Dictation machine system. Patented in the German Empire on March 1, 1921.

Until now, dictation was played by means of

a dictation machine (e.g. a telegraphone) and recording the call from the dictation machine by eavesdropping in such a way that the dictator uses his machine discussed in the work room (office room) and that thereupon the discussed roller, tape ο. Like. From the typist writing the dictation either on the same or was tapped on a special device. At large bureaus with many Such a dictation machine is very cumbersome and expensive, and it also uses the available ones Facilities are very inadequate, as the individual machines are only needed temporarily, i.e. they are usually at a standstill.

The object of the invention is a device for row-by-row recording and listening of dictations by means of dictation machines in that all dictation

machines are grouped together locally for joint maintenance and joint operation while the dictation stations located at any location are controlled by a control center be connected to one of the free dictation machines. This arrangement enables full utilization of the machines to be achieved at the same time Simplification of maintenance and handling, furthermore, becomes important to operating personnel saved up. In the drawing, the subject matter of the invention is illustrated, for example, namely Fig. Ι shows an overview diagram of the device, Fig. 2 shows a circuit diagram for a dictation and listening station. According to Fig. 1, transmission lines 4 run from the machine room 1 from the dictation machines 1, 3 to a switchboard 5, which is divided into individual switch panels a, b, c, etc., each field in turn being divided into subfields, namely a dictation station, recording station and typing station , is divided. The dictation passages a ', b', c ', df, e'. are connected to the control panel through transmission lines 6, the writing points a ", b", c ", d", e " through transmission lines 7 in such a way that each telegraphone independently of the others with a free dictation or a free listening point through the can be panel guards, respectively. the schematic of a circuit is illustrated in FIG. 2. in this case, D ¹ is a Diktierstelle and S ¹ is a listening position is. desired by the Bureau D ¹ of a dictation to be abandoned, the dictating person presses the call button and picks up the receiver 12. The call arrives at the control center (switchboard 5, Fig. 1) with simultaneous display on the display field belonging to D ^1. The connection is now made with a free dictation machine. Pressing a button »Forward« activates the forward relay 51 (Fig. 2) switched on and thereby a circuit via the contact 52, slip rings with brushes 58 and the coils of the magnets 31 closed, whereby the coupling with the Ab slave disk 33 takes place, ie the drive of the telegraphone. The contact 52 remains closed by the locking lever 56 until the same is triggered by the "stop" relay. The shaft 35 which passes through all the telephone sets is continuously and uniformly driven by the motor 34. The telephone line or telephone wire 36 moves when the call is recorded in the direction of the arrow shown in FIG. 2 and is wound or unwound on reel wheels. The speech currents reach the magnet 37 via the plug contact 26 and cause the dictation to be recorded. By pressing the “Halt” button, on the other hand, the “Halt” relay 55 is actuated and the locking lever 5 6 is pulled up, ie the contact 52 is interrupted, so that the magnets 31 are de-energized. A reverse relay 53 is also provided for checking what has been said by listening in on the dictation station, through which contact 54, slip rings with brushes 59 and the coils of magnets 39 are closed. The stopping can take place again by the stop button, through which the contact 54 is guided by the release of the locking lever 57 by means of the stop relay 55. The circuit for listening to a recorded dictation from a listening point S ¹ takes place in that the control center establishes the connection between a listening point and a dictation machine being discussed. The operator of the typing station then presses the "ForwardSÄ" button, whereupon the dictation machine starts moving again and forwards the recorded dictation to the listening station, from which it can be transferred to the typewriter. The hearing circuit is closed by the coils of the magnet 37 via contact plugs 26 and earphone 42. The shutdown can take place at any time by means of a stop button and the corresponding stop relay 55. Ρλτεν τ-An Proverbs: i. Dictation machine system, characterized in that a number of centrally powered dictation machines that can be coupled to the drive independently of each other are connected to an exchange to which on the one hand any Number of dictation sites, on the other hand any number of writing sitesi closed in this way are that each of the existing dictation passages and each of the existing writing passages are independent of one another and regardless of the number of dictation and writing positions by switching with each the existing dictation machines can be connected. 2. dictation machine system according to claim i, characterized in that the independent switching of the dictation machines (for example telegraphones) from one another takes place by means of a constantly rotating common shaft, with which each individual dictation machine through one for itself switchable electromagnetic clutch is in connection.
