Abstract
A discharge chute is arranged for pivotally mounting an abutment plate at a distal end of the chute to prevent further spillage and flow of concrete through the chute. The abutment plate may be hingedly mounted about a first end thereof or pivotally mounted about a plurality of spaced rods that are mounted to top edges of the chute.

A concrete chute apparatus, comprising in combination,
- a concrete discharge chute, the chute including a distal end surface, and the chute oriented about a chute axis, wherein the chute is of a generally semi-cylindrical configuration and includes a chute first edge spaced from and parallel a chute second edge, with the distal end surface orthogonally oriented relative to the chute axis, and
- the chute including a concave interior surface, and
- an abutment plate, the abutment plate including hinge means mounted to the chute first edge for pivotment of the abutment plate relative to and in an orthogonal orientation to the chute axis.
