ABSTRACT:
Tooth assemblies having a tip with ears extending rearwardly therefrom to mate with corresponding slots in an adapter are normally utilized in order to aid in the transfer of forces from the tip to the adapter. Since the forces being directed to the tip are normally applied in various directions and of varying magnitudes, the ears extending from the tip may be subjected to forces attempting to pry them outwardly, thus, subjecting them to the possibility of breakage. In the subject arrangement, a tip includes a pair of opposed ears each having a pair of opposed edge surfaces that are angled one relative to the other. The pair of opposed ears of the tip mates with a pair of corresponding opposed slots defined in an adapter. The pair of opposed slots in the adapter likewise has a pair of opposed edge surfaces angled with respect to one another and are in confronting mating relationship with the pair of opposed edge surfaces of the pair of opposed ears. This inhibits any outward movement of the pair of opposed ears with respect to the adapter.
