Abstract:
Apparatus for use in conjunction with a dump-truck;the dump-truck being of the kind having a hopper for containing road-repair-materials, and a side-chute for discharging said materials, the side-chute being located at the side of the truck, and ahead of the rear wheels, wherein:the apparatus comprises a means for laying a stripe of the repair material on the road surface, the stripe being positioned in line with a rear wheel of the truck, whereby the rear wheel rolls over the stripe, and compacts the material;the apparatus includes a box, for containing the road-repair-material;the apparatus includes a means for mounting and positioning the box on the truck under the side-chute, for receiving material from the side-chute;the apparatus includes a laterally-extending stripe-thickness-setting blade;the apparatus includes left and right side-runners, which are positioned in the apparatus adjacent to the left and right lateral ends of the blade, respectively;in the apparatus, the side-runners comprise a means for supporting the weight of the box;the apparatus includes a means for holding the stripe-thickness-setting-blade a height H clear of the road surface;the box has a floor-surface, being the upward-facing surface against which rests the weight of the repair-material in the box;the box is provided with a deposition-aperture, which is arranged in the apparatus for discharging material therethrough from the box onto the road surface;the deposition-aperture occupies only a minor proportion of the floor-surface of the box, whereby most of the weight of the repair-material in the box acts on the box, weighting the box against the road surface;in the apparatus, the deposition-aperture is positioned ahead of the blade, and the apparatus is so arranged that the blade passes over the material deposited from the aperture, and the thickness of the deposited stripe is defined by the height H at which the blade is held above the road surface.
