ABSTRACT:
The specification and drawings disclose an embodiment of an apparatus for taking samples from a flowing stream of molten metal. The apparatus comprises a container defining a sample mold cavity having a flat mold sample chamber and a pin sample chamber that are interconnected. The apparatus is so designed that a sample tube communicating with the mold cavity can be placed in the stream of molten metal to fill the cavity with a quantity of sample metal. The apparatus is externally ribbed to facilitate slidable housing in a suitable protective shield so that the sample tube may be selectively exposed for use in drawing a sample. The sample tube, mold sample chamber and pin sample chamber define a flow path which creates a turbulent flow of molten metal in the sample chambers thereby to equalize the carbon content of the sample metal in both the pin sample and mold sample chambers. The apparatus is preferably formed from molded sand and employs chill discs and vents to respectively aid in freezing the molten metal and to allow egress of air from the sample cavity.
