw material bins for a portable asphalt plant in such a manner that said raw material bins may be located on the same flatbed semi trailer as the rest of the asphalt plant. The collapsible material bins are constructed in such that, when not in use, they may collapse in an accordion-like fashion upon one another. This is done by having one wall of two of the bins constructed so that it may slide in and out within the respective bin. Additionally, the bins themselves are mounted on a sliding rail system which allows for the necessary movement of the bin walls. The end result of this design is that it provides a compact enough raw material bin system to allow it to be constructed on the same flatbed trailer as the asphalt tumbler, and yet provides a large enough raw material bin capacity to allow for the efficient operation of the portable asphalt plant.

  • Patent number: 5316430
    Abstract: A waste hauling apparatus including a truck body divided into two separate compartments by a movable dividing wall. A bucket assembly having separate side-by-side bins is operative to transfer trash material loaded into the bucket by an operator at ground level to the isolated compartments. The bucket travels between a material receiving position and a material discharging position along a trackway having a path of movement including a vertical portion and a transverse portion. At the material discharging position the material contained in the bins is discharged into associated material receiving openings that communicate with respective compartments defined by the truck body. The bucket is reciprocally conveyed between the trash receiving and trash discharging positions by a chain drive mechanism driven by a fluid pressure operated motor and interconnected with the bucket by a linkage mechanism. The linkage mechanism cooperates with the chains to define the limits of movement for the bucket.
