REPLACEABLE PROTECTIVE MEANS FOR SHREDDER COMPONENTS Abstract of the Disclosure Replaceable protective means for protecting a component of a shredder from excessive wear includes a protective cap of hardened, wear resistant metal, and at least two pins and washers of readily weldable metal. The protective cap has a U-shaped channel for receiving a por- tion of the periphery of the component. The opposed walls of the U-shaped channel each have at least one pair of pin-receiving openings and the openings in each wall are aligned with those in the opposed wall. When the cap is positioned in place on the component with the pin receiving openings in the opposed walls of the cap aligned with open- ings which extend through the end disc, the pins which have enlarged heads at one end which are larger than the openings in the disc can be inserted into the aligned openings and secured in place by welding a washer which also is larger in diameter than the openings in the disc to the other end of each of the pins. The protective cap is thus retained in place on the component by the welded pin and washer combina- tions which are not directly attached to either the cap or the component.
