ABSTRACT:
An individual section of a multiple section glassware forming machine is shown wherein each such section preferably includes three stations performing separate and sequential operations in forming articles of glassware. Each such section may be adapted for "single gob" or "multiple gob" use whereby each station in the section performs its operation in forming either a single article of glassware or multiple articles at the same time. The section shown is adapted for "double gob" operation. Its first station is utilized in forming (by overhead pressing plungers) two parisons in upright parison molds. Its second station is utilized to further form the parisons either in intermediate blow molds or by suspending the parisons for a re-heat. Its third station is utilized to blow the parisons into the final shape of the glassware article being made. The stations are spaced along the longitudinal center line of the machine section, and a transfer mechanism is provided which includes a reciprocating carriage for supporting and moving the parisons and the finally shaped articles along, substantially horizontally, from station to station and onto a deadplate in sequence. After reaching the deadplate, the finally shaped articles are moved onto a conveyor by means of mechanism not a part of this invention.
