Improvements in Watches.
I, AMÉDÉE DOUARD PERE of 32 Rue Flora, Bienne, in the Republic of
Switzerland, Watch Maker, do hereby declare the nature of this invention to be as
follows:-
The invention consists in a new combination and arrangement of the train of a
watch adapted for going during a period of eight consecutive days without being
wound up.
On the main plate on which the works are fixed and at a suitable distance there-
from, is secured by means of suitable pins and screws a smaller plate. The main
plate moreover carries an escapement bridge, an anchor bridge and a bracket.
Between the main plate and the small plate the following parts are located: a
spring-barrel of large diameter having 140 teeth and gearing with a pinion having
10 teeth of a first wheel which has 120 teeth. The said first wheel gears with a
pinion having 10 teeth of a second wheel provided with 100 teeth, which gears in a
ten-toothed pinion of a third wheel which has 70 teeth. The escapement bridge
carries an escapement-wheel the pinion of which has seven teeth and is acted upon
by the above-mentioned third wheel.
The anchor escapement may be of any suitable construction.
The end of the arbor of the first wheel projecting through the main plate, carries,
in a suitable recess provided under the dial, a small wheel upon which is fixed a
second small wheel having 24 teeth. The first small wheel being only intended to
be acted upon by the handsetting mechanism to transmit to the second small wheel
the rotation of the crown-pinion for setting the hands, the number of its teeth is of
no importance. The second small wheel gears with a first minute wheel which is
provided with 48 teeth and gears with the first minute pinion having 12 teeth which
bear the minute-hand and the pivot of which is screwed to the main plate. The
pinion with 16 teeth of the first minute wheel gears with the hour-wheel which has
48 teeth and bears the hour-hand.
The spring-barrel-ratchet-wheel is lodged in a recess of the main plate and may
be approached by means of suitable recesses provided under the dial, on one hand
by the click acted upon by means of a spring and on the other hand by the
regulating-wheel pivoted to a lever. The latter oscillates upon a disc fixed to the
plate and acting at the same time as a pivot of a crown-wheel which gears together
the regulating wheel and the hand setting-wheel. A spring normally keeps the
regulating wheel in gear with the ratchet wheel of the spring barrel; but the lever
may be oscillated by means of a push-piece so as to disengage the regulating wheel
from the ratchet-wheel and to put the hand-setting wheel into gear with the above-
mentioned small wheel.

I, AMÉDÉE DOUARD PERE of 32 Rue Flora, Bienne, in the Republic of
Switzerland, Watch Maker, 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 :-
This invention relates to watches and consists in a new combination and arrange-
ment of the train of wheels of a watch adapted for going during a period of eight
consecutive days without being wound up.
In the accompanying drawing
Figure 1 is a face view of the back plate of the watch.
Figure 2 is a face view of the main plate of the watch, that is to say of the parts
located under the dial.
Figure 3 is a diagrammatical view of the wheels and
Figure 4 is an horizontal section of the watch drawn to an enlarged scale.
Similar letters of reference indicate corresponding parts in all the figures of the
drawing.
On the main plate A. on which the works are fixed and at the desired distance
therefrom is secured by means of suitable pins and screws a a smaller plate B.
The said main plate A also carries an escapement bridge C, a bridge D and a
bracket E.
Between the main plate A and the back plate B the following parts are located
as indicated in Figure 3: a spring-barrel F of large diameter having 140 teeth and
gearing with a pinion g having 10 teeth attached to the first wheel G which has
120 teeth. The latter gears with a pinion having 10 teeth attached to a second
wheel H provided with 100 teeth, which gears with a seven-toothed pinion i attached
to a third wheel I which has 70 teeth. The escapement bridge C supports an
escapement-wheel J, the pinion j of which has seven teeth and is acted upon by
the above-mentioned third wheel I. The escapement may be of any suitable
construction.
The end of the arbor of the first wheel G projects through the main plate A and
carries in a suitable recess provided under the dial, a small wheel K (see Figures 2
and 4) upon which is fixed a second small wheel & having 24 teeth. The wheel K
being only intended to be acted upon by the handsetting mechanism to transmit to
the wheel k the rotation of the crown-pinion for setting the hands, the number of
its teeth is of no importance. The wheel k gears with a minute wheel L which is
provided with 48 teeth and gears with the minute-pinion M having 12 teeth which
bears the minute-hand and the pivot m of which is screwed to the plate A
(Figure 4). The pinion with 16 teeth of the minute-wheel L gears with the
hour-wheel N which has 48 teeth and bears the hour-hand.
The spring-barrel-ratchet-wheel O is located in a recess of the main plate A and
is rendered accessible by means of suitable recesses provided under the dial, on one
hand by the click P acted upon by means of a spring p and on the other hand by
the regulating-wheel Q pivoted to a lever R. The latter oscillates upon a discr
fixed to the plate and acting at the same time as a pivot of a crown-wheel S which
gears together the regulating wheel Q and the hand-setting-wheel T. A spring l
normally keeps the regulating wheel Q in gear with the ratchet wheel O of the
spring barrel; but the lever may be oscillated by means of a push-piece acting in
the direction of the arrow r so as to disengage the regulating wheel Q from the
ratchet-wheel and to put the hand-setting wheel T into gear with the above-
mentioned small wheel K.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An improved watch adapted to operate during a period of eight consecutive
days constructed and operating substantially as hereinbefore described and shown
in the drawing.
