ABSTRACT:
An excavation digging tooth locking device is disclosed for frictionally maintaining a digging tooth in a female reception pocket in matingly wedged relation. The locking device is a sliced section of an extruded member compressively wedged into and filling a varying dimensioned gap between the tooth and the pocket. The locking device has a tubular portion with a slit across its longitudinal dimension and a pair of divergent wing portions extending from the opposing faces of the slit. The wing portions have tapered distal ends of reduced cross section. The interface of the wing portions and the tubular portion have enlarged cross sections. The inner perimeter of the tubular portion engages a reduced end bight section of the inner tooth wedge portion, the opposing faces of the slit engage the deepest sections of recessed detents adjacent the bight section, and the wing portions engage the tapering shallower sections of the detents.
