Molten metal transfer vessel and method of construction
First Claim
1. A vessel for use in a system for transferring molten metal, the vessel including (a) a first end through which molten metal enters, (b) a second end through which molten metal exits, (c) a cavity, (d) a transfer chamber with an open top;
- an opening in communication with the cavity;
an uptake section above and in communication with the opening; and
an outlet above the opening, the outlet in communication with the uptake section and;
(e) a launder in communication with the outlet and in communication with a second vessel, wherein the second vessel is separate from the first vessel and does not share a common wall with the first vessel.

Abstract
The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.

6. A transfer chamber system for use with a vessel including a cavity for containing molten metal, the transfer chamber system being in fluid communication with the vessel cavity and including:
-
(a) an open top through which a molten metal pump is received; (b) an inlet in communication with the cavity to permit molten metal to enter the transfer chamber; (c) an enclosed inner section and an open section, the enclosed inner section having a first opening in communication with the open section; (d) the molten metal pump positioned in the transfer chamber, the pump having a motor, a drive shaft having a first end connected to the motor, and a second end, and a rotor connected to the second end, wherein the shaft is positioned at least partially in the enclosed inner section and the rotor is positioned at least partially in the enclosed inner section; (e) an outlet above the first opening and below the motor, wherein molten metal can exit the transfer chamber through the outlet; (f) wherein the rotor has a diameter, and the enclosed inner section has an interior diameter, and the interior diameter is between ⅛
″
to 1″
greater than the diameter of the rotor;wherein, as the pump operates the rotor is rotated and directs molten metal up into the enclosed inner section and out of the outlet. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22)
