maker, for the Invention of "AN IMPROVED MECHANICAL ARRANGEMENT
FOR THE WINDING-UP AND THE SETTING OF THE HANDS OF WATCHES BY
MEANS OF THE HAR OR MED DR
Sealed the 22nd August 1862, and dated the 28th February 1862.
PROVISIONAL SPECIFICATION left by the said Pierre Destaing Azemar
at the Office of the Commissioners of Patents, with bis Petition, on the
28th February 1862.
I, PIERRE DESTAING AZEMAR, of Paris, France, Watchmaker, do hereby
declare the nature of the said Invention for "AN IMPROVED MECHANICAL
ARRANGEMENT FOR THE WINDING-UP AND THE SETTING OF THE HANDS OF WATCHES
BY MEANS OF THE KNOB OF THE PENDANT," to be as follows:-
The Invention relates to a mechanical arrangement for the winding-up and
the setting of the hands of watches by means of the knob of the pendant
instead of by a special watch key; the said mechanical arrangement, called
remontoir, forming part of the watch. The Invention is based on the appli-
cation for this purpose of an endless screw or screws and connecting pinion or
pinions in combination with a breguet key clickwork, and other suitable
parts, in such manner that by turning the said knob of the pendant the watch
may be wound up without acting on the hands, whereas by pressing at the
same time on a stud protruding through the rim of the watch, the turning of
the knob will, on the contrary, actuate the hands without any further winding
up the, watch. For this purpose the axis of the knob turns freely in the
pendant, and is provided, towards its lower end, with a spindle ending in a
rod, the further end of which passes through the bent part at the lower end of

page_text: the long arm of a three-armed lever turning on a pivot, one of the short arms
of which lever may be depressed from the outside of the watch by a stud
protruding through the rim of the watch and suitably connected to the said
short lever arm, by which means the endless screw or worm with which the
above-mentioned rod is provided is brought in gear with a pinion fixed on the
arbor of the minute hand, while at the same time the opposite short arm of
the three-armed lever lifts a button fixed to the upper part of a breguet key
clickwork, and thus liberates this upper part from the lower part of the said -
clickwork, to which lower part is fixed a hollow arbor carrying another worm
or endless screw in gear with a pinion fixed on the arbor of the main spring;
through this hollow arbor passes and turns freely the spindle fixed to the
pendant knob axis. Part of the said spindle is made square and glides in a
corresponding opening in the upper part of the clickwork and the button
thereof, thus causing this button and upper part to turn with the said spindle,
and consequently be dependent on and worked by the knob of the pendant.
Round part of the spindle is coiled a spiral spring pressing on the top of the
button for carrying the upper part of the click work in gear with the lower part
thereof, after the said upper part should have been lifted and liberated from
the said lower part, by pressing on the above-mentioned stud, the said lower.
part being further provided round its lower periphery with indentations in
which takes a click spring; consequently, whenever the knob of the pendant
be turned in the required direction, the endless screw of the hollow arbor will
cause the winding-up of the watch, whilst the endless screw of the rod will be
out of gear with the pinion actuating the watch hands; whereas by pressing
on the stud the hollow arbor will cease to be worked by the knob, whilst
the endless screw of the rod will be in gear with the pinion for the watch
bands, so as to allow of these latter being actuated by the knob of the
pendant

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PIERRE:
DESTAING AZEMAR, of Paris, France, Watchmaker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria; by Her Letters
Patent, bearing date the Twenty-eighth day of February, in the year of our: 35
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year of

page_text: Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Pierre Destaing Azemar, Her special licence, that I, the said
Pierre Destaing Azemar, my executors, administrators, and assigns, or such
others as I, the said Pierro Destaing Azemar, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "AN IMPROVED MECHANICAL ARRANGEMENT FOR THE WINDING-UP
AND THE SETTING OF THE HANDS OF WATCHES BY MEANS OF THE KNOB OF THE
PENDANT," upon the condition (amongst others) that I, the said Pierro
Destaing Azemar, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly describo
and ascertain the nature of the said Invention, and in what manner the same
was to be performed; and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
i
NOW KNOW YE, that I, the said Pierre Destaing Azemar, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement:-
The Invention relates to a mechanical arrangement for the winding-up and
the setting of the hands of watches by means of the knob of the pendant
instead of by a special watch key, thus entirely doing away with the use of this.
latter; the said mechanical arrangement, called remontoir, forming part of the
watch, and being contained with the ordinary movement in the casing of the
watch, so that at the outside a watch provided with this remontoir offers no
difference to an ordinary one, except the pendant knob and a small stud
protruding through the rim of the casing. The Invention is based on tho
application for this purpose of a three-armed or crutch lever, an endless screw
or screws for actuating the minute hand pinion and the main spring arbor, in
combination with a breguet key clickwork, and other suitable parts, in such
manner that by turning the knob of the pendant the watch may be wound up.
without acting on the hands, whereas by pressing at the same time on a
stud protruding through the rim of the watch the turning of the pendant knob
will cause the hands only to move, thus allowing the setting of the same as
required.
In order to make the Invention readily understood I will now give a full
description of the same, referring, thereby to the annexed Drawings, in both

page_text: Figures of which corresponding parts are indicated by the same letters of
reference.
Fig. 2 represents a watch provided with my improved remontoir, of which
latter Fig. 1 shows a separate view on a considerably increased scale in order
to allow of better distinguishing its various parts. The same consists essen-
tially of two distinct mechanical arrangements, which, when not connected
together, allow of winding-up the watch, and when connected, of setting the
hands.
in
r
A, A³, A2, is a three-armed or crutch lever, the lower end of the arm A of
which is provided with a knee or bent part B; this lever A, A³, A2, has its fulcrum
a, and may be acted upon from the outside of the watch by a stud p pro-
truding through a corresponding slit in the rim R of the watch, which stud p is
connected to the arm A³ by a small pin q, on which the same turns, or by other
suitable means, in such manner that by pressing on the stud p the lever A, A³, A2,
will turn slightly and assume the position A', B', marked in red ink in Fig. 1.
The knee or bent part B has a conical hole b, through which passes the lower
end of a rod E, provided with a worm or endless screw D, which worn, when
the lever arm A, B, is in the position marked A', B', is carried in the position
marked D', in gear with the pinion C of the minute hand arbor. The upper
end of the rod E forms part of a spindle K, K2, K³, cylindrical in K and K',
and of a square form in K³; the cylindrical parts K and K turning freely in
corresponding axial holes provided in the hollow arbor H, whilst the part K³
may glide up and down in a corresponding axial perforation provided in the
upper part F of a breguet key click work F, F, the cylindrical shank h, the
button P, and the pendant knob axis L, to which latter the upper end of the
spindle K, K, K³, is fixed, whilst a spiral spring N, inserted in the perforated
part of the axis L and coiled round the upper part of K³, presses on the top of
the button P. The hollow arbor H is provided with a worm or endless screw I
in gear with the pinion J of the main spring arbor. The upper end of the
arbor H is fixed to the lower part F of the breguet key clickwork F, F,
which part F is allowed to turn only in the required direction, and is prevented
from doing so in the opposite one by the effect of a spring G taking into
indentations or slits f provided in the periphery of the lower part F of the
clickwork, to the upper part F of which latter a button P is fixed by a cylin-
drical shank h, which shank is inserted in a corresponding hole provided in
the further end of the arm A² of the lever A, A³, A2, in such manner that when
the arm A³ of this lever is depressed, and consequently the opposite arm A
lifted, the same will carry with it the button P, and thus lift this latter into
the position P¹ marked in red ink in Fig. 1, and thereby put the upper part F

page_text: of the click work out of gear with the lower part F* of the same; whereas as
soon as the pressure on the arm A³ ceases, the spring N will carry the button P
to its original position, and thereby put the upper part F of the click work
again in gear with the lower part F2 of the same.
The mode of working of this arrangement will now be readily understood.
For winding-up the watch it will suffice to turn the pendant knob M in
the required direction, say, from left to right, which will cause the arbor II
and worm I to turn in the same direction, this worm I on its turn causing
the pinion J of the main spring arbor to turn till the watch will be wound up.
This latter being done, if it be wished to set the hands, it will be required only
to depress by means of the stud p the arm A³ of the crutch lever A, A³, A²,
so as to put the worm B in gear with the minute hand pinion C, and then turn
the knob M from left to right or from right to left, according to the direction
in which the hands require to be moved.
Having thus described and particularly ascertained the nature of my Inven-
tion, and the manner in which the same operates, I wish to add that I do not
intend to restrict or restrain myself to the exact arrangement above described,
as many variations may be made therefrom without departing from the main
feature or principle of acting of the same; but what I consider to be novel
and original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent is, 1ly, the general arrangement of my
improved remontoir, offering, 2ly, a combination of the above-described crutch
lever with a breguet key click work and suitable worms and other working
parts, so as to allow of effectuating at pleasure, by means of the pendant knob
and the stud p, either the winding-up of the watch or the setting of the hands
of this latter.
In witness whereof, I, the said Pierre Destaing Azemar, have hereunto
set my hand and seal, this Twenty-fifth day of August, in the year of
our Lord Eighteen hundred and sixty-two.
