  • Patent number: 6837132
    Abstract: A paper jam removal tool, for use in clearing jammed paper from a paper shredder, constructed of a single length of wire having a first end and a second end. The first end of the tool leads sequentially into a first laterally extending portion, a first u-bend, a second laterally extending portion, a second u-bend, and a third laterally extending portion. The third laterally extending portion terminates at a central loop portion which wraps around the first and second lateral portions, and finally extends away from the laterally extending portions, perpendicularly thereto, forming a poker portion. The laterally extending portions and their associated u-bends form the handle of the tool. The poker portion of the tool extends perpendicularly from the handle portion and is used to push jammed paper through the blades of the paper shredder, thereby allowing for the continued operation of the paper shredder.
