  • Patent number: 4536124
    Abstract: A revolving-ladle turret having a turret member furnished with a pair of ladle-carrying arms, mounted on a platform which rotates about a vertical axis. The turret member is supported by a pair of articulated linkages similar to parallelograms of the double-handle type. The upper or bridge sides of the parallelograms are horizontal and rigidly supported by the platform and extend parallel to the ladle-carrying arms. These parallelograms have their respective handles shaped at right angles and are linked to the turret member in positions which are symmetrical to it about the axis of rotation of the platform. The articulated parallelograms fundamentally constitute synchronizing devices for the displacements of all of the points of the turret member and of the attached ladle-carrying arms.
