Abstract
The feeder tube in a molten glass gob feeder is mounted in a holder which is supported in the feeder structure by a pair of opposed hollow shafts. The shafts are vertically adjustable by the fact that they have their lower ends threaded onto vertical screws. The vertical screws are mounted for rotation about their vertical axes, in unison, to effectively raise or lower the shafts as desired. A scale and pointer arrangement indicates the tube height relative to the feeder bottom. The feeder tube is mounted in the holder such that reciprocation of a plunger in the tube will not raise the tube relative to the feeder.
