Abstract
A rotating claw drum for shredding discarded material (such as used carpet) is created from flat circular plates that are stacked tightly together on a driveshaft or drum, to create an impermeable drum face that prevents particulates from entering and fouling the internal mechanisms. Each flat plate is provided with at least one claw-holding slot in its outer rim; 6 to 12 slots preferably should be provided in each plate. Locking means (such as a locking bar that will pass through aligned locking notches in the slots and claws) will lock the claws in place while the drum is in use. After the drum has been stopped, a locking bar can be removed, to release a damaged claw from its slot so it can be replaced, without having to disturb any other claws. Each claw-holding slot can also provide a remover notch, which will allow a remover bar with a wedged end to be hammered through a set of aligned remover notches, to dislodge the claws in a row, enabling removal of a damaged claw even if the claw is firmly stuck in its slot. This claw drum can be used in a three-cylinder shredding device that provides good results when used to shred discarded carpet.
