REPLACEABLE TOOTH ASSEMBLY

摘要

A replacable tooth assembly including a tooth formed with a conical interior opening and flanges extending from the base of the opening. The conical opening is applied to a conical adaptor nose and the flanges hold the tooth against rotation on the nose by coaction with the base of the adaptor. A key in the nose extends into slots in the flanges to lock the tooth on the nose. Limit surfaces of the key coact with surfaces of the tooth adjacent the tooth slots to prevent inadvertent removal of the key except through forcible movement of the key laterally and axially of the nose.
