Claim 5

The device of claim 1 wherein said body member has a second end and further including adapter means attached to said second end, said one element of said cooperating adjustment means being fixedly associated with said body member by said adapter means.

Claim 6

The device of claim 4 wherein said second end of said body member has an enlarged diameter recess therein, gasket means positioned in said recess, said adapter biasing against said gasket means and holding said gasket means in sealing engagement around said thermocouple member and against the bottom of said recess.

Claim 7

The device is claim 5 and further including a cylindrical plug positioned between said adapter and said gasket means around said thermocouple member.

Claim 8

The device of claim 4 wherein said adapter means has position indicating means formed on the exterior thereof and said knob means includes a cylindrical portion surrounding said position indicating means.

Claim 9

An adjustable thermocouple assembly comprising; and elongated body member having a longitudinal bore therethrough and first and second ends, an elongated thermocouple member received in said bore for axial movement relative to said body member, said thermocouple member having a hot junction end positioned adjacent said first end of said body member, said second end of said body member having an enlarged diameter recess therein, gasket means positioned in said recess around said thermocouple member, and adapter mEans attached to said second end of said body member and biasing against said gasket means and holding said gasket means in sealing engagement around said thermocouple member and against the bottom of said recess.

Claim 10

An adjustable thermocouple assembly comprising; and elongated body member having a longitudinal bore therethrough and first and second ends, an elongated thermocouple member received in said bore for axial movement relative to said body member, said thermocouple member having a hot junction end positioned adjacent said first end of said body member, said second end of said body member having an enlarged diameter recess therein, gasket means positioned in said recess around said thermocouple member, and adapter mEans attached to said second end of said body member and biasing against said gasket means and holding said gasket means in sealing engagement around said thermocouple member and against the bottom of said recess.

Claim 11

The device of claim 8 and further including cooperating adjustment means on said thermocouple member and said adapter means for selectively moving said thermocouple member axially relative to said body member to position said hot junction end at different distances from said first end of said body member outside of said bore.

Claim 12

The device of claim 9 wherein said cooperating adjustment means includes knob means rotatably attached to said thermocouple member in a fixed axial position relative to said thermocouple member, and interengaged screw threads on said knob means and said adapter means.

Claim 13

In a thermocouple member including an elongated cylindrical sheath having first and second end portions, a pair of wires of dissimilar material extending within said sheath, said wires being joined adjacent said first end portion of said sheath to define a hot junction end, insulating material in said sheath insulating said wires from said sheath, and a body member through which said sheath is slidably disposable the improvement comprising; knob means rotatably attached to said sheath between said first and second ends in a fixed axial position with respect to said sheath, said knob means having adjustment means thereon for cooperation with another adjustment means fixed with respect to said body member, said knob means including a gripping portion and a cylindrical portion extending from said gripping portion toward said hot junction end axially of said sheath, said cylindrical portion having screw threads formed thereon to define said adjustment means on said knob means, and said knob means including a cylindrical member extending from said gripping portion around said cylindrical portion in radially spaced relation to said cylindrical portion.

Claim 14

In a thermocouple member including an elongated cylindrical sheath having first and second end portions, a pair of wires of dissimilar material extending within said sheath, said wires being joined adjacent said first end portion of said sheath to define a hot junction end, insulating material in said sheath insulating said wires from said sheath, and a body member through which said sheath is slidably disposable the improvement comprising; knob means rotatably attached to said sheath between said first and second ends in a fixed axial position with respect to said sheath, said knob means having adjustment means thereon for cooperation with another adjustment means fixed with respect to said body member, said knob means including a gripping portion and a cylindrical portion extending from said gripping portion toward said hot junction end axially of said sheath, said cylindrical portion having screw threads formed thereon to define said adjustment means on said knob means, and said knob means including a cylindrical member extending from said gripping portion around said cylindrical portion in radially spaced relation to said cylindrical portion.

Claim 15

In a thermocouple member including an elongated cylindrical sheath having first and second end portions, a pair of wires of dissimilar material extending within said sheath, said wires being joined adjacent said first end portion of said sheath to define a hot junction end, insulating material in said sheath insulating said wires from said sheath, and a body member through which said sheath is slidably disposable the improvement comprising; knob means rotatably attached to said sheath between said first and second ends in a fixed axial position with respect to said sheath, said knob means having adjustment means thereon for cooperation with another adjustment means fixed with respect to said body member, said knob means including a gripping portion and a cylindrical portion extending from said gripping portion toward said hot junction end axially of said sheath, said cylindrical portion having screw threads formed thereon to define said adjustment means on said knob means, and said sheath having a pair of spaced-apart stops secured thereto, said knob means being positioned between said stops.

Claim 16

In a thermocouple member including an elongated cylindrical sheath having first and second end portions, a pair of wires of dissimilar material extending within said sheath, said wires being joined adjacent said first end portion of said sheath to define a hot junction end, insulating material in said sheath insulating said wires from said sheath, and a body member through which said sheath is slidably disposable the improvement comprising; knob means rotatably attached to said sheath between said first and second ends in a fixed axial position with respect to said sheath, said knob means having adjustment means thereon for cooperation with another adjustment means fixed with respect to said body member, said knob means including a gripping portion and a cylindrical portion extending from said gripping portion toward said hot junction end axially of said sheath, said cylindrical portion having screw threads formed thereon to define said adjustment means on said knob means, and said sheath having a pair of spaced-apart stops secured thereto, said knob means being positioned between said stops.
