DE665515C - Arrangement for signaling devices (lute works) in railway systems - Google Patents

Description

The main patent proposes an arrangement for signal systems in railway systems at which the opposite station is blocked if the bell rings from a station be operated. When doing this, the release buttons are pressed simultaneously on both stations pressed, it is not possible to ring the bell from either station without this somehow is shown. A ringing is only possible when the button is released on one side.

This disadvantage is avoided according to the invention in that by pressing a button Address relays that activate a signal when the button is also pressed on the other side, and thereby the line report busy.

The mode of operation of the arrangement according to the invention is described below on an in

ao the illustration illustrated embodiment. A denotes the ringing devices lying in the line, T “ the release button / the ringing inductor, 5 a signal, e.g. B. a flag, W a signal, e.g. B.

* 5 an alarm clock. The relays are provided with capital letters, the associated contacts with corresponding small letters and indices. For each station there is a line relay L with contact I ₁ , a delay relay V with contact v, a push button relay T with contacts I ₁ to t _A , a switch-on relay E with contacts e _x to e _z and an auxiliary relay H with the contacts It ₁ to A _{6 are} provided. The negative pole of the battery used is grounded.

If the button T _{a is} pressed on the left station, the relay T responds via the contacts e ₂ , A ₄ and I ₁ , which is held by itself via the contact t ₂ . By switching contact t _k , the line relay L of the right station _{receives power via contacts A 6} , t ± of the left station, the line with the bell, t _v / I _{1 of} the right station and switches its contact I ₁ . As a result, the relay V _1, which is designed as a delay _{relay, receives current via the contact A 5} and switches the relay E on by closing the contact ν. Signal 5, for example a flag, is actuated by contact e _{3 and indicates that the line is blocked.} Contact e _x short-circuits part of the line relay L and causes it to drop out. The bells / 1 are not triggered by the low current flowing in the line.

On the left station the relay H responds via the button T _a and the now closed contact t ₃ and maintains itself via A _3. At the same time, L now receives power from the right station via the relocated contact ^ ₁

via t _t and A ₁ , but interrupts the circuit of relay T by switching I ₁ , which drops out while H remains pulled. Now the inductor / is connected to the line via It ₂ and ^ _4. The relay V of the left station cannot respond because A _{5 is} open. is. If the inductor is actuated, the bells A are triggered in the line, and the relay L on the right station responds to ίο via its low-resistance winding, actuates contact I ₁ and thus causes V to attract again. V, however, since it is a delay relay, not yet fallen in the time between pressing a key and Abläuten; the flag has so far shown the line occupied. The delay time of V must be a little longer than the time the bell rings in the line to expire in order to ensure that the bell rings safely.

Through the contact e _{2 of} the right station, a signal W, for example an alarm clock, is prepared, which is switched on after pressing the button T _a if the indicator 5 indicating the blocking is not observed and also draws attention to the blocking of the line. If the delay relay V has switched off after its switching time has elapsed, all contacts e and ν return to their original position, and the system is again in the idle state, since the relay L has already dropped out after the inductor pulse has stopped. After releasing the Ta key after giving the inductor pulse, the initial state is also restored on the left station. When ringing in the other direction, the system works in the manner described above due to the symmetrical structure.

If the buttons T _{n are} pressed on both sides at the same time, the relays T and H respond. The alarm clock W speaks via the contacts T _a , e ₂ , t ₂ , A ₄ and I ₁ and reports busy on both sides. If one of the keys is released, the switching process described above begins.

If an earth fault occurs in the line with the bells, for example at point X, according to the further invention the Ljnien relay L of the right station receives current via, t | i &,. Contacts A ₁ , ^ ₁ . By switching jit ^ ttakt I ₁ , the delay relay V becomes

T pull brought, which actuates the relay E via the Kont ν. The indicator constantly points to "busy". When the button T _a is pressed, the alarm clock IV sounds. The corresponding process takes place on the left station.

If an interruption occurs in the line, for example at point X, the relays T and H of the relevant station respond when the button T _{a is pressed.} Since the line relay L cannot respond, the contact ^ remains in the rest position, and the alarm clock receives power via I ₁ , A ₁ , t ₂ , e ₂ and T _a . If the alarm clock rings continuously when the button is pressed, without the indicator being activated, this indicates a line break or some other fault in the system. Of course, this applies again to both stations.

Patent claims: 1. Arrangement for signaling devices (bells) in railway systems according to Patent 652 607, characterized in that when the signaling devices are actuated by the release button (T _a ) on the transmitting station, monitoring relays (E, H, T) respond immediately, which when operated simultaneously on the Keep the opposite station blocked by signals (5). 2. Arrangement according to claim 1, characterized in that in the event of a ground fault Both stations of the line are permanently blocked and this is indicated by a signal (indicator 5). 3. Arrangement according to claim 1 and 2, characterized in that in the event of a line break on both stations when you press the release button (T _a ), a signal (W) is actuated. 1 sheet of drawings
