Signal circuit for multi-car trains

Patented in the German Empire on February 28, 1931

In the case of signaling devices for vehicles, it is essential for proper, safe operation required that the stop signal is given as soon as one of the conductors his signal switch brings into the stop position that the driver receives the travel signal but only after all conductors have activated their signal switch have given the appropriate command. If optical signaling devices are used for signaling, one can Arrange the circuit so that the circuit for the given signal lasts as long remains until it is executed by the guide, or in the case of an existing travel signal this is canceled by a new stop signal. This arrangement is not to be used with acoustic signals, because the guide is disturbed too long by the signal being heard for too long. One therefore has

ao already proposed the contact of the signal switch to keep the conductors' seats closed only as long as the conductors hold the signal cord or the push button in the switch-on position. Here it is

as required that to give the travel signal each conductor keeps his signal switch in the on position until all conductors have their signal switch in the same position and thereby over the in-line travel contacts of all signal switches the circuit for the travel signal has been closed at the driver's cab. But this arrangement just makes the advantage that you get with the electrical signal systems wants to achieve in vehicles and that is that each conductor is independent can give the driving signal from the other conductors after his car has been cleared.

The present invention now provides an acoustic signaling device for vehicles in which the disadvantages set out above are avoided. According to the invention proceeds the circuit for the travel signal via contacts in series with self-locking Relays, one of which is housed in a vehicle and only from the travel signal switches of the associated car can be excited, and a contact of a relay, which when each travel signal switch is actuated is excited for the duration of this actuation. The travel signal is only activated when the last travel signal switch is actuated switched on and only kept switched on as long as the last one operated Signal switch is held in its working position.

This arrangement ensures that the travel signal only sounds as long as the Finally, the conductor giving the drive command has his signal switch in the working position holds without it being necessary. that the other conductors put their signal switch Hold in the working position until the last switch is pressed.

game of the invention shown. An acoustic signal S _t or S _{2 is} provided in the driver's cabs of the railcar, which serves as a travel, stop and emergency signal «. Furthermore, changeover switches U ₁ and U ₂ are arranged in the driver's cabs, with which the signal S ₁ or S _{2 can} be switched so that it is in the one direction of travel in which the driver's cab on which it is located is the front one, serves as an emergency signal and in the other direction of travel, in which the driver's cab is the rear, as a communication signal from the driver to the conductor by a push button / C ₁ bsw. Ji ₂ can be operated by the operator. The switch is inevitably z. B. made by the direction roller.

_{Push buttons F 1} , F ₂ , F ₁ ', F ₂ etc. for giving the travel signal and push buttons H ₁ , H ₂ , H ₁ etc. for giving the stop signal are arranged on the conductors' stands. In addition, relays A, A ' , etc. are arranged in the car, which are in the circuit with the travel buttons and. when excited, the associated contacts A ₁ , A ₁ , etc. close, which automatically lock in their working position, so that they remain attracted regardless of the excitation of the coils A, A ', etc. The latching of the contacts can be released by the relays C ₃ C etc., which are energized via the stop push buttons. In series with the coil A, A ' etc. in the motor vehicle there is a relay E and in series with the coils C ₁ C there is a relay D. The battery B is used to supply all electrical circuits.

The mode of operation of the arrangement is as follows: By pressing a departure button F ₁ or F ₂ , the coil of the car in question and in series with it the relay E in the railcar is energized. The contact. ^ Of the energized relay A is kept closed, but the departure signal can only sound in the driver's cab when the conductor of the car that was last checked in has given the departure signal. As long as this conductor keeps the travel button pressed and thus keeps the relay E in the railcar energized, the following circuit is for the acoustic safety

- gnal ^ i closed: battery B ₃ signal S ₁ , changeover switch U ₁ , contacts E ₁ , A ₁ , A ₁ , A ₁ ', earth.

To give the stop sign, one of the stop buttons H ₁ , H ₂ , H ₁ etc. is printed twice. If z. B. is given the stop sign with the button H ₁ , the relays C ₁ Ci and C " all respond, so that the contacts A ₁ , A ₁ , A ₁ " are unlocked and open. By the relay D in the railcar, which responds in series with the relay C, the signal S ₁ is brought to ground at the contact D ₁ for sounding. Since all contacts. ^ Have been opened when a stop button is pressed, all conductors must press a travel button before the travel signal is given.

To give the driver the signal to stop immediately, a stop button is pressed three times. The relay D responds three times and causes the signal S ₁ to sound three times via its contact D _1.

If the driver wants to give a signal to the conductor, he presses the button UC ₁ , whereby the signal S _{2 is made} to respond. The corresponding push button K ₂ on the rear platform is _{short-circuited via the switch CJ 1} in this direction of travel, so that it cannot respond to the emergency signal S _{1 if it is actuated from the unsolicited side.}
