Patent number: 7121023Abstract: A rotatable connector pin assembly is disposed within an opening in an adapter nose, with opposite ends of the pin portion of the assembly extending outwardly beyond opposite sides of the adapter nose in axially fixed orientations relative thereto, and is used to captively and releasably retain a replaceable excavating tooth point on the nose. The configuration of the opposite pin ends permits the overall pin assembly to remain in the adapter nose during removal of the point and replacement thereof, with the pin being rotatable between a first orientation in which its ends permit removal of a point from the nose, or installation of a point on the nose, and a second orientation in which the opposite pin ends block removal of the point from the adapter nose.Type: GrantFiled: November 25, 2003Date of Patent: October 17, 2006Assignee: Hensley Industries, Inc.Inventors: Howard W. Robinson, Wayne A. Shamblin, Bruce L. Hart
