The controller works in the following way:

The electronic assembly 11 normally keeps the starting electromagnet 12 energized and, as a result, the armature 17 (Fig. 1) is normally in contact therewith . The armature 17 is released from the electromagnet 12 under the action of the spring 23 and rotates counterclockwise around the fixed shaft 18. By means of the pin 21, the Sohieber 41 pushed forward and causes the lever 42 to counteract

sioh rotates clockwise and the nose 48 comes free from the projection 46. The bracket 49 is now pivoted clockwise by the spring 47, so that its arm 52 sioh detaches from the release tooth 53 of the coupling 54 and it rests against the cam 57 by means of the arm 56. The clutch 54 is engaged and sets the main shaft 33 in a cyclical rotation in a clockwise direction. .

At the beginning of the cycle, the eccentric 32 is from the position 32a brought into position 32b and it causes the connecting rods 31 and 34 to be moved downwards. The pin 36 will then moved from position 36a (Fig. 4) to position 36b, causing lever 37 to rotate clockwise will. Daduroh comes the pin 40 of the lever 37 from the position 40a In position 40b and al result of this, the course * at 39 the rod 29 τ η from position 29a to position 29b, . which causes the rod 26 to be brought backwards from position 26a into position 26b. The movement of the bar

909830/0826 -9-

26 backwards brings the armature 17 into contact with it again the electromagnet 12, through the slide 22. Since the start signal ends and the electromagnet returns to its normal, excited state is returned, the armature 17 is now together held back with the slide 41, whereby the spring 44 remains tensioned. The kinematic chain now takes the one shown in FIG. 4 position shown in dashed lines.

The cam 57 then causes the bracket 49 to rotate counterclockwise, whereby the arm 52 in the path of the release tooth 53 of the clutch 54 arrives. The nose 48 is raised again and releases the lever 42, which can rotate under the action of the spring 44, and the projection 46 back under the nose 48 brings, whereby the bracket 49 is locked in the position of FIG is held.

The eccentric 32 (Fig. 1) will continue to rotate brought into position 32o (FIG. 4) and causes the two connecting rods 31 and 34 to be moved upwards and move pin 36 to position 360. The lever 37 rotates consequently counterclockwise, whereby the pin 40 reached position 40c. The connecting rod 31 brings in this way the rod 29 in the position 29c and the rod 26 in the position 26c. The slider 22 is through the anchor 17 held back because the electromagnet 12 is energized. As a result, the spring 23 is under tension.

The eccentric 32 (Fig. 1) is then in the position 32d (Fig. 4) brewed and causes the connecting rod 34 downwards,

909830/0826 -10-

the connecting rod 31 is moved upward. The pin 36 comes to position 36d, causing lever -37 to turn clockwise rotates and brings the pin 40 in the position 40d. The connecting rod 31 then moves the rod 29 into the Position 29d and the rod 26 in position 26d of maximum height. In this way, the kinematic chain takes on the in Fig. 4 position drawn in strioh-dotted lines *

As it rotates further, the eccentric 32 (FIG. 1) closes its position 32a (Fig. 4) back and so lifts the connecting rods 31 and 34 downwards so that the pin 36 in the Position 36a reached. The lever 37 rotates clockwise and brings the pin 40 into position 40a. The crank 39 moves the rod 29 back to position 29a and thus the rod 26 back to position 26a, which closes the path will.

From this it is clear that the rod 27 is cyclically in a first direction shifts, namely from the position 26a to 26b, around the armature 17 with security on the electromagnet 12 at the moment when it is excited, and it shifts in a second direction from the Position 26 ο naoh 26d.

At the beginning of the cycle, the eccentric 72 (FIG. 2) is in the deijot position 72a (Fig. 5) and it is at an angle of 125 ° clockwise offset with respect to the eccentric 32. When the rotation begins, the eccentric 72 is brought into the position 72b, the corresponds to the position 32o of the eccentric 32, and he leads the

909830/08 26

both connecting rods 71 and 73 upwards. The pin 74 moves from the position 74a to the position 74b, so that as a result the lever 76 rotates counterclockwise and the Brings pin 77 from position 77 "to position 77b. The crank 78 moves the rod 69 from the position 69a in the Position 69b, which is why the rod 66 moves from position 66a to position 66b. The slide 62 follow the forward movement of the rod 66 under the action of their springs 63, move the armature 61 away from the electromagnet 16 and bring it the lugs 92 under the corresponding lugs 94 of the rods

If the rotation is continued, the eccentric 72 comes to the position 72o (FIG. 5) and causes an upward movement of the connecting rod 71 and a downward movement of the connecting rod 73. The pin 74 moves into the position 74o and the Lever 76 is rotated clockwise so that pin 77 is brewed in position 77o. By the crank 78 is the rod 69 in the position 69o and the rod 66 in the position 66o of their axial height, that of the position 26d of the rod 26 corresponds, brewed. The kinetic chain thus does not apply the position drawn in strioh-dotted lines in FIG. The noses 92 of the slaps 62 are brought close to the top, but they grasp not against the lugs 94 of the associated rods 82, there the latter are ready to be raised to their rest position.

The cam 152 (Fig. 1) then causes the lever 154 to rotate counterclockwise, and this lever acts by means of of the component 156 on the microscope holder 157 "in, by moving it in the middle position near FIGS. 1 and 3 into the position shown in FIG

brings the position drawn by the dash-dotted line, to close the contact on line 159. To this In this way, an impulse is given to the electronic arrangement 13, which controls the transmission of a group of signals to the electromagnets 16 via the lines 14. The electromagnets l6 are thus waü. wisely or selectively excited.

In the meantime, the eccentric 72 (Flg. 2) has been brought into the position 72d (Fig. 5) and thus pushes the two connecting rods 71 and 73 downwards. The pin 74 comes in like this the position 74d and causes the lever 76 to rotate clockwise. The pin 77 reaches the position 77d and by means of the crank 76 pushes the rod 69 into position 69a and rod 66 in position 66d. The rod 66 brings the slides 62 close backwards and each of these slides brings the associated armature 61 into contact with the corresponding electromagnet 16. In this respect, the kinematic Chain the in dashed lines in Flg. 5 drawn shape.

Upon further rotation of the eccentric reaches 72 (Fig. 2) in its initial position 72a (Fig. 5) back and lifts the two Verbindungsatangen 71 and 73 ^to · De? Pin 74 is returned to position 74a and causes lever 76 to rotate counterclockwise. The pin 77 thus moves into the position 77a. The crank 78 brings the rod 69 back to the position 69a and the rod 66 is brewed forward to the position 66a. The path shown in FIG. 5 thus ends. The ones with the armatures 6l, which those electromagnets 16 associated slider that are not energized

62 follow the rod 66 under the action of the springs 63 their forward movement, while those with the energized electromagnets 16 connected slide 62 are retained by the associated armature 6l.

In the meantime, the cam 152 (FIG. 1) allows the Lever 154 rotates clockwise. The component 156 acts on the microswitch 157 and brings it to the position shown in FIG. 3 Position shown in dashed lines, so that the contact to the line 158 is closed. In this way a pulse is given to the electronic arrangement 11, whereupon the start-up electromagnet 12 is de-energized and the solenoid-operated electromagnet 121 is excited. The electromagnet 12 (Fig. 1) controls the bracket 49 in the manner already described. which in turn controls clutch 54, which is engaged. The electromagnet 12 then returns to its normal, excited state State back.

The eccentric 32 (Fig. 1) begins a new cycle, is of the position 32a is brought into the position 32b and causes the rod 26 in the manner already described from the position 26a (Fig. 4) is moved to the position 26b. The slides 22 and 124 bring the armatures 17 and 123, respectively, into contact with the corresponding electromagnets 12 and 121, the both are aroused.

If its rotation continues, the eccentric 32 (Fig. 1) from position 32b (FIG. 4) to position 32c and causes the rod 26 to move forward from position 26b in FIG

909830/0826

the position 26c. However, the slide 22 remains duroh the Armature 17 in its rearward position, while the bracket is reset by the cam 57 in the manner already described will. Likewise, the slide 124 remains in its by the armature 123 of the electromagnet 121, which is excited rearward position and as a result of this, the nose 128 of this slide retains its position below the shoulder 129 the rod 132.

The eccentric 72 (FIG. 2) also begins its second revolution or cycle, is brought from position 72a (FIG. 5) to position 72b and causes the rod to be displaced from position 66a to position 66b. The slide associated with those electromagnets that are not energized 62 continue their forward movement and come with their noses 92 to lie under the lugs 94 of the rods 82 while the sliders 62 associated with the energized electromagnets remain in the rearward positions with the noses 92 under the lugs 93 of the rods 81 ~. The cam 118 causes the lever 113 to move around the fixed shaft 114 in the Rotates counterclockwise. In this respect, the bracket 109 pivots clockwise and comes from the notches 108 of the Slide 98 free.

With further rotation, the eccentric 72 (FIG. 2) comes off the position 72b (Fig. 5) to the position 72o and causes an upward movement of the rod 66 from the position 66b to Position 66c. The slide 62 are brought near the top and

909830/082 6

by means of the noses 92 push the rods 81, which are associated with the energized electromagnets 16, upwards. With Rods 82 connected to those electromagnets 16 which are not energized are already raised. The on this Way shifted rods 81 cause a rotation of the respective rocker arm 86 clockwise, which move the associated slide 98 forward, while with the non-energized electromagnet 16 associated slide 98 remain in the rearward position. The selector rails 107 connected to the shifted slides 62 are therefore swiveled selectively in the counterclockwise direction and as a result of this, the selector rails 107 assume a position the code signals received through the electromagnets 16 reproduces.

The cam 118 now allows the lever 113 to rotate clockwise. Therefore, the bracket 109 is pivoted counterclockwise and is back from the notches 108 detects what the sliders 98 and the selector rails are from 107 remain set, the latter being used to select the character to be printed.

The cam 152 in turn causes the lever to rotate counterclockwise, which acts on the microswitch 157 and brings it into the position shown by dotted lines in FIG. 3, in order to make the contact through line 159 sohlieesen what controls the transmission of a new set of signals from the electronic assembly 13 to the electromagnets 16. This group of signals represents the character to be printed in the following cycle,.

In the meantime, the eccentric 32 moves from the position 52o to the position 32d and brings the rod 26 from the position 26o up to the position 26d. In this way, the slide 124 is brought upwards and, by means of the nose 128, pushes the rod 132 upwards, so that the rocker arm 135 must rotate in the clockwise direction. The sole lever 143 is pushed forward and causes a pivoting of the universal machine 148, which in a known manner causes a soling process. In this way a printing of the first selected line is obtained. The eccentric 32 (Fig. I) is then brought into the rest position 32a to the position 32d (Fig. 4), woduroh the second cycle is terminated "This causes a displacement of the rod 26 from the position 26d to the position 26a.

In the meantime, dtr Nooken 152 (Fig. I) allows that lever 154 rotates clockwise. The component 156 acts in the catfish already described on the microso holder 157, the contact to the line 158 is closed and a pulse reaches the electronic arrangement 11, depending on which the signals are sent to the electromagnets unl 121 are transferred.

In the meantime, the eccentric 72 (FIG. 2) continues its rotation and moves from the position 72c to the position 72d. Diq & tange 66 is moved from position 66c to position 66d brought and-leads the armature 6l to contact with the electromagnet 16. Then when the eccentric 72 from the position 72d IA the position 72a passes, the rod 66 is from the position, ment 66d brought into the rest position 66a, what the second

It will be understood from this that when the rod 66 is slid in the direction from position 66b to 66c, it will selectively move the Rocking levers or control elements 86 are actuated, which reflect the state of the electromagnets 16.

When the sequence of characters to be printed is complete, all electromagnets 16 are de-energized by making contact with line 159. If there is a contact with the Line 158 is established, the stop solenoid 121 is de-energized and so is the start solenoid 12. As a result the main shaft 33 then performs one more revolution. The new rotation of the main shaft 33 causes the eccentric 72 (FIG. 2) executes one revolution and thus triggers a displacement of the rod 66 along the path shown in FIG. 5. When the rod 66 is in position 66b, in which way all electromagnets 16 are de-energized, the cheeses 92 are the Slide 62 all below the associated lugs 94 of the Rods 82. When the rod 66 reaches the position 66o, the slides 62 are guided upwards, with all those Rods 82 are brought up, which are not already in this position. In this way, the rocker arm 86 in Turned counterclockwise and bring the slide 98 naoh

The main shaft 33 also has the effect that the eccentric 32 is a Rotation executes, which in turn causes a movement of the rod 26 along the path of FIG. If this rod is in the position 26o, then the nose 128 of the slide is located 124 under the approach 131 of the rod 133. Get the rod 26 to the position 26d, the rod 133 is brought up and causes the rocker arm 135 in a counterclockwise direction turns. The slide 143 is moved backwards, whereby the universal rail 148 rotates clockwise must, what causes the end of the stopping process.

When the microswitch 157 is connected to the line 158 again is to give a pulse to the electronic assembly 11, the electromagnet 12 is not de-energized. In order to the bracket 49 remains with the arm 52 in the path of the release tooth 53 of the clutch that is disengaged and consequently the device stops.
