CERTAIN IMPROVEMENTS IN WATCHES AND OTHER TIME-KEEPERS.
Year: 1855

page_text: LETTERS PATENT to Gustavus Huguenin, of Greek Street, in the County
of Middlesex, Watch Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN WATCHES AND OTHER TIME-KEEPERS.
Sealed the 20th March 1856, and dated the 26th September 1855.
PROVISIONAL SPECIFICATION left by the said Gustavus Huguenin at
the Office of the Commissioners of Patents, with his Petition, on the
26th September 1855.
I, GUSTAVUS HUGUENIN, of Greek Street, in the County of Middlesex,
Watch Manufacturer, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN WATCHES AND OTHER TIME-KEEPERS" to be as follows
(that is to say)-
My Invention, which has reference to a new form of apparatus for winding
up and setting the hands of a watch or other time-keeper by the pendant, by
which means the employment of a key is dispensed with, is carried into effect
as follows:-I cause the pendant to be traversed by a pinion, the projecting
part of which forms a knob that can be turned by the hand, and the lower
part adjusts itself to a wheel which is furnished with a double set of teeth or
cogs. The one set of cogs acts upon the barrel wheel (through the inter-
vention of any suitable mechanism), and serves to wind up the watch or time-
keeper ;
the other set of cogs acts upon the minute wheel, and serves to adjust

page_text: the hands of the watch, but this set is only brought into action when the
toothed wheel is detached from the barrel wheel, and brought to bear on the
minute wheel through the medium of a moveable bridge, which is attached to
its axis. and actuated a second knob outside the time-keener
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Gustavus Huguenin in the Great Seal Patent Office on the
26th March 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GUSTAVUS
HUGUENIN, of Greek Street, in the County of Middlesex, Watch Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of September, in the year of our
Lord One thousand eight hundred and fifty-five, in the nineteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Gustavus Huguenin, Her special licence, that I, the said
Gustavus Huguenin, my executors, administrators, and assigns, or such others
as I, the said Gustavus Huguenin, 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 "CERTAIN
IMPROVEMENTS IN WATCHES AND OTHER TIME-KEEPERS," upon the condition
(amongst others) that I, the said Gustavus Huguenin, my exccutors or
administrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe 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.
NOW KNOW YE, that I, the said Gustavus Huguenin, 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 follow-
ing statement, reference being had to the accompanying Drawings (that is
to say)-
My Invention, which has reference to an improved construction of mecha-
nism for winding up and setting the hands of watches and other time-keepers,
is carried into effect as follows:-I cause the pendant to be traversed by a

page_text: pinion, the spindle of which is made to terminate in a knob for the convenience
of being readily turned by the hand when required; in connection with which
arrangement I adjust a wheel, furnished with a double set of depths or teeth,
one set taking into and receiving motion from the pinion, whilst the other set
is made to act upon the barrel wheel through the intervention of a coupling
wheel or other suitable mechanism, so as to wind up the watch or other
time-keeper, or may be brought to bear upon the minute wheel through
similar intervening mechanism for the purpose of setting the hands, the said
double-toothed wheel being only brought to bear upon the minute wheel
when it is detached from the barrel wheel through the medium of a move-
able bridge, which is attached to its axis, and actuated by a second knob or
stud on the outside of the watch or other time-keeper.
But in order that this my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it by the aid of the
accompanying Drawings, reference being had to the letters and figures thereon
marked (that is to say).
Fig. 1 represents an edge view of a watch with my improvements attached;
Fig. 2, a front elevation with the dial plate or face removed, showing the
mechanism in gear with the barrel wheel; Fig. 3, a corresponding view with
part of the face removed, showing the mechanism in gear with the hands for
the purpose of setting the same; Fig. 4, a view with the wheel-work removed,
showing the position of the moveable bridge; Fig. 5, a view with the outer
case and works removed; Fig. 6, a transverse vertical section of the same;
Fig. 7, a top or plan view of the moveable bridge, separately shown; Fig. 8,
a similar view of the double-toothed wheel; and Fig. 9, a side elevation of
the same. In each Figure the same letters of reference denote similar corre-
sponding parts. a, a, outer case; b, b, pendant; c, c, pendant knob; d, d,
pinion; e, e, shaft or spindle connecting the said pendant knob and pinion;
ff, double-toothed wheel; 9, pivot centre upon which it turns; h, h, move-
able bridge or lever, turning upon the same centre on which the double-toothed
wheel revolves; i, i, bridge or coupling wheels centred upon the projecting
ends of the bridge or lever, as represented at j, j; k, spring for keeping the
bridge or coupling wheel in gear with the barrel wheel; 1, stud or pin for
releasing the bridge wheels from the barrel, and throwing them in with
the minute wheel; m, m, barrel wheel; n, and n¹, spring and catch for retaining
the barrel or main spring in its position when wound up; o, minute wheel;
p, p, fixed bridge or cock securing the barrel. The operation of winding up
and setting the hands of watches or other time-keepers of my improved con-
struction is effected by simply turning the pendant knob c from left to right
gear

page_text: for winding up the watch, whilst the setting or moving of the hands requires
the stud or pin 7 to be pressed at the same time that the pendant knob c is
turned in either direction as required.
Having now fully described the nature of this my said Invention, and the
manner in which the same is to be performed, I would have it clearly under-
stood that I do not intend to confine myself to the precise details herein-
before set forth, as the same might be varied without departing from the
general principle of these my said improvements; but that which I do claim
as new and of my said Invention is, the winding up and setting the hands of
watches, and other time-keepers through the intervention of the double-toothed
wheel and moveable bridge, in connection with the stud movement and
pendant knob, in the manner and for the purposes herein-before set forth.
and described.
In witness whereof, I, the said Gustavus Huguenin, have hereunto set
my hand and seal, this Twenty-fifth day of March, in the year of our
Lord One thousand eight hundred and fifty-six.
Witness,
GUSTAVUS HUGUENIN. (L.s.)
