general description

The device according to the invention takes place e.g. B. in one in addition to the usual types of invoices (Addition, subtraction) typewriter equipped for multiplication (Fig. 1) with automatic total pull according to patent 727 648 application. The brevity For the sake of this, known functions of the machine will only be described to the extent that they facilitate understanding of the invention.

It is assumed that in accounting work with the machine, two factor values, e.g. B. 24.00 X o, i2, are to be multiplied. For this purpose, the preparation key 1 (Fig. 1) is hit and the typewriter is preset for multiplication work. After the paper trolley 2 and the vertical counters 3, 3 1, 3 _{6 moved with it have moved} into the respectively required working position by pressing the usual arithmetic keys 4, the multiplicand 24.00 is keyed in for the time being. This multiplicand value is set via an infeed wheel E (Fig. 20), which is adjustable in the horizontal direction depending on the movement of the paper carriage 2, and via the corresponding wheels of a multifunctional gear train F in the meshing racks A, D of a rack system 132 of the multiplier device . At the same time, the value 24.00 is entered in the corresponding vertical counter 3 and printed on the form clamped in the paper trolley 2 using the writing device 7 (Fig. 2).

Then after further tabulation of the paper cart 2 and the compulsory setting of the feeder wheel E (Fig. 20) opposite the selected decimal place of a multiplier wheel train C, the multiplier 0.12 is keyed in by pressing the usual arithmetic keys 4. This value is set via the racks C, D of the rack system 132 in the wheels Z and H (FIG. 21) of a multiplier mechanism 64. At the same time, the multiplier value is entered into the relevant. Vertical counter 3 ,, introduced and printed on the form clamped in the paper carriage 2 by means of the writing device 7 (Fig. 2) of the machine.

In order to initiate the multiplication process, after the paper carriage 2 and the vertical counter 3 ", in which the pro no product is to be saved, have been tabulated in the working position, the result key 8 (Fig. 1) depressed. Depending on this, the following setup of the Multiplier actuated:

Drive and control device for the stepping device

A button lever 9 carrying the result button 8 (Figs. 2 to 4) is by means of its bearing hub 10 on one hand in the machine

frame 5 and on the other hand in the multiplier receiving frame ii attached axis 12 pivotally mounted. A tension spring 14 is attached to a hook-like arm 13 (Fig. 3 to 5) of the key lever 9, which permanently influences the key lever 9 in a counterclockwise direction about the axis 12 , the key lever 9 striking a stopper 15 in the rest position. A locking pawl 17, which is pivotably arranged on the key lever 9 by means of a shoulder screw 16, locks the key lever 9 in the depressed position in that a lug 18 of the locking pawl 17 jumps into a locking groove 19 'of a locking bar 20. The required pivoting movement of the pawl 17 is provided by a tension spring 21.

An upwardly extending arm 22 of the key lever 9 is by means of a screw 23 with

2o 'connected to a control slide 24. This is displaceable in the direction of arrow 25 and acts due to its right-hand bend 26 (Fig. 3 and 4) together with an upwardly angled nose 27 of a control angle 28 (Fig. 7 and S).

The latter itself is by means of a screw 29 on an angled tab of a Bearing block 30 (Fig. 4 to 6) mounted pivotably, which by means of screws 31 (Fig. 3 and 4) is screwed to the frame 11. In the one protruding forward A pin 32 is attached to the arm of the control bracket 28 (Figs. 7 and 8). This protrudes into a Ring groove 33 of a coupling sleeve 34 (Fig. 3

till 8). On the latter, two claws 35 are provided on the left front side and two claws 36 are provided on the right front side. At the given point in time, the claws 35 can engage in corresponding jaws 37 of a roller lever 38 (FIG. 4), while the claws 36 normally engage in jaws 39 of a roller lever 40. The coupling sleeve 34 is now seated displaceably in the horizontal direction, but non-rotatably, on a shaft 4i on which the roller levers 38 and 40 are also mounted in an immovable, but pivotable manner. The Welle41 (Fig. 3 and 4) is rotatably mounted in two bearing boss screwed to d ^em frame 11 bearing members 42, 43 and is secured by a screw 44 against horizontal displacement. The rotational position of the shaft 41 is secured by a detent lever 45 (Figs. 4 to 6) which is fixedly arranged on it. An arc-like front edge 46 of the notch lever 45 and two notches 47 and 48 provided there cooperate with a roller 49 of a safety lever 50. The latter is arranged pivotably on the axis 12 between two sleeves 51 and is permanently influenced in the reverse direction of rotation of the clockwise about the axis 12 by a tension spring 52 acting on its downwardly projecting arm. Accordingly di £ roller 49 of the safety lever 50 constantly in contact with the front edge 46 of the Rastenhebeis 45 or with its notches 47 or ^48: held, whereby if one of the securing: stanchions 47, 49 or 48, is made 49, the ι Parts 45, 41, 34 are secured in the set position.

The roller lever "38 is bent to the right (Fig. 4) so that its rotatable on it mounted roller 53 protrudes into the path of a cam disk 54. One on the roller lever 38 acting tension spring 55 moves it always in the opposite direction of rotation of the clockwise around the shaft 41, the roller 53 of the roller lever 38 in contact with the circumference the cam 54 is held. The cam 54 sits loosely rotatable on the usual driven by the engine of the machine continuously in the direction of rotation of arrow 56 partially square main drive shaft 57. On the cam disk 54 is by means of rivet slot connections a coupling pawl 58 slidably disposed. This coupling pawl 58 can with its tooth 59 in a fixed engage the clutch wheel 60 seated on the main drive shaft 57. In the rest position of the Key lever 9 of the result key 8, however, is protruding from its rearward Arm 6i disengages the coupling pawl 58 against the action of a compression spring 62 with the clutch's wheel 60 moved so that the Drive coupling 54, 58 is stationary.

Actuation rings of the drive and control device for the Stepping device

If you now press the result key 8 (Fig. 5) to calculate the product, so the key lever 9 pivots counter to the action of the spring 14 in a clockwise direction about the axis 12, in which pivoting the pawl 17 also takes part. In the lower position of the key lever 9 snaps under the influence of the spring 21 the pawl 17 by means of its locking tooth 18 in the locking groove 19 of the locking bar 20 a, whereby the button lever 9 is locked in the depressed position according to Fig. 6 will.

Depending on the clockwise pivoting movement of the button lever 9, the control slide 24 is moved in the direction of the arrow 25 via the drive connection 22, 23 (FIG. 4). Its bend 26 acts on the nose 27 of the steady bracket 28 and pivots the latter in a clockwise direction (Fig. 8) about its bearing screw 29.

Groove 33 of the coupling sleeve 34 engaging pin 32 of the control bracket 28 moves thereby the coupling sleeve 34 on the shaft 41 to the left; consequently the claws kick 30 of the coupling sleeve 34 out of the recesses 39 of the roller lever 40, and the claws 35 of the coupling sleeve 34 then come with the recesses 37 of the roller lever 38 engaged.

When pivoting the button lever 9 clockwise from the rest position according to the Fig. 4 and 5 in the position according to Fig. 6 also gives the Ann 61 of the key lever the coupling pawl 58 free. This is now shifted by the compression spring 62 to the clutch wheel 60, the tooth 59 of the Coupling pawl 58 comes into engagement with the coupling wheel 60 of the main drive shaft 57. Now take the clutch pawl 58 and the cam 54 to rotate the Main drive shaft 57 in the direction of rotation of arrow 56 part.

Depending on the or the revolutions of the cam 54 are now the ones needed to multiply the keyed-in factors 24.00 and 0.12 ! Machine operations initiated or driven. These operations and the - these effecting devices of the multiplier are not of interest here and are therefore not explained in more detail. The product formation itself takes place in the next to the multiplier plant 64 Product plant 65 (Figs. 9 and 20) instead by adding the multiplicand to 24.00 depending on the Nominal value of the multiplier 0.12 initially once and after stepping the Gear trains 64, 65 added two more times to the left in gear train 65 (product group) will. The number of additions of the multiplicand 24.00 in the product plant becomes 65 accordingly controlled according to the nominal value of the multiplier 0.12. The latter itself became automatic when it was keyed in, as has already been pointed out above in the two lowest arithmetic digits (tenths of a digit Z and hundredths of a digit?) of the gear train 64 (multiplier unit) is set. The multiplier 64 is set, as shown in Fig. 9, in the present embodiment composed of seven wheels (arithmetic units). There are therefore the five left wheels of the multiplier unit 64, d. H. the wheels of the single computing point and the computing points of higher ones. Order to zero. the Understandably, computing points of the multiplier unit 64 which are set to zero control no addition of the multiplicand 24 in the product plant 65, but the relevant ones Computing points of the multiplier 64 only have the task of a left switching step of the gear trains 64, 65 to initiate. These so-called idle circuits are necessary because each Multiplication task of all computation points of the multiplier unit 64, started from the highest, d. H. computing point located furthest to the left to the lowest Computing station, are processed one after the other. As a result, there will be a number for the time being Empty circuits take place before the addition of the multiplicand in the product plant 65 begins. These and the step circuits of the multiplier mechanism 64 and that also result when the factors 24.00 χ o, i2 are multiplied of the product plant 65 are switched by ■ a facility whose structure should be described below.

Arrangement of the stepping device

On the frame 11 (Fig. 2, 3, 9, 10, 12) a support 67 is screwed by means of screws 66. Two prism rails 70 and 71 (Fig. 12) are fastened to this in turn by means of screws 68, 69. Balls J2 roll in the prisms of the rails 70, 71 and also roll in prisms of a slide 73. In this way, the slide 73 is displaceable along the carrier 67 in the horizontal direction. A U-shaped bearing part 75 is screwed tightly to the slide 73 by means of screws 74. An axle 76 is fixedly arranged in the two legs of the bearing part 75. On the latter are connected by hubs ¹ J ^ and 78 (Fig. 10), the two legs of a (j-shaped contact bridge 79 mounted. The forwardly projecting connecting web 80 of the switching bridge 79 is also U-shaped. This portion 80 engages a roller 81 (Figs. 2 to 4 and 12) and a roller 82. The roller 81 is on a bearing rivet 83 of a control lever

84 rotatably mounted, while the roller 82 is in the same way on a control lever

85 is stored. Both control levers 84 and 85 are firmly pinned to the shaft 41. ^ As a result of these control connections So, 81 and 80, S2 , the position of the switching bridge 79 is determined as a function of the position of the Welk 41.

Iu the two legs of the switching bridge (Figs. 2, 9, 10 and 12) is an axis 86; _; attached. On this axis 86 are two levers 87 and SS within the switching bridge 79 pivotally arranged. The lever 87 is by means of a in the left leg of the Bearing part 75 attached guide pin 89, which protrudes in a slot 90 of the lever 87, guided in the vertical direction. A similar The lever S8 is guided by

in its longitudinal slot 91 a guide pin 92 fastened in the right leg of the bearing part 75 protrudes. The two levers 87 and 88 are rigidly connected to one another by means of an axle 93 fixed in their downwardly projecting parts to form a U-shaped whole. On the axle 93 (Fig. 9) the seven wheels of the multiplier wheel train 64 and next to them the wheels of the product wheel train 65 are rotatably mounted independently of one another and are kept at the required distance from one another by means of their bearing hubs. In the width area of the right-hand bearing hub of each individual wheel 64, a tooth 94 (Figs. 9 and 11) corresponding to zero is widened to the right. In the movement path of the zero tooth 94 of each wheel 64 protrudes both a notch-like nose 95 and an arm 96 of a switching lever 97, 20, which is pivotably mounted on the axis 86. Since such a shift lever 97 is assigned to each of the seven wheels 64, seven shift levers 97 are pivotably mounted next to one another on the axis 86, independently of one another. The required distance is obtained from the bearing hubs 98 of the shift levers 97. One end of a tension spring 99 acts on each switching lever 97 (FIGS. 10 to 12) below the bearing point 86. The other ends of these tension springs 99 are suspended in bores in a bar 100 (Fig. 12) which is screwed onto the bearing part 75. Each tension spring 99 influences its switch lever 97 in a clockwise direction around the axis 86, and, provided that the wheels 64 are in the neutral position, the lugs 95 of the switch lever 97 each abut the opposite zero tooth 94 of the wheels 64 (Figs. 10 to 12). In the zero position of the __ "., Shift lever gj an upwardly protruding nose ιοί provided on each shift lever 97 protrudes into the path of a nose 102 of a pawl 103, each shift lever 97 being able to interact with the pawl 103 independently of the other at the given moment.

The pawl 103 is by means of its bearing hub 104 (Fig. 11) on a self-tapping screw 105 (Fig. 9, 10 and 12) pivotably mounted. To the right of this pawl 103 is means a bearing hub 106 (Fig. 11) as well a second pawl 107 is pivotably mounted on the shoulder screw 105. The shoulder screw 105 is screwed into a U-shaped carrier 108, which is again screwed onto the upper prism rail 71 by means of screws 109. A torsion spring 110 (FIG. 10) is wound around the bearing hub 104 of the pawl 103. This influences the pawl 103 continuously in the counterclockwise direction of rotation around the bearing screw 105, this pivoting movement being limited by that a nose 113 of the pawl 103 on a flap 114 angled to the right (Figs. 10 and 12) of the carrier 108 strikes.

_{A torsion spring iro a} (Fig. 11) is also wound around the bearing hub 106 of the pawl 107. This influences the pawl 107 continuously in a counterclockwise direction around the bearing screw 105 until its lower edge rests on a tab 112 (FIG. 11) of the pawl 103 that is angled to the right.

In this rest position of the two pawls 103 and 107, the latter rests by means of its nose 115, as shown in Fig. 10, on the left flank of the left tooth n6 _a (Fig. 10) of a row of teeth 116, while the pawl _{103 is located below, ie outside of the path of movement of the tooth Ii6 a} , by means of its nose 117, which is offset to the left by a section of a switching step. In this way, a sliding movement of the carriage 73, 75, 64, 65 in the direction of movement of the arrow 119 is inhibited by the pawl 107 under the tension of a spring 1.18 (Fig. 9, 10). In the switching step, ie at a distance between the wheels 64 and 65, further teeth 116 are arranged on the bearing part 75.

In the switching step distance, the highest arithmetic point of the is to the left of the switching lever 97 Multiplier mechanism 64 a gear lever 120 (Fig. 9, 10, 15 to 17) on axis 86 pivoted.

This shift lever 120 (Fig. 17) engages above its mounting 86 a tension spring 121, which the shift lever 120 permanently in counterclockwise about the axis 86 influenced. In the rest position of the Shift lever 120 his downwardly extending arm 122 on the circumference of one between the The wheel 64 corresponding to the highest computation point and the lever 87 are arranged on the axle 86 Intermediate ring 123. Because of this, it is usually a protruding one Nose 124 of the shift lever 120 outside the area of the nose 102 (Fig. 15) of the pawl 103. Another downwardly protruding arm 125 of the shift lever 120 is widened to the right Nose 126 is provided. This is followed by a nose 127, which is also widened to the right (Fig. 15 to 17) one around screw 105 pivoting control lever 128 controlled. The control lever 128 is also able to use another nose 129 over a tooth 130 the switching bridge 79 to control. Furthermore, the nose 127 of the control lever 128 one after the other with lugs 131 (Figs. 10 and 16) arranged on the switching levers 97 works.

Mode of operation of the stepping device. Blank steps

For the time being, it should be remembered again briefly that when the multiplicand 24.00 is introduced, this value is added to the racks A and B corresponding to the units or tens position of a set of racks 132 located below the gear train 65 and which can be moved forward (Fig. 9 and 20) has been discontinued. It should be mentioned that both in the multiplicand ais and in the multiplier works, zeros before or after the comma for the purpose of calculating the JSs of the product only determine the necessary decimal places of the calculating works, but have no influence on the numerical product formation. As a result, these computing locations containing zeros are treated in the following description only to the extent that this appears necessary for an understanding of the invention.

When the multiplier 0.12 was keyed in, it was set via the toothed racks D, C opposite the tenths Z and hundredths H of the gear train 64 in the aforementioned gears Z and Ii .

"To the left of the rack system 132 a rack 133 is provided, which during the multiplication process during one revolution of the main drive shaft 57 (Fig. 18) the gear of the multiplier mechanism 64 which is brought into engagement with it moves back by one unit. These functions are known per se, so they will not be discussed in more detail here shall be.

The wheel of the multiplier wheel train 64, which corresponds to the highest arithmetic point and is therefore located furthest to the left, is normally, as can be seen from FIG to be able to produce the aforementioned wheel of the gear train, to initiate a left-hand switching step of the slide 73,75,64,65. This task is assigned to the shift lever 120 (Figs. 9, 15 to 17), in the plane of which the pawl 103 is in the normal position of the slide γτ ,, 75, 64, 65.

If the result key 8 j (Fig. I) is pressed to calculate the product 0.12 χ 24.00 = 2.8800, it becomes known! the coupling sleeve 34 is moved from the rest position in accordance with FIG. 7 to the left into the position in accordance with FIG. The pin b fastened in a control slide α (Fig. 3) also protrudes into the annular groove 33 of this coupling sleeve 34, so that a left shift

' Exercise of the coupling sleeve 34 also participates in the control slide α , against its spring c. As a result, there is the increased control stage d (Fig. 17) of the control slide o, which so far has the control lever 128 against the action of its spring i28 _a in his

ι Non-effective action (Fig. 15 and 17) held, free, so that the control lever 128 is now under the

j The action of its tension spring I28 _a swivels clockwise around the screw 105 (Fig. 16), whereby its front arm e comes to rest on the lower step / the control slide α.

The nose 127 of the control lever 128 acts while doing this on the nose 126 of the shift lever 120 and swivels it counter to the action of the spring 121 in a clockwise direction the axis 86. Accordingly, the nose 124 of the shift lever 120 is in the area of the nose 102 of the pawl 103 moves. When enforcing of the control lever 128 simultaneously engages its nose 129 under the nose 130 of the switching bridge 79.

Depending on the depression of the result key 8 is also known to be Coupling 58, 59, 60 (Fig. 4 and 6) closed, so that due to the latter, the cam 54 participates in the revolutions of the main drive shaft 57 in the direction of rotation of the arrow 56.

At the beginning of the rotation of the cam

54 gives the raised cam part 54 ,, (Fig. 4) of the cam disk 54, the roller 53 of the roller lever 38 free. As a result, the pen tries

55 the roller lever 38 and across the coupling 34 * 35 * 37 the. To pivot shaft 41 in the direction of rotation of arrow 134. According to this endeavor of the spring 55, the switching bridge 79 (Fig. 12) would also be pivoted clockwise around the axis j6 via the control connections 84, 81, 80 (Fig.:>) And 85, 82, 80. However, since the nose 129 (Fig. 16) of the control lever 128 engages under the nose 130 of the switching bridge 79, the pivoting movement of the latter is prevented. As a result, the parts 85, 84, 34, 38 (FIG. 4) cannot be pivoted either, so that the roller 53 of the roller lever 38 floats freely with respect to the lower curve section 54 ″ of the cam disk 54.

The switching bridge 79 and the parts 86, 87, 93, 64, 65 and 88 (Fig. 2 and 10) remain consequently in the rest position according to Fig. 12, ft'o due to the disengaged position of the gear trains 64 and 65 of the racks 132 is retained.

Depending on the further rotation of the cam 54 in the direction of rotation of the

Arrow 56, the racks 132 set according to the factor values, in the present case the racks A and B (FIG. 20), are now reset to zero in a known manner. Due to the open drive 64, 132 and 65 (Fig. 9), no addition of the factor values 0.12 and 24.00 in the corresponding gear trains 64, 65 can take place. The two racks A and B are then automatically reset according to the multiplicand value 24.00, depending on the intermediate gear Zw (Fig. 20), in which the multiplicand value 24.00 was turned when the racks A and B were reset to zero . These intermediate gears Ζτυ are now set to zero again and transfer their recorded value 24.00 back to the racks A, B of the rack system 132. These operations are known and will not be described in more detail here. In contrast, the racks 132 opposite the multiplier gear train 64 remain in their zero position.

When the cam disk 54 (Fig. 4) is rotated, it now acts with its rising Curve section 54 ,, on the roller 53 (Fig. 6) of the roller lever 38 and swivels these and via the coupling 37, 35, 34 the shaft 41 counter to the action of the spring 55 in the opposite direction of rotation of arrow 134. Via detent lever 45 that swivels with it the locking device 47, 49 is opened,

and 'the roller 49 of the safety lever 5 then rolls onto the arcuate leading edge 46 of the detent lever 45.

During the pivoting movement of the shaft 41 in the opposite direction of rotation of the arrow 134 also via the drive controls 84, 81, 80 and 85, 82, 80 the switching bridge 79 'in the opposite one Pivoted clockwise direction of rotation about axis 76 (Fig. 14). At this The parts 86 also take a pivoting motion,

+5 87, 93, 64, 65, 88, 120 (Fig. 15), 97 part, making parts 87, 93, 64, 65, 88 as a result of the pin slot guides 90, 89 (Fig. 10) and 91, 92 are raised vertically. The shift lever 120, which is in the position shown in Fig.

16, acts as it goes up by means of the nose 124 (Fig. 16) from below on the nose 102 of the pawl 103 and influences it counter to the influence of the torsion spring 110 (Fig. 10) in a clockwise direction around the bearing screw 105 Switching tooth 117 of the switching pawl 103 in the movement path of _{the left tooth i i6 a} (Fig. 10) of the bearing part 75. "

At the same time the pawl 103 acts by means of its bend 112 (Fig. 11) from the bottom of the edge in the pawl 107 and pivots the latter also in a clockwise direction against the action of the torsion spring ι io _a around the shoulder screw 105. Here, the tooth 115 of the The pawl 107 is moved outside the area of the tooth ii6 _{a of} the bearing part 75. As a result, the slide 73>75> 64, 65 is released and now moves under the influence of the tension spring 118 in the direction of arrow 119 to the left as far as the stop on the tooth 117 of the raised pawl 103. This movement corresponds to part of a switching step.

Meanwhile, the roller 53 (Fig. 6) · of the roller lever 38 has reached the raised _{cam part 54 ώ of} the cam disk 54. With the further rotation of the cam disk 54 in the direction of rotation of the arrow 56, the roller 53 now rolls on the sloping cam part 54 ^ (Fig. 4), whereby the roller lever 38 and via the coupling 37, 35, 34 the shaft 41 under the course of the Spring 55 is pivoted in the direction of rotation of arrow 134 from the position shown in Fig. 6 into the rest position shown in Fig. 4. In this position, the locking device 47, 49 is restored under the action of the spring 52. At the same time, via the control connections 84, 81, 80 and 85, 82, 80 (Fig. 2), the switching bridge 79 is pivoted clockwise around the axis 76 from the position shown in Fig. 14 to the rest position shown in Fig. 12, whereby the parts 87, 93, 64, 65, 88, 86, 97, 120 are moved vertically downwards again. Accordingly, the nose 124 (Fig. 16 and 17) of the switching ^9S hebeis 120 releases the nose 102 of the pawl 103 again, which now under the action of its torsion spring 110 in the counterclockwise direction around the screw 105 into the rest position according to Fig. 10 and 12 pivots back, its stop lug 113 striking the angled tab 114d of the U-shaped support 108. In this case, by means of its turn the pawl 103 is 112 (11 Fig.), The lower edge 111 of the pawl 107 freely, so that the latter 11 o _a likewise mitschwenkt under ^los the influence of the torsion spring in the opposite a clockwise direction around the screw 105 and thereby by means of its tooth 115 The gap between the two teeth n6 _a and ii6 ₆ (Fig. 10) of the bearing part 75, which is located furthest to the left, falls into place. In addition, the pawl 103 releases the leftmost tooth n6 _{a of} the bearing part 75 by means of its tooth 117. Here- ¹¹ S by the carriage 73, 75, 64, 65 free for further leftward movement so that now under the course of the spring 118 of the carriage 73, 75, 64, is moved to the other path of a switching step in the direction of arrow 119 65 until the second tooth n6 ^ from the left of the tooth 115 of the pawl 107

is held. It is accordingly the carriage 73, 75, 64, 65 one switching step behind has been switched to the left, so that now the left wheel (Fig. 9) of the multiplier gear train 64 is opposite the rack 133 and the shift lever 97 located furthest to the left (Fig. 10) lies in the plane of the pawl 103.

At the same time, the nose 126 slides (Fig. 17) of the shift lever 120 from the nose 127 of the control lever 128 sideways, whereupon below the influence of the spring 121 of the shift lever 120 in the reverse clockwise direction to the Axis 86 swivels from the position shown in Fig. 16 into the rest position shown in Fig. 15. As a result of the slide switching step, the switching bridge 79 also comes out with its nose 130 Area of the nose 129 of the control lever 128.

In the meantime, the cam disk 54 (FIG. 4) has completed a full turn and the second turn in the direction of rotation of the I 'file 56 begins. After a short rotational path of the cam disk 54, its raised cam part 54 ″ releases the roller 53 of the roller lever 38, and the spring 55 tries again to move the parts 38, 37, 35, 34, 41, 45, 84 and 85 in the direction of rotation of the arrow 134 and the switching bridge 79 to move clockwise beyond the rest position, ie to bring the gears 64, 3 "65 (Fig. 9) into engagement with the racks 132 and 133, respectively. However, since the highest computing point of the multiplier gear train 64 is at zero and consequently the switching lever 97 controlled by the zero tooth 94 of the wheel corresponding to this arithmetic station assumes the position according to Fig. 12, this switching lever 97 is supported with its nose 131 (shown in phantom in Fig. 16) on the nose 127 of the control lever 128 and prevents thereby inserting the wheels 64, 65 into the racks 132 and 133, the latter for the reason that, due to the setting of the highest computing point of the multiplier gear train to zero, no addition of the multip likanden may take place in the product gear train 65, but the arithmetic stations of the multiplier gear train 64, which are set to zero, are only intended to initiate an empty step circuit of the slide 73, 75, 64 and 65. The roller 53 of the roller lever 38 consequently floats freely as long as the lower cam section 54 ;, the cam disk 54 rotates past the roller 53. Only during the following Drehäbschnittes of the cam disk 54 are _t again due to the rising cam portion 54. Via the parts 53, 38, 3 /, 35-34.4L ⁸ 4> 85, Si, 82, 80 (Fig. 4) the switching bridge 79 (Fig. 10) and the parts 86, 87, 93, 64, 65 , 80, 97 brought from the rest position according to 6u Fig. 12 into the switching position according to Fig. 14. The switching lever 97 lifts the highest point of the multiplier gear train 64 by means of its nose 101, the switching pawl 103 and. Via the drive connection 112, 111 the pawl 107, so that the tooth 115 of the latter _{releases the second tooth n6 fi} from the left of the bearing part 75 and after the carriage 73, 75, 64, 65 under the influence of the tension spring 118 by a partial distance one switching step has jumped to the left, the tooth 117 of the pawl 103 intercepts this movement. During the further rotation of the cam disk 54 (FIG. 4) in the direction of rotation 56, the sloping curve segment of the cam disk 54 releases the roller 53 again. Accordingly, the switching bridge 79 and the parts 86, 87, 93, 64, 65, 80, 97, 120 moved again from the switching position according to Fig. 14 into the rest position according to Fig. 12. The influence of the nose 101 of the switching lever 97 of the highest computing point of the multiplier gear train 64 on the pawl 103 is canceled again, so that now the pawls 103 and 107 swivel back into the rest position under the effects of their torsion springs 110 and no ,, respectively. As a result, the pawl 103 releases the tooth 1 id _{b of} the bearing part 75 which it had previously stopped. The slide 73, 75, 64, 65 is then switched by the spring 118 by the remaining distance of one switching step to the left (arrow direction 119), the switching pawl 107 with its tooth 115 now the third tooth 116 ,. intercepts from the left. As a result of this switching step of the slide 73, 75, 64, 65, the wheel of the next lower computing point, second wheel from the left, adjacent to the highest computing point wheel of the multiplier unit 64 (Fig. 9) moved into the area of the rack 133 and the switching lever 97 assigned to this computing point moved into the plane of the pawl 103.

The cam disk 54 meanwhile continues to rotate in the direction of rotation of the arrow 56. During its third full rotation, the Slide 73, 75, 64, 65 initiated. According to the setting of the multiplier rudder 64 on 00000 12 repeat themselves probably this as well as when the next lower arithmetic digits of the multiplier gear train are set to zero 64 the above described operations. Because of this, the Carriages 73, 75, 64, 65 with each subsequent full revolution of the drive coupling 54, 58 step by step to the left past the rack 133 until the tenths of a second position Z of the multiplier gear train 64 comes to stand opposite the rack 133 (Fig. 21). In the course of these so-called empty

switching steps are additions of the multiplicand 24.00 in the product gear train 65 is prevented, as in the working position each set to zero arithmetic part of the multiplier gear train 64 the lock 131, 127 (Fig. 16) takes effect.

Product en education

After completion of the aforementioned switching steps of the slide 73, 75, 64, 65, the wheel of the tenths of a part Z of the gear train 64 is now opposite the rack 133 (Fig. 21). The tenth of the wheel Z was turned one unit clockwise when the multiplier 0.12 was introduced (Fig. 13). The zero tooth 94 of the tenth wheel Z has released the nose 95 of the opposite shift lever 97, so that the latter swings under the influence of its spring 99 in the clockwise direction of rotation around the axis 86 from the rest position according to Fig. 12 into the position according to Fig. 13. The switching nose 101 of the switching lever 97 pivots outside the region of the nose 102 of the switching pawl 103 and the nose 131 of the switching lever 97 pivots outside the region of the nose 127 of the control lever 128 (indicated by dash-dotted lines in FIG. 13). As a result, as soon as the cam 54 (Fig. 4) rotates in the direction of rotation of the arrow 56, the raised part 54 _{a of} the cam 54 releases the roller 53 of the roller lever 38, the roller lever 38 and the parts 37, 35, 34, 41, swing, 45, 84 and 85 under the influence of the tension spring 55 in the opposite direction of the arrow 134 from the DTV rest position as shown in figure 2 in the position which corresponds to illustrated in Figure 18 of the..; the roller 53 (Fig. 4) of the roller lever 38 rolls along the lower cam part 54 ^ of the cam disk 54. As a result, via the control connections 84, 81, 80 and 85, 82, 80, the swivel bridge 79 is swiveled clockwise (Fig. 18) about the axis 76 and the parts 86, 87, 93, 64, 65, 88, 120 and 97 moved downwards. As a result, the wheels 65 mesh with the racks 132 and the tenth wheel Z mesh with the rack 133 and the radius of the wheels 64 mesh with the left rack 132.

This engagement position is now established by the locking mechanism 48, 49, 50, 52 secured.

The further rotation of the cam 54 (Fig. 2 and 4) brings now due to displacement of the back corresponding to the multiplicand 24 set Zähnstangen · A, B (Fig. 20) to zero, an addition of the value of 24.00 in the example. Z. opposite wheels I, II (Fig. 21) of the product plant 65. Equal-60. At the same time, the rack 133 rotates the gear Z of the multiplier gear train 64 which is engaging in it at this moment by one unit in the reverse clockwise direction (Fig. 13), in this case from 1 to 0. These operations are not part of the invention and will not be described in more detail . It should only be pointed out here that the rack 133 is switched back and forth by one unit with each revolution of the cam disk 54 via any drive, the wheel of the multiplier mechanism 64 just meshing with it being set back by one unit each time. Since at this point in time the tenth wheel Z of the wheels 64 meshes with the rack 133, the tenth wheel Z of the wheels 64 is reset from 1 to 0, with the zero tooth 94 of the tenth wheel Z moving the shift lever 97 assigned to it back from the position shown in Fig. 13 returns to the rest position according to Fig. 12. With the further rotation of the cam disk 54 (Fig. 6), the parts 53, 38, 37, 35, 34, 41, 84 and S5 in the opposite direction of rotation of the arrow 134 and via the control connections 84 , 81, 80 and 85, 82, 80 the switching bridge 79 swiveled in the reverse clockwise direction around the axis 76 from the position according to Fig. 18 into the switching position according to Fig. 14 and the parts 86, 87, 93, 64, 65, 88 , 97 and 120 raised. The switching lever 97 of the tenths of a digit Z influences the switching pawl 103 and via 112 the switching pawl 107 from the rest position according to Fig. 12 into the switching position according to Fig Rest position the remaining distance of a switching step of the slide 73, 75, 64, 65 switched to the left.

As a result of this left-hand switching step of the slide 73, 75, 64, 65, the multiplier gear train 64 moves with its hundredth digit H into the plane of the rack 133 (Fig. 22). Because the hundredth digit H of the multiplier gear train 64 is set to 2, the opposite shift lever 97 is controlled from its switching position according to FIG. 12 into the non-switching position according to FIG. 13. As a result, depending on the following two revolutions of the drive coupling 54, 58, two additions of the multiplicand 24.00 take place in positions II and III (Fig. 22) of the product plant 65. The result is the following multiplication picture:

During the second round of the course

venscheibe 54, depending on the rack 133, the hundredth wheel H of the multiplier gear train 64 is reset to zero and consequently the corresponding shift lever 97 is returned from its non-shift position (Fig. 13) to its shift position (Fig. 12). Accordingly, after the two-fold addition of the multiplicand 24, the relevant switching lever 97 controls a further left switching step of the slide "73, 75, 64, 65. As a result of this switching step, an empty switching of the slide Ji, 75, 64, 65 is initiated by the following device, the latter for the purpose of switching off of the multi-tipli / der process and automatic activation of the product total:

Empty switching of the carriage 73, 75, 64, 65 at the end of the product formation for the purpose of initiating the project

'duktensummenzuges

If the switching step (Fig. 23) of the slide 75, 73, 64, 65 is controlled to the left as a function of the switching lever 97 of the hundredth place H (Fig. 9) of the multiplier gear train 64, a switching lever 135 (Fig. 9 and 19) -in the ready position for the switching pawl 103. This switching lever 135 is attached on the one hand to the axle 86 and on the other hand to the axle 93. Its forward protruding nose 136 prevents .that it rests on the nose 127 (shown in phantom in Fig. 19) of the control lever 128, during the now following revolution of the cam disk 54, the engagement of the gear trains 64, 65 with the racks 132, 133. Accordingly, the multiplicand 24.00 is not added again in the product gear train 65. A nose 137 of the switching lever 135 controls the switching pawl only when the parts 86, 87, 93, 64, 65, 88, 97, 120, 135 are moved upwards 103 and via 112 the pawl 107 for the purpose of a further left-hand switching step of the slide -Ji, 75, 64, 65.

In the course of this empty switching of the slide y $, 75, 64, 65 to the left, due to the fact that the multiplication of the factors 0.12 χ 24.00 = 2.8800 is ended. Depending on the switching nose 88 "(Fig. 19) of the switching lever 88, a suitable rocker lever (not shown) influences, which acts on the tab ij _a (Fig. 4) of the pawl 17 and swings it out in the reverse clockwise direction, so that the Lock 18, 19 is opened again and the result key 8 returns to the rest position under the action of the spring 14. As a result, the parts 9, 24, 26, 27, 2S, 32, 33, 34 are moved back from the "active position according to FIGS. 6 and 8 into the rest position according to FIGS. 5 and 7. As a result, the coupling 35, 37 becomes again open and the coupling 36, 39 closed and the cam disk 54 comes to a standstill again.

Product total

During the idle step shift of the slide 73>75> 64, 65 to the left, controlled by the shift lever 135, a suitable control device in a preparatory position is simultaneously turned into a brought with the cam 54 rotating cam element, not shown, which at the end of its last revolution in the product formation affects the aforementioned control device such that the same automatically depresses a conventional sum pull key lever 138 (Fig. 3 and 18). This swivels clockwise around the bearing axis 12 and releases a coupling pawl 142 (Fig. 18) of the sum pull coupling 142, 143, 144, which was previously held out of engagement by the coupling wheel 141 by means of its arm 140 (Fig. 3), for the purpose of coupling with the one on the main drive axis 57 seated clutch wheel 141 free. As a result, the total pull coupling 143, 144 and a cam disk 147 connected to it via a claw coupling 145, 146 (Fig. 3) now participate in further revolutions of the main drive shaft 57 in the direction of rotation of the arrow 56. At the beginning of the first rotation, the raised cam section I47 _U (Fig. 18) of the cam plate 147 releases a roller 148 of the roller lever 40. The latter> w pivots under the influence of the tension spring 149 in the direction of rotation of the arrow 134 and moves the parts 41, 45, 84, 85, 79 (Fig. 18), 86 via the coupling 39, 36 (Fig. 4), 34 , 87, 93, 65, 64, 88, 97, 120, 135 as well as a switching comb 150 (Figs. 9 and 19) fixedly arranged on the axis 86 within the area of the product wheel train 65 from the rest position according to Fig. 2 into the active position according to Fig. 18. As a result, the gear train 65 engages the racks 132.

When the sum pull coupling 142, 143, 144 and the cam plate 147 continue to rotate, the roller 148 rolls on the lower part 147 ^ of the cam plate 147. Meanwhile, in a manner not described in detail here, the sum is drawn from that computing point of the product plant 65 which at this point in time (Fig. 23) is opposite the rack S of the rack set 132, via which the product totaling is taking place at the same time. The total of products can also take place via another rack of the rack set 132. The purpose of why, in the present case, the rack 5 ^{1 was} selected for the sum of products will be explained further below.

Depending on the rising ■ curve part 147 ,, of the cam plate 147 now when turning the latter the parts 148, 40, 39, 36, 34, 41, 45, 84, 85, 79, 86, 87, 93, 64, 65, 88, 97, 12Θ, 135, 150 from the effective position according to Fig. 18 is moved into the switching position according to Figs. 6 and 14. As a result the left nose 151 (Fig. 19) of the switch comb 150 controls the switch pawls 103, 107. for the purpose of another? Left stepping of the carriage 73, 75, 64, 65, after which as a result of the rolling of the roller 148 on the unrolled falling part of the cam 147 ^ of the cam 147 return the aforementioned moving parts to the rest position (Fig. 2).

When creating the product, only calculation points I, II, III (Fig. 23) of the product plant 65 corresponding to the value 2.88, so that the product plant 65 has the following setting screen:

0000000002.8800.

It should be pointed out that the first, second and third digit from the left of the product work are not sensed during the total draw, for the reason that the vertical counter 3 _a (Fig. 1) of the paper cart storing the product does not count the number of Like the product mechanism, it has computing points 65. With a correspondingly wider vertical counter, the product total can of course be set up in such a way that these three left-hand points of the product mechanism are also sensed. For this purpose, the leftmost toothed rack of the toothed rack set 132 is selected for the purpose of the product total and a fourteen-nosed comb 150 (Fig. 19) is provided.

In addition to the already described of the Nose 151 of the switching comb 150 controlled switching step of the slide 73, 75, 64, 65 find to the left as a result of the ·. further revolutions of the sum pull coupling 142 to 144 for the time being another five left step circuits of the slide 73, 75, 65, 64 instead of the one after the other from the noses 152 to 156 of the Switching comb 150 are initiated. As a result of the discontinuation of these computing points of the product plant 65 to zero, no zeroing process takes place, and the imprint of this Zeros on the form clamped in the paper trolley 2 (Fig. 1) will also be with the help of any known, not shown device for preventing the Writing zeros in front of whole numbers is switched off.

Due to the five left-hand switching steps of the slide 73, 75, 64, 65, the product plant 65 with the computing point I moved into the area of the rack controlling the zero position .S "(Fig. 24) the rotation of the cam plate 147, the product gear train 65 is inserted into the racks 132, 133, as shown in Fig. 18, and there the engagement for the duration of the rotation of the raised nose 147, the cam plate 147 (Fig. 4) on the roller 148 of the rocker arm 40 is maintained, the arithmetic unit I of the product plant 65 is reset by two units to zero by means of the rack 5 ″ and the value 2 is entered on the one hand in the vertical counter 3 _Ü (Fig. 1) of the paper carriage 2 which stores the product go and on the other hand the Number 2 printed on the form.

Now the cam plate 147 (Fig. 18) controls the parts 79, 86, 87, 93, 64, 65, 88, 97, 120, 135-, 150111 the upper position according to Fig. 4 by means of its rising cam part i47j, whereby the Nose 157 (Fig. 19) of the switching comb 150 another left switching step of the carriage 73, 75, 64, 65 is initiated and this switching step is completed when the above-mentioned parts return to the rest position according to Fig. 2. As a result, the computing point II of the product plant 65 moves into the plane of the rack 5 (Fig. 25). 105 Meanwhile, the paper trolley 2 was automatically switched by an additional switching step with the help of an automatic comma skipping device in order to skip the decimal point of the vertical counter 3 _a . These operations are known and will therefore not be explained in more detail here.

The computing site II which according to fig. 25 is in zero setting position, is now reset in response to the further rotation of the cam disc 147 in the above-described manner to eight units to zero and the value introduced the Vertikalzählwerk concerned 3 _a 8 in. And the corresponding number is printed on the form. Now from the nose 158 of the

Switching comb 150 another left switching step of the carriage 73, 75, 64, 65 is controlled so that now the computing point III of the product plant 65 in the plane of the rack. stands (Fig. 26). In principle, the processes just described are repeated here, but the left stepping carriage is controlled by the nose 159 (FIG. 19) of the switching comb 150. The zeroing process then takes place in the place to the right of computing point III of the product plant 65, and after a further left ^{stepping of the carriage 1} S 73>75> 64, 65 controlled by the nose 160, the zeroing process takes place in the remaining right 65 instead. Due to the present product, however, these two right computing points of the product plant 65 are already at zero, so that here only left stepping of the slide 73, 75, 64, 65 are controlled on the one hand by the nose 160 and on the other hand by the nose 161 of the switching comb 150 . If the vertical counter 3 _U (Fig. 1) storing the product has only two arithmetic digits to the right of the decimal point, the aforementioned two right arithmetic units of the product unit 65 are probably set to zero, with the value neither being written nor entered in the aforementioned vertical counter 3 _e . This device is known and therefore not shown and described in detail here.

After the sum of the products has been pulled, the lock 162, 19 holding the sum pull key lever 138 (Fig. 18) in the printed position is automatically opened again, and the parts 138, 140 are moved back into the rest position according to Fig. 2 by the spring 164. As a result, even after the total pull clutch 142, 143, 144 and the cam plate 147 have been fully rotated, the clutch pawl 142 is again disengaged from the clutch wheel 141 of the main drive shaft 57 by the arm 140, so that the clutch 142, 143, 144 and 147 comes to a standstill again. At the same time, an arm 165 acts, which, when preparing the machine for multiplication, moves from the rest position shown in solid lines in Fig. 3 to the active position indicated in the same figure in dash-dotted lines and a spring was tensioned by the power drive of the machine and now at the end of the product sum, by the fact that the spring is released, snaps back into its rest position under the influence of the spring, attached to a bridge 75 of the slide 73, 75, 64, 65 by means of screws 166 (Figs. 3 and 9) Part 167 and moves the carriage 73, 75, 64, 65 against the action of the spring in the reverse direction of the arrow 119 back into the starting position according to FIG. 9. The pawl 107 ratchets over the teeth 116 of the bridge 75 and then lies down again in front of the left side surface of the left tooth 116, as is shown in Fig. II. The force of the spring acting on the lever 165 (Fig. 3) overcomes the force of the spring 118 (Fig. 9) of the slide γ ^, 75, 64, 65. Since the lever 165 (Fig. 3) is already in front of the multiplying from its rest position into the operative position (dash-dotted gekeinizeichnet) and it has been banned in this operative position, its hereby tensioned spring exerts no influence on the carriage ¹ J ^, 75, 64, 65 (Fig. 9), so dal! the slide 73, 75, 64, 65 can be shifted step by step to the left unhindered under the influence of its spring 118.
