Patent ID: 8091915

Claim:
An animated novelty device for mounting on a ball of a trailer hitch on a vehicle, the device comprising an electric motor for imparting motion to selected elements of the device, the motor being electrically connected to a brake light energizing line of the vehicle, whereby the selected elements of the device are set in motion by energizing the brake light energizing line, and a gear box attached to the electric motor, the gear box comprising a plurality of gears that provide movement to an output shaft, whereby the plurality of gears convert a rotation of a rotor of the electric motor to an appropriate speed and torque at the output shaft of the gear box to cause rotation of a drive wheel that has at least connection attached to the output shaft of the gear box, and whereby the drive wheel comprises an offset point through which a distal end of a lever arm is attached to the drive wheel and wherein a proximal end of the lever arm is connected to an offset point on a push and pull wheel, so as to create an oscillating motion of the push and pull wheel about a center point of the push and pull wheel.
