  • Automatic piston pouring equipment
    Patent number: 3979033
    Abstract: An automated ladle, based on a swinging arm concept for pouring piston castings. The ladle carried at the end of the arm, is tilted in a controlled and programmed manner to a "pour position" by means of a cam switch operated motor drive which rotates the swinging arm about its longitudinal axis to effect pouring. Electrical circuitry interconnects the ladle mechanism with a molten metal holding furnace and a pair of automated piston molding machines for automatically controlling the operation of the entire assembly.
