  • Patent number: 6446368
    Abstract: When added, the inclined plane (22) becomes the earth engaging tool. It is a robust, one piece, durable metal slope. Its leading edge is optionally pointed, narrowed, and thickened for use in consolidated and abrasive earth. Its leading edge fractures and cleaves as it up lifts excavated earth above and beyond its attachment to the implement (28). Working more than one inclined plane (22) in unison and arranged to bridge cleave, results in little to no abrasion to the implement (28), superior excavation performance, and excellent staying.

  • Patent number: 5553409
    Abstract: A wear protector system for shielding the leading edge of an earthmoving implement such as a loading bucket includes an arrangement of shrouds which cover the leading edge between the laterally spaced digger teeth. Each shroud has a nose portion that wraps around the leading edge and a rearwardly extending tail portion having an abutment surface that engages an undercut abutment surface of an anchor block that is welded to the bucket. The complementary abutment surfaces retain the tail portion from moving upwardly away from the bucket surface, whereas the shroud is retained from movement forwardly out of engagement with the lip by use of a cotter pin extending transversely through a passage that is formed partially in the tail of the shroud and partially in the anchor.

  • Patent number: 5526592
    Abstract: 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.
