Abstract
Abstract A sampler for obtaining a sample from a stream of molten metal includes a split steel mold for forming a disc sample for spectographic analysis and a pin sample for combustion analysis. The split steel mold has projecting sleeve portions which receive a tube which extends from a sample pickup which is inserted in the stream of metal. A refractory disc shields the disc mold halves from metal splash and a cardboard sleeve arranged around the projecting metal parts prevents coating of the mold with metal which can interfere with removal of the sample from the mold.

Claim 5
Dependent Claim
142 words
A sampler for taking a metal sample from a stream of molten metal comprising a pair of mold parts defining a sample cavity, said mold parts including axially projecting portions, a sample pick-up tube with a tip adapted to be inserted in the stream of metal and having a passage in communication with said cavity, a refractory shield arranged around said mold projecting portions, and a paperboard sleeve arranged around said projecting portions and extending from adjacent said shield toward said tip to cover said projecting portions and including an aperture in said mold parts, a pin sample tube extending through said aperture, said tube having a vent to afford metal flow from said cavity into said pin sample tube, and an aperture in said shield and wherein said pin sample tube extends through said aperture and is supported by said shield.
