Abstract
A glass feeder which discharges parallel runners of molten glass which can be sheared into discrete gobs for processing in a glass container forming machine. The spout bowl has a neck portion at the bottom which includes a discharge passage. This passage is circular at the top where it communicates with the bottom surface of the spout bowl and oblong at the bottom where it communicates with a corresponding oblong opening in a bathtub shaped orifice ring. The orifice ring has a closed oblong shaped bottom smaller than the oblong opening and has a plurality of discharge holes defined along a straight line.

- a spout bowl including a neck portion at the bottom thereof, said neck portion having a vertical discharge passage extending therethrough from an upper inlet opening to a lower outlet opening,
- said upper inlet opening being circular,
- said lower outlet opening being oblong defined by major and minor dimensions and said vertical discharge passage vertically transitioning from said circular upper inlet opening to said oblong lower outlet opening proceeding from said upper inlet opening to said lower outlet opening,
- said circular upper inlet opening having a size, relative to said oblong lower outlet opening, so that the oblong lower outlet opening is located completely within said circular upper inlet opening, and
- an orifice ring for receiving molten glass from said oblong lower outlet opening, said orifice ring including a plurality of discharge holes through which said plurality of runners of molten glass can flow.
