IMPROVEMENTS IN MECHANISM FOR WINDING AND FOR SETTING THE HANDS OF KEYLESS TIMEKEEPERS
Year: 1877

page_text: LETTERS PATENT to Henry Stuart, of Liverpool, in the County of Lancaster,
Watch Manufacturer, and George Daniels, of the same Place, Watchmaker, for
the Invention of "IMPROVEMENTS IN MECHANISM FOR WINDING AND FOR
SETTING THE HANDS OF KEYLESS TIMEKEEPERS."
Sealed the 13th October 1877, and dated the 19th April 1877.
PROVISIONAL SPECIFICATION left by the said Henry Stuart and George
Daniels at the Office of the Commissioners of Patents on the 19th April
1877.
HENRY STUART, of Liverpool, in the County of Lancaster, Watch Manufacturer,
and GEORGE DANIELS, of the same Place, Watchmaker. "IMPROVEMENTS IN
MECHANISM FOR WINDING AND FOR SETTING THE HANDS OF KEYLESS TIMEKEEPERS."
The object of this Invention is to provide simple, durable, and compact mechanism
by which the two operations of winding up and setting the hands of timekeepers
can be effected by turning a fluted stem in the pendant. The said mechanism is
well adapted for application to timekeepers now in use.
For the above purpose we employ in combination a stem free to turn and slide
inwards and outwards, and an annular wheel with inside and outside teeth. When
in ordinary position the inside teeth of the annular wheel take into the teeth of a
wheel secured directly to the fusee or spring arbor, and the watch is wound up by
turning the stem, which has at its inner end a small toothed wheel which takes into
the teeth of the annular wheel. When the stem is depressed the annular wheel is
caused to slide towards the centre of the timekeeper and the outside teeth come
into gear with the teeth of a wheel on the arbor carrying the minute hand, the
hands can then be set by turning the stem.
When the annular wheel is in gear with the wheel on the minute hand arbor the
wheel on the fusee or spring arbor is in the centre of such annular wheel and out of
gear with it. After setting the hands the stem is returned to its original position
by a spring.

page_text: If desired, a bolt or its equivalent may be used to keep the stem in position for
winding so as to prevent its being depressed accidentally and acting on the hands.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Stuart and George Daniels in the Great Seal Patent Office on
the 19th October 1877.
HENRY STUART, of Liverpool, in the County of Lancaster, Watch Manufacturer,
and GEORGE DANIELS, of the same Place, Watchmaker. "IMPROVEMENTS IN
MECHANISM FOR WINDING AND FOR SETTING THE HANDS OF KEYLESS TIMEKEEPERS."
The object of this Invention is to provide simple, durable, and compact mechanism
by which the two operations of winding up and setting the hands of timekeepers
can be effected by turning a fluted stem in the pendant. The said mechanism is
well adapted for application to timekeepers now in use.
For the above purpose we employ in combination a stem free to turn and slide
inwards and outwards, and an annular wheel with inside and outside teeth. When
in ordinary position the inside teeth of the annular wheel take into the teeth of a
wheel secured directly to the fusee or spring arbor, and the watch is wound up by
turning the stem, which has at its inner cnd a small toothed wheel which takes into
the teeth of the annular wheel. When the stem is depressed the annular wheel is
caused to slide towards the centre of the timekeeper, and the outside teeth come
into gear with the teeth of a wheel on the arbor carrying the minute hand; the
hands can then be set by turning the stem.
When the annular wheel is in gear with the wheel on the minute hand arbor, the
wheel on the fusee or spring arbor is in the centre of such annular wheel and out of
gear with it.
After setting the hands the stem is returned to its original position
by a spring.
If desired, a bolt or its equivalent may be used to keep the stem in position for
winding to prevent its being depressed accidentally and acting on the bands.
Figs. 1 and 2 are views of such portion of a watch or timekeeper as is necessary
to illustrate our improvements. Fig. 1 shows the mechanism in position for winding,
and Fig. 2 in position for setting the hands.
1 is the arbor of the going barrel or fusee, fitted with the toothed wheel 2; 3 is
the arbor of the minute hand carrying the wheel 4; 5 are wheels and pinions for
communicating motion to the hour hand; is an annular wheel with teeth on the
inside and outside; 7 is an intermediate wheel; 8, 9, are guides for the annular
wheel; 10 is a spring to cause the annular wheel to take the position shown in
Fig. 1 11 is the winding stem provided with a toothed wheel 12 at its inner end
to take into the teeth of the annular wheel. The stem 11 is free to slide in the
hollow sleeve 13 of the pendant 14, so as to give a to-and-fro motion to the annular
wheel 6, and cause it to gear either with the wheel 2 of the going barrel or fusee
arbor, or with the intermediate wheel 7, which gives motion to the wheel 4 on the
minute arbor. A bolt or catch 15 retains the stem 11 in position shown in Fig. 1
unless forcibly pushed into the position shown in Fig. 2.
It will be evident that if the stem is turned when in the position shown in Fig. 1
that the watch or timekeeper will be wound up, and that if it is turned when in
the position shown in Fig. 2 the hands will be set.
Having now described the nature of the said Invention in such manner that
others will be enabled to carry our improvements into effect, we claim,--the improved

substantially as set forth and illustrated.
In witness whereof, I, the said Henry Stuart, have hereunto set my hand and
seal, the Seventeenth day of October, in the year of our Lord One thousand
eight hundred and seventy-seven.
