ABSTRACT:
The magnetic chuck disclosed herein is of the interlocking finger type and substantial components thereof are fabricated by making parallel oblique cuts in conventional bar stock thereby to generate a succession of parallelogram-shaped pieces. A series of the parallelogram pieces are assembled with alternate pieces being reversed so that they overlap only over a common triangular area with adjacent parallelogram pieces being separated by interleaved triangular spacers. The projecting fingers provided by such an assembly may be then mated with other similar or half-similar pole-piece units to form an interlock magnetic chuck top plate.
