Abstract
Abstract A measuring feeler is incorporated in a bore of a workpiece by surrounding it with a filling material which is softer than that of the feeler and the workpiece and by applying a compressive pressure to the softer material to cause its plastic deformation and tight engagement with the bore of the workpiece and with the temperature feeler. The feeler is installed in the bore of the workpiece by orienting a counter member or rod at the end of the bore at which the feeler end is to be exposed, positioning the feeler end to engage the rod, applying the softer material around the rod and thereafter applying pressure to the softer material from the opposite end of the bore in the direction of the rod to tightly seal the feeler and the soft material in respect to the bore of the workpiece. The softer material surrounds the measuring feeler in the form of a sleeve having an outer jacket or dimension such that it bears tightly against the workpiece in the recesses or grooves thereof.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
60 words
An arrangement of a measuring feeler in a recess or bore of the workpiece, comprising a workpiece having a recess, a measuring feeler rod located within said recess, and a sleeve of a pressure deformable heat and current conductive material surrounding said measuring feeler rod and being compressibly deformed into sealing engagement with said measuring feeler rod and said workpiece.
Claim 2
Dependent Claim
60 words
An arrangement of a measuring feeler in a recess or bore of the workpiece, comprising a workpiece having a recess, a measuring feeler rod located within said recess, and a sleeve of a pressure deformable heat and current conductive material surrounding said measuring feeler rod and being compressibly deformed into sealing engagement with said measuring feeler rod and said workpiece.
Claim 3
Dependent Claim
42 words
An arrangement, according to claim 1, including a bushing surrounding said temperature feeler and having an inner end portion arranged in the bore overlying said sleeve said sleeve having an end flush with said feeler rod at the interior of said workpiece.
Claim 4
Dependent Claim
32 words
An arrangement, according to claim 4, wherein said workpiece comprises a combustion chamber having cooling channels therein said feeler rod being arranged with its end at the interior of said combustion chamber.
Claim 5
Dependent Claim
16 words
An arrangement according to claim 1, wherein said heat and current conductive material comprises a metal.
Claim 6
Dependent Claim
12 words
An arrangement according to claim 4, wherein said metal comprises annealed silver.
Claim 7
Independent Claim
78 words
A method of installing a measuring feeler within a bore or recess of a workpiece, comprising centering the measuring feeler within the recess or bore, applying a sleeve of a conductive material softer than the temperature feeler and the workpiece around the measuring feeler and within at least a portion of the recess or bore, and applying a deformable pressure to deform the softer material into force, current and heat-conducting engagement with the temperature feeler and the workpiece.
Claim 8
Independent Claim
78 words
A method of installing a measuring feeler within a bore or recess of a workpiece, comprising centering the measuring feeler within the recess or bore, applying a sleeve of a conductive material softer than the temperature feeler and the workpiece around the measuring feeler and within at least a portion of the recess or bore, and applying a deformable pressure to deform the softer material into force, current and heat-conducting engagement with the temperature feeler and the workpiece.
Claim 9
Dependent Claim
17 words
A method, according to claim 6, wherein the softer material which is employed is an annealed silver.
Claim 10
Dependent Claim
97 words
An arrangement of a measuring feeler in a bore or recess of workpiece, comprising a workpiece having a bore extending therethrough, a counter rod member positioned to close the bore at the measuring end thereof, a measuring feeler rod located within said recess, and a sleeve of a pressure deformable material surrounding said measuring feeler rod and being compressibly deformed into sealing engagement with said measuring feeler rod and said workpiece, said feeler rod being positioned against the surface of said rod member at the interior of the workpiece, said sleeve being deformed against said rod member.
Claim 11
Dependent Claim
97 words
An arrangement of a measuring feeler in a bore or recess of workpiece, comprising a workpiece having a bore extending therethrough, a counter rod member positioned to close the bore at the measuring end thereof, a measuring feeler rod located within said recess, and a sleeve of a pressure deformable material surrounding said measuring feeler rod and being compressibly deformed into sealing engagement with said measuring feeler rod and said workpiece, said feeler rod being positioned against the surface of said rod member at the interior of the workpiece, said sleeve being deformed against said rod member.
Claim 12
Independent Claim
148 words
A method of installing a measuring feeler within a bore of a workpiece having a bore extending through the wall thereof, comprising centering the measuring feeler within the bore, applying a sleeve of a conductive material softer than the temperature feeler and the workpiece around the measuring feeler and within at least a portion of the recess or bore, applying a deformable pressure to deform the softer material into force, current and heat-conducting engagement with the temperature feeler and the workpiece, arranging a counter member at the side of the bore at which the end of the measuring feeler is to be positioned, thereafter positioning the feeler member to cause engagement of the end thereof with the counter member, and applying pressure to the sleeve member on the side opposite to the counter member to cause it to deform into engagement with the workpiece and the temperature feeler.
Claim 13
Independent Claim
148 words
A method of installing a measuring feeler within a bore of a workpiece having a bore extending through the wall thereof, comprising centering the measuring feeler within the bore, applying a sleeve of a conductive material softer than the temperature feeler and the workpiece around the measuring feeler and within at least a portion of the recess or bore, applying a deformable pressure to deform the softer material into force, current and heat-conducting engagement with the temperature feeler and the workpiece, arranging a counter member at the side of the bore at which the end of the measuring feeler is to be positioned, thereafter positioning the feeler member to cause engagement of the end thereof with the counter member, and applying pressure to the sleeve member on the side opposite to the counter member to cause it to deform into engagement with the workpiece and the temperature feeler.
