ABSTRACT:
A shredder for cutting carbon paper of the type used for credit purchases into indescernible pieces by a high speed cutting blade safely located within an enclosed housing having a lower collection receptacle. A pair of feed rolls moves the carbon paper at a controlled rate through a chute generally perpendicularly into the horizontal cutting path of the blade. One of the feed rolls is power driven by an electric motor. A single push button having a pair of indicating lights controls the drive motors for the blade and for the feed rolls. Depressing of the button while the blade is rotating reverses the blade and feed roll rotation to prevent jamming. Once actuated a timing circuit maintains the blade rotating for generally 10 seconds. A magnet is mounted on the collection receptacle closely adjacent a magnetic switch to provide a safety interlock to prevent the blade motor from being energized when the cover is removed from the collection receptacle. The invention also encompasses a method for shredding carbon paper.
