More Information
Summary:A motorized cart for the transportation of at least one mail bag includes a box-like frame having a plurality of hooks spaced along its top surface to which may be attached one or more mail bags. A pair of wheels are fixedly mounted to an axle disposed along the bottom surface of the frame. A third wheel is attached to the bottom surface of the frame to provide additional locomotive stability. To obviate manual transportation of the cart, the frame houses a motor which drives the rotation of the pair of wheels, a battery which supplies an initial electrical current to the motor, and a starter/generator which re-circulates electrical current to the motor. The revolution speed of the motor is controlled with a throttle actuated by twisting the handle mounted to the frame. A centrifugal clutch engages the motor and the axle once the motor attains a certain threshold revolution speed. A hand brake lever, disposed just below the handle and actuated by squeezing the hand brake lever towards the handle, is interconnected to a frictional assembly on the third wheel for the purpose of decreasing the vehicle's translocational velocity.
