Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
52 words
A molten metal sampling device comprising: first wall means defining a mold chamber; second wall means defining an inlet passage for conveying molten metal into said chamber; and, valve means associated with said second wall means for closing said inlet passage in response to said second wall means reaching a predetermined temperature.
Claim 2
Dependent Claim
52 words
A molten metal sampling device comprising: first wall means defining a mold chamber; second wall means defining an inlet passage for conveying molten metal into said chamber; and, valve means associated with said second wall means for closing said inlet passage in response to said second wall means reaching a predetermined temperature.
Claim 3
Dependent Claim
52 words
The sampling device as defined in claim 1 wherein said second wall means includes at least a portion thereof which becomes soft at said predetermined temperature and wherein said valve means includes means for compressing said soft portion of said second wall means in a direction to close the passage defined thereby.
Claim 4
Dependent Claim
74 words
The sampling device as defined in claim 1 wherein said first wall means comprise a pair of mating mold sections and said second wall means comprises a tube member which extends into said chamber, said tube member being formed from a material which becomes soft at the predetermined temperature said valve means including a spring member continually acting against said tube and having sufficient force to squeeze said tube shut at said predetermined temperature.
Claim 5
Independent Claim
89 words
A device for immersion into a bath of molten metal for taking a sample of said molten metal comprising: a housing; a mold chamber in said housing; a tube member providing an inlet path for the flow of molten metal from exteriorly of said housing to said chamber; a valve means in said housing for blocking flow through said tube when said tube reaches a predetermined temperature; and, insulation means surrounding said tube to inhibit flow of heat to said tube except from molten metal flowing through said tube.
Claim 6
Independent Claim
89 words
A device for immersion into a bath of molten metal for taking a sample of said molten metal comprising: a housing; a mold chamber in said housing; a tube member providing an inlet path for the flow of molten metal from exteriorly of said housing to said chamber; a valve means in said housing for blocking flow through said tube when said tube reaches a predetermined temperature; and, insulation means surrounding said tube to inhibit flow of heat to said tube except from molten metal flowing through said tube.
Claim 7
Dependent Claim
27 words
A device as defined in claim 4 wherein said valve means comprises a spring member operative to close said tube when said tube reaches saiD predetermined temperature.
Claim 8
Dependent Claim
47 words
A device as defined in claim 4 wherein at least a portion of said tube is formed from a material which is soft at said predetermined temperature and wherein said valve means includes means for squeezing said tube shut when it becomes soft at said predetermined temperature.
Claim 9
Dependent Claim
25 words
A device as defined in claim 4 wherein said housing comprises a paper cylinder and wherein said insulation means supports said tube within said cylinder.
Claim 10
Dependent Claim
92 words
A sampling device adapted to be mounted on a lance for manual manipulation for insertion into a bath of molten metal to take a sample of said metal comprising: a housing; first wall means within said housing defining a mold chamber for receiving molten metal; second wall means within said housing defining a passageway from said mold chamber to the exterior of said housing to permit molten metal to flow into said chamber; and, valve means in said housing for closing said passageway when said second wall means reach a predetermined temperature.
Claim 11
Dependent Claim
92 words
A sampling device adapted to be mounted on a lance for manual manipulation for insertion into a bath of molten metal to take a sample of said metal comprising: a housing; first wall means within said housing defining a mold chamber for receiving molten metal; second wall means within said housing defining a passageway from said mold chamber to the exterior of said housing to permit molten metal to flow into said chamber; and, valve means in said housing for closing said passageway when said second wall means reach a predetermined temperature.
