    Patent number: 5784813
    Abstract: A spool and wedge assembly for attaching a replaceable implement to the nose of an earthworking bucket has a spool 12 and wedge 10 with ramp surfaces 22, 40 causing lateral expansion of the unit upon relative axial movement, and bolting mechanism 14, 16 for drawing the spool and wedge together so that the wedge pushes forwardly against the bucket nose and the spool pushes forward against the implement. A disengagement tool 78 acts between the wedge and the bolt 14 to force disengagement of the ramp surfaces for removal.
