Abstract

A road scraper includes a frame having forwardly positioned blades extending rearwardly and laterally for directing loose material against a rear blade extending angularly in the opposite direction between rearwardly extending side frame members thereby causing loose material on the road to be redistributed across the road under the rear blade on the back side of the frame. A rearwardly positioned dam blade cooperates with the rear angular blade to cause loose material to be accumulated and then discharged through a passageway between the rear end of the dam blade and the angular blade.

Claims

1. A vehicle drawn road scraper comprising,

a frame having a forward laterally extending frame member with substantially parallel oppositely positioned unequal in length side frame members interconnected at their rear ends by an angularly extending frame member which extends from the shorter side frame member rearwardly and laterally towards the longer side frame member,

a plurality of angularly and forwardly positioned ground engaging blades extending angularly from the longer side frame member rearwardly and laterally towards the shorter side frame member and said angular rear frame member, and

a ground engaging rear blade on said angular rear frame member whereby ground material loosened by said angularly and forwardly positioned blades includes large and small pieces which are moved into engagement with said rear blade on said angular rear frame member with small pieces moving under said rear blade on said angular rear frame and larger pieces being moved angularly along said rear blade on said angular rear frame and being further reduced in size such that loose ground material is redistributed onto the road surface.

2. The road scraper of claim 1 and a dam blade is positioned rearwardly of said plurality of angularly positioned blades and between said longer side frame member and said rear blade on said angularly extending rear member, said dam blade terminating rearwardly in spaced relationship to said rear angular blade thereby creating a passageway therebetween for loose material boiling up between said rear angular blade and said dam blade being partially discharged through said passageway.

3. The road scraper of claim 1 and adjustable transport and blade depth control wheels are provided on said frame.

4. The road scraper of claim 1 wherein said frame includes a pivotal wing section which includes the shorter side frame member.

5. The road scraper of claim 1 wherein said frame includes a dam blade having a rear end spaced from said rear blade on said angularly extending rear frame member whereby loosened ground material be accumulated between said rear blade and dam blade and may flow through said space and rearwardly and laterally along said rear blade on said angularly extending rear frame member.

6. The road scraper of claim 5 wherein an additional angularly and forwardly positioned blade is provided extending in a direction approximately ninety degrees from said first mentioned angularly forwardly positioned ground engaging blades to direct ground material rearwardly along the longitudinal center line of said frame.

7. The road scraper of claim 1 and an elongated magnet is laterally positioned on said frame closely spaced from the ground to pick up metal items on the road.

8. The road scraper of claim 1 wherein said shorter side frame member includes a blade extending along its substantial length.

9. The road scraper of claim 8 wherein said blade on said shorter side frame member is angled rearward and laterally towards the forward end of said rear blade on said angular rear frame member.
