SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 4th September 1865.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "AN IMPROVED METHOD OF WINDING UP WATCHES AND OTHER TIMEKEEPERS,"
to be as follows:-
This Invention consists in winding up watches and timekeepers by simply
opening and closing the case. Thus, for example, by opening and closing the
case five times the watch will be wound for 24 hours, ten times for 48 hours,
and even for eight days by opening and closing the case 40 times. The
opening and closing may be effected indefinitely without injury or incon-
venience to the watch.
This Invention is applicable to all watches, but more especially to those in
which the hinge of the case is in five parts. The central part forms a lever,
which comes in contact with the outer end of a rod fixed to a block supported
by the ratchet, and movable upon the pivot of the axis of the barrel. These
parts produce a to-and-fro motion, which by means of two pauls drive round
the barrel, and consequently wind up the watch.

page_text: To avoid too great tension of the spring from too frequently opening and
closing the case, a Philippe spring, well known to all watchmakers, is used
to throw off the winding gear when the watch is fully wound.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 3rd March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of September, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Archibald Brooman, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such others
as I, the said Richard Archibald Brooman, 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 METHOD OF WINDING UP WATCHES AND OTHER TIMEKEEPERS,"
(communicated to me from abroad by Robert Theurer, senior, and Robert
Theurer, junior, of Chauds de Fonds, Switzerland,) upon the condition
(amongst others) that I, the said Richard Archibald Brooman, 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 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.
P
NOW KNOW YE, that I, the said Richard Archibald Brooman, 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
by the following statement thereof, reference being had to the Drawings here-
unto annexed, that is to say :-
This Invention consists in winding up watches and other timekeepers by

page_text: simply opening and closing the case. Thus, for example, by opening and
closing the case five times the watch will be wound for twenty-four hours, ten
times for forty-eight hours, and even for eight days by opening and closing
the case forty times. The opening and closing may be effected indefinitely
without injury or inconvenience to the watch.
The Invention is applicable to all watches, but more especially to those in
which the hinge of the case is in five parts. The central part forms a lever,
which comes in contact with the outer end of a rod fixed to a plate supported
by the ratchet wheel, and movable upon the pivot of the axis of the barrel.
These parts produce an oscillating motion, which by means of two pauls drives
round the barrel, and consequently winds up the watch.
To avoid too great tension of the spring from too frequently opening and
closing the case, a Philippe spring, well known to all watchmakers, is used
to throw off the winding gear when the watch is fully wound.
Figure 1 of the accompanying Drawings is a back view on an enlarged
scale of a watch constructed according to this Invention with the cap open;
Figure 2 is a front view with the dial plate removed; Figure 3 is a side view
of the hinge of the case; Figure 4 represents the mechanism which winds up
the watch.
The central part of the hinge forms a lever a, which comes in contact with
the outer end of a rod 6 fixed to a plate c, supported by the ratchet wheel r,
and movable upon the pivot of the axis of the barrel. These parts produce
an oscillating motion, which by means of two pauls d drives round the barrel,
and consequently winds up the watch. To move the pointers I fit a pinion g
to the rod h of the "secret," which on being drawn outwards puts this pinion
in gear with a wheel i, which transmits the movement to the pointers.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim winding up
watches and other timekeepers, substantially as herein-before described with
reference to the accompanying Drawings, by opening and closing the case.
.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Second day of March, One thousand
eight hundred and sixty-six.
