Road repair machine

Claim 2

A road repair machine comprising a wheeled vehicle, a heating hood assembly mounted at the rearward end of said vehicle, means for adjustably mounting said assembly on said vehicle in a manner such that said assembly can be placed at various heights above an approximately horizontal surface on which the wheels of said vehicle are resting, said vehicle having a hot-mix hopper thereon, said hopper having an entrance opening into which the material for a hot mix can be inserted, said hopper having exit opening means on at least one side of said vehicle and disposed at a convenient height so that a workman standing on said surface can insert a shovel into said exit opening means and withdraw hot-mix material, fuel tanks mounted on said vehicle, means interconnecting said fuel tanks and said heating hood assembly.

Claim 3

The combination of claim 1 in which said means for attaching said heating hood assembly to said vehicle comprises right and left linkage means disposed on the right and left sides of said vehicle respectively and extending forwardly from said heating hood assembly, pivotal connection means at the forward and rearward ends respectively of each of said linkage means, means connecting the pivotal connection means at the rearward ends of each linkage means to said heating hood assembly in a manner for the pivoting of the forward end of said heating hood assembly about a horizontal first axis extending from the right to the left of said vehicle, means connecting the respective pivotal connection means at the forward ends of said linkages to said vehicle in a manner for the pivoting of the forward ends of said linkage means about a second horizontal axis extending parallel to said first horizontal axis, at least one elongated hydraulic cylinder assembly means extending forwardly and rearwardly of said vehicle and having a rearward end disposed above said heating hood assembly, means pivotally connecting the rearward end of said hydraulic cylinder assembly to said heating hood assembly in a manner for rotation about a third axis parallel to said first axis, said hood assembly having heating elements, the lowermost parts of said heating elements being disposed approximately in a plane, means pivotally connecting the forward end of said hydraulic cylinder assembly means to said vehicle in a manner for the pivoting of the forward end of said hydraulic cylinder assembly means about a fourth axis parallel to said first axis, said fourth axis being so disposed that when said heating hood assembly is disposed in operational road-heating positions closer to said supporting surface then operation of said hydraulic cylinder assembly means will cause movements of said heating hOod assembly which dispose the said plane of said lowermost parts in substantially a horizontal position.

Claim 4

The combination of claim 2 in which said axes are also in positions such that when said hydraulic cylinder means is shortened to a maximum, the rearward end of said hood assembly will be substantially higher than its forward end.

Claim 5

The combination of claim 1 in which a hoist is mounted on said truck.

Claim 6

The combination of claim 1 in which a debris container is mounted on said truck.

Claim 7

The machine of claim 1 in which said truck has a bed having a substantially horizontal upper surface, said hot-mix hopper having bottom wall means which inclines downwardly at one of the sides of said vehicle, outermost parts of said bottom wall means projecting beyond the adjacent side of said bed and projecting below the adjacent side of said bed, said hot-mix hopper exit opening means being disposed at substantially the same height as the outermost portion of said bottom wall means so that said opening is disposed lower than the upper side of said bed so that a workman can insert a shovel into it with ease.

Claim 8

The combination of claim 1 in which a door means is mounted on the outside of said hopper and covering said opening means, means for mounting said door means on said hopper in a manner for the vertical sliding of said door means upwardly on the outside of said hopper for access to and closing said opening means.
