ABSTRACT:
A concrete chute apparatus for preventing the accidental discharge of cement residue from the chute of a cement truck while the truck is moving is disclosed. To attain this, an abutment plate obstructs the opening of a cement truck caused by the folding of an articulated chute. In an embodiment, an abutment plate is rigidly affixed to an over-chute section of the articulated chute such that the plate obscures the concrete path when the over-chute section is rotated to the up position.
