Abstract:
A workpiece holder having a pair of separately adjustable jaws, comprising:(a) a frame having an interiorly disposed, substantially rectangular cavity and a longitudinal axis, said cavity bounded by first, second and third outer wall portions of said frame, all of said wall portions extending orthogonally from a base portion of said frame along longitudinal axes, and said first and third walls being parallel to each other;(b) a pair of workpiece engaging jaws each of substantially equal rectangular transverse cross section, the pair sized to slidingly fit side-by-side longitudinally within said cavity when disposed parallel to said longitudinal axis, an upper face of each jaw formed at a 45 degree angle and said pair of jaws oriented to provide a 90 degree V therebetween;(c) each jaw further having means for engaging a longitudinally oriented adjusting screw on a lower face, and a slotted locking screw channel extending transversely through its central region;(d) said base portion having a pair of longitudinally oriented threaded holes to carry a pair of threaded adjusting screws, each adjusting screw aligned to urge an associated jaw into longitudinally adjustable positions with respect to said base portions; and(e) said second wall portion having a pair of transversely oriented threaded holes to receive a pair of threaded locking screws, each locking screw aligned to urge an associated jaw into a frictional locking engagement with said second wall portion upon being routed through said jaw's associated locking screw channel.
