page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of September, in the
year of our Lord One thousand eight hundred and seventy-five,
in the thirty-ninth year of Her reign, did for Herself, Her heirs and
successors, give and grant unto me, the said Benjamin Joseph Barnard
Mills, Her special license, that I, the said Benjamin. Joseph Barnard
Mills, my executors, administrators, and assigns, or such others 'as I,
the said Benjamin Joseph Barnard Mills, my executors, admini-
strators, 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, usc, 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 to me from abroad by Henri Jacot-Burmann, of
Bienne, in the Canton de Berne, in the Swiss Confederation, upon the
condition (amongst others) that I, the said Benjamin Joseph Barnard
Mills, my executors 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
O 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 Benjamin Jóseph Barnard Mills, do
hereby declare the nature of the said Invention, and in what manner
5 the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had
to the Drawings hereunto annexed, which are drawn to a scale double
that of the real size of the watch, and of which Figure 1 represents a
diagram of the back, and Figure 2 a diagram of the face gearing:-
The Invention has for its object improvements in watches, whereby
their manufacture. is faciliated and cheapened, and relates to the
employment of a peculiar arrangement of gearing, whereby keyless
watches with anchor escapements may be made of small or ladies' size.
The spring barrel has 128 teeth; the first wheel has 84 and the pinion
58 teeth or leaves; the second wheel has 72 teeth and the pinion 7 teeth
or leaves; the escapement wheel has 15 teeth and the pinion 6 teeth
or leaves; the minuto wheel has 60 tecth and the minute wheel

page_text: First. To transmit to the escapement a greater force by the suppression
of a wheel.
Second. To enable a larger spring barrel to be employed with a
weaker and longer spring, capable of greater development, having 17
turns in the barrel, and the axis of the barrel being capable of being
wound eight and a half turns.
Third. To employ more easily an anchor escapement of greater height
and size.
'
Fourth. A greater simplicity in the mechanism for winding, and
above all, in setting the hands.
These various simplications render the manufacture of the watch
more easy and less costly than watches constructed as heretofore.
Having thus described the nature of the said Invention, and the mode
in which the same is carried into effect, I would have it understood that
what I claim as the said improvements in watches is, the peculiar
arrangement of gearing herein shown and described by which the
advantages above described are obtained.
In witness whereof, I, the said Beniamin Joseph Barnard Mills,
have hereunto set my band. and seal this Fourth-day-of March,
in the year of our Lord One thousand eight hundred and
seventy-six.
