- 15 - "BARN SCRAPER DRIVE ASSEMBLY" ABSTRACT The drive motor is pivotally supported axially with- in the frame so that it rotates slightly if the torque of the motor increases due to the scraper assembly being impeded by animals, equipment, broken slats or the like. This actuates a reversing switch thus reversing the movement of the scraper assembly. If desired, an electric shock circuit can be in- cluded which is actuated first, in case the obstruction is an animal. If the animal moves away from the scraper then the scraper proceeds as the reversing switch has not been actuated at this time.
