  • Patent number: 8783308
    Abstract: The present disclosure provides a device and method that enable the efficient reduction of stumps. In one embodiment the stump removal methods and devices according to the present disclosure allow the operator to have a clear view of the work area during operation, and the ability to move the reduction device through a wide range of motion during operation. In one embodiment, the material reduction tool pivots relative to the chassis in the vertical plane about multiple pivot points. In some embodiments the device includes a retractable auxiliary control panel located at the end of the device opposite the material reduction tool. The control panel enables the operator to direct the movement of the device from the end of the device and thereby enable the device to maneuver through narrow spaces.

  • Patent number: 8777138
    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.
