ABSTRACT:
Apparatus for shearing waste material such as a discarded vehicle tire including parallel first and second rotatable shafts, each having an alternating pattern of driving rings and split sharpenable shear members along the length thereof. The driving rings and the shear members all abut the circumference of the associated shaft. The driving rings are keyed to the shafts and the shearing members are fixed to the driving rings. The shearing members of each shaft are axially aligned with the driving rings of the other shaft and are in meshing relation with the shearing members of the other shaft. The optimal edge-to-edge dimension of the shearing members is maintained after material reduction from the edges by insertion of a shim between the blades that comprise the split shearing members. After each periodic sharpening of the shear members, additional shim are added between the blades or the existing shims are replaced with larger shims.
