Apparatus for the shaping and transferring of glass articles or other materials

Apparatus for shaping and transferring of a glass article in a glass forming machine, said shaping of said glass article being in a blowing mold, said transferring of said glass article being from said blowing mold to a deadplate in the front of the glass forming machine, comprising:

• a support structure;
• a housing supported by said support structure;
• means for forming the glass article, said glass article being formed from a glass parison, said means for forming the glass article comprising:
• means for blowing air inside the glass parison so as to form the glass article, said means for blowing air being supported by said housing for movement along a first longitudinal axis of said housing, said means for blowing air comprising:
• a cylinder coupled on an upper part of the support structure;
• a movable blow nozzle to provide blown air for the forming of the glass article and a cooling of the glass article once said glass article has been shaped;
• a movable blow head to form a pressure chamber when said blow head is positioned on the blowing mold during the shaping of the glass article, said blow nozzle passing within and through said blow head;
• and
• means for moving said blow nozzle and said blow head, said means for moving being located within said housing, said blow nozzle and said blow head being secured to a lower part of the means for moving, said means for moving comprising:
• a first hollow central fixed shaft within said cylinder;
• a second hollow central shaft coupled between an internal part of said cylinder and the first hollow central fixed shaft, said second hollow central shaft being moved vertically through the internal part of the cylinder, said second hollow central shaft being connected at its lower end with the blow nozzle, said second hollow central shaft being movable with a first downward movement to permit a flow of blown air through the blow nozzle for forming the article in the blowing mold and a second upward movement to permit a flow of blown air through the blow nozzle for cooling the glass article during said transferring of said glass article from said blowing mold to said deadplate;
• and
• a third hollow shaft placed around the second hollow central shaft, said third hollow shaft being connected by its lower end with the blow head and moveable simultaneously with the second hollow central shaft, said third hollow shaft and blow head being independently retracted from the second hollow central shaft with an upward movement to permit a means for gripping the glass article to grip the glass article;
• and
• means for gripping the glass article, said means for gripping the glass article being supported by said housing, said means for gripping the glass article being combined with said means for forming the glass article within a single mechanism, said means for gripping the glass article comprising:
• means for gripping mounted in an external part of said housing for a first movement of a first portion of said means for gripping between a gripping position to grip the glass article after said glass article has been shaped in the blowing mold and a retracted position to release the glass article, said first movement being produced by a second movement and a third movement of a second portion of said means for gripping and a third portion of said means for gripping, respectively, along a second longitudinal axis of said housing and a third longitudinal axis of said housing, respectively.
