COMPLETE SPECIFICATION filed by the said 'George Philcox at the Office
of the Commissioners of Patents, with his Petition and Declaration, on
the 9th March 1857, pursuant to the 9th section of the Patent Law
Amendment Act, 1852.
3: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
PHILCOX, of No. 7, Stebon Terrace, Stepney, in the County of Middlesex,
Chronometer Maker, send greeting..
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MARINE AND POCKET CHRONOMETERS AND OTHER TIMEKEEPERS," and have petitioned
Her Majesty to grant unto me, my executors, administrators, and assigns,
Her Royal Letters Patent for the same, and have made solemn declaration
that I verily believe myself to be the first and true Inventor thereof.
NOW KNOW YE, that I, the said George Philcox, do hereby declare that
the following Complete Specification, under my hand and seal, fully describes
the nature of my said Invention, and the manner in which the same is to be
performed (that is to say) :-

page_text: This Invention consists of a particular train of wheels applicable only to the
two-day marine chronometer and one-day pocket chronometer, as in the Draw-
ings hereunto annexed described; also a detent passing through from back
plate to motion work, with pinion fixed on pivot to work in minute wheel, in
order to set the hands of timepiece without opening the case.
The advantages from the aforesaid combination of improvements are sim-
plicity, correctness, durability, and cheapness; and much less liable to be put
out of order than the instruments now used.
The application of the detent to cabin timekeepers is of great utility, inas-
much as you can by that means set the hands without opening the face of the
timekeeper. When at sea in rough weather there is difficulty in setting the
hands of the timekeeper as now constructed.
Fig. 1 shews the sections of a marine chronometer with double cylindrical
spring, as described in my Patent dated the Twenty-fifth day of April, One
thousand eight hundred and forty-six. It also shews balance and escapement,
as described in my Patent dated the Thirteenth day of November, One
thousand eight hundred and fifty-two, with the arrangement of train as herein
specified.
Fig. 2, calliper for pocket chronometer; Fig. 3, calliper for marine chro-
nometer; Fig. 4, the face of a cabin timepiece in case, with eye and pin to
fix in staple; Fig. 5, the back of case, shewing the two joints to screw to
cabin, and the two holes to wind up and set hands.
In witness whereof, I, the said George Philcox, have hereunto. set my
hand and seal,. this Ninth day of March, in the year of our Lord
One thousand eight hundred and fifty-seven.
