Joint and shroud support for pour tube and collector nozzle

Abstract From the Canadian patent

A shroud or submerged pour tube which has a sealing cup of an essentially frustoconical configuration at its upper end is disclosed. The sealing cup matingly engages a bullet-shaped nose on the lower portion of the collector nozzle extending downwardly from the valve.

The shroud support assembly has adjustable length arms to permit tilting the shroud axis for alignment at the lower end of the shroud. This urges a line contact at the joint at the upper end of the shroud where it engages the bullet nose of the collector nozzle. The support …
