Abstract
An invert/neckring mechanism for an individual section (I.S.) glass forming machine including a rectangular shaft and a pair of neckring arm holders having a central passage which mates with the rectangular cross-sectional shaft to limit the movement between the shaft and the arm holders to axial movement all rotated through the invert arc by a hydraulic actuator in juxtaposition therewith. A plurality of springs bias the arm holders together to a closed position and a hydraulic double piston cylinder assembly is mounted adjacent to the shaft between the arm holders to open and close the arm holders.
