On a bearing bracket 433 (Abi) screwed to the bend 375 y (Fig. 16) of the upper part 375 of the calculator front wall by means of screws (not shown). 19), a lever 434 is pivotably mounted on a shoulder screw 435 which, with a mouth 437 incorporated in a bent arm 436, engages around a pin 438, which in turn is riveted into a shoulder 439 of a slide 440. The slide 440 is connected by parts not shown to the known carriage elevator button lever of a Mercedes Addelektra, also not shown. With an arm 441, the lever 434 can act on a pin 442 which is riveted to the front of the lever 253 already described (Figs. 9 and 19). As already described, the lever 246 is pivotably mounted on a bearing pin 245, on which a further lever 443 (FIG. 9) is also pivotably mounted. A bent rod 446 is hinged to an arm 444 of the lever 443 by means of a shoulder screw 445, which with a mouth 447 worked into its lower end comprises a shoulder rivet 448 riveted into the inside of the arm 441 and thereby with the arm 441 of the lever 434 works together.

A rod 450 is articulated to an arm 449 (FIG. 19) of the lever 443 by means of a shoulder rivet 451, which in turn is connected to a lever 453 by means of a shoulder rivet 452. The lever 453 is pivotable at its bearing point 454 about a bearing arranged in a suitable manner in the arithmetic unit and is able to actuate a clutch to be described later by means of a pin 455. Counters to be described later act with fixed control plates 4433 'and 443 "on the nose 443 χ of the lever 443. A switching flap (Fig , includes vertical counter Z 4 equipped with complementary numerals, is arranged laterally immovable on counter Z 4. By means of shoulder screws 461, which are screwed into the side parts 459 and 460, and by means of slots 462 of the bends and 458 of the switching flap 456, the latter is open With a toothed part 463 of the bend 458, the switching flap 456 engages with a toothed segment 464 of a segment lever 465. The segment lever 465 is on an in

The shoulder screw 466 screwed into the side part 460 is pivotably mounted and is in engagement with a toothed arm 467 with a toothed segment 468. The toothed segment 468 is firmly connected by means of a rivet bolt 469 to a cam (not shown) arranged on the inside of the side part 460, both parts by means of of the rivet bolt 469 are rotatably mounted in the side part 460. Said cam is able to work together with the main drive wheel of the lowest point of the counter for the purpose of introducing the volatile one into the complementary numerals of the counter. A further lever 470 together with a bearing piece 471 is riveted to the segment lever 465 by means of rivets 472. On the bearing piece 471, a manual lever 471a is fixed by a screw 471 and, where he c with bends 471 comprises the bearing piece 471st A spring 475 suspended on one hand on a pin 473 riveted into the lever 470 and on the other hand on a threaded stud bolt 474 screwed into the side part 460 holds the segment lever and the parts connected to it in the rest position, which is caused by the lower ends of the slots 462 hitting the screws 461 is conditional. With a nose 476 of the bend 458, the switching flap 456 acts on a nose 477 of a control plate 377 j (Fig. 18) already described above. The control plate 377jr is pressed into bearing eyes 479 and 480 and through bearing eyes 481

a bearing piece 482 passed through axis 483 pivotally mounted. By means of bolts 484, nuts 485 and intermediate rings 486 is the bearing piece 482 on the counter frame fastened, the bolts 484 through corresponding elongated holes in the control plate 494 protrude through. One between the bearing eyes 481 of the bearing piece 482 on the Axis 483 arranged torsion spring 487 influences the control plate 377 j with a nose

⁴ ^ 488 permanently against the bearing piece 482, whereby the rest position of the control plate 377 .y is caused. The clear signal comb 494 is arranged pivotably on the counter by means of bends 495 around screws 496 screwed into the side parts 459 and 460. An angle lever 499 is pivotably mounted on the shoulder screw 491, with an intermediate washer 500 preventing any friction that may arise as a result of the two levers 489 and 499 lying directly apart. The lever is guided onto the threaded stud bolt 474 by means of a slot 501, an intermediate washer 502 holding the levers 489 and 499 at the required distance from one another. The lever 499 is guided further by a shoulder screw 504 that protrudes through a slot 503 and is screwed into the side part 460. A leaf spring 506 is riveted to the lever 499 by means of a rivet 505, and a bolt 507 protruding through the lever 499 is riveted to the upper end which jumps into one of the detent depressions 508 or 509 of the side part 460 for the purpose of locking the lever 499 in or out of action. When the bolt 507 snaps into the detent recess 508, the lever 499 is out of action. By means of a handle button 510, the lever 499 with a stop lug 511 is manually brought into or out of the operative position to a stop 512 attached to the already described rail 440 (FIG. 19).

A lever 514 is located on a screw 513 screwed into the side part 460 pivotally arranged. By means of one riveted to one in the lever 514 Pin 515 and, on the other hand, suspended from a pin 516 riveted into the side part 460 Spring 517 is the lever 514 with a bent nose 518 permanently against the upper Cover plate 519 of the counter Z 4 pulled, whereby the rest position of the lever 514 is conditional. When the lever 470 is actuated, it cooperates with its pin 473 the end 520 of the lever 514 together. A Part 521 attached to the center pointer, not shown, acts during the carriage movement onto the roof-shaped bend 522.

On the main drive axis 365 already described, there is also the one already described Drive wheel 367 attached to another drive wheel 531 (Fig. 21). aside from that two further drive wheels 532 and 533 cannot be moved laterally, but can be rotated loosely arranged on the axis 365, which engages with clutch teeth 534 and 535, respectively Coupling teeth 536 and 537 one laterally displaceable, but non-rotatable on the axis 365 arranged. Coupling sleeve 538 can be brought. By means of the next above-described lever 453, which with its pin 455 in a groove 539 of the coupling sleeve 538 engages, the latter is optionally controlled.

Four vertical counters arranged on the machine Z ι to Z 4 (Fig. 21 to 25 and 20) can, as described later, be brought into action for the drive wheels 367 and 531 to 533, with the already described control plates 443 y or 443 ζ of the counters Z 1 and Z 2 influence the lever 443 and thereby control the coupling sleeve 538 optionally.

The operation of the device will now be described below, to which Purpose it is assumed that the

IO

Booking entries can be made according to the form shown in Fig. 29 should.

For this purpose, the counters Z 1 to Z 4 (Fig. 21 to 25) are initially in a known manner in accordance with columns I to IV (Fig. 29) of the form on the ones not shown Put on paper trolleys and adjust the tabs assigned to them. Then will the carriage by hand using the carriage release lever or by actuating the not shown car lift button lever automatically brought into the extreme right position.

Now that the form F (Fig. 29) ¹ S has been clamped in the paper trolley and brought into the writing position with the first line Zi , the hundred key T 1 (Fig. 1) of the decimal tab: corresponding to the value 153.42 in column I of form F is depressed , after which the paper carriage in a known manner receives a leftward movement and thereby with the hundreds digit of the column I of the form F (Fig. 29) in the writing position and with the associated \ ^r ertikalzählwerk Z 1 (Fig. 21) is brought into computing location.

The counters Z 1 to Z 4 assume the position shown in FIG. When the counters Z 1 to Z 4 enter this position, the counter Zi acts with the control plate 443 y (Figs. 19, 21 and 22) on the nose 443 χ of the lever 443 and pivots the latter counterclockwise around the bearing 245 whereby the lever 453 is pivoted about the bearing 454 in a clockwise direction. This movement is also followed by the coupling sleeve 538 and assumes the position shown in Fig. 21, in which it is not coupled to any of the drive wheels 532 and 533, so that it is not involved in a rotary movement of the main drive axis 365, i.e. in a calculation process take part. Therefore, only the drive wheels 367 and 531 fastened on the axle 365 and thus only the counters Z 1 and Z 4 can take part in the arithmetic process to be described later. Likewise, the vertical counter Zi acts with its control plate 250 (Figs. 9 and 22) on the nose 248 of the lever 246 and pivots it counterclockwise around the bearing pin 245, whereby the slide 270 influences in the direction of arrow a (Fig. 9) will. The slide 270 comes with its tab 275 out of action against the nose 276 of the unlocking slide 176, whereby the lock 275 is canceled, so that the unlocking slide 176 is released for the downward movement to be described later.

The lever 253 also takes part in the movement of the lever 246 and is displaced upwards against the action of the spring 267. This movement is followed by the action of the spring 261 β, the parts 259 and 261, whereby the lock 261 .r, 264 x (Fig. 9) is made ineffective.

Since the target amount 153.42 of column I of form F (Fig. 29) is in the counter Z 1. So if a plus value is to be introduced, the control plate 274 (Figs. 22 and 13) is set to addition, so that the pipe lever 37 (7 is not influenced, but remains in the rest position. In this position of the roller lever 372 q the drive shaft 365 and thus the drive wheels 367 and 531 prepared for additive computing.

Now the 1 of the value 153.42 * is brought into the vertical counter Z ι by hitting the arithmetic key R corresponding to the number 1 (Fig. 1) and at the same time printed in column I of the form F (Fig. 29), whereby play the following operations:

When pressing the aforementioned arithmetic key. /? the lever 207 (Figs. 4 and 5) is pivoted clockwise about its bearing axis 205. The arm 210 is pivoted out of the active position to the nose 211 of the pawl 104, so that the latter is pivoted under the influence of the tensioned spring 214 (Fig. 5) clockwise around the bearing screw 107 and thereby with the coupling nose 212 in the one just opposite it Gap of the clutch wheel 97 occurs. This establishes the connection between the drive shaft 92, which continuously rotates in the direction of arrow b (Figs. 4 and 5), and the coupling element 95, so that the coupling element 95 and thus also the coupling disks 110 and 112 participate in the rotation in the direction of arrow &. Since the slide 176 with the roller 170 of the articulated lever 172 by spring force against the sloping curve extension 1093; of the cam part 109 is pulled, the parts 172 and 176 are affected immediately, whereby the lever 172 swings clockwise around the bearing screw 121 (Fig. 5 a), no while the unlocking slide 176 a downward movement in the direction of arrow c (Fig. 4 and 5) obtained, which was made possible by the above-described lifting of the lock 275, 276, (Fig. 9). During the aforementioned downward movement of the unlocking slide 176, the parts of the arithmetic unit and counter are unlocked by pivoting the axis 87 (Fig. I, 3, 11, 13, 14 and 15) clockwise and thus prepared for the arithmetic process. Due to the relatively high spring force through which

the unlocking slide 176 with the roller 170 against the sloping part of the curve 1093 » is pulled, it can happen that the axis 92 one the normal number of revolutions of the axis 92 or the motor shaft results in an acceleration exceeding. To avoid this, the following is Arranged braking mechanism described.

ίο Immediately at the beginning of the rotation of the cam element 95, the pin 202 (Fig. 5 and 6) of the screw 203 acts on the slide 196 and moves it against the action of the spring 200 (Fig. 4 and 6) in the direction of arrow d (Fig. 6), in order to make it jump off the pin 202 after a partial rotation of the cam element 95, which corresponds to the sloping cam part 1093 ', whereupon it is moved back under the action of the spring 200 in the opposite direction of the arrow d until it is with the edge 197 χ of its stop piece 197 strikes the surface 201 of the bearing part 192. The accelerating effect of the spring of the unlocking slide 176 is thus compensated here by the braking effect of the spring of the brake slide 196.

At the same time, the pin 202 gives the end 204 of the lever 206 (FIGS. 5 and 6) iiei, whereby a lock (not shown) for the depressed arithmetic key comes into effect.

By pivoting the axis 87 in the clockwise direction, as described above the lever 84 (Fig. 1 and 3) -activated in the same sense, with this on the arm 83 of the lever 74 acts and thereby the latter in the opposite Swiveled around the bearing 78 counter to the action of the spring 82 in the clockwise direction. The arm 73 with its locking nose 72 comes out of action against the locking tab 71 of the lever 68, whereby the lever 68 and its associated parts for later Position to be described are unlocked.

Furthermore, by pivoting the axis 87, the locking lever 167 (Figs. 4 and 7) is pivoted clockwise so that the locking slide 152 of the counting slide 134 can move freely past the locking lever 167 during the downward movement of the counting slide 134 to be described later . Levers 350 (Fig. 11, 13, 14 and 15) and 371 ^ (Fig. 11 and 13) are pivoted clockwise with axis 87. This movement is followed by the alignment tooth 359 under the influence of the spring 371, whereby it, guided on the axis 365 in the direction of arrow e (Figs. 11 and 13 to 15), is moved downwards and thereby disengages from the main drive wheels H opposite it (Fig. 14 and 15 ) of counter Z 1 comes. When the unlocking slide 176 is moved downwards, the lever 216 which is in drive connection with the slide 176 (Fig. 8j) is also moved. The pin 229 is pulled away from under the nose 230, after which the angle lever 232 is pivoted clockwise by the tensioned spring 235 about the bearing screw 233 and pulled against the stop pin 234. The nose 230 of the lever 232 lies in front of the pin 229 of the lever 217 and holds the lever 217 in the swiveled-out position. The pin 239 has also been moved with the lever 217, whereby the coupling gear 241 is displaced on the axis 242 in the direction of the arrow / and with the counting sector 55 (Fig. 1 and 2) is brought into engagement, in this position the clutch gearwheel is held, since according to the preceding also yes the angle lever 217 is held in its pivoted position.

After a partial rotation of the cam element 95 (Figs. 4 and 5), the roller 170 hits the central cam part 109 g of the cam part 109, whereby the downward movement of the unlocking slide is limited. During the further rotary movement of the cam element 95, the rising cam part 102 χ of the cam part 102 acts on the roller 117 of the lever 119 after the roller 108 has already released the arm 132 of the lever 119 during the previous rotary movement of the cam element 95 without closing it influence. Here, the lever 119 is now pivoted counter to the action of the spring 131 in a clockwise direction on the screw 121. This movement is also followed by the parts 136 and 141, the lever 141 also being pivoted about the bearing screw 143 in a clockwise direction. This movement is also followed by the counter slide 134 (FIGS. 4, 5 and 7), which is flexibly connected to the lever 141 by the spring 148, which is moved downwards in the direction of the arrow "c (FIGS. 4, 5 and 7). As above described, the locking slide 152 (Fig. 7) passes the locking lever 167. The counting slide 134 acts when going down with the inclined slot 150 (Fig. 4 and 7) on the bolt 55 a of the counting sector 55 (Fig. 2) During this work process, this value 1 is also entered into counter Z 1 in accordance with the pressed arithmetic key.

brought, where it appears in the display window F ι (Fig. 21) of this counter.

The pivoting of the lever 119 possible through the curve part 102 corresponds a downward movement of the counter slide 134, which corresponds to a value of 10 Pivoting of the counting sector 55 corresponds. So the counting sector 55 performs one Pivoting movement that corresponds to a value below the value 10, so can the counter slide 134 does not quite follow the pivoting movement of the lever 119. He will rather, stopped earlier by the slot 150, while then the lever 119 is still swings out further, against the action of the spring 148 (Figs. 4 and 5), wherein the lever 119 with its slot 133 on the rivet 135 of the counter slide 134 is performed.

If, during the further rotary movement of the cam element 95, the cam disc no (Figs. 4 and 5) with its sloping part no.r comes opposite the roller 179 of the lever 178, the parts 179, 178, 58 (Fig. 2), 68 follow , 56, 57, 51, S3 and 52 of the tensioned spring 59, whereby they are pivoted clockwise with the axis 58. The bar 52 acts on the nose 61 of the number key lever 10 corresponding to the value 1 and depresses it, causing the type lever 67 assigned to the value 1 to stop in a known manner via the parts 63, 64, 66 and 65 (Fig. 1) is brought. As a result, the 1 of the value 153.42 entered in the counter Z 1 is printed in column I of form F (Fig. 29).

When the struck type lever falls back, the Switch lock triggered to actuate a carriage step.

At the same time, the cam disk 112 begins with its rising part ii2.r (Fig. 4 and 5 ') to act on the .Hebel 182, which is pivoted in the counterclockwise direction about the bearing screw 185 and thereby the rod 188 a shift in Arrow direction g (Fig. 4 and 5). Now, through the interaction of the cam part 109 s (Fig. 4 and 5), the unlocking slide 176 is moved back against its spring 176 a so far that the unlocking shaft 87 (Fig. I, 3, 4, 7, 11 and 13 to 15) in the opposite direction Is moved back clockwise to the starting position. At the same time, of course, the locking lever 167 has also returned to the starting position shown in FIGS. 4 and 7.

Likewise, the lever 84 is the return movement of the axis 87 in the starting position (Fig. 3) followed, so that the lever 74. following the tensioned spring 82, with the lower The end of his arm 73 is pulled against the tab 71 of the pivoted lever 68.

Likewise, with the unlocking shaft 87, the lever 350 (Fig. 11, 13, 14 and 15) and the lever 371 p (Fig. 11 and 13) have returned to the starting position, the alignment tooth 359 being influenced by the bend 371 -r and against it the action of the spring 371 is returned to the starting position in the opposite direction of arrow c.

In the meantime, due to the interaction of the rising cam part 1103 (FIGS. 4 and 5) of the cam disk 110 with the roller 179 ″, the parts 179, 178, 58, 68, 56, 57, 51, 53 and 52 are counter to the action of the spring 59 returned to its initial position shown in Fig. 1 and 2, the tab 71 of the lever 68 slides along the lower end of the arm 73 to the end of the return movement, the lever 74 with the locking lug J2, the tensioned spring 82 following, under the locking tabs 71 of the lever 68 to let jump.

With the further rotation of the cam element 95, the unlocking slide 176 is moved back upward against the direction of arrow c by the interaction of the rising cam part loqp (Figs. 4 and 5) of the cam part 109 with the roller 170. Here, the slide 176 acts with its nose 243 (Fig. 8) against the arm 231 of the angle lever 232 and pivots it counterclockwise around the bearing screw 233 against the action of the spring 235. The nose 230 releases the pin 229 so that the angle lever 217 is moved back clockwise around the bearing 224 under the action of the tensioned spring 225 and thus moves the clutch gear wheel 241 in the opposite direction of the arrow / (Fig. 8). The clutch gear wheel is disengaged from the counting sector 55 (Fig. Ι and 2). At the end of this further return movement of the slide 176, it acts with its extension 244 from below against the arm 220 of the angle lever no 217 and brings it, if the spring 225 has not overcome the flank friction arising between the teeth of the clutch gear 241 and the teeth of the counting sector 55 , inevitably back to the position shown in Fig. 8.

With the further rotary movement of the cam element 95, the lever 119 is through Cooperation of its roll 117 with the sloping part 1023 '(Figs. 4 and 5) of the iao Curve part 102, the tensioned spring 131 following, counterclockwise

pivoted and moved back to the starting position. At the end of this return movement or at the end of the rotary movement of the cam element 95, the roller io8 acts from below against the arm 132 of the lever 119, whereby the latter is inevitably returned to its original position if it falls below the Influence of the spring 131 on the curve part 102 does not follow. Via the rivet and slot connection

135) ^X 33, the counter slide 134 is also inevitably moved back up to the starting position. At the same time, of course, the parts 139 and 141 are also moved back to the starting position. Here, the locking slide 152 slides with the beveled front surface 165 χ (Fig. 7) along the slope 166 χ of the lower part of the locking lever 167, being displaced against the action of the spring 164 in the direction of arrow h (Fig. 7) After the slide 134 has reached its starting position, follow the tensioned spring 164 in the opposite direction of the arrow h to the starting position, in which it is in the operative position with its nose 165 in relation to the nose r66 of the locking lever 167.

In the meantime, the cam disk 112 with its sloping part 112 y (FIGS. 4 and 5) has come opposite the lever 182, so that the lever 182 and the rod 188 and the parts actuated thereby can return to the starting position.

Furthermore, at the end of the revolution of the cam element 95, the roller 170 follows from the highest point of the cam part 109 to the sloping part 109 y, namely up to the position shown in FIGS. The slide 176 makes a slight downward movement again and thereby returns to the final starting position.

In the same way, the cam element 95 acts with the pin at the end of this revolution 202 of the screw 203 onto the end 204 of the lever 206 (Fig. 6) and swivels it first in the counterclockwise direction around axis 205, then around it in the starting position to let strike the pin 202. This is a not shown The lock for the pressed arithmetic key released.

At the same time, the pin 202 of the screw 203 pushes the slide 196 (Fig. 6) back against the action of the spring 200 somewhat in the direction of arrow d into the starting position, in which the stop 197λ, 20i is canceled and the slide 196 is permanently against the pin 202 of the screw 203 (Fig. 6) is pulled. -

In the meantime, the carriage step, which was triggered, as described above, has ended, so that the paper carriage is now in the arithmetic position with the next lower position of the counter Z 1.

After only about half a revolution of the cam element 95, the roller 108 acts on the arm 215 of the lever 207 and swivels it counterclockwise about the axis 205 back to the starting position, in which he is with the arm 210 in the operative position to the nose 211 of the coupling pawl 104 stands.

As a result, at the end of the revolution of the cam element 95, the coupling pawl 104 (Fig. 5) hits the arm 210 of the lever 207 with the nose 211 and thereby swivels counterclockwise about the bearing screw 105 counter to the action of the spring 214. In the process, the coupling pawl 104 with the nose 212 disengages from the coupling wheel 97, so that the cam element 95 no longer takes part in the further rotary movement of the drive shaft 92. If, for example, a calculation key R (Fig. 1) is pressed when no counter is in the arithmetic position, that is, if the lever 246 (Fig. 9) is not influenced by the control plates 250, the lever 253 and the parts 268 connected to it remain, 270 in the rest position, in which these parts are held under the action of the spring 267 by striking the end of the slot 274 against the shoulder screw 273. In this. The slider 270 is in the locked position with its tab 275 under the locking lug 276 of the unlocking slider 176. If the unlocking slider 176 is now moved downward in the manner described above by the rotary movement of the cam element 95 triggered when the arithmetic key R is actuated, it is also moved downwards his nose 276 is immediately suspended from the tab 275 of the slide 270 and is thereby prevented from moving downwards.

By blocking the downward movement of the slide 176, the blocking shaft 87 (Figs. 9, 1, 3, 4, 7, 11 and 13 to 15) and thus the levers 84 (Figs. 1 and 3), 167 (Fig. 4 and 7) and 350 (Fig. ix and 13) prevented from pivoting. As a result, the lever 74 (FIG. 3) is not actuated either, so that the lock 71, 72 is not released either, and thus an interaction of the writing bar 52 with the lugs 61 of the number key lever 10 is not possible. So there can be no type stop.

According to the preceding, the lever 167 (Figs. 4 and 7) is not swiveled out either been. Since "but the lever 119 in the described When the cam element 95 is actuated, the counter slide 134 also wants to follow the movement and its downward movement execute what. however not possible

is borrowed because the counter slide 134 with the nose 165 of the locking slide 152 on the nose 166 of the locking lever 167 is suspended. So there can be no counting process. During the rotation of the cam element 95, only parts 119, 139 and 141 moved by the curve part 102, against the action of springs 131 and 148.

The cam part 109 and the cam disk 110 take part in the rotation of the cam element 95 part without influencing the parts assigned to them.

The previously described lock 165, 166 (Fig. 7) also comes into effect, if a counter is in the arithmetic position and the locking shaft for some reason, for example in that the lever, not shown, for actuating the counter locking lever has not yet come out of action for the fixed comma block of the counter, while the curve element 95 'has already been triggered for the calculation of the next digit. This is mainly true for the automatic total move. This will cause computational errors and damage avoided in the calculator and counter.

In the same way as the I of the value 153.42 was entered into the counter Z 1 by pressing the unit arithmetic key R and printed in the corresponding column I of the form F (Fig. 29), the other numbers of the stated value are entered through Pressing the arithmetic keys R assigned to them are introduced into the counter Z 1 and written down in column I of the form. The previously described work processes are repeated, whereby the value 153.42 is displayed in the display window F ι (Fig. 21) and at the same time written down in column I of the form F (Fig. 29). At the same time, the value 153.42 has also been entered by the drive wheel 531 into the balance counter Z 4 (Fig. 21J) and is displayed in this in the display window F 2, ie in the positive set of numerical rollers.

Now there is no value to be entered in column II of form F (Fig. 29) is, any, for example also the hundred tab key of the not shown Decimal tab depressed. With the carriage left movement triggered by this the paper trolley with the counters Z ι to Z 4 comes to that shown in Fig. 26 Position in which the counters Z 2 to Z 4 in the effective position to the drive wheels 367, 532 and 533 stand, while form F (Fig. 29) with column II is in the writing position stands.

In the case of the left-hand movement of the carriage described above, the values from the counter Z 1 for the preparation of the computing process controlled mechanisms released, whereby they return to their original position.

At the same time when the counter Z 2 runs in, the following Mechanisms operated:

The lever 443 is hereby influenced by the control plate 443 s (Figs. 23 and 26), whereby the drive wheel 533 is coupled to the axle 365 by the sleeve 538.

The control plate 250 acts again in the manner previously described on the Lever 246 (Fig. 9).

The control plate 274 (Fig. 23) is set to subtraction in accordance with the credit items to be entered in column II, i.e. negative values, and acts on the roller sweeper 372 q (Fig. 13), which causes the arithmetic unit to be described later Subtraction is reversed.

Since no entry has to be made in column II, the value is now 264.53 Corresponding hundred key of the decimal tab is depressed, causing the carriage with the counters Z 1 to Z 4 comes into the position shown in Fig. 27, in which the Counters Z 3 and Z 4 are in action for the drive wheels 367 and 532, while Form F with column III is in the writing position.

The Z 2 counter controls the preparation of the calculation process Parts released again, whereby they return to the starting position. By running in the counter Z 3, the one Is empty, the following mechanisms are used to prepare the arithmetic process:

The lever 443 is not influenced by the counter Z 3, so that this, the Following the effect of a spring, not shown, into its position of rest according to Fig. 27, in which the drive wheel 532 is coupled to the coupling sleeve 538 and thus to the axle 365. The counter Z 3 also has the control plate 250, with which it acts on the lever 246 and thus the lock 275, 276 (Fig.9) makes ineffective in the manner already described.

Furthermore, the counter Z 3 acts here with the control plate 3/7 / on the nose 377 of the Lever 376 (Fig. 18 and 2) and thus on parts 385, 388, 394, 398 and 405 and pivots this against the action of the spring 382, without any further influence to have the device.

The control plate 274 is omitted here.

sen so that the roller lever 372 does not affect # and the arithmetic unit remains switched to addition.

Now the value 264.53 is written down in column III of form F (Fig. 29) by hitting the corresponding arithmetic keys R , which is done in the manner described above *. This value is not transferred to the counter Z 3,

to because this is an empty work after the previous one. However, it is transmitted via the drive wheel 532 to the counter Z 4 ·, namely additively in accordance with the presetting. The value becomes 264.53. 153.42 is added to the value displayed in the counter Z 4, so that the value 417.95 is now displayed in the display window F 2 (Fig. 21) of the counter Z 4.
Then the hundred-tabulator key of the decimal tabulator corresponding to the value 417.95 is pressed, whereby the paper trolley with the counters Z 1 to Z 4 is brought into the position shown in Fig. 28, in which the counter Z 4 is in effective position in relation to the drive wheel 367, while Form F (Fig. 29) with column IV is in the writing position. When the car moves to the left, the mechanisms operated by the counter Z 3 for preparing the arithmetic process are released, and they return to the starting position.

When the counter Z4 starts running, the following mechanisms are activated:

The lever 443 is here also not influenced, so that it is in the previously described The rest position remains in which the drive wheel 532 is coupled to the axle 365. This has no other here ■ Influence, since the mentioned drive wheel is not in effect for any of the counters.

The control plate 250 of the counter Z 4 also acts on the lever 246 (Fig. 25), whereby the lock 275, 276 (Fig. 9) is unlocked in the manner already described. The counter Z 4 with the control plate 377. $ ■ (Fig. 25) swings out the roller lever 3725 (Fig. 13) clockwise. About the parts 372 n, 3721, 372 h and 372 c, which participate in the movement of the lever 372 q , the lever

372 and thus the axis 332 and the lever

373 pivoted in the counterclockwise direction. By pivoting the lever 373, the arithmetic unit is prepared for the subtractive arithmetic process. With the axis 332 (Fig. 13), the lever 336 is also pivoted in the counterclockwise direction, whereby the rod 339 and thus also the lever 350 are displaced in the direction of arrow i (Figs. 11 and 13). The end 355 of the pin 355 disengages from the slot 357 of the bend 358 (FIG. 15) of the alignment tooth 359 and its end 360 engages the slot 361 of the bend 362 of the alignment tooth 359.

At the same time, the counter Z 4 acts with the control plate 282 χ (Fig. 25 and 12) on the nose 282 of the lever 281 and pivots the latter in a clockwise direction around the bearing screw 280 (Fig. 12). The parts 287, 291, 297 and 307 take part in this movement against the action of the spring 303, the lever 297 with the driver 307 being pivoted about the bearing screw 360 in the counterclockwise direction. The driver 307 comes with its nose 307λ? except for effective position to the nose 413 of the slide 414 (Fig. 12, 17 and 18).

Now the value 417.95 stored in the counter Z4 is written out of this and written down in column IV of the form F (Fig. 29), which is effected as follows by pressing the ^ F key T (Fig. 1, 2 and 18) will:

When the .SF button T (Fig. 2) is depressed, the button lever 47 is pivoted clockwise about the axis 46, the slide 34 being displaced in the direction of arrow k (Fig. 1 and 2) and the lever 20 with the axis 25 and the lever 21 is pivoted clockwise in the bearings 29 and 30. The curved slots 18 and 19 act on the pins 17 in such a way that the bearing brackets 12 and 13 with the bearing rail 6 and its axis 4 are pivoted in the bearings 2 in the counterclockwise direction. This movement is followed with the bearing axis 8 by the number key lever 10, whereby they are displaced in the opposite direction of the arrow k. This shifting of the number key lever 10 with its lugs 61 has the following purpose: The bar 52, which interacts with the lugs 61 of the key lever 10 to operate the latter, is caused by the swiveling of the counting sector 55 over the parts 54, 53, 51 during the arithmetic process to the nose 61 of that key lever 10, which corresponds to the value to be written out, brought into effect. Since the swiveling out of the counting sector is not limited by hitting a fixed, adjustable stop, but rather by hitting the ten switching cams of the counter drive wheels, the unavoidable gear backlash arising in the counter is over the counting sector 35 and the parts 48, 54, 50, 53 and 51 transferred to a larger extent on the bar 52, whereby a reliable interaction of the last

teren with the lugs 61 of the typing number key lever io is endangered. To avoid this, the key levers are io at Sum move moved forward in the manner described above.

When the SF button Γ is depressed and the lever 47 is pivoted, the latter acts with its arm 47 χ (Fig. Ι and 2) on the lever 420 (Fig. 18) and pivots it counterclockwise around the bearing screw 421. At this movement takes part the slide 414 (Fig. 10, 12 and 18), whereby it is moved in the direction of the arrow m . Here, the lever 425 is also influenced and pivoted counterclockwise around the bearing screw 427, with its stop piece 432 (Fig. 18) coming under the bend 362 of the aligning tooth 359 in order to be used as a support for the aligning tooth 359, as will be described later to serve.

Furthermore, when the SV button T (Figs. 1 and 2) is actuated, the lever 207 (Fig. S) would pivot clockwise about the axis 205. The mechanisms already described above are operated, whereby the value stored in counter Z 4 W ^T ert 417.95 places automatically from the counter Z 4 brought out and at the same time of the form F is written in the column IV.

When the lever 350 is swiveled out (Figs. 14 and 13J with the axis 87), the pin 355 slides with its end 360 in the slot 361 of the bend 362 of the aligning tooth 359, causing it to move around the axis in the direction of arrow η (Fig. 14) 365 is pivoted. Here, the aligning tooth 359 is pressed onto the stop piece 43 by means of the spring 371 and is thus prevented from shifting downwards takes place when adding up to subtraction, i.e. when a positive value is brought out of the counter.

After the last digit of the counter Z 4 has been written blank, the SV key T, which has been automatically held down until then, is automatically released again, with all parts thus actuated return to their original position, so that no further arithmetic can take place . In the wagon step after the last computing process, the counter Z 4 migrating from the last computing point to the board point, all parts controlled by the counter Z 4 to prepare for the computing process are released, whereby they return to their starting position.

At the same time, the following mechanisms are operated in this last carriage step:

At the beginning of this carriage step, the counter Z 4 runs with the beveled tab 493 of the clear signal comb 494 (Fig. 20) on the pin 524 of the lever 525, whereby in a known way after pressing the clear sign key the clear star behind the value 417.95 is printed in column IV of the form (Fig. 29).

Furthermore, in this last carriage step, the part 521 with the bent nose 521 χ attached to the setting pointer of the machine acts on the roof-shaped bend 522 of the lever 514 in such a way that the latter is pivoted counter to the action of the spring 517 in a clockwise direction about its bearing screw 513 without thereby influencing other parts.

Likewise, in the aforementioned last carriage step, the stop 512 of the rail 440 (Fig. 19) is influenced by the Xase 511 of the lever 499 (Fig. 20) so that the rail 440 hinged at its right end to the coupling lever (not shown) for the carriage winding mechanism is depressed at its left end and pulled by its spring (not shown) in the direction of arrow q (Fig. 19). This closes the carriage elevator coupling and triggers the paper carriage to move to the right. is effected by the engine via a known transmission. As a result, the paper carriage is moved back to its extreme right position, with the platen F at the same time coming into the writing position with the next writing line s2 (Fig. 29j).

This mechanism is of course only operated when the lever 499 with the The nose 511 is brought in the effective position to the stop 512 of the rail 440 (Fig. 19), what by means of the knob 510 (Fig. 2 * 0) by hand by pivoting the lever takes place in the counterclockwise direction around the bearing screw 491. Thereby no the pin 507 against the action of the spring 506 pushed out of the detent recess 508 of the side part 460 to at the end the pivoting movement to snap into the detent lowering and thereby hold the lever in the pivoted position.

When the rail 440 is moved in the direction of arrow q (Fig. 19), the lever 434 is influenced by means of the pin-slot connection 437, 438, whereby it is pivoted about its bearing screw 435 in an iso-clockwise direction. This is where the lever works

74605a

434 with the end of his arm 441 on the pin 442 of the lever 253 and moves it against its spring 267 in the direction of arrow r, so that the articulated lever 246 S is pivoted counterclockwise around the bearing pin 245 and with the nose 248 outside Actual action to the assigned control plates 250 of the counters Z 1 to Z 4 comes.
Furthermore, the lever 434 acts on the rod 446 when pivoting with the shoulder rivet 448 and also moves it in the direction of arrow r. This movement is transferred to the articulated lever 443, where * 5 this is pivoted counterclockwise around the bearing pin 245 against a spring (not shown) and so with its nose 443 χ out of action on the control plates 4433 '"and 443 ζ of the counters assigned to it Z 1 and Z 2 come.

Through this mechanism, when the paper carriage runs backwards, when the control plates 250 (Fig. 19) of the counters Zi to Z4 hit the nose 248 of the lever 246 and the control plates 4433 »and 4432 of the counters Z ι and Z 2 on the nose 443 χ of the lever 443 resulting shocks avoided.

Of course, this mechanism is also activated when the car lift button, not shown, is pressed operated by hand.

After the carriage return movement has ended, the carriage lift button automatically returns to the starting position in a known manner, as a result of which the slide 440 also returns to the starting position counter to the direction of the arrow q . This return movement is also followed by the lever 434 and with it the parts 253, 246, 446 and 443, namely under the influence of the spring 267 and the above-mentioned spring (not shown).

In order to make the postings of line ζ 2 of form F (Fig. 29), first any one, for example the hundred key of the decimal tabulator, is pressed. When the carriage moves to the left as a result, the carriage returns to the position shown in Fig. 21, in which the counters Zi to Z 4 are again in position with the drive wheels 367, 532, 533 and 531, while form F with column I in Writing position. Here again the mechanisms described above are used to prepare for the calculation process.

Since no entry is to be made in column I, the paper trolley is moved further to the left by pressing the hundred key of the decimal tabulator corresponding to the value 153.42 in column II, whereby it again assumes the position shown in Fig. 26, in which the counters Z 2 ■ to Z 4 are in the real position to the drive wheels 3 ^ 7) S3 ² and 533 and the form F is with column II in the writing position.

With this left-hand movement, the parts controlled by the counter Z 1 are used for preparation the computing process is released again, after which they return to their original position.

When the counter Z 2 runs in here, the parts described above are again influenced in preparation for the computing process.

As a result, the control plate 274 acts on the lever 372 g (Fig. 13) and pivots clockwise, whereby the arithmetic unit switches to subtraction in the manner described above will. This is necessary because there is a credit item in column II, i.e. a Minus value should be entered.

Now the value 153.42 is transferred to the counter Z2, which is a minus work, by hitting the arithmetic keys R corresponding to this value and at the same time written down in column II of form F (Fig. 29), whereby the above or im The mechanisms described in the main patent are operated. This value is displayed in the display window F 3 of the counter Z 2. At the same time, the value 153.42 is also transferred in a subtractive sense by the drive wheel 533 (Fig. 26) to the complement counter Z 4, where it is displayed on the complement number rolls in the display window F 4 (Fig. 21). For this purpose, the lever 471a of the complement counter Z4 (Fig. 20 and 25) is pressed down by hand before entering the value 153.42. The segment lever 465 is pivoted with the lever 470 counter to the action of the spring 475 in the counterclockwise direction about the bearing screw 466. Here * ° 5, the lever 470 acts with the pin 473 on the end 520 of the lever 514 and pivots it counter to the action of the spring 517 clockwise around the bearing screw 513. At the end of the pivoting movement of the lever 470, the end 520 of the lever 514 slides from the pin 473, wherein the lever 514, following the tensioned spring 517, returns to the starting position and lies with its end 520 in front of the pin of the lever 470. As a result, the parts 471 α, 465 and 470 are held in the pivoted-out position. The pivoting movement of the segment lever 465 is also transmitted by the toothed segment 467 to the toothed segment 468 ¹ ^ o, whereby the latter is connected in a clockwise direction with the bearing pin 469

i8

. is panning. A cam (not shown), which is firmly connected to the toothed segment 468 and located on the inside of the side part 460, is pivoted in the same sense with -S, engaging the main drive wheel of the lowest point of the counter Z4 and thereby transferring the volatile one to the complementary numerals. Further, the pivotal movement of the Segmenthebeis (21 and 20 Fig.) Is transferred by the Zahnverbindung464,463 on the switching flap 456 465, which in the direction of arrow ".? (Fig. 20 and 25) is moved downwardly. As a result, the display window F is 2, through which the number wheels can be seen, covered and the display window F 4, through which the complement number wheels can be seen, exposed This pivots counter to the spring 487 clockwise around the bearing axis 483 into the position shown in Fig. 25 in dash-dotted lines.

The next value 264.53 to be carried forward in column III as the old balance is a! Minus item and should be identified as such in column III by being written in oblique numbers, which is achieved in the following way: First, the the value posted 264.53 corresponding hundreds key of Dezimaltabulators, whereby the paper carriage travels so far to the left that the counters Z1 to Z4 again taking in Figure 2j. position illustrated in which the counters Z3 and Z4 in operative position to the drive wheels 367 and ~, 2> ² , while form F with column III is in the writing position. During this left-hand movement of the car, the parts controlled by the counter Z 2 for the purpose of preparing the arithmetic process are released again, whereby they return to the starting position.

When the counter Z 3 starts running, the parts described above are actuated in preparation for the arithmetic process. Since a negative value is to be booked after the previous one, the arithmetic unit must be switched to subtraction, which is achieved by pressing the general reverse key Γ 2 (Fig. 12 ') as follows:

Upon depression of the reverse button General Ta (Fig. 10 and 12), the levers 329 and 330 against the action of a spring 329 in the opposite χ L ^T hrzeigersinne to the bearing 331 pivots.

Does it lift into slot 372? " (Fig. 13) the rod 372 c protruding pin 329 a to the rod 372 c (Fig. 13) and pivoted it counterclockwise around the rivet 372 rf, where it slides with the slope 372.1 "along the pin 372g and is thereby shifted in the direction of arrow i . Here, the levers 372 and 373 are pivoted with the axis 332 in the counterclockwise direction and the arithmetic unit is switched to subtraction in the manner described above to have the device. Likewise, the lever 329 during pivoting to the parts 326, 323, 318, 315. 319. 3 °. 5 -97 · 3 ° 7 moved without having ⁷ S further influence on the device.

As described above, the parts 376, 385, 388, 394, 398 and 405 have now been actuated by the control plate 377 / (Fig. 18 and 24), with the lever 405 turning counterclockwise around the rivet 409 (Fig. 17) was pivoted. Accordingly, when the key lever 330 of the general reverse key T 2 is actuated, it presses the nose 410 that has come into its area (Fig. 17 and ιSj of the lever 405. so that the latter is moved downwards in the direction of the arrow m The value 264.53 is now written down in column III of form F (Fig. 3) by pressing the corresponding arithmetic keys R (Fig. 3), whereby the operations already described Repeat this value, since the platen was switched over after the previous one, is printed in oblique numbers.

The value 264.53 is not displayed in the counter Z3, which is an empty unit, but only transferred to the complementary counter by the drive wheel 532 (Fig. 27), subtractively according to the setting of the arithmetic unit. Accordingly, the value 264.53 is added ^to the likewise negative value 153.42 already contained in the counter Z4, so that the value 417.95 is now displayed in the display window F 4 of the counter Z4.

This value is then brought out through Summenzug from register Z4 while 5 if in an oblique numbers \ vas is achieved in the column IV of the form / * 'written, namely likewise ⁿ as follows (Fig. 29):

For this purpose, the hundred tab key of the decimal tab corresponding to the value 417.95 is pressed again, whereby the paper trolley receives another movement to the left and the counting

works Z ι to Z 4 in the position shown in Fig. 28, in which the counter. Z 4 is in the effective position for the drive wheel 367 and the form F with column IV is in the writing position.

During this left-hand movement of the car, the Z3 counter is used for preparation of the calculation process actuated mechanisms are released again, whereby they are in their starting position to return.

When the counter Z4 runs in here, the above-described Mechanisms for preparing the calculation process influenced.

The control plate 377s, which was pivoted as described above, no longer actuates the roller lever 372 q for reversing the arithmetic unit to subtraction, but it now affects the lever 376 (Figs. 25 and 18). The lever 372 g for reversing the arithmetic unit to subtraction is therefore not actuated here, namely not because a negative value is to be brought out of the counter Z4, which, as is well known, is achieved by adding up.

According to the above, the lever 376 (Fig. 18) is driven by the control plate 377.? (Fig. 25 'and 18) actuated. Here parts 376, 385, 388, 394, 398 and 405 become in the manner previously described actuated. The lever 405 is not only active with its nose to the general reversing key lever 330, but he also stands with his nose 411 in action to the bent one Lug 412 of slide 414 (Fig. 18). ·

Furthermore, it should be recalled that the lever 372 q (Fig. 13) appears to be pivoted counterclockwise via the parts 372 n, 372h, 37Zf ₁ 372c, 372, 332, 336, 340, "339, 347 and 348 the lever 350 together with the pin 355 in the opposite direction of the

+5 arrow i has been moved so that its end 360 (Fig. 14) comes out of action with the slot 361 of the aligning tooth 359, while the end 356 of the pin 355 comes into action with the slot 357 of the aligning tooth 359.

If the ^ "F key T (Fig. 1 and 2) is now depressed, the value 417.95 is automatically brought out of the counter Z4 in places and in column IV of form F (Fig. 29) in the manner described above. written down.

During the downward movement of the slide 414 in the direction of arrow m (Fig. 18), the latter presses on the nose 411 of the lever 405, whereby the latter is also moved downward in the direction of arrow m and thereby causes the platen change-over in the manner described above, so that the Value 417.95 is also printed in oblique numbers in column IV of form F.

When the lever 350 is pivoted with the axis 87 (Fig. 13), the pin 355 slides with the end 356 in the slot 357 (Fig. 15) of the bend 358 of the alignment tooth 359. This causes the alignment tooth 359 to move in the direction of arrow t (Fig . 15) is pivoted about the axis 365, whereby it is also, as described above, pressed against the stop 432 (Fig. 14) by the spring 371. The alignment tooth 359 is thus pivoted in the opposite direction, as described above. This is necessary because here a negative ■ value is written out of the totalizer by means of a summation.

After the counter Z4 has been written empty, the ^ 'key lever T is automatically released in the manner described above.

The same mechanisms are also created by the last carriage step that takes place here operated as previously described.

When the lever 514 is pivoted clockwise about the screw 513, the end 520 releases the pin 473 so that the lever 470 and all parts connected to it return to the starting position under the action of the spring 475. This return movement is also followed by the control plate 377 s of the tensioned spring 487.

The nose 497 of the bend 457 of the switching flap 456 gives the clear signal comb only free when the number rollers of the positive number roller set of the counter Z4 are already at zero, so that only then does the clear-character comb with the noses 4944- go into the can come up with assigned grooves.

If, for example, the values stored in the counter Z1 are to be added by adding them are written out of the counter, this is achieved as follows:

First, the counter Zi, as described above, is in the arithmetic position brought.

The levers 281 and 376 are not actuated here, since the counter Zi does not have the control plates 377 / and 282 χ.

By pressing the 5 "F key T (Fig. Ι and 2) the value stored in the counter Z1 is automatically brought out of the counter Z1 in places and written down in column I of the" Form F (Fig. 29), the previous mechanisms described are operated. When moving the

2Ö

Shifter 414 i ⁿ the direction of arrow "ι (Fig. 12), the carrier 307 moved in the same sense. As a result, the general reverse key T 2 is pulled down via the parts 297, 305> 319, 316, 318, 323, 326 and 329, 330, whereby the arithmetic unit is switched to subtraction in the manner described above.
