Glassware forming machine

Abstract

This invention relates to a glassware forming machine of the type comprising a pair of carriers each pivoted on a first generally vertical axis for swinging movement toward and away from each other between an open position and a closed position, and a set of at least three mold members carried by each carrier, each mold member on each carrier being related to a mold member on the other carrier so that, with the carriers in their closed position, each mold member on one carrier mates with a mold member on the other carrier to define a mold cavity for molding an item of glass. The improvement involves a holding assembly on each carrier for holding a respective set of mold members. This holding assembly includes a first holder which is pivoted on a respective carrier for holding one or more mold members of the set for pivotal movement relative to the carrier on a second vertical axis, and a second holder pivoted on the first holder for holding the remaining mold members of the set for pivotal movement on a third vertical axis relative to the first holder and the one or more mold members held thereby. The arrangement is such that, as the carriers swing to their closed position and respective mold members move into mating relationship, the first and second holders of said holding assemblies and the mold members held thereby pivot about their respective second and third axes to final positions wherein substantially the same closing pressure is applied to each pair of mating mold members.
