The present invention relates to the Gray's writing telegraph known in a number of embodiments from German patents 49275, 69964, 73520, 83999 ^{and 84000.}

The improvement of the telex system consists in the fact that the movement the receiver spring in the receiver in the "long-distance line sent current surges into which the movements of the transducer spring are implemented, and which depending on the direction of the Movement are positive or negative, creates self-induction in current surges of alternating polarity can be implemented. For the application of the latter there are one integer, of ways; as an example, the application of the Wheatstone's bridge described the basic idea underlying it.

Figures 1 and 2 are. schematic representations of the donor respectively. Recipient.

A is the transmitter spring carried by arms 1, 2. The remote circuit goes from the divided battery Z via wire α, closing spring 3, plate 4 of the main switch 5, wires a ¹ a ² to the pole changer 6 via wire α ³ , current circuit piece 16, interrupter arm 7, wire iz ⁴ , resistor i ?, wire a " ^a to the left-hand long- distance line L L. With the parts in this position, a positive current of low strength flows into the long-distance line. If the writing pad 8 is lowered, the current flows out of the wire α ⁴ via the closing spring 9 with the pole changer and breaker in the same position , Schlufsstück ι ο, carrier 11 of the base 8 and wire a ⁵ in the line: there is a Stromstofs of maximum strength.

If the change in direction of the transmitter spring causes the pole changer to move from the stop 12 to the stop 13, the current flows from the battery half Z ¹ via wire b, connector 14, plate 15 of the main switch, wires b ^l b ' ² , StromschlufsstUck 13, pole changer 6, wire a ^s , Stromschlufsstück 16, interrupter arm 7, wire α ^4, etc., and there is a negative current in the line, the strength of which is determined by the position of the writing surface.

If the interrupter arm changes its position from the closing piece 16 to the resting piece 17, the current flows into the line when the writing surface is lowered via wire c, resistor R ¹ , closing spring 18, closing piece 19, carrier 11 and wire a ^5. If the writing plate is in the raised position, as shown in FIG. 1, the branch just described is interrupted and no current enters the line. The purpose of this measure will be further explained.

The circuits by the right side of the. Device outgoing pipeline RL are:

From battery Z via wire a, key spring 3, plate 4, wire a \ wire rf, power circuit ^{piece 12 1} J pole changer 6 ¹ , wire rf ¹ , power circuit piece 16 ¹ , breaker arm 7 ¹ , wire rf ² and main switch in right line, in which a positive electricity occurs. If, as a result of reversing the direction of movement of the transmitter spring, the pole changer moves from the end piece 12 ¹ to the end piece 13 ¹ , the

Line connection from battery Z ¹ via wire b, closing spring 14, wire b \ wire e, current circuit ^{piece 13 1} J pole changer 6 ¹ , wire d ¹ , current circuit ^{piece 16 1} and wire d ² in. Long-distance line -RL, in which a negative current is now entering . In both cases the current has maximum strength. If the interrupter ^{arm 7 changes:} from the end piece 16 'to the rest piece 17 ¹ J, the current is switched into the line ^{via the resistor -R 2.} . Depending on the position of the current changer. the Stromstofs has one or the other polarity and, since the resistor -R ^{2 is} switched on, minimal strength.

In the receiver of Fig. 2, the left-hand long-distance line divides into two branches in 20; one leads over the non-inductive resistor R ^s , 21, electromagnet F, 22, 'where it reunites with the other branch, which goes from 20 through the coils of the relay J, 23, the non-inductive resistor -R ⁴ to 22; from 22 the line leads through the wires ff ¹ to earth. Between the points 21 'and 23, that is, in a bridge between the two branches, the electromagnet D influencing the escapement device is switched on. The electromagnet F controls the reversing device of the receiving spring.

Each of the four sides of the Wheatstone bridge formed by the two branches and their cross connection offers the same resistance; the non-inductive resistances R ³ i? ⁴ each have a resistance of 50 ohms, as does the relay J, and the coils of the electromagnet F each have a resistance of 25 ohms. If a direct current flows through the above system, it regains its equilibrium a short time after the current connection has been established; An equal current flows through the two branches between 20 and 22, and the electromagnet D remains de-energized. However, the equilibrium condition is disturbed each time the circuit is opened and closed, resulting in the following effects:

When the circuit is closed, as the current in its coils increases in intensity, relay J develops a counter electromotive force equivalent to a resistor connected in path 20, 23; At the same time, the electromagnet F also develops a counter-electromotive force, which is equivalent to switching on a resistor in path 21, 22. Consequently, the greater part of the current at point 20 is via 20, 21, bridge with electromagnet D, 23, 22 after Distracted earth; the electromagnet D attracts its armature with one of its poles.

If the line current is then interrupted, the electromagnets J and F discharge induced currents which have the same polarity as the line current which previously flowed through. The current induced in J runs through path 23, 21, 20, the current induced in F flows through path 21, 22, 23; Both therefore flow in the same direction through the bridge 21, 23, but in the opposite direction to the direction in which the line current previously flowed through the bridge; they cause the electromagnet D to attract its armature 24 with the other pole.

The vibrations of the armature 24 caused in the manner described have the following effect on the escapement electromagnet E: If armature 24 is on the connecting piece 2 5, a current flows from the negative pole of the receiver battery ^ ¹ via wires gg \ armature 24, current connecting piece 25, wire g ' ² , to the left coil of the electromagnet E, wires g ^B g- ⁴ , closing spring 26, disk 27, closing spring 28 and wire g ^s to the positive pole of the battery \\ the armature of the electromagnet E swings to one side. If the armature 24 is at the end piece 29, current flows from the battery ^ ¹ to the armature 24 as before. from here via connector 29, wire / ?, the right coil of the electromagnet E and wire g ⁹ to the positive pole of the battery ^; the armature of the electromagnet E swings to the other side. . .

The reversal of the direction of movement of the receiver spring from the right direction to the left direction and vice versa mediates the electromagnet F: If the current surges sent by the transmitter have the appropriate polarity, the electromagnet F places its armature 30 against the connector 31, and current flows from the battery ^ ¹ via gi, armature 30, end piece 31, wire z ² , electromagnet H, wire g * to the positive pole of the battery ^. The electromagnet H attracts its armature and thereby shifts the reversing clutch into one of the two coupling positions. If the polarity of the current surges sent by the transmitter changes, the armature 30 rests against the resting piece 32; the electromagnet H is de-energized and releases the armature, whereby the coupling is switched to the opposite coupling position.

The lifting and placing of the receiver spring is effected as follows: If the opening and closing of the circuit was mentioned above with reference to the movement of the receiver spring, this should mean a considerable weakening of the current strength. The resistances of the long-distance line on the left are dimensioned in such a way that the current is never completely interrupted when the writing surface is depressed, but that there is always enough current flowing in the line so that the relay J experiences the excitation required to attract the armature. ^:

Claims (3)

The one for excitement. the voltage difference required for the receiver spring influencing the current surges is caused by the resistor R ¹ , which is dimensioned with reference to the transmitter battery Z so that it passes the current required to excite the electromagnet J by attracting its armature. Line. Is running. In Fig. It is assumed to be 75 ohms. If the writing surface is in ... the raised position, the current. alternately completely., interrupted and passed through the larger resistor R , which, with regard to the strength of the battery ZZ ^{1, is} so dimensioned that the current flowing through it does not excite the electromagnet J , but the electromagnets E and F , which attract their armatures . The armature of the electromagnet J is therefore always on the rest piece when the writing surface is raised, but always on the work piece when the writing surface is lowered. _| The armature 33 of the relay / influences the device that lifts the receiver spring as follows: If armature 33 is on work piece 34, an electric circuit runs from battery ^ ¹ via wires kk ¹ , armature 33, current circuit ^{piece 34, wire A-2} , the lifting electromagnet K, wire k ^a , wire g * after the positive pole of the battery ^, and the receiver spring is pulled down against the resistance of the spring 35 into the low or working position, ie placed on the writing surface. If the armature 33 is on the rest piece, the circuit of K is open and the spring 35 keeps the receiver spring lifted from the writing plate, ie in the raised or rest position. The paper shift is accomplished by the encoder in the following way: The right-hand remote circuit is never completely opened, but alternately via the interrupter arm 7 ¹ without resistance, and via the resistor i? ^{2 is} closed, which is so dimensioned with respect to the transmitter batteries that the voltage difference caused by its activation is sufficient to generate the current surges that excite the electromagnet D ¹ to control the writing movements of the receiver pen, while at the same time, when the main switch is in the position of Fig. 1, so strong a current flows through the line that the electromagnet J ¹ attracts its armature. If the paper is to be moved, the main switch is placed on the closing plates 36 (FIG. 1); now the current to the line is completely interrupted and electromagnet J ¹ releases the armature 37. Two circuits are provided for the electromagnet M causing the paper displacement: namely from the positive pole of the battery ^ via wire g ⁵ , slip spring 28, metal disk 27 on the one hand via closing spring 42, wire, m, connecting piece 41, armature 37 of J ¹ , wire m ¹ , Coils of electromagnet M, spring of armature 40, spring 39, socket piece 38 and wire ot ' ² to the negative pole of the battery · ^ ¹ ; on the other hand via ^{slip spring 26, wires m 3} m ⁴ , connecting piece 43, connection. ker 37, wire m ¹ and further as above after the negative pole of ^ ¹ .
The disk 27 driven by the paper winding roller is covered with a number of non-conductive blocks or plates lying on a circle in such a way that when the disk 27 is rotated, they move one after the other and alternately under the sliding springs 42 and 26, but without any influence on the contact the disk 27 remain through the slide spring 28, which rests within the circle of the insulating plate. The circuit via the electromagnet M is interrupted during the normal writing position of the instrument, in which the armature 37 lies on the closing piece 41, as a result of the sliding spring 42 resting on one of the insulating blocks. If the main switch 5 is now set in the transmitter to open the remote circuits, then the electromagnet J ¹ releases its armature, the circuit of the electromagnet M is closed via the slip spring 26 and the roll of paper starts to rotate, which continues until the circuit as a result The spring 26 is lifted by the disk 27 rotating with the paper take-up roll through one of its non-conductive blocks. If the writing position is restored by resetting the switch, the armature attraction of the electromagnet J ¹ caused by this closes the circuit of the electromagnet M again, but via a slide spring 42; as a result of this, the paper is displaced until spring 42 is lifted off the disk 27 by a non-conductive block. The rotation of the paper take-up roller in two steps moves the paper by the line width. As already pointed out, the invention is not limited to the one described on the Principle of Wheats Tones see bridge-based embodiment limited; just as little it is connected to the described devices for moving the receiver spring, for moving the paper, as well as for reversing the Receiver, spring or other details related to type and mode of operation.

Embodiment according to claim ι and 2, characterized in that the placing and lifting of the receiver spring by the means of a long-distance line and the electromagnet (J) excited electromagnet (K) takes place in such a way that the interrupter (7) of the encoder at When the writing surface is pressed down (8), the remote current is never completely interrupted, but changes depending on the setting between two currents to which the electromagnet (J) still responds, while when the writing surface is raised, the interrupter switches the remote current between one of the electromagnets (J) non-influencing value and zero changed, so that the electromagnet (J) only at. Rising up the writing plate interrupts the electric circuit of the electromagnet (K) and lifts the receiver spring. ; Embodiment according to claim 1 and 2, characterized in that the paper shift in the receiver takes place by means of the right-hand long-distance line in such a way that the interrupter (7 ¹ ) of the transmitter never completely interrupts the latter, but gives it different strengths depending on the setting, so that the electromagnet (J ¹ ) always attracts its armature and keeps the circuit of the electromagnet (M) open and is only switched off by setting the main switch of the transmitter to the rest position, whereupon the paper shift with the aid of a switch (27) and the slide springs (42, 28, 26) takes place in two paragraphs in such a way that (J ¹ ) opens the circuit of the electromagnet (M) for the first time by letting go of its armature and then a second time when the main switch is switched to the working position by attraction of the armature Time asleep, * whereby each such key is opened by the fact that the switch disk (27) connected to the roll of paper with a nic The conductive part comes under one of the sliding springs (26, 42). 1 sheet of drawings.
