I, JOSEPH ROBINSON, of No. 4 Church Street, Maryport, in the County of
Cumberland, Gentleman, do hereby declare the nature of this Invention to be as
follows:-
This Invention relates to improvements in the construction of Keyless Watches,
whereby the exact time may be ascertained either in the dark, without looking at
the watch, without opening same, or without feeling the hands or pointers.
*
"
My improvements consist in such alteration of the winding apparatus, the cog wheel
and teething of the revolving plate or disc, as will allow the watch to run down at a
uniform rate of speed, corresponding with the time given by the watch. On its being
wound up, the number of "clicks" or beats caused by winding will correspond exactly
with the minutes elapsing since the watch was last wound up. Thus, given the time of
last winding up, say 12 midnight, take the watch and count the clicks or beats in
rewinding, say 240. This will give the time 4 a.m., and so on in proportion.
In long-winding watches, the regulation can be one
"click or beat per minute.
In short winders it can be arranged and regulated for two or three minutes by
adopting this principle, and the calculations giving the exact time, made accordingly.
Dated this 18th day of October 1886.

page_text: Improvements in the Construction of Keyless Watches.
I, JOSEPH ROBINSON, of No. 4 Church Street, Maryport, in the County of
Cumberland, Gentleman, 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:-
This Invention relates to improvements in the construction of Keyless Watches,
whereby the exact time may be ascertained either in the dark, without looking at the
watch, without opening same, or without feeling the hands or pointers.
It consists in the construction of winding apparatus, by means of the cog wheel or
pinion on which a pin is inserted, with teething formed in a revolving plate or disc, that
will permit the watch to run down at a uniform rate corresponding with the time
indicated by the same.
On winding the watch up the number of clicks or beats on the case, caused by
winding will correspond exactly with the minutes elapsing since the watch was last
wound up. After winding the watch up say at 12 o'clock (midnight), take the watch
and turn the winder thus revolving the revolving plate or disc, the teeth of which work
against a spring fixed to the case, and count the clicks or beats to the amount of 240,
this will denote the time to be 4 o'clock a.m., and so on.
To facilitate counting I prefer the insertion of a lever pin, cam or other projection
on the pinion, to strike a lever and on its being released by continuing the winding,
the lever will cause a tap or stroke to be given on a gong, bell, case or other projection
or object, to mark a certain number.
Thus on a pinion of 12 teeth, one lever pin or cam and consequent tap or stroke
would mark 12 minutes, 5 taps or strokes one hour, and so on.
By another method I fix the spring lever the reverse way and cause it to be released
and the consequent tap or stroke given by the insertion of lever pins in the revolving
plate of 60 teeth, using the pinion then for winding only.
By this arrangement four lever pins would mark 15 minutes at each tap or stroke
on the freeing of the lever, 6 lever pins will give 10 minutes, 12 would give 5 minutes,
3 would give 20 minutes, and so on in proportion.
I prefer to construct the watch either with long or short winders in proportion. In
long winding watches the regulation can the constructed with one click or beat per
minute. In short winders one beat can he arranged to indicate 2, 3, 4, 5, 15, or other
numbers of minutes by adapting the arrangement thus, the calculation giving the exact
time accordingly. In the event of any watch failing to give correct time by this
principle from variation in the strength of spring or other causes, the exact difference
can be found by a few trials and allowed for accordingly.
