Abstract

822,362. Shovelling machines. WEATHERILL, F. Jan. 1, 1958 [Oct. 1, 1956], No. 25793/56. Class 68(1) The shovelling machine comprises a shovel 9 carried on an arm 1 and tiltable from a substantially horizontal shovelling position backwards to a load-carrying position and forwards to a discharge position by a control arm 7, there being separate hydraulic ram actuators 12 and 15 for the lifting and control arms. The arrangement is such that in the shovelting position the pistons of both actuators are fully retracted, and while the lifting arm 1 remains stationary the control arm is actuated to cause the shovel to tilt backwards and then to continue tilting to cause the shovel to remain in a satisfactory load-carrying position without spillage occurring as the lift arm 1 is raised and then cause forward tilting of the shovel to empty it when it has been raised to the required height
