Abstract
Abstract In a gauge, a case assembly and measuring assembly movable as a unit into and out of the case assembly. The case assembly includes a stem portion adapted to be secured in gauging position, a dial-receiving portion adapted to be secured in readout position, and angular joint means adjustably securing the stem portion to the dial portion. The measuring assembly includes a bimetallic helix, a dial, a pointer and means including torque springs for moving the pointer over the dial when the helix is subjected to temperature changes. The measuring assembly when moved into the case assembly positions the helix in the stem portion, the torque springs extending through the angular joint and the dial and pointer in the dial-receiving portion, and a gear for revolving the measuring assembly to reposition the pointer on the dial.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
In a gauge, a case assembly including an elongated stem portion adapted to be secured in gauging position, an elongated dial-receiving portion, and angular joint means adjustably securing the stem portion to the dial-receiving portion, and an interconnected measuring assembly including interconnected elements comprising a bimetallic helix, a dial, a pointer, and means including torque springs for moving the pointer over the dial when the helix is subjected to temperature changes, the improvement comprising the interconnected elements of the measuring assembly being movable as a unit into and out of the case assembly to position the helix in the stem portion, and to position the torque springs extending through the angular joint, and the dial and pointer in the dial-receiving portion, and means releasably holding the measuring assembly in the case assembly.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
61 words
The combination defined in claim 1 wherein that portion of the measuring assembly extending into the stem portion of the case assembly is free to be suspended from the dial portion therein so that proper locus of rotation of the torque springs is achieved regardless of the selected angle connecting the dial-receiving portion to the stem portion of the case assembly.
Claim 4
Dependent Claim
61 words
The combination defined in claim 1 wherein the angular joint means comprises two stamped sheet metal halves forming a hollow ball joint with interlocking tongue and groove edges, a gasket between the edges, and a threaded ring securing the edges together against the gasket in any selected angular relation between the dial-receiving portion and the stem portion of the case assembly.
Claim 5
Dependent Claim
50 words
The combination defined in claim 1 wherein the dial-receiving portion includes a one-piece case having a circular shelf receiving a cover glass for the scale, the shelf having a groove adjacent to it, and a retainer ring removably received in the groove for holding the cover glass on the case.
Claim 6
Dependent Claim
36 words
The combination defined in claim 1 wherein adjusting means, accessable from both the front and the back of the dial-receiving portion, are provided for zeroing in the pointer on the dial fixed in the dial-receiving portion.
Claim 7
Dependent Claim
33 words
The combination defined in claim 1 wherein the means releasably holding the measuring assembly in the case assembly are screw means extending through the dial into the dial-receiving portion of the case assembly.
