Patent number: 9242247Abstract: A wear assembly for use on a driven roll for earth-working machines and the like operations that eases replacement of the wear parts, lengthens the life of the bases, reduces the amount of throw-away material to be discarded, and has a lower manufacturing cost. The wear part overlies and protects the base to prolong the useable life of the base, lessen machine downtime, and reduce throw-away material. The use of an overlying adapter eases and speeds replacement of the wear parts to further limit downtime of the machine. The wear part is preferably a two-piece component with no machined parts for a lower manufacturing cost and easy replacement.Type: GrantFiled: October 9, 2013Date of Patent: January 26, 2016Assignee: ESCO CorporationInventors: Stephen M. Lafond, Cameron R. Leedham, Christopher M. Carpenter, Dallas Chapple
