"Small electric watch"

this application becomes the priority of the corresponding French application Io. 772,222 of 8 ^A ugust 1958 taken claim i.

The innovation "essentially concerns a small electric watch in particular from the type of wristwatches o.

For a long time, efforts have been made to manufacture small watches, who plug in an electrical power source in their G-ehouses, which gives the entire clockwork permanent autonomy. So far, all attempts in this regard have been unsuccessful, either because it has been impossible to obtain elements or current collectors of very small dimensions, or the entire work in a housing of acceptable and useful ones To accommodate dimensions or a sufficient precision to achieve this work. .

It's already an electric clock with a fixed one

Fitting, which consists of two Schen-IeLn provided with coil lugs is composed, one of which is arranged at an angle to the other, so that they result in an IT-Porm, became known.

Both the circuit of the coil signals and the constructive one However, through formation of the armature are not suitable for use on small clocks that run continuously and in large Series can be produced simply and easily. At this The well-known watch, in particular, is the balance anchor due to its non-concentric I-shape only in complicated machining-s processes to produce and the desired mass production let not reach each other. . : ■ "

Another part of the known carrion guides is that the movable armature, starting from the moment when it faces a fixed pole, up to the position in which, in turn, lies opposite the other IPest pole of the status, can only execute a very small angle. - ^ ies. has the consequence that torsional vibrations of small amplitudes can occur, which affect the accuracy and that furthermore, each pole of the movable armature can sweep past several poles of the fixed fittings, which in turn makes the chronometric ' The behavior of the watch would be significantly impaired. In this context, it should be borne in mind that even with the best magnetically permeable materials' in one not fed magnetic circuit, there is always a residual magnetism, which creates an attraction on the moving armature. exerts force, which lowers the accuracy as far as possible. The known clocks constructed in this way or the proposals

_ ¹ Z _

. J

for the production of the same, therefore have not yet had any gained practical meanings. Also an electric clock that continues to become known, which is used in motor vehicles is intended, does not correspond in its structure to the requirements that are to be placed on., - a watch. At this The clock that has become known is the fixed armature τοη three Formed ropes which are connected to each other so that the Form of a V is created. With regard to the circuit of the coils, the shape of the coil armature and the vibration amplitudes of the. Balance anchor, what has just been said applies in full. It is also an electric clock with a single source of energy has become known which feeds a coil carried between two arms of the balance so that the coil itself is in that of two permeable magnets generated suffering from torsional vibrations This type of coil arrangement has the disadvantage that it does The weight of the restlessness increased considerably.

The described below £ innovation, the disadvantages are avoided altogether and created a watch that with regard to the smallness of the dimensions and the absolutely necessary accuracy all. Meets requirements,

The object of the innovation is an electric watch with a drive mechanism consisting of one of a power source supplied electromagnet circuit and a spiral spring; there is unrest in the field generated by the circuit is located and the opening and closing of the supply circuit controls.

According to the control, this watch has the following features in combination on:

a) an electromagnet circuit, which is formed by two coil windings that are connected in parallel and by two - ^ elements or accumulators are supplied, whereby the coil windings are attached to the legs of a fixed armature of the ^ orm of a T whose axis of symmetry coincides with the or one of the axes of the: housing and furthermore with said legs at their ends adjustable pole pieces are equipped;

b) one consisting of a permeable metal, a unrest forming anchor, the one between the pole pieces just mentioned Rotatingly oscillating arranged and the action of a return spring is subordinated, the said anchor with a contact element, which serves to open and close the "supply circuit of the coil oscillations, as well as with a Amp ^ litudenbegrenzungseinrichtung is equipped

te) a device for counting the oscillations of the unrest, consisting of a steering wheel, which is actuated by a pen who listens to the restlessness and transfers the movements to a clockwork gear,

d) a device for setting the hands, consisting of axes for blocking the balance and the steering wheel, as well as means for engaging the clockwork drive wheel with the pointer setting wheel,

e) a housing, which is intended to hold the drive mechanism

nism and the clockwork transmission and a receiving space for the supply elements, the latter on both sides The above-mentioned V-shaped fitting can be stored in the height of the üusammentreffpunktes of the two armature legs are.

According to another characteristic of the rise in prices, a magnet connects in particular a permanent magnet, the two pole shoes together and serves as a polarization magnet.

Another characteristic of wages is the development of the Hpu designed in such a way that the flux induced by the permanent magnet opposes the flux induced by the two coils is..

According to a further feature of the fire, the engine has a pointer setting device with means for locking the balance and the drive or ratchet wheel and means for engaging the minute wheel with the hand setting wheel.

This pointer setting device has a, for example, slidably mounted, externally operable pin with a Sehrägflache that forms a crouch and a lever linkage operated to lock the unrest.

The crouch of the pointer setting pin is in contact with a / lever, which pushes back a second lever overcoming the force of said return spring, this second lever Leverage, for example, on an inclined or run-up track

one or two further levers or fingers slide, which causes depression of the "engagement $. with agitation, while a .of with the axis of said second lever firmly connected to linger engages the drive wheel between two teeth and the latter shuts down.

The movement of the clock according to the invention also has a deflection limiter with a swinging bail, which is provided with a gable piece that freely engages over a linger or pin sitting on the balance, and magnetic pins are arranged on both sides of the bolt in such a way that the Seal, if it is not carried away by the unrest, ji rests against one of the magnetized pins or is attracted by this.

For a more convenient understanding of the following description are intended first the general principle of assembly and then the individual mechanisms that make up the entire clockwork, be treated.

General principle

In the selected embodiment illustrated in the drawing is the clock according to the invention according to the Q-principle the use of a gear regulator, which consists of a ral unrest with electromagnetic operation exists. Elements or current collectors enclosed in the watch case immediately supply the energy required to maintain the oscillations the unrest, which as a result simultaneously fulfills the task of a drive and a G-controller.

Fig. 1 shows very schematically the structure of the clock according to the

Renewal. In this visual image there is an electrical element 1 provided, the positive pole of which via a conductor 2 with a contact 3 is connected, the other terminal 4 to the Mass 5 is applied. The negative pole of the element, or Current collector is via a conductor 6 to a at 7 schematically indicated winding connected, the opposite terminal 8 is also applied to the mouse.

A rectifier or a rectifier is expediently connected to the winding 7 Enclosed diode 9, which has the task of appreciating the contact.

As shown in FIG. 2, the entire drive is in practice provided with two coils 7 and 7 ', the cores 10 and 10 ^l; expire in PoI shoes 11 and 11 '. :

In the case of FIG. 2, two elements 1, 1 ^! used, which are in parallel with each other and feed the turns 7 and 7 'of the two coils via conductors 12 and 12' .. The ends and 13 'of these turns are connected to the ground, as can be seen at 14, 14'. The opposite poles of the elements are connected by conductors 15, 15 ', which lead to contact 4.

The two pole shoes 11 and 11 'are also through one another a permanent magnet 16 connected, the task of which is shown in Figs. until τ oter

and d illuminates. Are at their opposite end

the core 10, 10 * connected by a part 17 made of magnetic metal.

Between the stator shoes 11 and 11 'there is a

- 10 -

the armature 18 is arranged with two pole pieces or pole horns 19 and 19 '.

Further, this anchor is equipped with a (in Fig. 2, 2 ^{1 S,} 2 ^He not shown) connected to the coil spring and thus forms

this way the regulator of the clock.

The vibrations of the unrest are counted> τοη a wheel, that basically advances by one tooth with every oscillation and its rotary motion is transmitted to the pointer via a gear train.

This general structure is further enhanced by a special hand adjustment device and to be supplemented by a deflection limiter, which allows to avoid untimely vibrations of the restlessness.

It should be noted that the two coils forming the stator 7, 7 * are electrically connected in parallel with one another. The coils are wound in such a way that that of each one Winding of the two coils, see magnetic flux complement each other when the current flows through these windings that the contact 4 lets through. These magnetic Fluxes are the magnetic flux induced by magnet 16 opposite.

The coils and the magnet are arranged so that the in the coil induced magnetic flux is essentially twice as strong as the magnet induced flux. ^ ie stator cores are dimensioned so that they are close to the saturation limit

ze "if they are from the induced by the magnet magnetic! flux are flowed through.

Like the jig. 2 ^bls can be seen, a flux 1 flows through the magnetic circuit when the contact 4 is open.

This I ¹ IuB is closed to the stator cores and a very weak leakage flux then flows over into the movable armature, the air gap of which has a fairly strong magnetic resistance. As soon as the contact 4 is closed (Fig. 2 * ^eT ), a current flows through the coils 7 and 7 * and the stator cores are then ^{passed through by an I 1} IuB, which has the same value as φ , but in the opposite direction. At this moment the fluxes / £) and φ are closed by the movable armature despite the magnetic resistance of the air gap. The anchor or the unrest 18 is then traversed by a river which is equal to a fraction of the sum of the flows ^ U / and φ , and in this way receives a fairly strong impulse.

While the magnetic circuit of the cores 10 and 10 ^r - by: p ^ saturated flux, one can still through the anchor bewegliehen hindurchsehieken a larger flow than m. The polarizing magnet 16 thus allows a magnetic circuit to be used to a lesser extent, which means a saving in terms of both costs and space requirements.

Contact device ■

- 12 -

Contact device ^:

Based on the in ^ ig. 2 shown example should mm a Execution of a contact are described, -der the Electric power supply of the Spuien guaranteed.

Like the I ¹ Ig. 2, 3 and 4 illustrate, the positive poles of the electrical elements are connected by the .conductors 15, 15 ″ to a part 20, which is hereinafter referred to as the contact. This part 20 is firmly connected to an Ana.21 and the whole is mounted on an axle 22 with more or less gentle friction. The contactor 20 plays the role of the first contact elements .. It is expediently movable about its axis 22 and, through its rotation, allows the deflection range of the armature's oscillations to be viewed. & © 3iiten.

An elastic lamella 25 acts with the contact fan 20, Wire spring or the like together, one of the ends of which is attached to an appropriately orientable contact or covering 24 * This contact terminal 24 is connected to ground 5. The leather link 23 is flexible and its free end is arranged such that it comes into contact with a part 25. This part 25 belongs to a plate or dock 26, which is on the axis of the anchor or the tinruhe 18 is attached (their spiral can be seen at 60).

The installation of the various parts is carried out in such a way that the Contact wire 23 remains oriented in such a way that it

- 13 -

position does not touch the contact fan. In other words: In the rest position, the contact is interrupted and no current flows through the coils.

All components of the contact device are expedient attached to an easily removable plate.

^ he mode of operation of the contacts is as follows: When the unrest in the sense of T- (- ^ ig. 2) swings out, there is a point in time at which the contact cam 26 takes the free end of the wire 23 _w with it, this then with the edge of the Contact fan 20 comes into contact. This position is particularly in the S ¹ Ig. 3 to see. The electrical circuit between the electrical element and the coils is then closed, the unrest 18 continues its rotary motion and the curl 26 escapes from the wire 23 and opens the contact.

The contact cam is with respect to the poles 19 and 1§ 'with such an angle of attack that the beginning of the contact occurs at a point in time in which the Pole horns have moved very close to the stators, but before they are opposite the latter. At this moment exert the stators on the pole horns an electromagnetic attraction force, which is essentially tangential is directed towards the anchor, causing the latter a G-ang impulse receives.

When the armature returns (rotation in the opposite direction to I \, B ¹ Ig .. 2) the bracket comes into contact with the wire 23, but falls away from it without closing the contact .. At

every respect mud Herschwingung the ^A nkers there is thus only a single pulse. -

Since the pulse or current surge occurs only once for a full period, it is possible to set the isoehrnism in this way to regulate that the! »age of the impulse in relation to the Adjusts the center of the spiral exactly.

To display the hours, the oscillations carried out by the armature must be counted, this is done by means of a Gear 28 of a special profile, hereinafter referred to as the drive or climbing gear.

From Figures 3, 5, β and 7 it can be seen that the armature 18 carries a pin 29 or the like, which is used for driving or port switching of the climbing wheel 28. The teeth of the climbing wheel 28 have a special profile insofar as their ends are beveled in such a way that the drive by the pin takes place easily in a certain sense and these teeth slip out of the pin as soon as the port switching is completed. The Pig. 5 and 7 show two teeth D-, and Dg. The - ^ nd a. and b of these teeth describe a path X, while the end of the drive pin ;. 29 des: Anchor a path Έ Describes. These two paths intersect at points A and B, and it can be seen that at point B the pin leaves _{the drive of tooth D 1.}

So that the drive wheel always assumes a precisely defined position, is on a plate JO on which the axis 31 of the drive

- 15 -

Axis 28 is fastened, a magnetic pin 32 or the like. Provided that attracts the tooth that is in the next liehne of the same. So after the tooth D, from the drive, pin or pin to the position D indicated by dashed lines in Fig. 5 ^! In this way, the wheel is attracted by the magnet 32 in the direction of the arrow F and this movement is continued until it reaches the position D _? achieved. So it will always be a precisely determined position.

When swinging back, the anchor turns in the opposite one Sense of the continuation movement (Fig. 7); since the drive pin has left tooth Dp and is in contact with one other tooth D, it forces the steering wheel to step back so far that until this tooth D "is indicated in the dashed line Position D 'is reached, whereupon it leaves the tooth. As a result of the force of attraction exerted by the magnet 12, the climbing wheel is below returns to end-to-end conditions and takes again the Starting position, which corresponds to position D- in FIG. The movement of the climbing wheel BX 28 is transferred to the hands via a gear train that has an arbitrary minute counter at the end. In contrast to a clock with - spring drive transmits this gear train in the present case only has a very weak torque »

Pointer setting device

An example of a pointer setting device is illustrated in FIGS. 4, 8, 9 and 10. This pointer setting device exists essentially from a rod B3> for example between

- TS -

; ■ ■ ~ 16 -. ■

is slidably mounted in two positions. These two
Positions are shown in Figs. 8 and 9 and correspond to two notches 34 and 35 in which a wire spring
36 snaps into place. On this rod is a wheel, the pointer setting wheel 37> fastened and works with a wheel 38 of the;
Pointer / ^ works together.

Over the two hats 24 and 35 of the rod 33 this is with
a more or less conical inclined surface 39, for example, which cooperates with the end 40 of a lever 41 which can be tilted about an axis 42. The Ende43 this lever cooperates other, swinging around a üchse 4 €] £ lever 45 with the arm 44th This second lever has an arm 47 'which can interact with an inclined surface 48. ^ Ie inclined surface 48 is provided, for example, on an elastically deformable member 49, the hook-shaped end 50 of which can rest against the rim of the armature of the unrest or at any other point thereof.

The elastic lamella 49 is at 51 for example on the
Wheel bridge attached by a screw and two wedges for adjusting the position.

An angled part 52 is attached to the axle 46 and can slide between the teeth of the drive or climbing gear 28. In the upper part of the wheels there is a resilient lamella 53> which is attached at a point 54
and a ®näe 55, which with the arm 44 of the lever 45
is in contact.

- 17 -

-M-

The operation of this device is very simple. In the rest position (- ^ ig. 9) the spring 36 is indented in the lut 35 and the spring 53 pushes the two arms 43 44 of the. Lever 41 and 45 back. To set the “clock hands, first pull the rod 33 in the direction of the arrow ^ _7. ” During this movement, the arm 40 of the lever 41 slides on the conical shoulder 39 of the control rod 33 and tilts in the direction of the arrow i ¹ . the end. Slein inde 43 takes the end 44 of the lever 45 with it, overcoming the force of the spring 53. This rotary movement causes the end 47 of the lever 45 to cling up on the inclined surface 48 and forces the elastic rope 50 to tilt in the direction of arrow IV, thereby blocking the unrest or the anchor. At the same time, the rotation of the lever 45 causes a corresponding rotation of the part 52, which is aufkeitl on the axis 46 and locks the drive or steering wheel 28 by engaging it between any two teeth.

This sliding movement of the rod 33 simultaneously causes the pointer setting wheel 37 to engage with the wheel 38 of the pointer mechanism the clock.

To avoid the unrest in a position, in which the contact is closed, there are notches on the balance 56, for example two Auskerfenggen provided. if so the rope 50 engages in one or the other notch, as a result, the anchor or the unrest can still have one perform some movement to allow it to snap out in the closed contact position.

Magnetic circle

As can be seen, the magnetic circuit contains two suitably long coils Ί \ 7 'with a core made of a metal that is very permeable ^{to the magnetic I 1 IuJS.} These coils are arranged in a triangle, as can be seen, for example, in FIGS. 4, 10 and 11, whereby it is possible to distribute the gear train with a very small space requirement.

The pole shoes 11, 11 'are arranged at the ends of the Ύ formed by the two coils and the armature 18, which consists of a ring for the magnetic S ¹ IuB. This anchor consists of a ring 57 made of very permeable metal and is firmly connected to a web or disc 58 which is attached to a yoke 27. The structure of this anchor is in its details from I ¹ Ig. 16 can be seen where compensation holes 110 are shown by name.

The two pole horns or pole shoes 19 and 19 'are diametrically opposite opposite points of the Sik'eä & ss provided and work together with the pole pieces of the stator. These two poles are expediently arranged at two different heights, to avoid the braking effect, which would otherwise be disadvantageous and would appear if, the one pole horn of the armature passes the opposite pole of the stator. This arrangement Also allows each of the two air gaps to be independent to adapt from each other, as the possible deviation of the runner of concentricity then by regulating the Air gap can be corrected.

The Aeh8e of the anchor is put on the sock 26 (Pig. 17), who on the one hand carries the rope 25, which is normally on the Contact wire 23 acts, and at the same time a pin 59, which is used to drive the climbing wheel 28.

Fig. 13 shows the schematic of the structure of the magnetic circuit, in which the components already described can be found with the same reference numbers.

In order to avoid the destruction of the contact during the separation, a rectifier 9 is used, for example from a there is a © iode connected to the winding 7. This Rectifier allows when the contact is torn off that see the energy stored by the choke of the coils as triggers reverse electrical voltage and that in this way the formation of a tear-off spark is avoided. It's closed notice that this energy is partially recovered, since the current flowing through the diode is returned to the coils. reverses and generates an additional electromagnetic pulse that is sent to the armature.

Electric circuit

The coils are expediently made of insulated copper wire. Of the The start of the winding is, for example, by dissolving it to the ground of the core, while the exit of the winding is formed by a conductive varnish that is applied to the last turns this winding has electrical contact. The connection between the coils is done on the one hand by the electrical Contact made by screwing the cores onto the

- 20 -

Mass of the clock plate is achieved, and on the other hand by pressing the upper connection on_.the conductive paint, from which is mentioned above.

The electrical connections between the individual components are made by the upper connection 12, 12 * and the lower connection 15, 15 '. These connections exist for example from metal strips, which are shown in FIGS. 10, 11, 12 and 4 can be seen. The connections are held in place by screws that are supported on isolated warts and, which are screwed onto the various components whose electrical connection they establish. ^

The electrical elements sslbst are two-way in blocks

61 (Fig. 15) e.g. B. made of plastic, those with smiles

62 for fastening and with a fixed connection 63 and an elastic connection 64 are provided. A poli-insulating material 65 is placed between the two connections. This _{:. ;} Small block 61 made of plastic or the like is therefore inserted into the watch case and connected to conductors 12 and 15.

Handwork

The second hand is particularly shown in FIG. 18, while the other hands can be seen in FIGS. 19 and 12.

If the hour hand and minute hand have no special feature, this is not the case with the second hand. This is in two ways characterized by a counterweight that has the shape of a "lightning bolt", as in 66 in I ¹ Ig. 18th

- 21 -

you can see. It should be noted that this discharge is necessary, as it is in the G-egensatζ to a classic watch the gear train is free according to the innovation and only braked will. If the second hand is not relieved, it runs the risk of turning under the action of a shock and can cause the time to be incorrectly displayed on the dial by taking along the wheel train.

It can be mentioned that "lightning shape" with the to the center directed tip and the wide outer part the best conditions for relief or balance and still gives the pointer a pleasing appearance.

Vibration limiter

Since it is mainly a wristwatch that the user wears on his arm, certain movements of the same can of course give the restlessness or the armature such an acceleration that the oscillation deflection is more than 360 °. A contact is then established which gives the armature a new current surge or impulse, which tends to increase the range of deflection. In order to avoid this phenomenon, a bolt is used, the position of which is determined magnetically and which acts as a vibration limiter - it is the deflection or visual vibration limiter in the I ¹ Ig. 3 shown in detail and also in the ^ ig. 11 visible. -. .

This visual oscillation limiter essentially consists of one

- 22 -

Latch 67, which is seated on an axis 68. The axis 68 ^! is fixed in a board 69 and in another board IgX & M, not shown. The bolt 67 ends in a fork 70, in which a pin 71 belonging to the armature 18 engages. Magnetic pins 72 and 73, which are fastened to a permanent magnet 74, for example, are arranged on both sides of the fork 70.

As is readily apparent, the fork is moved into one of the end positions by magnetic attraction, i. H. in Touching one or the other of the two pins 72, 73 withdrawn. An untimely movement of the armature 18 is thus by the contact of the pin 71 and the two legs the fork 70 held in check. The fork takes stents a precisely determined position in contact with one or the other of the two pins, if the anchor one performs normal movement.

The case

The watch case can be designed in the most varied of ways. His Baurat depends largely on the ^z ahl SK of used electrical elements and their arrangement. You can use one or more elements at the same time. However, it is also free to provide a space for one or more reserve elements, which the user can switch on himself when he notices that the element or elements in operation are exhausted. So z. B. two rooms are available, one of which is used to accommodate the element in operation and the other to accommodate the reserve element.

- 23 -

In the illustrated embodiment, the watch case is specially designed to accommodate several elements. The elements can of course be accommodated either together or separately, as for example in. 4 is shown. In any case, the most convenient place for accommodating the elements is the space that lies between the two connections 75, 75 'and 76, 76 "on either side of the two coils 7, 7". The accommodation, the EHemente can take place in the sighting and between the two legs, which are used to attach the housing: - on the strap.

In particular, it can be stated that the work is appropriate is installed through the opening left free for inserting the glass pane. The watch glass is then fitted into its housing and ensures the sealing and fixing of the Clockwork. There is expediently enough space between the outer edge of the dial 77 (FIGS. 19, 22) and the watch glass frame left free to allow the screws to be inserted and secured with the necessary contact pressure to be achieved a good electrical contact between the connections of the movement. This arrangement has the advantage that the electrical elements can be inserted through the case back without it being necessary to uncover the movement. ; It is therefore possible to easily change the electrical elements, without running the risk of damaging the work or admitting dust. It can also be seen from Fig. 20 how the electrical elements inserted through the housing base will. You can see a schematically shown one here

electrical. Element 78, which is provided in the housing 80 Cavity 79 is introduced. The contact-building Spring 67 comes to rest on the negative EoI of the element, while a screw closure 81 provided with resilient lamellae 82 is screwed onto the housing around which the Completely complete the cavity containing the element.

Those for housing the electrical elements and theirs The required thickness is expediently provided between the bracelet attachments 83 and 84, as indicated above. At this Place the bracelet hides the thickness while on the long sides of the housing is exactly angled at 85 and simulates a small thickness.

Like the I ¹ Ig. 19 shows, a web 86 provided in the housing 80 allows the block containing the elements to be fastened and, to a certain extent, to isolate these elements from the entire movement.

The other components of the clockwork according to the invention are lower in the housing on the platelets, of which in the following the Should be speech!

the I ¹ Ig. 3, 10 »11» 1.2, 22 and 23 are described in more detail.

The watch case 80 (S ¹ Ig. 22) has a circular opening 86 on the front, into which the watch glass 27 fits. The reinforcement ring 88 fitted into the glass holds the glass tight from the inside and forms a seal between the case and the watch glass. The well-ground Sipannring89 allows the watch glass to be pulled out and gives the top of the; Housing a pleasing appearance.

The one carrying the Ssrk with its outer circumference into the housing The fitted circuit board 9® is supported on the latter with its detached one Outer edge. The reinforcement ring resting on the glass holds the circuit board by means of the dial 91 and the insulating washer 92 pressed against the case, laughed the whole clockwork has been introduced through the decorative and clamping ring, so the whole thing is made possible by the close fitting of the watch glass with the Housing together.

The hour hand, the minute hand and the relieved second hand show the time on the dial.

- ^ he plate carries the stones, thrust bearings, and bearings in which the lower pivots of the axes of the individual moving parts turn. This board also supports the individual bridges, which are set in their position / by pins, tenons (or feet) and fastened by screws. The individual bridges also determine the position of the stones and bearings in which the upper ones _; Trunnions of the axes of the individual moving parts run.

measure that the stones and bearings of the bridges are exactly perpendicular over the corresponding stones and bearings of the board come lying down.

The anchor bridge 95 »the one on the board by two screws attached and determined by two pins in the position, has a pivot bearing in which the anchor shaft 27 is rotatably mounted. This axis also turns into one similar pivot bearing, which is fixed in the plate.

The trunnion bearings provide at the same time with an accurate Guiding the axle also protects the pivot pin against impacts (Fig. 23).

The anchor shaft 27 carries the usual Breguet spiral 60 by means of the ferrule 94, which is attached to the eyebolt 95 or eyebolt. The spiral leads between the pins 96, 96 "of the contact fan. The pin 96 ^{! T of} the contact fan is significantly longer than the pin 96. Its lower part is bent at right angles so that it runs parallel to the plane of the spiral The bent part of this: pin prevents the spiral from getting stuck on the bridge or any other point under the action of an impact to correct slightly.
