Abstract
A digging tooth assembly for an excavating machine including a digging tooth having a resilient housing for mounting the tooth to the forward end of a digging tooth shank. A wedge-shaped projection or retaining member is mounted to the top surface of the shank for locking engagement within a cut-out or socket formed in the housing for mounting the digging tooth. The digging tooth is held on the tip of the shank by the locking coaction between the wedge-shaped projection and cut-out and the resiliency of the housing. The top surface of the digging tooth abuts against the flat bottom surface of the shank such that impact forces are transmitted through the resilient digging tooth housing to the shank thereby providing the digging tooth with increased flexibility and longer wear life. The present construction provides for vertical cutting action by the digging tooth shank and horizontal cutting action by the digging tooth for improved loosening of the earth being excavated.
