ABSTRACT:
A spool and wedge assembly for securing replaceable cutting teeth or cutting elements to the nose portions of earth moving buckets. The spool and wedge assembly comprises first and second parallel longitudinally extended spool elements, which are transversely displaced apart to engage the aligned side walls of the securing element receiving apertures, and, first and second wedge shaped elements. The wedge and spool elements are interconnected by a longitudinally disposed screw threaded bolt mechanism which is tightened to draw the first and second wedge elements together while forcing the first and second spool elements apart, such that the cutting teeth are locked in position.
