ABSTRACT:
A glass gob delivery system for conveying gobs of molten glass from an oscillating gob delivery chute to a blank mold of a glass container forming machine of the I.S. type. The delivery system comprises an elongate trough that extends downwardly from an inlet to an outlet and a deflector with an inlet near the outlet from the trough and an outlet near the blank mold. The trough has a cross-section in the form of an upwardly facing U whose opposed legs extend parallel or substantially parallel to one another, the spacing between the opposed legs tapering gradually from a greater spacing at the inlet to a lesser spacing at the outlet. The deflector has a curved portion that curves downwardly from a higher elevation at a location near the inlet to a lower elevation at a location away from the inlet and has a cross-section in the shape of a downwardly facing U whose opposed legs extend parallel or substantially parallel to one another, the spacing between the opposed legs of the deflector gradually tapering from a greater spacing at the inlet to a lesser spacing at the outlet. The trough and the deflector are formed from an aluminum alloy with gob contacting surfaces that are coated with a nickel-graphite composition.
