A Signalling Device for Clocks.
I, MARINUS ANTONIE SIPMAN of 29 Verlengde Rynkade, Arnhem in the Kingdom
of Holland, Editor and Author 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 a contrivance for indicating the time a clock has to
be wound up or the time of the last winding up thereof having taken place for the
purpose of obviating unintended running off of the clock by reminding the owner or
person in charge, of the required re-winding of the same.
Referring to the accompanying drawing illustrating in the main three modifica-
tions of the improved contrivance.
Fig. 1 illustrates the simplest arrangement consisting in providing a particular
counting disk with hand on the dial plate, said disk carrying the numerals 1 to 31 and

being therefore divided according to the number of days of a month.
up the clock the said pointer can be made to indicate the numeral corresponding
to the date on which the winding up has taken place.
The owner or caretaker being aware of the period the respective clock runs, can at
any time ascertain by the position of the hand, how many days have elapsed since the
last winding, and, after the lapse of the full time, is reminded of the necessity of
re-winding.
Figs. 2 and 3 show a modified arrangement consisting of the work, that is to say,
the spring boxf thereof, which operates by transmission wheels u u¹ the pointer gear
of the clock, being also connected by transmission wheels u² u³ with the shaft a
which carries the hand of the counting dial 21. The proportion of transmission is
so determined, that, when the clock is wound up-which for instance runs with
completely strained spring for a fortnight-the hand z makes a complete revolution
The dial therefor has in this case a

scale of numerals corresponding to the days the mechanism is capable of going at a
time, and the hand actuated by the work indicates how many days are elapsed since
full winding up, thereby reminding of the required re-winding. When the hand has
reached the last numeral (represented as being 14 in Fig. 2) the clock is run off and
has at that time or prior thereto, to be re-wound.
Figs. 4 and 5 illustrate a modification characterized by a particular field indicating
whether the clock is wound or to be wound. fis again the spring box which operates
by transmission gear l² p³ pa shaft 22 on which is mounted a little arm z³, the
ratio of transmission being so chosen, that wheel and consequently also the hand 2³
has completed a revolution prior to the complete running off of the clock. On shaft z²
is loosely mounted an arm which carries a plate or sign with "wind up" or
equivalent indication marked thereon. This sign abuts against pivot or pin 26 as shown
in Fig. 5. The arm or nose 23 moves by the going of the clock in the direction of
arrow 27 and takes along the free arm by means of the pivot 28 provided on the
latter, until this arm is moved beyond the highest point, when arm 2 with sign 26
falls down unimpeded covering the stationary sign 29 provided on the case and
carrying the word "wound" or equivalent indication, its fall being determined and
taken up by pin k. When the clock is being re-wound, the wheel therefore
turning in the inverse direction of arrow 27, the arm or indicator 23 arrives about the
position marked by point g in Fig. 5 and subsequently makes a little over a full
revolution till the running off of the clock. Said point g lies beyond the dead point
of the position of the indicator sign 25 until the latter, carried by its own weight
beyond the dead point, assumes its inoperative position at the pivot 26. As shown in
Fig. 6, this marking of a sign may be represented in a playful way by causing a

figure with the sign "wind up' or equivalent to appear at the proper moment
covering the sign "wound" or such like.
In Fig. 6 a dial with the days of the month is supposed to be provided simul-
taneously with the said covering and uncovering of a sign. On this disk or dial 2¹
moves a hand z which is adapted to be set by hand and indicates the period of the
winding having taken place.
Fig. 7 illustrates another arrangement, in which is provided as in Figs. 1 and 6,
the said month dial z adjustable by hand and also a sign / adapted to be automatically
released for the purpose of automatically marking the time when winding is
required. This arrangement shows the two dials in perfect uniformity below the
hands.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1) A signalling contrivance for clocks consisting of a dial provided on the time
piece or on the case thereof and having numeral marks corresponding to the days of
the month in combination with a hand adapted to be adjusted manually on said dial,
for the purpose of allowing the day of winding to be marked by setting the hand
and thereby obviating the running out of the mechanism, substantially as set
forth.
2) A signalling contrivance for time pieces consisting of a dial provided on the
clock or on the case thereof and bearing the numerals corresponding to the days of
the month, in combination with a hand adapted to be set by the spring box and
coupled therewith, for the purpose of allowing the running out of the mechanism to
be ascertained by the position of the hands, substantially as set forth.

3) A signalling device for time pieces consisting of a covered or coverable sign
provided with "wind up or equivalent indication and adapted to be automatically
uncovered by the spring box prior to the running out of the time keeper, substantially
as set forth.
4) The application, in lieu of the sign with indication to wind forming the subject
of claim 3, of another marking device adapted to be operated by the spring box of the
time piece so as to become visible to the beholder as an indication for required
winding, substantially as set forth.
5) The combination of the signalling contrivance characterized in claims 1 to 4
substantially as indicated and described.
