发明名称 Combined spreading and sifting device for leveling soil
摘要 The leveling device includes a panel of expanded metal that is maintained in a planar or flat condition by means of a plurality of laterally spaced fins, the expanded metal being welded to the lower edges of the fins. Welded to the upper edges of the fins and extending transversely thereacross are two rods to which is centrally secured an angle member or bracket. One flange portion of the angle member has welded thereto the lower end of a tubular handle. A combined spreading and sifting action is derived by moving the device back and forth across the soil to be leveled, some of the material being scooped onto the upper side of the panel between the various fins where it remains if too large to be sifted downwardly through the diamond-shaped openings in the panel of expanded metal.
