Abstract
Abstract Temperature sensing apparatus in which a temperature responsive member is maintained in a self aligning position with a predetermined force on the surface of a heated rotating or stationary roll surface. Support is given on a crowned pin member which enables the temperature responsive member to rock perpendicular and parallel to the heated roll axis. This rocking action assures self alignment of the member with the roll surface. Also a counterweight is used to impart a predetermined moment about a second axis between the member and roll surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
Apparatus for sensing the surface temperature of a heated roll comprising temperature responsive means, thermally insulating first support means for supporting said temperature responsive means, a thermally conductive cap member positioned to encompass the end of said thermally responsive means and arranged as an extension of said first support means, second support meaNs connected to said first support means and pivotally mounted by a pin member on a first axis to position said cap member into contact with the surface of a heated roll, said pin member received in said first support means and being of a crowned shape, and said first support means having a shape complementary to said crown shaped pin member so as to effect a rocking action of said first support means perpendicular and parallel to the heated roll axis.
Claim 2
Dependent Claim
134 words
Apparatus for sensing the surface temperature of a heated roll comprising temperature responsive means, thermally insulating first support means for supporting said temperature responsive means, a thermally conductive cap member positioned to encompass the end of said thermally responsive means and arranged as an extension of said first support means, second support meaNs connected to said first support means and pivotally mounted by a pin member on a first axis to position said cap member into contact with the surface of a heated roll, said pin member received in said first support means and being of a crowned shape, and said first support means having a shape complementary to said crown shaped pin member so as to effect a rocking action of said first support means perpendicular and parallel to the heated roll axis.
Claim 3
Dependent Claim
25 words
Apparatus according to claim 1 wherein said conductive cap member is formed with a curved surface to closely fit the surface of the heated roll.
Claim 4
Dependent Claim
34 words
Apparatus according to claim 1 wherein said second support means includes a member having weighted portion spaced from said first axis to effect a moment urging said cap member against said heated roll surface.
Claim 5
Dependent Claim
13 words
Apparatus according to claim 1 wherein said heated roll is mounted for rotation.
Claim 6
Dependent Claim
31 words
Apparatus according to claim 4 wherein the distance between the pin member and conductive cap is sufficiently small to prevent moments created by frictional forces generated by rotation of the roll.
