ABSTRACT:
The invention is an improvement in a tooth assembly used with excavating and digging buckets such as those found in draglines, backhoes and the like. Such tooth assemblies include a top portion (such as a wear cap), a nose protruding beyond the portion and a digging tip. The tip has high-hardness upper and lower exterior wear surfaces and a sharp-edged tip end for biting into earth, mineral and rock. Either embodiment of the improved assembly involves mounting parts (a tip or tip and sleeve) directly on the nose. In one improved assembly, a sleeve is interposed between the tip and the portion and includes high-hardness wear surfaces extending between tip and portion. The tooth and sleeve cooperate to substantially entirely shroud the nose. In another version having no sleeve, the tip includes high-hardness active digging surfaces extending substantially entirely rather than only partially between the portion and the tip end. The tooth entirely shrouds the nose rather than being attached to the nose by a separate tip holder. With the improved arrangements, the tip and sleeve (or tip alone) comprise the primary replaceable parts and the nose is protected in that it is between high-hardness surfaces.
