Abstract

A reversible road scraper has two-edged blades that allow the scraper to be pulled in two different directions. The blades can be mounted on springs so that the scraper will not hang up on any objects that could potentially damage the scraper. Also, the scraper may include an edger blade to trim and define the edge of a road.

Claims

1. A reversible road scraper comprising:

a central beam comprising a first end and a second end with a connector at each end;

a first side beam disposed on one side of the central beam and substantially parallel thereto;

a plurality of blades each comprising two ends, the blades hingedly attached at each end to the central and first side beams, wherein each blade comprises two edges, one edge angled generally towards the first end of the central beam and the other edge angled generally towards the second end of the central beam; and

a variable adjustor connected to the central beam and to the plurality of blades.

2. The reversible road scraper described in claim 1, further comprising:

a second side beam disposed on the other side of the central beam from the first side beam and substantially parallel to the central beam;

a plurality of blades each comprising two ends, the blades hingedly attached at each end to the central and second side beams, wherein each blade comprises two edges, one edge angled generally towards the first end of the central beam and the other edge angled generally towards the second end of the central beam.

3. The reversible road scraper described in claim 2, further comprising springs that are adapted to connect each end of each blade to the central and side beams respectively, thereby enabling limited independent motion of each blade with respect to the beams.

4. The reversible road scraper described in claim 2, wherein one end of each of the side beams comprises an edger blade.

5. The reversible road scraper described in claim 1, further comprising springs that are adapted to connect each end of each blade to the central and side beam respectively, thereby enabling limited independent motion of each blade with respect to the beams.

6. The reversible road scraper described in claim 1, wherein one end of the side beam comprises an edger blade.

7. The reversible road scraper described in claim 1, further comprising a variable ballast.

8. A reversible road scraper comprising a frame comprising a first end and a second end and further comprising two beams;

a connector at each end of the frame; and

a plurality of blades comprising two ends, the blades attached at each end to the two beams, wherein each blade comprises two downwardly pointed edges, one edge angled generally towards the first end of the frame and the other edge angled generally towards the second end of the frame.

9. The reversible road scraper described in claim 8, wherein the blades are fixedly attached to the two beams.

10. The reversible road scraper described in claim 8, wherein the two beams are substantially parallel to each other.

11. The reversible road scraper described in claim 8, wherein one of the beams further comprises an edger blade.

12. The reversible road scraper described in claim 8, wherein the frame further comprises a variable ballast.

13. A reversible road scraper comprising:

a beam comprising first and second ends;

a connector at each end of the beam; and

a plurality of blades comprising two ends, the blades attached at one end to the beam, wherein each blade comprises two downwardly pointed edges, one edge angled generally towards the first end of the beam and the other edge angled generally towards the second end of the beam.

14. The reversible road scraper described in claim 13, wherein the blades are fixedly attached to the beam.

15. The reversible road scraper described in claim 13, further comprising a blade attached to each side of the beam.

16. The reversible road scraper described in claim 13, further comprising a variable ballast mounted on the beam.
