Multiple gob shearing apparatus

Apparatus for shearing four or more streams of molten glass into gobs simultaneously comprising a motor driven cam, a lever pivoted at one end to a fixed support and with its other end movable, a cam follower carried by said lever intermediate its ends, a connecting rod connected to said movable end of said lever, a first bellcrank;

• means connecting said rod to said first bellcrank, a pair of output crank arms connected to said first bellcrank, a second bellcrank, linkage means connecting said second bellcrank to the output of the first bellcrank, a third bellcrank, linkage means connecting said third bellcrank to the other output of the first bellcrank, a first and second pair of shear blade carrying arms, each said pairs of arms being mounted for equal and opposite simultaneous movements about adjacent pivot axes, two or more shear blades carried at the ends of said arms opposite the pivot axis, a molten glass feeder having four or more downwardly extending orifices for discharging four or more streams of glass simultaneously, each pair of shear arms being pivoted between a position where its blades overlap on the axis of two or more streams and the other pair of shear arms having its blades pivoted to overlap on the axis of the other two or more streams of glass, and linkage means from said second bellcrank to one arm of said pair of shear arms for operating said pair of shear arms to sever said streams into gobs, and linkage means from said third bellcrank to one of said other pair of shear arms for actuating said other pair of shear arms at precisely the same moment as the operation of the other shear arms whereby four or more streams of glass are simultaneously severed into gobs.
