ABSTRACT:
A digging bucket has a lip, a lip aperture with a forward surface, a digging component mounted on the lip, and a component retaining device. The device comprises a keeper wedge with protrusions bearing against the component and a wedge member interposed between the forward surface and the component. In the improvement, the keeper wedge has at least one angled face and the wedge member has a pair of angled faces, at least one of which bears against the angled face of the keeper wedge. The wedge member is retained in position by a tension bolt extending through the aperture. Several embodiments are disclosed with wedge members having one or two wedges to urge the keeper wedge (and thus the digging component) rearward tightly against the lip.
