IMPROVEMENTS IN KEYLESS WATCHES
Year: 1865

page_text: LETTERS PATENT to Henry Chevob, of No. 32, Ely Place, Holborn, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN KEYLESS
WATCHES."
Sealed the 8th September 1865, and dated the 15th March 1865.
PROVISIONAL. SPECIFICATION left by the said Henry Chevob at the
Office of the Commissioners of Patents, with his Petition, on the 15th
March 1865.
I, HENRY CHEVOB, of No. 32, Ely Place, Holborn, in the County of Mid-
dlesex, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN KEYLESS WATCHES," to be as follows:-
This Invention has reference to those watches known as keyless watches,
and consists in actuating the winding, square by means of the handle or bow
of the watch. Keyless watches are wound from the top by means of certain
mechanical arrangements actuated by a knob in the shape of a crown or some
other device instead of by a special watch key.
The object of this Invention is to simplify the means of winding the watch
by performing the same object with less mechanical arrangements. By this
Invention the pendant forms the key, the handle or bow being fixed as usual
to the knob or top of pendant, the pendant key works on the square of
the winding power of the watch direct, and on the bandle being turned the
watch is wound up. The key bandle, which forms the winding power, is made
in one piece, and the watch can be repaired by any ordinary workman by
simply unscrewing the handle from the top of the watch and taking out the
movement.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
CHEVOB, of No. 32, Ely Place, Holborn, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of March, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Chevob, Her special licence that I, the said Henry Chevob, my
executors, administrators, and assigns, or such others as I, the said Henry
Chevob, 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 "IMPROVEMENTS IN KEYLESS
WATCHES," upon the condition (amongst others) that I, the said Henry
Chevob, 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.
NOW KNOW YE, that I, the said Henry Chevob, 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:
This Invention has reference to those watches known as keyless watches,
and consists in actuating the winding square by means of the handle or bow
of the watch. Keyless watches are wound from the top by means of certain
mechanical arrangements actuated by a knob in the shape of a crown or some
other device instead of by a special watch key.
The object of this Invention is to simplify the means of winding the watch
by performing the same object with less mechanical arrangement. The key
handle, which forms the winding power, is made in one piece, and the watch
can be repaired by any ordinary workman by simply unscrewing the handle
from the top of the pendant and taking out the movement. This winder is a

page_text: substitute for a regular briguet key, and can be handled by the most unskilful
workman as well as by the most delicate lady without the least trouble. With
the crown system at present in use it requires nearly double the time to arrive
at the top of the clickwork. With my Invention the strength of a key shaped
to wind up any hard spring is far superior to a crown, which offers but little
hold to the fingers. This winder insures the greatest solidity by being fixed
on the square winder with a screw perforating it entirely, whereas the old.
system only allowed its being slightly screwed on the sides. Should the
watch require to be repaired the movement can be taken out of the case by
removing in one minute the screw fixing the key, and this without interfering
at all with the bow. In keyless watches as at present constructed the me-
chanism is so complicated that few watchmakers in the country would find
out how to deal with it, as the first thing to be done is to take off the bow in
order to arrive at an exceedingly small screw.
In the annexed Drawings the shape or configuration of the bow, pendant,
and handle are clearly shown in Figs. 1, 2, 3, 4, 5, and 6, by which it will
be,seen that the ornamental design is very little larger than the ordinary knob
at present in use. Fig. 7 shews a bow with crown system.
I do not confine myself to any particular shape or design, as any design or
configuration may be made applicable, as circumstances or fancy may dictate;
an initial letter, as is seen by reference to Fig. 6, can be made applicable
when desired.
Having now described the nature and object of my Invention, I declare
that what I claim and desire to be secured to me by the therein-before in part
recited Letters Patent is, the improvements in keyless watches substantially
as herein-before described and illustrated on Drawings, or any mere modi-
fication or imitation thereof.
In witness whereof, I, the said Henry Chevob, bave hereunto set my
hand and seal, this Fourteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-five.
