Abstract
Abstract A workpiece support including a generally horizontal upper surface. The support includes an integral vertically short cylindrical projection which extends above the upper surface and the projection has a pair of side-by-side wide and narrow upwardly opening slots or grooves formed therein with the opposite ends of the slots opening outwardly through opposite side portions of the cylindrical projection and the bottom wall surfaces of the slots coplanar with or spaced at least slightly above the upper surface of the support from which the projection extends. In addition, the bottom wall of each slot includes a vertically short upwardly projecting central rib which extends at least substantially the full length of the corresponding slot.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
186 words
A workpiece support including a body portion having upstanding opposite side edges and an upper surface, an elongated arcuate groove formed in said body portion and opening endwise outwardly through said side edges and laterally upwardly through said upper surface throughout its entire length, said groove being of a width at least slightly greater than the thickness of an expandable watchband and of a depth at least slightly less than the width of an expandable watchband, said groove including a bottom wall provided with a central upstanding and longitudinally extending rib, said rib being spaced at least slightly from the opposite side walls of said groove dividing at least the bottom of said groove into spaced parallel groove segments, a base member from which said body portion is supported and including a generally flat or planar upper surface above which said body portion projects, the bottom walls of said groove segments being elevated at least to the elevation of the upper surface of said base member, said body portion including side wall surfaces projecting upwardly from said base including remote portions thereof defining said side edges.
