Apparatus for blow molding hollow glassware

A blow molding multiple-section machine for the manufacture of hollow glass ware comprising:

• a common base and at least one vertical shaft carried by said base;
• at least one neck ring arm mounted at a point between the ends thereof on said vertical shaft for oscillating movement in a horizontal plane;
• means for moving said neck ring arm to position opposite ends of said arm alternately to molding and takeout positions 180 degrees apart, said neck ring arm having at least two rotatable neck rings, at least one on each side of the axis of oscillation of said neck ring arm;
• an articulated two-part blow mold carrier pivoted on said base below said neck ring arm on one side of the axis of oscillation, said blow mold carrier having at least one two-piece facing blow mold when in one position and another two-piece blow mold adapted to assume facing position when the blow mold carrier is moved 180 degrees, said blow mold carrier being so interconnected that one blow mold is closed when the other is open, said blow molds when closed being in axial alignment with respective neck rings on that side of said neck ring arm;
• at least one parison mold and cooperating plunger means carried by said base and operating in timed relation to movements of said neck ring arm for forming a preform supported by one of said neck rings when either end of said neck ring arm is in said molding position and the corresponding blow mold is open;
• means for closing the open blow mold on said preform while simultaneously opening the other of said blow molds while said neck ring arm remains stationary;
• means for blowing said preform into final shape in said closed blow molds while said arm remains stationary;
• means for simultaneously oscillating said neck ring arm and mold carrier 180 degrees while continuing blowing to cool the glass ware in the closed blow means;
• means operable during oscillation of said neck ring arm and mold carrier for spray cooling the open blow mold to prepare it for the next preform;
• and
• means for opening the closed blow mold from the finished cooled glass ware and releasing the glass ware to a takeout means and simultaneously closing the cooled blow mold around the next preform.
