PROVISIONAL SPECIFICATION.
Improved Watch Mechanism adapted to Go for Long Periods Without
Re-winding.
A communication from abroad by WILHELM KÖHLER, of No. 61, Königstrasse,
Fürth, in Bavaria, in the German Empire, Watchmaker.
I, JOHN CORRY FELL, of the Firm of Fell and James, of 1, Queen Victoria Street,
in the City of London, Chartered Patent Agent, do hereby declare the nature of
this invention to be as follows:-.
This invention relates to the application of a divided mechanism for watches
combination with transmitting wheels and corresponding spring casing so that
the mechanism can be kept going for about one year by winding it once.
In order that this invention may be the better understood, I now proceed to
describe the same reference being had to the accompanying drawings and to the
letters and figures marked thereon.
Figures 1-5 show various views of such a yearly watch.
The plates A and B, of which the lower plate A is solid, and the plate B has a
circular part removed to admit the spring casing (Figures 1, 2 and 4) are connected
by pillars 1, 2, 3, 4, and carry the pivot bearings for the two transmission
wheels G and F. The plate A carries further the lower pivot bearings for the
driving arbor and the spring casing arbor h.
a₁
The upper pivot of the spring casing arbor h rests in the crescent plate D,
Figure 2, situated also on the pillars 1, 2, 3. The bearing for the upper pivot of
the driving arbor a is in the block E screwed on to the plate B.
The spring casing H and the transmitting wheels Ġ and F, and the driving
arbor a, engage by gearing contact.
The large first motion wheel b of a watch is fixed to the driving arbor a, but
so that the wheel b is situated above the plate B, Figures 1, 2 and 4. The other
mechanism and escapement of a watch is screwed beside this wheel b to the plate B,
by means of scewe r r, so that the wheel b engages with the second motion small
wheel.
In this manner it is possible to construct the small wheels on the half plate C
delicate so as to require little force, the spring casing with the transmission wheels
and the attachments thereof being constructed stronger so as to offer greater dura-
bility. In consequence the mechanism can be kept going for a long period without
consuming much force.
In Figures 1 and 2 the half plate C is shown screwed on with the escapement;
in Figure 1, without the spring casing, and in Fig. 2 with the spring casing and
the upper cover plate D.
Figure 3 shows the side of the plate A towards the dial and the arrangement
of the hand mechanism.

Improved Watch Mechanism adapted to Go for Long Periods Without
Re-winding.
A communication from abroad by WILHELM KÖHLER, of No. 61, Königstrasse,
Fürth, in Bavaria, in the German Empire, Watchmaker.
I, JOHN CORRY FELL, of the Firm of Fell and James, of 1, Queen Victoria Street,
in the City of London, Chartered Patent Agent, 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 the application of a divided mechanism for watches
in combination with transmitting wheels and corresponding spring casing so that
the mechanism can be kept going for about one year by winding at once.
In order that this invention may be the better understood I now proceed to
describe the same reference being had to the drawings accompanying the
Provisional Specification and to the letters and figures marked thereon.
Figures 15 show various views of such a yearly watch.
The plates A and B of which the lower plate A is solid and the plate B has a
circular part removed to admit the spring casing (Figures 1, 2 and 4), are connected
by pillars 1, 2, 3, 4 and carry the pivot bearings for the two transmission
wheels G and F. The plate A carries further the lower pivot bearings for the
driving arbor a and the spring casing arbor h.
The upper pivot of the spring casing arbor h rests in the crescent plate D,
Figure 2, situated also on the pillars, 1, 2, 3. The bearing for the upper pivot of
the driving arbor a is in the block E screwed on to the plate B.
The spring casing H and the transmitting wheels G and F, and the driving
arbor a engage by gearing contact.
The large first motion wheel b of a watch is fixed to the driving arbor a, but
so that the wheel b is situated above the plate B, Figures 1, 2, and 4. The other
mechanism and escapement of a watch is screwed beside this wheel b to the plate B,
by means of screws rr so that the wheel b engages with the second motion small
wheel.
In this manner it is possible to construct the small wheels on the half plate C
delicate so as to require little force, the spring casing with the transmission wheels
and the attachments thereof being constructed stronger so as to offer greater dura-
bility. In consequence the mechanism can be kept going for a long period without
consuming much force.
In Figures 1 and 2 the half plate C is shown screwed on with the escapement;
in Figure 1 without the spring casing, and in Figure 2 with the spring casing and
the upper cover plate D.
Figure 3 shows the side of the plate A towards the dial and the arrangement
of the hand mechanism.
Figure 5 shows the half plate C with the small wheel mechanism and the
escapement.

page_text: Having now particularly described and ascertained the nature of this said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
In combination in a watch, double superposed main plates, a main spring trans-
mission mechanism of exceptional strength and the usual delicate watch wheel and
escapement mechanism divided by the said plates into separate planes, to form a
watch adapted to go for a long period without re-winding substantially as described.
