Shiftable drive self-propelled toy vehicle
First Claim
1. A motor driven toy wheeled vehicle comprising:
- a body;
a chassis to which the body is attached;
a rear axle and wheel assembly supported for rotation by the chassis;
a front axle and wheel assembly supported for rotation by the chassis;
a motor carried by the chassis;
first transmission means for driving engagement between the motor and one axle and wheel assembly;
second transmission means for driving engagement between the motor and both the rear and front axle and wheel assemblies;
a gear box carried by the chassis for movement relative to the chassis;
the first and second transmission means being supported by the gear box; and
shift means for moving the gear box to selectively engage either the first or second transmission means in its said driving engagement.

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 connection in the neutral position.

18. A motor driven toy wheeled vehicle including:
-
a chassis; front and rear axle and wheel assemblies journaled for rotation in the chassis; a DC electric motor carried by the chassis; a gear box carried by the chassis for movement relative to the chassis; the motor being disposed within the gear box; first gear means for drivingly connecting the motor to one of the axle and wheel assemblies at a first speed; second gear means supported by the gear box for drivingly engaging the motor with both the front and rear axle and wheel assemblies; the second gear means including speed reducing means for driving the front and rear axle and wheel assemblies at a second speed; a DC power source for the motor carried by the vehicle; switch means supported by the gear box for reversing the polarity between the DC power source and the motor to effect reversal of the motor; and a shift lever to control both the reversing switch and the means for selectively engaging either the first or second gear means to drive the vehicle. - View Dependent Claims (19, 20)
