BRUNO KRAUSZE in SOLINGEN.

Patented in the German Empire on October 14, 1906.

The invention aims to operate and control clocks through the power sources on the telephone exchanges using rder Ferrissprechleituhgen with the. normal telephone service circuit. ■■ ·. ' . The same differs from the previously known devices essentially in that specially switched power sources both at the subscriber as well as on

ίο the office as well as devices in the. such as relays, interruption points that are not required for telephone service, can be completely avoided so that the security of the telephone operation is not in the is at least disturbed.

With the older facilities one could

only setting the participant's clocks

. Reach the correct time while the winding up was taking place by local power sources, their Condition was not to be supervised from the central office.

According to the present invention, however, one is able to the clocks from both the Central from pulling up as well as discontinuing.

This is achieved in that the device for winding the participant's watch or setting the DC block on the subscriber station for the correct time (Capacitor, polarization cells) bridged and thus electricity from the central battery removes.

In Fig. Ι the essential components of a telephone device with a central battery are shown schematically. If the remote receiver 3, as shown, is removed from the switch hook 1 at the subscriber station, so. Hook 1 closes the lower contact and thereby switches the telephone 3 and the microphone M on . The battery 4, which is connected to the two busbars 5 and 6, now sends a current from the -f- pole through subscriber line 7 via microphone M, contact 2, switch hook 1, subscriber line 8, winding from call relay 9 to rail 6 (- pole of the battery 4): The call relay 9 attracts its armature 10, which switches on the call lamp 11. The desired connection is established and runs via the pawls 12 and 13.

When the conversation is over, the remote receiver 3 is hung on the switch hook 1, as a result, the same closes the contact 14 and switches the alarm clock 15 on. In row With the alarm clock 15 there is a direct current block 16, consisting of a capacitor or a polarization cell, which prevents the battery 4 current through the alarm clock 15, which only responds to alternating current, sends. The subscriber line is currentless. If one closes one on either side of 16 with any electric lift device provided clock 17, then the clock gets its operating current from the battery 4 remove, namely via the following route: from + P ° l of the battery 4 via the subscriber line 7 through clock 17 via contact 14 to switch hook 1, subscriber line 8, relay 9 to busbar 6 or w. - Pole of the battery 4. Turn on the clock 17, as shown in Fig. 1, exclusively parallel to the alarm clock 15 and the DC block 16 contained line

, branch in the subscriber set, the clock is through the hook switch during a call I switched off and can go through. a possible activation of your elevator winding do not disturb the conversation.

The driving force of the clock can take care of all possible disturbances from the telephone service averted for a longer running time (for example for a day) during the night, in whichever the telephone service is suspended, to be renewed.

An example of this is given in FIG. 2 and, at the same time, an adjusting device for the consumer watches are shown, for example.

The hour wheel 29 rotates a wheel 30 once every 24 hours; touched the same (z. B. before 3 o'clock at night) with its contact pin the contact spring 32. The wheel 30 is conductively connected to the minute hand 31; shortly before 3 o'clock the minute hand 31 touches its contact spring 33. This the following current connection is established: from the + busbar 5 via line 8 after switching hook 1, alarm clock contact 14, line 34, brushes 27, motor armature 25, brush 28, Contact spring 33, pointer 31, wheel 30, contact spring 32, line 35 and 7 to the busbar 6. The motor is therefore switched on and winds the clock by means of the wheel 26. A branch line goes from the line 34 to the contact spring 33 via the relay 36, which is therefore switched on simultaneously with the motor 24 and a Lever 37 is tightening. The same closes with one end the auxiliary contact 38 parallel to the contact 33, while the other end is in the path of the pointer 31.

When the pointer 31 has left the contact spring 33, the auxiliary contact remains 38 both the motor 24 and the locking lever 37 switched on; the pointer 31 because the clock has a small advance, pushes against the locking lever before the set time has elapsed 37 and is held until the power is cut off at the office. The relay 36 then releases the lever 37 and his left arm goes out of the path of the pointer under the influence of the spring 39 31 out; the clock goes on correctly adjusted. ■

■ Switching off at the office can either be done by a simple switch 40 (Fig. 1) done by hand or automatically by a standard clock 41, which, as schematically shown, through the pointer 42 and contact 43, the relay 44 turns on. The latter attracts the armature connected to the switch 45 and thereby switches the. battery from the busbar 5.

It should also be mentioned that instead of the elevator devices and relays described all motors rotating or oscillating by working current can be used

Claims (2)

Patent Claims: ι. Switching of electrical clocks in connection with telephone networks, characterized in that that the subscriber's clocks are placed in parallel with the direct current blocks (e.g. capacitors 16) of the telephone and bridge the same when the clocks need electricity. 2. Circuit according to claim 1, characterized in that the parallel circuit for direct current block in the alarm branch of the subscriber station (14, 15) takes place, for Purpose, the clock during a call through the hook switch on the voice line switch off. 1 'sheet of drawings.
