Abstract

1435631 Earth-digging blades; excavator buckets POCLAlN SA 24 April 1974 [15 May 1973] 17828/74 Heading E1F A ground-penetrating working tool, e.g. an excavator bucket, has a blade provided with two projecting, toothed members 4 pivotal relative to the blade about axes 7 extending perpendicular to the plane of the blade, means 16 for coupling the members for synchronised pivotal movement in opposite directions and means 18 operable to cause said synchronised pivotal movement. Preferably the means 18 comprises a single driving element, e.g. a piston cylinder unit, coupled to the members 4 at points 19 lying on the same side of a plane containing the axes 7 and the means 16 comprises a rod of constant length pivotally coupled to the members 4 at two points 17 lying on opposite sides of said plane. The members 4 have tail portions 6 pivoted about bosses surrounding the axes 7 and pivotally connected. at -9 to the members 4, which have forked ends embracing the bosses about the axes 7. The parts 6, 16, 18 are positioned beneath a cover plate 22. Controlling the means 18 is a fluid circuit comprising a fluid reservoir, a main source 24 of pressurised fluid, and a two position distributor 23 controlled by a three position distributor 20 associated with an auxiliary source 39 of pressurised fluid.
