Abstract

944,786. Shovelling machines; earth graders. ETABLISSEMENTS F. POTAIN & CIE S.A. July 20, 1962 [Aug. 3, 1961], No. 27960/62. Heading E1F. To ensure of substantially horizontal movement of a tool, e.g. bucket, scoop 12 or grader, during the major portion of the traverse of the tool in contact with earth by a ram 9 acting between a vertically swingable boom 5 and a tool-carrying arm 8 pivotally mounted at 7 on the boom the ram 6 for vertically swinging the boom is so connected to the boom and to the arm that as the arm swings relatively to the boom the boom swings vertically to cause the tool to appropriately rise or fall as necessary for horizontal movement thereof. A transversely extending stud 6a on the piston rod of the ram 6 may slide in an elongated opening 16 in the boom 5, or be connected to a lever pivotally dependent from the boom, or to one arm of a two arm lever pivoted on the boom whilst a rod 17 of fixed length is pivotally connected between the arm 8 and the stud 6a or to the other arm of the two arm lever.
