ABSTRACT ADJUSTABLE MOUNTING FOR MULTIGOB APPARATUS FOR STRAIGHT LINE SHEARING The improved apparatus for straight line shear- ing of multiple gobs from columns of molten glass includes a shear frame to which multiple shear blade assemblies and shear blade adjustment mechanisms are mounted to facilitate changeover between single, double, and multiple gob configurations. At least one shear frame wall includes a plurality of slots aligned along an axis of separation of the shear blade assemblies and shear blade adjustment mechan- isms, the adjustment mechanisms each including an indexing rod and adjusting shaft which may be repo- sitioned within one of said slots to adjust the separation of the shear blade adjustment mechanisms. Advantageously, in a shear mechanism designed to accommodate single, double, and triple gob configur- ations, two such slots are provided for the outer- most indexing rods, such rods being located at their points of maximum separation for single or triple gob shearing, and their points of minimum separation for double gob shearing. In order to provide a more remote manual adjustment of the shear blade adjust- ment mechanisms, each indexing rod may be geared to a transverse rod which is journaled in an extension plate of the shear frame; in such embodiment, the extension plate includes slots corresponding to the slots in the shear frame wall in order to permit repositioning of the transverse shafts commensurate with that of the indexing rods.
