Patent ID: 7997017

Claim:
A wear assembly for attachment to a lip of an excavating bucket wherein the lip has an inner surface, an outer surface and at least one through-hole extending through the lip, the through-hole opening in each of the inner and outer surfaces and having a shoulder defined between the inner and outer surfaces, the wear assembly comprising: a wear member having a front end to contact materials to be gathered into the bucket during excavating, an outer leg along the outer surface of the lip, and an inner leg to extend along the inner surface of the lip, the inner leg including a hole that generally aligns with the through-hole in the lip when the wear member is placed on the lip; a spool received into the hole in the inner leg of the wear member and the through-hole in the lip, the spool including a body, a lower arm projecting rearwardly from the body to contact the shoulder in the through-hole of the lip, and a pair of upper arms each projecting laterally from the body to contact the inner leg of the wear member; and a wedge received into the hole in the inner leg of the wear member and the through-hole in the lip forward of the spool, the wedge including a leading end and a trailing end, an external surface that tapers toward the leading end, and a longitudinal axis extending from the trailing end to the leading end, the wedge being axially movable in the through-hole such that movement of the wedge in a downward direction causes the wear member to be tightly held to the lip and movement of the wedge in an upward direction enables removal of the wedge and release of the wear member from the lip.
