Abstract

1437605 Excavator buckets GREAT CANADIAN OIL SANDS Ltd 15 June 1973 [15 June 1972] 28598/73 Heading E1F For securing to the leading edges of an excavator bucket is a U-shaped, digging lip structure having transversely spaced and generally longitudinally extending digger teethreceiving sockets mounted on the base and sides of its forward digging edge of which the central portion of the base is rearwardly displaced relative to the junctions of the base and the sides of the digging edge. Preferably the central portion is symmetrically displaced rearwardly, e.g. in a stepped configuration 13a-13f with a tooth-receiving socket being then provided at each step. Mounting of identical digger teeth in the sockets of such a lip structure will result in material being first engaged by teeth at the corners of the structure. Specifications 1437606, 1437607/75 and 962645 are referred to.
