Abstract
1276537 Earth-working machines POCLAIN 24 July 1969 [2 Aug 1968] 37250/69 Heading E1F A tool 35 of an earth-working machine is supported from a turret 31 by a system of arms which can define two parallelograms 13, 14, 28, 19 and 21, 22, 27, 26 with side 13, 19 of one parallelogram equal to side 22, 27 of the other parallelogram so that when rams 5, 12 are operated simultaneously the parallelograms are deformed and the tool 35 can be moved along a straight line at an angle determined by the angle of jib arm 1 and at a height determined by parallel linkage 4, 6, 7, 8. In the embodiment shown the two parallelograms can be maintained as such by rams 5a and 12a operated simultaneously with rams 5 and 12. Alternatively rams 5a and 12a can be replaced by arms extending between points 14 and 28, and 21 and 26 with arm 8 extending between points 27 and 26. The height adjusting linkage can be positioned as shown or between parallelogram 21, 22, 26, 27 and tool 35 which may be a drag or loader bucket. The rams 5, 12, and 5a and 12a if present, may be fed in series.
