Description

159573 I.

The subject of the main patent is a multiplication machine, during its training use is made of the arithmetic fact that the value of a product remains unchanged if one multiplies one factor by a number at the same time and divide the other factor by the same number. The machine technology This arithmetic rule is applied to the machine of the main patent in such a way that each factor has to be solved Multiplication problem continued multiplied by 2 and taking the other factor into account of whole numbers only by 2

is divided, and that partial products of the factor underlying the doubling additive are combined with one another, "or, to put it more precisely, that the setting value of a factor recording adjuster continued to be multiplied by 2 and, if necessary, reduced by 1 to bring it to an even number Setting value of a second factor adder is divided by 2, and that the setting values (partial products) of the Duplicating adder (multiplicand adder) requires one for each case decreasing by 1 with the halving adder (multiplier adder)

Halves 3, ι and 2, ι ; with 3 and 2 only one halving size, namely 1.

Unnecessary machine games are therefore carried out, if like with machines According to the main patent, the same number of machines ί, - ^ games are always used to solve every problem is performed.

t%} The present invention brings about

that of the main patent the new that 70 10 Decomposition of a continued halving ^ ^ | e in one according to the principle of the head

be transferred to a result adding unit, the latter then containing the product number, if the setting value of the multiplier adder, possibly reduced by ι has decreased to zero.

With the machine of the main patent was in the interest of a faster achievement of the additional; Status at which the setting value of the ^

multiplier adder reaches the value 0,

multiplier to be subjected to several factors with a smaller number of digits, for which the machine has separate multiplications side by side, d. H. simultaneously carried out, the results of which are finally combined with one another in the appropriate place assignment became.

With one for a certain number of digits of the person involved in the halving machine games Factor (multiplier) specific machine, e.g. a machine, which the execution to allow multiplications with a six-digit multiplier, was the device according to the main patent so made that the machine does every task it is presented with regardless of the size of the multiplier executed a very specific number of machine games in a fixed order, namely the maximum number of machine games that can be performed when solving a problem with the number of multiplier digits, for which the machine is calculated, may be required. The number of machine games required in the individual case depends on the size of the multiplier, and not only on the number of digits, but also on the the set of digits contained in it. If z. B. with a to a six-digit Multiplier calculated machine a task is to be calculated in which the multiplier only has three digits, and if so then the machine, as in the main patent intended for breaking down the multiplier +5 into several sub-multipliers smaller Number of digits is set up, then it is clear that you can get by with fewer machine games, if the decomposition of the multiplier is carried out in such a way that one three-digit Multiplier three single-digit multipliers can be made as if the decomposition z. B. so happens that a two-digit and a single-digit factor is formed.

The fact that the combination of digits in the multiplier also plays a role is readily apparent when one takes into account the halving games required for single-digit multipliers. With 9 and 8 there are three halving sizes corresponding to the halves to be formed 4, 2, 1; at 7 and 6 as well as at S, 4 two halving sizes for the 1 patent constructed multiplication machine provides means to carry out the solution of a given multiplication problem in such a way that each time the smallest number of doubling and conversion processes is required. To achieve this purpose, devices are provided in the machine according to the present invention in order to scan the multiplier for its digit components before starting the calculating machine games and each time it is determined that it contains digits in four or more digits, the multiplier digits as two-digit multipliers in the machine to introduce. After this preparation, the operations in the machine proceed in the manner described in the main patent with the exception that the doubling and halving machine games are completed when all sub-multipliers are brought to the value 0, which can be the case after a changing number of machine games. If the removal of the multiplier results in that it contains 95 digits in less than four places, then the multiplier digits are treated individually as multipliers, in that each multiplier digit is transferred to a multiplier adder, and there are separate product sizes for the multiplications with the receive single-digit multipliers, each of which is the product of the multiplicand by one of the multiplier digits. The sequence of the arithmetic operations is illustrated in FIG. 14 for the multiplication tasks 326 × 25. Thereafter, the digits of the multiplier 326 are each transferred to one of the multiplier recording adders A, B and C , while the multiplicand 25 is transferred to the multiplicand recording adapter. In this case, the position shift connections must be made in such a way that during the transfer of the partial products into the end result only a shift of one place takes place.

In Fig. 15 is the flow of the arithmetic operations when solving the multiplication problem 3SX15, where the multiplier 35 contains only two digits. In this case, each multiplier digit becomes one

of the two multiplier recording adders B and C , and the calculation is carried out in the usual way when using the three adders. However, since only two partial products are obtained in this case, only a single uniting machine game is required to connect these two partial products. The device, which before receiving the

■ ο Arithmetic machines-the scope of the Determines the multiplier, in this case eliminates what is usually required second partial product unification machine. In Fig. 16 is finally the calculation process for the case of a single-digit multiplier is also shown. In this case, the machine becomes automatic when the multiplier is deducted so placed that the partial product association machine games are omitted at all, there only a single product intake adjuster receives a value setting. In this case it can the printing takes place directly from the product adder as soon as the setting of the Multiplier adder has decreased to zero.

The invention, like the invention of the main patent, is particularly applicable in the case of machines controlled by counting cards, determines which ones are used in such machines usual devices for the card transport, for the sensing of the counting points and the transfer of the sensed values in addition units and with the addition units assigned extraction devices are provided for values set therein, which the introduction of extracted values into adding units and their written definition allow.

Since the present invention, compared to the invention of the main patent, only concerns special measures to avoid machine backlashes corresponding to the variable multiplier values in the series of tasks to be solved, explanation ^{1 should be used} in conjunction with to facilitate understanding of the innovation brought about by the invention the same machine, which is shown in the documents of the main patent and which is only provided here with the necessary additional card sensing and control devices to control the number of computer games depending on the numerical values of the multiplier.

Before moving on to the establishment of the only in a working circuit diagram and in its main parts The punch card machine shown in the drawing is entered into, the work processes peculiar to the invoicing process using a numerical example already dealt with in the main patent, for which the task in the counting card shown in FIG is perforated, will be explained in connection with FIG.

The task card, in which the number 596329 is punched in the multiplier field MP and the number 1580 in the multiplicand field MC dk, is first moved by the card transport device of the machine so that the card fields containing the multiplicand and the multiplier are sensed by sensor brushes, with the introduction of the sensed number sizes in the multiplier MC and in three multiplier adders A, B and C , each of which takes up two digits of the multiplier size, these two digits forming small multipliers for which the multiplication calculation is separated by the machine

is carried out. In the numerical example assumed, the multiplicand is multiplied under the influence of the adder A with the multiplier 59, under the influence of the adder B with the multiplier 63, under the influence of the adder C with the multiplier 29 correct job assignment is ensured. In the machine games following the introduction of the number quantities sensed by the task card into the multiplicand and the multiplier adders, it is important, according to the guiding principle of the invention, to repeatedly double the multiplicand value and repeatedly halve the multiplier sub-quantities in the adders A, B and C. Halving is carried out in such a way that from each amount in the adders A, B and C a number is subtracted which is equal to half of its value, provided that the number is represented by an even number, or which is equal to half of next smaller even number is when the number in the adder is an odd number. This subtraction is carried out in accordance with the machine by adding the corresponding complementary values.

The increase in the original multiplicand amount, which was transferred to the MC adder, is carried out in such a way that the respective setting value in the adder is doubled. The doubling of the setting value is shown in FIG. 11 by downwardly directed, arcuately curved arrows, the tips of which are directed towards the next line. The halving of the setting values of the adders A, B and C is shown in the same way as the doubling by arrows pointing downwards in an arc. Transfer processes from the MC adder to one of the other three adders = ΐΐ, ± |: 2 and # 3 are represented by broken arrows, which lead from the column in the drawing, which is overwritten with MC , to the columns overwritten with sii, # 2 and # 3 The broken arrows each point to the adder into which the amount in the MC adder is transferred.

As already explained, the machine performs three separate multiplication calculations side by side, with a partial multiplier for each of these multiplication calculations applies, which is formed by two multiplier digits. So the multiplication calculations become three partial products for the product to be calculated, which is later combined to form the end product will. In order to explain the calculation processes, it is considered sufficient if for the one shown in FIG. 11 Numerical example is explained in particular how the product of the two Digits 2, 9, which are set in the multiplier adder C, formed partial multiplier with the multiplicand 1580 is obtained.

During the second machine game, the multiplicand value 1580, which had been introduced into the multiplicand adding unit MC , is taken from the adding unit and reintroduced into the same, so that the setting value is doubled. The number 29 set in the multiplier adder C monitors the introduction of the number 85 into the C adder, which is the nine's complement of 14, ie half of the even number soft is the smaller even number next to the odd multiplier setting 29. The adder C has only two digits, so that in the same the tens transmission device for the tens is ineffective. Before the doubling machine game and the halving machine game going on at the same time are carried out, the ones place of the adder C is sensed to determine whether there is an even or an odd number at this point. If the sensing shows that the units place of the adder C is an odd number, as is the case with the assumed numerical example. Power connections are then "made which have the effect that the amount available in the adder MC is transmitted to the adder ^ 3 simultaneously with the reintroduction of the amount in the adder MC itself. It is so because 29 is an odd number, the multiplicand During the second machine cycle it is transferred to the adding unit # 3 and at the same time to the adding unit MC ; at the same time, the setting value 29 is halved in the specified sense, i.e. a reduction to the amount 14. After no the second machine game, the adding unit C therefore contains the setting 14, the adder MC the setting 3160 and the adder + t3 the setting 1580.

During the third machine game, the that the processes \ repeats, d. H. the amount in the adder MC, which is now is, is transferred again to the adder MC, and the setting value 14 of the adder C becomes additive by introducing the complement of half the setting value, i.e. H. the number 93, to the half 07 of the setting

brought value. Since the im. Multiplier adder ^ C- standing Size 14 is an even number, so no transfer operation between the adder and the adder MC occurs if: 3. It should be noted here is that if there is an even number in the adder C, then this adder the Ten's complement of half the setting value is introduced, while in the case of an odd setting value in the multiplier adder C the amount introduced into the same is the nine's complement of half of the next lowest even number. After the third machine game, the number 7 is in the adding unit C, the number 6320 in the adding unit MC and the number 1580 in the adding unit ^ 3.

In the fourth machine game, the amount in the adding unit MC is doubled again. Since the uneven number 7 is now in the adder C , the setting value of the adder MC, ie the value 6320, is also transferred additively to the adder # 3. The nine's complement of half of 6, i.e. 96, is added to the adder C , whereby the setting of C is reduced to 03. The fifth and sixth machine game are repetitions of the fourth machine game, since the adder C contains the odd number 3, which is reduced to the odd number 1 in the fifth machine game, so that the same conditions exist for the fifth and sixth machine game as for the fourth machine game. So it also takes place during the fifth and sixth Masehinen-. play a transfer from the adder MC to the adder # 3 in connection with the doubling of the setting of the adder MC. At the end of the sixth machine game, the setting of the adder C has become ο, while the adder MC has come to 25380 through continued doubling and that of the adder # 3 has come to 45820 through the transfers made from MC. During further machine games there is no further doubling of MC due to the setting of the adder C to ο.

The amount 45820 in adder # 3 is the product of 29 X 1580 represent.

During the doubling and transferring machine games described for the adders C, MC and # 3, corresponding reductions in the setting values of the multiplier adders A and B as well as transfer meshes from MC to the adders # 2 and # 1 have taken place, with the adder turning off the transfer due to its setting value MC on the adder Ϊ2 and the adder has monitored the transmission from MC to the adder # ι through its setting value. After the seventh machine game the adder contains the product of 59 X 1580 and the adder # 2 the product of 63 X 1580 Numerical example). These six machine games were always carried out by the machine of the main patent. According to the invention, a device is now provided which becomes effective when all three adding units A, B, C have reached the setting zero, and which then brings about the first partial product transfer machine game. If'z. B. with a multiplier 10101 the multiplier numbers are distributed to the three adders A, B, C as in the numerical example discussed above, then each of these adders would have an ι in the ones place, and after the first transmission machine game, the setting would be in all three adders Be reached zero. Immediately after the first transferring machine game from the MC adding unit to the adding units A, B; C the combination of the corresponding numerical values 1580 then contained therein, with a corresponding shift in positions.

The number of component products association machine games then depends on the number of digits in the multiplier. At a double digit multiplier is just a union machine game required, and with a single-digit multiplier this is also omitted.

In "intended for carrying out the invention punch card machine required for the drive of working important parts of energy of the shaft 10 (Fig. 4) is removed, which immediately the motor shaft can be. The sensing of the card is performed at two consecutive Abfühlstellen by upper Abfühlbürsten UB and lower brushes LB, to which the cards R are fed one after the other from a storage container by a pick-up knife 11, which advances each card up to an upper transport roller pair 12, which then feeds them to the further transport roller pairs I3 _a and 13, with them on the upper brushes UB and the lower brushes LB. The shafts of the rollers 13, I3 "are provided at their ends with gears 14, which are driven by the shaft 10 and a gear 16 seated on this via a gear 15. The shafts 13 and I3 "Run around all the time. Through a gear

15 is a gear 17, which loosely on a Shaft 19 is seated, driven via an intermediate gear 18. On the shaft 19 sits a gear 20, which is both the card pick-up knife 11 as well as the first pair of transport rollers 12 drives. There is also a coupling arm on the shaft 19 21 attached, on which a spring-loaded latch 22 is seated for usually by a rotatably mounted at 24 armature 23 of a magnet 25 in a is held in a fixed basic position.

The excitation of the magnet 25 causes the pawl 22 to be released so that it can fall into the driving coupling part 26, which sits on the continuously rotating shaft 19, so that the gear 20 rotates during which the pick-up knife 11 detects a counting card Pushes out the card container and feeds it to the pair of transport rollers 12, which advances the card so far that it reaches the upper of the two layers shown in FIG. 5 by dashed lines. During a second rotation of the transport rollers, the card is advanced so far that it passes the upper set of brushes UB and at the end of this card transport machine game is in the lower of the two positions shown in FIG. 5 by dashed lines. In this position the front edge of the card is on the lower brushes LB. The upper brushes UB cooperate with the transport _{roller pair I3 a} , of which the left-hand roller consists of a series of disks made of insulating material, between which the individual brushes are located. The right-hand roller consists of a series of mutually insulated contact rings, with each of which an upper brush UB _{a is} in contact. The position of the brushes UB is such that they loop over the counting point position o of the counting card immediately before it reaches the lower of the two card positions shown in FIG. 5 by dashed lines. At the lower sensing point, a card lever is provided which controls a card lever contact LCL and closes it when the card passes the lower sensing brushes. During the doubling and halving machine games and also during the transmission, the partial product combination and the end product printing machine games, the magnet 25 is de-energized, so that card transport does not take place during such machine games. To initiate operation after the cards have been placed in the storage container, it is necessary that the machine executes two card transport machine games in order to transfer the first card of the stack into the lower of the two card layers shown in FIG the upper position shown in dashed lines happens. During the third card transport machine game «5, the first card of the stack thus passes the brushes LB , and at the same time the next card arrives in the lower of the two layers shown in FIG. 5 with dashed lines. 7 "

When the hole values are sensed by the brushes UB , the multiplier sensing values are transferred to adding units A, B and C provided in the machine and the multiplicand value is transferred to an adder MC. This is done in the usual way in the so-called HoUerithtabelliermaschinen that when a card hole is sensed in a card column, the adding wheel assigned to the column is coupled to the machine drive by energizing a magnet, which coupling remains in place until a fixed point in time of the machine game, so that every time an adder wheel circuit corresponding to the time of coupling, i.e. the position of the hole being sensed, takes place.

The drive shaft for the adding wheels is denoted by 27 in FIG. 7; this is immediate coupled with the already mentioned drive shaft 10 of FIG. 4, so that they is in rotation as long as the engine of the machine is running. The transmission ratio is such that the shaft 27 at makes one revolution every card transport machine game. Sit on shaft 27 displaceable but non-rotatable coupling sleeves 28, one for each digit an adder. The coupling sleeve 28 is provided with a groove, in wel- «oo rather the end of a short lever arm 29 engages, which is rotatably mounted and with a Block 3 is connected and usually by an armature pawl 31 of an adder magnet 32 is held in the position shown in FIG.

A leaf spring 33 lies against the end of the longer arm of the lever 29 and moves it counterclockwise when the block 30 is released by the armature 31 in the. This movement brings the teeth of the coupling sleeve 28 into engagement with the teeth 34 of a gear 35 which is loosely seated on the shaft 27. When the gear 35 is coupled to the shaft 2j in this way, it sets a gear 36 in engagement with it in rotation and in this way displaces the dial 37 of the relevant digit of the adder. The rear end of the lever 29 can be grasped by a finger 38 towards the end of the machine game.

wherein the coupling is released and the block 30 again through the armature 31 of the Adding magnet 32 is blocked.

The adding magnet 32 is excited at alternating times of the machine game depending on the position of the card hole sensed by a brush UB in the card column assigned to it. The clutch 28, 34 is then engaged, which is released by the finger 38 at a fixed point in time after the counting point locations of the card have been scanned. The hole values of each scanned card are thus transferred to the connected adding units, as is customary with punch card machines.

The gear 35 also drives a gear 39 with a gear ratio of 2: 1, so that the Wheel 39 only makes half a turn for each turn of 35. The wheel 39 carries a pair of brushes 40, isolated from the wheel, of which two are conductively connected to one another Brush one ten contact pieces 41 and the other one contact sheet 42 looped. When the number disk 37 is in its zero position, then it is the one brush 40 in contact with the contact piece 41 No. o, while the other The brush is in contact with the contact sheet 42. Any adjustment of the number disc 37 results in a corresponding adjustment of the pair of brushes 40, so that the a brush 40 is at all times on the contact piece 41, the numbering of which corresponds to the setting value corresponds to the number disc, while the other brush is in contact with the contact sheet 42 at the same time. The commutator-like device 39 to 42 forms a removal device in a known manner for setting values of the number disc 37 or for setting the number disc dependent values and can be used in the implementation of the present invention to control duplication, transmission, Association and Product Printing

4-5 operations can be used, as will be explained in more detail later.

The printing device is illustrated in FIG. 9 and is essentially the same a printing device customary in punched card tabulating machines of the Hollerith type. The one in direct driving connection with the continuously rotating drive shaft 10 (Fig. 4) standing shaft 43 carries a coupling part 44, which thus also continuously circulates. On the shaft 43 is also seated freely rotatable a disk 45, which a spring loaded clutch pawl 46 carries which in engagement with the driving coupling part 44 is able to occur. Usually, an arm 47 disengages the coupling pawl the coupling part 44 held. The arm 47 is under surveillance by one Magnet 48, when excited it releases the coupling pawl 46 so that it is in a recess of the driving coupling part 44 is able to collapse, so that the loose seated on the shaft disk 45 must participate in the rotation of the shaft. The disc 45 is grooved in which engages a pin of an arm 49 which sits on the shaft 50 so that upon rotation the disk 45 of the shaft 50 is given an oscillating movement. On the shaft 50 is an arm 51 firmly attached, which is articulated to a cross head 52, thus with each revolution of the disk 45 an upward and downward movement is issued. With the cross head 52, the type rods 53 are in sliding connection, each type rod under the action of one Spring stands, which it tries to lift, so that the type rods on the upward movement of the crosshead, provided they are not prevented from doing so by blocking. The type rods are provided with a locking toothing 54, the teeth of which on a Pawl 55 go by, with the passing of a tooth of the ratchet teeth with the passage of a Type 56 of the Typgo rod through the pressure position opposite the Pressure roller 57 collapses.

If the type bar assigned to a type bar during the upward movement of the type bar Magnet 58 is excited, then this gives the locking teeth 54 of the type rod opposite pawl 55 free by being connected to its anchor by a Pull wire 59 disengages a pawl 60 cooperating with pawl 55, so that pawl 55 is in the toothing 54 is able to invade. This interrupts the upward movement of the relevant type rod, so that one of the Time of the excitation of the magnet 58 dependent type 56 held in the printing position will. Before the cross head 52 starts its downward movement, the type hammers then stop, so that all The types in print can be printed.

The support shaft 61 (Fig. 6) of the number disks 37 of the adder is grooved in the usual way in the axial direction so that the pawls sitting on the number disks can fall into it and in this way the return of the number disks to their zero position by rotating the shaft 61 can go.

The "shaft 61 carries at one end a gear 62 which is in mesh with a gear 63 which is on the zero

adjusting shaft 64 is seated. A gear wheel 63 is provided for each adding unit, which gear wheel can optionally be coupled to the zeroing shaft in the usual way. At the end of the shaft 64 there is also a gear 65 which can be set in rotation by an intermittently driven gear 66 which is firmly seated on the shaft 67. On the shaft 67 is also located fixed an arm 68 which carries a standing under spring tension pawl 69, which is usually held in the in Fig. Position illustrated 6 by a Klinkarm 70 on the shaft 71 of the armature ¹ J 2 of a magnet 73 sits. The excitation of the magnet 73 causes the arm 70 to be disengaged from the pawl 69, so that the pawl 69 is able to engage the driving coupling part 74 with a tooth. The coupling part 74 is firmly connected to the gear 75 which is in engagement with a gear 76 which is firmly placed on the continuously rotating shaft 43.

The driving coupling part 74 is then in continuous rotation, see above that by energizing the magnet 73 at any time a driving connection with the zeroing shaft 64 can be produced.

The removal device for the multiplier adders A, B and C is illustrated in FIG. As has already been explained, each of these adding units is set up for only two digits, with value setting in the number disks 37 of the adding units being carried out in exactly the same way as was explained earlier for the multiplicand adding unit MC. These adders are also provided with an extraction device for each digit, but the extraction devices are different from that of the U / C adder in that instead of each setting position of the number disc, a contact piece is only provided for two adjacent setting positions. Furthermore, each sampling device is in a way constructed as a twin means, insofar as the to their corresponding gear 39 via an intermediate wheel 39 ;, is a second brush-bearing wheel 39 ,, drives 4O ₁₁ is also a set of contact pieces 41 by grinding the contact brushes _b, but these contact pieces only corresponding setting positions of the associated number disk 37 are provided for the odd numbers, so that electrical contact between the brush 40 ,, and a contact piece 4I ₆ and the contact sheet 42 ₆ is only present when the number disk is set to an odd number.

_{Each of the brushes 40 1} also acts with a pair of contact pieces 41 1. together, »which are arranged so that, when the brushes are in the zero position, the two contact pieces _41c , which are stored separately and insulated from one another, are electrically connected to one another. This contact! pieces form part of the facility, which is used to. determine when the 'multiplier intake adders are all j at zero. The circuits monitored by the contact pieces will be specified later in the explanation of the working circuit diagram of the machine.

The ones place of each adder A, Ii and C is provided with a device for introducing an additional, the so-called volatile 1. This device is shown in FIG. 13, where the conventional ten transfer pin arm 108 is held in the position shown in FIG. 13 by a pawl 109, usually. The excitation of the magnet 110 causes the pawl 108 to be released so that it can rotate clockwise on the shaft 61, so that the pawl, which sits on the arm 108, engages the next tooth 8g of the toothing 112 which is provided on each number disk 37. The usual tens transmission bar 113 then grasps the lever 108 and returns it to the position shown in FIG. During this return movement, the pawl 111 then pushes the toothing 112 and, with it, the number disk 37 by one position.

In the working circuit diagram of the λ ^ machine according to FIGS. 1, ia, 2 and 3, L, CR and TP, with the addition of digits, designate cam contacts which are actuated during the operation of the machine in certain time monitoring. The cam contacts marked with L are effective during ioo of the card transport machine games. The cam contacts labeled TP are effective during the total pressure and zeroing machine games, while the cam contacts CR as well as the current impulse transmitter E are permanently in effect. are located.

Because of the very numerous power connections that dominate the operation of the machine, are electromagnetic relays that control contacts in the current paths, each time next to each of them controlled Contact is shown without regard to the location of the latter, so that each of the various relays is drawn once in Lines in its own Stromverbindimg appear in the circuit diagram and next to it in dashed lines at each of the contacts assigned to him. The relay contacts are with the reference letters the electromagnetic relay with the addition of digits.

For each scoring card except the first, there is a number of machine games carried out, which of the number of digits and the size of the value digits of the multiplier depends. Of these machine games for the individual cards, one is used for the Guide the card past the sensing brushes. This machine game is followed by a changeable one Number of doubling and halving machine games and of transmission machine games, which number can vary between 6 and ι. After these machine games a variable number of partial product association machine games follows, which number fluctuates between 2 and ο. A final product print and Zeroing machine game.

To initiate the operation of the machine, the switch 77 (Fig. 1) is first closed, whereby the motor M is connected to the power supply of the two main conductors. When the motor M is in operation, the various continuously revolving shafts carrying the contact cams CR begin to rotate. Hitting the start button then causes the contact 78 to close, thereby energizing the card transport clutch magnet 25, causing the

, 30 card tapping knife, which then takes the first card from the card storage container the first pair of transport rollers 12 feeds.

At the end of this machine game, the advanced card is in the upper of the two positions shown in Fig. 5 in dotted lines. A second strike of the start button with closure of the contact 78 results in the renewed excitation of the magnet 25, whereby the first card R advances to the lower brushes LB , while at the same time the second card is pushed out of the storage container by the pick-up knife 11.

At this point the lower card lever has closed the various card lever contacts and the machine is in the ready position, the factors of the. to feel the first scoring card. A third stroke of the starter button then causes a further excitation of the magnet 25, whereupon the card is guided past the lower brushes LB. Immediately before this advance of the card begins, the upper brushes UB have sensed the counting point position ο and thereby determined the number of positions of the multiplier and brought about a corresponding setting of the machine. The circuits controlled by the upper sensing brushes UB will be specified in detail later.

When the brushes LB sense the multiplier and multiplicand fields of the card, then circuits are made through the holes in the cards which represent the factors of the task. At this point it should be mentioned that the mechanisms required for a six-digit multiplier are provided in the circuit diagram, while only a smaller number of digits is expected with regard to the multiplicand. This was done in order to avoid unnecessary accumulation of identical parts in the drawing. If the card continues its downward movement after the operation has been initiated and is sensed by the lower brushes LB , then the multiplicand is set in the adder MC . The effective circuits here (Fig. 3) run as follows: main conductor 90, cam contact CR1, card lever contact LCL 5, brush LB, plug connection 91, contact H 2, which is then closed, as will be explained, adding magnet 32 of the multiplicand adder MC.

Corresponding circuits are closed for the transfer of the multiplier to the multiplier receiving adders A, B and C , in which case plug connections 92 to the adding magnets 32 of FIG. Lead multiplier adder via contacts H 3. The contacts Hz and H2t are provided to avoid undesired reverse currents and are controlled by the relay magnet H (Fig. 1). The effect is as follows: When a card passes the brush LB , the relay magnet H is energized as soon as the cam contact L4 is closed. The energization of the magnet H causes its normally open contacts H 2 and H 2 "to close, provided that a card passes the lower brushes. The closure of contact L4 is monitored over time (see Fig. 8) so that magnet H is excited during that part of the machine game during which the card passes the lower brushes, so that contacts Hz and H 3 are then closed, while they are open at all other times. For the purposes of the invention, relay contacts A ι are provided in the plug connections 92 for the multiplier sensing brushes in order to adapt the feed-in circuits to the number of digits of the multiplier. The control of these contacts will be explained later.

If an amount is to be taken from the adder MC and transferred back into the same in order to double the amount in the adder, then a plug-in

IO

Connection 95 (Fig. 3) between the socket 96 of the adder and the relay contact D ι and another plug connection 97 from the contact D 1 to the socket 93 of the same adder.

The closure of contact D 1 produces the following circuit: main conductor 90, wire 98, impulse transmitter E 2, wires 99, contact pieces 41 of a removal commutator set by the adding wheels, brush 40, contact strips 42, socket 96, pintle wire 95, contact Di, pintle wire 97, socket 93, adding magnet 32, main conductor 80. The adding magnet 32 of the adding unit is thus excited at a point in time which is determined by the position of the brush 42 of the removal commutator.

When an amount of the adder AiC in one of the other addition units # 1, # 2, # 3 is to be transferred ,, then a connector 100 from the receptacle 96 of the belonging to the adder MC Entnahmekommutators to the contacts 1 T2, 2T2 and 3 T 2 established as well as further plug connections 101 to the adding magnet 32. If z. B. the contact 1T2 is closed, then there is the following circuit: main conductor 90, wire 98, impulse transmitter E 2, wires 99, commutator contact pieces 41, brushes40, contact strips42, plug-in sleevesego, plug-in wire 100, contact 1Γ2, plug-in wire 101, plug-in sleeve 93, magnet 32, Main manager fVo. Magnet 32 of adder # 1 is thus excited in accordance with the amount in adder MC.

If the partial products in the adders # 1, ^ 2 or # 3 are to be combined with one another, then a plug connection 102 to the contacts 2 G 2 and a plug connection 103 to the contacts 1G2 are established. Further plug connections 104 and 105 are made from these contacts to receptacles 93 corresponding digits of adder # 3. If the contacts 2 G 2 are closed, then the partial product combination circuit corresponds to the transmission circuit described and goes from the contact strip 42 of the units digit of the adder 4 £ i via the wire 102, the contact 2 G 2, the wire 104, the socket 93 of the ten thousand digit of the Adder # 3 and from it via the adder magnet 32 of this digit to the main conductor 80.

If a contact 1 G 2 is closed, then current flows from the connected contact strip 42 of the setting value extraction device in the units place of the adder # 2 via the wire 103, the contact ι G 2, the wireless, the receptacle 93 to the hundred place of the adder # 3 and by winding the adding magnet 92 at this point to the main conductor 80.

In the plug connections 104, 105 there are relay contacts B 1, which are controlled according to the number of multiplier digits and regulate the correct assignment of digits to the transmitted sub-products.

When the calculated end product is to be printed, the contact is closed, and if the plug connections 106 and 107 are present, the following current paths come from the contact strip 42 of the units position of the removal commutator ^ f 3 of the adder # 3: contact strip 42, pintle wire 106, contact Z ³ 5, pintle wire 107, pressure magnet 58 of the ones place of the adder, 'main conductor 80.

It has been briefly explained above how the various duplication, transmission, Partial product association and product pressure circuits come about, and it is shown in Fig. 3 how the connectors for a single digit each Adding mechanism are to be produced. Similar connections are of course also for ^ ie other digits.

It is now to be described, such as from one of the adders A, B or C taken from a corresponding amount, and after 9 "its complement value is introduced again. This will be explained with reference to the adder A, in particular, the processes which, however, in the same Also play with reference to the adders B and C. The number sizes in the tens place of the adder A are taken after the nine's complement of half their value if the number is an even, or after half the number reduced by ι if the number The working circuits are best understood in connection with a specific numerical example. It is assumed that the brush 40 of the tens digit of the extraction commutator of the adder A is at 8. If the impulse transmitter E ι then rotates during a transmission machine game, then the following circuit occurs established: main conductor 90, contact piece 5 of the impulse transmitter J51, attached to this closed wire 115 No. 5, wire 116 to contact piece 41 «No. 8, 9, brush 40, contact strip 42, socket 117, pintle wire 118, contact D 2, which is closed during the doubling processes, as will be explained, pintle wire 119 , Adder magnet 32 of the tens, main conductor 80. The current impulse occurring at time 5 of the machine game causes the introduction of a 5 in the tens of the adder, and this 5 is the nine.

1 43

! complement of half of 8. If the brush 40 had been on 9, then a 5 would also have been transferred to the adder ^. If the number 59 is set in adder A in connection with the solution of the above-mentioned multiplication problem 596 329 χ ι 580, then a 5 would be in the adder's tens and this would result in a 7 being introduced in the tens would.

The contact pieces 4I _{0 of} the units are connected by wires 120 to the same wires 115 to which the corresponding contact pieces 4i _{a of} the tens are connected. The wires 120 have interruption points with the contacts K 1, which are usually closed. If during a broadcast machine game

ao a contact K 1 remains closed, then the amount withdrawn from the ones place is reintroduced into the ones place in the same way as it was just explained for the tens place. Therefore, if the brush 40 of the units position is on 8, then the following lead-in circuit is closed: main conductor 90, impulse transmitter Ei, wire 115 No. 5, wire 120, which is furthest to the right in Fig. 1, contact Ki, - contact piece 4i _fl no. 8, 9, brush 40, contact strip 42, receptacle 117, pintle wire 118, contact D 2, magnet 32 of the units digit, main conductor 80. If the tens digit of the adder is an odd number, then the contact K ι is open, the Contact K 2, on the other hand, is closed, so that the contact piece 4i _s belonging to the ones place is connected to the wires 115 via a group of wires 121. The contact piece 4i _ß No. 8, 9 of the ones place is completely switched off when the contact K 1 is pffen, since at this point a contact K 2 is not present at all. The wires 121 connect the contact pieces 4i _ß the ones place with wires 115, which correspond to the complement of the number in the place, increased by 5, if_ in the tens place is an even number.

If, on the other hand, there is an odd number in the tens, then the connection with the wires 115 takes place according to the complement ^{value of half of the next lower even number, increased by 1} 5. If, for example, the brush 40 of the ones digit is set to 6 and if the contact Kz is closed, then the lead-in circuit runs as follows: main conductor 80, adding magnet 32 of the units position, contact D 2, plug connection 118, socket 117, contact strips 42, brush 40, contact piece 4I ₀ No. 6, 7 of the units position, contact Kz, wire 121 , No. I wire 115, impulse transmitter E 1, main conductor 90. Therefore, when the brush on the one's digit is on 6 or 7, a circuit is made which results in the introduction of a 1 if the tens is an odd number.

The contacts K 1 and K 2 are switched under the influence of a relay magnet K , which is energized when there is an odd number in the tens. The removal contact pieces 41 j are used for this purpose, and since the brush 4o _a , which loops over the contact pieces 4I ₆ and the contact strip 42 ^, is set to one of the contact pieces 42 ^, the following circuit is established: main conductor 90, cam contact CR 4 , which closes after a value has been introduced, relay contact F 3, which .sich closes during a card transport machine game, contact _{strip 42 δ} , brush 40 _a , odd-numbered contact _{piece 41 b} , relay magnet M, relay K, wire 122, main conductor 80. The magnet M closes contact Mi when it is energized and thereby establishes a holding circuit which goes from main conductor 90 via cam contact CR2, contact Mi, relay windings M and K, wire 122 to main conductor 80. The relay magnet K is so excited at the end of the card transport machine game after ¹ an introduction is made, and is kept energized throughout the introduction of the next interval machine game, bisecting, doubling and transfer operations during which take place.

After values have been introduced, contact CR 2 opens and at a later point in time in the machine game, contact CR4 closes again to enable the new amount in the adder to be sensed, and if the tens is still an odd number, then the relay magnet K is energized again, while when an even number is set in the tens, the circuit is not closed, so that the contact K1 remains open.

The contact pieces 41 j of the removal commutator for the ones place of the adder A control the relay magnet iT, which in turn controls the contact 1T2 of FIG. 3, which, as explained, closes the transmission circuits from the adder MC to the adder # 1. As has already been explained, the transmission takes place every time there is an odd number in the ones place of the adder A. If the brush 4o _a strikes one of the odd-numbered contact pieces 4i ₆ , then a circuit is closed each time. This current

circle runs as follows: main conductor 90, cam contact Ci? 4, contact F 3, wire 123, contact piece 4i _{6 of} the ones place, brush 40 ₀ , contact _{strip 42 6} , relay magnet N, magnet ι T ₃ wire 122, main conductor 80. This circuit is closed at the same time with the Eiregerstromkreis of magnet K. The relay N closes its contact Ni and establishes a holding circuit via the contact to CRz , whereby the circuit remains closed during the introductory section of the next machine game. Therefore, if both the ones and the tens are odd numbers, then magnets K and 1T are energized at the same time and kept energized together.

To solve the problem, it is necessary, if there is an even number in the ones place, to introduce an additional 1, ie the tens complement of half of the number in the place. For this purpose the relay N is provided with a normally closed contact N 2, and if the number in the ones place is even then the magnet N remains de-energized, as has already been shown. Near the end of each machine game joins the N ¹ ockenkontakt CR 3, after previously the Nocken'kontakt CR has concluded 4, and there is the following circuit materialize: the main conductor 90, cam contact CR 3, contact N 2, relay Magnet R, magnet 110 to Introduction of the volatile 1, main conductor 80. The relay magnet R closes its contact R 1 and thereby establishes a holding current path via the cam contact CRj , whereby the circuit is maintained until the next machine game and in this way the mechanism controlled by the magnet 110 is properly effective to introduce a 1 with the assistance of the tens transmission mechanism of the ones digit. If the number in the ones place is odd, then the closure of the contact CR 4 to excite the magnet N has taken place and the opening of the contact A ^r 2 has been initiated before the cam contact CR 3 closes, so that with an odd number in the One's place of the ten switching magnet 110 is not effective.

The circuits for the multiplier adder A have already been explained. Exactly the same circuits can be used for the addition units B and C , so that they do not need to be specifically described. A special set of contacts CR 2, CR 3, CR 4 and F 3 is also shown in the circuit diagram for each adder B and C. Of course, only a single set of these contacts could be provided for the three adders A, B and C.

It is now still to explain the device, which is used to monitor the course of the machine games to -erfget for the implementation of a multiplication calculation according to the teaching of the invention! to have. The relay magnet labeled D in FIG. 1, which controls the doubling circuits, is energized when the cam contact CR 9 closes during each machine cycle, provided that the contacts LCL 6 and Fi are closed. The contact Fi is controlled by a relay F (Fig. IA), which is with the specific contacts 41 _c of the sampling device of the MUI tiplikatoraufnahmeaddierwerks A connected together. If the separate contact pieces of contacts 41 _{e are} bridged because zeros are in the relevant digits of the associated multiplier recording adders, then the following circuit is created: main conductor 80, wire 130, contacts 41 _c connected in series of adders C, B and A, contacts CR 8, LCL 4, relay magnet F, main conductor 90. This circuit is closed when the cam contact CR 8 closes, which occurs after each machine cycle begins. When the Multiplieraufnahmewerke are all on XuIl, the magnet F is excited and it is its contact F 3 closed, creating a holding circuit for. the relay comes about, which runs via the cam contact TP 7.

The closure of the relay contact F2 (Fig. 1) simultaneously causes the preparation of the following circuit, which is closed when the cam contact CR 10 closes at a later point in the same machine game: main conductor 90, contacts 2 GI, P 3, Ci? 10, Y2, relay magnet ι G, contact LCL 3, main conductor 80. The excitation of the magnet 1 G enables a partial product combination process in which the partial product in adding unit # 2 is transferred to adding unit ± P3. The magnet 1 G closes its contact 1 G 5 when it is excited and thereby establishes a holding circuit via the cam contact CR 13. The magnet 1 G also closes the contact 1 G 6, so that the following circuit is closed when the cam contact CR Ii closes during the initiated partial product combination circuit: main conductor 90, contacts CR 11, P 4, 1 G 6, relay magnet 2 G, main conductor 80 The excitation of the magnet 2 G causes the contact 2 G1 to open, whereby the circuit for the magnet 1G is interrupted and the circuits for the partial product transfer from the adding unit 1 to the adding unit 3 are established. The contact

748057

2G $ of the relay 2 G creates a holding circuit via the node contact C /? I4, and the contact 2 G 6 prepares a circuit which, when the contact Ci? 12 is closed, so that during the last part of the second Teilproduktverein igungsmaschinenspiels a circuit comes about which from the main conductor 90 via the contacts Ci? 12, 2 G 6, the relay winding P

ίο runs to main manager 80. The relay P opens the contacts P 3 and P 4 when it is energized, so that no partial product transmission circuits can come about while a connection is made from the end product adder 3 to the pressure magnet 58. Contact P 7 forms a holding circuit for relay P via contact TP 5.

The doubling relay magnet D is thus excited during each machine game that follows the card sensing machine game until the setting of the multiplier recording adders A, B and C has gone down to zero, whereupon the relay magnet Y is excited and prevents further doubling machine games and initiates partial product transmission machine games by exciting the relay 1 transmission machine games . Subsequently, the relays 2 G and P are energized in successive machine mirrors, and when the switch 141 is closed, the pressure and zero setting clutch solenoids 48 and 73 are energized, so that the end product is printed and the various adding units are set to zero will. The closure of the contact TP 1 then causes the card transport clutch magnet 25 to be energized again, so that the next card is advanced and the factors of a new task are introduced into the machine by the brushes LB.

A relay contact E 2 (Fig. 1) is provided which, when it closes, causes the relay magnet P to be excited when the relay contacts Y 2 and 1 G 5 are closed. The excitation circuit for the magnet P runs as follows: Main conductor 90, contacts 2 G 1, P 3, Ci? 10, Y2, ι C-5, E 2, relay P, main conductor 80. When the contact £ 2 is closed, the relay magnets 1 C and P are both energized and a holding circuit for the magnet P is established. The magnet P, however, opens the contact P 3 when it is excited, so that the holding circuit for the magnet 1 G via the contact CR 13 is not established. Accordingly, if the contact £ 2 is closed while Y2 and CR 10 are closed, only the magnet P becomes effective for the following machine play. Contact E2 is always closed if the multiplier contains only one digit, as will be explained later.

A relay contact C2 is also provided which, when it closes, causes the relay magnet P to be energized immediately after the first partial product unification machine game, 90 that the second partial product unification machine game is suppressed. This circuit is as follows: main conductor 90, contacts CR τι, Ρ 4, ι G 6, C 2, P relay, the main conductor 80, so that the magnet P is energized simultaneously with the magnet 2 G. The magnet P establishes a holding circuit and opens its contact P 8, so that the holding circuit of the magnet 2 G is not effective during the next machine game. The contact C 2 is always closed if the multiplier only contains digits in the units and tens, in which case the second partial product combination machine game is not required.

The upper brushes UB are shown schematically in FIG. 1 and are able to come into contact with the individual contact rings I3 _ß , with a current connection between the brushes UB and UB _{a being established} . In the power connection of adjacent brushes UB and UB _{a there} is a socket 131. For a six-digit multiplier, a plug connection 132 is made from a socket 133 to a socket 131 ″, which is connected to the brushes which sense the highest digit of the multiplier field. Another plug connection 134 is led to the socket 131, which is connected to the brush, which senses the thousand columns of the multiplier field. Another plug connection 135 is led to the socket which is connected to the brush which senses the hundred columns, and a third plug connection 136 is to led to the socket, which is connected to the brush, which senses the tens of columns of the card.

Immediately before the multiplier field is sensed by the lower brushes LB , and when the counting point ο of the card is under the brushes UB , the cam contacts L 3 ", L ^ _b , L ^ ₀ and if then the multiplier only has a single value digit In the ones place contains, while in all other multiplier places there are zeros, then the following circuit is created: Main conductor 80, contact LCL2, socket 133, plug wire 132, socket 131, brushes UB _a and UB, which are connected in series for the hundreds of thousands up to the tens , Pintle wire 136, cam contact L 2c relay magnet E, contact TP 6, main conductor 90. The relay magnet E

when it is excited, its contact Ei ₁ closes, whereby it creates a holding circuit via the cam contact TP 6, which remains in place until the product printing and zeroing machine game takes place. When the magnet E is energized, it also closes the contact E 2, so that when the doubling machine games are ended, the relay magnet P is immediately energized and the product is printed.

If the multiplier contains digits of value only in the units and tens, then a similar circuit is created which contains the pintle wire 135 and the cam contact L 3 ₆ , the relay magnet C being energized, so that upon completion of the doubling machine games and the first partial product union machine game the magnet P is excited and a second partial product unification machine play is omitted. If the multiplier only contains numerical values in the ones, tens and hundreds, then the current runs via the pintle wire 134, the cam contact L ^ _a , the relays A and B and via the cam contact TP 6 to the main conductor 90, the contact Az is closed. The magnet also adjusts the contacts A 1 in relation to the position shown in Fig. Ι a, so that the plug connections, which are normally sensed by the card in the units and tens amounts in the adder C as well as from the hundreds and Transfer the amounts sampled in thousands into the adder B and the amounts sampled from the tens and hundreds of thousands into the adder A , and only the amount sampled from the ones digit into the adder B and the _{amount sampled from the +} o hundred into the adder A. is convicted. The digits of the three-digit multiplier are transferred individually to the three multiplier recording adders in this way. The same process occurs, of course, if the multiplier has fewer than three digits. The relay magnet B, which is excited at the same time as the magnet A , then changes its contacts B1 (Fig. 3), so that the transfer of the amounts which dft in the adders. 1 and 4r 2 stand on the adder ip 3 with a shift by a single digit.
