Vibratory roller with axially spaced zig zag impact bars and wire rope cleaners

In combination with a vibratory roller journalled from a frame portion of a vehicle of the compaction-type, said roller including a generally cylindrical outer face, a plurality of circumferentially extending lug bands carried by the outer face of said roller, said lug bands being disposed in laterally spaced zones of said outer face spaced longitudinally of said roller and in which diametric planes of said roller lie, said lug bands being comprised of lugs including outer surfaces disposed at least substantially normal to intersecting radii of said roller and generated about the axis of rotation of said roller, said outer surfaces being at least substantially circumferentially continuous about said roller and extending in zig-zag paths contained in said zones, the lateral spacing between said zones defining circumferentially continuous paths of said outer face free of said lug bands, scraper members carried by said frame portion and disposed in at least closely spaced relation relative to said face, said scraper members being operative to scrape accumulated debris from said paths as said roller is rotated relative to said frame portion, said scraper member comprising short twisted multi-strand wire rope members disposed generally radially of said roller, said lugs including opposite side surfaces divergent from said outer surfaces toward said outer face, said side surfaces being inclined generally 60.degree. relative to said outer surfaces, said lugs being hexagonal in transverse cross section and welded to said outer face with the welding operation being performed to create fillets on opposite sides of said lugs forming inward continuations of said inclined side surfaces.
