Abstract
Abstract A tool positioner has a main support defining a pair of main pivot axes andncluding a guide. Respective main cranks have inner ends pivoted at the main pivot axes on a support and outer ends pivoted to ends of respective links whose other ends are pivoted on a tool holder. This holder has an elongated stem longitudinally displaceable in the guide and carries a tool which can pivot about the axis of the stem and about another axis perpendicular thereto. The two cranks can be displaced independently of each other for swinging of the tool holder about either of the main pivot axes or for displacing it along the axis of the stem.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
91 words
A positioner comprising: a main support defining a pair of main pivot axes and carrying a guide; respective main cranks having inner ends pivoted at said main pivot axes on said support and outer ends; respective links having respective one ends pivoted on said outer ends of said cranks and having other ends; a holder pivoted on said other ends of said links and having an elongated stem longitudinally displaceable in said guide; and respective means for pivoting said main cranks on said main support about the respective main pivot axes.
Claim 2
Dependent Claim
91 words
A positioner comprising: a main support defining a pair of main pivot axes and carrying a guide; respective main cranks having inner ends pivoted at said main pivot axes on said support and outer ends; respective links having respective one ends pivoted on said outer ends of said cranks and having other ends; a holder pivoted on said other ends of said links and having an elongated stem longitudinally displaceable in said guide; and respective means for pivoting said main cranks on said main support about the respective main pivot axes.
Claim 3
Dependent Claim
15 words
The positioner defined in claim 1 wherein said main axis are closely adjacent said guide.
Claim 4
Dependent Claim
19 words
The positioner defined in claim 2 wherein said stem defines a longitudinal axis generally angularly equispaced between said links.
Claim 5
Dependent Claim
14 words
The positioner defined in claim 3 wherein said guide is fixed on said support.
Claim 6
Dependent Claim
26 words
The positioner defined in claim 4 wherein said main axes coincide and said guide is an eye surrounding said stem and lying on said main axes.
Claim 7
Dependent Claim
20 words
The positioner defined in claim 1, further comprising brake means for inhibiting rotation of said cranks about said main axes.
Claim 8
Dependent Claim
58 words
The positioner defined in claim 1, further comprising a tool on said holder; means on said holder for pivoting said tool on said holder about a first axis passing through said holder; and means on said holder for pivoting said tool on said holder about a second axis transverse to said first axis and passing through said holder.
Claim 9
Dependent Claim
15 words
The positioner defined in claim 1 wherein said main axis generally symmetrically flank said guide.
Claim 10
Dependent Claim
20 words
The positioner defined in claim 1, further comprising means for pivoting said holder about an axis passing through said guide.
Claim 11
Dependent Claim
45 words
The positioner defined in claim 1 further comprising means fixed on said links and connected via said links and said cranks with said support for displacement of said guide along an axis fixed with respect to said support and halving the angle between the links.
Claim 12
Dependent Claim
28 words
The positioner defined in claim 1 wherein said guide and said stem include longitudinally extending and interfitting guide formations for sliding of said stem longitudinally in said guide.
Claim 13
Dependent Claim
16 words
The positioner defined in claim 1 wherein said links are L-shaped and concave toward each other.
Claim 14
Dependent Claim
30 words
The positioner defined in claim 1 wherein said means for pivoting said main cranks operate independently of each other and can each pivot the respective crank in either angular direction.
