Abstract:
    A parison mold portion (20) of a glassware forming machine and a parison plunger (240), is provided with means for cooling the parison plunger. The means for cooling the parison plunger includes a central cooling passage (258) that communicates with an end surface (246) and that extends longitudinally toward a nose (254), and a plurality of umbrella passages (162) that communicate with the end surface (246) radially outward from the central cooling passage, that are circumferentially spaced, and that intercept the central cooling passage proximal to the nose. A tube (264) is inserted into the central cooling passage, is longitudinally adjustable, and is effective to adjustably determine the longitudinal position wherein the umbrella passages communicate with the central cooling passage; whereby cooling of portions of the parison plunger proximal to the nose versus portions distal from the nose, is selectively controlled.
