PROVISIONAL SPECIFICATION.
Improvements in Tourbillon Watches.
ANDREW TAYLOR 62 Enmore Road, South Norwood London Watchmaker do
hereby declare the nature of this invention to be as follows:-
:-
My improvements consist of a carriage carrying the third and fourth wheels and
the escapement the carriage being driven by centre wheel or supplementary wheel
and power transmitted to third wheel by a toothed gearing or internal wheel
secured to plate connection being made between the internal toothed gearing and
third pinion by an idle wheel pivoted in the carriage. The centre wheel may be
driven in either direction and may also be out of the centre of the watch thus
giving greater space for the barrel and carriage.

ANDREW TAYLOR 62, Eumore Road, South Norwood, London, S.E.
Watchmaker, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The drawing accompanying this following description is an illustration of what
I have named an annular tourbillon; its purpose is to make the balance of a
watch, a chronometer, a carriage clock or any other portable time-keeper turu
round itself in any given time (the drawing is adapted for a cycle of one hour).
The object in view is to make a watch or other portable time-keeper measure
time to the same precision in whatever side position it may be placed.
To obtain this object I use a carriage carrying the third & fourth wheels and the
escapement, the carriage being driven by the centre wheel or a supplementary
wheel, and power transmitted to the third wheel by an annular wheel secured to
the pillar plate, connexion being made between the annular wheel and the third
pinion by an idle wheel pivoted in the carriage. If a slower rate of speed is
required, the supplementary wheel may be dispensed with and an additional wheel
introduced into the carriage. The centre wheel may be driven in either direction,
and may also be out of the centre of the watch, thus giving greater space for the
barrel & carriage.

B is the pillars of the carriage.
C is the fourth wheel pivoted in carriage.
D is the third wheel pivoted in carriage.
E is the idle wheel pivoted in carriage.
F is the annular wheel secured to pillar plate.
G is the supplementary centre wheel pivoted in frames.

K is the cock carrying upper pivot of carriage.
Lis the upper pivot of carriage.
M is the lower pivot of carriage.
N is the lower pivot of fourth wheel passing thro' lower pivot of carriage.
O is the pillar plate.
P is the wheel secured to carriage and driven by supplementary centre wheel.
What I desire protection upon is the annular wheel F.
Having now particularly described and ascertained the nature of my inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :
Having invented a means of making a watch, chronometer, or clock keep the
same time in whatever side position it may be placed by employing an annular
wheel secured to the plate to transmit the power to the third wheel, connexion
being made between the annular wheel & the third pinion by an idle wheel
pivoted in the carriage.
