Abstract
Abstract A circular temperature gauge includes tubing which encloses a temperature sensor and a housing which encloses a needle connected to the sensor and a dial connected to the housing. The housing is secured with respect to the tubing such that the housing can be rotated to calibrate the indicator needle with respect to the dial. A slip bezel is mounted on the periphery of the circular housing. The force required to rotate the bezel with respect to the housing is less than the force required to rotate the housing with respect to the tubing. This prevents a worker who is in the process of installing the gauge from inadvertently rotating the housing with respect to the tubing and substantially miscalibrating the gauge.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
132 words
A gauge, comprising: a sensor, an enclosure for said sensor, a circular housing rotatably connected to said enclosure, a dial disposed within said housing, an indicator needle positioned within said housing, said needle connected to and driven by said sensor, said housing requiring a first force to rotate said housing relative to said enclosure thereby rotating said dial relative to said needle, and a resilient slip bezel forcibly and detachably mounted on the periphery of said circular housing, said slip bezel having a plurality of spaced means coacting with a portion of said gauge and rotatable around the periphery of said housing in response to a second force which is less than said first force, wherein rotation of said slip bezel does not alter the relationship of said needle to said dial.
Claim 2
Dependent Claim
132 words
A gauge, comprising: a sensor, an enclosure for said sensor, a circular housing rotatably connected to said enclosure, a dial disposed within said housing, an indicator needle positioned within said housing, said needle connected to and driven by said sensor, said housing requiring a first force to rotate said housing relative to said enclosure thereby rotating said dial relative to said needle, and a resilient slip bezel forcibly and detachably mounted on the periphery of said circular housing, said slip bezel having a plurality of spaced means coacting with a portion of said gauge and rotatable around the periphery of said housing in response to a second force which is less than said first force, wherein rotation of said slip bezel does not alter the relationship of said needle to said dial.
Claim 3
Dependent Claim
15 words
A gauge as recited in claim 1 wherein said sensor is a bimetallic temperature sensor.
Claim 4
Dependent Claim
22 words
A gauge as recited in claim 1 wherein said enclosure is a tubular element closed at one end thereof opposite said housing.
Claim 5
Dependent Claim
38 words
A gauge as recited in claim 1 wherein said housing includes a clamp-on bezel extending around the periphery of said housing, said clamp-on bezel securing said dial within said housing and providing a mount for said slip bezel.
Claim 6
Dependent Claim
31 words
A gauge as recited in claim 4 wherein said housing includes a circular crystal for protecting said needle and said dial, said crystal secured to said housing by said clamp-on bezel.
Claim 7
Dependent Claim
16 words
A gauge as recited in claim 1 wherein said slip bezel includes an inwardly directed pointer.
Claim 8
Dependent Claim
28 words
A gauge as recited in claim 1 wherein said slip bezel is fabricated of a flexible material and includes tabs for providing a snap-fit to said circular housing.
Claim 9
Dependent Claim
141 words
A temperature gauge, comprising: an elongate temperature sensor, a tube closed at one end and housing said sensor, a circular housing rotatably connected to said tube, a circular dial disposed within said housing, an indicator needle positioned within said housing, said needle connected to and driven by said sensor, said housing requiring a first force to rotate said housing relative to said tube, thereby rotating said dial relative to said needle, and a flexible slip bezel having a plurality of tabs coacting with a portion of said gauge to detachably mount said slip bezel on the periphery of said circular housing, said slip bezel rotatable around the periphery of said housing in response to a second force which is less than said first force, wherein rotation of said slip bezel does not alter the relationship of said needle to said dial.
Claim 10
Dependent Claim
141 words
A temperature gauge, comprising: an elongate temperature sensor, a tube closed at one end and housing said sensor, a circular housing rotatably connected to said tube, a circular dial disposed within said housing, an indicator needle positioned within said housing, said needle connected to and driven by said sensor, said housing requiring a first force to rotate said housing relative to said tube, thereby rotating said dial relative to said needle, and a flexible slip bezel having a plurality of tabs coacting with a portion of said gauge to detachably mount said slip bezel on the periphery of said circular housing, said slip bezel rotatable around the periphery of said housing in response to a second force which is less than said first force, wherein rotation of said slip bezel does not alter the relationship of said needle to said dial.
Claim 11
Dependent Claim
21 words
A temperature gauge as recited in claim 8 wherein said tabs are equally spaced on the interior of said slip bezel.
Claim 12
Dependent Claim
17 words
A temperature gauge as recited in claim 8 wherein said slip bezel includes an inwardly directed pointer.
Claim 13
Dependent Claim
160 words
A gague, comprising: a sensor, a tubular element closed at open end thereof for enclosing said sensor, a circular housing rotatably connected to said tubular element opposite said closed end thereof, a clamp-on bezel extending around the periphery of said housing, a dial secured within said housing by said clamp-on bezel, an indicator needle positioned within said housing, said needle connected to and driven by said sensor, said housing requiring a first force to rotate said housing relative to said tubular element, thereby rotating said dial relative to said needle, and a slip bezel fabricated of a flexible material and having an inwardly directed pointer and spaced tabs that snap-fit to said clamp-on bezel around the periphery of said housing, said slip bezel rotatable around the periphery of said housing in response to a second force which is less than said first force, wherein rotation of said slip bezel does not alter the relationship of said needle to said dial.
Claim 14
Dependent Claim
160 words
A gague, comprising: a sensor, a tubular element closed at open end thereof for enclosing said sensor, a circular housing rotatably connected to said tubular element opposite said closed end thereof, a clamp-on bezel extending around the periphery of said housing, a dial secured within said housing by said clamp-on bezel, an indicator needle positioned within said housing, said needle connected to and driven by said sensor, said housing requiring a first force to rotate said housing relative to said tubular element, thereby rotating said dial relative to said needle, and a slip bezel fabricated of a flexible material and having an inwardly directed pointer and spaced tabs that snap-fit to said clamp-on bezel around the periphery of said housing, said slip bezel rotatable around the periphery of said housing in response to a second force which is less than said first force, wherein rotation of said slip bezel does not alter the relationship of said needle to said dial.
