Uhraufzug- und Stellvorrichtung.Clock winding and adjusting device.

Patentiert im Deutschen Reiche vom 5. Oktober 1911 ab.Patented in the German Empire on October 5, 1911.

Die Erfindung betrifft Uhraufzug- und Stellvorrichtungen, bei welchen die Ein- und Auswärtsbewegung der Spindel die Einschaltung der Aufzug- und der Stellvorrichtung mittels unmittelbar auf dem Aufzugrade sitzender Kupplungen bewirkt.The invention relates to clock winding and adjusting devices in which the inward and outward movement the spindle, the activation of the elevator and the adjusting device by means of seated directly on the elevator wheel Couplings causes.

Gemäß der Erfindung sind die Außenflächen der beiden Kupplungen von den Armen einer in. der Mitte gebogenen und festgeklemmten ίο Doppelfeder belastet, wobei der eine Arm durch einen Schieber zurückgedrückt werden kann. Durch diese Zurückdrückbarkeit des Armes wird nach Herausnehmen des Uhrwerkes aus dem Gehäuse die Handhabung des ersteren erleichtert und das Aufziehen und Stellen desselben ermöglicht.According to the invention, the outer surfaces of the two couplings of the arms are one in. the middle bent and clamped ίο double spring loaded, with one arm can be pushed back by a slide. Due to this push-back ability of the Armes, after removing the movement from the case, the handling of the former is facilitated and the winding and Make the same possible.

In der Spindelbüchse 2 ist die vierkantige Aufzugspindel 3 geführt. Das Stundenrad 4 und das Viertelrad 5 sind in der unteren Platte B angeordnet.The square winding spindle 3 is guided in the spindle sleeve 2. The hour wheel 4 and the quarter wheel 5 are arranged in the lower plate B.

In die Zahnräder 4 und 5 greift das Wechselrad 6 ein, das auf einem von der Platte B gebildeten Stift 7 angeordnet ist und durch eine Scheibe 8, die an der Platte befestigt ist, in seiner Lage gesichert wird. An einer Seite trägt das Rad 6 Kronenzähne 9, die durch eine Aussparung 10 in der Platte B frei durchtreten können. In diese Kronenzähne 9 greift das Zeigerstellrad 11 der Stell- und Aufziehvorrichtung ein.In the gears 4 and 5, the change wheel 6 engages, which is arranged on a pin 7 formed by the plate B and is secured in its position by a washer 8 which is fastened to the plate. On one side the wheel has 6 crown teeth 9 which can freely pass through a recess 10 in the plate B. The pointer setting wheel 11 of the setting and winding device engages in these crown teeth 9.

Der Aufzugvierkant 12 ist so angeordnet, daß ein Ende in der Büchse 2 liegt und sein abgerundeter Stift 13 durch die Büchse des Stellrades 11 hindurchreicht, die mit einer verhältnismäßig langen Aussparung 14 von quadratischem Querschnitt zur Aufnahme des Aufzug Vierkantes versehen ist. Weiterhin ist auf dem Vierkant 12 verschiebbar und mit ihm drehbar ein gezahnter Kupplungsteil 15 angeordnet, und zwar unmittelbar neben der Büchse 2 und in der Kammer 16, die von den Platten A und B gebildet wird, beweglich.The elevator square 12 is arranged so that one end lies in the sleeve 2 and its rounded pin 13 extends through the sleeve of the adjusting wheel 11, which is provided with a relatively long recess 14 of square cross-section for receiving the elevator square. Furthermore, a toothed coupling part 15 is arranged on the square 12 so as to be displaceable and rotatable with it, namely immediately next to the sleeve 2 and in the chamber 16, which is formed by the plates A and B , movable.

Der Kupplungsteil 15 ist mit einer langen Nabe 17 versehen, welche gegen das Ende der Nabe des Stellrades stößt. Die Stellung des Kupplungsteiles und des Stellrades werden durch eine Doppelfeder 18 bestimmt. Die Feder 18 ist in einer Aussparung 19 der Platte B angeordnet und mit den beiden Armen 20, 21 versehen. Der Arm 20 ist stärker oder weniger elastisch als der Arm 21 und wirkt gegen das innere Ende 13 des Aufzugvierkantes 12 oder der Nabe des Rades 11. Der kürzere Arm 21 liegt gegen das hintere Ende des Kupplungsteiles 15 derart, daß das Zahnrad 11 und der Kupplungsteil 15 sich gewöhnlich mit ihren Naben berühren.The coupling part 15 is provided with a long hub 17 which abuts against the end of the hub of the adjusting wheel. The position of the coupling part and the setting wheel are determined by a double spring 18. The spring 18 is arranged in a recess 19 in the plate B and is provided with the two arms 20, 21. The arm 20 is more or less elastic than the arm 21 and acts against the inner end 13 of the elevator square 12 or the hub of the wheel 11. The shorter arm 21 lies against the rear end of the coupling part 15 such that the gear 11 and the coupling part 15 usually touch with their hubs.

Claims

The operation of the device is as follows:

A pressure on the winding spindle 3 moves the winding square 12 until the adjusting wheel 11 rests against the shoulder formed by the spindle 13. The setting wheel is thereby disengaged from the crown teeth 9 of the minute wheel 6. In this position, the setting wheel rests against its bearing ii ' ⁷ and n * of the plates A and B , while the spring arm 20 is pushed back and the spring arm 21 rests on the coupling part 15 the square 12 moves until its teeth engage in the radial teeth 22 on the back of a winding wheel 23.

This elevator wheel is immovably and rotatably mounted in long central bearings 23 ″ and 23 * of plates A and B and is constantly in engagement with a gear wheel 24 which carries or is attached to an elevator wheel 25. With the latter, the customary, Main spring, not shown here, wound up.

When, in the position of the parts shown in FIG. 2, the winding spindle 3 is rotated is, the resiliently held with the teeth 22 in engagement coupling part 15 rotates the Winding wheel 25, while, despite the fact that the adjusting wheel 11 is also rotated, the wheel 6 is at rest remain.

To set the clock, the winding spindle 3 is pulled out so that the strong Spring arm 20 brings the wheel 11 into engagement with the gear wheel 9 and the coupling part 15 out of engagement with the teeth 22 of the winding wheel 23. Moves as the spindle rotates the wheel 11 the change wheel and this in turn the hour wheel 4 and the minute wheel 5. The device accordingly represents a directly acting, a coherent whole, self-acting elevator and adjusting device with self-locking adjusting wheel that resiliently releases the teeth of the wheel 6 before the pressure is so great that the teeth are broken off if the spindle 3 is turned too much.

In order to facilitate the assembly, repair and cleaning of the device, a slide 26 is let into the plate B in such a way that it lifts the spring arm 21 from the coupling part 15 by moving it in the direction of the arrow α (FIG. 3). As a result, the spring arm 20 moves the wheel 11, and the winding wheel with its gear can be lifted from the bearing 23 *, while the spring 18 remains in the recess 19 of the lower plate B. By means of the slide 26, the watchmaker can also set the clock outside the capsule by moving the slide in the direction of arrow b . As a result, the spring arm 20 is lifted from the hub of the wheel 11. As a result, the coupling part 15 is displaced by the spring arm 21 and brought into engagement with the gear 23, while the wheel 11 is pushed out by the coupling hub 17 and disengaged from the gear 6, so that the watch can run as in its capsule.

In order to be able to easily remove the spring from the plate, a small recess 27 is advantageously made in the plate B , into which a small steel or rod can be inserted under the spring 18.

Ρλϊεν τ-claim:

Clock winding and adjusting device, in which the inward and outward movement the pulling shaft, the activation of the elevator and the adjusting device by means of directly causes clutches seated on the winding wheel, characterized in that the outer surfaces of the two Couplings from the arms of a double spring bent in the middle and clamped (20, 21) are loaded, the arm (21) of which by a slide (26) if desired can be pushed back in order to handle the former after removing the movement from the case to facilitate and to enable it to be pulled up and placed.
