PROVISIONAL SPECIFICATION.
A. Spinning Top for Exhibiting Automatic Variations in Pattern
or Colour.
JOHN COLLINS, 172, Maple Road, Penge, London, S.E., Cycle Fitter, do hereby
declare the nature of this invention to be as follows:-
A disc of metal or other suitable material which I call the power disc A
with a stem B in the centre thereof. A spindle C passing through the stem B
having at its lower end a boss or foot 1) which I prefer to cover with rubber
so that when the top is spun the spindle does not move. A disc preferably of
light material which I call the pattern disc E, which may have sections cut
out, moving at a speed differing from that of the power disc or across its
plane of rotation. Suitable mechanism to produce the said movements one
device, among others being as follows. A pinion F fixed to the spindle C
actuating a train carried round by the disc A the last wheel of the train carry-
ing an excentric pin G which passing through a hole or slot in the disc E
varies its position relatively to the disc A.
I may make the pattern disc as E or E" or of any desirable pattern or colour
and I may also have various patterns or colours on the disc A. In E" the
spindle C passes through the slot and the pin & through the hole but the
reverse in E'.
In the drawing the train wheels are indicated by their pitch circles and the
plan is drawn with disc E removed.
A Spinning Top for Exhibiting Automatic Variations in Pattern
or Colour.
JOHN COLLINS, 172, Maple Road, Penge, London, S.E., Cycle Fitter, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
-
The object of this invention is to construct a spinning top which shall auto-
matically vary in colour or pattern.
In the drawings left with the Provisional Specification, the disc A, which I
prefer to make of metal, is shown with a winding stem B fixed to it. Through
the centre of stem B and disc A passes the spindle or axle C having at its
lower end a boss or foot D of india rubber or the like to prevent the spindle C
revolving when the top is spun. On the axle or spindle C is fixed a pinion F

page_text: gearing with a train of wheels carried round it by the dise A on which they
are pivoted the last wheel of the train carrying an excentric pin G.
The disc E is made of thin sheet metal or stiff cardboard or the like and
has on its surface variously coloured circles struck from two centres, the dis-
tance apart of these centres being equal to the throw of the excentric pin G.
The disc E has a slot and a small hole, the axle C passing through the slot
and the pin G through the hole; then when a string is wound round the
stem B and the top is spun in the ordinary manner the pin G will be carried
round the axle C and will also have a secondary motion round the axis of the
gear wheel to which it is attached, and the disc E" moving with it will appa-
rently vary in colour or pattern as the centres of its circles alternately coincide
with the centre of the disc A.
In another form of the same invention the surface of the disc A is divided
into sections by lines radiating from its centre, and the disc E¹ divided in a
similar manner has alternate sections cut out the remaining ones being
coloured. Alternate sections on the disc A are coloured to match the disc E¹
and the remainder in a different manner. In this form of disc E the axle C is
passed through the small hole and the pin G through the slot, than when the
top is spun as before described the disc E¹ rotates round the axle C and by the
movement of the pin G has a vibratory movement also; thus different sections
of disc A are alternately covered and exposed and the colours on the surface
appear to change.
It is clear that instead of toothed wheels I may employ friction gearing or
other suitable device and instead of a rubber foot I may have a stand or holder
also that the discs E and E may be interchangeable on the disc A and may
be of many designs beside those shown in E¹ and E.
If so desired a handle may be placed on the upper end of the axle C but it
should be removable so that the discs E and E and the like may be easily
changed.
In the drawings left with the Provisional Specification, to which the fore-
going description applies, the gear wheels are indicated by their pitch circles
and the plan is drawn with disc E removed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
(1) A spinning top in which the spindle or axle is prevented from turning
for the purpose of driving gearing.carried round it for the purposes specified
and the like.
(2) A spinning top in which two or more discs rotating round a spindle or
axle are by means of gearing caused to travel at different speeds or in different
directions for the purposes specified and the like.
(3) A spinning top with a disc A, a winding stem B, a spindle C with a foot
or boss D, a disc E or E" and suitable gearing to produce the movements
described, substantially as shown in the drawings left with the Provisional
Specification.
