  • Patent number: 5766292
    Abstract: A method and apparatus for forming a hollow glass article comprises delivering a gob of glass to a blank mold, providing a first neck ring to a position adjacent the blank mold, forming the gob in the blank mold into a parison, moving the first neck ring to transfer the parison to a blow mold, blowing the parison in the blow mold to a hollow article, releasing the engagement of the first ring with the hollow article, moving the first neck ring away from the blow mold, removing the hollow article from the blow mold, returning the first neck ring to a position adjacent the blank mold to repeat the cycle, providing a second neck ring adjacent the blank mold while the first ring is moving toward the blow mold, delivering a second gob of glass to the blank mold while the second ring is in position adjacent the blank mold, forming the second gob into a second parison, moving the second parison to a position adjacent the blow mold while the first neck ring is being returned to a position adjacent said blank mold; an

  • Patent number: 4772306
    Abstract: A gob delivery system for molten glass charges or gobs from a multiple orifice feeder to a plurality of parison molds in which the transmit times of the gobs are held to a minimum. The gob scoops, which initially deflect the gobs into straight troughs, are formed with a spiral curve to impart less of a curve to the charge. The deflectors which receive the gobs or charges from the troughs are also formed as spiral curves so that the gobs will be presented to vertical guide tubes with a minimum of angular distortion to give more consistent loading.
