Claims3
A glass batch charger for charging batch glass-forming materials into a melt furnace, which includes:
- a stationary box of hollow arcuate construction having a part-circular opening and coolant circulation paths extending throughout the hollow arcuate construction,
- an oscillating box of hollow part-circular construction disposed within and rotatably supported about an oscillation axis within the part-circular opening of the stationary box, the oscillating box having coolant circulation paths extending throughout the hollow part-circular construction, and
- means for circulating coolant at least through the stationary and oscillating boxes,
- characterized in that
- the coolant circulation paths in the stationary box are arcuate throughout substantially their entire length and concentrically incurvate about the oscillation axis of the the part-circular opening, and
- the coolant circulation paths in the oscillating box are arcuate and concentrically disposed about the oscillation axis and shaped to follow the contour of a rear wall of the oscillating box.
