Resilient flex pin apparatus for excavating tooth point and adapter assemblies

Abstract From the Canadian patent

An improved resilient flex pin is provided for use in captively retaining an excavating tooth point on an adapter nose and is drivable into aligned openings formed in the tooth point and adapter nose. The flex pin includes an elongated rigid locking member having an elongated lateral recess formed therein. An elongated rigid wedge member is intersecured to the locking member by means of a spaced series of elastomeric segments positioned in the recess and, is laterally movable into the recess against the resilient resistance of the elastomeric segments. The wedge member has a longitudinally intermediate portion which is engageable by a forward side surface of the adapter nose opening and is …
