ABSTRACT:
A toy vehicle propelled by a bi-directional, miniature d-c motor, coupled by a clutch through a gear train to a wheel axle. A manually-operated shift stick mechanism is operatively linked both to the clutch and to a polarity-reversing switch interposed between the motor and a battery. The arrangement is such that when the stick is in neutral, the battery is disconnected and the clutch is disengaged, whereby the vehicle is then free rolling. When the stick is put in its forward position, the clutch is engaged to couple the motor to the gear train and the switch is operated to apply voltage to the motor in a polarity causing the vehicle to travel in the forward direction. When the stick is put in its reverse position, the clutch is again engaged and the switch is operated to apply voltage to the motor in the reverse polarity, causing the vehicle to travel in the opposite direction.
