Description

Electric cipher machine with writing device. They are electric Cipher machines known in which a writing device in the cipher machine is arranged by which when handling the cipher machine, for. B. the individual Keys of such, depending on the position of the encryption device and the associated Switch the cipher that is written down in decipher or plain text.

There is also known a type of cipher device in which an encryption device is electrically connected to two typewriters, in the way that the one typewriter to operate the whole cipher device, So as a transmission typewriter, is used, namely writes down plain text and the flow of electricity through the encryption device, while the other typewriter only as The recipient is used, namely writing down the cipher or decipher.

On the other hand, encryption devices are known which do not have a possibility offer the cipher or decipher automatically in writing when handling the device specify where the cipher or decipher is optically, z. B. by Lighting of incandescent lamps, or otherwise indicated and by hand or specially written down on a typewriter.

The disadvantage of the above-described cipher machine with two writing devices is that the required typewriters special writing devices must be, of which a writing device with appropriate contacts and the other writing device with respective magnets or a motor and must be equipped with a character wheel. Such a facility is therefore in the spatial expansion relatively large, heavy, difficult to transport and expensive, of course, while encryption devices have the disadvantage that the cipher or decipher is not specified in writing and by wrong Reading errors can arise from the device so from the skill and the The operator's attention is highly dependent.

These disadvantages are overcome by the invention, and it is given the possibility of an existing, ratio m i I AESS - to use simple and inexpensive encryption device for producing a cipher written or Dechiffrats. This is done according to the invention in that an electrical cipher machine containing a writing device and another non-writing cipher device are electrically coupled and provided with switches and connecting lines which switch off the cipher device of the writing cipher machine and the writing device of this cipher machine when operating the cipher device coupled to it, the writing of the cipher or Have the decipher carried out.

One advantage of the subject matter of the invention is z. B. is that now the owner of a writing electric cipher machine - with a particularly high quality Encryption device this through the coupling with the encryption device to the traffic with substations that only use the cipher device with a less complicated cipher system own, can use.

The invention is illustrated in the accompanying drawings, for example, and it shows: FIG. i a diagrammatic representation of the subject matter of the invention, FIG. 2 is a circuit diagram of the object of FIG. 1, FIG. 3 is a highly schematic one Circuit diagram of the subject matter of the invention in a slightly different embodiment in the position for encryption and plain text, Fig. q. the schematic for the item 3 in the position deciphering and plain text.

In Figs. I and 2, i denotes an electric cipher machine with writing device 2; 3 is a simple encryption device, in this embodiment a non-writing encryption device, which z. B. by pressing the q key. one Encryption device 5 triggers and the cipher in openings 6 optically displays. In the case of the writing cipher machine i, the cipher device is at 7 and at 8 the keyboard for operating the cipher machine is indicated. o shows the sheet of paper, on which the cipher or decipher is written. Io has a Lever to see by means of which the cipher machine either to cipher or Plain text or deciphering can be set.

According to the invention, the encryption machine i with the encryption device 3 electrical, in the illustrated embodiment by a cable i i with plugs 12 and 13 releasably connected. The cable consists of as many wires as the symbols of the encryption device, e.g. B. it is 28-core. The plugs are accordingly Equipped with as many contacts.

There is also a switch 1q on the cipher machine i. appropriate, which can be set in two positions, small machine - big machine can and switches off the encryption device 7 when it is placed on a small machine. Such encryption machines are expediently equipped with a double switch 15, which with each keystroke by one of the type magnets 16 of the writing device .2 is closed. This once a magnet 17 for the carriage and at the same time a magnet 18 for the automatic change of the encryption device 7 made to respond. In the circuit diagram of FIG. 2, a denotes the position of switch 1q. on small machine, b the position of the switch on large machine. From this circuit diagram it can be seen without further ado that in position a, that is, if the cipher machine i is electrically coupled to the cipher device 3 and the switch is set correctly, the current curve in the circuit of the magnet 17 for the Paper carriage circuit is not changed, but the power line to the magnet 18 interrupted for the automatic change of the encryption device 7 at i9 is. In this way, when you press a key q. of the encryption device 3 triggers the encryption device 5 of this device, but not the encryption device 7 of the cipher machine, but only its writing device 2.

The setup in such encryption machines is such that when the two magnets 17 and 18 respond, the armature of these magnets is locked and thereby a contact 2o or 21 is interrupted in their line, so that the Magnets are de-energized. To unlock the armature of these magnets are now more Magnets 22 and 23, so-called end magnets, are provided and placed in a special circuit 24 switched on. In the circuit 24 of the magnets 22 and 23 there are others Contacts 25, 26. These contacts are closed when the magnets 17 and 18 are excited and remain closed until magnets 22 and 23 have responded. The latter occurs when a pressed key q. or 8 is released. In the Line 2q. a special contact 27 is provided according to the invention, namely is this contact spatially in the cipher device 3 in connection with the keys q. appropriate. In the illustrated embodiment, this contact is an opening contact formed and makes the magnet 22 currentless, i. H. prevents a Q button. a current flow in the line 24 until the relevant key 4. is released and goes back to its starting position. Now is that Contact 25 coupled to the magnet 22 so that when the magnet 22 responds briefly then the contact 25 is opened and the magnet 22 is de-energized again as a result will.

The current curve when a key of the encryption device 3 is pressed as follows: i. Circuit -j-, switch i4 (position a), line 28, button .t, line 29, in one direction through the encryption device 5, in the other direction back, line 30, line 31, plug 12, cable i i, plug 13, line 32, type magnet 16 ', line 33, contact 20, line 34., -.

2. Circuit When the type magnet 16 'responds, the Double contact 15 'closed, so that the following current flow comes about: -E-, line 35, closed contact 15 ', line 36, magnet for the paper carriage circuit 17, closed contact 20, line 34, -.

The magnet 17 prepares the indexing of the paper carriage Writing device 2 in front, and this switching occurs after the type has been struck or after releasing a previously pressed key.

When the magnet 17 responds, the contact 2o is opened, so that the magnet 17 is de-energized. Its anchor is through in the tightened position the magnet 22 locked.

At the same time, contact 25 has been closed.

3. Circuit If the pressed key d. is released and in when it returns to its original position, the contact that was open up to that point is thereby opened 27 closed, and the current curve is as follows: -3 -, switch 14 (position a), line 24, contact 27, magnet 22, closed contact 25, line 34., -.

The magnet 22 responds, unlocks the armature of the magnet 17, and the cipher is again ready to write for the next character.

In Figs. 3 and q. the current flow is illustrated when two Encryption machines are coupled together with writing devices. In the drawings 37 indicates the cipher device of one cipher machine, 38 the cipher device the other cipher machine. 39 is a key of the one encryption device, which is to serve as a Gebechiffriermaschine. q0, 44 42 and 43 are each a multi-part, z. B. 26-part switch. The switches can be in positions c, d and e where c is the encryption position, d the decryption position and e mean the plain text. .4: f is the electrical connection cable which couples the two encryption machines together. With .I5 and 46 there is one type magnet each illustrated. Fig. 3 illustrates the position of the individual parts for the encryption position, the cipher device 37 being set to cipher and operating, while the cipher 38 is turned off. The encryption machine of the Encryption device 38 accordingly writes plain text when a key 39 is pressed, while at the same time on the cipher machine of the cipher device 37 the cipher is written down. In Fig. Q. is the corresponding position for deciphering shown.

The arrangement according to FIGS. 3 and 4 has the advantage that at the same time with the writing of the cipher the plain text is determined and accordingly after preparation of the cipher can be controlled. When deciphering, is simultaneously with The cipher is written down in the writing of the decipher and can accordingly be checked after the decryption has been written.

In all embodiments there is also the advantage that that the ciphering or deciphering person does not use the cipher or decipher to see because the cipher machine with the writing device on one Place inaccessible to the operator of the other device so that the messages to be kept secret are only available to special persons Knowledge.
