Patent ID: 8613884

Claim:
An insert for transferring molten metal out of a vessel, the insert for being used in combination with a molten metal pump having an outlet through which a stream of molten metal is generated, the insert defining an enclosed cavity and comprising: (i) one or more outer walls and a bottom; (ii) a first opening in the lower half of one of the one or more outer walls, the first opening leading to the enclosed cavity, the first opening being positioned so that it is in fluid communication with a discharge, such that at least part of the stream of molten metal exiting the discharge passes through the first opening and into the enclosed cavity; (iii) a second opening in a top of the insert; and (iv) a trough positioned at the top of the insert, the trough having a back wall that is positioned behind the second opening and that extends above the second opening and a first side wall positioned on one side of the second opening, and a second side wall positioned on the opposite side of the second opening, wherein the first wall and second side wall each extend above the second opening, the trough further including a bottom surface angled towards the second opening; whereby, as the molten metal pump pumps molten metal, at least some of the molten metal passes through the first opening and into the cavity so that the level of molten metal in the cavity rises so that molten metal exits the second opening and passes through the trough and out of the vessel.
