Abstract:
A wedge assembly for placement into a tapered hole for securing a tooth adapter to an excavation bucket with a C-clamp, the adapter, the bucket and the C-clamp forming a through hole including a tapered section which is angularly inclined relative to an axis of the hole, the wedge assembly comprising:an elongated main body having longitudinal first and second end sections and a midsection therebetween, the midsection having a transverse extent greater than a transverse extent of the end sections, and a face which is angularly inclined relative to a longitudinal extent of the body, extends over the first end section and at least a portion of the midsection, and terminates in the midsection at a shoulder oriented transversely to the longitudinal extent of the body and facing towards the first end section;a lock member in surface contact with the face, engaging the shoulder, and having a wedging surface for engaging the tapered section of the through hole, the lock member extending from the body in a transverse direction past the transverse extent of the midsection of the body and defining an impact surface in a vicinity of the shoulder which generally faces towards the second end; anda shear member securing the lock member to the body so that the lock member engages the face and the shoulder of the body, the shear member being formed so that it can be sheared off to permit the separation of the lock member from the body when the wedge assembly is disposed in the hole by applying a force to the impact surface of the lock member in a direction towards the first end section.
