I, ALFRED MANASSÉ, of 12, Rue St. Charles à Enghien-les-Bains (Seine-et-
Oise), in the Republic of France, Merchant, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a perpetual calendar, characterised by its special com-
bination with a watch or like article.
My improved combination of a perpetual calendar and watch will be clearly
understood from the following description, reference being had to the annexed
drawings which illustrate, by way of example, one construction of my invention,
and in which:-
Figure 1 shows, in front view, my calendar applied to the case of a watch.
Figure 2 shows in elevation the mechanism operating the calendar.
Figure 3 shows the same mechanism in plan.
In all the figures, like letters of reference indicate similar parts.
My combined watch and calendar comprises a cover formed by a glass v, held
by a hinged frame u, in such a manner as to be easily opened; over the watch
movement there is a central disc r, on which is described, near its edge, a circle t;
another concentric circles which is independent and fixed, surrounds this arrange-
ment.
'
The larger circles bears signs representing the days of the week, and the inner
circle t bears numerals representing the days of the month.
On the central disc r are indicated the twelve months of the year, showing also
the number of days in each month.
The circle which bears the days of the month, being movable, may always be
adjusted so that the first day of the month agrees with the day of the week marked
on the circles. The movement or adjustment is effected by means of a small
button placed on the disc.

calendar is then regulated for one month.
This much being explained: the operation of the calendar is effected by the
movement of the watch, which causes the pointer / indicating the days of the
month to move over a division representing one day every twenty four hours, as
follows::
:-
On the rod a of the staff or central axis of the watch is arranged a pinion b
having. eight teeth, driving a wheel c having 32 teeth and turning on a pin d
mounted in the inner case or other suitable part. The wheel c carries a pinion e
having eight teeth, which operates a flat wheelf having 48 teeth, and rotating on
a supporting screw g. The wheel makes one turn per day and carries a pin h
engaging in a star wheel i having 35 teeth and provided with a barrel j turning

is held by a detent spring k screwed on to the inner case or plate.
The pointer indicating the days of the month is mounted on the barrel j of the
wheel in such manner as to be carried round by this barrel.
The pointer m indicating the months, which is independent of the clockwork
movement, is mounted loosely on the barrel j, and held by a friction spring of
any suitable construction placed under the disc r.
Obviously I may vary the construction and details of my invention in numerous
ways without departing from the nature or principle of my invention.

Improvements in or connected with Watches and the like.
I, ALFRED MANASSÉ, of 12, Rue St. Charles a Enghien-les-Bains, (Seine-et-
Oise), in the Republic of France, Merchant, 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 a perpetual calendar, characterized by its special com-
bination with a watch.
My improved combination of a perpetual calendar and watch will be clearly
understood from the following description, reference being had to the drawing left
with my Provisional Specification which illustrates by way of example one con-
struction of my invention and in which:-
Figure 1 shows, in front view, my calendar applied to the case of a watch.
Figure 2 shows in elevation the mechanism operating the calendar.
Figure 3 shows the same mechanism in plan.
Figure 4 shows a front of the mechanism of the calendar, this calendar having
been taken off to enable the mechanism to be seen.
Figure 5 is a vertical section of the arrangement.
Figure 6 is a detailed elevational view of the portion of the calendar having
the months and dates, this part is arranged to revolve upon a plate.
Figure 7 is a side elevation corresponding to Figure 6.
Figure 8 is a section underneath the plate and corresponding to Figures 6 and 7.
Figure 9 shows separately a ring fixed to the plate of the calendar by means
of two rods shown clearly in Figure' 10.
Figure 10 is an edge view corresponding to Figure 9.
In all the figures, like letters of reference indicate similar parts.
My combined watch and calendar comprises a cover formed by a glass v, held
by a hinged frame u, in such a manner as to be easily opened; over the watch
movement there is a central disc r, on which is described, near its edge, a circle t;
another concentric circle s, which is independent and fixed, surrounds this arrange-
ment.
The larger circles bears signs representing the days of the week, and the inner
circle bears. numerals representing the days of the month.
On the central disc r are indicated. the twelve months of the year, showing also
the number of days in each month.
The circle t, which bears the days of the month, being movable, may always be
adjusted so that the first day of the month agrees with the day of the week marked

page_text: on the circles. This movement or adjustment is effected by means of a small
button placed on the disc.
After having moved the circles as just stated, there still remains the month to
be indicated, which is done by means of a pointer m, moved by hand. The
calendar is then regulated for one month.
l
This much being explained; the operation of the calendar is effected by the
movement of the watch, which causes the pointer indicating the day of the
month to move over a division representing one day every twenty four hours as
follows:
On the rod a of the staff or central axis of the watch is arranged a pinion b
having eight teeth, driving a wheel c having 32 teeth and turning on a pin d,
mounted in the inner case or other suitable part. The wheel c carries a pinion e
having eight teeth which operates a flat wheel f having 48 teeth rotating on a
supporting screw g. The wheel f makes one turn per day and carries a pin h
engaging in a star wheel with 35 teeth provided with a barrel j turning on the
extremity of the staff a which forms a pin or pivot therefor. The wheel i is held
by a detent spring k screwed on to the thin plate.
The pointer indicating the days of the month is mounted on the barrel ; of the
wheel in such manner as to be carried round by this barrel.
The pointer m indicating the months, which is independent of the clockwork
movement is mounted loosely on the barrel j, and held by a friction spring of
any suitable construction placed under the disc r.
marking the days
The hand
The relation of the watch work movement with the hand
of the month upon my improved calendar is as follows.
only is
dependent upon the movement of the watch. The hand m is displaced by hand
in order to mark the current month. The wheel b having 8 teeth, and being
rigidly connected with the arbor of the large hand of the watch, making 1 revolu-
tion per hour, this said wheel b will thus itself make 1 revolution in 1 hour. The
wheel having 8 teeth, making 1 revolution in 1 hour and driving the wheel c
having 32 teeth this wheel c will thus make 82 = 14 revolution per hour, that is
to say 1 revolution in 4 hours. The wheel c being rigidly connected with the
pinion e having 8 teeth this pinion will thus effect 1 revolution in 4 hours, the
pinion e with 8 teeth making 1 revolution in 4 hours, the pinion f gearing there-
with and having 48 teeth will make 4 × =. revolution in 1 hour. That is
to sav 1 revolution in 24 hours. The wheel f making 1 revolution in 24 hours,
its pin h will at midnight come in contact with the wheel i having 35 teeth, and
will cause it to advance by tooth. As the dial of the calendar is divided into
.
35 equal parts forming equal sectors, the wheel to the spindle of which is rigidly
fixed the hand indicating the days of the month will advance by one division, that
is to say, one day. As there are never more than 31 davs in a month there will
be only 31 divisions out of the 35 indicated upon the dial of the calendar. • Upon
reaching the end of the month, the calendar is regulated by hand as herein before
stated, and this calendar will indicate during the whole month the days of the
month by means of the hand actuated by the clockwork movement as shown in
the annexed drawing.
Viewed from the front, my improved calendar-watch presents only an ordinary
appearance that is to say a dial divided into 12 hour spaces in the ordinary way
comprising a short hand for the hours and a long hand for the minutes. In con-
nection with the movement of the watch, it is only with the long hand that we
are concerned as regards the hand for showing the days of the month, because
it is the arbor of this long hand which traverses the whole thickness of the watch,
having fixed to it at the back of the watch the pinion b. Upon this arbor there is
also mounted loosely the star wheel i as explained above, which carries the barrel
or sleeve j, upon which is keyed the hand for the days of the month which is
arranged at the back of the watch.
Obviously I may vary the construction and details of my invention in numerous
ways without departing from the nature or principle thereof.

page_text: "Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
A perpetual calendar placed in the cover of a watch, on the clock-work move-
ment, and having the staff of the watch as centre; this calendar having an inde-
pendent and fixed circle s, on which are shown the days of the week, and a circle t
for the days of the month, fixed to a disc r, on which are inscribed the months
of the year; this calendar being set for a month by turning, by means of a
button, the circle t of the days of the month so as to make the first day of the
month correspond with the day of the week, then by moving by hand the inde-
pendent hand m until it is opposite the month marked on the disc r; the calendar
thus constituted and being set for a nionth, the days and the days of the months are
indicated automatically by a hand fastened on to the staff a of the clock work
movement which, by means of a train of gear wheels and a disengaging tongue
causes the said indicating hand to advance one division every 24 hours, the whole
combined and arranged substantially as above described with reference to the
drawing.
