A glassware forming machine has at least three individual side-by-side molds at both the blow and the blank side of the machine, which molds are upwardly open and adapted to be closed by a blowhead or baffle depending upon which side of the machine (blank or blow) that the molds are at, that is for either forming the final article at the blow side or the preliminary parison at the blank side. Three blowheads are disclosed for use at the blow side of a machine, and are retained in a carrier arm for limited vertical movement in order to accommodate variations in height of the tops of the individual molds. Two links extend laterally through slots in the blowhead retainers, and a bellcrank lever interconnects these links to the carrier itself so that upon closing contact made between one of the three blowheads and its associated mold, downward movement of the other two blowheads will occur thereby equalizing the closing forces between all three blowheads and their associated molds.
In a glassware forming machine having at least one section including three side-by-side upwardly open molds which are closed by mold closing heads, a carrier adapted for movement toward and away from the upwardly open side-by-side molds, and three mold closing head retainers mounted in said carrier the improvement comprising:
