ABSTRACT:
A vessel for liquid, especially a ladle for molten metal, is constructed and arranged to facilitate pouring of the contents in a uniform stream along a predetermined path under a uniform pressure head, while facilitating starting and stopping of the stream. To this end, the vessel is supported for rotation about first and second generally horizontal, transverse, axes. The liquid is discharged from an outlet in the vessel located on the first axis when the vessel is rotated about the first axis. By controlling rotation, a constant head of liquid and uniform discharge trajectory is established. Flow is conveniently interrupted by rotation of the vessel about the second axis to tilt the first axis and raise the discharge outlet by an amount equal to the liquid head. Flow is restarted by lowering the discharge outlet to its original position. Preferably, the first axis is horizontal during discharge. In a preferred use of the vessel, the vessel and a receptacle, such as a mold, are moved by independent drives along adjacent paths as liquid is poured into the receptacle. A movable abutment carried with the vessel engages structure associated with the receptacle to keep the vessel and receptacle aligned during pouring.
