Abstract
Abstract A work supporting plate for a machine tool is pivotally mounted between two normally fixed base arms and two swinging arms, the plate and arms being connected by a common pivot. A segment on each swinging arm has a row of uniformly spaced bores in an arc about the pivot axis for coarse adjustment of the angular plate portion in integral multiples of 1*, and a threaded abutment on each swinging arm permits the swinging arms with the plate to be finely adjusted relative to the base arms.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
219 words
An adjustable angle plate arrangement comprising, in combination: a. base means defining a reference plane; b. a work supporting member defining a supporting surface; c. pivot means having an axis parallel to said reference plane and securing one portion of said member to said base means for angular movement of said surface and for arcuate movement of another portion of said member spaced from said one portion about said axis; d. swinging means mounted on said base means for swinging movement about said axis and formed with a plurality of bores spaced from each other along a circular arc centered in said axis; e. fastening means engageable with said member and with each of said bores for fastening said other portion to said swinging means in respective angular positions relative to said swinging means; f. cooperating abutment means on said swinging means and on said base means respectively, said abutment means engaging each other in a point spaced from said axis during said swinging movement, said swinging means and said base means constituting respective carriers associated with said abutment means; and g. adjusting means for adjusting the position of one said abutment means on the associated carrier toward and away from said point in a direction substantially tangential relative to a circle through said point centered in said axis.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
An arrangement as set forth in claim 1, wherein said bores are uniformly spaced along said arc.
Claim 4
Dependent Claim
21 words
An arrangement as set forth in claim 2, wherein the uniform spacing of said bores is an integral multiple of 1*.
Claim 5
Dependent Claim
45 words
An arrangement as set forth in claim 1, wherein said pivot means secure said work supporting member to said base means for angular movement toward and away from a position in which said surfaces is parallel to said reference plane, the surface being substantially flat.
Claim 6
Dependent Claim
25 words
An arrangement as set forth in claim l, further comprising indicator means indicating the position of said one abutment means relative to the associated carrier.
Claim 7
Dependent Claim
29 words
An arrangement as set forth in claim 5, wherein said one abutment means is threadedly movable on said associated carrier about an axis extending in said substantially tangential direction.
Claim 8
Dependent Claim
132 words
An arrangement as set forth in claim 1, wherein said swinging means include a pair of elongated swinging arms, and said base means include a pair of elongated base arms, said work supporting member being releasably secured to respective longitudinal end poRtions of said arms by said pivot means and axially interposed between the members of each pair, said swinging arms being each formed with a plurality of said bores uniformly spaced along respective circular arcs of the same radius about said axis, said fastening means include two releasable fastening members respectively engageable with the bores of each swinging arm and with said work supporting member, and said abutment means include two abutment members respectively adjustable on said swinging arms in said substantially tangential direction and engageable with respective associated base arms.
Claim 9
Dependent Claim
42 words
An arrangement as set forth in claim 7, wherein said adjusting means include a micrometer screw on each swinging arm and indicator means for indicating the angular position of said screw, and said abutment members are respective anvils on said micrometer screws.
Claim 10
Dependent Claim
44 words
An arrangement as set forth in claim 7, further comprising two dial gages on said swinging arms, said abutment members being respective anvils of said gages, and said adjustment means including threaded members on said swinging arms abuttingly engageable with said base arms respectively.
Claim 11
Dependent Claim
119 words
An arrangement as set forth in claim 7, wherein the uniform spacing of said bores in said swinging arms is equal to an integral multiple of 1* of said arcs, the arrangement further including a gage block having a plurality of pairs of parallel surfaces and adapted to be interposed between each of said abutment members and the associated base arm in a plurality of different positions in which the parallel surfaces of respective pairs of parallel surfaces simultaneously engage said abutment member and the associated base arm, the angular positions of said swinging arm relative to the associated base arm differing by an integral number of degrees from each other in said different positions of said gage block.
