ABSTRACT:
The invention relates to an assembly of ground engaging tool components which are attachable to the lip of a bucket of an earth moving machine. The assembly of tool components comprises a nosepiece attachable to the lip of the bucket, an adaptor attachable to the nosepiece and a tip attachable to the adaptor. The components are attachable to one another by spigot and socket arrangements, the relevant spigot in each case defining two opposed tapered faces and a pair of side faces spacing the tapered faces from one another, at least one of the side faces of the spigot defining a groove with opposed side walls which are tapered in an opposite sense to the taper on the opposed tapered faces. Similarly, the relevant socket in each case has opposed internal tapered faces which correspond to the tapered faces on the spigot, and a pair of internal side faces spacing the internal tapered faces from one another, at least one of the internal side faces including a wedge having opposed side walls which are tapered in an opposite sense to the taper on the opposed internal tapered faces of the socket and which correspond to the taper on the opposed side walls of the groove. Each spigot is arranged to fit within a corresponding socket so that the wedge lies within the groove, is movable along the length of the groove, and can be wedged therein when the two opposed tapered faces on the spigot mate with the two opposed internal tapered faces in the socket.
