Description

Timers, in particular for determining long-distance call times The invention relates to a timepiece, in particular for determining the duration of Long-distance calls, with the release button, for example consisting of a pusher, with the clockwork spring cooperating winding means are assigned. The new lies in the fact that with every movement, be it to start and stop the drive and to return the pointer to the zero position, a partial winding up the clockwork spring takes place.

In the drawing is an embodiment of the than to lie down certain telephone clock trained subject invention shown.

Fig. I shows the watch viewed from above; Fig. 2 is a side view the same; Fig. 3 is also a top view with the glass and dial removed have been, while Fig. q. the clock seen from below with the case cover removed shows.

The watch shown has a case i with a wide rim 2 is provided for placing the clock on the table. As usual, the following are also provided: .a dial 3 with pointer q under glass, mica or the like. and pusher 5 to operate the clockwork.

The housing i is divided into two superimposed compartments by a partition 6. In the larger, lower section, the actual running gear with the barrel 7, the associated intermediate gears and drives, the escape wheel 8, the armature 9 and the balance io are housed (see Fig. Q.). The barrel shaft passes through the wall 6 and carries a ratchet wheel II at its upper end (see Fig: 3). This ratchet wheel works with a spring-loaded pawl 12 and with a pawl 13 which is also under spring action. The latter pawl is via a lever 1q. connected to the slide 15 , which in turn can be moved by the pusher 5. A spring 16 always pushes the slide 15 into its uppermost position. The lower end of this slide is designed as a pawl and is used to advance the pin wheel 17 with five pins: A resilient pawl 18 engages in this wheel, and its pins work together with two levers i9 and 2o: each lever is actuated by a spring 2 i or 22 pressed against the pins of the wheel 17 with their stops r9 'and 2o'. At its end facing away from the wheel 17, the lever 19 carries a whip 23 which passes through a slot 2.4 in the wall 6 and can lie on the edge of the unrest to stop and push the drive. The other lever 2o serves as a hammer for the pointer q, which sits on the sleeve of the pointer q, which is seated on its shaft with severe friction. attached reset heart 25.. The functioning of the clock described is as follows: In the drawing, all parts of the clock are shown in the rest position, ie in the position in which the pointer is at zero.

If the button 5 is now pressed, the lever is on the one hand 14 pivoted and the winding wheel i i by the pawl 13 forward by one tooth switched, on the other hand, the pin wheel 17 is rotated by one tooth. The latter causes the lever i9 with its stop i9 'from the pin below the bar slides and is pivoted by the spring 21 to release the unrest io. Simultaneously the lever 2o comes to rest with its stop 2o 'on a pin and is thus lifted from the reset heart 25. The clockwork starts together with the pointer to run.

The second time you press button 5, the winding wheel will turn i i and the pin wheel 17 shifted forward by one tooth each. Through the first Wheel the clockwork spring is wound up by a certain amount, and the second wheel causes the lever ig to be pivoted by a pin of the wheel, so that the Whip 23 the unrest io and thus the whole drive stops while the stop 2o 'of the lever 2o remains on the corresponding pin. The pointer 4 therefore stops at the place it has reached.

Pressing the button a third time causes the different ones to be returned Parts in the position corresponding to the zero position of the pointer 4. It will in turn first the clockwork spring is wound up by switching the wheel i i. - By the rotation of the wheel 17 by one tooth, the lever i9 remains in its holding position, because his stop is still on the pen. The lever 2o slides with his Stop 2o 'from its pin and is pivoted by the spring 22 in such a way that it falls on the heart 25 and thus brings the pointer 4 into its zero position.

It is therefore noteworthy that every time the lever handle 5 a partial winding up of the clockwork spring takes place. This pulling up thus takes place completely automatically, the elevator device being set up such that each Pressure corresponds to a running time of approximately three minutes. That way will every time the clock is operated, consisting of stopping, resetting and starting, the pen wound up for at least nine minutes. Repeated presses will the spring tense more and more, so that a fairly large power reserve can be achieved can. Over-tightening of the spring can be avoided by any known device will. For example, it would be possible to have the spring with slipping friction in its House to be attached, so that with a certain spring tension, the end of the spring is its point of application changes by leaps and bounds.

The clock described can be used for all types of timepieces and is not limited to use in telephone clocks. For stopwatches for sports purposes, The clock can also be used well for control measurements, etc., with each additional Winding up the work is omitted. Used as a telephone clock, it can be beneficial with Can be combined with a notepad or set up to be attached to the wall be.
