RESERVE
of any kind with Going Barrel.
LOUIS PAUL GUIGNARD watchmaker & merchant, in Fluntern-Sonnenbuhl 4,
Switzerland Zurich do hereby declare the nature of this invention to be as
follows:-
A small mechanism placed at the stopwork of the barrel, or besides the stopwork―
The usual stopwork could be used, but in order to get a steady motion of the indicator
I prefer a modified stopwork-It consists of a pinion, say of 8 teeth (the number has
no importance) fixed upon the barrelarbor, and working with a wheel of 33 or more
or less teeth, one of the teeth being larger for stopping-On this wheel or on the
common starwheel I fix a pinion, working with a wheel pivoting on the barrelarbor-
The size of that wheel & pinion must be made according to the extent of motion
which is wanted for the indicator-The indicator which may be a hand, is fixed on
this last wheel, or if wanted for the symmetry of the dial on any wheel or piece
connected with it-The working of this mechanism is easily understood-By winding
up, admitting the indicator to be at 0 or down, it will by the action of the wheels &
pinions mentioned, make the whole way to, say 32 bours at up till the watch is fully
wound up The watch or clock in going will by the same process bring the indicator
in say 32 hours, to its primitive position, the moving power, being in this latter case,
the turning of the barrel, and the same wheels and pinions, as above, transmitting
the motion.
In this matter, the indicator will always show at a glance, and exactly, whether the
movement is wound up or not, and how many hours it will still run.

of any kind with Going Barrel.
LOUIS PAUL GUIGNARD watchmaker and merchant in Fluntern-Zurich Switzerland
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, accompanied by drawings: Fig. 1. elevation Fig 2 section
Fig. 3. plan
A small mechanism placed at the stopwork of the barrel or beside the stopwork-
The usual stopwork could be used, but in order to get a more steady motion of the
indicator I prefer a modified stopwork-It consists of a pinion c of 4 teeth (the
number has no importance) fixed upon the barrelarbor b, and working with a wheel
of 16 or more or fewer teeth, one the teeth being larger for stopping-On this
wheel, or on the common starwheel is fixed a pinion e working with a wheelf pivoting
on the barrelarbor g. The size of the wheel f, and pinion e, must be made according
to the extent of motion which is wanted for the indicator-The indicator which may
be a hand h, fixed on the wheel for if wanted for the symmetry of the dial,
or not allowed by the disposition of the work, on any wheel or piece connected
with it.
The working of this mechanism is easily understood-By winding up, admitting
the indicator to be at 0 or down, it will by the action of the wheel and pinion
mentioned, make the whole way to say 32 hours at up, till the watch is fully wound
up The watch or clock in going will by the same process bring the indicator in
say 32 hours to its primitive position, the moving power being in this latter case the
turning of the barrel; the same wheel and pinion as above transmitting the motion-
In this manner the indicator will always show at a glance and exactly, whether the
movement is wound up or not and how many hours it will still run.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what inanner the same is to be performed, I declare that what I
claim is :
The employment of a system of wheels and pinions, mounted on the barrel and
barrelarbor of a horological mechanism with going barrel, acting as, or in connection
with, or besides the stopwork, in the way above described, to indicate to what amount
the spring working the same horological mechanism is wound up.
