Abstract

1291227 Earth-digging tool DEFENCE SECRETARY OF STATE FOR 19 Jan 1970 [28 Oct 1968] 51047/68 Heading E1F Mounted on the leading edge 4 of an earthworking tool, e.g. an excavator bucket, of an earth-moving machine are two earth-contacting members 1, 2 that are disposed symmetrically of the centre line of the edge and are, in use of the tool, reciprocated in opposition in directions parallel to the edge. Each member may have a serrated forward surface and may be resiliently mounted, preferably by bonding elastic material, on the leading edge of the tool. Reciprocation of the members may be caused by hydraulic linear actuators, a rotary drive coupled to a scotch yoke or to a cam, or by wave transmission through a hydraulic medium in a long pipe.
