Abstract

1,182,710. Earth working machines. POC LAIN. 29 Nov., 1967 [26 Jan., 1967], No. 54248/67. Heading E1F. An earth working machine is adapted to have a grab substituted for a drag bucket or shovel, the grab when used being attached at 9 to one arm of a lever 8 which is pivoted at 2 to a beam 1 at the same position at which the bucket or shovel was pivoted, the other arm of the lever 8 being adjustably connected at 7 to a lever 3 pivoted on the beam 1 and previously used to interconnect the bucket or shovel and hydraulic ram 5. The lever 8 is held from moving pivotally by the ram 5 and lever 3 and prevents movement of the latter. It is stated to be known to support a substituted grab from the end of an arm pinned at 2 to the beam 1, the arm and the end of the beam having interengaging surfaces to prevent the arm pivoting, Fig. 2 (not shown).
