Adjustment device for points, signals, etc. Patented in the German Empire from October 22, 1931

It is well known that electrical actuating devices for switches and signals are used a monitoring magnet for each switch or signaling device, which is only used in the End position of the turnout drive and the corresponding position of the control lever receives power. For this purpose, there is a contact on the control lever and one for each position of the switch provided on the control switch of the point machine, via which the current to the Monitoring magnet is guided. The second contact on the control switch and the other contacts on the wiring system are not monitored, which can result in an external current in one of the lines penetrates and activates the point drive motor via the relevant contacts or the monitoring magnet that has fallen off for any reason.

ao pull brings.

You can protect yourself against some of the external currents by using the monitoring current one after the other via one control line, then via the monitoring magnet and then via the other control line leads. However, one cannot and cannot "counteract all malfunctions" with it monitor all contacts.

The invention aims to achieve monitoring of all contacts and is based on the knowledge that all of them are not using the normal monitoring current Contacts occupy such a position that it is possible to jointly apply a special monitoring current via them send. According to the invention, therefore, the circuit; the each of the monitoring current contains unused contacts, connected in parallel to the existing monitoring current to the power source and in this circuit a test magnet is arranged, which this second Circuit monitors the same way as the well-known monitoring magnet monitors the normal monitoring circuit of the turnout or switch. of the signal.

The subject matter of the invention is explained in more detail in the figures.

Fig. Ι shows the idle state of the facility. The monitoring current flows from the Power source 1 via line 2, control lever contact 3, line 4, control switch contact 5, Line 6 and the two consecutive windings 7, 8 of the monitoring magnet, spring switch contact 9 and see tion 51 back to the power source. The one winding 7 of the monitoring magnet is "bridged by a contact 10 interrupted in the rest position on the spring switch, which is operated in a known manner when turning the control lever and when running out of the point machine is returned to its original position by a spring.

According to the invention, there is now, for example, in the line 11 from the current source 1 leads to the drive motor 12, a test magnet

13 provided over which a current is sent takes the following route: from the power source ι via the spring switch contact 14, test magnet 13, resistor 15, Control lever contact 16, line 17, control switch contact 18, drive motor 12, line 19, spring switch contact 9, fuse 51 back to the power source. As you can see from the figure, all of them are for one possible actuation of the monitoring magnet 7, 8 and the drive 12 in question Checked contacts.

Figs. 2 to 6 show in sequence the current flows when the switch drive is actuated.

In Fig. 2 it is assumed that the lever is thrown to the switch in the to bring another location. Here, the two contacts 3 and 16 are moved. Of the ao actuating current which either comes from the same current source as the monitoring current or from a special current source with higher voltage, which is connected to the line when the control lever is turned, now takes the path shown via parts 2, 3, 20, 17, 18, 12, 19, 9 to the return pole of the power source. By turning the lever, both windings of the monitoring magnet are closed has become de-energized, so that it has fallen off and at the same time that which is on it Contact 87 has closed. The test magnet 13 is by breaking the spring switch contact 14 has also fallen off and has turned over the contact 31 located on it. The meaning of the contacts 31, 87 and 10 will be seen later.

As soon as the engine starts to run, the contact 5 is switched and takes the dashed line position shown. As soon as the engine has stopped, the contact is made too 18 and thus the actuating current is interrupted. The result is then the length according to fig. 3. Here the current flows from the current source 1 via the parts 2, 3, 20, 17, 18, 6, contacts OK, 31, winding 8, contact 9 back to the power source. The monitoring magnet 8 receives contact via the spring switch 10 electricity. This triggers the spring switch and the contact. 10 interrupted, so that the monitoring magnet is de-energized again, as shown in Fig. 4 evident. At the same time, the spring switch contact 14 is turned over again been, and the current now flows from the power source 1 via the parts 14, 13, 87, 16, 21, 4, 5, 12, 19, 9 back to the power source. The test magnet 13 attracts and switches the

Contact 31 around so that the monitoring current is now switched on, which now, 60 as shown in Fig. 5, takes the following path: from the current source 1 via parts 2, 3, 20, 17, 18, 6, 7, 31, 8, 9 back to the power source. The monitoring magnet picks up again and interrupts contact 87, so that the position shown in Fig. 6 now results. Here, the normal monitoring current flows from the power source 1 via the parts 2, 3, 20, 17, 18, 6 and the windings 7, 8 back to the power source, 7 ° while the monitoring current added according to the invention from the power source ι over the parts 14, 13, series resistor 15 and the parts 11, 16, 21, 4, 5, 12 come back to the power source. 75 As can be seen from the circuits at the same time, it is not necessary to switch on a special test magnet in each of the two lines 2 and 11; The line 2 and the contact 3 are therefore always monitored by the normal, known monitoring magnet 7, 8, which, however, is provided with two windings ⁸ 5 here.
