PROVISIONAL SPECIFICATION.
An Improvement in Watches.
ROBERT TURNER Watchmaker 53 Princess Street Bury do hereby declare the
nature of my invention for AN IMPROVEMENT IN WATCHES to be as follows:-
:-
By fixing upon the escape wheel arbor or pivot a second wheel of 48 teeth which
gears with another wheel or pinion of 8 the result with the ordinary train of 18,000
the pinion of eight makes a complete revolution per second.

COMPLETE SPECIFICATION.
An Improvement in Watches.
ROBERT TURNER Watchmaker 53 Princess Street Bury Lancashire do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, 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.
An ordinary English lever or cylinder movement (or any movement) of a suitable
calliper for the purpose.
The pillar plate is of an extra thickness where required to provide the space for an
extra wheel with suitable pinions composes a train to drive an extra seconds hand, at
the rate of once per second (or one revolution per second) the usual or actual
seconds 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 wheel 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 but carrying 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 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 rotatales at the same rate as the escape pinion and the
advantage derived is that the action of the watch (or escapement) is less interfeared
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 D and on this pivot A the extra
train wheel B is colleted friction tight.
The escape pinion A revolves 10 times per minute and carries the extra wheel B
at the same rate the extra wheel B gears with another pinion Cacting in its periphery
or teeth this pinion C carries the decimal hand and its train should be . the No. of
teeth contaned in the extra decimal train wheel B thereby driving the extra decimal
hand 60 revolutions per minute a small extra dial is placed on the face of the watch
dial similar to a small seconds dial in ordinary watches the dial is divided into 60 100
or any number as the case may be. A specially constructed stop work is employed
o enable the operator to stop it on an extra plan wheel fited tight on decimal pinion,
he object of stopping watch on the plan wheel is to enable the operator to stop the

page_text: watch between its beats (or jumps) thereby obtaining a more exact observation for
scientific or racing purposes &c. as it quite possible to stop the watch to go of a
second.
Having now particularly described the nature of my said invention and the manner
the same is to be, I declare that what I claim is
A complete revolution per second obtained from third or fourth wheels or scape
wheel pinion above the pillar plate or top plate as the case may be.
