Abstract
An apparatus for hauling, spreading and compacting asphalt, gravel and like aggregates is a so-called belly-dump or bottom dump trailer with mechanisms for single pass delivery and compaction of aggregates to form road shoulders and the like.
Claims11
A device for spreading spreadable material from a vehicle, wherein said vehicle has a bin for holding said spreadable material and said bin has a lower aperture therein for gravity feeding therethrough of said spreadable material, and wherein said vehicle has a longitudinal axis corresponding to a direction of forward motion of said vehicle, said device comprising:
- when said device is mounted to said vehicle, delivery means co-operating with said lower aperture for unloading, delivery and dispensing said spreadable material selectively on either a first lateral side of said vehicle or on an opposite second lateral side of said vehicle said dispensing on either said first or second lateral sides of said vehicle at a first lateral distance selectively spaced laterally outwardly of said vehicle,
- a selectively inclinable blade, selectively laterally translatable a second lateral distance corresponding to said first lateral distance, said selectively inclinable blade selectively laterally translatable on mounting and translation means mountable to said vehicle, said blade mountable generally perpendicular to said longitudinal axis, said mounting and translation means when mounted to said vehicle for selectively laterally outwardly translating said blade outward of either of said first or second lateral sides corresponding to said first or second lateral sides on which said spreadable material is dispensed by said delivery means, selective inclination means for selectively inclining said blade relative to a ground surface adjacent said vehicle, elevating and lowering means co-operating with said mounting and translation means for elevating and lowering said selectively inclinable blade into proximity to, at a generally constant elevation above, said ground surface in response to lateral translation of said inclinable blade when said inclinable blade is inclined from horizontal while said vehicle is translating in said direction of forward motion.

- wherein said selectively inclinable blade has pivotally mounted at an end thereof a second blade member selectively pivotable about a generally vertical axis of rotation between an end cap position generally perpendicular to said selectively inclinable blade so as to extend forwardly of said selectively inclinable blade in said direction of forward motion, and pivotable from said end cap position to a slope trimmer position generally co-planar with said blade.
