Abstract

An improved asphalt patching machine which is mountable to a motor vehicle having a supply of asphalt patch material thereon. The patching machine comprises a dispensing and finishing assembly fed by a multi-part, articulatable conveyor which feeds asphalt patching material to the dispensing and finishing assembly, which is movable in substantially the plane of the roadway, to position the dispensing and finishing assembly over the effected area to be patched. The machine first deposits patching material in the effected area and, thereafter, from the dispensing and finishing assembly, integrates the patch into the existing surrounding roadway.

Claims

1. An asphalt patching machine for delivering and finishing asphalt material in an effected area of a roadway, said asphalt patching machine being attachable to a vehicle having a supply of patching material stored thereon;

said patching machine having a dispensing and finishing assembly for depositing and finishing patching material from the vehicle to the effected area of roadway;

a conveyor system disposed between the supply of patching material and said dispensing and finishing assembly;

said conveyor system having at least two conveyor sections, said conveyor sections being connected to one another and the vehicle so as to be rotatable relative to one another and the vehicle in a plane substantially parallel to the roadway;

said dispensing and finishing assembly being attached to said conveyor, and including a receiving element;

a delivery element; and

a tamper, said tamper being telescopingly received about an end of said receiving element,

said tamper being mounted about a delivery sleeve, a transfer shaft extending through said tamper and said delivery sleeve, eccentrics disposed on said shaft such that rotation of said shaft will cause said tamper to reciprocate to tamp down material delivered to the effected area,

said conveyor delivering patching material to said receiving element where it drops to the effected area, said tamper being reciprocable to tamp down and finish the material so deposited, and movable over the effected area.

2. The asphalt patching machine of claim 1, wherein bearings are interposed between each said conveyor section and between said conveyor section and said supply of said patching material to facilitate relative rotation of said conveyor sections.

3. The asphalt patching machine of claim 1, wherein each said conveyor section has a separate conveyor, said conveyors delivering material from said supply of patching material to said dispensing and finishing assembly.

6. The asphalt patching machine of claim 1, wherein bars are secured to said receiving element, said bars being manually manipulateable to move said dispensing and finishing assembly into and about the effected area of a roadway, and a control panel disposed in close proximity to said bars, said control panel permitting operation of the various driving elements which move a supply of patching material to the effected area and tamp the material so delivered to patch the effected area.

7. The asphalt patching machine of claim 1, wherein a strap is secured between said delivery element and said tamper, said strap being adjustable to control the stroke of said tamper, and causing said tamper to work across the path.

8. The asphalt patching machine of claim 7, wherein the relative position of said strap between said delivery element and said tamper being adjustable.

9. The asphalt patching machine of claim 8, wherein said bars permitting movement of said patching machine in a generally parallel direction relative to said roadway.

10. The asphalt patching machine of claim 7, said strap being vertically disposed along one side of said delivery sleeve and said tamper, whereby operation of said tamper causes said dispensing and finishing assembly to move across the surface of the said patching material so deposited.

11. The asphalt patching machine of claim 1, wherein said patching machine is generally collapsible to a transport position adjacent the vehicle.

5. (canceled)

12. An asphalt patching machine for delivering and finishing asphalt material in an effected area of a roadway, said asphalt patching machine being attachable to a vehicle having a supply of patching material stored thereon;

said patching machine having a dispensing and finishing assembly for depositing and finishing patching material from the vehicle to the effected area of roadway;

a conveyor system disposed between the supply of patching material and said dispensing and finishing assembly;

said conveyor system having at least two conveyor sections, said conveyor sections being connected to one another and the vehicle so as to be rotatable relative to one another and the vehicle in a plane substantially parallel to the roadway;

said dispensing and finishing assembly being attached to said conveyor, and including a delivery sleeve and a tamper telescopingly received thereabout, a transfer shaft extending through said tamper and said delivery sleeve, eccentrics disposed on said shaft such that rotation of said shaft will cause said tamper to reciprocate to tamp down material delivered to the effected area;

a roller;

said roller attached to said delivery and finishing assembly;

said roller being movable over the patching material to finish the patch.

13. The asphalt patching machine of claim 12, wherein a platform is provided disposed above said roller whereby an operator may ride as the roller is moved across the effected area to finish said patch.

14. The asphalt patching machine of claim 12, wherein bearings are interposed between each said conveyor section and between said conveyor section and said supply of said patching material to facilitate relative rotation of said conveyor sections.

15. The asphalt patching machine of claim 12, wherein each said conveyor section has a separate conveyor, said conveyors delivering material from said supply of patching material to said dispensing and finishing assembly.

16. The asphalt patching machine of claim 12, wherein said dispensing and finishing assembly comprises a series of elements, said elements being telescopingly received in one another and comprising a receiving element for receiving material from said conveyor, a delivery sleeve for delivering material to the effected area, and a roller, said delivery sleeve being telescopingly received about said receiving element, and said roller being mounted adjacent the free end of said delivery sleeve for tamping down material delivered to the effected area.

17. The asphalt patching machine of claim 12, wherein bars are secured to said receiving element, said bars being manually manipulateable to move said dispensing and finishing assembly into and about the effected area of a roadway, and a control panel disposed in close proximity to said bars, said control panel permitting operation of the various driving elements which move a supply of patching material to the effected area and roll the material so delivered to patch the effected area.

18. The asphalt patching machine of claim 12, wherein said patching machine is generally collapsible to a transport position adjacent the vehicle.

20. The asphalt patching machine of claim 12, wherein bars are secured to said receiving element, said bars being manually manipulateable to move said dispensing and finishing assembly into and about the effected area of a roadway, and a control panel disposed in close proximity to said bars, said control panel permitting operation of the various driving elements which move a supply of patching material to the effected area and finish the material so delivered to patch the effected area.
