PROVISIONAL SPECIFICATION left by the said David Hitchin at the
Office of the Commissioners of Patents, with his Petition on the
19th December 1859.
I, DAVID HITCHIN, of Coventry, in the County of Warwick, Watch-maker,
do hereby declare the nature of the said Invention for "AN IMPROVEMENT
IN THE CAPS OF WATCHES," to be as follows:-
My Invention of an improvement in watches relates to a novel mode of
constructing the caps of watches, whereby they will be enabled the more
effectually to exclude dust from the works.
The improvement consists in letting into the opening in the metal cap
above the balance-wheel a piece of flat or dome-shaped glass which will
permit of the works underlying the glass and also of the jewels in the top
plate being inspected without removing the metal cap; the attachment of
the metal cap to the plate is effected in the ordinary or any convenient
manner,

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said David Hitchin, in the Great Seal Patent Office on

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID

Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said David Hitchin, Her special license that I, the said David
Hitchin, my executors, administrators, and assigns, or such others as I, the
said David Hitchin, 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 IMPROVEMENT IN THE CAPS OF WATCHES," upon the condition (amongst
others) that I, the said David Hitchen, by an instrument in writing under my
hand and seal, 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 David Hitchin, 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,
reference being had to the Drawing hereunto annexed and to the letters and
figures marked thereon (that is to say):-
My Invention of "An Improvement in the Caps of Watches," relates to a
novel mode of constructing the caps of watches, whereby they will be enabled
the more effectually to exclude dust from the works.
The improvement consists in letting into the opening in the metal cap
above the balance-wheel a piece of flat or dome-shaped glass which will
permit of the works underlying the glass and also of the jewels in the top
plate being inspected without removing the metal cap, the attachment of
the metal cap to the plate is effected in the ordinary or any convenient
manner.
In the accompanying Drawing Fig. 1, is a plan view; Fig. 2, a side view;

page_text: and Fig. 3, a sectional view of one of my improved transparent dome caps; a
is the glass and 6 the metal frame in which the glass is fixed or secured in
the same way that an ordinary watch glass is usually secured in its
frame.
Having now described my improvement in watches and having explained
the manner of carrying the same into effect I claim as the invention secured
to me by Letters Patent as aforesaid constructing the domes or caps of watches
with a transparent or glass top so that some of the working parts may be
seen or inspected without removing the cap.
In witness whereof, I, the said David Hitchin, have hereunto set my
hand and seal, the Eighteenth day of June in the year of our Lord
One thousand eight hundred and sixty.
Witness,
WILLIAM JOSEPH RAIN,
