Pullback motor
text:
A pullback motor is a simple clockwork motor used in toy cars. A patent for them was granted to Bertrand 'Fred' Francis in 1952 as a keyless clockwork motor. Pulling the car backward winds up an internal spiral spring; a flat spiral rather than a helical coil spring. When released, the car is propelled forward by the spring. When the spring has unwound and the car is moving, the motor is disengaged by a clutch or ratchet and the car then rolls freely onward. Often the clutch mechanism is geared
