Patent number: 5526592Abstract: A lip shroud system which requires no additional hardware to hold a lip shroud on the front lip of an excavation bucket. The front shroud is held by mating lugs to the adapter and to an adjacent tooth pinned to the adapter. The lip bottom is protected by a wear plate held on the front lip by the front shroud. The front shroud is out of engagement with the lip. Thus, even if the lip shroud should loosen, it does not cause wear on the lip. The front shroud wedges between adjacent parts of the adapter, sideways movement of the adapter is virtually eliminated. This greatly reduces the lip wear in the adapter area. The front lip of the assembly is protected by the front shroud which is locked in place by the teeth associated with the adapter for coupling the tooth to the bucket wherein no additional weight is added to the system because no additional hardware is required for connecting the shroud to the bucket, thereby minimizing costs.Type: GrantFiled: July 22, 1994Date of Patent: June 18, 1996Inventor: Robert S. Bierwith
