Abstract
A method and apparatus for shearing an elongated gob of glass from the end of a vertically flowing stream of molten glass and tilting the severed gob from its vertical orientation toward a horizontal orientation. A pair of shear blades are mounted for horizontal reciprocation between open and closed positions. In the closed position, the blades are overlapped generally in the center of the stream of molten glass and thereby shear a single gob from the stream. The movement of the blades is so controlled that the lower blade moves appreciably beyond the stream centerline. The upper blade has completed its stroke and is returning to its open position while the lower blade continues its over center travel. The difference in travel is caused by a difference in the length of the drive linkages between the upper and lower shear blades. The net result of the total cycle is to cause the severed gob to rotate about 90.degree. in mid-air before entering a forming mold.
