  • Patent number: 10005084
    Abstract: An article destruction device includes an electric motor driving at least one moving component. An indication panel includes at least three visual indicators situated in sequence. Each visual indicator is associated with a stage of an approaching overload (motor cool down) condition. A first visual indicator lights when the motor or corresponding sensor temperature is below a first threshold, i.e., when the device is first powered on. A second indicator lights when the temperature exceeds the first threshold and is below at least a second threshold, i.e., the temperature is approaching a fault condition. A last visual indicator lights when the temperature exceeds the first and the at least second thresholds, i.e., the fault condition is met. A thermistor on the motor energizes (self-heats) with the motor. A thermostatic switch controls current flow through windings of the motor depending on measured temperatures meeting operating and equilibrium temperature thresholds.

  • Patent number: 8317118
    Abstract: A chad containment bin includes a chad containment space formed by a pair of opposing longitudinally extending sidewalls connected by a pair of opposing, laterally extending sidewalls. A shredder head assembly is situated above the chad containment bin. A cabinet body supports the shredder head assembly while removeably housing the chad containment bin. A generally vertically oriented support member extends upwardly from a first of the longitudinally extending sidewalls. The support member includes a handle on an outer face for carrying the chad containment bin. A panel is pivotally connected to the chad containment bin for providing access to the chad containment space when the chad containment bin is suspended by the handle over a waste receptacle.
