Abstract: A neck ring guide for aligning neck ring sections in a glassware forming machine has a center body and a pair of spaced parallel runners coupled to the center body for receipt in guide slots in the neck ring sections. Keepers on the outboard sides of the runners retain the runners in the guide slots. Instead of keepers, the runners may be retained in the guide slots by roll pins on the neck ring sections engaged in retainer slots in the runners.

Abstract: An H-28 machine has a plurality of identical sections each processing a gob of molten glass into a parison and then into a piece of ware each complete revolution of the section. Each section includes a blank mold displaceable between a parison forming position and a retracted position by blank mold down air.Each section also includes a plunger which is displaceable from an elevated position down to the parison forming position and a neck ring assembly which includes an air motor. Finally the section also includes a blow mold displaceable from a remote position to a closed position. The air motor is operated from the time that the blank mold begins its displacement from the parison forming position to the retracted position by a valve which connects blank mold down air to the air motor.

Abstract: A machine for the production of glassware articles by pressing and blowing molten glass gobs fed from a glass gob feeder, comprises at least a blank mold and a corresponding pressing plunger, mounted at a stationary parison forming station, and four forming stations mounted around a 90.degree. indexed rotary carrier, each comprising a blow head, a neck ring and a blow mold, so as to rotate to a first forming position coinciding with the parison forming station, and to second, third and fourth forming positions spaced 90.degree. from each other, for reheating, blowing, and take out operations.

Abstract: In a method of and an apparatus for manufacturing a plurality of kinds of glass molding articles, a plurality of processing compartments are arranged in order of processing steps. The compartments have their functions which process glass materials to be molded which are accommodated respectively in a plurality of molds and which are different in processing condition from each other. The functions are different in property from each other. Each of the compartments is divided into a plurality of processing chambers having their functions which process the glass materials. The functions of the processing chambers of the compartment are identical in property with each other but different in condition from each other. The molds remain respectively in the processing chambers for a predetermined period of time. The molds are successively moved to their respective subsequent processing chambers to process the glass materials to form the glass molding articles.

Abstract: A mechanism for operating the molds of a glass molding machine. The glass molding machine includes a base and a table rotatably mounted on the base. The glass forming molds are operatively mounted on the rotary table. A plurality of work stations are provided on the base and cooperate to define glass molding cycle for each of the molds. The table is indexed by a drive through a preselected angle by a drive mechanism so that the molds are each moved to each of the work stations. An over the center linkage is provided for normally holding the molds in a closed position. An operating cylinder is at one of the work stations for selectively opening each mold for removal of the formed glass product during the cycle. The indexing drive moves each of the molds past the opening means at least one time during each cycle, each cycle generally being 720.degree., without opening the mold. The linkage also holds each of the molds in the open position for a selected interval for removal of the formed glass product.

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.

Abstract: Glassware forming apparatus includes a turret mounted for rotation about, and projection along, a vertical axis. First, second, third and fourth arms are rigidly mounted on said turret to extend horizontally and radially outwardly. The first arm supports a first neck ring. The second arm supports a second neck ring. The third arm supports a first blow head. The fourth arm supports a second blow head. The apparatus further includes a parison mold and first and second blow molds. Each of the blow molds is divided into two mold portions joined along a vertical hinge. The axes of the blow mold hinges extend generally parallel to the turret axis.

Abstract: Two molds attached to the same carriage and filled with molten glass in the form of a gob, are presented by a roller track from beneath a pair of blowing spindles or pipes with which the molds are nested until the glass therein is fixed or set in the clamping means of the spindles, after which the molds disengage from the parisons attached to the spindles by a descending portion of the roller track which guides their carriage. The carriages are moved along the roller track by an endless chain conveyor synchronized with the movement of the glass forming machines carrying the pair of blowing spindles. The parisons attached to the spindles are then formed and blown into the containers in the normal manner of that of a "Westlake" turntable type of glass container making machine.

Abstract: An individual section of a Hartford I. S. type glassware forming machine is modified to provide for in-line, or parallel motion, of the split mold halves at both the blank and blow stations. Vertically extending rock shafts move the blank and blow mold holder structures on fixed ways, through toggle links similar to those in a conventional I. S. machine, but the space formerly occupied by the hinge pin at the blow side is made available for the mold structure because the ways are oriented parallel to and slightly below the neck ring hub mechanism. This design provides for an increased mold closing force at the blank side and simplifies the mold holder structure itself whereby the molds can be continually cooled from an internal chamber in the mold holder which is supplied with cooling air through a vertical interface between the movable mold holder structure and the fixed machine frame.
