this lock.

Patented in the German Empire on February 8, 1907.

The subject of the invention is a device on electrical switch control and monitoring devices through which an automatic electrical locking of the Switch tongues in their end positions and a monitoring of this locking causes without the need for special circuits or other manipulations.

In Fig. Ι the simplest form of the on-order is shown. In the usual way, current is supplied through a switch lever / and through the lines ι and 2 of one or the other of the two field magnet windings m ^l and m ² and the armature of the electric driving machine m , so this is put into circulation in one direction or the other The return of the current or the earth connection takes place through the line 6. The Treibrnaschine moved in a manner known per g by the countershaft and the rack α the switch points \ and opens after completion of each assignment automatically those of the contacts n \ ή ^2, which had supplied thereto the operating current, but includes for the opposing contact o ¹ or o ~, which sends a current to the control magnet k through the line 7, 8, 3. This indicates that its armature is applied to recognize that the driving machine contact o ¹ or o ^{2 is} closed, so the driving machine has properly completed its way.

The following new arrangement has been made on this known device: With each of the two switch tongues, a slide b is connected to each of the two switch tongues Lock piece c is located. This locking element is connected to the armature r of a switched between line parts 7 and 8 electromagnet connected so that on the one hand, the locking piece c can not be lifted, when the electromagnet r is crossed by the current, on the other hand, the electromagnet r anchor just can attract when under the locking piece c there are incisions of the slide b , the switch tongues \ are in their end positions. The position of the electromagnetic armature after the attraction has taken place is monitored by a contact s through which the control line 8, 3 is routed. A second contact t , while the contact s is open, connects the line 7, 8 to the return line 6, so that the electromagnet r can receive current and can be caused to attract its armature.

The position of the parts in Fig. 1 corresponds to the one rest position of the switch blades ^. The two tongue sliders b are positioned so that their rear incisions coincide with the position of the locking piece c . The switch lever is located at the contact /, the field magnet winding m} of the traction machine is by opening of the contact n ^{1 is} turned off, the m for the winding ² serving contact n ² but closed. It flows through the mag-

Neten k a control current (the points at which the control currents exert a monitor, are in subsequent circuit information by underlining the bodies 5 in which the control is made visible) in (control magnets by double underlining): - \ - /, i, o \ 7, r, 8, s, 3, k -, which at o ^{1 means} reaching the end position of the driving machine, at s the

locking of the tongues controlled. Only when these two contacts are in order does the electromagnet k attract its armature and give the sign corresponding to the orderly state (white window f).

If the switch lever is thrown so that it closes the contact 2, the control current flowing through the magnet k is interrupted, the armature drops out, the window / turns black. At the same time, the armature of the electromagnet r drops, the locking of the tongue slide b is released, and the contact t is closed. With the current + /, 2, ri ² , m ² , m, 6 - flowing now, the driving machine starts up and first closes the contact n ^l . After completing its path, it opens contact n ² and closes o ² . At this moment the motor current is interrupted and a current - | - /, 2, o ² , 7, r, 8, t, 6 - flows first. Through this, the electromagnet r attracts its armature, locks the tongue bars b when they have reached their other end position, and switches instead

₃ g contact sets the contact s on . Now the control current flows -f- /, 2, o ² , 7, r, 8, s, 3, k -, which monitors the new end position of the motor ^{at o 2 and} the locking at s.

Since the bolt ^{current goes through contact o 2} , it cannot flow until the driving machine has reached its end position.

It should be incidentally noted here that only the simpler explanation, the locking device is shown so that the movement of the tongue, which by the locking ^ver: should be prevented, acts on tearing of the solenoid armature. This effect can be avoided, for example, by the arrangement shown in FIG. ! The locking piece c is driven here by spring force into the notches of the slide b as soon as they are under it, and this part is then electrically locked at χ.

It is also advisable to use two instead of the one locking piece c , both of which are locked by the electromagnet r as shown in FIG.

The two groups of incisions in the tongue slide b can then be arranged as far away from one another as desired.

Also, in a known manner, the two tongue sliders b on a common moving member, for. B. act on a third slide connected to both by a rocker arm, which is locked in its position caused by the proper position of both tongues in the manner described by the electromagnet.

The arrangement described thus far shows the drawback that the control magnet k and then the orderly state of the device indicates when the turnout ⁷ ^ tongues are able to / does not match the position of the switch. The control current would flow in exactly the same way in Fig. 1 if the switch were brought into its opposite position, ^ ⁰ so that the locking body c would be in the rear notches of the tongue slide b .

If you want to prevent this, two locking magnets can be arranged, one of which is used for each tongue position. Such a device is shown in FIG. 2. Separate lines J ^a and y ^{b lead from the contacts o 1} and o ² to the ^{locking magnets r 1} and r ² , the armatures of which each lock a locking piece c ¹ and c ² . The lines from contacts s ¹ and s ² combine to form control line 3, those branched off from contacts t ^l and i ² lead into return or earth line 6. In the rest position shown, the control current + /, o \ 7 ^{a flows} , r \ 8 ^a , s \ 3, k -. If the switch tongues were to be brought into the opposite position, the locking piece c ¹ would be lifted and c ² would insert itself into the rear notches of the tongue slide b. The contacts s ^l and i ² would be open, i ¹ and s ^{2 would be} closed. The current + I, 1, o ¹ , r \ 8 ^a t \ 6 - would go to earth, so the control magnet k would drop its anchor. The proper status is only reported when the switch is in the position of the shift lever / corresponding position.

In the arrangements described so far, the latch rhagnet r can only attract its armature if the associated latch piece c, c ¹ or c ^{3 was} properly entered into the notches of the tongue slide b; Otherwise, a mechanical obstacle will make it impossible to tighten the anchor. One more . However, greater security is provided by a device in which, in the event that the locking piece has not properly entered the notches of the tongue slide, that is, the correct position of the tongues is not guaranteed, a control current does not come about at all

can come. In this case, the armature of the locking magnet r can be tightened safely, even if the tongues are not positioned correctly.

Such a device is made possible by the arrangement of a contact u ¹ and u ² (Fig. 3) on the two locking pieces c ¹ and c ² , which is only closed when the corresponding locking piece is in the associated incisions of the tongue slide b . The control current is conducted via these contacts. If in this case the control magnet k is only to report an orderly state when the position of the switch lever / corresponding tongue end position has been reached, two control lines 3 ^a and 3 * (one for each end position) must be arranged, their connection with the control magnet k produces a switch ρ that is always thrown at the same time as the switch lever /.

In the idle state shown, the control current -J- I, 1, o \ 7, r, 8, s, u ¹ , 3 ", p, k - flows. This controls the end position of the driving machine ^{at o 1 and} the correct position at s of the armature of the locking magnet r, at u ¹ the correct position of the locking piece c ^l , i.e. the switch tongues.

, ₀ lever / and at the same time the switch p is thrown with it, the control current is first interrupted, the armature of the bolt magnet r drops out, and the contact t closes. A current now flows -f- I, 2, n ² , m ² , m, 6. -, which sets the driving machine into circulation. This first opens the contact o ¹ and switches on n ¹ for this. When the switch begins to move, contact w ^{1 is} opened, after the move w ^{2 has been completed, it is} closed, and finally the driving machine switches on contact o ² instead of contact n ² . The current + Z, 2, o ² , 7, r, 8, t, 6 ■ - flows through which the locking magnet r attracts its armature. This causes the electrical interlock and instead of the contact t the contact s is switched on, and the control current -f /, 2, o ² , 7, r, 8, s, u ¹ , 3 *, p, k - now flows.

An arrangement in which the locking q takes place only through apportionment of the driveway lever and separate control magnets k ¹ and k ² for monitoring the Treibmaschinenendlagen one hand and for monitoring of the blade end and the locking on the other hand are present, Fig. 4. q From the route switch whose known dependence on the position of the shift lever / is not indicated in the drawing, a line leads to the latch magnet r. The control lines 3 "and 3 *

are used alternately to feed the driving machine control magnet A: ¹ and the bolt control magnet k ² . These lines are therefore connected directly to contacts o ¹ and o ² and connected to the switches of contacts u ² and w ¹ , which monitor the tongue end positions. In the position shown, the two control currents ^{flow through -k l} : - \ - I, 1, o \ 3 ", J? ¹ , k ¹ -, through k ² : + q, 4, r, 8, s, u \ ^ ^b , p ² , k ² -.

If the route lever q is brought into the rest position, the second of these currents ceases, the armatures of the control _{magnet y 5} neten k ² and the locking magnet r drop, and the contact s is swapped with t. If the switch lever I is now also thrown at the same time as the switches p ¹ and p ² , a current flows - I, 2, n ² , m ² , m, 6 - which sets the driving machine into circulation. Instead of the contacts o ¹ , u ¹ and n ² , o ² , u ² and n ^{1 are} closed. It then flows through the control magnets k ¹ of the control current + / 2, O ^2, 3 *, p ^1, k ¹ -. If the drive / road switch is thrown, a current + q, 4, r, 8, t, 6 - flows, which attracts the armature of the bolt magnet. This creates the current flow + q, 4, r, 8, s, w ² , 3 ^a , p ² , k ² -, which indicates by the control magnet k ² that the tongue position and the locking are in order.

Since, in contrast to the arrangements described above, the line 4, which supplies the bolt current to the electromagnet r , is not routed via the contacts o ¹ , o ² , the bolt movement of the magnet r is not dependent on the closure of these contacts. It can even cause the magnet latch his movement and interchange of contact · s t against the contact before the blowing machine has come to its end position when only the driveway switch is on q. In order to avoid this, the dash- dotted part of the line leading from the contact t to the return line 6 in FIG. 4 can be replaced by the dotted line 5, which is connected via the contacts i ^l and r which close simultaneously ^{with the contacts o 1} and o ² is performed, so that a current can flow through the magnet r again only when one of these contacts z ¹ , i ^{2 is} closed, so the driving machine has reached its end position. '

Fig. 5 shows how this arrangement can also be carried out for two separate locking magnets r ¹ and r . The circuit in the signal box itself remains the same as in FIG. 4, and the following changes have only been made on the point machine. Line 4 switched on by route switch q

is divided and each branch is fed to ^{one of the magnets r 1} and r ^2. The lines connected to the contacts i ¹ and i ² are routed via the tongue slide contacts n \ z < ² , so that the bolt movement cannot occur until the switch tongues have properly reached their end position. Switching on the contacts n ¹ , u ² in the control line is therefore dispensed with. The control line 3 ^a is connected to the contact s ~ of the magnet r ² , the control line 3 * to the contact s ^{l of} the magnet r ¹ .

In the position shown, the following flow

* 5 control currents through k ¹ : + /, 1, o \ 3 ", p ¹ , k_ ^l -, through k ² : -f q, 4, r \ 8 ^a , s ^l , 3 Vp ² , k ² -. that inspected again at o ^1, the end position of the traction machine, this at s ^l the locking state. the tongue position is in this case not monitored by the control current, since this does not go beyond the contact u ^1, however, the control is provided by the fact that, as from the The following can be seen, no latch current can come about if u ^{1 is} not closed.

If the route switch q is put to rest, the control ^{current flowing through the magnets r 1} and k l stops. Contact s ^l is swapped with i ^1. By moving the switch lever / together with the switches p ¹ and p ² , the current -j- /, 2, n ² , to ² , m, 6 - is obtained. The driving machine runs and exchanges the contacts o ¹ , ii ^l and n ¹ for ή ¹ , u ² and o ² , whereupon a control current + I, 2, o ² , 3 *, p \ kf - flows. The control magnet k ¹ thus monitors the contact o ² . If the route switch is thrown again, a current flows.-F- q, 4, r ² , 8 *, f, u ² , 6 -. This results in the bolt movement and the interchanging of the contact i ² with s ² , whereupon the control current -f- q, 4, r ² , 8 ^b , s ² , 3 ", f, If - flows through the magnet k-.

While in FIGS. 4 and 5 the line 3 ^a or 3 * not required for checking the driving machine end positions by the magnet k ^{l is used} for bolt monitoring by the magnet kr , FIG. 6 shows an example of the control lines being used 2> ^{a and} d 3 * used exclusively for the magnet k ^l , but the bolt monitoring is effected by the magnet k ² with the help of the control lines 1 and 2.

For this purpose, the lines 3 ″ and 3 * are only placed on the contacts of the switch p ¹ , which is connected to the magnet k ^l , and the line of the controlling contact 5 goes through the contacts μ ¹ , M ² and ends in the contacts n ¹ and n ^{2 of} the control lines 1 and 2, which in turn with

the two contacts of the latch control magnet k ² operating switch p ^{2 are} connected. In order to prevent the bolt control current from flowing out via the driving machine m into the return or earth line 6, this is interrupted and at w is routed via a contact which is only closed when there is no interlock. To the entry of the bolt movement here to make the magnet r dependent on the completion of the blowing machine path is out of contact t connected latch line again, as shown in the dotted arrangement of FIG. 4, via contacts z ¹ and z ^2, which from the traction machine be closed at the end of their movement.

In the position shown in FIG. 6, the two control currents flow: Through k ^] : - \ - I, I, o \ 3 ^b , p \ V -, through k ² : + q, 4, r, 8, £, M ¹ , n ² , 2, p ² , P -.

If the route switch is brought to the rest position, contact s opens and t and w close. The control current in k ² stops. After moving the switch lever I together with the switches p ^l and p ² , a current flows -f /, 2, κ ² , m ² , m, 6, w, 6 -. The driving machine runs and switches on the _go contacts n ¹ , o ² and u ^{2 instead of the contacts o 1} , n ² and u ^l , whereupon the control current - | - /, 2, o ² , 3 ^a , p ¹ , k again ^l - flows. If the route switch q is thrown again, a current flows - \ - q, 4, r, 8, t, i ² , 6 -. This causes the locking, opens the contacts t and w and closes the contact s, whereupon the control current + q, 4, r, 8, s, u-, n \ 1, p ² , k ² - flows.

While in the cases discussed so far, where a special route switch is used (Fig. 4, 5 and 6), six lines were required between the signal box and the point machine, Fig. 7 shows an example of the solution to the problem with only five lines. A third switch, p ^s , ¹⁰ S, which is moved with the switch lever / or with the route lever q , is arranged and sends the current flowing through the route switch alternately to the two control lines 3 "and 3 * and through them via the contacts u ^l , u ² the latch magnet r. the control solenoid k ^'2 receives its power through the respective free Stel line 1 or 2, the control solenoid k ¹ again, as shown in Fig. 6, by the free con- ¹¹ S trolleitung 3 "or 3 *. Otherwise, the circuit can be seen in the drawing.

In the position shown in Fig. 7, the control currents flow: through k ^l : -f- /, 1, o ¹ , v ² , 3 ^a , p \ If--, through A " ² : -I- q, f, 3 *, u \ r, 8, s, n ² , 2, p ² , k ² -.

After turning the route switch q , the contacts s and n> are canceled and the contact is established at t . If the switch lever I and the three switches p ¹ , p-, j> ^{3 are} thrown, a current flows -) - / ² , n ² , nr ² , m, t, 6 -. The driving machine is running, removes the contacts o ¹ , w ² , M ¹ and v ² and switches on n ¹ , o ² , v ¹ and m ² . The new control stream takes the course - \ - I, 2, o ² , v ¹ , 3 ^b , p ^l , k ^l -. By turning the route switch q one obtains the current -j- q, p ³ , 3 ^a , M ² , r, 8, t, 6 -. It is locked, the contact t is canceled and the contacts s and w are established. Now

the control current flows -J- q, p ^s , 3 ", w ² , r, 8, n>, η ¹ , ι, ρ ² , k ² -, which monitors the position of the tongue ^{at m 2 and} the lock at w.

In Fig. 8, finally, an example of an arrangement is shown, for which only five lines are also required and which effects the monitoring of the driving machine end positions and the switch locking with a single electromagnet, in such a way that in cases where the route switch is not used such as B. when maneuvering, the magnet only controls the end positions of the driving machine, but if the route switch is thrown, 'also monitors the locking. The device on the point machine is the same as in Fig. 7, only the interlocking system differs from it. In essence, the change is that with the route switch, a second switch q q ¹ is connected, through the lines 3 ^a and 3 ^έ the one hand and 1 and 2 can be connected alternately k to the control magnet on the other.

In the rest position shown in FIG. 8, in which the route switch is assumed not to be pulled, a control current flows - \ - I, i, o ¹ , v ² , 3 ^a , p ² , q \ k -. This indicates through the contact o ¹ that the driving machine

has reached its end position. If the route switch q is now thrown with the switch ^{q 1} , the above-mentioned current via q ^{1 is} interrupted, the magnet k thus drops its armature. But then a current flows + q, p \ 3 *, u \ r, 8, t, 6 -. The locking takes place, contact t is opened, s and w are closed. Now the control current flows -f- (Z _1- P ¹ I 3 ^b > u ¹ , r, 8, s, n " ² , 2, p ³ ,

-, q ¹ , k -, which monitors the position of the tongue at u ¹ and the locking mechanism at s.

If the driveway switch q with the switch q ¹ put back into the rest position, the control flow is interrupted, thus contact s and w t canceled and closed. If the switch lever / with the switches ρ ', ρ' ² and ρ ^{3 is} thrown to switch the switch, a current flows -) - /, 2, η ² , m ² , m, t, 6 - that controls the driving machine puts into circulation. The contacts o \ η ^λ , u \ v ² are exchanged for n ¹ , o ² , v ^l , u ² , and a control current -f- /, 2, o ² , v \ 3 ^έ , ^ ² , q flows ¹ , k -, which monitors the end position of the driving machine ^{at o 2.} Then, when the route to the switch switches q q ^l is closed again, this current is interrupted ^l at q, and a current flows + q, p \ 3 ^α, κ ^2, r, 8, t 6 -. The locking and the cancellation of the contact t takes place, for which s and w close. The current now takes the path -f q, p ^l , 3 ^a , u ' ² , r, 8, w, n \ i, p ³ , q ^l , k -, so controls the tongue position at u ² and at u> the lock.

If you want to prevent current from possibly neighboring conductors from getting into the control lines and causing a false message, the switches that interrupt the control lines can be provided with contacts that connect them to earth. The ₅ s simplicity, are omitted in the drawings, these switches and lines.
