Abstract: A press for molding and blowing hollow articles includes plural mold halves disposed in a table at successive work stations about an axis, a platen carrying complimentary mold halves movable toward and away from the table, and a tool carrier journaled in that axis, reciprocatable with the platen and rotatable to index the tools from one station to another. A first collar journaled in the table about the shaft is rotatable for indexing purposes, and a second collar coupled to the shaft is provided for rotational engagement with the first collar to accept torque from the first collar while the mold halves are open, subject to manual disengagement of the collars by shift of the second collar axially of the shaft.
