Specification Accepted, 7th Sept., 1888
We, HENRI TURLER and CÉSAR TURLER of the firm of Turler frères of 13 Industrie
Strasse, Bienne, in the Republic of Switzerland, Manufacturers, 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 universal chronograph having for its principal
purpose to allow any space of time elapsed up to a given moment to be distinctly
ascertained or measured in hours, minutes and seconds, the apparatus being at the
same time much simpler and cheaper in construction than the chronographs heretofore
employed, by means of which the period elapsed from any point of time up to a
certain moment can only be ascertained by minutes and seconds.
Referring to the accompanying drawing, Fig. 1 is the front view of the improved
chronograph when in action, the dial being removed.
Fig. 2 the same view at the moment its action is to commence and the hands point
to zero.
Fig. 3 the front view of the watch when closed.
Fig. 4 a vertical section along line A B Fig. 2.
The dial a Fig. 3 has in addition to the two ordinary hands for hours and minutes
three small dials bc and d, each of which has a hand rigidly connected with the
tubes c and d respectively, showing the seconds e the minutes and d the hours.
These hands are destined exclusively for the chronograph proper which is only set in
action when the period elapsed from any suitable time up to a certain moment is to
be ascertained. The movement of the improved watch that is to say the wheel work
and escapement is the same as in any ordinary watch with lever motion and is arranged
In the watch case in the usual manner.
The minute tube carries a wheel e with 48 teeth gearing into the wheel with an
equal number of teeth and having therefore the same travel. A small disc c with
heart is loose on the wheel on which is screwed an elastic open ring g taking
long the disc c¹¹.
The wheel revolves about the same pivot with the tube
carrying the hand for the minute dial c.
is the change-wheel gearing into the

page_text: count wheel i. On the latter is situated the wheel & with 32 teeth geared with the
wheel m having 64 teeth and making one revolution within 24 hours. On the wheel m
are arranged in the same manner and for the same purpose as on the wheel f, the
spring n, the disc d" with heart and the tube d on which the hand for the hour
dial d is situated. On the second-pivot is provided a disc o on which are likewise
arranged, as on the wheels fand m, the spring p, the loose disc with beart b¹¹¹ and
the tube for the hand of the second-dial b.
.11
A three-armed lever 7 pivoted at is connected through the sliding pin t with the
pins projecting outwardly from the watch case and is so arranged that on pressing
on the pins the three arms q, q, q, come simultaneously in contact with the
hearts and as shown in Fig. 2, slide along the outer edge of the same and
bring them with the tubes c and d into the position shown in Fig. 2, the three
hands of the chronograph on the dials band & springing on zero (Fig. 3) without
disturbing in any way the movement of the watch. Subsequently the chronograph
is immediately actuated the spring holding the lever in tension.
"
The improved or universal chronograph can be advantageously used in sporting,
travelling, cabdriving, and for numerous other purposes, where precision in time is of
importance.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
In watches:
The application of a chronograph for hours, minutes and seconds, essentially con-
sisting of wheels fand m connected with the minute-tube, that is to say with the
count wheel, and the disc o secured on the second-pivot on which parts are situated
respectively the springs g np, the discs c¹¹d with the hearts, and the tubes with
the corresponding hands, in combination with the three-arined lever revolvable
about v and actuated from s, substantially as and for the purpose set forth.
