Lock system for excavating tooth point and adapter

摘要

A lock system removably connects an earthengaging tooth point to an adapter. The lock system is particularly suited to tooth points for large excavating buckets, such as dragline buckets. The forward-extending nose of the adapter fits within the rear-facing socket of the tooth point. Ears extend back from the tooth point on both sides of the adapter and define apertures adapted to receive pins. A hole in the adapter is also adapted to receive the pins. The pins extend through the apertures and into the hole, thus fixedly connecting the tooth point to the adapter. To remove the tooth point, both pins can be driven into the adapter hole and housed there concurrently. The tooth point can then be removed and the pins later driven out of the hole.
