Pocket or wrist watch with a stopwatch facility

The innovation "refers to a pocket or wrist watch with stopwatch facility.

Stopwatches that measure a period of time, It is also known to assemble such stopwatches with pocket or wristwatches in the known stopwatches the pointer begins to run when its drive is coupled to the clockwork and stops when it is uncoupled will.

The pocket or wristwatch of the innovation is characterized by the fact that the pointer of the stopwatch device rotates synchronously with the minute hand and for using the

660481

Stopping device rotated arbitrarily to a zero position and held there until the start of the period to be measured will,

The drive of the pointer of the stopwatch is offset at an angle opposite the power take-off point for the clockwork, taken from the ring gear of the barrel that also drives the movement.

The pointer of the stopwatch device is expediently by a circumferential underneath the dial and through a window in the dial is shown observable dial.

According to the invention, there is a slip clutch in the power path of the barrel dial.

This is expediently realized by a friction tube that can be rotated with friction on the shaft of a gearwheel, which combs with barrel sprocket.

With the friction tube as a shaft bearing, an intermediate gear attached to it can then be used to drive the dial

and a Valöoux heart curve around the gear shaft or with it turn.

The Valjoux heart curve is known from the end of a two-armed lever in each position is always reset to the same position, which means that in the present case. Fall the dial is brought to the zero position.

The drawing shows, for example, schematically and partially on average, a preferred example of the innovation namely is:

Fig. 1: a section through a clock mechanism with a stopwatch device the innovation, and

Fig. 2: a plan view of the device for actuating the heart disk.

The frame 10 includes the usual watch movement parts, such as the barrel 2, the Eadbrücke 3, the second drive 4, the Mijiutenradbrücke 5, the minute drive 6, the hour wheel tube 7 and the minute tube 9 is the dial with the window 11. The dial 12 can be seen and read through the window. The dial carries a pointer 13 (Fig. 2). The dial 12 is

attached to the wheel 14 ″. This is freely rotatable about the hour wheel tube 7 ″ and is supported against the hour wheel 7a with a ring 15 in front of it. _{The intermediate gear 17 5,} which is fastened to the friction tube 18, meshes with the outer ring gear 16 of the wheel 14. The friction tube 18 is rotatable with friction on the shaft 19 of the gear wheel 20 and thereby forms a slip clutch. The gear wheel 20 engages in the ring gear 21 of the barrel 2.

The Valjoux heart curve is also on the friction tube 19 22 attached. The correspondingly designed end 23 of the two-armed lever 24, the is rotatable about the pin 25. The pusher pin protruding radially out of the watch case acts on the free end 26 of the lever 24 27. The dial 12 therefore usually rotates synchronously with the minute hand. Should the stop device be actuated the heart curve 22 is activated by the pusher 27 turned over the lever 24 so far that the end 23 of the lever 24, as shown in dashed lines in FIG. 2, lies against the flattening of the heart curve. Here the friction of the friction tube 18 overcome on the shaft 19 and the dial 12 stopped via the intermediate wheel 14 and brought into the zero position.

In this position it remains in place if the clutch is slipping between 18 and 19 as long as the pusher 27 "is pressed. If the pusher 27 is released * the dial runs 12 again synchronized with the minute hand.
