Shredder Head Having Motor Driven Shredder Blades and an Associated Safety Feature and/or a Method of Shredding Material
First Claim
Patent Images
1. A shredder having motor driven shredder blades and an associated safety feature, comprising:
- a shredder head housing defining a slot adapted to receive material to be shredded;
a plurality of shredder blades disposed within the shredder head housing and adapted to shred the material inserted into the slot;
a motor disposed within the shredder head housing and configured to drive the plurality of shredder blades;
a controller disposed at least partially within the shredder head housing and adapted to monitor a temperature of the motor;
a light indicator mechanism located on the shredder and being under operative control of the controller, wherein the controller causes the light indicator mechanism to generate a first light condition when the motor is operating within normal temperature parameters, the controller causes the light indicator mechanism to generate a second light condition when the motor temperature exceeds normal temperature parameters but is less than a predetermined overheat temperature, the controller causes the light indicator mechanism to generate a third light condition when the motor temperature is equal to or greater than the predetermined overheat condition.
