  • Patent number: 5928400
    Abstract: A mounting structure for use in a glassware forming machine for moving an operative member, such as a funnel, baffle or blowhead, between an out of the way and operative positions. The machine comprises a vertical operating shaft and a parallel support shaft, and the mounting structure comprises a first link adjustably mounted on the operating shaft and a second link slidably mounted on the support shaft. The two links are both pivoted to a head and form a parallel linkage with it. A key and keyway, maintains the first link in a desired angular relationship with the operating shaft. The head is provided with a releasable device by which the operative member may be secured to the head in a desired angular relationship.

  • Patent number: 4978380
    Abstract: A mould mechanism for a glass forming machine comprises two mould supports which have first end portions which are mounted on parallel shafts for linear movement between mould open and mould closed positions. The mould supports are moved by mould operating mechanisms which each comprise a hydraulically operated piston and cylinder device providing one of the shafts. A clamping mechanism is provided to latch the mould supports together when in mould closed position.

  • Patent number: 4878935
    Abstract: The mechanism supports mould side portions (10;110) on an upper support (50;150) and a lower support (52;152) both mounted on an arm (14) for limited movement in a horizontal plane. A force apportioning member (62;162) is mounted on the arm and pivotally engages both supports. The force apportioning member (62;162) pivots on a horizontal axis between the supports to apportion mould closure force between the supports. The pivots may be provided by spherical bearings (64,70;164;170).

  • Patent number: 4861365
    Abstract: Mould side portions (10; 110; 210) of three moulds are supported by a mechanism arranged to equalize mould closure force between the three moulds. Three mould side portions are supported by a triple support (50, 52; 150, 152; 250; 350) centrally pivotally mounted. The opposed mould side portions are mounted two on a double support (32; 232; 332) which is pivoted on a pivot (24; 224; 324) aligned with a line passing centrally between the center mould and one of the other moulds and one on a single support (40, 42; 240; 340) which is pivoted on a pivot (26; 226; 326) aligned with the center-line of the other of said other moulds.
