Abstract
A hand-held device for shredding paper comprising a pair of rotary cutting wheels disposed within a housing between an inlet slot and an outlet slot. A motor is positioned in the handle to drive the cutting wheels through a gear assembly. One wheel serves as a drive wheel, which is coupled directly to the gear assembly, and the other wheel serves as an idler, driven from a spur gear attached to the drive wheel at the end opposite a gear case. Paper sheets are fed into the inlet slot and pulled between the wheels. Wheels are comprised of a stack of alternating discs of a large and small radius, and staggered so as to allow the two wheels to be interleaved while rotating in opposite (clockwise and counterclockwise) directions and maintain clearance. Large discs have a frictional edge to grab and feed the paper into the intersection of the wheels, tearing the paper into strips and forcing the strips into the outlet slot. A battery compartment in the handle contains the batteries for energizing the motor.
