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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
Apparatus for taking samples from a stream of molten metal comprising: container means forming a mold chamber for receiving a sample quantity of said molten metal; a sample tube communicating with said chamber and having an open end adapted to be placed in said stream of molten metal to supply said metal to said chamber; a tubular housing enclosing said container means and said sample tube, said housing having a length at least as great as the combined length of said container means and said sample tubes, said container means and said sample tube being mounted in said housing for selective movement between a first position wherein said sample tube is within said housing to a second position wherein said sample tube extends from said housing for sample taking.
Claim 2
Dependent Claim
129 words
Apparatus for taking samples from a stream of molten metal comprising: container means forming a mold chamber for receiving a sample quantity of said molten metal; a sample tube communicating with said chamber and having an open end adapted to be placed in said stream of molten metal to supply said metal to said chamber; a tubular housing enclosing said container means and said sample tube, said housing having a length at least as great as the combined length of said container means and said sample tubes, said container means and said sample tube being mounted in said housing for selective movement between a first position wherein said sample tube is within said housing to a second position wherein said sample tube extends from said housing for sample taking.
Claim 3
Dependent Claim
26 words
The apparatus as defined in claim 1 wherein said tubular housing comprises an open ended cylinder having an internal diameter to slidably receive said container means.
Claim 4
Dependent Claim
36 words
The apparatus as defined in claim 1 wherein said sample tube is joined to said container means by a refractory cement and wherein said sample tube is formed from a temperature and thermal shock resistant material.
Claim 5
Dependent Claim
46 words
The apparatus as defined in claim 1 wherein said housing is opened at both ends and slidably receives said container means and wherein a disc-shaped collar is positioned about a said sample tube and extends radially outward into slidable engagement with the walls of said housing.
Claim 6
Dependent Claim
19 words
The apparatus as defined in claim 1 wherein said housing comprises a paper board tube opened at both ends.
Claim 7
Dependent Claim
15 words
The apparAtus as defined in claim 1 wherein said sample tube is formed from quartz.
Claim 8
Dependent Claim
142 words
Apparatus for taking a sample from a stream of molten metal comprising: container means forming a mold chamber for receiving a quantity of said molten metal, said container means including a pair of mating mold sections having cooperating portions providing an inlet channel; a sample tube positioned in said channel for directing molten metal into said mold chamber, said sample tube being bonded to said container means by a refractory cement; a housing enclosing said container means and said sample tube, the length of said housing at least as great as the total length of said container means and said sample tube; and, said container means and said sample tubes slidably mounted within said housing for movement between a first position wherein said sample tube is enclosed by said housing to a second position wherein said sample tube extends from said housing.
Claim 9
Dependent Claim
142 words
