The screw when tightened urges the wear finger toward the cantilever retainer lip. ## Claims ### Claim 1 A gin rib comprising a main rib component having upper and lower ends and an outer support surface adjacent a wear prone area; a sacrificial wear finger having upper and lower ends and being removably mountable on said outer support surface so as to permit removal and replacement of said wear finger when desired, first retaining means engageable with one end of said wear finger for retaining said one end of said wear finger on said outer support surface and a second retainer means engageable with the other end of said wear finger for retaining said other end of said wear finger on said outer support surface and for moving said wear finger longitudinally along said outer support surface toward and into snug contact with said first retaining means on said support surface so as to provide secure retention of said wear finger on said support surface. ### Claim 2 (depends on 1) A gin rib as recited in claim 1, wherein said first retainer means includes a cantilever retainer lip formed in said gin rib and overlying a portion of said one end of said wear finger. ### Claim 3 (depends on 2) A gin rib as recited in claim 2, wherein said second retainer means comprises a threaded member threadably received in said gin rib beneath said wear finger and including an upper downwardly facing wear finger engaging means forcefully engaged with said second end of said wear finger to urge said wear finger longitudinally to force one end of said wear finger into and beneath said cantilever retainer lip. ### Claim 4 (depends on 3) A gin rib as recited in claim 3, wherein said gin rib includes a blind threaded bore having a blind bore axis and said wear finger includes a countersunk bore having a conical countersunk surface having a countersunk axis and said threaded member comprises a machine screw positioned in said blind threaded bore and having a screw axis and a head with a lower conical surface facing and engaging said conical countersunk surface of said wear finger and wherein said blind bore axis is offset relative to said countersunk axis so that axial movement of said machine screw into said blind threaded bore causes said lower conical surface of the machine screw head to engage and react with the countersunk bore of said wear finger to urge the wear finger longitudinally toward said cantilever retainer lip. ### Claim 5 (depends on 2) A gin rib as recited in claim 2, wherein said cantilever retainer lip means has an outer end termination of V-shaped configuration and said one end of said wear finger includes a V-shaped surface which is of the same configuration as the outer end termination of said cantilever retainer lip means and which is matingly received in said outer end termination of said cantilever retainer lip means. ### Claim 6 (depends on 5) A gin rib as recited in claim 5, wherein said second retainer means comprises a threaded member threadably received in said gin rib beneath said wear finger and including an upper downwardly facing wear finger engaging means forcefully engaged with said second end of said wear finger to urge said wear finger longitudinally to force said one end of said wear finger into and beneath said cantilever retainer lip. ### Claim 7 (depends on 6) A gin rib as recited in claim 6, wherein said gin rib includes a blind threaded bore having a blind bore axis and said wear finger includes a countersunk bore having a conical countersunk surface having a countersunk axis and said threaded member comprises a machine screw positioned in said blind threaded bore and having a screw axis and a head with a lower conical surface facing and engaging said conical countersunk surface of said wear finger and wherein said blind bore axis is offset relative to said countersunk axis so that axial movement of said machine screw into said blind threaded bore causes said lower conical surface of the machine screw head to engage and react with the countersunk bore of said wear finger to urge the wear finger longitudinally toward cantilever retainer lip. ### Claim 8 (depends on 2) A gin rib as recited in claim 2, wherein said wear finger portion includes a lower lock lip extending beneath said cantilever retainer lip of said gin rib and having a V-shaped outer end surface matingly received in a V-shaped surface of the same configuration provided in said gin rib. ### Claim 9 (depends on 8) A gin rib as recited in claim 8, wherein said cantilever retainer lip has an outer end termination of V-shaped configuration and said one end of said wear finger includes a V-shaped surface which is of the same configuration as the V-shaped outer end surface of said cantilever retainer lip and is matingly received in said V-shaped outer end surface of said cantilever lip retainer. ### Claim 10 (depends on 9) A gin rib as recited in claim 9, wherein said second retainer means comprises a threaded member threadably received in said gin rib beneath said wear finger and including an upper downwardly facing finger engaging means forcefully engaged with said second end of said wear finger to urge said wear finger longitudinally to push said one end of said wear finger into the cantilever retainer lip. ### Claim 11 (depends on 10) A gin rib as recited in claim 10, wherein said gin rib includes a blind threaded bore having a blind bore axis and said wear finger includes a countersunk bore having a conical countersunk surface having a countersunk axis and said threaded member comprises a machine screw threadably received in said blind threaded bore having a screw axis and a head with a lower surface facing and engaging said conical countersunk surface of said wear finger and wherein said blind bore axis is offset relative to said countersunk axis so that axial movement of said machine screw into said blind threaded bore causes said lower surface of the machine screw head to engage and react with the countersunk bore of said wear finger to urge the wear finger longitudinally toward said overlying portion of said cantilever retainer lip. ### Claim 12 (depends on 1) A gin rib as recited in claim 1, wherein said one end of said wear finger is said lower end of said wear finger.
