Roadway patching attachment for dump trucks
First Claim
1. A roadway shoulder repair attachment for dump trucks having front and rear wheels, a roadway bulk material receiving dump bed and a chute leading downwardly from the dump bed between the front and rear wheels and substantially aligned with one of the rear wheels, for discharging the bulk roadway material from a discharge end thereof as the truck is moved forwardly;
- the attachment comprising;
a spreader blade;
means for positioning the spreader blade at an operative position adjacent the chute discharge end forward of the one rear wheel such that material discharged from the chute is received ahead of the spreader blade along the roadway, and so the spreader blade will grade the material to a prescribed level in relation to the roadway surface as the associated truck is moved forwardly and so the one rear wheel will roll over and compress the material graded by the spreader blade as the truck is moved forwardly.

Abstract
An attachment for dump trucks having a dump bed with a chute leading downwardly to a discharge end for discharging material along a roadway surface. The attachment adapts the truck to perform roadway surface repairs by receiving, grading, and pressing roadway repair material into place along damaged areas of the roadway surface while the truck is driven forwardly. The attachment includes a blade that is pivoted to the truck at a position rearwardly adjacent the chute discharge end. The blade is arched to receive and grade loose bulk repair material delivered from the dump truck bin through the downwardly projecting chute. The blade is also pivoted between an operative position, riding along the roadway surface, and an inoperative position above the roadway surface. Material delivered to the blade and graded thereby can be compacted and pressed into damaged roadway areas by the supporting truck tires.
