Adjustable workpiece-holding system
First Claim
1. An adjustable workpiece-holding system comprising:
- at least one jaw member for applying pressure against a workpiece, said jaw member holding a plurality of finger elements extending lengthwise in parallel in a longitudinal direction of said jaw member, said finger elements having front ends thereof facing toward the workpiece and side surfaces thereof abutting in contact with those of respective, adjacent finger elements,wherein the side surfaces of the finger elements have serrations extending in parallel in a direction transverse to the longitudinal direction and being formed over a given length in the longitudinal direction of the side surfaces of said finger elements, said serrations being substantially uniform and symmetric with each other such that each finger element is selectively adjustable in lengthwise position relative to adjacent finger elements and is securely held in its lengthwise position by positive engagement of the serrations of its side surfaces with those of the adjacent finger elements to create an exact predetermined contour shape for retention of a workpiece,and wherein said serrations provide fast and easy reproduction of said exact contour shape.

Abstract
An adjustable workpiece holder has at least one jaw member holding a plurality of finger elements lengthwise in parallel therein. The finger elements have side surfaces with serrations formed over a given length thereof. The serrations allow the finger elements to be selectively adjustable in lengthwise position relative to adjacent finger elements, so that they can conform to the contour of the workpiece. The finger elements may have a total width that fits snugly within a recess or pocket of the jaw member. A releasable clamp applies firm lateral pressure to the finger elements to prevent any slippage. The jaw member may be part of a machining assembly or retrofitted to one or both sides of a standard milling or drill press vise. It may also be adapted for use in forming, stamping, bending, or shaping material, or for profiling or as a template for holding or positioning workpieces in other applications.

6. An adjustable contour-following system comprising:
-
at least one holder member adapted to be placed in contact with a given contour of a workpiece, said holder member holding a plurality of finger elements extending lengthwise in parallel in a longitudinal direction of said holder member, said finger elements having front ends thereof facing toward the workpiece and side surfaces thereof abutting in contact with those of respective, adjacent finger elements, wherein the side surfaces of the finger elements have serrations extending in parallel in a direction transverse to the longitudinal direction and being formed over a given length in the longitudinal direction of the side surfaces of said finger elements, said serrations being substantially uniform and symmetric with each other such that each finger element is selectively adjustable in lengthwise position relative to adjacent finger elements and is securely held in its lengthwise position by positive engagement of the serrations of its side surfaces with those of the adjacent finger elements to create an exact predetermined contour shape for retention of a workpiece, and wherein said serrations provide fast and easy reproduction of said exact contour shape. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
