Abstract
Abstract The specification and drawings disclose three embodiments of an apparatus for taking samples from a flowing stream of molten metal. The preferred embodiment comprises a separable sample mold having a thermal shock resistant tube connected thereto. The mold and tube are slidably mounted in a cylindrical, open ended housing. The housing is arranged to totally enclose the mold and tube in a first position. In a second position the tube extends out of the housing for sample taking. Other features disclosed include an arrangement for providing a small diameter pin of sample metal and a system for bonding a hook or loop of metal in the sample for tagging purposes. Also disclosed is a sampling device wherein the mold chamber can be continually reused with only the sample tube portion being a replaceable component.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
In an apparatus for taking a sample from a flowing stream of molten metal and including a plurality of separable mold formiNg elements which cooperate to form a mold chamber, and a first temperature and thermal shock resistant tube extending outwardly from said chamber to direct a molten metal from the stream into the mold chamber, the improvement comprising: a sample tagging member positioned between said mold forming elements and including a first end portion extending into said chamber and a second end portion extending out of said chamber.
Claim 2
Dependent Claim
89 words
In an apparatus for taking a sample from a flowing stream of molten metal and including a plurality of separable mold formiNg elements which cooperate to form a mold chamber, and a first temperature and thermal shock resistant tube extending outwardly from said chamber to direct a molten metal from the stream into the mold chamber, the improvement comprising: a sample tagging member positioned between said mold forming elements and including a first end portion extending into said chamber and a second end portion extending out of said chamber.
Claim 3
Dependent Claim
27 words
The improvement as defined in claim 6 wherein said tagging member comprises a generally U-shaped wire loop with the legs of the loop extending into the chamber.
Claim 4
Dependent Claim
161 words
In an apparatus for taking a sample from a flowing stream of molten metal and including a plurality of separable mold forming elements which cooperate to form a mold chamber, and a first temperature and thermal shock resistant tube extending outwardly from said chamber to direct a molten metal from the stream into the mold chamber, the improvement comprising: a second tube formed of temperature and thermal shock resistant material extending from said chamber, said second tube being hollow and having first and second ends with said first end opening into said chamber to permit molten metal to flow from said chamber into said second tube and said second end including means to prevent molten metal from passing therethrough while allowing air to escape from within said second tube during a sample taking operation; and, wherein said second tube is closely adjacent said first tube and positioned so as to be protected by said first tube during a sample taking operation.
Claim 5
Dependent Claim
161 words
In an apparatus for taking a sample from a flowing stream of molten metal and including a plurality of separable mold forming elements which cooperate to form a mold chamber, and a first temperature and thermal shock resistant tube extending outwardly from said chamber to direct a molten metal from the stream into the mold chamber, the improvement comprising: a second tube formed of temperature and thermal shock resistant material extending from said chamber, said second tube being hollow and having first and second ends with said first end opening into said chamber to permit molten metal to flow from said chamber into said second tube and said second end including means to prevent molten metal from passing therethrough while allowing air to escape from within said second tube during a sample taking operation; and, wherein said second tube is closely adjacent said first tube and positioned so as to be protected by said first tube during a sample taking operation.
Claim 6
Dependent Claim
146 words
In an apparatus for taking a sample from a flowing stream of molten metal and including a plurality of separable mold forming elements which cooperate to form a mold chamber, and a first temperature and thermal shock resistant tube extending outwardly from said chamber to direct a molten metal from the stream into the mold chamber, the improvement comprising: a second tube formed of temperature and thermal shock resistant material extending from said chamber, said second tube being hollow and having first and second ends with said first end opening into said chamber to permit molten metal to flow from said chamber into said second tube and said second end including means to prevent molten metal from passing therethrough while allowing air to escape from within said second tube during a sample taking operation; and, wherein said first and second tubes are bonded in side-by-side relationship.
Claim 7
