" Clockwork with a balance wheel swinging around a vertical axis "

(Note from M 14 452 / 83a Gnu of March 15, 1954)

The subject of the hiring is a clockwork with a us perpendicular Aohse swinging balance, in which the balance is suspended from the straightening force part and to accommodate laterally attacking elements Forces is stored without vertical support.

There are already watches "known in which the balance on one is fastened vertically between two abutments clamped torsion band or wire. While when running with Torsion band for the balance wheel to absorb forces acting on the side, no bearings at all, just stop rings for the Absorption of transport shocks are provided, the balance wheel attached to the wire is open in the proposal with torsion wire this itself guided above and below the balance with neck bearings. This double-sided clamping of the torsion band or wire, however, in order to achieve a correspondingly low oscillation frequency, either long bands or Wires or relatively heavy centrifugal masses that, however, are about To not exceed the elastic limit of the tensioning wire or tape, reinforced tapes or wires are required A well-known suggestion therefore looks for the balance wheel a one-sided suspension on the Rientkraftteil, whereby bearings are provided for absorbing forces directed transversely to the axis, but which move the balance wheel in the vertical direction not support. A bifilar wound serves as the straightening force part Helical spring, at the lower end of which the balance shaft "is attached iat, which keeps the balance in suspension.

On the other hand, it is proposed, according to the announcement, that the Unxiüi supporting shaft to be hung on one side on a Sorsionsband - as it is known per se with torsion pendulum clocks and - to absorb forces acting on the side - to be guided above and below the balance in neck bearings *

In the figures shows

Pig. 1 is a side view of the gear part of the clockwork.

Fig. 2 is a section through the upper part, which the Shows the suspension of the balance wheel and the regulating device, according to II-II in Fig. 1.

3 shows the balance wheel swinging about a vertical axis with the anchor fork in a view from above according to III-III ;; in Fig. 1.

4 shows a neck bearing according to section IY-IV in FIG. 1.

In Fig. 1, only the drive on a shaft 1 in the Gear wheel 3 mounted on the rear plate 2 is shown. With the latter -! occurs in a known manner, the armature 4 in engagement, on the Shaft 5, the anchor fork 6 is attached, which in turn, how especially also Fig. 3 shows, with the pulse pins 7 of the vertically suspended balance 8 cooperates. At 9 the Bolle is the balance wheel, through the notch 10 of the locking pin 11 the anchor fork 6 is controlled. The balance is on a shaft 12, in turn through the torsion band 13 is hung up and to avoid sideways migration with little play in two neck bearings 14 and 15 is mounted. The neck bearings 14 and 15 are connected in sit the back plate 2-S NEN bearing supports or brackets 16 and 17 attached. The design of such a neck bearing is illustrated in FIG. 4, in which a stone bearing 14 (or 15) mounted in the mount 18 is shown. As FIG. 1 still shows, is a leaf-shaped counter-bearing 19 for the balance shaft is arranged on the lower bearing bracket 17, welohsn dis has the task, possibly

Jerk a'oKttcatch, on which, however, the balance shaft 12 does not sit down during operation. The torsion band is suspended via an angle 20 which is also attached to the back plate 2. At this angle, a bushing 21, on which the sewing pipe 22 with a collar 23 is rotatably seated, is located. Within the threaded tube 22 a rotatable and height-adjustable fastening part 24 is provided, which has a conical interior in which the torsion band 13 can be fixed by means of a wedge pin 25. ⁰ B to determine the set correct height of the torsion strip fastening, a screw 26 is arranged in the collar 23 of the threaded tube 22. Likewise, a locking screw 27 is also provided in the bushing 21 to fix the adjusted balance position relative to the anchor fork 6.

To adjust the period of oscillation of the balance wheel is on the Threaded tube 22 is arranged as an adjusting nut 28 designed as a knurled nut, which has an internally screwed groove a pen 30 ο. Like. One inside the threaded pipe slidable slider 31 engages over. The threaded tube has a longitudinal slot for the pin 30 to pass through on. The slider 31 carries a plate 33 'which one goose tight, just the thickness of the Toraionsbandes 13 corresponding Has slot 34, so that by sliding the piece 31, the effective length of the torsion "band can be changed by adjusting the nut 28.
