Claim 1
Independent Claim
70 words
A device for the purpose described comprising: a housing, a subassembly comprising a sleeve, means supported in said sleeve for receiving a sample of molten metal, a thermocouple supported in said sleeve in relation to said receiving means, said subassembly being insertable into said housing whereby said sleeve may be secured thereto, and a second sleeve which is insertable into said housing for receiving an inner end of a wand.
Claim 2
Independent Claim
70 words
A device for the purpose described comprising: a housing, a subassembly comprising a sleeve, means supported in said sleeve for receiving a sample of molten metal, a thermocouple supported in said sleeve in relation to said receiving means, said subassembly being insertable into said housing whereby said sleeve may be secured thereto, and a second sleeve which is insertable into said housing for receiving an inner end of a wand.
Claim 3
Dependent Claim
37 words
The device defined in claim 1, in which said thermocouple is supported in said sleeve in a substantially parallel relationship to said receiving means with a lower end of the thermocouple being located below said receiving means.
Claim 4
Dependent Claim
49 words
The device defined in claim 1, including a tube which is secured in said sleeve for supporting said thermocouple, and conductor means which are operatively connected to said thermocouple and extends outwardly from said tube for connection with a recording apparatus located at a remote distance from said device.
Claim 5
Dependent Claim
37 words
The device defined in claim 1, in which said thermocouple is supported in a tube, said subassembly includes a cup containing a mass of cement, and said receiving means, and said tube are mounted in said mass.
Claim 6
Dependent Claim
64 words
The device defined in claim 1, in which said subassembly includes a first cup containing a mass of cement and a plurality of nested cups forming a plurality of chambers, said receiving means is mounted in said mass and communicatively connects with one of said chambers, and a tube supports said thermocouple so that the latter is disposed in one of the other chambers.
Claim 7
Independent Claim
56 words
A device for the purpose described comprising: a housing, a subassembly comprising a sleeve, a mass of cement in said sleeve supporting means for receiving a sample of molten metal, a thermocouple supported in said mass in relation to said receiving means, said subassembly being insertable into said housing whereby said sleeve may be secured thereto.
Claim 8
Independent Claim
56 words
A device for the purpose described comprising: a housing, a subassembly comprising a sleeve, a mass of cement in said sleeve supporting means for receiving a sample of molten metal, a thermocouple supported in said mass in relation to said receiving means, said subassembly being insertable into said housing whereby said sleeve may be secured thereto.
Claim 9
Dependent Claim
24 words

Claim 10
Dependent Claim
34 words
The device defined in claim 6, in which said receiving means and said thermocouple are disposed in a substantially parallel relationship with a lower end of the thermocouple being located below said receiving means.
Claim 11
Dependent Claim
38 words
The device defined in claim 6, in which said thermocouple is supported in a tube located in said sleeve, said subassembly includes a mass of cement, and said receiving means and said tube are mounted in said mass.
Claim 12
Independent Claim
59 words
A device of the kind described comprising an outer elongated tube, a lower sleeve disposed in said tube and supporting insulated means for receiving a sample of hot liquid and a thermocouple, and an upper sleeve disposed in said tube in axially spaced relation to said lower sleeve for receiving a wand whereby to facilitate manipulation of the device.
Claim 13
Independent Claim
59 words
A device of the kind described comprising an outer elongated tube, a lower sleeve disposed in said tube and supporting insulated means for receiving a sample of hot liquid and a thermocouple, and an upper sleeve disposed in said tube in axially spaced relation to said lower sleeve for receiving a wand whereby to facilitate manipulation of the device.
Claim 14
Dependent Claim
21 words
The device defined in claim 10, including conductors which are connected to said thermocouple and extend outwardly through said upper sleeve.
