Abstract
An anti-jam assembly for incorporation in an article destroying appliance includes a fixed core mount assembly including a first support member spaced apart from a second support member. At least one moveable cutter shaft is disposed between and rotatably mounted to the first and second support members. A third elongate member extends in parallel relationship to the at least one cutter shaft. This third support member is moveable from a first position to at least a second position. The first and the at least second position correspond to a variable width of a feed path directing an article toward the at least one cutter. An arm is affixed to the elongate member and pivotal at a mounting surface when the elongate member moves toward the second position. A sensor activates when it detects movement of the arm. The arm and the sensor are removed from a proximity of the at least one cutter or the feed path.
