Abstract
The invention provides an apparatus for selectively connecting a gas supply to a vessel employed to contain molten metal. Generally stated, the apparatus includes a sealer plate connected to an external portion of the vessel to receive the gas and direct it into a fluid conduit that is in fluid communication with a selected interior portion of the vessel. A seal holder disposed in approximate alignment with the sealer plate receives the gas from the gas supply and directs it toward the sealer plate. A spacing mechanism interposed between the seal holder and the sealer plate maintains a selected spaced distance therebetween and delimits the side walls of a substantially sealed gas conduit chamber when the sealer plate and the seal holder simultaneously contact opposite end portions of the side walls defined by the spacing means. The conduit chamber is thereby configured to conduct the gas directed from the seal holder toward and into the sealer plate. Additionally, the spacing mechanism is moveable laterally along a contacting, substantially planar surface of the sealer plate or the seal holder while still maintaining the conduit chamber in operative condition. A force mechanism res…
