Shredder jam clear apparatus
First Claim
1. A paper shredder having an electric motor coupled to shredder blades, comprising:
- a shredder throat having a fixed throat blade and a moveable throat blade disposed opposite the fixed throat blade, wherein the moveable throat blade provides a wide gap shredder throat and a normal gap shredder throat with respect to the fixed throat blade;
a cam coupled to the moveable throat blade; and
a power control switch engageable with the cam and having an engaged mode and a disengaged mode, wherein the engaged mode corresponds to a normal gap shredder throat, wherein the disengaged mode corresponds to a wide gap shredder throat, wherein in the engaged mode the cam positions the power control switch to provide electrical power to the electric motor, and wherein in the disengaged mode the cam positions the power control switch to block electrical power to the electric motor.

Abstract
A paper shredder having shredder cover and a motor coupled to shredder blades includes a shredder throat in proximity to shredder blades. The shredder throat has a moveable blade, and a fixed blade. A cam coupled to the moveable blade is in communication with a power switch plunger. When the shredder is in the NORMAL/ON position, a throat gap is in its normal position and the cam positions the plunger to power to the motor. When the shredder is in the JAM CLEAR/OFF position, the throat gap is in its wide position and the cam positions the plunger to remove power to the motor. A method is provided, including providing a moveable blade; sensing a throat jammed condition; releasing the moveable blade; moving the moveable blade to a wide gap position; sensing the moveable blade in the wide gap position; turning off the motor in response to the sensing.
