Abstract

1,004,162. Shovelling machines. DOWTY HYDRAULIC UNITS Ltd. Aug. 19, 1964 [Aug. 22, 1963], No. 33300/63. Heading E1F. For causing a digging implement 17 mounted on an arm 14 pivoted on a boom 11 to follow a predetermined excavating path there is associated with the arm and the boom control means comprising a pair of links 50, 51 so pivotally connected together and to the boom and the arm as to form therewith a parallelogram linkage, the pivot 54 connecting the two links being constrained to follow a predetermined path shaped in accordance with said excavating path and so applying feed back to the control valves 30, 40 of rams 19, 23 actuating the boom and arm. The spools of the valves of the spool and sleeve type have each a slot extension, 55, 57 the two extensions determining the path of movement of the pivot 54.
