page_text: I, IRENÉE AUBRY, of Saignelégier, in Switzerland, Watch Manufacturer, do
hereby declare the nature of this invention to be as follows:―
My Invention consists of a special arrangement of a watch-mechanism intended
to work 40 days or more consecutively, without being wound up again.
In the accompanying drawings, Fig. 1 is a front view of the watch mechanism,
as the same presents itself when the watch case has been opened.
Fig. 2 is a view of the ring J. Fig. 3 is a top view of the plate Q, with the
wheels and bridges fixed thereon. Fig. 4 is a back view of the same. Fig. 5,
shews the top. of plate A, when plate has been removed. Fig. 6 is a back view
of the plate A, as the same presents itself when the hands and the dial have been
taken off. Fig. 7 is a vertical section, through the line X, Y, Z of fig. 1, on an
enlarged scale, and Fig. 8 shews the dial of the watch.
For all the figures similar letters refer to similar pieces or parts.
According to my Invention, the motive power is composed of a long main-
spring R (fig. 6) placed in a hollow plate A. One end of the spring is affixed to
the inner edge of plate A, and the other is screwed to the hub B¹, of wheel B,
which is placed in a sinking of plate A...
The wheel B drives a wheel C, which is affixed to the axis of the first wheel D
of the works. The wheel D drives a wheel E, which makes one revolution in the
hour and which drives a wheel F, gearing into the pinion of the center-wheel G
which makes one revolution every minute. The axis of G traverses the whole of
the works and carries a second-hand S.
The wheel G drives an escapement, of any system, provided with a balance-
wheel I.
The wheel B revolves around a cannon A¹, forming part of the plate A.
With a view to diminish the friction of the spring R, upon the bottom of plate A,
the latter is provided with fillets a, placed radially.
A pinion M, with square pin L, is intended to wind up the spring. It may gear
directly into the wheel B, or into an intermediate wheel N driving the wheel B.
According to the arrangement of the watch, the pinion M, may be located at any
place whatever in the circumference of the watch. In some cases it may be so
placed as to be acted upon by a stem located in the pendant.

page_text: During the winding up of the spring, the wheel C, must be able to turn back-
wards without removing the wheel D. Therefore wheel C is affixed to the axis
of D whilst this latter is placed loosely thereon.
A click-wheel d, with click e and spring † transmits the forward motion of
wheel C to wheel D (see fig. 3).
The lower end of the axis of D is supported by the plate A, whilst its upper end
is supported by a projection J' of the ring J.
The other movers of the watch are supported by the plate Q and the bridges E,
F¹, G¹, H¹, and F. The axis of the wheel E, traverses the plate Q and bears a
wheel m, placed in a recess between Q and A.
The wheel m drives, by means of a transmitting wheel n, the cannon-wheel o
bearing the minute-hand W.
The cannon-wheel O (with 72 teeth) which carries the hour-hand V,
the pinion of wheel n, provided with 6 teeth.
gears into
As wheel B has 40 teeth and C 10, each revolution of B produces 4 revolutions
of C, that is to say, of wheel D. This latter being provided with 120 teeth and
the pinion of E having 10, each revolution of D produces 12 revolutions of E.
The wheels m and n transmit to o the same number of revolutions made by E, so
as to have the minute-hand, which is affixed to o, making one revolution every
hour. From these arrangements, it results that the minute-hand makes 4 x 12=48
revolutions, that is to say, 2 days by each revolution of B, and that the watch will
work 40 days with a spring R having 20 windings.
The wheels k and are intended to set the hands by means of the squared pin K.
They may be so placed as to be moved by a stem located in the pendant.
The ring J surrounds the whole work and bears a circular notch J upon
which is affixed a bezel U with glass U. This latter replaces the false-case of the
watch.

Q and A.
The wheel m, drives, by means of a transmitting wheel n, the cannon-wheel o
bearing the minute hand W.
The cannon-wheel O (with 72 teeth) which carries the hour-hand V, gears into
the pinion of wheel n, provided with 6 teeth.
As wheel B has 40 teeth, and wheel C 10, each revolution of B produces
4 revolutions of C, that is to say, of wheel D. This latter being provided with
120 teeth and the pinion of E having 10, each revolution of D produces 12 revolu-
tions of E. The wheels m and n transmit to o the same number of revolutions
made by E so as to have the minute hand, which is affixed to o, making one
revolution every hour.
From these arrangements, it results that the minute-hand makes 4 × 12 = 48
revolutions, that is to say, 2 days by each revolution of B, and that the watch will
work 40 days with a spring R having 20 windings.
The wheels k and I are intended to set the hand by means of the squared pin K.
They may be so placed as to be moved by a stem located in the pendant. The
ring J, surrounds the whole work and bears a circular notch J upon which is
affixed a bezel U, with glass U¹. This latter replaces the false case of the watch.
With a view to simplify the watch, the ring J may be suppressed, and the pro-
jection J¹ replaced by a special bridge screwed upon the plate Q. For the same
purpose the winding up of the watch may be obtained by turning the axis C of
wheel D, by the help of a key, and the setting of the hands by turning the central
pin, bearing the hands, by the help of a key, with a view to suppress the square K
and the wheels k, l, m.
Having now described the nature of my invention, and in what manner the same
may be performed, I declare that I claim :-
=
1st. In watches (or clocks) the arrangement of a mainspring having one of its
ends affixed to the plate bearing the works and its other to the hub of a wheel
placed under the centre of the dial, said wheel driving a watch or clock-work of
any kind, and the cannons bearing the hour hand, minute hand, and seconds hand,
traversing the hub of said wheel, substantially as described.
2nd. The recessed plate A, with fillets a and cannon A³, in combination with the
spring R and wheel B with hub B¹, acting upon a watch work of any kind and
provided with any winding-up mechanism, as and for the purposes set forth.
3rd. In watches, the combination of the plate A, bearing the mainspring and the
wheel B, with a plate Q bearing the other parts of the watch-work, and with
a ring J surrounding the whole work and bearing a bezel U with a glass U¹, as
set forth.
4th. The watch-work substantially as shewn and described, consisting of the
wheel D (driven by means of the click wheel d and click e) wheels E, F, G and H,
and balance wheel I, supported by plate Q, and bridges E, F, G, H' and I', and
of the wheels m, n, O and o, placed between Q and A.
5th. In watches, the combination of a mainspring affixed to the plate and driving
watch work of any kind, provided or not with hands.
