Description

Electric trolley function control for booking machine combinations The invention relates to an electrical trolley function control for booking machine combinations, as required from a calculating, balancing or similar machine and an electrical one Typewriter are electrically interconnected and in which by the typewriter the numerical values or the content entered in the keyboard of the calculating machine can be printed out by computing or storage units.

Well-known modern and large booking machines usually form one unity. You can use a keyboard for typing alpha text as well as number keys exhibit. In addition, numerous function keys are provided with which each Horizontal or rotating movements of the printing roller, machine aisles as required the calculating or balancing works or other operations of individual elements of the machine let trigger.

Such booking machines are extensive and expensive. Also can their capacity is rarely fully utilized, especially by small firms.

There has therefore long been a need for large booking machines to replace high-performance systems that can be combined from individual units.

In the simplest and known way, a booking system can be made up of a Typewriter and a calculating machine are combined to form an output device contains the values entered in the numeric keys, but also the content from storage, arithmetic and balancing units, converts them into electrical signals. This Signals arrive via lines to magnets, which are arranged in the typewriter and drive their numeric keys. Usually this can be done by calling up the digits from the output device of the calculating machine step by step by switching operations done by the step by step advancing carriage of the typewriter triggered and controlled. In this way, for example, with the Typewriter write bills into which, after pressing a function key, the amount determined by the connected calculating or balancing machine is entered will.

Such a simple combination between a writing and a As can easily be seen, calculating machines can only do a limited number of tasks do, because the mere transfer of digits from a calculating machine to the Numeric keys on a typewriter and the gradual advancement of the typewriter cart during the digit transmission is not enough to be able to solve larger to give booking-related tasks.

A combination of a calculating machine has also become known and an electric typewriter, with a control unit between the two Machinery is provided. The functions of the adding machine can be activated by special keys are controlled, which are arranged on the typewriter. Combined with the typewriter a circuit arrangement is also provided, by means of which the Control unit can be controlled according to a predetermined program so that the individual values in accordance with the corresponding columns on the form can be printed out. For correct column registration of tens, hundreds, etc. becomes the usual tab key in connection with the additional switching arrangement used. The tab key can also be operated remotely.

It is true that a carriage movement can be carried out in such a combination trigger in one aggregate electromagnetically from the other aggregate, but is this requires a considerable amount of circuitry. On the other hand, it is Despite this effort not possible, any carriage movements outside of the specified Control program.

But it is about versatility similar to that of large booking machines has long been known, also with known writing devices electrically coupled to one another and balancing, calculating or similar machines must be reached by the car be able to use the typewriter. as required by any keyboard execute triggerable, controlled movements. It is not enough that only either a tabulation movement or a carriage lift can be initiated and carried out.

The present invention has for its object to be an electrical To create trolley function control for booking machine combinations through which various elevator and tabulating movements of the typewriter carriage as desired can be initiated and controlled from both keyboards as required. A special one It is the task of the limbs and elements of the device according to the invention to be constructed and arranged in such a way that they facilitate the sequence of the original functions of the machines do not interfere when they are used on their own.

In particular, the present invention is therefore intended to provide the known machines already existing switching means so with each other and with new, additional switching elements are combined that meet all requirements booking machine combination is created.

Individual machines in which the The switch lock is electromagnetically actuated. -Other electrical ones are also known Typewriters with tab plungers that can be engaged and disengaged electromagnetically. , In a device for remote control of crank rotation and slide displacement of calculators and similar machines, the slide is moved by one place at a time Pair of buttons optionally to the left or right by means of a three-part rack gear mechanism postponed.

By all these known devices, however, only a few Function sequences are triggered electro = magnetically. A variation of the processes or even the control of a large number of car movements is not possible.

To now with booking machine combinations of such existing Aggregates and calculating, balancing and similar machines a large number of booking-related machines To be able to carry out processes = new, it is proposed according to the invention that their electrical Train car function control so that both the key switch and the Tabulator plunger connected to a switching magnet and for switching on and off the car elevator and line switching device each have an additional magnetic switch it is provided that the switching magnet and the magnetic switch are electrically connected to eitre common circuit arrangement are connected in the for the duration of each triggered carriage movement lockable, arranged in the typewriter or calculating machine On switches are located - which are directly or via intermediate links on the release, e.g .: function keys, are connected and coupled in pairs that by actuation only one of these function keys either the windings of both switching magnets or both magnetic switches can be switched in parallel. '.

With this new trolley function control, you can, independently of one pre-determined program, arbitrary carriage movements in both directions Can be initiated and carried out by pressing a button. The associated switching elements are selected by just one button and together for the duration of the process coupled. Complex switching arrangements can be completely avoided according to the invention. The normal, correct writing out of calculation results is also supported by the Typewriter not affected.

The device according to the invention comprises purely mechanical, electromechanical and electromagreic items which are arranged both in the typewriter and in the calculating or balancing machine. The 'electromechanical or electromagnetic elements are linked to one another by conducting verbini boys. The conductive connections between the typewriter and calculating machine are preferably established using multiple plugs and multiple cables. These circuit arrangements on; themselves or their pictorial representations are not. Subject matter of the invention. - - The individual parts of the device in the typewriter So that both the elevator and the tabulation movements of the typewriter car can be controlled from both keyboards, the organs for initiating and stopping the car movements must be connected to electromagnetic actuation means. In order to ensure that these electromagnetic actuating means are switched on and off in the correct column, the device according to the invention provides, in addition to key-operated switches, additional tab-controlled switches known per se. All switching elements of the device according to the invention are designed so that both the typewriter and the calculating machine can be used individually: The FIG. 1 shows, in a schematic arrangement, parts of the typewriter carriage and the elements of the device arranged in it. A paper roller 99, a control rail 100, a toothed rack 95 and a bar 97 for the tabulator stops are arranged on a carriage frame 94. The stops are closely located on the bar, but for example only stops 981 through 985 are shown. The extension 96, which carries the bar 97 for the tab stops, is connected to the carriage frame 94 by means of an intermediate piece. The F i g. 1 shows only the right side of the paper carriage. On the opposite left side there is a corresponding arrangement for supporting the control rail 100, the paper roller 99, the rack 95 and the bar 97 for the tab stops.

The toothed rack 95 works with one arranged on a shaft 82 Gear 83 and thereby with a ratchet wheel located on the same shaft 78 of the switch lock (not shown) and is thus above the shaft 82, one with the ratchet in frictional connection and one on this Disc arranged approach 77 with a break contact 90 in connection.

The tab stops 981 to 985 shown on the bar 97 are arranged at distances from one another which, for example, are the same as the distances from column lines 403 to 407 on a sheet of form. Bar 97 is the tab bar that is found in every typewriter. The stops 981 to 985 shown, as well as the stops not shown, are arranged in a known manner and can be set in the usual manner not shown here.

With the tabulator stops, a tabulator plunger 36 can interact, which is in a slide shoe 37, which is firmly connected to the machine housing. is guided easily slidable. A holder 38 is fastened to the slide shoe 37, at the lower end of which a stop piece 42 is arranged which receives one end of a cylinder spring 41 . The other end of the cylinder spring 41 engages a spring attachment 39 of the tab plunger 36, whereby this tab plunger 36 is always under the force of the spring 41 in its rest position. In this rest position, the tab plunger 36 is in the retracted position and cannot interact with the tab plungers 981 to 985. A stop 40, which in rest positions against the stop member 42 - is applied, limits the downward movement of the Täbulatörstößels 36. The lower end of Tabulatorstößels 36 is provided with a recess 43 which cooperates with a hinge lug 46 of an angle lever 44th The angle lever 44 is rotatably mounted on a rod 45 which is firmly hinged to the lower end of the retaining ring 38.

The angle lever 44 carries a slide pin 29 on its second lever arm, via which an articulated connection is established both to the tab key 30 and to a switching magnet 20 for the tab plunger 36. For connection to the tab key 30, a connecting member 33 is rotatably attached to the pin 29, which is hinged via a pin 34 to the shaft of the tab key 30, which is designed as an angle lever 31. The angle lever 31 rotates around a rod 32 fixedly connected to the housing of the typewriter.

The switching magnet 20 is firmly connected to the housing of the typewriter by means of a fastening plate 21. The winding of the switching magnet 20 is connected to the circuit of the device via the line connections 23 and 24 in a manner which will be described in more detail later.

A connecting member 26, which has an elongated hole 28 at its front end, is movably articulated to the tie rod 25 of the switching magnet 20 by means of a pin 27. The elongated hole 28 cooperates with the pin 29 of the angle lever 44.

A switch bracket 48 is rotatably mounted on the rod 45 fastened to the lower end of the holder 38. The switch bracket 48 is U-shaped. One leg 480 of the switch bracket is located in the immediate vicinity of the lower end of the bracket 38. The second leg 481 of the switch bracket carries the two lugs 482 and 483. The lug 483 acts via a nipple 85 on the normally closed contacts 86 and 87 of one fixed to the - Housing of the typewriter connected break contact 84 a. The operation of the normally closed contact 84 will be described later.

The approach 482 carries a slide pin 19; Via which the switch bracket 48 is in operative connection with a switching magnet 10 for the switch lock. The switching magnet 10 is firmly connected to the housing of the typewriter by means of a fastening plate 11. "The winding of the switching magnet 10 is connected to the electrical circuit of the device via the line connections 13 and 14 in a manner described later is in operative connection with the slide pin 19 of the switch bracket 48.

The foot end of the extension 483 of the switch bracket 48 shows a pin 484 to which a bumper 49 is pivoted so that it can rotate. The bumper 49 establishes the connection between the switch lock (not shown) and the switch bracket 48 .

`As the F i g. 1 shows, the cross strut of the switch bracket 48 is in the pivoting range of the angle lever 44 that every time the tab key 30 is pressed or the switching magnet 20 is energized, the switch bracket 48 is actuated at the same time as the tab plunger 36 =. Thanks to this arrangement, it is possible not only to extend the tab plunger 36 with the tab key 30 as well as by the switching magnet 20, but at the same time also to disengage the switch lock (not shown).

Via the extension 483 of the switch bracket 48, the normally closed contact 84 is opened at the same time each time the angle lever 44 is actuated.

The tab plunger 36 cannot be influenced by the switching magnet 10. The tie rod 15 acts via the connecting member 16 only on the switch bracket 48, so that only the push rod 49 for the switch lock is actuated and the projection 483 is pivoted to open the switch 84.

At the upper end of the carriage frame 94 , the control rail 100 is arranged, which carries various groups of riders that act on plunger-operated switches.

The in the F i g. 1 recognizable tabs are set in the control rail 100 in accordance with the required carriage movements. The tabs shown only as an example correspond to the columns of the form sheet in a manner which will be described in more detail later, and there is also a certain relationship between them and the tab stops on the bar 97.

The riders of the control rail 100 can be adjusted in the usual way and protrude, as shown in FIG. 1 shows, out of the lower surface of the control rail 100 .

Apart from the two tabs 1010 and 1030 on the left side of the control rail 100, the mode of operation of which will be described later, the tabs are in several, for example in four rows. The tabs in all rows are inserted in columns and partly offset by a type division.

Both during tabulation and during an elevator movement of the typewriter carriage (arrow directions, see FIG. 1), the set tabs can come into operative connection with the tappets of their associated switches. The tabs 1051, 1052, 1053, 1054, 1055 of the first row work with the ram 105, the tabs of the second row 1041, 1042, 1043, etc. with the tappet 104, the tabs of the fourth row 1021, 1022, 1023, etc. with the plunger 102 and the tabs of the fifth row 1011, 1012, 1013 etc. together with the plunger 101 . The rider 1030 shown at the left end of the control rail 100 can come into operative connection with the plunger 103 at the beginning of a tabulation movement and at the end of an elevator movement of the typewriter carriage. The rider 1010 works together with the plunger 101 . The tabs of the second row 1041, 1042, 1043 , etc., as will be explained in detail later, have an elongated shape with respect to the directions of movement of the paper carriage. The front edge of the tabs 1010, 1011, 1012, 1013 etc. in the last row is offset by one type division from the front edges of the tabs in the first, third and fourth rows.

The plungers 101 to 105 slide in the vertical direction in slots which are embedded in horizontally and parallel plates 106 and 107. The plungers 101 to 105 are held in their upper rest position by springs (not shown).

As the F i g. 1 shows, each plunger works together with an associated switch. The plunger 105 is assigned to a switch 130. The switch 130 has nipples 131, 132 and 133 and has working contacts 134, 135, 136, 137 and a changeover switch with contacts 138, 139 and 140. The plunger 104 acts on a switch 141 . The contacts of the switch 141 are shown in the open state because the contact plunger 104 according to FIG. 1 is currently in operative connection with tab 1041. In the rest position, the contacts of switch 141 are closed. The switch 141 carries nipples 142, 143 and normally closed contacts 144, 145 and 146,1.47.

The plunger 103 works together via nipples 123 and 126 with a switch 122 which carries normally open contacts 124, 125 and 127, 128.

The plunger 102 actuates working contacts 118, 119 and 120, 121 of a switch 114 via nipples 116 and 117, and the plunger 101 is in operative connection with a switch 110 via nipples 111 and working contacts 112, 113.

As also belonging to the device according to the invention, are shown in FIG. 1 shows a skip key 1 and a switch 8 that interacts with it. The skip key 1 is arranged on the keyboard of the typewriter. Your key shaft 2 is rotatably mounted around a rod 4 fixedly connected to the housing of the typewriter. The key shaft 2 expands downward into a projection 3 which cooperates with the nipple 5 of the switch 8. The switch 8 is firmly connected to the housing of the typewriter, its contacts 6 and 7 are normally open.

Both the tab key 30 and the skip key 1 become by springs 9 and 12, which act on the respective key shaft, in their normal upper rest positions held. The free ends of the springs are fixed to the housing connected to the typewriter.

F i g. 1 further shows a switch 90 which cooperates with the switch lock (not shown) for each movement of the car elevator. A switching wheel 78 of the switching mechanism works together with a friction disk that carries a switching attachment 77. With every backward movement of the ratchet wheel 78, that is, with every lift of the car, the friction disk is carried along by the ratchet wheel 78 in a clockwise direction. The switch attachment 77 strikes a nipple 91 and opens the contacts 92 and 93 of the switch 90. Both lugs are stopped by a bolt 81 fixedly arranged on the frame of the typewriter.

A U-shaped bearing piece 64 is fixedly connected to the machine frame of the typewriter. A slide rod 66, which carries a limiting pin 68 , which holds a spiral spring 67 against the limb 641 under tension, slides in openings in the limbs 641 and 646. The bearing piece 64 lies in the range of motion of a switching attachment 69 so that the slide rod 66 is moved against the force of the spring 67 at each termination of the entire car lift. In Fig. 1, the switching attachment 69 is drawn, for example, in connection with the control rail 100 . It can of course be arranged at any other suitable location on the paper cart. A tab 63 , which acts on nipples 71 and 72 of a switch 70, is riveted to slide rod 66. The switch 70 turns off the carriage elevator. It has the normally open contacts 73 and 74 and the normally closed contacts 75 and 76. The switch 70 can also be switched by a magnet 50 which is fixedly attached to the frame of the typewriter by means of a plate 51. The winding of the magnet is connected to the circuit of the device via connecting lines 53 and 54 in a manner which will be described in more detail later. The tie rod 55 of the magnet 50 is connected via a pin 57 to a connecting member 56 which acts on a double-armed lever 60 via a second pin 59. The lever 60 is rotatably mounted on a rod 61 which is firmly seated on the machine housing. As the F i g. 1 shows, the switch 70 can thus also be switched by the magnet 50.

It must also be mentioned that in the initial division of the paper carriage compared to a column in the booking form, the area of a tab stop that interacts with the Tabulator joint136, compared to about two thirds of the type division the effective surface of the tab plunger is offset.

The arranged in the calculating or balancing machine parts of the invention Device The balancing machine allows three different carriage movements triggers: »skip the convoy«, »limited car recall« and »convoy recall«.

The column skip is a tabulating movement of the typewriter carriage, during which set tab stops are skipped, while the limited carriage recall and the convoy recall are elevator movements of the paper carriage that are stopped either in the writing start position of the alpha text column or in the writing start positions of the booking columns. To initiate each of these movements, three special function keys, a “t) skip key” 150, a “limited car recall” key 165 and a “column recall key” 195 are provided on the keyboard of the balancing machine. They are pressed into the balancing machine as required after entering a numerical value.

The skip key 150 is attached to a normal key shaft 151, to which a bracket 152 is riveted.

The limited carriage return button 165 , like the skip button, is attached to a normal button shaft 166. A bracket 167 is riveted to this key shaft.

An angled switch bracket 172 branches off from bracket 167 and switches the working contacts 177, 178, 179, 180 and 181, 182 of a switch 173 via nipples 174, 175 and 176. The switch 173 is fixedly arranged on the housing of the balancing machine.

In a cross strut of the bracket 167 there is a hole into which one end of a spring 171 engages. The other end of the spring 171 is fixedly connected to the housing of the balancing or calculating machine, so that the bracket 167 and thus the button 165 are normally held in their upper rest position for the limited carriage return.

The bracket 167 carries a locking pin 169 and a switching pin 170 on its long part. The locking pin 169 interacts with a detent 294 of a pawl 293 bent in a U-shape. The pawl 293 is rotatably arranged on the same rod 299 as the pawl 290 belonging to the skip button. The U-shaped bent pawl 293 is under the action of a spring 295, the other end of which is also connected to the rod 321 .

The switching pin 170 interacts with one arm of an angle lever 216 , which is mounted with its U-shaped part on the rod 218. The second arm of the bell crank 216 is engaged with the tie rod of a solenoid 222 in rotatable operative connection, so that the angle lever can be pivoted by the magnet 222 216th A nose 168 is also arranged on the long part of the bracket 167. This nose 168 can also come into operative connection with the switching rod 236 as soon as the button 165 for the limited carriage return is pressed.

The third key on the keyboard of the balancing machine is the key 195 for "return column". Like the keys already described, it is attached to a normal key shaft 196 to which a long switch bracket 198 is riveted.

While the two already described keys 150, 165 each trigger the operation of the calculating machine when actuated, this option is not provided for the key 195 for the callback of the group. An angled switching bracket 202 branches off from bracket 198 , which via nipples 204, 205, 206 and working contacts 207, 208; 209, 210; 211, 212 can come into operative connection with a switch 203 fixedly arranged on the housing of the balancing machine when the button 195 is pressed.

In a cross strut of the bracket 198 there is a hole into which one end of a spring 201 engages. The other end of the spring 201 is firmly connected to the housing of the balancing machine, so that the bracket 198 and thus the button 195 for the column callback 195 are normally held in their upper rest position.

The bracket 198 carries a locking pin 199 and a switching pin 200 on its long part. The locking pin 199 interacts with a detent 297 of a pawl 296 bent in a U-shape. The pawl 296 is rotatably arranged on the rod 299. The U-shaped bent pawl 296 is under the action of a spring 298, the other end of which is connected to the rod 321 .

The switching pin 200 interacts with a switching lever 217 , which is firmly connected to the rod 218 with a fastening pin 223 .

Another switch bracket 224 is attached to the end of the rod 218 with a pin 225 . The switch bracket 224 is in a rotatable operative connection via a switch pin 226 with a push rod 227 , which is connected in a manner not of further interest here to a button 228 for the car elevator.

A deflection bracket 238 is rotatably articulated to the saddle lever 230 via a pin 237 and is connected to a support lever 240 via a pin 239. The U-shaped part of the support lever 240 is rotatably mounted on a bearing rod 241. The bearing rod 241 lies parallel to a rod 260 and is attached to a support arm 246 for the support lever 240. The support arm 246 forms an attachment to the leg 243 of a U-shaped bent saddle lever 242. A leg 243 and a second leg 244 of the saddle lever 242 are rotatably mounted on the rod 260, which is firmly connected at 261 to the frame of the machine. A switch bracket 245 protrudes from the leg 243 and ends in an angled piece.

The other end of the spring 316 engages the hinged armature 317, so that this under the action of the spring is constantly in its position shown in FIG. 2 is held in the rest position shown.

As soon as the magnet 313 is excited, its hinged armature 317 attracts against the force of the spring 316 and pivots the switching arm 318.

A switching arm 302 can be pivoted via an intermediate member 305 which is rotatably articulated on the switching pin 307 . The switching arm 302 is rotatably connected to the intermediate member 305 with a pin 306. The switching arm 302 carries a hub 303 which is fixedly attached to the rod 299 with a pin 304. As a result of the connection between the switching arm 318 of the hinged armature 317 and the switching arm 302 by the intermediate member 305 , each time the hinged armature 317 attracts, the rod 299 is also rotated counterclockwise. In addition to the pawls 290, 293 and 296 already described, the rod 299 carries a U-shaped unlocking member 328 which is fastened to the rod 299 with a hub 327 and a pin 329.

The unlocking member 328 is used to unlock the pawls 290, 293 and 296, while the long leg of the unlocking member 328 limits its clockwise rotation. With this limitation, a nose of the long leg rests on the rod 321 .

The switching bracket 245 of the saddle lever 242 interacts with the contacts of a switch 250 when it is pivoted via the nipples 251, 252 and 253 . The switch 250 is fixedly arranged on the machine housing and has the working contacts 254, 255; 256, 257; 258, 259.

The pivoting of the saddle lever 242 is caused by a switching magnet 280. The magnet 280 is firmly attached to the housing of the machine. The coil of magnet 280 is connected to the circuit of the device via lead terminals 283 and 284 in a manner to be described later. The switching magnet 280 has a yoke 281 to which a hinged armature 285 is rotatably attached. This is under the influence of a spring 287, the other end of which is attached to a pin 288 which sits on the yoke 281.

A switching arm 268 of the hinged armature 285 carries a switching pin 286 which interacts with a switching lever 276 as soon as the magnet 280 is excited. The shift lever 276 is fixedly arranged on a rod 274 by means of a hub 275 and a fastening pin 277. The rod 274 is rotatably supported in the bearings 278 and 279.

On the side opposite the shift lever 276, a shift bracket 270 is fastened on the rod 274, which has a hub 272 and a fastening pin 273. At the front end of the switch bracket 270 there is a switch pin 271 which interacts with the support lever 240 when it is pivoted into its operative position by the deflection bracket 1238 and the switching magnet 280 is energized. The electrical circuit arrangement The F i g. 3 shows the electrical circuit arrangement by which the electromechanical and electromagnetic elements of the device are connected to one another.

The device according to the invention is a self-contained additional device, which, although their elements are distributed over the individual machines, as a uniform circuit is to be considered. It is irrelevant whether and where the multi-core connecting cables branch off between the two machines. These connecting lines have therefore not been particularly emphasized.

On the left of the FIG. 3 shows the switching magnets 10, 20, 341, 342, 50 and 340 already mentioned above, which are located in the typewriter. The skip key 1 is also on the typewriter's keyboard. In the middle of the fig. 3 shows the plunger-actuated switches 110, 114, 122, 141 and 130, while the elements provided in the balancing machine are arranged on the right-hand part of the figure. These include the switching magnet 280, the unlocking magnet 313, the switch 250 and the buttons 150, 165 and 195 with their associated switches 158, 173 and 203.

The switching arrangement is connected to the power supply via terminals 330 and 331 connected. The solenoids 10 and 20 for the switch lock, not shown and for the tab stops 136 (see Fig. 1), together with the relays 341, 342, the magnetic switches 50, 340 and the magnets 280 and 313 directly to a collecting line 370 connected. Power is supplied via switches, their arrangement will be described below.

The switching arrangement for "skipping columns" With "jumping columns", both the typewriter and the balancing machine should trigger a tabulation process in the typewriter car, during which certain tabular stops can be skipped if desired. As the F i g. 1 shows, the two switching magnets 10 and 20 are provided in the typewriter to carry out these switching operations, and the skip key 1 is provided in the typewriter keyboard and the skip key 150 in the balancing machine is provided for actuation. First of all, it will be described how the switching magnets 10 and 20 are controlled from the typewriter when the 3 "column skip" is triggered by key 1. When the button 1 is actuated, it closes the contacts 6 and 7 of the switch 8, as a result of which the switch-on winding 346 of a relay 342 operating in a self-holding circuit is energized. The switch-on circuit is then closed as follows: Terminal 330, contacts 92, 93 of switch 90, contacts 6, 7 of skip button 1, switch-on winding 346 of relay 342, back via line 370 to terminal 331. Relay 342 picks up and closes contacts 347, 348; 349, 350; 351, 352. Of these, 351, 352 are the self-holding contacts. The latching circuit of relay 342 runs as follows: Terminal 330, contacts 92, 93 of switch 90, the closed contacts 343, 344 of switching relay 341, latching contacts 352, 351 of switching relay 342, via self-holding winding 345 and back via line 370 to the Terminal 331.

The circuit for the winding of the relay 341, which is used to interrupt the self-holding circuit for the switching relay 342 , runs via the plunger-operated switches 110 and 141 as follows: Terminal 330, contacts 92, 93 of switch 90, break contacts 146, 147 of switch 141, Working contacts 113, 112 of switch 110, line 369 for winding relay 341, back via line 370 to terminal 331. Switches 141 and 110 are plunger-actuated switches.

In this example, the switching magnet 10 can only be switched by the contacts 349, 350 of the switching relay 342. When the switching relay 342 is energized, the circuit for the switching magnet 10 runs as follows: Terminal 330, contacts 92, 93 of switch 90, relay contacts 350, 349, via the winding of switching magnet 10 and bus line 370 back to terminal 331.

The circuit for the switching magnet 20, which is also closed by the contacts 342, still has the plunger-actuated switch 141 . When relay 342 is energized, the circuit for solenoid 20 is as follows: Terminal 330, contacts 92, 93 of switch 90, normally closed contacts 144, 145 of switch 141, contacts 348, 347 of relay 342, via the winding of solenoid 20 and the bus 370 back to the connection terminal 331. Thus, the winding of the switching magnet 20 can be de-energized by a tab 1041 on the control rail 100 of the typewriter via the switch 141 when the relay 342 is constantly energized. Each time the solenoid 20 is de-energized, as shown in FIG. 1 shows that the tab plunger 36 is pulled out of the active area of the tab stops 981 to 985 as a result of the force of the spring 41.

In the event that the skipping of tab stops is to be triggered by the typewriter trolley from the balancing or calculating machine, the switching magnets 10 and 20 must be actuated by the calculating machine. This is how the circuit diagram according to FIG. 3 shows that the switch 250 is provided, its contacts 254, 255 and 256, 257 parallel to the contacts 347; 348, 349; 350 of the switching relay 342 lie.

As the fig. 2, the switch 250 is always then switched by the magnet 280, if initiated by the skip key 150 of the support lever 240 in the area of action of the switch pin 271 on the switch bracket 270 was panned. The magnet 280 is actuated via the switch 130 excited.

The circuit for the magnet 280 runs as follows: Terminal 330, contacts 92, 93 of switch 90, contacts 86, 87 of switch 84, normally open contacts 136, 137 of switch 130, line 355, via the winding of magnet 280 and busbar 370 back to the terminal 331. The switch 130, which is switched by the plunger 105, also has the normally open contact 134, 135 through which the magnet for the space bar of the typewriter is actuated in a manner not shown here. In addition, a changeover switch with contacts 139, 138 and 140 is provided, which triggers switching processes that are not of interest here.

The switch 250 closes the following circuits: Terminal 330, contacts 92, 93 of switch 90, contacts 254, 255 of switch 250, winding of switching magnet 20 back via bus 370 to terminal 331 and the circuit for switching magnet 10 from the terminal 330, via the contacts 92, 93 of the switch 90, the contacts 256, 257 of the switch 250 to the winding of the switching magnet 10 and from here back via the bus 370 to the terminal 331. Through the contacts 258, 259 of the switch 250 If the switch 158 of the skip button 150 had not been opened, the winding of the magnet 340 would be connected to voltage. The magnet 340 turns on the trolley elevator. However, this will be discussed in the description of the mode of operation.

To unlock the switch 250 and the button 150 is like that F i g. 2 shows that the unlocking magnet 313 is provided. The winding of the Unlocking magnet 313 is parallel to the winding of the relay 341, which the Latching circuit for relay 342 is interrupted. The relay 341 and the unlocking magnet 313 are thus by the same tab on the control rail 100 of the typewriter turned on. The circuit for the unlocking magnet 313 is as follows: Terminal 330, contacts 92 and 93 of switch 90, normally closed contacts 146, 147 des actuated by the plunger 104 switch 141, make contacts 113, 112 of the Plunger 101 actuated switch 110 via line 368, the winding of the magnet 313 and line 370 back to terminal 331.

The interaction of the individual parts just described is described in the paragraph Function explained in detail.

The switching arrangement for the "limited car recall" The "limited Car Recall "is a car elevator movement that has stopped at a desired location will. Since this car elevator movement after entering numeric values into the keyboard the balancing machine is triggered, the associated trigger button »is also more limited Car Recall «165 arranged in the keypad of the balancing machine. this function so cannot be triggered from the typewriter.

For switching the car lift device on and off with line switching the switches that can be switched by the magnets 340 and 50 are provided. Parallel to the switching contacts 334, 335, which are in the typewriter of the car lift button 333 are closed, the contacts 336, 337 are located, which are controlled by the magnet 340 are lockable. Thus, as soon as the magnet 340 is energized, the trolley elevator will run on.

The normally closed contact 75, 76 is in series with the two normally open contacts 334, 335 and 336, 337. This normally closed contact, together with the normally open contacts 73, 74, can, as shown in FIG. 1 can be seen to switch by the magnet 50. As soon as the magnet 50 is excited, the car elevator device switches off with the line switch.

The key 165 for triggering the limited car recall is on the keypad of the balancing machine. As the F i g. 2 shows, the contacts 177, 178; 179, 180 and 181, 182 are closed. The closed contacts 181, 182 of the switch 173 can trigger functions that are not of interest in connection with the present invention.

By actuating the key 165, the circuits for the switch-on magnet 340 and the switch-off magnet 50 of the trolley elevator device are connected in parallel with a line connection. The contacts 179, 180 prepare the circuit for the switch-off magnet as follows: Terminal 330, line 371, connection points 372, 373, contacts 180, 179 of the switch 173 switched by key 165 , line 374, contacts 125, 124 of the plunger 103 switched switch 122, line 366, connection point 375, via the winding of the magnet 50 and the line 370 to the connection terminal 331.

While turning on in the just listed and by the pressure on the key 165 prepared line connection through the tab-operated switch 122 is made, the circuit for the solenoid 340 is as follows Way prepared by the key 165: By the in F i g. 2 shown in more detail The device becomes the lowering lever 240 when the button 165 is pressed brought into the range of motion of the switch pin 271 on the switch arm 270. Only after so that the switching on of the switch 250 has been prepared, by closing it of the rider-operated switch 130, the magnet 280 thus excited close the switch 250. After switch 250 has been closed in the manner just described, proceeds the circuit for the magnet 340 as follows: terminal 330, line 371, Connection points 372, 373, contacts 259, 258 of switch 250, contacts 161, 160 of switch 158, which can be opened by skip key 150, connection point 376, line 367, via the winding of the magnet 340 and the collecting line 370 to Terminal 331.

The switching arrangement for the »convoy recall« The »convoy recall« function is triggered by the balancing machine after an incorrect booking. After pressing the column callback button 195 , the typewriter carriage is brought back by one column width with a line break at the same time. While the keys 165 and 150 each trigger a machine cycle of the balancing machine, which takes place before the movements of the typewriter carriage, the movement of the typewriter carriage can be triggered immediately by pressing the key 195.

Through the contacts 207, 208 and 209, 210 of the switch 203 actuated by the button 195, the circuits for the switch-on magnet 340 and the switch-off magnet 50 are initially connected in parallel after the button is pressed. 210 connection point 376, line 367, coil terminal 330, line 371, connection point 372, contacts 209, of the closing 340 and over the bus 370 to the terminal 331. The circuit for the Abschaltmagneten 50: Here, the circuit passes to the closing solenoid 340 as follows runs as follows: Terminal 330, line 371, terminal 372, terminal 373, contacts 208, 207 of the switch 203 actuated by the button 195, contacts 119, 118 of the switch 114 actuated by the plunger 102 , line 378, terminal 375, via the Winding the magnet 50 and the bus 370 to the Klenune 331.

A cooperation of the arrangement just described is the description the mode of operation.

An account card used, for example, Die F i g. 4 shows an account card that has been used as an example. The head of the account card is designed in the usual way. The column lines 400, 401 to 407 delimit columns that are to be filled with either alpha text or digits. Numbers 400 to 407 will be referred to when describing the mode of operation.

Mode of operation General: The two in FIG. Switches 90 and 84 shown in FIG. 1 permit, as shown in FIG. 3 it can be seen that certain elements of the device according to the invention are switched off when a functional sequence of the typewriter carriage takes place. The switch 90 cooperating with the switch lock, which is opened with every movement of the carriage elevator, switches off all elements which could trigger a tabulation movement of the paper carriage. After the switch 90 has been opened, only the line 371 is connected to the connection terminal 330 .

The switch 84, on the other hand, is actuated every time the switch lock of the typewriter carriage releases it for a tabulation movement. In this case, the magnet 280 is also disconnected from the network, but this happens after the position of the switch 250 has been mechanically locked.

It is first the mode of operation of the device according to the invention after triggering a skip function.

For example, skips are required when in the text column according to FIG. 4 made an entry from the keyboard of the typewriter and the corresponding number entry is made in the credit column target. To do this, after pressing a function key, the direct debit column be skipped. The switch to trigger this function is more advantageous Way arranged in the keyboard of the typewriter.

Another type of skipping must take place when after writing out of an alpha text in the text column, a direct debit should be posted. To Entry of the direct debit in the associated column must then be entered in the credit column be skipped so that the typewriter carriage is in the start typing position the column "Old balance" persists.

However, the device according to the invention is not limited to two skip functions just described. As from the further explanation is shown, the tabs or tab stops can be opened with the appropriate setting also skip several columns in a row.

An alpha text was initially written before the skip function was triggered the skip function is triggered from the keyboard of the typewriter. The typewriter carriage immediately begins the tabulation movement. Was however a numerical value in the keyboard of the balancing machine before the skip function is triggered is entered, then a desired skip function is then used by the associated Key triggered in adding machine keyboard. It must be noted that after pressing the skip key in the calculator, first an operation the balancing machine is triggered, in the course of which the in the keyboard of the calculating machine entered values or the values that are in a memory of the calculating machine can be transferred step by step to the typewriter. Only after The typewriter trolley releases the end of this digit transmission after being driven over the last decade the tabulation process by means of a tab-operated switch out.

Posting a credit after writing the text After the alpha text has been completed, the skip key 1 on the typewriter is pressed. The button closes contacts 6 and 7 of switch B against the force of spring 9. This energizes the switch-on winding of relay 342. Relay 342 picks up and closes its contacts 347, 348; 349, 350 and 351, 352. The contacts 351, 352 close the self-holding circuit of the switching relay 342, whereby the self-holding winding 345 via the contacts 343, 344 of the relay 341 is excited. The switching relay 342 thus holds itself even if the skip key 1 in the typewriter is released.

Voltage is applied directly to switching magnet 20 via contacts 347, 348 of switching relay 342 and switching magnet 10 via contacts 349, 350. Both magnets attract. According to FIG. 1, in which the paper trolley is shown in the trolley position "beginning debit", the switching magnet 20 brings the tab plunger 36 against the action of the spring 41 into an advanced position via its tie rod 25 and the angle lever 44. The switching magnet 10 pivots the switching bracket 48, whereby the push rod 49 is actuated to disengage the switch lock and the contacts 86, 87 of the switch 84 are opened. The switch 84 switches off the circuit 355 for the magnet 280, whereby an excitation of the magnet 280 by the switch 130 and thus incorrect switching are prevented.

The unlocked key lock gives the typewriter cart to tabulate free, the car slides to the left.

Here, as mentioned, the tab plunger 36 is extended and is located in the path of movement of the tab stops 981 to 985. The carriage would therefore normally be stopped when a tab stop 981 to 985 hits the tab plunger 36.

However, before a tab stop strikes the tab plunger 36, a correspondingly set elongate rider 1041 to 1043 of the control rail 100 runs onto the plunger 104 located in its path. The front edge of each tab 1041 to 1043 is set so that it actuates the plunger 104 just before a tab stop 981 to 985 hits the tab plunger 36. The rider, for example 1041, pushes the plunger 104 downwards, whereby the normally closed contacts 144, 145 and 146, 147 are opened. The contacts 144, 145 are in the circuit of the magnet 20. This is de-excited. His tie rod 25 can move to the right following the force of the spring 41. The spring 41 also pulls the tab plunger 36 out of the path of the tab stops 981 to 985 so that the typewriter carriage can slide further to the left without interference. Since the circuit for the switching magnet 10 was not interrupted, the latter remains energized, whereby the switching mechanism of the typewriter remains out of engagement with the switching wheel 78 via the push rod 49. The switch 84 also remains open while the tab plunger is driven over.

When a rider 1041 to 1043 has passed over the plunger 104, the contacts of the switch 141 close again. The switching magnet 20 pulls again and pushes the tabulator push 136, against the force of the spring 41, back into its operative position.

The actuation of the switch 110 by one of the tabs 1011 to 1013 and the closing of its contacts 112, 113 remains ineffective with regard to the unlocking magnet 313 and the relay 341 , because the wide tab 1041 puts the switch 141 in front of that of a tab 1011 to 1013 switchable switch 110 opens.

So that the paper trolley can stop at the tab stop 982, for example, the tab 1042 must not be plugged in. It is therefore in FIG. 1 indicated, but not shown in the extended position. The carriage is accordingly stopped by the tab stop 982. At the same time, the rider 1012 is on its plunger 101, whereby the contacts 112, 113 of the switch 110 are closed. The relay 341 is connected to voltage, picks up and opens its normally closed contact 343, 344. As a result, the self-holding circuit for the switching relay 342 is canceled. The relay 342 drops out and opens its normally open contacts 347, 348; 349, 350 and 351, 352. The solenoids 10 and 20 fall off. The spring 41 pulls the tab plunger 36 back into its rest position, while a spring returns the switch bracket 48 to its starting position. The switch lock comes into engagement with the ratchet wheel 78 again through the push rod 49. Here, the car is allowed to travel a further 2 mm to the left. In this position, a tab stop, as it is at the stop 981 in FIG. 1 is shown, the plunger 36 just run over. The car is in the desired position "start credit column".

Posting a direct debit after writing the text and skipping the credit column. It is assumed that the alpha text between columns 401 and 403 of the contacts according to FIG. 4 is finished. In order to move the typewriter trolley to the starting position of the direct debit column immediately behind line 403 , the tab key 30 in the typewriter is pressed and held down until the trolley is tabulated in the known manner in the "start debit" position. During this time, the normally closed contacts 86 and 87 of the switch 84 are open, so that the rider 1051 passes over the plunger 105 and thus the closing of the contacts 136, 137 of the switch 130 has no effect.

After the typewriter trolley has stopped in the "Start debit column" position, the amount for the direct debit is keyed in in a known manner on the keyboard of the balancing machine. Since in the present case the typewriter car is supposed to skip the credit column after the direct debit has been booked and jump to the initial position of the column "Old balance" (see FIG. 4), the general motor key is not displayed in the after keying in the amount Balancing machine. Hit, but the skip key 150 of the balancing machine pressed.

Here, the pawl 290 is pivoted via the bracket 152 riveted to the key shaft 151 , against the force of the spring 156 and by the locking pin 154. The locking pin 154 runs onto the inclined edge of the pawl 290 . At the end of the movement, the pin 154 comes under the locking lug 291 of the pawl 290, whereby the skip button is locked in its depressed position. In this position, the angled switch bracket 157 acts on the nipple 159 of the switch 158 and opens the contacts 160 and 161. As a result, the line 367 is disconnected from the mains for the duration of the locking of the button 150, even if its contacts are switched on the switch 250 258, 259 close. The line 367 leads to the magnet 340 with which the car elevator device and the line circuit are switched on.

At the same time, the nose 153 of the bracket 152 riveted to the shaft 151 of the button 150 presses on the switching rod 236 of the saddle lever 230. The saddle lever 230 pivots against the force of the spring 229 and counterclockwise around the bearing rod 234 and brings the lowering lever via the pivot bracket 1238 240 in the effective position to the switching pin 271, which is attached to the front end of the switching bracket 270 .

In a known, but not shown manner, the skip key releases 150 a machine cycle of the calculating or balancing machine. This will make the into the keyboard of the arithmetic or. Balancing machine amount entered offset in the usual way in the machine, on the recording medium of the arithmetic or. The balancing machine is printed out and transferred to the machine's electrical storage system. The stored values are then transferred to the in a known manner Typewriter instead, with the digits starting from the highest decade sensed in the memory and, for example, on an account sheet (Fig. 4) in the typewriter trolley to be written out.

As is well known, the typewriter trolley moves step by step Step to the left and run at the end of the transfer, i.e. after the lowest decade in the direct debit column, with tab 1052 on the pestle 105 on.

When the rider 1052 of the control rail 100 runs onto the plunger 105 , the switch 130 is actuated. The normally open contacts 134, 135 and 137 close while the contact 139 switches from the contact 138 to the contact 140. By closing the contacts 134, 135, the magnet (not shown) for the space bar in the typewriter is excited, so that the carriage is transported by one type of division and reaches the position "start credit column".

The contacts 136, 137 apply the line 355 and thus the magnet 280 to voltage. Its hinged armature 285 pulls against the force of the spring 287 and pivots the switching arm 268 counterclockwise. The switch pin 286 at the front end of the switch arm 268 pivots the switch lever 276 clockwise, whereby the switch bracket 270 is actuated via the rod 274. The switching pin 271 strikes the previously set support lever 240 and presses it down. As a result, the saddle lever 242, 243, 244 is pivoted clockwise. The switch bracket 245 articulated on the bar] 243 closes the contacts 254, 255 via the nipples 251, 252 and 253; 256, 257 and 258, 259 of switch 250.

While the pivoting movement of the saddle lever 242, 243, 244 against the force of the spring 265 is running, the saddle lever 308, which is under the action of the spring 312, has been pivoted so that a locking lug on the latch 309 via the latching pin 267 on the leg 244 of the saddle lever 242 sets. Thus, the saddle lever 242, 243, 244 is locked in its switching position and the switch 250 is locked in the closed state. The magnet 280 became de-energized again immediately after the switching process and dropped out.

The closing of the contacts 258, 259 remains, as shown in FIG. 3 and, as already described, ineffective because the contacts 160, 161 of the switch 158 had previously been opened by the skip key 150.

Contacts 254, 255 and 256, 257 of switch 250 apply voltage to the windings of switching magnets 10 and 20. The associated circuits were explained in detail in the description.

As has already been described in the previous section, the switching magnet 20 brings the tab plunger 36 via the angle lever 44, against the force of the spring 41, into the stop position. The switching magnet 10 brings the switching mechanism of the typewriter out of engagement with the switching wheel 78 via the switching bracket 48 and the bumper 49, whereby a tabulating movement of the paper carriage is triggered. The paper carriage slides to the left until a tab stop, such as stop 983, strikes the tab plunger 36 and stops the carriage.

By pivoting the switch bracket 48 , the contacts 86, 87 of the switch 84 were also opened (cf. FIG. 1 and 3). As a result, the actuation of the plunger 105 by one of the riders 1051 to 1055 on the control rail 100 remains ineffective, so that the magnet 280 and the magnet (not shown) for the space bar are not constantly switched. F i g. 1 shows the relative arrangement of the tabs 1011, 1021, 1041 and 1051 on the control rail 100 . These tabs are aligned with the tab stop on the bar 97 so that the rear tab row is accumulated from 1010 to 1013 on the plunger 101 while stopping the carriage by moving a tab stops, for example of the stop 981, against the tappet 36 at the same time the rider 1011th The contacts of the switch 110 are therefore closed in the stop position mentioned. According to FIG. 3, the unlocking magnet 313 is thereby applied to voltage.

The armature 317 of the unlocking magnet 313 attracts and is pivoted against the force of the spring 316, whereby the switching arm 318 on the hinged armature 317 is pivoted counterclockwise. The switching pin 307 strikes the end 289 of the saddle lever 308 and pivots it counterclockwise against the force of the spring 312. As a result, the latch 309 releases the latch pin 267 so that the saddle lever 242, 243, 244 can pivot counterclockwise under the action of the spring 265. As a result of this pivoting, the switch bracket 245 releases the nipples 251, 252, 253 of the switch 250 so that it can open. The pivoting movement of the saddle lever 242, 243, 244 is limited by the stop of the limiting pin 262 on the upper edge of the rectangular cutout 264 in the housing part 263.

By opening the contacts 254, 255; 256, 257 of the switch 250 , the switching magnets 10 and 20 are de-energized and drop off. As already described, the tab plunger 36 is then pulled out of the active area of a tab stop, for example the stop 981, by the spring 41 and the switch mechanism is brought back into operative connection with the ratchet wheel 78 by pulling back the push rod 49. When the key lock engages, as already described, the typewriter carriage moves 2 mm further, so that it reaches the start of writing position in the "Old balance" column.

As shown in FIG. 2, the hinged armature 317 of the unlocking magnet 313 has also pivoted the switching arm 302 via the intermediate member 305, the hub 303 of which is pinned to the rod 299 by means of the pin 304. As a result, the locking member 328, which is also fastened on the rod 299 with the hub 327 and pin 329, is pivoted, as a result of which the pawls 290, 293 and 296 are rotated. In the present case, the locking pin 154 on the bracket 152 of the skip button 150 is released by the latching lug 291. The spring 156 pulls the bracket 152 back into its rest position, in which the skip key of the balancing machine is again in its starting position. The contacts 160, 161 of the switch 158 are closed, and the spring 229 has reset the positioning lever 240 into the starting position.

This means that the paper trolley is skipped from the end of the direct debit column 403 via the credit column 404 to the writing start position 405 of the column "Old balance" ended.

It should also be noted that, as shown in FIG. 2 reveals the same Function can also be triggered by magnet 221. This allows a remote control the calculating machine also with regard to the sequence of the special functions.

The limited carriage return for collective bookings is made after booking of the turnover in the direct debit column or in the credit column of the car Typewriter immediately recalled to the start of writing position of the alpha text column, without having made an entry in one of the balance columns. The following Document is entered in the next line of the text column.

In order to carry out this booking process with a booking machine, consisting of an electrically coupled typewriter and calculator to be able to, a switching arrangement must be provided in the device according to the invention be able to return the typewriter carriage after pressing a special key is carried out from a sales column into the text column. This button »more limited Carriage return «is expediently in the keyboard of the calculating or balancing machine arranged because the "limited carriage return" function is only ever triggered after entering digits into the calculator keyboard.

The "limited carriage return" key 165 can, just like the skip key 150, trigger a machine cycle of the calculating or balancing machine. Therefore, to trigger a "limited carriage return" function after entering the digits not the motor key in the keyboard of the balancing machine, but the special function key "Limited carriage return" pressed.

Here, the pawl 293 is pivoted via the bracket 167 riveted to the shaft 166 of the button 165, against the force of the spring 171 and by the locking pin 169. The locking pin 169 runs onto the inclined edge of the pawl 293. At the end of the movement, the pin 169 comes under the detent 294 of the pawl 293, whereby the button 165 for the limited carriage return is locked in its depressed position.

In this position, the angled switch bracket 172 acts on the nipple 174, 175, 176 of switch 173 and closes contacts 177, 178; 179, 180 and 181, 182. The closing of 181,182 triggers functions that are related do not care with the present invention. The effect of contacts 177, 178 will be described later.

The contacts 179, 180 connect the line 374 to the connection terminal 330, so that the circuit for the switch-off magnet 50 via the normally open contacts 124, 125 of the normally open switch 122 is prepared.

At the same time, the nose 168 of the bracket 167 riveted to the shaft 166 of the button 165 presses the switching pin 236 of the saddle lever 230. The saddle lever 230 pivots against the force of the spring 229 and counterclockwise around the bearing rod 234 and brings the support lever via the pivot bracket 238 240 in the effective position to the switching pin 271, which is attached to the front end of the switching bracket 270 .

In a known manner, but not shown, the key 165 for the “limited carriage return” triggers a machine run of the calculating or balancing machine. This is the in the keyboard of the arithmetic or. The amount entered in the balancing machine is offset in the usual way in the machine, printed out on the recording medium of the calculating or balancing machine and stored in the electrical storage unit of the. Machine transfer. The stored values are then transferred to the typewriter in a known manner, with the digits being sensed from the memory, starting from the highest decade, and being written out, for example, on an account sheet (FIG. 4) in the typewriter trolley. As is well known, the typewriter trolley moves step by step to the left and at the end of the transfer, i.e. after the lowest decade has been printed out in a sales column, one of the tabs 1051 to 1055 hits the pile 1105.

When one of the riders 1051 to 1055 of the control rail 100 hits the plunger 105 , the switch 130 is actuated. The normally open contacts 134, 135 and 136, 137 close while the contact 139 switches from the contact 138 to the contact 140. By closing the contacts 134 , 135 the magnet, not shown, for the space bar in the typewriter is excited. However, as will soon be seen, this remains irrelevant since a carriage elevator movement is initiated.

The contacts 136, 137 apply the line 355 and thus the magnet 280 to voltage. Its hinged armature 285 pulls against the force of the spring 287 and pivots the switching arm 268 counterclockwise. The switch pin 286 at the front end of the switch arm 268 pivots the switch lever 276 clockwise, whereby the switch bracket 270 is actuated via the rod 274. The switching pin 271 strikes the previously set support lever 240 and presses it down. As a result, the saddle lever 242, 243, 244 is pivoted clockwise. The switching bracket 245 hinged to the leg 243 closes the contacts 254, 255 via the nipples 251, 252 and 253; 256, 257 and 258, 259 of switch 250.

While the pivoting movement of the saddle lever 242, 243, 244 against the force of the spring 265 is running, the saddle lever 308, which is under the action of the spring 312 , has been pivoted so that a locking lug on the latch 309 via the latching pin 267 on the leg 244 of the saddle lever 242 sets. Thus, the saddle lever 242, 243, 244 is locked in its switching position and the switch 250 is locked in the closed state. The magnet 280 became de-energized again immediately after the switching process and dropped out.

Through the contacts 258, 259, the line 367 is connected to voltage via the closed contacts 160, 161 of the switch 158 under the skip button 150 and via the connection point 376. This energizes the magnet 340 , which closes the contacts 336, 337 in the circuit of the elevator device for the typewriter trolley. After a carriage return has been performed, the carriage elevator movement begins.

As a result of the reverse movement of the ratchet wheel 78, the shift attachment 77 is at the in FIG. 1 friction wheel, not shown, taken along in the same direction of movement. It strikes against the nipple 91 and opens the contacts 92 and 93 of the key switch switch 90. The movement of the switch attachment 77 is limited by the fact that the nose 80 strikes the bolt 81.

The opening of the contacts 92, 93 of the switch 90 separates the lines 355 and 382 from the terminal 330 , so that the closing of the contacts 254, 255 and 256, 257 with respect to the switching magnets 10 and 20 for the switch lock and the tab plunger 36 remains meaningless.

The return movement of the paper carriage continues until the rider 1030 runs onto the plunger 103. Plunger 103 closes contacts 124; 125 des Switch 122, whereby the magnet 50 via the closed contacts 179,180 of the Switch 173, lines 374, 366 and terminal 375 are connected to voltage will.

Magnet 50 opens contacts 75, 76 in the circuit for the car elevator device, thereby turning it off. The typewriter's carriage stops moving. The tab 1030 is arranged on the control rail 100 so that the car elevator device is parked in correspondence with the start of writing position in the alpha text column.

After the wagon lift device has been parked, the wagon is immediately under the action of the wagon pulling strap and the wagon tension spring, which pull the wagon from right to left. The switching wheel 78 receives a different direction of rotation, the switching attachment 77 releases the switch 90 and the contacts 92, 93 are closed again.

On the control rail 100 , offset by one type division to the left relative to the slider 1030 , the slider 1010 is arranged in the switching area of the plunger 101 . Shortly before the rider 1030 moves onto the plunger 103 and switches off the car elevator device, the rider 1010 has moved onto the plunger 101 and has closed the contacts 112, 113 of the switch 110 . This connects the magnet 313 to the network. As already described, the magnet 313 unlocks the saddle lever 242, 243, 244 - whereby the switch 250 is opened - and the button 165. The lower lever 240 is retracted into its rest position, spring 171 pulls the button 165 upwards, whereby the contacts of the Open switch 173. The typewriter trolley is held in place by the key switch and is in the starting position of the alpha text column.

The convoy recall To correct an incorrect booking, it is necessary the typewriter car to bring back an entire column, but it would be more advantageous Way a line break is performed.

The typewriter cart can be returned in columns for every column of the account card will be necessary. Here, however, assume the case that there was an incorrect posting in the direct debit column, which will be corrected target. Since a wrong booking in a column is always only at the end of a booking In the present case, the car is already in the position »Beginning Credit column «. It must be returned to the initial writing position "Beginning of direct debit" will. There is a special key in the balancing machine to activate this function 195 "Column recall" planned.

When the key 195 is pressed, the one riveted to the key shaft 196 is riveted Bracket 198 moved downward against the force of spring 201. The locking pin runs here 199 on the inclined edge of the pawl 296, making it counterclockwise is pivoted. At the end of this movement, the locking pin 199 is below the nose 297 so that the button 195 is locked in its depressed position.

the contacts 207, 208 on the switch bracket 202 and the nipple 206 and 204,205; 209, 210 and 211, 212 of switch 203 closed. Contacts 207, 208 and 209, 210 connect the circuits for switching magnets 340 (switch on the car elevator device) and 50 (switch off the car elevator device) in parallel. Through the contacts 209, 210 , the winding for the magnet 340 can be connected directly to the mains via the terminal 376 and the line 367 , while the open contacts 118, 119 are still open in the line for the switch-off magnet 50 connected through the contacts 207, 208 of the switch 114 which can be switched by the plunger 102 are located.

As soon as the button 195 is pressed, the magnet 340 attracts and switches on the car elevator device with the line switch via the contacts 336 and 337. As already described, the carriage is pulled to the right, wherein, as explained in detail in the previous section, the switch attachment 77 opens the contacts 92 and 93 of the switch 90.

As a result, and because only the circuit 378 for the magnet 50 via the contacts 118, 119 of the switch 114 has been prepared by the button 195 and the contacts 207, 208 of the switch 203 , the actuation of the switches 130, 141, 110 and 122 remains through the Plungers 105, 104, 101 and 103 have no effect. Only one of the tabs 1021 to 1023 is able to close the circuit 378 via the connecting terminal 375 for the magnet 50 by closing the contacts 118, 119 via the plunger 102 .

As previously described, the magnet 50 opens the contacts 75, 76 and turns off the car elevator. The carriage ends its winding movement and is immediately under the action of the carriage tension spring, which pulls it to the left. The switch 90 closes. However, the car is held in place by the key switch that has not been disengaged.

In this position, the switch 90 also applies voltage to the magnet 313 because the contacts 112, 113 of the switch 110 are closed by one of the tabs 1011 to 1013 via the plunger 101 . The magnet 313 attracts and pivots the hinged armature attached to its 317 switch arm 318 against the force of spring 316 counterclockwise. As a result, the locking member 328 , which takes the pawl 296 with it, is pivoted via the intermediate member 305, the switching arm 302 and the rod 299. The nose 297 releases the locking pin 199 and the button 195 can return to its rest position under the action of the spring 201.

The contacts 207, 208; 209, 210 and 211, 212 of switch 203 open, and magnets 340 and 50 are de-energized.

The carriage is in the starting position of the desired column.

In the event that the balancing machine has a jump carriage, the switching lever 217 pinned to the shaft 218 is pivoted at the same time by pressing the button 195 via the stop pin 200. The switch lever 224, which is also pinned to the shaft 218 , pulls the switch rod 227 and thus the button 228 downwards via the switch pin 226. The key 228 is the well-known vertical key, which causes a line break of the jumping carriage without tabulation.
