Messrs. JULES JUILLERAT-BERTHOUD and ALFRED LEISER, both residing at
Madretsch near Bienne, Canton Berne, Switzerland and both,watch-manufacturers, do
hereby declare the nature of this invention to be as follows:-
A new combined winding, coupling and disengaging gear, consisting of 2 toothed
wheels A & C, the one of which A is fixed at the one extremity of the stem, of
which the winding-knob B forms the other, and the other C fixed in a special and
particular way to the inside part of the watch; this combination of the 2 wheels is
so effected that their immediate grip in each other takes place as soon as the work
is shut (engaging gear) and their immediate putting out of action takes place as
soon as the work is opened (disengaging gear) both engagement and disengage-
ment being effected without any other movement but the shutting or opening of
the work (ie. putting the work in or taking it out of the watch case) so that the
winding up of the watch may at once be effected without the necessity of first
pulling the winding-knob out before shutting the work.

Improvements in Watches.
Messrs. JULES JUILLERAT-BERTHOUD and ALFRED LEISER, hoth residing at
Madretsch near Bienne Canton Berne, Switzerland and both watch-manufacturers, 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:
A watch of the "remontoir system" see drawing left with the provisional specification
i.e. furnished with an outside winding knob B, called system Callote, having but onc
cover, or in case its being manufactured without the same, bearing a dome G on the
dial-side. The whole inside part is fixed to the case by means of a trigger E and
a hinge D. On account of there only being one cover (the other part of the case
being manufactured in one solid piece without soldering) no dust or dirt is able to
enter into the work. On the same account it is necessary, in order to inspect the
work first to open this cover F (or dome G) and then to press the trigger E, so that
the whole of the inside part, turning round the axis of said hinge D is brought outside
the case.
A peculiar toothed wheel (pinion) A is fixed at the one extremity of a
winding stem of which the winding knob B forms the other; every movement of the
latter is therefore communicated to the former. Connected with the springs in the
usual way is another toothed wheel C (corresponding with the first) fixed to the inside
part of the watch in such a special and particular way as to enable it to act
directly on the first wheel A which is fixed to the winding stem. In shutting the
work the teeth of these 2 wheels are brought in firm grip with each other, so that the
movement of each of them (wheels) is communicated to the other.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :
A new combined winding, coupling and disengaging gear consisting of 2 toothed
wheels A and C, the one of which A is fixed at the one extremity of the stem, of
which the winding knob B forms the other, and the other fixed in a special and
particular way to the inside part of the watch; this combination of the 2 wheels is
so effected that their immediate grip in each other takes place as soon as the work is
shut (engaging gear) and their immediate putting out of action takes place as soon as
the work is opened (disengaging gear) both engagement and disengagement being
effected without any other movement but the shutting or opening of the work (ie
putting the work in or taking it out of the watch case) so that the winding up o
the watch may at once be effected without the necessity of first pulling the wind
ing knob out before shutting the work.
