Teletypewriter

The invention relates to a teleprinter having a device for height control of a type carrier and for control in a type selection level in both directions from the Has rest position off for the selection of the type, the settings under control of the The armature of the selector magnet is carried out in conjunction with cam disks and the armature has two positions can occupy, between which he is distinguished by the characters of the received signal combinations emotional.

The invention aims to make the selector device for such a machine particularly simple and designed so that it can be operated easily and has a high transmission speed is aimed.

The machine according to the invention is characterized in that each of the settings controls Cam disks having a valley into which their associated scanning lever is pulled and the one Cam disk back follows, which cooperates constantly with the associated scanning lever, and the different cam troughs, timed with the key characters, are arranged in such a way that that the movement of a feeler lever in a valley is blocked if at this time the anchor has a assumes certain of his two positions upon a corresponding sign, and that each

Scanning lever actuates one of several slide rails when scanning the valley of a cam disk, one or more of which shift a gearbox, which defines the direction in the type selection level in which the type carrier is to be actuated, in the several other slide rails actuate the stops that the movement of the type carrier in limit the specified direction, and actuate several other slide stops that ίο limit the lifting of the type-bearing element.

According to one embodiment of the invention, a type segment is divided into four horizontal sections and divided in half. Each half has four vertical rows of characters in each toggle position on. The characters on the type segment are arranged for dialing so that upon receipt the letters and digits by characters with character stream characteristic of a predetermined thus the impulse of a five-character system can be represented and are on one half of the segment. Letters represented by characters with an isolating current feature are located on the other half of the segment. Sign-responsive devices are activated upon reception certain impulses the segment in one direction or another depending on the character of the received Seeking impulses to move. Separation stream or character stream that occurs during the other pulse periods will determine the height to which the segment will be raised and the angle of rotation calculated from the zero position regardless of the direction of rotation. Responsive to characters Means will selectively move a series of three segmented stops. The stops have segment-shaped stop projections to regulate the distance. The type segment will split into one or the other looking to move in another direction. The pulses received in two of the pulse periods will control the setting of these segment-shaped stops, whereas the pulses in the other two pulse periods are received that control the height to which the type segment is raised will. A periodically actuated device causes the type segment to rotate and close certain times during operation to move upwards. By optionally to be set The rotary and upward movement of the segments at several angular positions and are medium interrupted at different stroke steps.

The machine generally described here has thirty-two choices. However, if more than thirty-two species, required the type segment can be switched, similar to switching to large or small Lettering is done on the typewriter. This switching device has an arrangement to all segment-shaped stops a small distance when receiving characters that require a toggle supposed to trigger to move. The brief description above deals in particular with the selection the types to be used for printing a letter or number. The machine can be used for strip printer or page printer. Both are under construction Apparatus almost alike.

In the case of the strip printer, the various actuations that differ from that of the typewriter differentiate between executed prints, controlled by optionally set key rails, a switch lever or a reset lever move to a certain position by a spring force when a certain key is set on the key rail. By moving one of these levers, the machine now becomes brought into the switchover position or into the reset position. When the character sent is a toggle or triggers a return stroke, the print hammer, which is constant with the strip printer is actuated and can be moved into the printing position as a result of the spring pressure, on the printing of the Streak prevents, and instead of performing a pressure, the force in the pressure hammer is applied actuating spring stored and used to set the switching position or the return stroke position. The levers regulating this operation are levers biased against theirs by springs Move the spring preload to a position in which it is from an approach ainer with the print hammer moving device are taken, creating the group of segment-shaped Stops is displaced in that the lever preloaded by the spring on the segment-shaped Attack bearing plate are attached. For switching to numbers contains at In the normal five-letter alphabet, the character, with the exception of the third pulse, is only character stream pulses. The key for the letter switching or for the reset switching is also a character stream pulse · The third pulse is used to control the direction of rotation of the type segment used. In the case of a string printer, the type segment, when it is in its highest position and has performed its furthest turning movement has a switch lever or a reset lever. One the type segments into one or the other direction biasing spring can move the segment-shaped stops and cause a switchover. Set the first and last pulse of the five-unit key the segment-shaped stops to determine the amount of movement of the type segment. Of the second and fourth impulses determine the lifting height of the type carrier. The third pulse sets the direction of rotation fixed.

In the case of a page printer, the line feed and the carriage return must be carried out in addition to the work steps required in the case of strip printers. The device for obtaining the distance is somewhat more complicated because the separating current symbol for carriage return must be given as the simple strip feed symbol. The device, however, is controlled in almost the same way as the tape printer, in which the operation is carried out by sliding

Rails are regulated, optionally by cam disks selector be driven to select the key rails to be operated. Additionally to the main cam disks is the coupling for a second cam disk arrangement actuating trigger is provided which just before the main cam discs terminate their period have triggers to provide the force to actuate the selected assembly. Through this to cam disks, either a pressure is initiated or a job is carried out when setting the following, characters to be printed by the machine.

In all the figures, the same reference numerals designate the same parts; so the number 31 in Fig. 1 designates the base plate on which the machine is attached, which is divided into several individual devices, which are provided with different reference numerals, so ¹ the voter magnet with the number 32 (see. Fig. 2 and 3) the drive device with the number 33, the selector device with the number 34 (cf. FIGS. 3 and 6), the device actuating the type segment with the number 35 and the strip feed device with the number 36.

The selector magnet 32 (see FIGS. 2 and 3) has a main support block 40 with two horizontal ones Spacer supports 41 and 42, which in turn are connected to an anchor rotator plate 43 is. On the support 42 there is a pin 44 to which a spring 45 is attached at one end while its other end is attached to the anchor 46

and usually seeks to rotate armature 46 clockwise away from magnetic core ^ / of the selector magnet. The voter magnet has two coils 48 and responds to the signals which are given by a transmitter of a remote office or of the office on which the teleprinter according to the invention is located. The windings and cores forming the magnet 32 are mounted on the support block 40. The armature 46 is connected to the armature bearing plate 43 by a leaf spring 49 which is riveted to the armature 46 at 50 (see FIG. 1) and is screwed to the bearing plate 43 at 51. Another plate 52 (see FIG. 3) is attached to the upper end of the bearing plate 43 and carries an upwardly directed rod 53, at the upper end of which nuts and lock nuts 54 and 55 are provided for adjusting the armature. The drive device 33 (see FIG. I) has a motor which is fastened to the base plate 31 and which is connected to a power supply system. It is either a synchronous motor or it has a control device that regulates its rotational speed. On its shaft 67 sits a worm gear wheel 68 which meshes with another worm wheel 69 which is mounted on the right end of the shaft yo . The shaft 70 is mounted in two brackets 71 and 72 fastened to the base plate. Several sleeves 74, 75, 76 and JJ are provided on it (see FIG. 5). The sleeves 74 and 75 serve as spacers to keep the wheel 69 in relation to the wheel 68 and the sleeves 76 and JJ between the brackets 7i and 72 in the correct position. The sleeve 75 is fixed to the shaft 70, and the sleeve j6 is free to rotate about the shaft 70. The sleeve 75 carries a drive coupling 78. A drive coupling and several cam disks are attached to the sleeve j6, which set various machine parts in rotation at certain times. The drive coupling 78 is designed as a ratchet wheel and represents a unitary whole with the sleeve 75. Since the sleeve 75 sits on the shaft 70, the drive coupling will always rotate when the motor 66 is connected to voltage.

On the sleeve 76 there is a fairly large washer 85 and on this again there is a spring support 86, a spring guide member 87, a pawl carrying arm 88 and a pawl stop 89 attached. Several springs 90 are attached to the spring support 86 and locate the pawls 91 in FIG move in such a direction that the pawls engage the teeth of the ratchet 78. The disc 85 is connected to the sleeve 76 by a plate 92, which has arms which against push disk 85; The plates 92 are connected to the disk 85 by screws 93. on The sleeve 76 (see Fig. 6) are fitted with twelve cam disks which actuate the various devices in a suitable sequence. These cam disks ^ gl. 6 from right to left) are the armature lock cam 94, the type segment movement cam 95, the cam disc to limit the lifting of the type segment 96, which the segment-shaped stop actuating cam disk 97, the cam disk for returning the Type segment 98, the cam disk 99 actuating the segment-shaped stop, the cam disk to limit the lifting of the type segment 100, the type segment movement cam 101, the cam disk for adjusting the Key rail 102, the cam disc to enable the key rail 103, the cam disk for operating the print hammer 104 and the Cam plate for lifting the type segment 105. The cam plates on the sleeve 76 control not only the various devices of the typewriter in the selective actuation of the selector magnet 32, but they also act on the various parts of the printing apparatus. The cam discs 95, 96, 97, 99, 100, 101 and 102 form part of the machine's selector mechanism and each has a cam follower lever 123 to 129, which can be rotated on a shaft 130 (cf. Fig. 3), which are mounted on a support block 131 is on which an armature locking lever 132 (see. Fig. 5) and a center stop lever 133 (see. Fig- 3) are attached. The anchor lock lever 132 prevents armature movement to the magnetic core 47 except when the cam back the armature locking disc is in engagement with the armature locking lever. The anchor lock lever will again kept away from the valley of this cam when the anchor is tightened. Of the The anchor is in the rest position, the normal position when the machine is at rest is located. To operate the typewriter, an isolating current pulse is sent as a start pulse. A character current pulse serves as the stop pulse. Therefore, if the machine displays a sign and then the stop pulse or the character current pulse have been received, the armature is attracted. Shortly thereafter, the armature lock cam moves the armature lock lever away from the armature. The anchor can fall off and comes into engagement with the armature lock lever and brings its locking bolt 134 (see. Fig. 6), in the way of the pawls 91. The pawls then no longer engage in the gear on and remain in this position until a start pulse, i.e. H. receive an isolating current pulse during which the armature of the electromagnet will have fallen off and the armature lock lever can be moved under the action of its spring towards its cam. A part of At this time, the cam disk will face the lever 132. This way the clutch becomes actuated and the operation of the cam disks on the sleeve 76 is then in the following Way of proceeding:

The upper, front ends of the sensing levers 123 to 129 are then operated so that they are in the Engage the end of the anchor and not be able to move to the right (see. Fig. 3); if the anchor 49 is moved to one of its positions at this time, the valley becomes a special one Touch lever associated cam plate face this touch lever, whereby some Push-button lever on a forward movement on

Character stream characters and other tactile levers on a forward movement in response to a separator character be prevented. These tactile levers, which are prevented from moving forwards during this time, are moved backwards when the cam back of the disc is opposite the feeler levers, without any effect on their associated slide rails. If, however, a tactile lever can get into the front position by

ίο that its upper end is not in the anchor 49 in the Position engages in which the valley of the cam disc is scanned, then the feeler lever moved forward and the slide rails can fall behind the feeler lever to be actuated by this to become. When the feeler levers are moved backwards by the fact that they are connected to the back of the cam their associated disks are in action, the various operations in the Machine running.

According to the timing diagram in FIG. 7, three levers simultaneously feel the valleys of their associated cam disks from, namely the feeler levers 123 and 128, which belong to the cam disks 95 and 101, and the feeler lever 129 assigned to the cam disk 102 is. The upper end of the button 123 for the cam plate 95 is formed such that when receiving a character stream pulse, the feeler lever 123 can move forward when the valley of its cam is opposite to it.

In this case, therefore, when a character current pulse is received, the slide rail 113 becomes behind their associated cam switch 123 fall in order to be actuated by him when this the cam back scans. If, however, during this time, in which the feeler lever 123 is opposite the valley of his associated cam plate 95 is located, an isolating current pulse is received, the forward movement of the tactile lever 123 prevented, and its slide rail 113 can not be behind him fall. On the other hand, the feeler lever 128 is designed so that it moves forward at a separating current symbol emotional. Its associated slide rail 118 will fall behind it and be actuated by it when the cam back of the disc 101 comes into action with the feeler lever 128. the Cam 102 for adjusting the key rail is during the same period of time as well as the cam disc ready for actuation for the type movement. The upper end of the tactile lever 129 is shaped so that the slide 119 is behind him upon receipt of character power pulses may fall, whereby the slide rails 113 and 119 are moved backwards at the same time when during their selection position a character stream pulse is received. The slide rail 119 instructs their surface incisions to make a selection, which will now be described in detail meet.

The slide rails 113 and 118 are usually in action with the type segment movement lever 144 and 145, the rounded, rear ends of the slide rails 113 and 118 engage in the recesses. The springs that pull slide rails 113 and 118 into the indentations in levers 144 and 145 are weak. A spring 146 (see FIG. 3) is provided for each of these separate slide rails 113 to 119. The springs 146 are not strong enough to move the levers associated with the slide rails. Much stronger springs 147 pull these levers forward. The levers 144 and 145 are rotatably mounted on a pin 148 which is attached to a block extending upwards from the base plate 31. The upper ends of levers 144 and 145 are connected to two sliding racks 150 and 151 by springs 152 or 153 which usually urge lugs 154 and 155 on racks 150 and 151 against levers 144 and 145. Incisions in them allow the racks to slide freely on pins 156 and 157, the guidance of which holds the teeth on the racks in engagement with opposite sides of the gear 158. The pin 157 has a shoulder 159 (see FIG. 3) in order to carry the lower rack 151. The pin extends upward from an irregularly shaped frame 160 which in turn is attached to the upper ends of brackets 71 and "J2" and to two rear brackets 161 (see FIG. 5). Frame 160 also has two on its surface short rods 162 and 163 (see. Fig. 6) attached, which serve with the pin 157 as a carrier of a T-shaped plate 164 (see. Fig. 1 and 3) on which the guide pin 156 is attached.

When the slide rail 113 or the slide rail 118 has been selected and thus its associated feeler lever 123 or 128 in action with the The slide rail 113 can be brought into the valley of its associated cam disks 95 or 101 or 118 behind their tactile lever 123 or 128 fall. It is moved backwards when the lever scans its associated cam back. If any of the slide rails 113 or 118 has been selected, it will move backwards and thereby the associated lever 144 or press 145 backwards; here the associated rack 150 or 151 is moved backwards moves and rotates the gear 158 clockwise or counterclockwise (see. Fig. ι or 4). By selecting one of the type segment levers 144 or 145, the gear 158 is thus converted into a moves in the two directions dependent on the choice and move a type segment 165 at the same time (cf. Fig. 3), as later in the description of the operation of the armature 49 controlled Camshaft is explained.

The disk 96 following the camshaft is the slide rail 114 and the feeler lever 124 (see. Fig. 5) assigned. It controls the height to which the type segment 165 is raised, iao select a type series for printing. The slide rail 114 is at a considerable distance from the rear end of the slide rail 113 and has a slot 170 at its rear End on (see. Fig. 8). A pin 171 is on an arm of a U-shaped lever 172 by a rivet

173 fastened and engaged in the slot 170, see above that when the slide 114 is moved backwards, the U-shaped lever 172 is rotated about its axis 174 which in turn on the supports 175 extending upwards from the base plate 31 and 176 is attached. The other arm of the The U-shaped lever 172 has an extension piece 177 on, which is in action with a widened part 178 of a sliding axis 179 on which The top end of the type segment 165 is attached when the lever 172 is in its clockwise position is biased by a spring 147. The axle 179 can slide in the gear 158 and will turn with him like that. But you can also move axially to him. When the slide rail 114 is selected and moved backwards, when the feeler lever 124 touches the cam back of the Disc 96 scans, the extension piece 177 come free from the widened part 178 of the axis 179; the type segment 165 can be raised so far that the widened part 178 over the extension piece 177 is lifted.

Another U-shaped lever 180 that corresponds to the U-shaped lever 172 resembles, is through the slide rail 117 actuated at their election, which in turn is actuated by the feeler lever 127, which is through control of armature 49 is selected and moved by cam 100. The left one Arm (see. Fig. 8) has an extension piece 181 which limits the movement of the type segment by that the widened part 178 of the axis 179 comes into effect when the slide 117 is not selected for an operation and is in Moved counterclockwise against the tension of their spring 147. Also rotatable around the axis 174 mounted between the arms of the U-shaped levers 172 and 180 is a lever 182 with Approaches 183 and 184, which come into action with the widened part 178 of the axis 179 and determine how high the type segment is raised during the working cycle. To the Lever 182 is not associated with a slide rail, but it has a spring 147, which .ihn usually seeks to move forward, same as the U-shaped levers 172 and 180. The lever 182 is meanwhile always actuated as often as one of the two levers 172 or 180 is moved backwards is that a link 185 through it in the way of the adjacent arms of the U-shaped lever 172 and 180 protrudes.

In the manner described above, one of the slide rails 114 or 117 is selected for its actuation and subsequent rearward movement will result in the U-shaped, selected slide assigned lever 172 or 180 moves backwards and thus also lever 182 moves backwards move back. 8, the approach 184 is the deepest of the approaches 177, 181, 183 and 184, if therefore the lever 172 or 180 is operated the approach 184 cleared from the path of the widened part 178 of the axis 179, so that the axis 179 can move the type segment upward until the widened portion 178 engages the boss of the unactuated U-shaped lever comes. If neither of the two U-shaped levers 172 or 180 has been selected, then the widened part 178 of the axis 179 with the shoulder 184 is in action come, whereas the type segment when either lever 172 or 180 is actuated is so far raised until the extended part 178 to the approach on the non-actuated Lever engages.

It is thus clear that the amount by which the type segment is raised is controlled by the levers 172 and 180 is controlled. In other words, this degree is due to the selection of the various Approaches by which the upward movement of the type segment is stopped are defined. When a Character is received that is not on the U-shaped Lever 172 or the U-shaped lever 180 acts, by moving one backward, the deepest shoulder 184 becomes the widened portion 178 prevent it from moving upwards. When the U-shaped lever 180 is moved backwards, the lever 182 is guided with it, and the widened part 178 on the axis 179 is with the Approach 181 come into effect. If, on the other hand, both levers 172 and 180 are moved backwards, the approach 183, which is always in the path of part 178, will serve as a stop against which the expanded portion 178 will move; here the type segment 165 is in the highest position guided, and the bottom row of types is brought into alignment with the print hammer, which is in the each will be described later. The type segment 165 moves in each working cycle under the print position to make the last type symbol visible. It then moves up until it is stopped by the action of the widened part 178 with one of the stops.

The next disk on the cam axis is disk 97 for actuation of the segment-shaped stops to which the feeler lever 125 is assigned, which is under control of the anchor 49 will choose the slide 115, if the character received at this time, during which the valley of the cam disk 97 is sensed by the lever 125, a character stream symbol, is. Receipt of a character stream character at this time causes lever 125 to move forward move and the slide 115 fall behind the lever 125 so that when the cam back the disk 97 acts on the feeler lever 125, this will push the slide 115 backwards. That rear end of the slide rail 115 is supported in recesses of a lever 191. This lever 191 (see Figs. 3 and 4), extends upward and engages a lug portion 192 on the segment-shaped Stop 193, which together with two identical stops 194 and 195 from a plate 196 is worn. This support plate 196 is attached to the upper frame plate 160 and is moved around a guide sleeve 197 in which the axis 179 slide and around which the gear 158 is can turn. At its rear end, the carrier plate has a pin 198 which

savings of the segment-shaped stops 193, 194 and 195 engages and with the guide sleeve 197 together the segment-shaped stops in their Directs movement backwards. The plate 196 can be rotated by a device described later move the guide sleeve 197. A pin 199 is attached to the upper frame plate 160 and engages into one or the other edge of the U-shaped cut rear end of the plate 196,

ίο to set them in one of their positions. the segment-shaped stops 193, 194 and 195 have the same shapes with respect to their side view. Everyone has approaches (see. Fig. 4) that as Attacks against a portion of the arm 200 which is attached to the gear 158 and engage when the segment-shaped member is moved. The racks 150 and 151 are depending on their Determine the direction of movement, which side of the segment-shaped stops come into engagement, to stop the part of the arm 200. The lower stop 195 has an extension 201 which extends inward to the midpoint, the open parts of the stop. This extension 201 has a pin 202 so that when one the other two stops 193 or 194 are moved backwards, the segment-shaped stop 195 is carried. The stop 194 can be actuated by a lever 203, which is similar to the lever 191 will. The lever 203 can follow through the slide rail 116, which is identical to the slide rail 115 be moved at the rear.

According to the above, it follows that the segment-shaped stops moved in the same way as the lever which block the upward movement of the type segment. The segment-shaped stops are out of the way of part of the arm 200 depending on the position of the armature 49 to cleared of the time when the associated lever scans the valley of the associated cam disk. In particular becomes the distance at which the springs 152 and 153 move the type segment back and forth can be determined by the position of the segmentformigen stops in accordance with the received characters can be optionally set. When the segment-shaped stop 193 to the rear, are the approaches of the stop 194 in the path of the valley of the Arm 200, and the lugs on the inner surface of the stop 195 are out of the way of part of the Arm 200 cleared, as a result of the action of the pin 202 and the movement of the stop 193 is initiated.

In other words, the segment-shaped stop 193 becomes the segment-shaped stop 195 carry with them. In the same way, when the segment-shaped stop 194 moves backwards will move the part of the arm 200 until it is with the approach to the segment-shaped stop

193 comes into effect that the segment-shaped stop 195 with the stop

194 is moved. If both segmental stops 193 and 194 to the rear, are moved, guide the segment-shaped stop 195 with itself, and the part of the arm 200 can move in either direction, wherein the direction of movement depends on which of the two springs 152 and 153 is tensioned until the part of the arm 200 abuts against the edges of all segment-shaped stops. All approaches are moved out of the way of arm 200. When a character is received that no movement one of the two segment-shaped stops 193 or 194 triggers to the rear, then the Approaches to the segment-shaped stop 195 the size of the movement of the type segment in limit both directions. The type segment is moved by the spring 152 or 153, the are biased against the approaches on the segment-shaped stop 195.

According to the above, the pressure position of the type segment area is determined by a limitation in the Reciprocating and set in the lifting of the type segment. The selection of the print position the type segment area is determined by the key pulses received from the voter magnet and determines the position of the armature 46 if at that time the particular cam is on the Cam disk shaft 70 is in a certain position. The reciprocation of the type segment also takes place optionally depending on the received characters. The device for lifting the type segment into its by the type segment stop arrangement certain situation works in the same way in each working period and is described afterwards will.

The device actuating the type segment to move the type segment into the various positions to move, which are determined by the segment-shaped stops and the spring force that determine the direction of rotation of the type segment also has an arrangement that invariably seeks to move the type segment to its uppermost position. To a certain Time 'in operation, this arrangement takes effect and is from the cam axis driven. The cam disk 105 (see FIG. 2) provides the force for lifting the type segment. This cam disk engages at a certain time during the rotation of the cam disk, to move a feeler lever 211 which is rotatably mounted about the pin attached to the support 213 is. The support 213 (see. Fig. 2) and an identical support 214 (see. Fig. 3) also carry a plate 215, on which the springs 147 are attached. The supports 213 and 214 are at their lower end on the Plate 216 attached on which the slide rails 113 to 119 are stored. The plate 216 has notches around the downwardly extending portions of the rails 113-119 and around the upwardly extending parts of the feeler lever 123 to 129 to receive. This record is also on recessed at their rear end. In these recesses fit through the slide rails 113 to 119 actuated lever and are brought into the correct working position.

The feeler lever 211 (see. Fig. 2 and 5) through the type segment lifting cam 105 is operated protrudes backward and becomes ordinary pulled down by a spring 217 attached to the rear end. On the other end the spring 217 is attached to an articulated arm 218. When the lever 211 is moved by the gradually rising cam plate 105 scans, moved by the camshaft, the articulated arm 218 is together with the rear End of the feeler lever 211 move upwards. The arm 218 (see. Fig. 2 and 5) is rotatable with the lever 219 (cf. FIG. 5) is connected at its center point, one end of which is connected to the support 161 is rotatably mounted. Its free end protrudes below the end of the axis 179 (see. Fig. 3). To the arrangement just described, the type segment is forced to periodically according to the Rotation of the sleeve 76 to move upward. Its movement is indicated by that previously described Device interrupted by which the type segment is stopped when various levers are applied to bring the selected lever of this type into pressure position. The upward movement the axis is stopped by the stop device controlled by the received character.

Besides the lever for lifting the type segment by lifting the axle 179, there is one further device provided to regulate the axis movement. This device is from controlled by the cam 98 for the return of the type segment. The cam 98 is scanned by an irregularly shaped feeler lever 220 (see. Fig. 3), the rear of which is whole-shaped The end of the widened part of the axis 79 can attack to the axis in its deepest Position to move so that the type segment in its lowest position during a certain time is brought in the rotation of the sleeve 76. The front end of the lever 220 protrudes upward and engages the rack 150 or 151, which has also been moved forward when determining the direction of rotation of the type segment. This * 5 part of the lever will reliably move the racks back to their normal position, whereby the type segment is in its middle position.

The pressure hammer cam disk 104 (see. Fig. 5) is scanned by the lever 221 (see FIG. 2), which is rotatable about the on the supports 223 and 224 attached pin 222 is mounted (see. Fig. 2 and 3); lever 221 is usually clockwise attached to the pin by a fairly strong, on this lever and the base plate 31 Spring 225 preloaded. The rear end of the lever 221 is curved like a bow (see. Fig. 5, 226), its upward part, the arm 227 with an equal arm 228 by rivet and screw 229 is connected. The arm 228 forms part of the bow-like member 230 which has a fixed to it, has upward arm 231. This link 230 can also be around the pin 222 turn and is also with the feeler lever 221 connected by screw and nut so that it engages with the lever when it is operated will move through the associated cam disk.

On the upwardly projecting, left part of the lever 221 (see FIG. 2), the arm 232, there are two Hebei 233 and 234 attached. The lever 234 is curved at 235. This curved part 235 protrudes in the path of the rotatably mounted lever 236 (see. Fig. 2), which is usually mit'dem part 235 is acted upon by a contractible spring 237. The lever 236 is rotatable with a arm 238 attached to the underside of plate 160 and extending downwardly from plate 160, tied together. The upper end of the lever 236 is designed as a pawl and stands with a Ratchet wheel 239 in action, which is connected to a sleeve 240 on which a gear wheel 241 and a conveyor roller 242 sit. The sleeve 240 can be a fixed one attached to the plate 160 Rotate axis 243.

At the fixed axis 243 there is a support 244 to which a cantilever lever 245 is attached which carries a freely rotating knurled roller 246. This role 246 is through a on the lever 245 and on an upstanding one Pin 248 attached spring 247 (see. Fig. 1) brought into action. The conveyor roller 242 can through conventional guides 251 and 252 a paper strip Pull 250 from a supply drum 253. The supply drum 253 is on a disk 254 attached, which in turn is carried by the upper end of a support 255 attached to the end of the plate 256 will; plate 256 is attached to frame plate 160.

Extends upward from plate 160 a rotatable shaft 265 to which a gear wheel 266 is attached, in which the gear wheel 241 is on engages the sleeve 240 and drives it with the ratchet 239 continuously. The top of the axle 265 carries a ribbon reel 267, which is running at a 10s much slower speed than that of the feed roller 242 is moved, with an ink ribbon from a supply reel 268 between two pins 269 and 270 and two lugs 271 and 272 of the plate 273, on which the guides 251 and 252 an- no are brought, is pulled.

Mounted rotatably about the pin 222 and between the arms 227 and 228 of the bracket 226 and there is the print hammer lever 274, at the upper end of which the print hammer 275 (cf. Fig. 3) is attached. The lever 274 is designed in the form of a toggle lever. Its horizontal Arm is connected to the base plate 31 via a spring 276 through which the lever 274 usually is in action with a roller 277 which is fastened by a nut and screw 229. The strong spring 225 pulls the lever 221 downwards continuously when it hits the cam back its disk 104 scans. The print hammer lever 274 is moved forward quite violently and is a little bit against the tension of his

Spring 276 moves due to its inertia, the print hammer against the strip 250 between hitting its guides 251 and 252 and pressing the strip against the ribbon, which is just in front of the paper strip (see. Fig. 1).

The apparatus so far described is for the selection of any one of the thirty-two letters to be printed. It is known, however, that more than thirty-two possible characters must be provided in a teleprinter, since dashes, punctuation marks, numbers , etc. have to be counted as well as letters. Devices are therefore required to print more than thirty-two characters. You steer by shifting in one of the two directions and in one of the four positions of this direction. You move the segment-shaped stops of the type segment a little to the right or to the left when the voter magnet receives a suitable character. The shift is equal to half the distance between two letters, which is selected by the segment-shaped stops during normal operation of the machine. This lateral displacement takes place when a suitable character is received by the device now described.

The slide rails 114 to 117 and 119 have at their edges incisions which correspond to a specific choice, so that they are not used for control purposes of the type segment also serve as rails to allow a choice between the three work processes that determine the type To effect rails 280, 281 and 282 according to the received characters (cf. Fig. 5). These rails 280, 281 and 282 are attached laterally across the slide rails and usually downwardly biased by their springs 283, 284 and 285, rotatable about rod 286 and are guided by a plate 287 to which the springs 283, 284 and 285 are attached. Each of these rails 280 to 282 has an upwardly directed portion that allows the displacement, controls the non-shift and the spacing. Around the plate 196 carrying the stops two levers 288 and 289 rotatably mounted and with springs 290 and 291, one of which is attached to each The lever is attached and the levers seek to turn counterclockwise. the With a suitable selection position of the slide rails 114 to 117 and 119, rail 280 can use the lever 288 move against the force of its spring 290, with its right end (see. Fig. 4) from the stop 292 comes free and the other end of the lever under the action of the bow-like Link 230 upwardly extending arm 231 comes. When the lever is in the one shown in FIG Moved position in which its rear end, the left end in FIG. 4, act on the arm 231 'can, the print hammer assembly when moving into the print position, the arm 231 to Actuate lever 288 which rotates plate 196 clockwise. As a result This rotary movement is the lever 289 by its spring 291 in action with the hook Edge of the stop 293 brought. When this occurs, the force of the spring 225 is through the movement of the plate 196 and its parts is consumed. There will be no pressure as the Print hammer cannot overcome the tension of spring 276. By turning the stop plate around their camp, however, another type series of the type segment is in alignment brought with the print hammer, so that when the next character is received, the one to corresponds to the printing type, the above types are printed, i.e. H. the numbers and the punctuation marks.

Upon receipt of a separator character or a non-shift character, the lever 281 or 282 moved by the associated spring 284 or 285. The top of one of the two levers engages plate 294, which can slide on frame plate 160. Cuts 295 and 296 in them receive the pins 297 and 298 which protrude from the plate 160. The one End of the plate 294 actuates the lever 289, and when the plate 294 is moved by one of the two levers 281 or 282, the lever 289 comes out of action with the stop 293 and in the path of the lever 233. When the lever 233 moves forward by the force of the spring, the plate 196 carrying the stops rotated counterclockwise, so that a switchover is made and therefore printing does not take place. When lever 289 is released from Stop 293 and when the segment-shaped stop members move about their axis, the Spring 290 pull lever 288 upwards until it stops moving again through stop 292 is prevented.

The rail 280 determining the operation is split open. Your lower arm (see Fig. 6) is located under all slide rails 113 to 119. The left end of each lever 280, 281 or 282 protrudes through the guide plate 287 and over the Tip of the lever 299 cooperating with the cam disk 103 (see FIGS. 2, 5 and 6). Of the When lever 299 is moved counterclockwise, it becomes one of the no Rail 280, 281 or 282, which is located in the notches on the surfaces of the slide rails, lead back. This lever 299 brings all slide rails back to their upper position, where they can be selected by actuating their associated tactile lever or where they can also be at rest can stay if the character received by the voter magnet they are not selected and intended for an operation. The lever 299 is rotatably mounted on a U-shaped block 300, which is directed downwards from the plate and also as a pivot bearing for the lever 220 serves.

The previously described embodiment of a tape printer can be of the desired types on .125 the strip 250 when receiving a start-stop

Print the sign of the units of five. With start-stop machines, a separating current symbol is always used as the start pulse. The machine is therefore designed to start working when it receives an isolating current symbol. The armature 46 will be able to move upwards by the force of the spring 45. When the first isolating current symbol is received, the armature will move into its upper position, triggering the locking arm 134 and thus the locking pawl 91, so that they engage in the drive coupling 78. As soon as one of the pawls 91 engages in the drive coupling 78, the pawls 91 are driven by the coupling 78 and their rotational movement is transmitted to the sleeve 76 on which the various cam disks for the actuation control of the machine are seated. The cam sleeve 76 will rotate it in timing with the transmitter sending character pulses to the voter magnet. When the sleeve 76 is rotated, the cam disks will allow the feeler levers 123 to 129 to move towards the cam disk shaft 70 in a timed manner (cf. the time diagram, FIG. 7). If at a certain time segment the valley of the corresponding cam disk is opposite its feeler lever and at this time a symbol current pulse is sent to the voter magnet arrangement 32, then the feeler lever can fall and is no longer held by the armature 46. This condition prevails with the exception of lever 128, which is selected by a separating current symbol and can drop on receipt of such a symbol if it is scanning the valley of its cam disk at this time (see FIG. 8A). Depending on the position of the armature 46, the slide rails 113 to 119 are actuated or not actuated when the levers scan the valleys of their associated cam disks at this time. Received from the selector magnet assembly 32 pulses determine, first, the direction of rotation of type segment, secondly, the amount is raised by which the type of segment, and thirdly, the amount of rotation by which the type of segment rotated by the springs 152 and 153 w ^r ird. When the sleeve 76 is rotated, the type segment 165 is brought into the selection position. The print hammer lever will operate the print hammer to print a selected character or to bring about a gap on the strip without pressure or to switch or not switch the type segment by moving the entire group of segment-shaped stops as described.

In this way, the printing of letters and characters by the apparatus upon receipt appropriate impulses. The type segment is shifted when a suitable pulse is received, and then after receiving a character corresponding to a type in the selected print position to be brought. The machine described is for printing a strip of the is gradually moved into the printing position, suitable. The machine can also be used as a remote typewriter be used. A second embodiment of the invention relates to such Machine that has the basic features of the tape printer described above.

The teletypewriter is different with all of its Dividing apparatus on a base plate 301 of irregular shape (see. Fig. 10 and 11) assembled. A keypad 302 is provided at the front right end of the base plate (see FIGS. 9 and 10), through which pulses can be sent to a cam disk manifold 303. That Keypad has optionally adjustable contacts and slide rails and creates electrical states, which correspond to the selection key characters taken from the distributor 303 and the Selector magnets 304 are supplied. The voter solenoid controls those described later Apparatus parts. The signs can also be given to a remote office. So can the Machine either as a receiver or as a local sender and receiver for telegraph signs to be used. The keypad, the contacts and associated with the actuation of the keys the manifold assembly per se is not the subject of this invention. The distributor 303 is from a shaft 305 is driven via a gear 306. The shaft 305 is in turn driven by a wheel 308, that engages the wheel 307 is rotated. The wheel 307 sits on the drive shaft of the motor 309. This The motor can be a synchronous motor or it can be equipped with a speed governor be that in time coincidence with the speed of the engine on the remote Office is running. The motor 309 is mounted on the plate 301 and its shaft in the on the Bearing blocks 310 and 311 attached to the base plate.

The device just briefly described in connection with the teleprinter will later be called the drive device and will be explained in detail. In order to be able to more easily understand the structure of the exemplary embodiment according to the invention, each of the individual different units will be described separately. The drive device 312, are listed by the number u ₀ details before, consists of several configurations. In addition to the driving device 312 are a selector magnet arrangement (see. Fig. 10), a selector assembly 314 (see. Fig. 9), a one type segment operated arrange- n ₅ voltage 315 (see FIG. FIG. 19), a carriage assembly (see Fig. 13), an arrangement 317 executing special operations (see FIG. 11) and an arrangement 318 conveying an ink ribbon (see FIG. 9) are provided. While these various arrangements overlap in their operation and control the machine, they will be described separately where possible for a better understanding of the invention.

The drive device 312 (cf. FIGS. 9, 10, 11 and 13 ') has in addition to the gearbox for driving the

Shaft 305 has two separate clutches, one of which is the arrangement for the particular Actuation and the other drives the type segment selection or control device. Freely movable with respect to the shaft 305, a cam disk sleeve 325 is provided on which from the left the following disks are attached to the right (cf. FIG. 11): a friction disk 326, a stop disk 327, a locking cam disk 328, a ίο cam disk to control the direction of rotation 329, a cam to control the lifting

330, a cam to control the lift

331, a cam for controlling rotation

332, a start cam 333, a cam for controlling rotation 334, a trip cam 335, a clutch release cam 336 and a friction washer 337. The friction washers 326 and 337 are associated with friction washers 3318 and 339 which are located between

ao the disks 326 and 337 and cooperate with the disks 340 and 341. the Disks 340 and 341 are connected to and driven by shaft 305, whereas the disks 326 and 337 are not attached to this shaft, but can rotate with it. Left A spring 343 is provided from the friction disc and is wound around a neck sleeve 344 and usually the disc 340 presses against the friction discs 338 and 339. The friction disc 341 is part of the sleeve 342 attached to the shaft 305. In this arrangement The disks 340 and 341 seek to continuously rotate the disks 326 and 337 and thus the rotary movement the cam sleeve 325 to transmit.

An isolating current is used as the start impulse on this machine. Located on the long-distance line character stream, wherein, as will be described in detail later, the reception of a separation current pulse initiates the operation of pushing under control of the selector magnet 304. With the drive device and as part of the actuation device 317 there are several cam disks and an eccentric provided to operate the various devices. These The cam disks and the eccentric are mounted on the shaft 305 and can be connected by a coupling, controlled by clutch release cam 336 on cam sleeve 325 will be driven. On the sleeve 342, a clutch lock wheel 350 is attached, which the drive member represents the coupling for the cam disks driving the actuating device. A plate belongs to this clutch lock wheel 350

351. on which several pawls 352 (see. Fig. 13) are attached. The pawls engage the teeth of the ratchet wheel by the force of the spring 353 350 a. This coupling is similar to the coupling of the strip printer described above and operates when releasing the pawls 352 by a stop member, as detailed below is described. The plate 351 is concentrically attached to the cam sleeve 354 on which an eccentric 355, a spacing and line feed actuating cam 356, an operation control cam 357 and a pressure cam 358 sit. The two groups of cams can carry out the activities that occur during operation the teletypewriter. You can choose and type the segment in which to print bring the right position.

The effectiveness of the aforementioned cam disks is controlled by the selector magnet assembly 313, which apart from the selector magnet 304 has a carrier and an armature 361. In its attracted position, the character stream position, the armature can allow the selection of certain levers for actuation, which are assigned to the individual cam disks. Other levers will be described later. The armature 361 carries a lock plate or selector plate 362. It is biased counterclockwise by a spring 363 mounted between a fixed portion of the apparatus and a finger 364 extending downward from the armature. The armature is attached to a leaf spring 365, which in turn is attached to the armature rotating plate 366. As a result of the armature 361 being mounted around a pivot point, when the _go selector magnet 304 is excited, the armature can be moved until the right end of the selector plate 362 hits the adjustable stop 367. At the left end of the selector plate (cf. FIGS. 15 and 22) a lever 368 is provided which limits the movement of the selector plate and thereby also that of the armature 361 in accordance with the tension of the spring 363. The lever 368 is biased clockwise by the spring 369 and is urged against the surface of the cam 328 previously described. The left end of the selector plate 362 engages a U-shaped cut 370 at the upper end of the lever 368. The movements of the selector plate, and therefore those of the armature 361, are limited by the edges of the U-shaped cut. On the base of the U-shaped incision there is a sharp projection 371 which is used to lock the selector plate 362 and the armature 361 in the character stream or isolating current position while the locking cam disk 328 is scanned by the lever 368. According to the above, when the cam disk sleeve 325 is rotated, the selector plate 362 and the armature 361 are alternately released or blocked for movement by the design of the upper end of the lever 368 into which the left end of the heater plate protrudes.

The locking cam disk 328 is scanned by the lever 368. The lever 368 (see. Fig. 1) is on an iao together with levers 380 to 386 Rod 387 rotatably mounted, which is held by its two supports attached to the base plate 301 will. Spacer members are provided between the individual levers. The levers 368 and 380 to 386 face their associated cams 328 to 334 and 336 and are

through this, when they are released for forward movement by the force of a spring 369 (cf. Fig. 15) actuated. The cam 335 is not a lever of the above group, but one associated with sliding trigger plate 390, the purpose of which will be explained later. The left end of the Selector plate 362 (see FIG. 22) is pointed because of the sharp projection 371. This record However, 362 is only pointed at the front on the surface that cooperates with lever 368. Of the The remaining part of this left edge is, as can be seen from several figures, square and cooperates with the stops at the upper ends of the levers 380-386. When the anchor 361 is in its tightened position, plate 362 moves out of the way of the stops cleared on the levers so that the levers can move clockwise when they approach the For the time the plate is not aligned with the stops, scan a valley on its cam. The plate 362 therefore serves to prevent the levers from moving by their springs 369, if on the line connected to the selector magnet 304 the isolating current condition prevails, whereas the levers turn clockwise when a stream of characters is on the line can move, where they can operate their associated slide rails.

The next lever 380 following the lever 368 in the series (see FIG. 14) was through the Spring 369 is biased clockwise. In the time when the valley of its associated cam disc 329 is aligned with its stop, the armature 361 is in its character stream position. The lever 380 will scan the valley of its associated cam 329 and so into a Come position in which its upper end comes in front of the approach 391 of the slide 392. If the The back of the cam of the disc 329 acts on the protrusion on the lever 380, becomes the upper part the lever, if it can turn clockwise as a result of the position of the selector plate 362, Reach behind the extension 391 and move the slide 392 backwards (see. Fig. 14). In the same Way, if the lever 381, 382, 383 or 385 by the position of the selector plate 362 is in Can move clockwise, if its \ ^ origin scans its associated cam disk, the upper The ends of the levers fall behind the lugs on the slide rails 393 to 396 and so the rails for prepare a movement. If then the cam backs of the discs through the lever projections are scanned, the levers will move their associated rails. It happens so that Choice of slide rails for operating the teletypewriter in exactly the same way like the choice of slide rails for operating the strip printer.

According to Fig. 12, each of the slide rails 322 to 396 is provided with a spring 397 which tries to pull the rail forward into its rest position (cf. Fig. 12 or 15) by placing the lower surface of the slide on top of its associated actuator lever rests. 14 and 15 are the slide rails provided with recesses at their rear or left end into which support pins 398 grasp. The slide rails are moved to and fro by a horizontally arranged, comb-like guide rail 389 out. The incisions take the slide rail and guide it and the upper ends of levers 380 to 385. It is attached to the lower surface of plate 399, protrude through the parts of the slide rails 392 to 396. The slide rails 392 to 396 have (cf. 14 and 15) show a series of cuts through which rails 400-404 are selected for actuation will. The slide rails 392-396 serve two purposes in that they act as the operating rails and also upon receipt of appropriate characters by the voter magnet assembly 313 control the type segment. When the type segment is controlled, the slide rails regulate 395 and 396 the rotation of the type segment, the slide rails 393 and 394 the amount, around which the type segment is lifted, and the slide 392 the direction of rotation of the type segment calculated from the rest position.

The plate 399 receives in its cutouts the upwardly directed ends of the slide rails 392 to 396 and is attached to the support columns 414 and 415 g ₀ , which in turn are supported by the blocks 310 and 311. This plate 399 has a pin 398 which is separated from it by blocks and supports a plurality of segment-shaped stops 416, 417 and 418 which are fastened on a plate 419 (see FIGS. 12, 19 and 20). A pin 420 extends upward from the plate 419 and, together with the sleeve 421, guide the segment-shaped stops 416, 417 and 418 as they move to and fro. Spacers are provided between the segment-shaped stops 416, 417 and 418 at the pin 420 and the sleeve 421 in order to separate the segment-shaped stops and to counter the springs 422, 423 and 424 (cf. FIGS. 12 and 20) in their correct position to hold the end of the segment-shaped plates. The pins 425 and 426 on the plate 419 carrying the segment-shaped stops are provided with slots for receiving the springs. The springs 422, 423 and 424 pull the segment-shaped stops 416 and 418 forward. Through slots 431 in the segment-shaped stops, these can slide with respect to the sleeve 421 and the pin 420 when the force of the springs 422, 423 and 424 is overcome by the actuation of one or the other slide rail 395 or 396, by using their levers at Receipt of an appropriate character by the voter magnet assembly 313 can be set and moved backwards.

The operation of the segment-shaped attacks in this teleprinter is as set out here became the same as the tape printer. If the provided with a shoulder 428 Plate 416 extends backwards through the upward extension of slide 396 1 * 5 moved, the segment-shaped stop 418 is

follow its design with an upwardly protruding extension 430 (see. Figs. 12 and 15), which lies in the path of the segment-shaped stop 416, moved backwards with the stop. if on the other hand, the slide 395 is selected and moved backwards, it will be against the extension 429 of the segment-shaped stop 417 and push them backwards. Since the segment-shaped Stop 417 moves backwards, it becomes the common segment-shaped stop 418 as a result of the engagement of the stop

417 against the extension 430 with you. According to the above, the stops 416 and 417 are when one of them moves backwards will take the stop 418 with you.

According to Fig. 12, the stop plate 418 has a fairly small excerpt on showing the rotation of the type segment in a direction that of it depends in which direction the type segment

ao to rotate is limited. But if the segment-shaped stop plates 416, 417 and 418 are not moved from the position shown in FIG. 12, it becomes the type segment The transmitted amount of rotation corresponds to a character spacing, calculated from the rest position. If, however, the segment-shaped stop plate 416 is moved backwards and the takes a common stop plate 418 with it, then the lugs on the stop plate 417 control the amount of rotation of the type segment in either direction and its movement on limit two character spaces. On the other hand, if the segment-shaped stop plate 417 after is moved behind and takes plate 418 with it, the lugs on plate 416 become the Limit movement of the type segment. If now both segment-shaped stop plates 416 and 417 are moved backwards and the plate

418, the type segment can extend to a downward extension 631 rotate, whereas the edges of the cutout of the segment-shaped stop plate abut. To this The type segment is controlled in terms of its amount of rotation through the setting of slide rails 395 and 396.

As previously mentioned, slide rails 393 and 394 control the height to which the type segment is raised. These slide rails are provided with downward extensions.

The downward extension 394 ° on the slide 394 is slightly longer than the extension 393 ° on the slide rail 393 (see. Fig. 14). A support 435 is attached to the underside of the plate 399 (see FIG. 9), on which three toggle levers 436, 437 and 438 are rotatably mounted, which are provided with recesses and also on the underside of the plate 399 attached plate are performed. Levers 436, 437 and 438 are about the support 435 in a clockwise direction by springs 440 biased by spacers are separated from one another and attached to the support 435 in a known manner. The lever 438 (cf. FIGS. 9 and 13) can thereby actuate one of the two levers 436 or 437 by an arm that an upward extension 441 is provided on the lever 438, which in is in the path of the arms of levers 436 and 437. The toggle levers rotate around support 435 in the horizontal plane, and the extension 441 extends perpendicular thereto. While the lever 438 can be operated by one of the two levers 436 or 437, the levers 436 and 437 can be operated by the downward extension on rails 393 and 394 are moved.

From Figs. 13 and 15 it can be seen that the rearwardly extending arms of the three toggle levers are in the path on which a Approach 445 of the shaft 446 moves. The wave is at a certain time during operation the machine pushed upwards by a device described later and so long move upward until lug 445 hits one of levers 436, 437, or 438. Because the wave 446 carries a type segment at its upper end, which has four horizontal type rows, it is clear that when the shaft 446 acts during its upward movement through its approach with the lever 438 stops lifting the type segment when the print hammer is opposite, whereas if the shaft moves up until the lug 445 abuts the lever 437, one second series is brought under supervision with the print hammer. If the wave is now Moved upwards until the projection 445 hits the lever 436, a third series is created brought into compliance with print hammer 449. When the three levers 436, 437 and 438 are moved out of the way of lug 445, the shaft will move upward, until its second extension 450 strikes against a nut 451 surrounding the shaft 446. To this One of the types of the type segregation 447, which is divided into four type series, can be coordinated can be lifted with the print hammer 449. The lifting depends on the character picked up by the voter magnet assembly 313 and subsequent actuation or non-actuation of the slide rails 393 and 393 394 from.

The selector rail 392 controls the direction which moves the type segment 447 into position determined by the setting of the segment-shaped stops 416, 417 and 418 will. The direction of rotation of the type segment is determined by the slide rail 392 by to the movement of a double-sided locking device 452 (see FIG. 18) in connection with a rack 453 or 454 acts. In the rest position of the rail 392, the device 452 engage in the rack 454 (see. Fig. 18), where the locking engaging part 455 of the Lockout device 452 is in such a position that it is in engagement with a lug 456 on the rack 454 extends upward from the locking device 452 a pin 457, iss whereby the locking device from the in Fig. 18

position shown can be moved to a position in which a portion 458 of the head of the locking device can come into action with a shoulder 459 on the rack 453. The racks 453 and 454 can slide between two guide members 460 and 461 that are spatially are separated from each other as a result of the engagement of the teeth in a gear wheel 462, which with the Sleeve 463 forms a unitary whole. The sleeve 463 can rotate with the shaft 446, as can previously described. The shaft can slide on the sleeve 463 so that it is perpendicular to the Sleeve can move back and forth, but rotates with it. The upper and lower guide plates 464 and 465 (see. Fig. 17) are attached to the guide members 460 and 461 to to hold the racks 453 and 454 between the guide members 460 and 461. The whole Arrangement of the guide plates and members is ao attached to four supports 466 (see. Fig. 18), the extend upward from plate 391. There are spacers for the guide links 460 and 461 is provided, and between the plates 399 and an ink ribbon carrier plate 467, the as is also held by the support 466 (see Fig. 15 and 17). The pin 457 attached to the locking device 452 can be controlled by a lever 468 operated by means of a spring 469. In the rest position shown in FIG. 18, the lever strikes 468 against an upper curved stop over the part 470 of the rack 454 and against a lower curved stop over the part 471 of the rack 453 (see. Fig. 15) to the two Gear racks aligned while keeping the type segment in its middle position. The parts 470 and 471 of the racks 454 and 453 form a bearing in which the locking device 452 can slide. When the lever 468 is moved to the right by a device described later (see. Fig. 18), the springs 469 are the slide rail that goes forward in the locking device intervenes, looking to move to the right. The one approaching one of the two racks Locking device pulling it to the right (see FIG. 18) will turn wheel 462 and therefore the move opposite rack to the left, while moving lever 468 to the left one of the two racks 453 or 454 seeks to move back that to the right in the illustrated Position was drawn. Here, of course, the rack on the opposite side is inserted into the opposite direction due to the meshing of the teeth of the rack with the wheel 462. To the guide members 460 and 461, a movable plate 472 is attached, which of two upwardly from the guide members 460 and 461 extending pins 473 and 474 will. The slots provided in plate 472 receive pegs 473 and 474. In another Slot 475 in plate 472 protrudes upwardly directed pin 457. Plate 472 can on pins 473 and 474 are moved. During this movement, the pin 457 and the Locking device 452 moved with it. Here, the locking device is out of action with the rack 454 and brought into action with the rack 453. The sliding motion becomes the Plate 472 by the slide 392 upon the selection of a received character transmitted, the indicates that the type segment should be rotated clockwise (see Fig. 18). This work is performed by moving the slide 392 to the left. The top of the slide rail 392 (see FIG. 18) protrudes into a slot 476 in the sliding plate 472.

Upon receipt of a character stream sign by the voter magnet at the time the lever 380 scans the valley of its cam disk 329, the lever will fall behind the slide 392 can, and later when scanning the back of the cam of its disk 329, the slide 392 can be moved to the left (see FIG. 18), with the slide plate and the pin 457 downwards are moved and the part 458 of the front locking device 452 in engagement with the approach 459 of the rack 453 is brought.

With the type segment mover in this position, at the appropriate time during of the operation, the lever 468 is moved to the right (see. Fig. 18), and it becomes the rack Pull 453 to the right by the force of spring 469. The rack will of course go with theirs Stop movement when the segment-shaped stops stop the movement of the type segment. The spring 469 is tensioned without transmitting any further movement of the rack 453. As a result, when the machine is returned to its rest position, the Slide 392 returned to its rest position. Here, the locking device 452 is in the in 18, in which the part 455 is aligned with the projection 456 on the rack 454 is. When receiving an isolating current symbol, the slide rail is not actuated 392 and the type segment moving device will remain in the position shown in Fig. 18, in which the locking device will actuate the racks 454 to the type segment turn clockwise.

The devices described so far, the drive device, the selector magnet device and the selector operator all work together to operate different parts of the typewriter which determines the letters and numbers to be printed for the print hammer will. The device for actuating the type segment will now be described. In order to start the machine, the previously described friction clutches must be released and the drive of the cam sleeve can be done, which is usually done by a Approach to the left arm of the cam follower is locked, which is in the way of an approach the stop disk 327 is located and in this position serves to prevent the sleeve 325 from rotating with the shaft 305 to prevent. The U-shaped one

right arm of the lever 384 (see. Fig. 11) extends up with the voter plate 362. When the voter plate is in its rest position, d. tr. in a position where the selector magnet is excited is (the normal line condition for a voter magnet is the character current position), will the left end of the plate 362 is in the path of the lever 384. At the reception of an isolating current symbol through the selector magnet 304, the spring 363 becomes the armature 361 and move the plate 362 counterclockwise, removing the left end of the plate 362 from the Clear path of lever 384. The spring 369 associated with the lever 384 is then the lever in the Clockwise and thus the arm 384 °, which is shown in phantom in Fig. 15, from the Path of the approach 327 °, which is also dash-dotted is indicated in Fig. 15, clear. The sleeve and the washer 327 attached to it ao can rotate in the direction indicated by an arrow (see FIG. 15). So will when receiving an isolating current symbol with the trunk line normally energized by the electromagnet 304 a work run of the cam sleeve 325 eins5 passed.

The right cam 336 on the cam sleeve 325 (see. Fig. 11) controls a U-shaped lever 386, the left arm of which with the Cam 336 is in communication and its right arm is in the path of the locking device 352 is located (see. FIG. 13), which is attached to the plate 351. At the end of the working period of the Cam sleeve 325 becomes cam 336 the right arm of lever 386 out of the way the locking device 352 clear. The plate 351 and the sleeve 354 can be removed from the ratchet wheel 350 can be rotated. The cams on sleeve 354 actuate the executing operations Devices of the machine and also serve to lift the type segment and the To provide torque for the type segment.

A rod 485 works together with the eccentric 355 on the sleeve 354, with the other rod End a lever 486 is connected (see. Fig. 13, 15 and 16). The lever 486 is a toggle lever with the lever 468 sits on the sleeve 487. The sleeve 487 can rotate about the axis 488, which is supported by supports 498 and 490 attached to plate 399, rotate. While levers 468 and 486 are rigidly connected to the Are connected to the sleeve, a bracket 491, which is held by the axis that also supports the sleeve, turn around. The bracket 491 has an extension piece 492 extending to the rear which is a nose 493 (see. Fig. 13). The nose 493 engages in the groove created by the lugs 450 and 494 is formed on shaft 446. The bracket 491 has a rearward-facing one Arm 495 (see. Fig. 15), to which a spring 496 is attached, which the bracket 491 around the axis 488 in the Moved clockwise. On the bracket 491 there is an adjustable stop screw 497, which acts on a horizontal arm of the lever 468, whereby the bracket 491 by the action the spring 496 seeks to follow the movement of the lever 468, sleeve 487 and lever 486 until the bracket 491 is stopped on its way, for example, by the fact that the one carrying the type segment Shaft 446 is stopped at some point below its uppermost position as it connects is described with the dialing device. As already stated in this context the upper end of the lever 468 is connected to the pin 457 by the spring 469.

The eccentric 355 transfers the reciprocating motion to the rod 485. The eccentric rod will in turn rotate the sleeve about the axis 488 so that the arm 468 in the movement first clockwise and then counterclockwise is moved to the rack 453 or 454 whichever is selected. The selected rack will turn itself forward, d. H. move to the right (see Fig. 18) when the lever 468 turns clockwise (see Fig. 18). 16) and moved to the right according to FIG. 18, whereby the rotary movement on the gear wheel 462 is transmitted.

The device just described thus becomes the type segment in one of the two directions to turn and also seek to lift into its uppermost position. The segment-shaped stops 416, 417 and 418 are used to limit the rotation of the Type segment. The toggle levers 436, 437 and 438, which act on the lugs 445, serve as limit stops for optional upward movement of shaft 446.

The carriage is supported by two brackets 500 attached to opposite ends of the base plate 301 and 501 (see Fig. 11) are held. A horizontal rail 502 attached to the beams carries the front end of the slide. A guide rail 504 having a rack is opened the rail 502 (see. Figs. 19, 15 and 16) through a plate 505 is locked, to which in turn a basket-like container 506 carrying a roll of paper is attached is. The container 506 has two horizontal bottom pieces 507 and 508 and two irregular molded plates 509 and 510 (see Figs. 9, 11 and 16), against which a paper roll leans (see. Fig. 11). The paper roll 501 lies against the rounded ones Edges of the end plates 509 and 510 and is held in place by irregularly shaped Supports 512 and 513 held at a spatial distance from the plates 509 and 510 by Intermediate pieces 514 and 515 are held. Three of these spacers are provided (see Figs. 9, 11 and 12). The supports 512 and 513 serve not only to hold the roll of paper 511 to the end plates 509 and 510, but they do also carry the paper feed mechanism, which will be described in detail later.

On the base plate 301 (see. Fig. 15) is a Print hammer arm 521 attached to support bracket 520; the print hammer is around pin 522 rotatably mounted. On the support 520 is a pressure ias hammer guide plate 523 attached to the two

Rolls 524 carries on the top and bottom of the bottom piece 507 of the paper container to run. The rollers 524 thus guide and support the rear end of the container 506 as it moves across the machine, so that the paper from the paper roll is in the printing position with line spacing to be led. The container 506 carrying the roll of paper is thus attached to its front End through the rail 502 and at its rear end through the running on the bottom piece 507 Roles supported.

The supports 512 and 513 (see. Fig. 11) carry a guide roller 525 and a feed roller 526 which extend across the entire machine between the two supports extend. They are used to pull the paper off the roll 511 as it moves To promote and lead pressure position. The paper is fed to the by two rollers 527 and 528 Supports 512 and 513 with the feed roller 526 held in action and by springs 529 and 530 attached to supports 512 and 513 and two T-shaped levers attached to rollers 527 and 528 are pressed against the feed roller. The rollers 527 and 528 are rotatably supported on the upper ends of the supports 512 and 513 The pinch rollers 527 and 528 are attached to the gears 533 and 534, which are in the opposite Gears 535 and 536 attached to the ends of the feed roller (see. Fig. 9 and 11) engage, causing the pinch rollers 527 and 528 is driven at the same speed as the feed roller 526. With the feed roller Also connected to 526 are two ratchet wheels 537 and 538, those of line feed pawls 539 and 540 are driven. These pawls can move the feed roller during normal operation Operate the machine. However, if a new roll of paper 511 is to be installed in the machine, the feed rollers 526 and the pinch rollers 527 and 528 must be independent of the Pawls 539 and 540 can turn. Therefore, the rightmost end faces the axis of the feed roller 526 a knurled handwheel 541 attached to it, whereby the axis is independent lets turn from the latch. To keep the feed roller in the correct position and to ensure that that the paper is advanced by a designated distance at each step is a locking arm 542 is provided at the upper end of the support 512, its holding roller in the teeth of the ratchet wheel 537 engages and prevents unwanted advance of the paper.

Since the line feed pawls 539 and 540 are equal to each other, only the line feed pawl becomes 539 described in detail (see. Fig. 9). This pawl is at its upper end Including an adjustable eccentric 543 forked, which on the left fork part of the pawl as a result the force of a spring attached to the support 512 and a horizontal arm of the pawl 539 544-acts. The point of engagement of the pawl in the ratchet wheel 537 is controlled by the eccentric, which allows the pawl to engage the ratchet wheel during the downward movement of the pawl to perform the line feed. At the junction of its vertical and horizontal Part of it is the pawl on a horizontally extending arm of a line feed bracket 545 rotatably mounted, which has an arm extending transversely over the carriage and with a roller 546 held at the end of a line feed lever 547 by the action of the spring 544 in action will. The remaining part of the device for actuating the line feed is shown in detail in Connection with the operation of the arrangement 317 performing a particular activity is explained in more detail.

When the machine is in operation, a letter or character will be printed at any time if the character for printing has been selected by suitable position of the type segment. The device for carrying out the pushing will now be described first. The print hammer 449 leads this work is carried out with a blow against him that exceeds a certain strength. He will be in one Incision 555 guided in the guide plate 523 (see. Fig. 15), which over the paper roll 511 and then curved upward to receive the print hammer. The print hammer turns on its rear end held by a pin 556 which moves in a slot 557, the is provided at the upper end in the lever 521 operating the print hammer. The hammer is located usually in its withdrawn position, i.e. it is passed by the type segment a spring 558 attached to it and to a nose of the print hammer lever 521 is withdrawn. Meanwhile, if the print hammer lever 521 is so by operating devices described later far forward so that a projection 559 of the print hammer lever against a stop plate 560 hits, the print hammer will overcome the force of the spring 558 due to its inertia and that Press paper from roll 511 according to the type segment. The print hammer lever 521 is around the Pin 522 rotatably mounted and supported by a bead

561 (cf. FIG. 16) is connected to a lever 562. This lever arrangement is a toggle lever. To the lever

562, the arm 563 is rotatably supported, the other end of which with a pressure cam plate lever 564 is connected. This lever 564 is held against the pressure cam 358 by a strong spring 565 drawn, and due to the design of the cam 358 (see the diagram in Fig. 21) become the arm 563 and consequently also the print hammer lever 521 snap forward and so the print hammer trigger lever 564 from the back of the cam move its associated cam, unless a stop 566 on the arm 563 against a Inhibition that prevents the arm from moving forward to its extreme position. The escapement is in the way of the stop 566, if a pressure is not to take place,

z. B. when an operation caused by a separating current, a carriage return or a line feed should be carried out.

The other actuating devices only work when no pressure is to be applied. These works can optionally be implemented by choosing one of the operating rails 400 to 404. These Rails partially control the character switching, the line feed, the spacing conditional operation, the carriage return and the blank activity. The rails 400 to 404 are rotatably supported on a shaft 567 mounted above the plate 399 and are rotated around their shaft is biased clockwise by a spring 568 each (cf. FIG. 17). On the right At the ends of the rails 400 to 404, a lever 569 is provided for returning these operating rails, which holds them in their upper position during the movement of the slide rails 392 to 396. The lever 569 has the shape of a toggle lever which is located on the lower side of the plate 399 can turn and with his vertical arm the

ao scans control cam disk 357 (see. Fig. 11 and 16).

At the appropriate time during operation, as can be seen from the timing diagram in Fig. 21, the lever 569 will be moved counterclockwise to approximately that shown in this FIG Assume position and with this actuation one of the actuation rails 400 to 404 in a opposite incision of the slide rails 392 to 396 drop. At this moment of the Operation when the return lever 569 moves down and the operating rails 400 to 404 released for actuation by its springs 568, one of the rails 400 to 404 can turn around rotate its axis clockwise if no letter or character is selected for printing has been, but when the voter magnet assembly 313 has received an actuation signal. If such an actuation is to be carried out, then of course there should be no pressure, and as a result, a jamming device is intended to move in the path of the stop 566 of the arm 563 to prevent the print hammer from thrusting forward enough to cause pressure. Such an obstruction device is in the form of a curved nose 570 on the push lock rail 571 (see. Fig. 16) is provided. This rail is usually pulled up by a spring 572 and has at its upper end a recess into which a pin 573 protrudes, which is fixed to a curved approach of the plate 399 is connected and as a support for this and for three more, later described pressure lock rails is used. The pressure lock rail has a widened head portion 574 (cf. FIG. 17), which extends over the outermost ends of the actuating rails 400 to 404. The feather 572 is weaker than the springs 468 so that when the slide rails 392-396 are in mating position are located around one of the operating rails 400 to fall into their opposite incisions to let the spring associated with this rail move the operating rail downwards, whereby the pressure lock rail assumes its lowest position, in which the nose 570 is in the way of the stop 566 is located. When the toggle operating rail 404 is selected, not only the Pressure lock rail 57i, but also a clearance switch-off rail 575 can be moved downward. if line feed operating rail 403 is selected by slide rails 392 to 396, then will they the pressure lock bar 571, the distance switch rail 575 and a line feed rail 576 downwards against the force of the corresponding Move springs 577 and 578.

When the clearance actuating rail 402 is selected, it becomes the push lock rail 571 push downwards. When the carriage return actuation rail 401 is selected, it becomes the Carriage return rail 579, the clearance switch-off rail 575, and the pressure interlock rail 571 move down. When blank sign actuation rail 400 is selected, its spring becomes it Rotate about its axis and the distance switch-off rail 575 and pressure lock rail 571 downward move. In other words, require the character switching, the line feed, the carriage return and the blank actuation, the exclusion of distance and pressure, and these locking rails are therefore operated.

Since one character is printed at all times in normal operation, one becomes a space inducing actuation carried out. The one causing the line feed and spacing Cam 356 has a lever 585 associated with it, which is usually in action with its cam disc stands and with an irregularly shaped, extending backwards Arm 586 is rotatably connected. At the rear end of the arm 586 a pin 587 (see. Fig. 13) is provided, whereby the arm is rotatably mounted to a toggle lever 588. This toggle lever 588 can rotate about point 589 on support 590 attached to the underside of rail 502. At A pawl 591 is rotatably attached to its free end. The spring 592 searches around the pawl 591 to move the fulcrum with the toggle lever, usually using the operating end of the The pawl 591 can be caught in the teeth of a rack 593, which in turn is supported by a rack guide rail 504 is attached to the underside of the container 506 carrying the paper. no

From the foregoing it is clear that upon receipt of an isolating current sign by the voter magnet assembly 313 the slide rails 392 to 396 can be adjusted to the distance causing the The rail can be rotated clockwise (see. Fig. 17), whereby the print hammer locking rail 571 is moved downward and its nose 570 in the path of stop 566 on the print hammer actuator arm 563 brings and thus creates a distance without any pressure being applied. Similarly, when you receive one it becomes too printing character by the selector magnet assembly 313 the type segment in the selected position is moved and no actuator rails are aligned with the cuts in slide rails 392-396 be into which they can fall. Hence will

the actuation causing the distance in time Relate to the printing process during a work cycle.

A spring drum 594 is attached to the support 501, in which a flexible cord 595 is wound by the spring in the drum seeks. The end of the string 595 is attached to the sled at 596 and searches for the sled move to the right (see Fig. 17). On the move to the right, the slide is reluctant to move The pawl 597 is prevented from engaging the teeth of the rack 593 by the pressure of the spring 598 grasps. The pawl 597 (see. Fig. 17) is rotatably mounted on the underside of the rail 502 and is hold the rack 5 93 in the position to which it has been advanced by the pawl 591 during operation. To When printing a line of the desired length, the carriage can move to the right by the force of the Spring 595 are returned in that the ao pawl 591 and the retaining pawl 597 triggered will.

Upon receipt of a carriage return sign by the selector magnet assembly 313, the slide rails 393 to 396 are brought into a position in which the rail actuating the carriage return can fall into opposing incisions in the slide rails. When the carriage return actuating rail 401 is moved by spring force, it will move the clearance switch-off rail and the pressure lock rail as well as the carriage return rail, thus preventing the pressure and spacing. The carriage will return by releasing the pawls 597 and 59 ¹ . The arm 563 carries a pin 605 (see. Figs. 16 and 17) which protrudes vertically from the arm in front of the pressure lock rail 571, the distance switch-off rail 575, the line feed rail 576 and the carriage return rail 579, so that when the arm 563 is actuated, the pin 605 will grasp the rails and move them to the left (see Fig. 16). Each of these rails, with the exception of the carriage return rail, has a cut at its lower end (see Fig. 16) in order to cooperate with a square bolt 607, whereby when one of the rails is moved downwards it is locked in this position by the action of the bolt 607 until the pressure arm 563 is moved and the rail pushes to the left and thus freed from the latch 607. The carriage return rail does not have a cut at its lower end and is therefore not held in place by rail 606.

The distance switch-off rail 575 and the carriage return rail 579 (cf. FIGS. 13 and 16) have projections 608 and 609 which act on locking release levers 610 and 611. The levers 610 and 611 are rotatably mounted about a pin 612 which is attached to a support 613 fastened to the base plate 301. The lever 610 is a toggle lever whose vertical arm is located behind the pawl 591 (see. Fig. 13), so that when it is actuated, the pawl 591 no longer engages in the rack. As a result, the pawl 591 will be ineffective even when operated by its device. The cam 358 is designed such that the pressure arm 563 will not bring its pin 605 into action with the rails 571, 575, 576 and 579 until the pawl 591 has been moved over the cutting edge of the next tooth.

The lock release lever 611 also has a vertical Arm up who will operate the latch 591. Another upright, with the first upright Arm connected by a link 614 engages against a shoulder on the pawl 597, whereby upon receipt of an appropriate character by the voter magnet assembly 313, the carriage return is initiated. The two pawls 591 and 597 now do not engage the teeth of the rack 593 a. When the carriage return actuates release lever 611 is, then it is blocked in this position and keeps the pawls 591 and 597 out of action with the rack 593 by a locking bolt 615, which is rotatably mounted on a support 616 (see. Fig. 13) which in turn is attached to the underside of the rail 502. The bolt 615 is in Biased counterclockwise by a spring 617 (see. Fig. 13). If the upward End of the carriage return release lever 611 itself moved to the right (see. Fig. 13 and 16), it is held by the bolt 615 until the The carriage has moved to its rightmost position, where a pin 618 on the underside of the Rail 504 will grasp latch 615 and rotate it clockwise, releasing the lock release lever 611 is released.

When a blank character is received, the operating rail 400 the pressure and the distance adjustment by depressing the pressure lock bar 571 and the distance switch-off rail 575.

A line feed may occur upon receipt of an appropriate character by the voter magnet assembly 313 can be achieved by adjusting the slide rails so that the line feed operating rail 403 can move downwards. When this movement occurs, the distance adjustment will be blocked by actuation of the distance switch-off rail 575. The pressure is through the operation of the print lock bar 571 is prevented, and also the line feed bar 576 moved downwards. As the line feed rail moves down, an adjustable Eccentric 625 guided downwards, and the line feed arm 626 comes into the path of one Lug 627 on lever 585. Line feed arm 626 is acted upon by a spring 628 with the eccentric 625 and usually from the area of the projection 627 on the lever 585 held. When the lever 585 is driven by its cam disk during operation is moved to the left, the line feed arm, as it is conveyed downward into the area of the lug 627 is to be moved to the left and thus rotate the line feed lever 547 about its axis 629. In the rear, forked end of the arm 626 engages one extending upward from the lever 547

Tenon 547 ^s a. Thus, the line feed is completed by actuating the line feed handle 545 and transmitting the rotary motion to the feed roller 526, as previously explained in connection with the description of the paper conveying device of the carriage assembly.

It thus remains only the description of the line switching device, through which either the numbers or letters on the type segment can be set for printing. According to Fig. 23, the type segment has four horizontal type rows, which are divided into sixteen vertical Rows are divided. Choosing any of the thirty-two digits on the Type segment to put them in

To bring it to pressure had been dealt with. This choice is made by raising the type segment up to one of the four rows and then by rotating the type segment by one the setting of the segment-shaped stops 416, 417 and 418 set amount carried out.

The type segment is controlled by the

segment-shaped stops 416, 417 and 418 themselves move in steps of two vertical rows of characters for each particular choice. The different

as positions become, to which the segment-shaped The vertical rows 1, 3, 5, 7, 9, 11, 13 or 15 can be brought up gradually lead into alignment with the print hammer when the group of segment-shaped stops is in one switch position. If, on the other hand, they are in the other position, will the vertical rows 2, 4, 6, 8, 10, 12, 14 or 16 be guided across from the print hammer.

The type segment is attached to the axis 446 and can perpendicular to the sleeve 421 back and forth are moved her, one part 462 of which is designed as a gear, or to which a gear 462 is attached is. An L-shaped arm 631 is attached to the upper end of the sleeve 421 (cf. FIGS. 15, 19

4P and 20). Its vertical part serves as a button for the type segment. Two approaches 632 and 633 on the part 634 of the type segment 447 are with the Sides of arm 631 in action. This causes the type segment to move vertically to arm 631.

According to FIG. 23, there are no characters in the first and sixteenth positions in the bottom row intended. This type arrangement on the type segment was chosen because the Switching takes place when the type segment is to be raised to its highest position, to bring the bottom row into alignment with the print hammer, and there the type segment would have to be turned to the right or to the left in its outer position. The switchover is caused by the movement of the plate 419 carrying the segment-shaped stops around such a Amount made equal to the distance between two adjacent type series on the type segment 447 is. As a result of this movement, all segment-shaped stops 416, 417 and 418 become with it the plate 419 carried along. Two supports 635 and 636 extend upwards from the plate 399 (cf.

19 and 20), around which two locking levers 637 and 638 rotate. These two locking levers are irregular trained toggle levers, and their horizontal arms are by springs 639 down biased. This puts the free ends of the horizontal arms in the way of the inner ones Lugs 640 and 641 brought to plate 419. The upstanding ends of levers 637 and 638 have, as can be seen at 642, cam-like surfaces in order to be connected to the shoulders 632 or 633 to work together. When the type segment is in its uppermost position and in its extreme rotary position upon receipt of a character by the voter magnet assembly 313 indicating a switch Requires has been brought, then it is the approach 633 or the approach 632 under move the cam-like surface on the lever 637 or on the lever 638 depending on its direction of rotation. According to FIG. 19, the shoulder 636 approaches the lever 637. When this against the lever 637 then he will push it against the force of his spring 639, namely the horizontal arm of the lever 637 out of the way of protrusion 640, thereby removing support plate 419 from the end of the Lever 637 comes free. The type segment can then be divided into its extreme counterclockwise division rotate and here the segment-shaped stops 416, 417 and 418 and the Move carrier plate 419 counterclockwise by one character distance. When the plate 419 rotates counterclockwise by one character distance, becomes the end of the horizontal arm of the lever 638 come in the way of the projection 641 on the plate 419 and thereby the segment-shaped Stops 416, 417 and 418 and the carrier plate in the letter switching position lock. Upon receipt of a character corresponding to a digit by the voter magnet assembly 313, the type segment 447 is raised to its uppermost position and to an outermost one Position turned clockwise. This brings the extension 632 under the lever 638. Of the horizontal arm of the lever 638 comes free from the projection 641, and the whole group of segment-shaped stops and the carrier plate 419 are rotated clockwise. The horizontal one The arm of the lever 637 can fall behind the projection 640.

Between the paper pulled from roll 511 through feed roller 526 and the Type segment is a ribbon, as it is e.g. B. is also used in ordinary typewriters, moved (cf. in Fig. 10 the dash-dotted line 645). The ribbon can be fed from spool 646 the coil 647 can be transferred by a pawl 648, which in action with a toothed ring 649 or 650 is brought by an operating lever 651 of T-shape, the one Pin 652 carries to be engaged by a rivet on the end of the ribbon. The pawl 648 is used for Engagement in one of the two ring gears is forced and one is above the center point attached spring 659, whose

other end on a restraint pawl lever 653 is attached, as is common with a ribbon feed device in typewriters. the The pawl 648 can be actuated by an upwardly directed projection 654 on the lever 468 (cf. Fig. 15). When a slide plate 655 is moved to the right by the projection 654 (see. Fig. 10), so it will carry the pawl 648 with it, and the spring 659 becomes the pawl in the position shown bring back and thereby transmit the rotation to the coils 646 and 647, which with the ring gears 649 and 650 are connected in a known manner. The lever 651 can be set in both of its Positions are held by a retaining pawl 656 attached to one end of the Lever 651 in one of the two set positions intervenes (see. Fig. 10).

The operation of the page typewriter according to the invention is the same as that of the strip typewriter. The selection of the characters on the type segment for printing is achieved by optionally operating the slide rails 392 to 396, to rotate the type segment in one of the two directions and to adjust the stops that limit the amount of rotation. The height to which the type segment is raised is also determined by controlled by two slide rails that bring the stops in the path of the type segment and thus its upward movement limit under the action of its operating lever. Furthermore, the page printer is so far same as the strip printer, as the actuation selection by adjusting the rails 400 to 404 and the slide rails 392 to 396. The actuation selection, as previously described in detail, the setting has the selected Actuators and in many cases the locking of other actuators result.

When the line feed rail 576 has been selected by its associated actuator rail, the pressure lock rail 571 and the distance switch-off rail 575 are also actuated and so the Prevents printing and spacing during the line feed.

When the carriage return rail 579 is selected by its associated actuation rail, a the pressure is cut off by the pressure lock bar 571; the distance guide is blocked by the distance release bar 575. The carriage return is effected by removing the pawls 591 and 597 from the teeth of the rack 593, by spring 595 pulling the carriage back to its rightmost position. When choosing the operating rail 404 the numbers and letters are switched under control of the type segment in its uppermost position and at its furthest turn. When this actuation is carried out is, the clearance cut-off rail 575 and the pressure lock rail 571 are operated. Although only two exemplary embodiments of the invention have been described, this can in many respects modified and adapted to other circumstances without departing from the spirit of the invention, which is limited only by the following claims.
