<p>GLASSWARE FORMING MACHINE OF THE I. S. TYPE FOR UPRIGHT PRESS AND BLOW PROCESS 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. The neck ring molds are provided in a structure which is pivotally supported at the free ends of the two neck ring arms, and while these arms are conventionally mounted for pivotal movement in the neck ring mechanism, means is also disclosed for restricting these neck ring structures to so support the parisons that each remains in an upright orientation during transfer from the blank to the blow side of the machine section.</p> |
