Abstract: The individual section of a Hartford I. S. type machine is modified to permit forming the parisons in an upright orientation, and also for transferring the upright parisons from the blank to the blow side of the section without disturbing this upright orientation. The pressing plungers at the blank station are mounted for movement toward and away from the upwardly open blank mold cavities, and each blank mold cavity is defined in part by partible neck ring molds, in part by a lower solid blank or body mold, and finally by intermediate partible mold sections which engage the upper neck ring molds and also the lower body mold. These intermediate mold sections at the blank side of the machine are mounted on the existing blank mold holder arms.

Abstract: The neck ring arms of a Hartford I. S. type glassware forming machine section are adapted to be oscillated between a blank and a blow station, and also to move toward and away from one another in order to cooperate with one another and with a blank mold at the blank side of the machine, and to release a partially formed parison at the blow side of such a machine. In a triple gob configuration, where three such neck ring molds are provided, cartridges are disclosed for conveniently mounting the six neck ring mold segments for quick assembly with the associated neck ring arms. The cartridges can be quickly removed with a minimum downtime to the machine section, and the neck ring mold segments bench-assembled in the cartridge at the leisure of the machine operator.
