Abstract
Abstract A taut band suspension system for an electrical measuring instrument including a taut band, an inner band anchor connected to an armature assembly and an outer band anchor connected to a frame member. The taut band is ''''welded'''' to tab portions formed integrally on each band anchor and located along the axis of rotation of the armature assembly. The taut band is thus welded along a portion of its length and directly along the axis of rotation of the armature assembly which it rotatably supports.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
In an electrical measuring instrument including a frame member, means for providing a magnetic field and an armature assembly, the improvement of means for suspending the armature assembly for rotation about an axis within the magnetic field comprising: a. a taut band; b. an inner band anchor including a flat plate connected to the armature assembly having an integral tab extending perpendicularly therefrom along the axis of rotation, one end of said taut band being bonded to said tab; and c. an outer band anchor connected to the frame member having an integral tab extending along the axis of rotation, the other end of said taut band being bonded to said tab.
Claim 2
Dependent Claim
112 words
In an electrical measuring instrument including a frame member, means for providing a magnetic field and an armature assembly, the improvement of means for suspending the armature assembly for rotation about an axis within the magnetic field comprising: a. a taut band; b. an inner band anchor including a flat plate connected to the armature assembly having an integral tab extending perpendicularly therefrom along the axis of rotation, one end of said taut band being bonded to said tab; and c. an outer band anchor connected to the frame member having an integral tab extending along the axis of rotation, the other end of said taut band being bonded to said tab.
Claim 3
Dependent Claim
39 words
An electrical measuring instrument as recited in claim 1 wherein said inner band anchor additionally comprises clamping means welded to said tab and said taut band whereby said taut band is clamped between said tab and said clamping means.
Claim 4
Dependent Claim
63 words
An electrical measuring instrument as recited in claim 2 wherein said inner band anchor clamping means comprises an integral extension of said tab having an aperture formed therein, said extension being bent about an axis transverse to said tab and substantially centered on said aperture, said taut band passing through said aperture and being clamped and welded to said tab and said extension.
Claim 5
Dependent Claim
25 words
An electrical measuring instrument as recited in claim 3 wherein portions of said tab and extension adjacent said taut band of said aperture are radiused.
Claim 6
Dependent Claim
43 words
An electrical measuring instrument as recited in claim 1 wherein said outer band anchor comprises a generally U-shaped member including a pair of leg portions and a generally curved connecting bight portion and said integral tab extends from one of said leg portions.
Claim 7
Dependent Claim
38 words
An electrical measuring instrument as recited in claim 5 wherein said outer band anchor additionally comprises clamping means bonded to said tab and said taut band whereby said taut band is clamped between said taB and clamping means.
Claim 8
Dependent Claim
66 words
An electrical measuring instrument as recited in claim 6 wherein said outer band anchor clamping means comprises an integral extension of said tab having a transversely extending notch formed therein, said extension being bent about an axis transverse to said tab and substantially centered on said notch, said taut band passing through said notch and being clamped and welded to said tab and said integral extension.
Claim 9
Dependent Claim
110 words
An electrical measuring instrument as recited in claim 1 additionally comprising a second taut band, a second inner band anchor, a second outer band anchor, and integral tabs on said second inner and outer band anchors aligned on the axis of armature rotation, said integral tabs being bonded to said second taut band at the ends thereof and along the axis of armature rotation, said first and second inner band anchors being connected to opposite sides of the armature assembly and said first and second outer band anchors being connected to the frame member whereby the armature assembly is suspended from the frame member for rotation in the magnetic field.
Claim 10
Dependent Claim
21 words
An electrical measuring instrument as recited in claim 8 wherein said second inner band anchor is insulated from the armature assembly.
