Molten metal transfer device
First Claim
1. A molten metal transfer device for withdrawing a selected quantity of molten metal from a bath, comprising:
- (a) structure defining a chamber, a portion of the chamber being disposed within the bath, the chamber being oriented generally vertically and positioned relative to the bath such that a portion of the chamber is disposed beneath the surface of the molten metal and a portion of the chamber is disposed above the surface of the molten metal;
(b) a first opening included as part of the structure through which molten metal can flow from the bath into the chamber;
(c) a second opening included as part of the structure through which molten metal can flow outwardly from the chamber, the second opening being located at a vertical position above that of the first opening;
(d) a cup-like bucket disposed within the chamber for vertical reciprocating movement therein, the bucket having a sidewall and a bottom, the bucket at its lowermost position being at or below the level of the first opening and at its uppermost position being above the level of the first opening;
(e) a generally vertically oriented slot included as part of the sidewall of the bucket, the slot in use being positioned adjacent the second opening when the bucket is in the uppermost position, the slot enabling molten metal carried by the bucket to flow outwardly of the bucket through the second opening, the amount of metal flowing outwardly of the bucket being dependent upon the vertical position to which the bucket is displaced; and
(f) means for requiring molten metal to enter the first opening from beneath the surface of the bath and preventing molten metal from entering the first opening from the surface of the bath.

Abstract
A molten metal transfer device for withdrawing a selected quantity of molten metal from a bath includes structure defining a chamber disposed within the bath, the chamber including a first opening through which molten metal can flow from the bath into the chamber and a second opening through which molten metal can flow outwardly from the chamber. A cup-like bucket is disposed within the chamber for vertical reciprocating movement, the bucket having a generally vertically oriented slot included as part of its sidewall. The device includes a displacement mechanism for urging the bucket laterally toward engagement with the surface of the chamber. The device also includes mechanisms for easily removing buckets and chambers and replacing them with new buckets and chambers.
