Abstract
A loader bucket comprises a pair of laterally spaced end walls and a cutting edge secured forwardly on a bottom wall of the bucket, between the end walls. A corner tooth assembly is detachably mounted on each of the end walls, adjacent to the cutting edge, and comprises an adapter having a forwardly extending adapter portion and an earthworking tip detachably mounted on the adapter portion. The adapter further comprises outer and inner mounting portions straddling the end wall and secured thereto by a single bolt extending transversely therethrough. In a first embodiment of this invention, a pair of first force transmitting surfaces are formed rearwardly on the adapter portion to abut a flat forward edge of the end wall and a bevelled surface of the cutting edge, respectively. A pair of longitudinally spaced second force transmitting surfaces are formed on a bottom portion of the adapter, secured to the outer portion thereof, to abut the underside of the cutting edge. A third force transmitting surface is formed on an underside of the inner portion of the adapter to abut a bearing pad formed integrally on the end wall of the loader bucket. In a second embodiment of this invention, a single force transmitting surface formed on the adapter portion to abut a forward edge of the cutting edge and the adapter portion is maintained out of contact with respect to the forward edge of the end wall.
