Abstract A device for immersion in molten material for obtaining a sample and/or measuring the temperature. For obtaining a sample the device is comprised of a body structure including a cavity for reception of a sample of molten material. An entrance to the cavity may be closed by a fusible cap. The body structure is supported at the immersion end of a protective cardboard tube. A handle extending into the cardboard tube is employed to immerse the body structure in a bath of molten material. The device may or may not include one or more heat sensing devices for measuring the temperature of a sample as it cools and/or for measuring the temperature of the bath of molten material from which a sample may be taken. The device of this invention is characterized by the inclusion of a heat shielding protective enclosure surrounding the immersion end. The enclosure is automatically separable from the device upon immersion in a bath of molten material and moves away from its shielding position.
A device for immersion in a molten material for collecting a sample thereof comprising: an immersible body structure having therein a cavity with an entrance portion for reception of a sample of molten material, a fusible closure covering said entrance portion, a tubular housing supporting said body structure and its fusible closure at an immersion end thereof, a separable heat shielding protective structure having a configuration to form an extension of said tubular housing, and heat destructible means at adjacent ends of said tubular housing and said heat shielding protective structure to secure said heat shielding protective structure in surrounding relation with said fusible closure during passage through a zone at elevated temperature above said molten material, said heat destructible means, however, being separable by action of said molten material in a manner effecting separation of said heat shielding protective structure for movement thereof away from its heat shielding position.
