Abstract A spinning top comprises a casing in which is located a gear including a vertical shaft extending downwardly from the casing, the uppermost portion of the said shaft being a Z-profiled bar, the sidewardly extending arms of which are frictional contact with the ends of oppositely disposed horizontal axles turning in seats provided in the inner wall of the casing. On each of the said horizontal axles a crown wheel is keyed, both crown wheels being in mesh with a pinion, the central axle of which passes through the uppermost part of the spinning top. The said central axle of the pinion is functionally connected with the latter by a ratchet mechanism so that the rotational movement of the pinion is transmitted to the said axle in one direction only. To the outer, free end of the axle is keyed a propeller.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
110 words
A spinning top comprising a hollow body having an inwardly extending bore in which slides a shaft the innermost end of which carries co-directional with the shaft a Z-profiled member, the sidewardly extending portions of the said Z-profiled member being in frictional contact with two oppositely disposed, co-directional axles seated rotationally in the wall of the said hollow body, a crown wheel being fixedly keyed on each of the said axles, both said crown wheels meshing with a pinion, an axle extending from the pinion and being connected therewith for transmission of rotational movement in one direction only, a propeller being fixed to the outer end of the said axle.
Claim 2
Dependent Claim
110 words
A spinning top comprising a hollow body having an inwardly extending bore in which slides a shaft the innermost end of which carries co-directional with the shaft a Z-profiled member, the sidewardly extending portions of the said Z-profiled member being in frictional contact with two oppositely disposed, co-directional axles seated rotationally in the wall of the said hollow body, a crown wheel being fixedly keyed on each of the said axles, both said crown wheels meshing with a pinion, an axle extending from the pinion and being connected therewith for transmission of rotational movement in one direction only, a propeller being fixed to the outer end of the said axle.
Claim 3
Dependent Claim
21 words
The spinning top claimed in claim 1 characterised thereby that the outer end of the said shaft carries an elastic sphere.
Claim 4
Dependent Claim
26 words
The spinning top claimed in claim 1 characterised thereby that the said shaft is surrounded by a spring urging the shaft outwardly of the hollow body.
