ABSTRACT:
Apparatus for the shearing of three or more gobs of glass simultaneously wherein the shear mechanism is of the straight line type such that the shears move toward and away from each other with linear motions and the shearing mechanism is provided with drop guides which will function to control the drop of the gob after it has been sheared and in which the drop guides which are carried by the mechanism which drives the upper shear blades may be adjusted with respect to the instant when they will be arrested in their movement and this adjustment may be carried out on the fly with the individual drop guide for each of the gobs being individually adjustable while the mechanism is in operation without requiring interruption of the feeding of glass gobs to the forming machines that are being served.
