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.
Claims16
An apparatus which prevents the unintentional escape of cement from a cement truck comprising:
- a main chute;
- an over-chute hingeably connected to the main chute, the hinged connection of the over-chute to the main chute being such that the over-chute can be positioned to rest on top of the main chute and the hinged connection being such that the over-chute can be folded down from this resting position so that the main chute and over-chute section form an elongated chute through which cement can be poured;
- and
- an abutment plate connected to the over-chute such that when the over-chute is positioned to rest on the main chute, the abutment plate is positioned within the main chute so as to block material from the main chute, and when the over-chute is folded down, the abutment plate is positioned above the main chute and the over-chute.
1 more element
A concrete chute apparatus, comprising:
- a concrete discharge chute, wherein the chute is oriented about a chute axis, wherein the chute is of a substantially semi-cylindrical configuration and includes a chute first edge spaced from and parallel to a chute second edge, wherein the chute has a concave interior surface, and wherein the chute comprises an over-chute section, wherein the over-chute section includes a proximal end surface and a distal end surface, and wherein the end surfaces are orthogonally oriented relative to the chute axis, and
- an abutment plate, wherein the abutment plate includes a mounting means affixed to the over-chute section first edge, which mounting means holds the abutment plate station immobile relative to the over-chute section and in an orthogonal orientation to the chute axis.
