Glass gob shear blade mounting apparatus

Apparatus for shearing a stream of molten glass into individual globs, said apparatus comprising:

• a first shear blade having a shearing end and a distant end, said first shear blade being moveable toward and away from a stream of molten glass to periodically bring said shearing end of said first shear blade into contact with the stream of molten glass;
• a second shear blade having a shearing end and a distant end, said second shear blade being moveable toward and away from the stream of molten glass to periodically bring said shearing end of said second shear blade into contact with the stream of molten glass and with said shearing end of said first shear blade;
• means for mounting one of said first shear blade and said second shear blade to position said one of said first shear blade and said second shear blade slightly out of parallel with the other of said first shear blade and said second shear blade, to thereby reduce contact loads whereby said first shear blade and said second shear blade make contact with one another;
• and
• means for resiliently mounting the other of said first shear blade and said second shear blade to permit said other of said first shear blade and said second shear blade to deflect upon engagement with said one of said first shear blade and said second shear blade to further reduce contact loads when said first shear blade and said second shear blade make contact with one another;
• wherein said second shear blade comprises a second blade element, a second backup element, and means for securing said distant end of said second blade element to said second backup element,
• wherein said means for resiliently mounting comprises a second blade holder, means for securing said second backup element to said second blade holder, curved spring washer means positioned between said second backup element and said second blade holder, second curved spring washer means positioned between said second backup element and said second blade holder, said second curved spring washer means being spaced from said curved spring washer means along an axis extending from said shearing end to said distant end of said other of said first shear blade and said second shear blade.
