A workpiece manipulating apparatus for faceplate panels of cathode ray tubes includes a conveyor for carrying panels along two groups of grinder stations in a pattern coordinated with carriage mounted loaders which move along the conveyor. The conveyor indexes to loading stations as do the loaders. Unground panels are sequenced to the stations as the loaders are present. Loaders pick the unground panels from the conveyor and transfer them to an orienting station which orients panels for loading into a grinder. Loaders pick an oriented panel from the orienting station and load it in to the grinder at the loading station. They also picks up ground panels from the grinder and place them in a reorient station and picks ground panels from the reorient station and places them on the conveyor in the position from which they removed an unground panel. The loader advances to a next loading station to load a next grinder and the conveyor with panels picked up at the preceeding station. The cycle is continuous with the panel manipulation through a complete cycle approximating the grinding time of a panel in a grinder.

Method of and apparatus for automatically grinding cathode ray tube

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.
