Abstract
A toy work vehicle propelled by a bi-directional d-c motor in a forward or reverse direction depending on the polarity of battery voltage applied thereto, the vehicle including a power take-off device driven by the same motor to raise or lower a load. A gear shift mechanism operatively coupled either to the wheel axles or to the power take-off device, is controlled by a shift stick which in neutral operatively couples the motor only to the power take-off device. The shift stick is movable to a lateral position having a forward and a reverse mode in which the motor is operatively coupled to the wheel axles. The shift stick also cooperates with a slide carrying the movable contacts of a polarity-reversing switch connecting the battery to the motor such that when the stick is in neutral the motor is disconnected; when the stick is in the forward mode, the battery voltage is applied in a polarity causing forward motion of the wheels; and when the stick is in the reverse mode, the polarity is reversed to cause reverse wheel motion. Coacting with the switch slide is a power take-off lever having a forward and back position such that when the shift stick is in neutral and the lever is in its forward mode, this causes the motor to drive the power take-off device to raise the load, and when the shift stick is in neutral and the lever is in its back mode, this causes the device to lower the load.
