ABSTRACT:
In apparatus for the straight-line shearing of molten glass gobs, first and second carriage members have mounted thereon one or more opposing pairs of shear blades which are caused reciprocally to move towards each other and then away from each other along a substantially straight line between an open position and a closed cutting position. The carriage members are slidably mounted on wayrods and are connected to diametrically opposed crank arms extending from a rotatably driven shaft. As the shaft is caused to rotate, the carriage members reciprocally slide on the wayrods between the open and closed positions.
