Abstract

930,192. Shovelling machines. PENN INVENTIONS Ltd. April 25, 1962 [March 6, 1961], No. 8095/61. Class 68 (1). In a shovelling machine there is provided a fastening means 12, 13 for temporarily coupling a scoop 7 to the supporting arms 8 at the completion of the swinging of the scoop about the pivotal connection thereof with the arms 8 by a motor 11 operating in one direction so that when the operative direction of the motor is then reversed upward movement of the arms will then occur. Preferably the motor is a double-acting hydraulic ram 11 pivotally like the arms 8 both to the scoop 7 and to a mobile chassis 1. The latch 12 of the fastening means 11, 12 can like that of the discharge door of the scoop be freed from the operator's positioning by tensioning a control cable such as 20.
