ABSTRACT:
A radial-jaw chuck for lathes and like turning machines comprises a chuck body having a central jaw-tightening member, e.g. a sleeve, which by respective projections engages respective axially displaceable pins. The pins, in turn, are connected with chordal wedge bars by respective wedge mechanisms so that axial displacement of the pins shifts the wedge bars along the respective chords. The wedge bars, in addition, are connected with the respective chuck jaws by inclined-tooth arrangements so that the axial displacement of the tightening member causes radial displacement of the jaws.
