Abstract

An apparatus for replaceably mounting a pouring tube in engagement with a discharge nozzle of a vessel includes an arm mounted for pivotal movement about a vertical axis and for tilting movement about a horizontal axis. A first end of the arm has a fixture for supporting a pouring tube. An operating member is mounted adjacent a second end of the arm to tilt the arm about the horizontal axis between a clamping position, where the pouring tube is pressed against a discharge nozzle of a vessel, and an open position, where the pouring tube is spaced from the discharge nozzle. When the arm is in the open position it may be pivoted about the vertical axis between a first position, where the pouring tube is aligned with the discharge nozzle, and a second position, where the pouring tube is spaced from the discharge nozzle. The operating member includes a toggle joint movable between an expanded position and a buckled position, a spring operable between the arm and the toggle joint for biasing the toggle joint to the buckled position thereof, and an actuating member for moving the toggle joint between the buckled position and the expanded position against the force of the spring.
