Abstract: In an excavation bucket, the nose of an adapter has two surfaces to take the horizontal loads and four surfaces to take the vertical loads. A pin holds and locks a tooth to the adapter. Projections on the pin engage sloping surfaces of the nose. A recess placed ahead of the nose of the adapter will become visible as the tooth erodes due to wear. A recess at the nose of the adapter indicates that the tooth has worn too much and, unless the tooth is replaced, will commence to cause wear of the adapter and adjacent parts. To attach the adapter to the lip of the excavation bucket, wedge members are joined together near one end thereof to form a wedge-shaped block insertable into a wedge-shaped space formed by a C-clamp surface and a slot in the lip. The block is forced into the space, and spring biased teeth carried by the lock box progressively enter and leave the recesses in the outer surface of the C-clamp. When the C-clamp is tight enough in the gap, the installation of the lock box is complete.
