Abstract
A gyroscopic toy is provided having a shaft to which is coupled a flywheel. A drive gear is used to spin the shaft and flywheel for spinning the toy. A pinion gear is rotated to impart spin energy to the shaft and flywheel and thus to the toy. A gearing mechanism couples the drive gear to the pinion gear when the pinion gear is rotated in a first direction and decouples from the drive gear when the pinion gear is rotated in a second opposite direction. A transmission may be provided allowing for at least two different gearing sets to be selectively coupled to the drive gear when the pinion gear is rotated in the first direction.
