Abstract: A method of fabricating at least one hollow glass article by implementing fabrication cycle consisting, specifically, in stretching the blank prior to inflating it by transferring the blank into a finishing mold that includes a suction cup in its mold cavity, the suction cup being movable in translation parallel to the axis of the mold over a stretching stroke between firstly an extended position inside the mold and secondly a retracted position in which the suction cup is situated at the bottom of the mold. The method includes the step of establishing suction in the suction cup prior to the bottom of the blank coming into contact therewith, thereby uniting the bottom of the blank with the suction cup while it is placed in its extended position, and then displacing the suction cup to its retracted position in order to stretch the blank.

Abstract: A device and process for forming hollow glassware comprising producing solid glass blanks in a manufacturing line, storing the blanks, feeding the blanks to a manufacturing line for forming hollow glassware, preheating the blanks during the feeding step, supplying the preheated blanks to a heating stage, heating to form solid plastically deformable glass globs, transferring the glass gobs to a blow molding stage and blow molding the glass gobs supported by a bottom lifter in a blow mold.

Abstract: A valve hamper assembly for a glassware machine having a camming surface and a movable follower surface engaging the camming surface. A movable valve is operatively connected to the follower surface. A movement device is operatively connected to the follower surface for moving the follower surface along the camming surface to cause movement of the valve.

Abstract: A common cage assembly for a mold for a glassware machine having a mold support member. The assembly further includes a first cage member and a second cage member. Each of the cage members is movably mounted adjacent to the mold support member. Each of the cage members has a mold receiving surface.

Abstract: A bottom plate for an H-28 machine is secured to a post which is received within a hollow stud and sits on a ball bearing supported within the stud. The post which has an annular groove cooperates with a plurality of locking pins which can be held in operative relation with the post groove or released by a rotatable collar.

Abstract: A moving mechanism for moving a baffle (16), funnel or blowhead. A support (14) for the member is pivotally mounted on a first horizontal axis (20) on an arm (18) which is mounted to turn about a second horizonal axis (22) to move the member between operative and out-of-the-way positions. Driving means (24) is operable to turn the arm about the second horizontal axis and orientation means (42) maintains the member in a constant orientation during movement of the arm.

Abstract: A method and an apparatus for manufacturing hollow glass objects according to the press-and-blow process, in which a glass gob is shaped in a cooled preform mould into an elongate parison, the parison, while freely hanging at its neck portion, is then subjected to a thermal intermediate treatment and subsequently the parison is blown up in a finish mould to the desired hollow glass object and is simultaneously subjected to an upsetting operation, in such a manner that the blown-up hollow glass object at the part having larger transverse dimensions has a considerable wall thickness.

Abstract: A parison is molded from a gob of molten glass by first increasing the volume of the interior of a cup-shaped main mold body by an extra volume. Then the molten-glass gob is inserted through an upper opening into the interior of the main mold body. A neck mold comprising a split neck ring is closed on the main mold body so that the neck mold and the main mold body together define a mold cavity partly formed by the interior of the main mold body. A plunger is inserted through the neck mold down into the gob in the mold cavity to displace molten glass and shape the gob into a parison. The extra volume of the interior of the main mold body is then decreased to zero at the latest until the time at which the parison is finished, so that the molten glass rises in the mold cavity up to a level above the top of the main mold body. Finally the parison thus formed is demolded.

Abstract: A bottom plate retainer for a paste mold glassware making machine which includes a mounting block having a leaf spring mounted therein which urges a dowel member downwardly into engagement with a slot on the bottom plate.

Abstract: A parison mold and baffle system for an automatic molding machine of the I-S type including a two piece split parison mold with an integral funnel thereon. The funnel portion terminates upwardly in an annular opening with walls of outwardly tapering cross section. A combined blow-down and baffle head has blow-down nozzles, a downwardly facing annular groove which is snugly received on the walls of the funnel in both the blow-down and mold closing baffle positions. Blow-down starts from the initial engagement of the blow-down and baffle head on the funnel and continues until said mold end is completely closed by the baffle.

Abstract: A parison mold and baffle system for an automatic molding machine of I-S type includes a two piece split parison mold with an integral funnel. A combined blow-down and baffle member cooperates with the mold in a first position to perform the blow-down function and then in a second position acts as the bottle bottom end of the mold during the blow-back final shaping of the parison.

Abstract: A mold assembly and method for automatically making crown bottom blown glassware wherein a charge of molten glass is shaped into a hollow preform in a parison mold by means of a plunger. The hollow preform or parison is removed from the parison mold and placed in a finishing mold having a bottom forming assembly comprised of an annular member slidably contained in the bottom end of the finish mold and a domed central member slidably mounted in the annular member such that it can be reciprocated from a normally retracted position level with or slightly below the top surface of the annular member to a position above that surface.

Abstract: A process and apparatus for the manufacture of large glass containers, comprises preparing a glass gob of a predetermined weight in an automatic mechanical feeder and feeding it to a first preparatory mold at a predetermined frequency. A parison is formed in the preparatory mold, at the same frequency, the parison comprising a finished mouth of the glass container to be formed. The parison is then transferred to a second, prefinishing mold, and, at the same frequency, a prefinished parison is formed. The prefinished parison is transferred to a third, finishing mold, and, at a frequency in a ratio of from 1:1 to 1:4 of the predetermined frequency, the finished glass container is formed. The expansion of the prefinished parison is controlled by the action of compressed air conveyed to the interior of the parison from its mouth.

Abstract: An individual section of a multiple section glassware forming machine is shown wherein each such section preferably includes three stations performing separate and sequential operations in forming articles of glassware. Each such section may be adapted for "single gob" or "multiple gob" use whereby each station in the section performs its operation in forming either a single article of glassware or multiple articles at the same time. The section shown is adapted for "double gob" operation. Its first station is utilized in forming (by overhead pressing plungers) two parisons in upright parison molds. Its second station is utilized to further form the parisons either in intermediate blow molds or by suspending the parisons for a re-heat. Its third station is utilized to blow the parisons into the final shape of the glassware article being made.
