CERTAIN IMPROVE- MENTS IN OR ADDITIONS TO HOROLOGICAL MACHINES
Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PACE, of Bury Saint Edmunds, in the County of Suffolk, Clock and Watch
Maker, send greeting.
WHEREAS His most Excellent Majesty King William the Fourth, by
His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Fourteenth day of November, in the fourth year of
His reign, did, for Himself, His heirs and successors, give and grant unto
me, the said John Pace, His especial licence, that I, the said John Pace, my
exors, admors, and assigns, or such others as I, the said John Pace, my exors,
admors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England and Wales
and the Town of Berwick-upon-Tweed, my Invention for "CERTAIN IMPROVE-
MENTS IN OR ADDITIONS TO HOROLOGICAL MACHINES;" in which said Letters
Patent there is contained a proviso obliging me, the said John Pace, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same
is to be performed, and to cause the same to be enrolled in His Majesty's High
Court of Chancery within six calendar months next immediately after the date
of the said recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Pace, do hereby declare that the nature of my said Invention, and the

page_text: manner in which it is to be performed, is described and ascertained in the
following explanation thereof; that is to say:-
My Invention consists of a portable timepiece constructed in such manner
that, besides shewing the time in the usual way, the entire surface of the dial
can be illuminated so as to shew the time by night. An ornamental metal
or other case or frame encloses all the works and constructions, and every
apparatus connected therewith or belonging or necessary thereto. The move-
ment is a watch train upon a large scale, with any of the usual and known
balance scapements, and is fixed or attached to the lower part of the case
or frame (in like manner to the supposed movement demonstrated by the
letters A, A, in the Drawing in the margin hereof, or annexed hereto), or to
such other part of the said case or frame as to be screened and protected from
the heat arising out of the lamp herein-after mentioned. The said movement
is connected with the motion work of the hands by means of an endless cord
or chain marked B in the said Drawing, which passes over two pulleys, one
attached to the arbor of the centre pinion of the train, the other to the pinion
commonly known as the cannon pinion, which acts upon the motion work of
the hands, the former of which pulleys is shewn in the said Drawing by letter C,
and the latter in the said Drawing by the letter D. The motion work of the
hands is supported by or attached to a metal or other plate or bar, the same to
be fastened perpendicularly upon or into the case or frame, as shewn by
letters E in the said Drawing, or otherwise, as occasion may require. The
motion wheels are planted upon or supported a cock or raised bar screwed
or affixed to the said metal or other plate or bar, and marked by letter F in
the said Drawing, or in such other place or manner as may be best adapted
for the purpose designed. The motion is carried forward to the hands by
making the arbor of the said cannon pinion, and the socket of the hour wheel
connected therewith, of such length as to allow sufficient and proper space for
the light of the said lamp to act upon the said dial, as herein-after mentioned.
The dial is either of metal, glass, silk, paper, parchment, or other suitable
material, or a combination of all or any of them, so as to be transparent or
semi-transparent, and admit of light passing through it, and the figures or
characters and divisions upon the dial shewing the hours and minutes to be
either printed, or painted, or formed of metal or other proper substance, and
fixed to or placed upon or against the transparent part of the dial. An
opening in the frame or case herein-before mentioned admits of a fountain
lamp (illustrated by letters G and H in the said Drawing), with a floating or
other burner, which burner is situated in the unoccupied space left between
the motion wheels of the hands and the inner surface of the dial, and so

page_text: placed as to avoid injuriously heating any part of the said motion wheels or
other works connected therewith. The air which supplies the place of the oil
consumed is admitted by the tube which supports the burner, or by means of
another aperture or other apertures in the body of the lamp, or by all or any
of them. The light from the burner is, by means of reflectors properly placed
for the purpose, thrown and diffused equally and uniformly over the whole of
the surface of the dial, and in such manner as to prevent any shadow falling
thereon. The said reflectors may be adjusted to any place or places, or
combined in any manner with all or any of the constructions or operations
herein described or mentioned. To avoid the accumulation of heat within
from the flame of the lamp, an opening is provided at the upper part of the
case, which opening, when the lamp is not burning, can be closed by an
ornamented cover or slide.
In witness whereof, I, the said John Pace, have hereunto set my hand
and seal, the Twenty-sixth day of April, in the year of our Lord One
thousand eight hundred and thirty-four.
Signed, sealed, and delivered (being
first duly stampt), by the within-
named John Pace, in the presence of
JN CAMBRIDGE.
