TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HECTOR
AUGUSTE DUFRENE, of No. 10, Rue de la Fidélité, Paris, in the Republic
of France, and 4, South Street, Finsbury, London, Civil Engineer and

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of May, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Hector Auguste Dufrené, Her special licence
that I, the said Hector Auguste Dufrené, my executors, administrators,
and assigns, or such others as I, the said Hector Auguste Dufrené, 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 time
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 "IMPROVEMENTS IN
WATCHES," (a communication from Monsieur François Riondey, a person
resident at No. 11, Quai de Strasbourg, Besançon, in the Republic of
France,) upon the condition (amongst others) that I, the said Hector a
Auguste Dufrené, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and scals, should par-
ticularly 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 å
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Hector Auguste Dufrené, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and

page_text: by the following statement, reference being had to the Drawing hereto
annexed, and to the figures and letters marked thereon, that is to
say:-
The Invention communicated to me consists in placing the escape-
ment of watches in sight on the dial in such a manner that all parts of
tho escapement may be visible instead of being hidden, as they now
arc.
To carry out the Invention I can employ any suitable kind of escape-
ment. The cock may be of any suitable form, that shewn on the
Drawing and marked A being an example. Only the parts of the
escapement are visible. The cock is placed on an enamelled bottom,
but in lieu of an enamelled bottom an open or closed plate may be
employed.
When employing a kind of escapement in which a closed plate is
necessary the escapement wheel is carried on a moveable carriago
arranged so as to recede from or approach to the escapement.
The arrangements of the other parts of the works of the watch do not
require any material alteration from those in the ordinary mode of
construction.
What I claim is, the manufacture of watches with the escapement
placed on the dial so as to be visible from the outside, as herein-before
described.
In witness whereof, I, the said Hector Auguste Dufrené, have
• hereto set my hand and scal, this Twenty-eighth day of October,
in the year of our Lord One thousand eight hundred and seventy-
two.
