Abstract
Gob-shearing apparatus for providing a predetermined amount of a molten glass article vertically transferred from a feeder bowl which is capable of performing two cutting strokes when a pair of hydraulic cylinders having a rack gear reciprocates, thus obtaining an improved sheared surface of the gob. The apparatus includes a driving pinion engaged with and rotated by the reciprocation, a pair of driven pinion engaged with the driving pinion and rotated by the rotation of the driving pinion, a pair of first links having a blade on its free end, a pair of second, third and fourth links which are linked between the first link and driven pinion for link motion, and a guide rail for guiding the circular movement of the first links.
