Patent ID: 8464444

Claim:
A connection for immovably securing an adapter for detachably carrying a replaceable digging tooth at its front end to a lip of an excavating container of excavating equipment, the adapter having an upper leg and a lower leg located proximate respective upper and lower surfaces of the lip, the connection comprising substantially aligned openings in the legs and the lip, engagement sections of the adapter legs traversing the opening in the lip proximate and forward of an aft end thereof, a pressure applying unit arranged inside the openings adapted to generate and release a generally horizontally acting force which draws the adapter and the lip towards each other, a stress member operatively coupled to the pressure applying unit which resiliently deforms relative to its relaxed shape when the stress member is subjected to the horizontally acting force, and a spacer configured to be inserted between the pressure applying unit and the openings while the horizontally acting force resiliently deforms the stress member, the spacer being further shaped so that upon a reduction or cessation of the horizontally acting force the spacer continues to maintain the stress member in a resiliently deformed state in which it draws the adapter and the lip towards each other.
