Abstract
Abstract An electric gage driving a pointer has an extended spindle so that the gage movement can be substantially spaced from the pointer. The gage includes a spindle, an armature driving the spindle, a bobbin supporting a bearing for the spindle and electrical coils around the bobbin. An outrigger support remote from the bobbin and adjacent the pointer holds another spindle bearing which may be misaligned with the bobbin. The bearing on the bobbin accommodates the misaligned spindle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
An electric gage mechanism comprising; a gage movement having a bobbin and an armature within the bobbin, a pointer located remotely from the armature, an extended spindle for driving the pointer and having sufficient length to extend from the armature to the pointer, first and second bearings between the pointer and the armature, an outrigger adjacent the pointer, the first bearing being placed in the outrigger for rotatably supporting the spindle, the first bearing being subject to misalignment with the bobbin, and the second bearing being placed in the bobbin for supporting the spindle for rotary movement, the second bearing being shaped to accommodate misalignment of the first bearing.
Claim 2
Dependent Claim
109 words
An electric gage mechanism comprising; a gage movement having a bobbin and an armature within the bobbin, a pointer located remotely from the armature, an extended spindle for driving the pointer and having sufficient length to extend from the armature to the pointer, first and second bearings between the pointer and the armature, an outrigger adjacent the pointer, the first bearing being placed in the outrigger for rotatably supporting the spindle, the first bearing being subject to misalignment with the bobbin, and the second bearing being placed in the bobbin for supporting the spindle for rotary movement, the second bearing being shaped to accommodate misalignment of the first bearing.
Claim 3
Dependent Claim
131 words
An electric gage mechanism comprising; a gage movement having a control winding, a bobbin supporting the winding, a permanent magnet armature within the bobbin and a spindle driven by the armature, a pointer located remotely from the armature and mounted on the distal end of the spindle, a support for the gage movement, an outrigger mounted on the support, first and second bearings between the pointer and the armature, the first bearing being mounted on the outrigger near the pointer for rotatably supporting the spindle, the first bearing being subject to misalignment with the bobbin, and the bobbin defining a cavity containing a damping fluid and having a single aperture comprising the second bearing, the aperture having an approximately venturi-shaped throat for sealingly engaging the spindle and for allowing spindle misalignment.
