Abstract
Abstract Apparatus for micropositioning an operational member and a workpiece platform comprises either a fixed platform or a fixed operational member. In the fixed platform, four arms, each arm comprising a pair of substantially rigid coextensive resilient sections, extend between support posts affixed to the workpiece platform and a suspended operational member to angularly and translationally position the operational member relative to the workpiece platform by varying the extending length of each arm from the support posts by varying the spacing between each pair of resilient sections proximate their midpoints. In the apparatus for aligning the workpiece platform relative to the operational member, the platform has adjustable legs for angularly positioning the platform relative to the operational member and substantially rigid resilient translating legs fixed relative to the operational member, engaging the workpiece platform for translating the platform relative to the operational member by varying the length of each leg extending between its fixed point and the platform.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
95 words
An apparatus for positioning in space a member relative to a base, comprising: at least two adjustable length arms longitudinally extending from the member to means for supporting said adjustable length arms affixed to the base, each adjustable length arm having two coextensive sections and means for engaging said coextensive sections to said member and said means for supporting and further including means for adjusting disposed between each pair of coextensive sections to vary the distance between said pair of coextensive sections and thereby vary the distance between the member and said means for supporting.
Claim 2
Independent Claim
95 words
An apparatus for positioning in space a member relative to a base, comprising: at least two adjustable length arms longitudinally extending from the member to means for supporting said adjustable length arms affixed to the base, each adjustable length arm having two coextensive sections and means for engaging said coextensive sections to said member and said means for supporting and further including means for adjusting disposed between each pair of coextensive sections to vary the distance between said pair of coextensive sections and thereby vary the distance between the member and said means for supporting.
Claim 3
Dependent Claim
39 words
The apparatus as defined in claim 1, wherein means for adjusting to vary the distance between the coextensive sections comprises an adjuster threadably engaged with one of the coextensive sections and disposed for bearing against the other coextensive section.
Claim 4
Dependent Claim
13 words
The apparatus as defined in claim 1, wherein each coextensive section is resilient.
Claim 5
Dependent Claim
22 words
The apparatus as defined in claim 1, wherein one arm each is engaged to the member at opposite ends of the member.
Claim 6
Dependent Claim
36 words
The apparatus as defined in claim 1, further including a third adjustable length arm engaging the member and extending substantially transversely therefrom to further means for supporting said third adjustable length arm affixed to the base.
Claim 7
Dependent Claim
42 words
The apparatus, as defined in claim 5, wherein the third adjustable length arm comprises two coextensive sections longitudinally extending from the member to said means for supporting and means for engaging said coextensive sections to said member and said means for supporting.
Claim 8
Dependent Claim
37 words
The apparatus, as defined in claim 6, further comprising means for adjusting disposed between each pair of coextensive sections to vary the distance therebetween and thereby vary the distance between the member and the means for supporting.
Claim 9
Dependent Claim
35 words
The apparatus, as defined in claim 7, wherein the means for adjusting disposed between the coextensive sections comprises an adjuster threadably engaged with one of the sections and disposed for bearing against the other section.
Claim 10
Independent Claim
93 words
An apparatus for positioning in space a member relative to a base, comprising; four arms longitudinally extending from the member to means for supporting said arms affixed to the base, each arm having a pair of coextensive sections including adjustable portions and means for engaging said coextensive sections to said member and said means for supporting and further including means for adjusting disposed between each pair of longitudinally extending sections to vary the distance between said pair of coextensive sections and thereby vary the distance between the member and said means for supporting.
Claim 11
Independent Claim
93 words
An apparatus for positioning in space a member relative to a base, comprising; four arms longitudinally extending from the member to means for supporting said arms affixed to the base, each arm having a pair of coextensive sections including adjustable portions and means for engaging said coextensive sections to said member and said means for supporting and further including means for adjusting disposed between each pair of longitudinally extending sections to vary the distance between said pair of coextensive sections and thereby vary the distance between the member and said means for supporting.
Claim 12
Dependent Claim
13 words
The apparatus as defined in claim 9, wherein the coextensive sections are resilient.
Claim 13
Dependent Claim
35 words
The apparatus as defined in claim 10, wherein the means to vary the distance between the sections comprises an adjuster threadably engaged with one of the sections and disposed for bearing against the other section.
