Abstract
An electric motor driven toy wheeled vehicle is provided with a projecting shift lever movable through an "H" pattern for selectively shifting the vehicle into any one of neutral, two-wheel high speed forward drive, two-wheel high speed reverse drive, four-wheel low speed forward drive, or four-wheel low speed reverse drive. The front and rear axles with their respective wheels and drive gears are journaled for rotation in a chassis which also carries a gear box for lateral axial movement. A mount for the shift lever and motor is supported by the gear box for movement in the longitudinal direction of the chassis transverse to the axial direction. The gear box also carries a high speed two-wheel drive gear train continuously connected to the motor and which can be engaged by movement to one side to drive the rear wheels and a second low speed four-wheel drive gear train also continuously connected to the motor that can be engaged by movement to the other side to drive both the front and rear wheels. A switch with its movable element carried by the mount changes the polarity of the voltage from a DC power source to effect reversal of the motor as well as breaking the electrical conne…
