PATENT SCRIPT

CLASS 21: Electrical apparatus.

The invention relates to the type of telegraph in which the device for writing down the message to be sent at the sending station causes the handwriting to be recreated at the receiving station by interpreting the writing as the result of two components that act at right angles to one another, as well as the mathematical theorem has been applied: that any point on a curve is determined by its distance from two coordinate axes intersecting at right angles, and accordingly two electrical currents are simultaneously sent to the receiving point by every movement of the sending stylus (pen or spring) to there respectively. to act as a horizontal and a vertical driving component on the rewriting stylus, so that its movement emerges as a resultant of these two drives. A writing telegraph of this type is described in patent specification No. 49275, in which the sending stylus (A -spring) generates the two drives in such a way that it actuates two circuit breakers at the same time to divide two currents that are constant in strength but pulsating to send power machines acting on the receiving pen (G-spring) from opposite sides, and that a pole changer is connected to each circuit breaker in order to reverse the driving direction of the power machine every time by reversing the polarity of the current pulsations when the ^ 4 -spring is reversed Direction of movement the circuit breaker moves in the opposite direction. . ■. '

The present invention is based on a similar ^ - borrowed ideas, but with the essential difference that they are more rapid and more sure, each breaker sends two types of currents at the same time, viz a pulsating current that changes polarity with each pulsation, depending on the direction of the drive represented by the respective breaker is positive or negative, and that these latter currents are now used to make the G-spring to couple with the prime mover and reverse the direction of attack while the pulsating currents influence the movement drives communicated by the G-spring through inhibitions, so that the movement is only intermittent and precisely according to the measure of the movement the Ä spring can perform. Otherwise are also the same facilities as in the older Gray writing telegraph mentioned met.

As in the case of the writing telegraph described in patent specification No. 49275, in the transmitting instrument (Fig. 1 to 8, 13 and 13 a) run from the tip of the pen A or A nib (handle equipped for writing, Fountain pen, pencil) cords 63, 64 after rollers 65, which give movement to the brushes 73 of the jet disk circuit breakers B and C , with the winding of springs 70. The roller is supported by its spindle in a thrust bearing 69 at the top and by an angle arm 67 hanging down to the side at the bottom on the bearing point 68. In the axis of the spindle 66, the arm 72 of the sliding brush 73 is mounted by means of the spindle 71 between the roller and the arm 67, and the roller takes the brush around with it, depending on its direction of movement, by means of one or the other driver 74, 75, so that the brush pauses at every reversal of movement. From each interrupter leads BEZW after the receiving point. b and c each via two batteries Z respectively. Z ¹ on the sending point and \ respectively. \ ^λ on the receiving point (Fig. 13). The two batteries of each line face each other with the same poles and are also those ZZ ¹ stronger (most expediently by three times) than \\ ^λ . The connection of the interrupter with Z (Z ¹ ) is effected in such a way that the line b (c) divides into two branches in front of it; the one b ^l (c ¹ ) goes through Z (Z ¹ ) into the earth, the other b ' ² (c ² ) after the metal body of the radiation disc 89, while the brush through a line b ^s (c ^z ) also to the Earth is closed. As a result, every time the brush stands on a conductive beam, the battery Z (Z ¹ ) is switched off and only the battery ^{1 is} switched on, so that it determines the polarity of the pulsation, while when the brush comes into contact with one Both batteries are switched on in the non-conducting beam, the current of the weaker ^ ^ ^{1 being} neutralized, so that the current of the stronger battery now determines the polarity of the pulsation. As the latter current has three times the strength of the former, the same current strength is always effective, but with constantly changing polarity, the number and speed of the succession of these pulsations depending on the length of the path and the speed of the brush.

On each interrupter spindle 66 sits an arm 86 held by friction, from whose conductive tip a line d respectively. e leads to the receiver and which depending on the spindle rotation against one or the other fixed Stromschlufsstück 87 and 88 respectively. 87! and 88 ^{1 is} applied. Pieces 87, 88 are connected to opposite poles of two earthed batteries gg ¹ , as are pieces 87 ¹ , 88 ¹ with batteries // ¹ . If the j4 spring moves away from the interrupter B , arm 86 rests on the end piece 87 and flows —current from g through d into the receiver, and vice versa -f- current from g · ¹ , if by reversing the direction of movement of arm 86 against the end piece 88 is placed, and also with respect to the breaker C and the batteries ff ¹ .

To telegraph you take the yi pen in your hand and use it to write on the pad 117 as you would with ordinary writing. As often as the spring is moved downwards with respect to one of the breakers, the cord winds or. 63, 64 from the roller 65 and thereby grinds the brush 73 in the corresponding direction over the radiation disk 89 and thereby causes the sending of a succession of current pulsations of alternating polarity into the circuit respectively. b c; If the spring is then moved upwards with respect to this interrupter, the spring 70 rotates the brush in the opposite direction over the jet disk with the winding of the cord with the same effect. At the same time, as long as the spring is from the breaker B respectively. C moved away, the arm 86 at 87, respectively. 87 ^{1 are} present, so that the line d respectively. e - receives electricity; then moves the spring respectively on the breaker B. C to, so the arm 86 is against. 88 resp. 88 ^x placed and thereby -f- current in line d respectively. e sent. As a result of the described drive of the brush by the drivers 74, 75, whose. Distance is slightly greater than the deflection of the arm 86, it pauses at each reversal of the direction of rotation of the spindle 66 on the relevant conductive or non-conductive beam in order to allow the time necessary to change the drive in the receiver.

With regard to the receiver, the receiving spring G or G -spring (which is intended as a fountain pen as in the patent specification mentioned) is attached to the hinge point of two arms 21,22 extending at right angles from one another (e.g. made of thin metal tubes), which each go through a cord 93 attached to both ends under tight tension are coupled to a rotatable pulley 94 in such a way that the cord is looped once around the latter. To ensure accurate reproduction, the arrangement is such that the distance between the G-spring and the point at which the cord crosses on the reel is always the same as the unwound length of the cord 63 or at the same time. 64 of the ^ 4 spring, so that both springs move in unison.

The rollers 94 are now driven as follows with the aid of the currents sent through the lines de under the influence of the current pulsations sent over the line bc. Since the device in question is the same for each role, only one, namely the one for the left-hand role, will be described. A spindle 30 (FIG. 14), which is connected to the shaft 96 of a prime mover 95 by means of countershafts, is loosely inserted through two cord disks made of soft iron 28, 29 and an electromagnet is respectively on it in front of each of the latter. X ¹ Y ¹ attached. (The spindle 30 is common to both devices and the corresponding electromagnets for the right-hand roller 94 are labeled XY .) The head disk of the electromagnet winding facing the cord disk is non-conductive, while the other (outer) head disk and the jacket are made of soft iron. The jacket as well as the core protrude so far over the inner head disk that they with the disk respectively. 28, 29 are in contact. The latter form the armature for the two electromagnets .. To prevent sticking when demagnetizing, the armature disks are expediently covered with a non-conductor, such as parchment z. B., occupied. If one or the other electromagnet is broken, the armature disk is coupled to the spindle 30. To each of these is by means of a cord respectively. 9, 9 ¹ a weight respectively. M ¹ and JV ¹ appended. Each of these consists according to Fig. 1 2 of an electromagnet,-whose core 11 with the jacket 10 enclosing the coil at one end by a soft iron disk 12, at the other end and in the middle, however, by non-magnetic (brass or hard rubber) disks respectively . 13, 14 is connected. A non-magnetic rod 15 is loosely inserted through a corresponding hole in the core, on which a soft iron disk 16 (very expediently adjustable) sits in front of the disk 14. A cord 8 is pulled through a narrow hole 18 drilled through the middle disk 13, the jacket ι ο and the core 11, from a disk 39 connected to the roller 94 around the guide roller ^{40, through the electromagnets .M}} and N ¹ (below which a roller 41 is suspended to keep it taut, the bearing 37 of which is guided on rods 33, 35), · a second guide roller 40 runs back towards the disk 39. The roller 94 is connected to the latter by a sleeve 48, which roller 94 is connected by a tooth coupling 47 to the stationary spindle 46 of a climbing gear 25 (inserted through the pieces 94, 48 and 39). The (expediently adjustable) jamming tabs 105 working together with this (which have the same angle as the helical gear teeth, so that the escapement can be used in both directions) sit on the armature 99 of a polarized relay H ¹ (on the right-hand side H), the coils of which are in Circuits c (or b with respect to H) lie.

The electromagnets M ¹ JV ¹ (or MN) and X ¹ Y ¹ (or XY) are related to the circuit e (or d) as follows (FIGS. 13a and 14). In the circuit e (d) a polarized relay J ¹ (J) is switched on,

whose armature is connected to one pole of a battery Ö ' (O) and plays between two connecting pieces 19 and 20. From 20, a line goes through wire m, coil of M ¹ , wire with closing spring 51, sleeve 5p ¹ on spindle 30, coil of Υ ^λ , spindle 30, spring 24 and wire ο to the other pole of the battery O '. From 19 a line leads through wire n, coil of N ¹ , wire η \ wrench spring 53, sleeve 31, winding of X ¹ and spindle 30 to wrench spring 24. From wire m ^1, a short circuit is around through wire m ² F ¹ around after the return line ο; out, and also from wire n ¹ through wire n ² a short circuit around X ¹ to 0; in both short circuits are usually in the open position. located breakers 55, 56, which are arranged in the path of the electromagnets M ¹ N ¹ . If the A spring is moved, for example, in the direction of arrow 2 (FIG. 14), ie away from the interrupter C, current flows from the battery / current through e, the electromagnet J ¹ has placed the armature 52 against the connector 19 and it flows out the battery O ¹ current through the coils of ΛΓ ¹ and X ¹ , while M ¹ and Y ^{1 are} off. N ¹ sucks in the rod 15, so that it moves its hole against the holes in the core and pinches the cord 8, on which the weight of the electromagnet N ¹ now pulls and the disk 39 respectively. Roller 94 gives rotary drive in the direction opposite to arrow 3 (Fig. 14). At the same time, electromagnet .X " ¹ has also coupled it to the spindle 30 by tightening its armature 29, so that the electromagnet M ¹ is wound up by winding the cord 9. N ¹ continues to sink and M ¹ to rise until it is reversed the A- spring and folding the arm 86 against Schlufsstück 88 ^x -j- current is sent from f ^l through e by now the Elektromagnet./ ¹ flips its armature 52 against Schlufsstück 20, whereby now the current of the battery O ¹ in the Circuit n, i.e. directed by the electromagnets M ¹ and Y ^1. In electromagnet N , the elasticity of the cord 8 pushes the rod 15 with its hole back in front of the holes in the core, so that the electromagnet JV ¹ becomes free ; likewise, the electromagnet ^X] läfst los its armature, the electromagnet ^M1 DAF now can drop the same time, however, solenoid Af ¹ verkuppelt with the line 8, while the solenoid Y ¹ by its attraction, the armature disk 28 to the spindle. 30 couples, with the result that the electromagnet N ¹ is now lifted, while the electromagnet M ¹ sinks and drives the roller 94, in fact now in the opposite direction to the direction of arrow 3.

Since, when reversing in the transmitter, the brush 73 remains on the beam it is currently touching, for longer than the turning of the arm 86 requires, the current in c is not interrupted, the armature 99 of the electromagnet H ¹ remains inserted into the climbing wheel and the roller 94 is prevented from rotating until, after the electromagnet M ¹ N ¹ and X ¹ Y ^{1 have been} properly changed, the opposite driver 74 or 75. comes against the brush, use what the Pulsirungen again and the resulting vibrations of the armature 99 to the .to this time pulling electromagnet M allow ¹ or 2 V ^1, the BEZW · ratchet wheel. to advance the roller 94 only tooth-wise, whereby the associated arm 21 respectively. 22 of the G-spring is moved in corresponding paragraphs. The number of these steps and the speed of their succession correspond to the number and subsequent speed of the pulsations which occur between two current reversals in circuit c (b) , and since these pulsations in turn correspond to the speed and path length of the .Α-spring, the G-spring in accordance with that.

The purpose of the shunts described w ² and n ^{2 is} to prevent that the electromagnets BEZW. M ¹ N ^{1 are} not pulled up too high by the electromagnet in question, e.g. B. N ', then hits against the associated current closer 55 and moves it into the closing position; as a result of this short circuit now loses the electromagnet BEZW. Y ¹ its magnetism and releases its armature disk, as a result of which the electromagnet N ¹ falls again and opens the short circuit again; now electromagnet Y ¹ is excited again and the electromagnet iV ¹ is raised again until the short circuit recovers. In this way, the electromagnet iV ¹ (and also M ¹ ) swings up and down in its upper limit of movement until the current is reversed. enters e (d) .

The electromagnets M ¹ N ¹ (MN) guide themselves in their movements by means of resilient brackets 36 on the rods 33, 34 and 35; buffer springs 38 are arranged around the lower end of the latter in order to protect the electromagnets from damage in the event of a sudden fall.

The circuits d and e are also used to bezw by placing and lifting the ^ 4 spring. of the writing pad 117 to cause the same movements of the G-spring. At the end, the latter rests on a support 130 which is the extension of the common (vertically guided) armature 1 29 of two poles facing each other

arranged electromagnet ^ S and T forms that receive power from a battery y. The circuit of S goes from battery y through wire sts, connector 134, armature 133 of a relay P \ wire s, electromagnet S, wire sts located in circuit e behind the electromagnet J ¹ , back to j ^; the circuit of T goes from battery y through wire stt, connector 128, armature 132 of a relay P, wire i, .electromagnet T, wire 11 s located behind the electromagnet / located in circuit d , back to y. The electromagnet T has the touchdown of the electromagnet S to cause the lifting of the G-spring. At the end, the relays PP ¹ are regulated with respect to the force of the tapping springs of their armatures 132, 133 so that the armatures can only obey the attraction when the full current is flowing through PP ¹ . At the transmitting station are now in the circuits d and e resistors respectively. RR ^{1 is} switched on and the relevant one is switched off at the appropriate time. This is achieved by the writing pad 117 by being carried by a spring-supported, rotatably suspended plate 118 (FIG. 2) which, depending on whether it is in the upper or lower position, closes a short circuit around the resistor R or JR ¹ . If the plate 118 yields under the pressure of the ^ 4 spring, it opens in 120 the short circuit around R ¹ , i.e. H. switches this resistor into circuit e , so that relay P ¹ releases its armature and the circuit is interrupted by S; on the other hand, the plate in 118 creates the short circuit around the resistor R , as a result of which the full current is sent into the circuit d, the relay P attracts its armature and thereby closes the circuit of the electromagnet T , which now pulls the support 132 down by attracting the armature , with the G-spring on the writing pad 117. The spring remains in this position until the end of the graph by lifting the ^ 4-spring removes the pressure on plate 118, whereupon it swings back, opening the short circuit around R and creating the short circuit around R ¹ ; now full current flows through the circuit e to the relay P ¹ , which closes the circuit of the electromagnet S by armature attraction; this pulls the armature 129 and thereby lifts the support 132 and G-spring off the paper. The armature 129, the weight of which, along with that of the support and G-spring, is balanced by a spring 131, is held in the set position by friction springs 43 (FIG. 2). In the modification of FIG. 18, the two electromagnets S and T are arranged side by side, and the common armature 129 is rotatably supported between their poles; the spring support 132 is attached to a lateral extension of the armature. ■

Furthermore, the circuits de also serve to move the paper from the sending point to the receiving point after completing a line or a number of lines or, if otherwise necessary, by energizing an electromagnet V by means of the circuits of the electromagnets S and T which then causes the paper to be removed from its roll. The paper runs from the roller 2 (loosely placed on the axle 7 held in the hangers 5 and coupled to the fixed disk 3) over the friction roller 25 and over the base 117 into the drawing rollers 143, 144.

The electromagnet V (Fig. 13, 13a, 14, 4 and 8) is an electromagnet with consequent poles. It consists of two soft iron rods 135, 136, the ends of which are connected by soft iron shoes 151, 152 and wound under them in a known manner, leaving a middle bare part, from which pole pieces 137, 138 extend beyond the winding, with armature 139 being rotatable opposite is arranged. The winding ν is in the circuit of the electromagnet S and the winding v ¹ in the circuit of the electromagnet T, so that current from the battery y flows through both windings in opposite directions. If only one winding is switched on, the magnetic circuit is closed by the shoe opposite it and none of the pieces 137, 138 are magnetized; if, on the other hand, both windings receive current, the pieces 137, 138 become poles and the armature 139 is attracted. In order to effect the simultaneous armature attraction on the part of the relay PP ¹ , which is necessary for the latter, regardless of the position of the writing pad 117 on the transmitting station, a changeover switch is arranged on this in the circuits de between the resistors RR ¹ and the receiving station, by means of it the said resistances are made around shunts after the batteries g and / '. 3, 6 and 14, this switch consists of a by means of arm 101 and spindle 100 mounted in the table to be rotated block 102 with two pairs of electrical circuit strips 103 and 205, 103 ¹ and 205 ¹ (of which only one pair is visible); On each pair of strips a pair of secondary springs 106, 107 connected to circuit d and secondary springs 106 ¹ , 107 ¹ connected to circuit e drag. Strip 205 is connected by conductor α in connection with the battery g in front of the end piece 87, while 205 \ is connected by wire h to the circuit of the battery f ^{1 in} front of the end piece .88.

is closed. By turning the arm ίο ι to the left, both circuits d and e are opened by 106 and 107, 106 ¹ and 107 ¹ respectively onser contact. with 103 and 103 ¹ guess; immediately thereafter, however, 106 and 106 ^{1 come} to resp. 205 and 205 \ whereby the circuit d around R through a and the circuit e around R ¹ through h ends. The full power of the two batteries g and f ¹ is sent to the relays PP ¹ at the same time, so that they close the two circuits s and t at the same time by attracting an armature and thereby actuate the electromagnet V. (The spring support is not affected, because the effect of the two electromagnets S and T on the armature 129 is balanced.) The armature 13g of the electromagnet V is limited in its vibrations by stops 140, 141. It is provided with a shoulder 142, which cooperate as jamming flaps with two jamming arms 148, 149 (see also FIG. 4a). Spindle 1.55 is connected to the shaft 148 ^{1 of} a weight disc 149 ¹ by means of an intermediate gear 154, 153 (the latter two parts are coupled in a known manner by a ratchet in order to be able to pull up the weight without disturbing the two rollers); Shaft 148 ¹ for its part hangs together with shaft 145 of the upper paper feed roller (which can be displaced vertically in its bearings under spring pressure) by means of intermediate gears 146, 147. The arms 148, 149 are offset from one another so that 148 comes against the shoulder 142 when Armature 139 is at the front stop, whereas 149 meets 142 when 139 is at the rear stop. In both cases, the drive exerted on the disk 149 by the pull of the weight is canceled. Set, 139 is at the back stop. As soon as current flows through both windings of the electromagnet F and thus the armature 139 experiences attraction, the shoulder 142 releases the arm 149, the escapement starts rotating and thus allows the paper to be drawn forward. If the attraction of the armature 139 is only momentary, it falls back onto the rear stop before it is touched by the arm 148, and then inhibits the arm 149 again after one full rotation of the escapement. If, however, the excitation of the electromagnet V lasts long enough, the arm 148 finds the armature 139 in its path and braces itself at its shoulder 142, as a result of which the escapement can only make half a turn. During the next demagnetization of one or both windings of the electromagnet V , the armature 139 falls back, letting go of the arm 148 and moving against each other. sets the rear stop, in which position it now inhibits the arm 149 at the end of a following half turn. This device ensures a certain advance of the paper corresponding to one full revolution of the escapement for each back and forth oscillation of the armature 139, regardless of the length of time during which the armature is held against its front stop. The end of the telegraph is therefore able to advance the paper precisely by a desired length, all that he has to do is to manipulate his switch 102 a corresponding number of times. The various drive wheels connecting the escapement to the feed rollers are expediently dimensioned in such a way that the space through which the paper is advanced by one revolution of the escapement corresponds to the line spacing. It is noted that this pulling device pulls the paper forward independently of the circumference of the paper roller, and that consequently the subsequent adjustments of the paper, each corresponding to one revolution of the escapement, are completely uniform. So that the paper always lies properly flat on the base 117, a lever 157 Fig. 2) and 3) is clamped by means of adjustable clamp 15 8 with strong friction on the shaft 7 and connected at the free end to the frame by a spring 162, which seeks to rotate the lever in the opposite direction to the direction in which the feed rollers pull the paper. The movement. of the clamping lever is limited by stops 159, i6i. If the pulling rollers are in action, the tensioning lever rotates with it up to the stop 159, whereupon the pulling of the rollers overcomes the friction between the lever clamp and the shaft 7; If the feed rollers are then inhibited, the shaft 7 is rotated back as a result of the strong friction of the clamp by the lever under the tension of the spring 162 and the paper is accordingly tensioned.

At the sending station, the same procedure is initiated at the same time as the paper is shifted at the receiving station by the fact that (Fig. 13 and 13 a) battery y is connected by wire r to a closing strip 163 of the switch and this strip is connected to closing springs 164, 16 5 when changing over loops, which on the one hand by wires r ¹ and r ² with the circuits BEZW. s and t have connection in front of the electromagnet V of the transmitting station.

For the purpose of automatically restoring the coincidence of the two springs, if they have been lost, each time the paper is adjusted, the device has been made so that the activation of the electromagnet V causes the rollers 94 to be released from their inhibitions, whereby the same

can follow the impulses given to them up to a certain limit. For this purpose, each roller 94 is connected to its spindle by a toothed coupling 47, the two parts of which are held in engagement by the pressure of a spring 49 against the sleeve 50 which presses against the underside of the disk 39. In a groove of the sleeve 50, the fork-shaped extension of the armature 54 of an electromagnet fafst respectively. QQ ¹ . The latter lie in a circuit q (Fig. 13a and 14), which from the battery \ (between its - \ - pole and the electromagnet H) via connector 112, armature 139 of the electromagnet V to battery ^ ¹ (between its - pole and the electromagnet H ¹ then) goes. If electromagnet V is energized, its armature closes the circuit of electromagnets Q and Q ¹ , and these move the sleeves 50 through their armature attraction by means of the driver 109 downward, thereby releasing the connection between the two coupling halves. The rollers 94 are thus free of their inhibitions and follow the drive of the currently operating electromagnet MN respectively. Ai ¹ 2V ¹ ; the. So the G-spring experiences a sudden forward movement. The already described connections of the changeover switch 102 through the wires a and h to the batteries g and f ^l are now chosen in such a way that the currents of the G spring sent when the paper is pulled through the circuits d and e move into one of those of ^ 4 -Feather (which is now placed on the arm ι ο ι) communicate the appropriate position, ie in the upper left corner of the writing field. Having arrived at this point, it is stopped by the fact that the cords 8, 8 ¹ knotted knots 167, 160 (Fig. 13 a) meet against obstacles. As such are used in the examples shown on the. Rods 33, 35 adjustable crosspieces ι ιό, 111 with holes through which the cords are drawn.

To switch on and off the prime mover supplied with power by a special battery, an interrupter is arranged in the relevant circuit i and set as a function of the relays PP ¹ . It consists of a block 198, on the metal part of which sits a closing spring 197 (FIGS. 9, 10 and 10), which is connected to the armature 199 of an electromagnet L , the winding of which consists of many turns of a fine wire, so that only a weak current is required for arousal; it is connected by wires ww on the one hand to the wire s coming from the armature 133 of the relay P ¹ and on the other hand to the wire t coming from the armature 132 of the relay P, whereby it: finds itself switched on each time in one of the branch circuits of the battery y when, the same is closed via one or the other relay armature. According to FIGS. 9 and 10, the armature 109 is rotatable both in the horizontal and in the vertical direction. As soon as it is torn off by its spring 202, a pin 200 fixed to it comes into engagement with a screw without an end 201 arranged on the spindle 30, which slowly moves it to the right against the tension of a spring 204, opening the secondary spring 197 pulls over the non-conductive part of the block 198. When the armature experiences attraction again, it is loosened from the screw and spring 204 pulls it back against the stop 203, bringing the closing spring back onto the metal part of the block. This facility is made so that BEZW when the paper shift. the establishment of correspondence between the two points where both armatures 132, 133 are attracted (as a result of the switching off of the resistors /? R ¹ ) and L loses its current, the engine does not come to a standstill.

As with the writing telegraph described in patent specification No. 49275, a switching device is also provided here, by means of which the transmitter or the receiver is placed on the line at each point. It is illustrated in FIG. 5 and its electrical connections in FIG. 13. It consists of a cylindrical block 174 which is seated at the lower end of a spindle 109 which is freely rotatably mounted in the table. The latter is provided with an arm 120 which carries a double fork 171, 172 for inserting the .A spring when not in use. Four approaches of power springs slide on the block; two of the same 175, 176, 177 and 175 ¹ , 176 ¹ , 177 ¹ are in connection with the lines bc , namely the incoming line b is applied to 176 and the latter is on the receiving position of the switch on its closing strip 178 (Fig. 5 ); likewise the spring 177, from which the current path goes through the electromagnet H into the earth. If the transmission is switched over, 176 and 175 come to rest on the closing strip 179, while 177 steps on the non-conductive part of the block. This puts b in connection with the breaker B. In the same way, the connections of the line c with the closing springs 175 ¹ , 176 ¹ , 177 ¹ and their interaction with closing strips 178, 179 are permitted. The other two sets of spring springs 180, 181, 182, 183 and 180 ¹ , 181 ¹ J 182 ¹ and 183 ¹ are in connection with lines d and e, namely the incoming line d is connected to 183, and the latter is included the receiving position on the receiving strip 184, as well as 180, which the connection to the electromagnets J and P

manufactures. There are 182 in the send position and 183 on the cut out. Closing strip '185, on the other hand 181 and 180 on the non-conductive part of the switch.

182 is connected to arm 86 of interrupter B via changeover switch 102 and resistor R , so that the current from gg ¹ goes directly via 182, 183 into line d. 180 ¹ , -181 ¹ , 182 ¹ and 183 ¹ cooperate with terminal strips corresponding to 184, 185, and are related to line e in the same way as just described with regard to, d. The changeover switch is adjusted automatically, in that when the A- spring is inserted into the double fork, the springs 70 of the two interrupters turn the double fork, i.e. the block 174, into the receiving position (which is the normal one) by pulling on the spring tip while tensioning a spring 190, which now, as soon as the .Α spring is removed from the double fork, turns the switch back into the transmission position. The adjustment is limited by stops 188 and 189.

Are inserted at both locations, the A -Federn, the two strong line ZZ batteries ¹ are turned off and only the two weaker ■ {\ turned ^l, whose currents, however, offset since these batteries are connected oppositely; The batteries gg ¹ and ff ^{1 are also} switched off in both places. If an A spring is inserted, the two relays PP ^{1 are} de-energized at the other point and the engine comes to rest after a few revolutions; if both A springs are inserted, the engine rests at both points. If a yl spring is then added, the. relevant point, the batteries ZZ ¹ switched on and energized as a result of the current transmission of one of the relays PP ¹ at the other (receiving) point, causing the engine there in motion. Thus, all facilities of the receiving station are in the hand of the sender.

As already mentioned, since the A- nib and G-nib are never in action at the same time, the arrangement has been made that the writing pad 117 is common to both nibs, in that the nibs supporting the plate 118 are made so strong that that they only yield to the stronger pressure exerted by the A -spring. The center line of the writing field serving for sending is in Fig. 1 by the dotted line D and the center line of the writing field serving for receiving is through the. dotted line D ¹ . It also designates D "the lower, D ' the upper limit of the writing field used for sending, D the lower and D'" the upper limit of the writing field used for receiving. So both writing fields overlap. When the A- spring is inserted, it rests so high above the paper that the G-spring can move under it and its cords 63 and 64. ■ So that the G-spring does not block the path of the ^ 4-spring when transmitting, the arrangement has been made that when the ^ 4-spring is inserted, 1. two positive currents are sent through the circuits d and e, so that both Relays P and P ¹ tighten their armatures and the resulting excitation of the electromagnet V closes the circuit q of the electromagnets QQ ^l , with the release of the rollers 94 from their inhibitions, and 2. the electromagnets JJ ¹ adjust their armatures so that the Rollers 94 pull the arms 21, 22 back in the center line of the paper into the point marked / (Fig. 1), in which they stop by the meeting of the knots of their cords with their holdings. For the purpose of this current transmission, two closing strips 57 (only one of which is visible in the drawing in FIG. 5) are arranged on the changeover switch 174, and the two closing springs 181, 181 ¹ , of which 181 through line j (FIG. 13 ) with battery g in front of the end piece 88 and 181 through line k with battery / ^{1 in} front of the end piece 88 ^: is connected, whereby + current from g around R via 181, 57, 183 ¹ to d, and likewise. + Current from / ^{1 flows} around R ¹ via .181 ', 57, 183 ¹ to e . The strips 57 are arranged in such a way that the current connections are established immediately after the " A- spring" has been inserted; in order to maintain it for a long enough time, the switch arm 187 is connected to a fluid brake 191, which slows down the rotation into the receiving position Rotation back into the sending position, however, remains without influence. In order to prevent the G-spring from resting on the paper when not in use, which can easily lead to soiling of the paper and clogging of the spring, a support is arranged at the point of rest Z. , consisting of a narrow, hard and liquid non-absorbent rail p, which extends a little above the paper from the side parallel to its upper edge to the point /; its edge facing the G-spring is gently roofed off (Fig. 2), so that the spring slides up slightly and thereby lifts itself off the support 32 in order to exclusively and specifically with its tip for the purpose of sealing it tightly against ρ to support. If you want to send, you take the A -spring out of the double fork and move it slowly back and forth at the point where the tip is in the rest position to ensure that the electromagnets M ¹ JV ¹ MN at the receiving point properly raised

are; then one leads the spring into the point of agreement (i.e. against the arm ιοί) and thereby causes the G-spring to move out of - the rest position in the Point of agreement moved. By adjusting the switch 102 is on both Set the paper shifted, as well as by the automatic adjustment of the switch 174 the engine of the transmitting station has been engaged, so that everything is now ready for transmission and is ready to receive.

Fig. 15 shows a modification of the electromagnetic reversing device. A brass sleeve 59 is pushed onto the detached part 45 of the electromagnetic core 27, separated therefrom by a non-conductive sleeve 58, on which a brush grinds, which feeds the current to the winding arranged between the soft iron jacket 10 and the non-conductive disc 14. On the spindle 98 inserted through the core, with a friction sleeve jj between two collars 60 and 61, sits a brass sleeve 62, and on this, starting from disk 14, is arranged: a hard rubber disk 83, a soft iron disk 82 firmly connected to it, tightly adjoining one .Disk 81 and a hard rubber washer 80 firmly connected to sleeve 62. 81, 83 and 82 sit loosely on 62 with intermediate storage. Von Reibungshülsen; 82 and 83 can shift slightly between 14 and 81, for which purpose 83 fits into a longitudinal slot of 62 with a pin 84. A spring 196 clamped between the ring 90 and the disk 82 seeks to push the disks outward. If current flows through the winding, 82 is drawn to the core 27 under tension of the spring 196 and rotated by the spindle 98; Sleeve 62 also takes part in this rotation. On the other hand, the disk 8 has become free so that it can rotate freely in both directions. If the current is interrupted, the spring 96 pushes the armature disk 82 back and thereby the disk 81 is clamped between the disks 83 and 80. The sleeve 62 with all the parts arranged on it can now be rotated in both directions, taking the disk 81 with it. Two electromagnetic clutches set up in this way are arranged opposite one another on spindle 98 (FIG. 17). The one just described is the one on the left; the parts of the right side have the same numerals with the shopping \ Of the discs 81, 81 ^v skid two cords 113, 113 ¹ 39 in opposite sides of the disk to the attachment points of the two cords opposite sides of the discs 81, 81 ^l conceives a cord 114 (Fig. 16), which runs around a roller 11 5 mounted in the forked carrier 116 from one disk to the other. One between that '. Bearings of the wearer and a spring 122 clamped onto the end of the shaft keep the cords taut. Inside the spring a sleeve 124 sits loosely on the shaft, which, in the case of both discs 81, 81 ^x are clamped at the same time between 83 and 80, or if the friction between 81.81 ^l and sleeves 62 is correspondingly strong, the same-

'Prevents both ends of the cord 114 from being wound up early, in that in this case the carrier is pulled forward and the nut 123 runs against the sleeve. A weight 126 is attached to each disk 83 by means of a cord 125. The spindle 98 does not form a continuation of the drive spindle 30 here; at its end a soft iron disk 127 is fastened by means of a spring and nut, which for .usually close to the core and jacket of a clutch electromagnet D (set up as the one described with reference to FIG. 9) and is firmly connected to the spindle 30. The connection between spindle 30 and engine shaft is intended to be established by worm gears. The electrical connections are:

The current flows from the battery O ¹ through the conductor u and then branches off: the one branch current flows through the conductor κ ¹ , the. Shaft 30, the winding of the electromagnet D, the brush 210, the conductor u ", the switching tongue 211, the rail 213, the switching tongue 214 and the conductor u '" back to the battery. The other branch current flows through the conductor χ and the spindle 98, where it ^{branches into the windings of the electromagnets X 1} F ¹ , on the one hand from the winding of the electromagnet Y ¹ via the brush 215, the conductor x ¹ , the connector 19 and the Armature 52 of the electromagnet J 'back to the battery, on the other hand from the winding of the electromagnet X ¹ over the brush 216, the conductor x ", the socket piece 20 and the armature 52 of the electromagnet J ¹ back to the battery. The cords 125, 125 ¹ run through the ends of the switching tongues 214 and 211, which are provided with slots for this purpose, and lift them ^{off the rail 213 by means of their nodes 217, 217 1} , whereby the circuit of the electromagnet D is opened.

Assume that the polarity of the current flowing through the reversing circuit is of the type. that the electromagnet / his' armature is held against the slack piece 20: the circuit of the battery O ¹ goes through the clutch electromagnet X ¹ , while the electromagnet F ^{1 is} switched off. The disk 81 is therefore coupled to the sleeve 62 and rotates under the action of the weight 126, whereby it gives the disk 39 rotational drive in the direction of the arrow in FIG. the

Disk 83 ¹ rotates with the electromagnet X ^{1 and} pulls up its weight · 1 26 ¹ . The disk 81 ^l is free and gives way to the course of the cord 113, which turns it in the direction of the disk 39. Once the weight is raised so far 126 ^one, that. the node 217 'strikes against the key spring 211., the latter is lifted off the rail 213 and thereby the circuit of the electromagnet D is opened. The latter releases its armature disk 127 and the spindle 98 stops rotating, so that the weight 126 ^{1 is} no longer drawn up. The latter now begins to decline, since no inhibiting influence is at work; as soon as the spring 211 snaps back onto the rail 213, the circuit of the electromagnet D is closed again and, as a result, the weight 126 'is pulled up again. In this way the weight moves up and down until the electrical connections are reversed; If this occurs, the weight 126 ¹ sinks unchecked to its lower position and thereby drives the disk 81 ¹ .

If, as a result of the reversal of the direction of movement of the Α-spring with respect to the interrupter C, the polarity change occurs in the circuit e , the same causes the current of the battery O ¹ to be diverted from the clutch electromagnet X ¹ to that of Y ¹ . The position of the parts is now as follows: The disk 81 coupled to its sleeve 62 ^! is driven by the weight 126 ¹ in such a direction that it rotates the disk 39 'opposite to the direction of the arrow in FIG. 17; the disc 81 is free and the disc 13 and the electromagnet Y ¹ pull the weight 126 up.

The stops which contribute to the establishment of the agreement are shown in FIG. 15 16 and 16 and each consist of a pin fastened to the respective disk 81 or projection 225 and an arresting piece 226 fixed in the way of the pin. The full Path length of the G-spring in each of its two drive directions is the width of the inhibitor. Piece smaller than that of a full revolution of the corresponding disk 81 equivalent Path length.

In Fig. 19 a drive device for the G-spring is shown, in which the connection with the engine is mediated by a double gear. The prime mover drives the spindle 30 through gear reduction or a suitable transmission. It is loosely inserted through the hubs of two bevel gears 326, 327. A soft iron disk 328, 329 is attached to the outside of each of the latter, and a clutch electromagnet 330, 331 is attached to the shaft in front of each of the latter On the other hand, the electromagnet is encased in a jacket made of soft iron, which is connected to the core by a disk made of soft iron which the winding lies, is closed off by a non-conductive disk 333 so that the core and jacket protrude somewhat. The latter touch the disk or 328, 329, which is expediently covered with a non-conductive layer. The two bevel gears 326, 327 are in Engagement with a bevel gear 334 fastened on the spindle of the roller 94 and the pitch gear 26. Each of the two bevel gears 326, 327 is connected to a tension spring or 335, 3 37 connected, which seeks to turn the wheel in the same direction as the prime mover and thereby constantly maintains engagement with the third bevel gear. The wheels 326, 327 are of such a size that they never need to be turned more than a full turn in the same direction; On the inside of the wheels 326, 327 fastened pins respectively. 338, 339 limit the rotation of the energized two wheels by their meeting with fixed arresting pieces 340, 341. As in the embodiment already described, the knots in the cords, these stops and retarders are used here to establish the correspondence between -A-spring and G-spring. The armature 52 of the electromagnet J ¹ lying in the circuit e is connected via battery O ¹ and shaft 30 to one end of the windings of the electromagnets 330, 331; At the other end, the winding of the electromagnet 331 is connected by conductor m to one stop of the armature 52, while the other stop is connected by the conductor m to the other end of the winding of the electromagnet 330. During the graphing, the shaft 30. rotates continuously. Depending on the direction of movement of the .Α-spring, a positive current or a negative current is sent through the circuit e and the armature 52 of the electromagnet J ^{1 is} thereby held against the relevant one of its two stops. In one of these positions, for example that which is shown in FIG. 19, the circuit of the batteries O 'via the conductor m and the electromagnet 330 is closed. Mantle and core of the latter be magnetic, and the disc 328 firmly suck & n <, so the bevel gear 326 DAF with the shaft 30 verkuppelt

. will. If the Α-spring is reversed , so. If the armature 52 of the electromagnet J ^{1 is placed} against the other stop, the circuit of the electromagnet 330 is opened, whereas that of the electromagnet 331 is closed, so that the G-spring is now moved in the opposite direction, as the casing and the core of the Suck the electromagnet 331 onto the iron disk 329 and thus couple the bevel gear 327 to the shaft 30.

20 to 29 illustrate a modification in which the circuit breaker BC air resp. Fluid pressure is used.

A thin (sheet steel) disk 230 is fastened to the spindle 66 and is provided on the edge with two concentric rows of the same number of slots 232, 233, which are arranged in relation to one another in such a way that each slot of the one row is in the middle between two slots of the other row. Both rows of slots lie between two blocks 234 and 235 which are screwed together and are referred to as "valve blocks". The lower block 235, according to FIG. 24, has two slots 236, 237 which communicate with a pressure vessel through a tube 238 and are arranged in such a way that they lie immediately below the slots of the outer row 233, with which they are also of the same length. The upper block 234 (bottom view Fig. 23) has two slots 239, 240, which are twice the length of the slots 236, 237, are arranged in the same perpendicular planes with them and are so far apart that if the outer end of one of them, e.g. B. 240 ,. is located immediately above a slot of the row 233, its inner end lies in the middle between two slots of the row 232, and that at the same time the inner end of the slot 239 is immediately above one of the slots of the row 232, while the outer end is in the middle stands between two slots of the row 233. The slots 239, 240 do not go all the way through the valve block 234. The slot 240 is through a tube 241 in communication with a chamber 242 which is defined between a movable plate 243 and a block 244 by the fact that the plate 243 is fixed on a resilient disc 245 (e.g. made of soft rubber) praising ring 246 against block 244. The tube 241 communicates with the chamber 242 by a bore in the block 244. The slot 239 is connected by a tube 247 to a chamber 248 which, in the same way as above, is formed between a block 249 and a movable plate 250 is. The two plates 250 and 243 are connected by means of a cross piece 253 to a rotatably mounted lever 254 made of soft iron, to which the line b is connected at the bottom and the upper end of which swings between electrical connection pieces 256, 258. The end piece 256 is connected by conductor α to the -f pole of the battery y, which is connected to the - pole, and the end piece 258, through conductor a ^{1, is} connected to the -pole of the battery X, which is connected to the + pole. on which lever 254 is mounted consists of a permanent magnet 257 with two lugs 258, 259, against which the lever2 54 hits during its oscillations and thereby closes the magnetic circuit.

If the A -spring receives movement in one direction or the other, the disk 230 is rotated with the roller 227 at the same time. If the latter comes with a slot of the ■ row 233 one of the two slots 236, 237 of the block 235, eg the slot 237 and. a slot of block 234, e.g. Opposite the slot 240, for example, pressure flows from the tube 238 through the disk and the tube 241 into the chamber 242 and drives the movable plate 243 outwards, whereby the lever 254 is placed against the end piece 255. In this position, chamber 248 is in communication with the outside air through tube 247, slot 239 and one of the slots in row 232 of disk 230, so that pressure escapes from chamber 248 and plate 250 is driven inward . As the disk continues to rotate, a full part comes between the slots 236, 237 and 239, 240, whereby both the inlet and outlet paths of the chambers 242 and 248 are closed. However, the slot 236 'now faces one of the slots of the row 233, and a connection is thereby established from the tube 238 through the disc 230, the outer end of the slot 239 and the tube 247 to the chamber 248, while at the same time the inner end of the slot 240 abuts a slot 232 and thus connects the chamber 242 through the disk 230, the slot 240 and the tube 241 to the outside air. The plate 250 is thus driven outwards, the plate 243, on the other hand, is relieved and driven inwards; The lever 254 is moved to the right. These processes are repeated as often as the disk 230 is rotated through the arc corresponding to the distance between two of the slots of the row 232 or 233, and a corresponding sequence of current pulses with alternating polarity is thereby sent into the line b.

The permanent magnet 257 forces the lever 254 to constantly adhere to one or the other of the

Electric circuit pieces 255, 256, so that it can never stop between these two pieces, and therefore always, with the exception of the periods during which the lever 254 changes its position, is full of current in the line. Instead of having a movable plate, both chambers 242 and 248 can also be provided with movable pistons, as in FIG. 27, where the pressure moves pistons 263 sealed in the chambers 264 with respect to the lever 254. Or only a movable part provided and the pressure directed alternately against the two sides, as shown in Figure 28 where the lever 254 by the alternate expansion of two abutting him elastic chambers ^242] and 248 adjusted ^ί. or the adjustment of the lever can be effected in one direction by means of a movable part of the pressure chamber and in the opposite direction by spring force, as in FIG 313 clamped spring is replaced.

Instead of using a pressure vessel, the tube 238 can also be used with a vacuum connect by using the atmospheric air as a pressure fluid.

Figs. 29, 30 and 31 show the device of the receiver when using an air pressure machine instead of the electric prime mover. The air-pressure machine is constructed in such a way that there is a stationary one on each side Plate 278 by means of ring 283, 284 and soft rubber plate 281, 281 (on which it sits) a plate 279, 280 is movably arranged so that two chambers 290, 291 ■ are formed, which by channels in the plate .278 and a yet to be described The valve device communicates with the tube 285 leading to a pressure vessel. The movable plates are through with the levers 276, 277 mounted on the table (expediently hardened steel) rods 286, 287. so coupled that these ends loosely in Sleeves 288, 289 attached to the levers are inserted. The levers work through cords 274, 275 onto the sleeve 39 of the roller 94 driving the relevant guide arm of the G-spring. Between rings 296, 297 fixed on the rods and the rod guides 294, 295 clamped Coil springs 292, 293 constantly seek to push the rods outwards in order to to keep the cords 274, 275 taut. Outside, opposite the levers adjustable stops 298, 299 are used to produce a match between the two instruments.

The mentioned valve device for regulating the pressure can be of any other suitable type. In the example shown, it consists of a slide 301 (Fig. 32). which forms a four-sided hollow body which is permanently connected at the top with the tube 285 and which moves in the sleeve 302 on the seat 303. The latter contains two bores 305 and 306, which BEZW with the chambers. 290, 291 are in connection, and the position of these holes in the valve seat is such, that one of them, z. B. 306, opens into the cavity of the slide 301 when it is in one limit of its stroke, as shown in Fig. 32, while the other has a connection with the external air. If the slide is shifted to its other stroke limit, the bore 305 comes into connection with the slide cavity, whereas the bore 306 connects with the outside air. The slide is adjusted by the armature 308 of the electromagnet J, in that the same strikes against one or the other of the two stops 309 fastened on the slide rod 304. The stroke of the slide rod is determined by hitting the on. their fixed inhibitors 31 ο limited against the guide 307. During the activity of the receiver, the pressure held in stock in a container connected to the tube 285 enters one or the other chamber 290, 291 and drives the plate or the plate. 279,280 to the outside, whereby by means of levers respectively. .276, 277 and cord or. 274, 275 tension is exerted on the roller 94. The receiver is in the condition shown in the drawing and the .4 spring is reversed. The electromagnet J folds its armature 308, displacing the slide 301, so that the chamber 291 communicates with the pressure tube 285 through the bore 306, but the chamber 290 communicates with the external air through the bore 305. While the chamber 290 is compressed, the chamber 291 expands, and so the plate 280 is driven outward against the lever 277 and thus the direction of the tension acting on the roller 94 is reversed.

The line c is of course also connected to such a device.

It is readily apparent that the modifications described in relation to the transmitter the air pressure machine can also be used in the receiver. In Fig. 34, for. B. the loading, Removable plates replaced by pistons 317, 318. Or the device according to FIG. 28 is used, the arm 254 being used is to the train on the roller 94 of the writing .direction accordingly . to regulate, or the device according to Fig. 29. You can also use a vacuum. In this case are only to redesign the connections between the chambers and the roller 94 appropriately, e.g. B.

Claims (4)

as in Fig. 35, where the two rods 286, 287 are hinged to the levers 276, 277 so that they act on them by tension instead of fabric. When they are adjusted, the levers meet two-armed levers 313, from which the cords 274, 275 extend. The chambers are connected alternately with the evacuated space and with the outside air; the former has the inward movement of the movable. Parts, the latter resulting in their return movement.
