摘要：A spinning top comprises a casing in which is located a gear including a verticalshaft extending downwardly from the casing, the uppermost portion of the said shaftbeing a Z-profiled bar, the sidewardly extending arms of which are frictional contact withthe ends of oppositely disposed horizontal axles turning in seats provided in the innerwall of the casing. On each of the said horizontal axles a crown wheel is keyed, bothcrown wheels being in mesh with a pinion, the central axle of which passes through theuppermost part of the spinning top. The said central axle of the pinion is functionallyconnected with the latter by a ratchet mechanism so that the rotational movement of thepinion is transmitted to the said axle in one direction only. To the outer, free end of theaxle is keyed a propeller.
