SU26344A1 - Hub to Morse telegraph machines - Google Patents

Description

It is known to use the point where several telegraphic and single concentrators for Morse type devices converge, which have the disadvantage that they have a good working device for a call and do not have 1 Nl device for selection.

The hub according to the invention differs from the already known constructive form of the device for calling and tapping.

The drawing shows a schematic diagram of a hub on direct current with two terminal stations of the Morse type, in this case, using klopferov.

The hub-has a device for the call, performed as follows. The working clamps of the keys. Lorze Km of terminal stations are shunted by resistance R in such a way that when the key is raised, the current circulating in the circuit weakens, for example, to 5 milliamperes. For klopferov, working at a greater current strength, for example, 15 milliamperes, this is equivalent to breaking the circuit and they release their measles. The LR relay is installed in the hub; adjusted so that it keeps its measles pressed and at the same time an incomplete break

circuit, release it only when the circuit is completely broken switch P, normally closed.

When the key is pressed, the current in the circuit circulates as follows: plus battery B, key Km klopfer Kl, contact. P, normally closed, line L, galvanoscope of the hub Gl, sensitive linear relay LR, contact / interrogation socket Og. earth and minus battery.

When the key is raised, the current continues to circulate and only with a complete break in the circuit of the switches P, the linear relay LR closes contact 5, turning on the call relay BP, which will work and that both the cores will turn on. Left-handed measles will turn on the overhead lamp. The current in this case circulates as follows: luce of the battery, contact 4, measles, calling lamp VL contact 2 of the Og and minus of the battery. The lamp ignites. The second (right) measles will block the relay and will keep it under current until the contact5 opens, i.e. when, the relay R. Plus battery works again, the relay BP, contact 5, measles, contact 2 Og and the battery minus.

The person on duty, having seen that the overhead line calling lamp, corresponding to a certain wire, was lit, will insert a single-wire

interrogation plug Osh to interrogation socket 0g. When the plug is inserted, the long springs break up and the contacts 7 and 2 are diluted. This breaks circuit 4, i.e. Callinoguele LR releases measles and the lamp goes out. The lower spring has an insulator at the end and is thus not electrically connected with the O-plug. Then body lkaetac contact 7 and the linear relay, and with it the line is disconnected from the ground and is included in the attendant clopfer, which talks to the calling station ..

Thus, a circuit is established: plus batteries, / SUP, CL, P, L-line, / and, LR, Og, Osh, contact C, which is in position; About (survey), control kloffer K K, key on duty K Km and minus the battery.

The klopfer work with a non-full rupture does not respond to the LR sensitive linear relay and it keeps its measles. The duty officer, after speaking with the calling station, switches the / 7 switch to pin 10 in the P position (operation). This connects the line to the working plug Rsh. Rn is stuck in the working position of the RG, connected to some p | i6pch m place. When Am is inserted into Grezdo RG, the contact is closed. 5. The lower spring of the socket Pi is isolated from the plug Rsh. By inserting the pin Рш into the nest / V, connects the klopfer station located on the periphery with the klopferam of the workplace of the central telegraph. The work proceeds as follows: plus D, Km, (or K), Cl, .R, L, Gl, Og, upper spring, Osh, / 7, contact / f, Rsh, RG, upper spring P Kl-kloffer workplace . Km and minus batteries.

The key of the work site is shunted, the 4To6i linear relay did not turn on the ringing relay BP and lamp 5 when it was working. When the telegrapher finishes working with the calling station, he must report STOiij to the person on duty at the hub. For etrgo, he presses; the button K presses for a few seconds; 1 6th of the clock is normally open. This turns the OM breaker on. The shutdown relay works and there is no measles. .Left measles will turn on the bouncing light bulb OL.

The chain is set: plus B, pin 6, measles, bounce lamp OL, pin 8 RG and minus B, Right measles will block the relay and it will work all the time.

The duty officer, upon seeing the lamp burnt off on the L lamp, will take out the work and questionnaire plugs Put and Osh from the sockets of the RG and OG 1n switch // switch from the P position (work) to the O position (polling). X This is a plug Rsh from the RG socket, the person on duty will open contact 8 and thereby interrupt the circuit 9. Breakdown of the lamp OL has gone out. In the interrogation socket, Og is closed toTbi Tbi / and 2. The LR relay is switched on into the ground and the Hub is again ready to call over the wire.

Tredmet of the invention.
