ABSTRACT:
Apparatus useful in foundry moulding or casting embodying a turret having a lurality of arms rotatably mounted on and extending radially from a hub or drum rotatable about a vertical axis. The arms comprise a base, an inclined intermediate portion and an end portion parallel with the base. A fixed rack is disposed horizontally on the turret frame and extends along the arc of a circle in part of the zone swept by the arms during rotation of the hub. Each of the arms carries a pinion, whose teeth mesh with the teeth of the rack to induce rotation of each arm by 180.degree. to invert the mould or die carried on the end of the arm.
