SU6779A1 - Device for automatic start-up and stopping of mechanisms in a direct-printing telegraph apparatus, driven by an electric motor - Google Patents

Description

Normally, stand-alone devices are driven by an a-icHTpiniccKiiM motor; in the absence of the device is worth In order to be able to use the apparatus at the corresponding station, it is necessary to have such a device that it closes the motor circuit at the receiving station from the transfer station. The proposed arrangement is intended for automatic launching and stopping of mechanisms in a direct-printing telegraph apparatus, driven by an electromotive motor. ;

Pa figs. 1 of the drawing of the image layout apparatus and PA circuit of FIG. 2 and 3 - the proposed device.

It is known that at the moment of the absence of work on both devices (Fig. 1) the ratchet couplings are disengaged. In order to make any sending to the second station, it is necessary to couple the transmitter coupling; after it has been coupled and the unit is moving, signals may be peeled in a line. Clutch

the couplings need, therefore, not to be made from the keyboard. It may . be performed by switching on in series with the launching link 14 in the circuit of the apparatus of the simple bursting button 1 (Fig. 1). In order to start the motor, press this button 1 and thereby break the circuit in both starting electromagnets (although both devices are worth). Thanks to this, the electromagnet 2 will work and close contact 3, B1cly connected in series to the motor circuit. Since the regulator is at this moment in a polishing station, the icoiixaKT 4 is closed, and the motor, due to the closure of contact 3, will quickly go simultaneously to both stations and immediately put the devices on cttM i

but, due to inertia itself, it will not stop: At the same time, the closure of contact 2 can be adapted either to the electromagnet itself or to any part of the apparatus that shifts when the signal is sent forward and remains in this position until the end of the revolution. After starting the motor

It is POSSIBLE, by pushing any key, to already send a sign, since the leading ratchet clutches are in rotation. For "stop, t.-s. when attracted to the corona by the electromagnet 2, contact 3 is repropped, on the motor, on the expense (the entire market is stopped, if this signal is sent via the next signal. Bciiicait; ke sending a signal, while the eHje motor has not stopped, the motor will work half a second

the course. At the same time, the regulator always maintains an equal-speed and constant rotation.

In the proposed device a three-arm arm is used: one of it. shoulder And freely c tano with a crust of 9 starting electromagnet 2; the other is his shoulder 8, in order to start up the electric motor when the circuit is open

electromagnet 2, is located against the contact 3, including the engine;

the third shoulder 10 is provided with a process, which falls into the recess 7 of the washer 6, pas on the axis of the rotationally driven mechanism. To cope with these couplings, with 9

- one arm of the lever 12 is engaged, the other arm of which is assigned to be inserted into the groove 5 of the coupling, invariably

- associated with a rotatable mechanism. For disengagement of the couplings, 1; flap 13, adjacent to groove 5, is used. In the steady stop pin, neither the end of the three-arm lever 8 enters the recess 7 and, under the action of the right

contact spring 3. opens contact. The descent of the core 9 leads the end 10 of the lever 8 out of the recess 7, due to the impact of the shoulder 11, and the shoulder 8 closes the contact 3. At the same time, the axis comes into rotation; the end of the three-shoulder arm, come out. trough 7, slides along, the circumference of the washer 6; by virtue of this, contact 3 remains closed until that time 2 -

until a complete revolution is reached and the shoulder 10 does not fall back into the cavity 7. The next departure of the core will perform the same action.

The subject of the patent.
