Abstract

832,800. Shovelling machines. ANTHONYHOISTS Ltd. Feb. 17, 1958 [Feb. 21, 1957], No. 5936/57. Class 68(1) A control mechanism for ensuring that the scoop of an overthrow shovel attachment maintains a predetermined angle to the horizontal as it is swung up and over the supporting means by an arm or arms pivotably supporting the scoop and rotatably mounted on the supporting means for movement in a vertical plane. The scoop 11 is rotated relative to the arms 10 by an hydraulically actuated ram 16 of a servomotor system consisting of the jack 16, a valve 21, 27, and linkage 30, 31, 34, 35, the valve being operated by the linkage which causes the ram to maintain the scoop at the required angle to the horizontal as the linkage takes account of the swinging of the arms. The angle of the scoop to the horizontal can be varied by a hand lever 37 associated with the linkage by a link 36. The scoop may be replaced by other tools appropriate for association with the arms and control mechanism.
