Abstract
Improvements in digging apparatus, and in particular the lip and teeth of an excavating bucket for a backhoe machine. The bucket has spaced sides attached to a rear wall and a flat bottom which curves towards the rear wall. The sides and rear are joined to the bottom, and the bucket opening has a periphery defined by the upper edge portion of the rear wall, sides, and the forward edge of the teeth. The marginal, forward end of the bottom is in the form of a specially constructed bucket lip. A plurality of digging teeth are mounted individually to shanks formed at the forward end of the lip. The teeth are arranged respective to one another to provide a continuous cutting edge from one to the other side of the bucket, and the teeth are attached to the bucket lip. The geometrical configuration of the digging teeth, the bucket design, and the tooth distribution pattern increases the digging efficiency and provides a smooth excavated surface. The bucket lip transfers digging loads from the teeth into the backhoe dipper stick in an improved manner.
