An Improvement in Watches.
ROBERT TURNER 49 Princess Street Bury Lancashire Watchmaker do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to obtain a more minute division of time than is
usually obtained and the means employed are as follows, also a greater certainty
of the performance of watch when the operator relieves the roller (rough edge) by
the ordinary stop work (in cases).
An ordinary English lever or cylinder movement (or any movement) of a suitable
caliper for the purpose.
The pillar plate is of extra thickness to provide space for an extra wheel with
suitable pinion compose a train to drive an extra second hand at the rate of once
per second (or one revolution per second) the usual or actual second hand still
being employed to revolve once per minute as in any ordinary watch.
The extra train of wheels to drive the extra seconds hand hereafter called the
decimal hand may be applied from the third or fourth wheel or from the escape
pinion a in each case a similar extra train would be employed above the pillar plate
or above the top plate as the case may be but of course with more wheels and
pinions when the former method is decided upon. The watch has a pinion of
seven run into the fourth wheel similar to the escape pinion A & wheel B above
the pillar plate of watch and under the dial and in some cases above the top plate,
and under another dial or at the back of the watch, under the dome. The wheel B.
may be sunk in the pillar plate or top plate or not, as required, it will be understood
that the pinion rotates at the same rate as the escape pinion and the advantage
derived is that the action of the watch (or escapement) is less interfered with than
on the following plan.
2nd plan. The escape wheel pinion A of watch is of extra length and the
bottom pivot exceeds in length the thickness of pillar plate and on the pivot A.
the extra train wheel B. is collited friction tight. The escape pinion A revolves
The extra
ten times per minute and carries the extra wheel B. at the same rate.
wheel B. gears with another pinion C. acting in its periphery or teeth. This
pinion C. carries the decimal hand. And its train should be one sixth (t) the
number of teeth contained in the extra decimal wheel B. thereby driving the extra
decimal hand 60 revolutions per minute. A small extra dial is placed on the face
of watch dial similar to a small seconds dial in ordinary watches.
The dial is divided into 10th 16th 20th or 32nd part of a second or any number
as the case may be. Also a great wheel or escape wheel E is now employed to
divide the time to 10th 16th 20th or 32nd part of a second as is required from
time to time. The wheel is calculated according to number of beats required by
rule 3 times the number of beats required will give the number of teeth to be cut
in the escape wheel. Also an extra roller H with rough edges is placed upon
balance staff G. and between ordinary roller I and balance wheel F. so as to be
more certain of the watch starting when drawn off by the stop wire.

page_text: Having now particularly disclosed the nature of my said invention and the
manner the same is to be performed I declare that what I claim is
A complete revolution per second obtained from the escape pinion A with extra
wheel B. (and extra large and high numbered escape wheel teeth, E.) and decimal
pinion C. also plain rough edged roller H (with drawings).
Dated this 14th day of October 1893.
