Abstract
1,087,663. Shovelling machines. GIOVANNETTI MIACCHINE S.p.A. Dec. 30, 1964 [Dec. 31, 1963], No. 52909/64. Heading E1F. A feed back device for controlling tilting of the shovel with relation to angular displacement of vertically swingable support arms thereof is associated with the rotary vane type actuator for controlling movement of the shovel relative to the jack-actuated arms and for mounting the shovel on the arms. A chain drive from the pivotal axis of the shovel to the pivotal axis of the boom is actuated by relative movements between the shovel and the arms and the arms and the support thereof to appropriately operate means to supply pressurised fluid to the actuator to maintain the angularity of the shovel to a fixed datum plane as the arms are swung up and down.
