Abstract
Glassware forming apparatus includes a first arm for supporting a first neck ring and a second arm for supporting a first blow head. The first and second arms are supported from a vertical column for projection along its axis and for independent pivotal movement about the axis. The apparatus also includes a parison mold and two blow molds. Each of the blow molds is divided into two portions, the portions of each mold being joined at a hinge. The axis of each hinge extends generally parallel to the column axis. Apparatus is provided for opening and closing the molds, and for pivoting and projecting the first and second arms to convey glassware blanks supported by the neck ring alternately to the two blow molds from the parison mold, and to move the blow head between the two blow molds to blow the glassware blanks into articles of glassware. The illustrated apparatus for pivoting and projecting each of the arms along the common axis includes a pinion gear attached to a shaft, the other end of which is attached to one of the arms. First and second racks alternately engage the pinion gear. A frame supports the racks for selective shifting movement. The frame itself is supported for movement longitudinally of the racks to turn the pinion gear when one or the other of the racks is in engagement with the pinion gear. Piston-and-cylinder arrangements are provided for longitudinally controllably moving the frame support apparatus and for controllably shifting the frame selectively to engage the pinion gear with one of the first and second racks. The frame is preferably pivotally mounted on the frame support and has a first position in which the first rack engages the pinion gear and a second position in which the second rack engages the pinion gear. The method of the present invention comprises the steps of forming blanks in the parison mold and alternately depositing the blanks in the blow molds to be formed into glassware.
