ABSTRACT:
A corner tooth is useful, for example, on construction equipment buckets to protect the sidewalls from abrasive wear which normally results from continued contact with the ground. In order to protect the sidewall, others use elements secured directly to the sidewall or various forms of specialized teeth mounted on the corner. Many of these specialized teeth inhibit the tooth's ability to penetrate the ground. The present corner tooth provides the protection for the sidewall while still maintaining good strength and penetration. This is due to a single flat member being oriented vertically with respect to the normal working position of the tooth and a single reinforcement rib extending perpendicular to the flat member. Furthermore, since the tooth is symmetrical about the second plane and the rib is located along the second plane the tooth can be used on either corner. This eliminates the need to manufacture and stock an extra part of a different design. Furthermore, once the part is installed, it remains in the same location for its entire useful life thus eliminating down time to change the tooth from one corner to the other.
