Addendum to patent 224845 from September 4, 1908. *)

Patented in the German Empire on February 15, 1911. Longest duration: September 3, 1923.

The route protection according to patent 224845 is sufficient in many cases with a busy one The train sequence does not always meet the requirements of the company because of a change of route Too much time is required to operate the switch locks due to the often long distances. Purpose of the invention is now, first, a much faster setting of secured routes when changing routes to make possible under significant shortening of the otherwise long distances to be covered and, secondly, one out of malevolence or, due to gross negligence, possible wrong setting of the course more securely than before to prevent.

The means to achieve these purposes are designed differently depending on the Railway systems of the individual turnout districts of a station require the use of an auxiliary intermediate key and the installation of a second signal lock for a single signal or for several or all signals of a point control area of a train station.

Fig. Ι shows the switches to be operated by a switchman of the track systems of one of the two station heads.
There are:
I and II = the two continuous main

: tracks,

III = the overtaking track for train journeys in both directions,

IV = the shunting or loading track,
A = a two-armed entrance signal, of which A ¹ = the entrance signal for main track II, A ² = the entrance signal for overtaking track III,

B = the exit signal for main track I,
C = the exit signal for overtaking track III,

D = a buffer stop, ■

G = the switchman's room with the later mentioned apparatus located in it,

H = a track board with keyholes 9, 12,

J = a second signal lock for the exit signal B with a 'signal change lock and the keyholes 11, 17,

K = the remote signal lock for the exit signal B with a signal change lock and the keyholes 13, 14,

L = the remote signal lock for the exit signal C with a simple signal lock and the keyhole 19,

M = the room in which the remote locks for the two entrance signals A ¹ and A ^{2 are} housed,

N - the remote signal lock for the entrance signal A ¹ with a simple .Signalschloß and the keyhole 15,

O = the remote signal lock for the entrance signal A ² with a simple signal lock and the keyhole 16;

*) Previous additional patents: 229578, 229682 and 240275.

a, h, c, d are points;
3, 4, 5, 6, 7 are switch locks;
8 is a white twin change lock with the two change locks e and f ;
9 to 19 are keyholes for the matching keys with the same numbers.

Those with this security system after every ■ change of route and after the end

ίο Maneuvering, which is always to be restored, consists of the fact that the two keys 9 and 12 are removed from the track panel H and fixed in switch change locks, namely the key 9 in the change lock 3 of the switch a, which locks it in its straight position is. The key 10 of the interchangeable lock 3 has become free and with it the switch b is locked in its straight position by the interchangeable lock 4. The released key 11 of the shuttle lock 4 has b of the switch frees with the key holes 11 and 17 provided signal change lock of the second signal shutter / for the exit signal B is opened (open), thereby itself set in this second signal lock and the auxiliary intermediate key 17 for further closing work . This means that the two shunting points α and b can only be opened when the key 11 has been released with the key 17 and thus the exit signal B is locked again in the stop position and the key 17 is locked again. With the key 12, which has also been removed from the track panel H , the switch c is locked in its straight position and the key 12 is thereby fixed in the switch interchangeable lock 6 and its key 13 is freed, with which the interchangeable lock of the first lock K (remote signal lock) for the exit signal B. is unlocked. Key 13 is now fixed, but key 14 is now free. With the key 14, the crossing switch d is locked in its straight position by the lock part e of the twin interchangeable lock 8, with the key 14 being fixed. Key 15 becomes free, and with it the remote signal lock N of the entrance signal A ^{1 is} unlocked. As a result, key 15 is fixed in this signal lock. Now the dispatcher can set either the exit signal B or the entrance signal A ¹ or both signals A ¹ and B to clear travel at the same time or, if the switch operator is to set the signals, mechanically or electrically release the signals.

If a train coming from E is now to enter the overtaking track III, the key 15 can be removed from the signal lock of the remote lock N , whereby the signal A ^{1 is} locked again in the stop position. Then the switch d is unlocked with this key 15 through the lock part e of the twin interchangeable lock 8 and turned into its crooked position and locked in its crooked position with the key 14 released by the unlocking. Key 14 is set in interchangeable lock 7 and the one that has become free. Key 16 is used to unlock the remote signal lock O of the signal A ² .

If a train from the overtaking track III is to travel from F to E on the main track I and the signal C intended for this is to be set to free travel, the key 15 or key 16 is to be taken from the remote signal lock N or O. As a result, the entry signal A ¹ or A ^{2 is closed} again in the stop position. Then the crossing switch d is unlocked with this key and the key 14 is free again. Now the switch d is locked in its straight position by the lock part f of the twin interchangeable lock 8 with the auxiliary intermediate key 17, thereby locking the key 17 and freeing the key 18. Now the exit signal B is first locked in the stop position with the free key 14 and the key 13 in the signal change lock of the remote lock K is free. The switch c is unlocked with the key 13 and the key 12 that has become free as a result is removed from the switch lock 6. Then the switch c is turned over and locked in its crooked position by interchangeable lock 5 with the key 18 obtained from the lock part f of the twin interchangeable lock 8, whereby key 18 is set and key 19 is released, with which the signal C is then unlocked by the remote signal lock L. and can now be put to free travel. Meanwhile, key 12 is held in control panel H. .

If all switches and all tracks are to be used for maneuvering, the key 15 is to be taken from the signal lock for the entrance signal A ¹ , whereby this is locked in the stop position. Then the junction switch d is unlocked with key 15 and thereby key 15 is determined, while key 14 is released. With this the exit signal B is locked in the stop position and thereby the key 13 from the signal change lock of the remote signal lock K is released. The switch c is unlocked with the key 13, thereby determining the key 13 and freeing the key 12 with which the control panel H is set. Then with the auxiliary intermediate key 17, the second signal lock / the exit signal B

locked for the second time and thereby set the key 17 and the key 11 of the signal change lock for the second Sign al lock / free. With this key 11, the switch b is unlocked, thereby determining the key 11 and freeing the key 10. With this key 10, the switch a is then unlocked and thereby key 10 is determined and key 9 is released, with which the control panel H is also set, in which the key 9 remains until after maneuvering is completed. Of course, instead of the switch lock 3, a simple switch lock can also be used. However, a change lock has been chosen to prevent unauthorized locking of the switch 3 and removal of the key during the maneuvering movements.

If only the main track I and the shunting track IV are to be maneuvered using the turnouts a, b, c , and if the maneuvering is to take place on the main track II and on the overhaul track III, then the turnout c remains locked in its straight position, however the first lock K of the exit signal B is opened in order to be able to lock the crossing switch d with key 14 either in its straight or in its crooked position and daduixh the key 15 that matches either the entrance signal A ¹ or the key 15 that matches the entrance signal A ² 16 to attain. However, the exit signal B must now be locked in the stop position by the second signal lock / with the auxiliary intermediate key 17, firstly so that it cannot be set to free travel during the maneuvering movements, and secondly, to the key .11 to unlock the switch b to vacate. If the switch b is then unlocked with the key 11, the key 11 is fixed in the switch change lock 4 and the key 10 is free. With this the switch α is unlocked, whereby the key 10 in the switch interchangeable lock 3 has been determined and the key 9 has been released, which remains in the track board H until the end of maneuvering.

FIG. 2 also shows the switches of the track systems of one of the two station heads of another station system to be operated by a switch operator.
There are:

V, VI, VII and VIII = the main tracks, of which V and VII only in the direction from Sch to St and

Track VI and VIII may only be used in the direction from St to Sch ,

IX and X = loading and shunting tracks outside the routes to be secured,

. XI = a connecting track,

N = a two-armed entrance signal, of which N ²⁰ = the entrance signal for track VI,

2V ²¹ = the entrance signal for the overtaking track VIII, 0 = the exit signal for track V,

P = the exit signal for track VII to St,

Q = stand,

R = a second signal closure for the four signals IV ²⁰ , N ²¹ , O and P,

S = a track board with keyholes 34 and 37,

T = a buffer stop,

g, h, i, k, I and m = switches,

η = remote signal lock for the exit signal N with the keyhole 35,

0 = remote signal lock for the exit signal 0 with the keyhole 36,

■ p = remote signal lock for the entrance signal N ²⁰ with the keyhole 39,

q = remote lock for the, entrance signal N ²¹ with the keyhole 40,

22 = a track block depending on the switch / 24 to 30 interchangeable locks,

31 to 40 keyholes for the matching keys with the same numbers.

In the basic position, the switch g is locked in its straight position with the key 31 and the keyhole 32 of the interchangeable lock 24 is free. The switch h is locked in its straight position with the key 32, and the keyhole 33 of the interchangeable lock 25 is free. With the key 33, the second signal lock R is unlocked for the four signals iV ²⁰ , iV ²¹ , 0 and P and the key 33 is thereby fixed in the second signal lock R. The keys 34 and 37 have been removed from the track panel S. It is locked with key 34, the switch i in its straight position and thereby set key 34 in the interchangeable lock 26 and its keyhole 35 free, while in the other interchangeable lock 27 to close the switch i in its crooked position, the key 36 is fixed and the keyhole 34 is free is. The now free key 35 is fixed in the simple signal lock η of the remote signal lock η and the exit signal O is unlocked as a result. With the key 37, the switch / is locked in its crooked position and the key 38 of the interchangeable lock 28 is free. As a result, the track barrier 22 is set to secure the main tracks on the rail. With the key 38, the switch k is locked in its straight position and the keyhole 39 of the interchangeable lock 29 is free, while in. the other interchangeable lock 30 for locking the switch k in its crooked position of the key 40 fixed and keyhole 38 is free. With the now free key 39, the remote signal lock ft

drive signal IV ²⁰ unlocked and thereby set key 39 in the simple signal lock p .

The dispatcher can now set either the entry ^{signal N 20} or the exit signal 0 or both signals IV ²⁰ and 0 at the same time to open travel and then to stop again.
If the exit signal P is now to be set to free travel, the key 35 is to be taken from the remote signal lock η , whereby the exit signal 0 is locked again in the stop position. Then the switch i is unlocked with it, turned over and locked in its crooked position with the key 34. With the key 36 that has become free as a result, the exit signal P is then unlocked in the remote signal lock 0 and pulled into free travel by the dispatcher or the switch operator.

Should the entrance signal N ^{21 set} to free travel

are set, the key 39 can be taken from the remote signal lock φ , whereby signal N ^{20 is} locked again in the stop position. Then the switch k is unlocked with it, turned over and locked with the key 38 in its crooked position. With the key 40 that has become free as a result, the signal 2V ²¹ is then unlocked in the remote signal lock q and can be set to free travel by the dispatcher or the switchman.

If vehicles are to be transported from track V to track VI or vice versa from track VI to track V, the key 33 can be taken from the second signal lock R for all four signals. As a result, they are locked in the stop position. Then the switch h is unlocked with the key 33, whereby the key is fixed in the interchangeable lock 25, while the key 32 is released.

With 32 switch g is unlocked, whereby it is set in interchangeable lock 24 and key 31 is released. Of course, a simple switch lock can also be used in place of the interchangeable lock 24. However, an interchangeable lock has been chosen to prevent unauthorized locking of the switch and removal of the key.

If all turnouts are to be maneuvered on all tracks, all turnouts are unlocked backwards. In cases where only tracks VI, VIII, IX and X are to be shunted, but trains are to leave main track V and overhaul track VII to St during shunting, only the two points / and k are unlocked, which means the two entry signals N ²⁰ and iV ²¹ are locked in the stop position, while the two switches k and g remain locked in their straight position and the second signal lock R remains unlocked. This is best always located in the switch booth Q, while the remote signal locks are most advantageously always arranged in the vicinity of the last ζια locking switches, i.e. the remote locks η and 0 near the switch i, whereas φ and q near the switch k .
