   The main object of the invention is to provide a tabulating machine having improved operating selectivity and increased utility.

 <Desc / Clms Page number 2>

      together with a simplification and improvement of the mechanical structure for the purpose of imparting additional operating properties to the machine, improving and increasing the efficiency and utility properties that were previously encountered in machines of the type in question,
More specifically, the object of the invention is the production of a mechanical calculating device in which a calculating machine can be controlled from a distance by another calculating machine and in which, thanks to an improved mechanism,

   the machines do not need to operate synchronously although the flexibility of the system allows this synchronism to be achieved.



   The object of the invention is also the production of a device of the type specified in the preceding paragraph in which the means showing data in the two machines can be controlled by operations set differently in time, - which can, if desired, be elec4 tric impulses regulated in time.



   Another subject of the invention is the production of a calculating device in which a calculating machine% controller can be associated, with the command or means of plug connections, with a receiving calculating machine. and wherein time regulated electrical pulses are emitted from the controlling machine to operate the receiving machine.



   The invention further relates to a calculating device in which a calculating machine is controlled from afar by another calculating machine, the two machines being provided with independent drive systems, another object of the invention. invention consists of

 <Desc / Clms Page number 3>

 the production of a machine provided with an accumulator mechanism capable of being controlled by a tabulating machine itself controlled by punched cards carrying data represented by indicator points "
Another object of the invention consists in the production of a device comprising calculating machines controlled from a distance, in which one of the machines

 he machine is a taMratBNK / machine comprising only totalizers. These are controlled in accordance with the data from the totalizers of the first machine and in turn control the printing mechanism of the first machine.



   In the calculating machine industry, devices have already been produced comprising means for transferring numbers or totals from one accumulator to another. These devices were until now entirely mechanical and required complicated arrangements. The transfer operations were reduced to the mechanisms of a single machine and the transmitting and receiving accumulators had to work synchronously.

   In addition, the mechanical complication of such devices was considerably increased when one wanted to selectively transport sums of any accumulator taken, among several others, in one of the machines, to any of the other accumulators of the other machine. and then transferring to the printing mechanism of the first machine the result of the combination of the numbers appearing on the two accumulators.



   A further object of the invention is to achieve

 <Desc / Clms Page number 4>

 there is a selection mechanism responsible for determining, among the accumulators of one of the machines, which one should control the operation of an accumulator of another xth machine.



   The object of the invention is, finally, to provide improved means for transferring totals from one of the accumulators of one machine to one of the accumulators of another machine and then transferring from the second accumulator to the second accumulator. printing mechanism of the first machine the result of these successive transfers.

Figure 8 is a portion of a detail map;

FIG. 10 is a table showing the successive phases of the operation which consists in preparing the printed card of FIG. 9 starting from detail cards.



   In order to enable the detailed description to be followed more usefully, the operation of the special embodiment of the invention shown will be explained here in general; the apparatus will be described in its application to a problem arising in a bank, but it is clear that the invention could just as easily be used in a large number of other commercial establishments and in a large number of establishments. number of other cases.



   In some banking houses, the practice is to issue a punch card for each transaction made between the bank and a customer. This perforated card can receive the customer's account number, the date of the transaction, its amount is an indication which indicates whether the transaction should be debited or credited to the account.

   The complement of the sum can also be perforated in a separate area of the card so that it can be used in tabulating scales. such a card may take the form shown in FIG. 8 which represents the well known card of the ROLLERITH type comprising twelve positions of indicator points. Summer kind of operation is indicated in column K; a perforation appearing in the position "11" of indicator points characterizes a debit card while

 <Desc / Clms Page number 6>

 that the absence of this perforation characterizes a credit card,
Cards are ordered by account number and date;

   at the end of certain determined tabulation periods they are passed through the ordinary printer / tabulator HOLLERITH so as to obtain a total of the various accounts which is ordinarily, and as the case may be, the "total credit; the" total debtor "and the" debtor balance "or the" credit balance "., In the distribution of interest on these accounts it was customary to make the balance of transactions of each day for each account, and to count the interest of the day, then to add the successive interests in order to obtain the balance of the interest payable at the end of the determined period. Until now this was a long operation, requiring skills of calculator and a large number of multiplications of daily balances by interest rates.



   In the present arrangement, a device has been provided for automatically taking the sum of all the daily balances corresponding to the period, which sum multiplied by the interest per day gives the interest for the period. Figure 9 shows an example of this registration; the daily operations are recorded there with the daily balances and the total of the latter. Thus the number 372 represents the sum of the credit balances and 1157 the sum of the debit balances. Each of these amounts can be multiplied by the daily interest rate if these rates are different; the difference in the products will be 1 t interest due to the bank or to the customer, as the case may be.

 <Desc / Clms Page number 7>

 



   The operation can best be explained about a special problem which may be the one to which the drawing corresponds. Assuming you want to get the balance of interest due for all accounts for the period from May 1 to May 18, you sort the cards by account number; in addition each group of cards corresponding to a customer account is sorted xxxx in chronological order.



   Blank cards on which only the date and account number have been stamped are interspersed in the appropriate order for the days when there was no transaction. The machine is arranged in the usual way for automatic operation; the cards are fed one by one and the data is distributed among the various counters as shown in FIG. 10. In this figure the column entitled "card" indicates the data punched in the separate cards. The columns entitled CTR n 1, CTR n 2, CTR n 3, CTR n 4 and CTR n 5 correspond to the counters of the printer tab shown in FIG. 1. The columns entitled CTR-A and CTR-B correspond to the two counters of the secondary machine also shown in figure 1.



   The prepared punch card may take the form shown in Figure 9 where only the totals of the various groups are printed; a more detailed punched card can still be established on which the account items of the separate cards are columned.



   As seen in Figure 10, the first line of the sheet indicates that a credit of

 <Desc / Clms Page number 8>

 50 is punched on the card at the same time as its complement, or 9.950. This number is analyzed by ordinary reading brushes and the number 50 is introduced into CTR n 2 and into CTR n 4, while its complement is introduced into CTR n 5.



  At the same time the account number 73 and the date * xx Xxxxxxx50 are printed directly on the first line of the sheet, as in figure 9. These two numbers are incidentally entered in CTR n 1. Printing of camp number and date and ancillary entry into a counter is effected by the well known group indication process which has been fully explained and described in US Pat. No. 1,757. 123 of May 6, 1930. It will suffice to indicate that after the printing of the account number and the date on the first line of the recording paper, the spacing is removed so that at the end of the tabulation d 'a group of cards the total to be printed under the control of the four counters appears on the same line.



   It will also be noted in the aforementioned patent that the account items introduced in CTR n 1 are not printed as totals.



  As shown in Figure 10, the second card carries the credit number 38 and its complement 9.962.



  These numbers are also entered in counters Nos. 2, 4 and 5. The machine is provided with the well known automatic control mechanism for minor control over the date and major control over the account number. When the date changes, a cycle of transfer operations is automatically initiated. During this cycle the machine searches for

 <Desc / Clms Page number 9>

 which of counters 4 and 5 contains a positive balance and transfers this balance either to counter A or to counter B of the secondary machine,
In the case considered here, the tabulation of the group of cards, for the first day of the fifth month, results in a positive balance Xxxxxxxxxxxx of 88, which is automatically transferred to counter A.

   This transfer cycle is followed by an automatic total printing cycle during which the scale 88 is printed on the register sheet under the control of CTR n 4. The total of CTR n 2 is also printed in the column entitled " daily credit totals-Cr ".



  After the printing of the aforementioned numbers, CTR n 2 is reset to zero, as is also CTR n 1, no printing having been caused by the latter. The machine then resumes feeding the cards of the second group representing the operations of the second day. As indicated, this card represents a debit transaction of 20, a number which is introduced into counters 3 and 4 in its true form while its complement is introduced into CTR n 4, a change occurring again in the number which indicates the date and in the scale.



  The scale 68 in CTR n 4 being still creditable, this number is automatically transferred to the counter A of the secondary element where it is added to the number 88 which already appears there, which gives the result 156.



   A total print cycle follows, during which CTR # 4 controls the printing of the scale 68 on the second line of the paper; CTR n 3 controls the printing of the daily debtor total

 <Desc / Clms Page number 10>

 on the same line. The next group representing day three operations contains a card without perforation. Consequently, no entry takes place, from said card, into one of the number counters. A new change of date causes a transfer cycle during which the scale, 68 is again transferred to the counter A which brings the latter to 224 after which the total printing cycle takes place and the same scale 68 is transferred. found printed on the third line of the paper.

   As there was no actual operation that day, no printing takes place in either of the daily totals columns.



   The entry of the account items representing the transactions of the fourth day is carried out in the same way; the balance is transferred to counter A and the other totals are printed on the paper and so on for the operations of the fifth day which are represented by four cards, each of which carries a debit of 80. It will be noted that ' after the introduction of these four account items in the appropriate meter the account situation has changed from a credit balance to a debit balance of 172. This change is noted by the machine and such a debit balance is subsequently transferred to the counter B of the secondary element; during the following total printing cycle, said debit scale is printed in the last column of paper as indicated.

   The operations corresponding to the remainder of the period are distributed in a similar manner, xxxx according to their nature, and the balance of each day is transferred in succession either to counter A or to counter

 <Desc / Clms Page number 11>

 B next, whether this balance represents a debit or a credit.



   After the transactions for the last day of the reporting period have been printed and the account number has changed, counter A contains the sum of the daily credit balances corresponding to the period, while counter B contains the sum of the balances. daily debtors for the same period. Counters 1, 2 and 3 have been reset to zero and counters 4 and 5 contain the last daily balance and its complement.



  A transfer operation is automatically initiated again, in which the total contained in counter A is transferred to the tabulating machine and entered in the paper column reserved for daily credit balances, as shown in the figure. 9..At the same time, the daily debt balances column receives the number appearing on counter B.



   Following this printing operation the counters of the two machines are reset to zero and thus prepared to begin tabulation operations on the group of cards representing the next account. The final total 372 represents the sum of the daily credit balances this number multiplied by the daily interest rate will give the interest payable by the bank to the depositor for the relevant period. The total 1157 multiplied by the daily interest rate will give the interest owed by the customer to the bank for the same period of time.



  Of course, the difference between the two products will give the amount actually due.

 <Desc / Clms Page number 12>

 



   To simplify the explanation and make the problem more intelligible, the separate cards have been shown with the corresponding perforations. the amount of the transaction and the complement of this number,
However, it is clear that the machine can include mechanisms automatically transforming the amount of the transaction into its additional value, which saves space on the card and only requires the perforation, on a single zone of the card, of the actual value of the transaction.



   In the problem chosen for the explanation, it was assumed that the interest rates applied to credit and debit balances were different. For this reason it was useful to accumulate them separately in two counters A and B.



  But when interest rates are the same one can easily. introduce a mechanism by which. at the moment when an entry takes place in the manner indicated above in one or the other of the accumulators, the complement of this entry can be simultaneously introduced into the other counter, so that the two counters carry the real balances of the sums of daily balances. At the end of the tabulation period, one of the counters will show a true number and the other counter will show the complement of said number.

   The mechanism responsible for choosing the number to be transferred to one of the counters 4 or 5 can be used to choose the positive number to be printed on the paper so that at the end of the period considered a single number is printed on the paper. the sheet records- / * the real nom- trator.

Figures 7c and 7d represent the complete electrical circuits of the printer tabulator.



  The machine is absolutely similar to that which was described in the American patent Daly and Page n 1,762,145 of June 10, 1930 corresponding to the Canadian patent n 286,730 of January 22, 1929, with the exception of the totals and control devices. automatic which will be described in detail later.



  During the addition operations, the machine is driven by a tabulator motor TM (fig. 7c) controlled by a group of circuits 10 controlled by relays and cams. Slitting the totals, the machine is driven by an RM reset motor controlled by a group of contact and relay circuits, the whole of which is designated by 11.



   When the tab motor is running, it brings the ordinary punched tab cards (which have indicator dots arranged differently and representing numbers) first under the upper analyzer brushes UB, and, exactly one machine cycle later, under the lower LB analyzer brushes.

   By means of the group control mechanism, the whole of which is designated by GO, groups of cards, represented by the presence of the same entry in certain chosen columns, can be processed separately, the account items of each group being accumulated. and their total read before the machine begins to operate on the next group of cards.
 EMI13.1
 xL & iBOE7S ACOITNID1ATORS When punch cards pass

 <Desc / Clms Page number 14>

 by the lower brushes, their indicator points instantly close the circuits of the suitable lower analyzer brushes LB so as to excite the counter electromagnets 12 (see also fig.

   7d)
As usual, the time-regulated excitations of the said electromagnets control the mechanism responsible for introducing the data corresponding to the reading of the card onto the counter wheels. When any electromagnet 12 is energized, it causes contact 13 to close so as to energize a printing electromagnet 14 which chooses, for printing, the type corresponding to the input data. In this way, the accumulated account items can be put in columns. The foregoing functions are not particularly part of the present invention; They will therefore not be described in detail because they are well known and have been fully described and explained in the patent referred to above.



   Referring now to FIG. 4, it can be seen that the counter wheels are represented by toothed wheels 15 driven by a shaft 16 under the control of the counter electromagnets 12, as explained previously. As usual, indicator wheels 17 fixed to the wheel; the counter makes visible the data entered on the latter.



   This introduction mechanism is identical for all the counters of the two elements of the apparatus; the electromagnets 12 of counters A and B are shown in FIG. 7b.



   While taking the totals, printing is controlled from counters 1, 2 and 3 by

FIG. 2 shows the printing mechanism which places the type bar 30 relative to the roll 31, so as to bring the suitable type 32 into the printing position opposite said roll.

   The tree 33 of the totals driven by the reset motor RM carries a cam 34 on which rolls a roller 35 carried by an arm 36, which can rotate freely on a shaft 37.



   As the cam rotates, the arm 36 rotates clockwise, thus

 a cleat 38 cooperating with an arm 39 wedged on the shaft 37. A shaft 40 fixed to the shaft 37 is connected, by a system of connecting rods, to a printing cross member 41.



  This is responsible for lifting the type bars 30 synchronously with the totals taking mechanism so that the types 32 successively pass through / roll the printing position in front of the xxxxxxxxxx / 31. But, thanks to the spring-actuated, scissor-shaped hinged device 42, the type bars 30 can be stopped in any position without impeding the upward movement of the cross member 41. The type bar 30 is stopped under the control of the bar. 'a printing electromagnet 14. When the latter is energized, it attracts its frame 43 and thus pulls to the right a take-up rod 44, thus releasing a latch 45 which normally retains a stop pawl 46.

   When the latter is thus released it is actuated by a spring so as to engage between the teeth of the rack formed on the type bar 30. The pawl 46 thus prevents any subsequent upward movement of the bar so as to maintain a type. particular 32 in printing position. The ordinary printing hammers 47 are responsible for pushing the type against the roller ,.



   SECONDARY ELEMENT
The secondary element of the apparatus is shown in fig, ure 1. It comprises counters A and B driven by a motor Si ± (in the same way that the counters of the tabulator are themselves driven) by the 'Intermediate Marble Pulley 50.



  The pulley shaft 50 of the secondary element is connected by a clutch (fi.6) with a shaft 51 carrying switch cams. This clutch is of the type

 <Desc / Clms Page number 17>

 ordinary half-turn shown in U.S. Patent C.D. LAKE N 1,600,413 of September 21
1926, corresponding to Canadian patent No. 247,816 of March 17, 1925. It comprises a driving element 52 fixed to the pulley 53 mounted loose on the shaft.
50.



   The excitation of the electromagnet 54 (not shown in the circuit diagram of FIG.
7a) allows the clutch of the shaft 50 with the drive element 52, and the shaft 51 then makes a complete revolution. The shaft 51 is connected by a gear to a pair of switch brushes 55 and to the associated switches 56. The gear of the brushes 55 is connected with respect to the drive shaft of the counter, so as to rotate synchronously with them. counters A and B of the secondary element.

   The transmitters in question are shown schematically in FIG. 7b, as being associated separately with the upper sections * of the counters A and B. during a revolution of the brush 55, the latter rubs successively on segments 57 which are connected. tees, by wires 27, to the corresponding series of segments 23 of counters A and B. Segments 57 are also connected, by wires 58, with the corresponding wires 27 of counters 4 and 5.



   Returning to Figure 1, it can be seen that the ordinary reset shaft 59 is also responsible for resetting counters A and B by making a single revolution. To this end, the reset motor 60 drives the shaft 59, under the control of a single-turn clutch, the assembly of which is designated by 61 and which is brought into play by the electron.

 <Desc / Clms Page number 18>

 magnet 62 shown schematically in figure 7a TRANSMITTERS FOR PRINTING TOTALS
In FIGS. 1 and 3, it can be seen that the devices responsible for emitting time-regulated pulses (and synchronized with the movement of the type bars so as to choose the type for printing) include a certain number of like mutators arched 70, at the rate of a switch for each of counters 5 and 4.

   With each of the switches is associated a brush system 71, mounted on the shaft 33 of the totals. The transmitters in question are shown schematically in figure 7.



   The brush 71 can make one revolution while printing a total. During the first half-turn, it rubs successively on segments 72 connected with the corresponding series of segments 23 of the counters 4 and 5. The wires 58 also connect the segments 72 to the corresponding series of segments 23 of the counters A and B of the secondary element ,,
From the foregoing, it will be understood that each series of switches 23 of the associated counters receives from a transmitter 70 a printout adjusted in time at the moment when the type corresponding to the segment passes through the print line.



   As explained previously, the transmitters 56 send, during the transfer operations, pulses similar to the segments 23 of the counters 4 and 5, so as to report the readings made on the latter to the counters A and B The pulses in question have a setting

 <Desc / Clms Page number 19>

 in the time different from that of the pulses coming from the transmitters 70 which report to the printing elements the readings made on the counters N 4, N 5, A and B, rendering the operation of the transmitters 56, the transmitters 70 are inoperative and conversely, so that, depending on the type of operation performed by the machine, the pulses suitably adjusted in time are transmitted to the counter on which a reading 6 has been taken.



   CIRCUIT INTERRUPTION CONTACTS
Figure 4 shows a circuit interrupt device which controls the circuits in a manner which will be discussed in connection with the circuit diagram. One of the devices in question is associated with each of the counters A, xx B, N 4 and N 5; it comprises a certain number of contacts with three springs 73 and 74, the common blade of which is connected to the conductive segment 26 of the corresponding column of meters.



   The contact 73 is connected in senna, by a wire 75, with the associated printing electromagnet 14 (see FIG. 7d). the contacts 74 are connected in series, by wires 76. with the corresponding counter electromagnets 12 of the counters A and B.

The shaft 78 (FIG. 5) carries, at its end, an arm 82, at the free end of which is an adjustable button which rests on a lever arm 83 freely pivoting at 84.

   The other arms of the various levers cooperate with a cam fixed on the reset shaft 86 of the tabulator and on the shaft 59 of the secondary element. The shaft 86, as explained in the aforementioned Daly and Page patent, can make a full revolution to reset the counters N 1 to N 5, At the same time as the cam 85 switches the arm 82 by means of the lever 83, so as to turn / the bar ner / xxxxxx 77 clockwise and hook the arm 79 by the latch 80.



   The construction and operation of the interrupt device for counters A and B are exactly similar, with the difference, however, that there is only one contact 87 for each of the columns of the counter \) 'In Figures 7b and 7d, the contacts 87 are connected by cables 88 to the corresponding printing electromagnets 14 of counters n 4 and N 5, GENERAL CHARACTERISAMES OF THE DIAGRAM
CIRCUITS
In tabulating machines of the type in question, systems xx are commonly used

 <Desc / Clms Page number 21>

 cam contacts to control certain circuit operations.



   For clarity of the circuit diagram all cam contact systems which are actuated together and are mounted on common shafts have similar set reference numbers. For example there is a group of contacts designated by P3 P5, mounted on a certain tree; another group designated by L1, L11, L12, etc ... is mounted on another shaft and so on. All cam contacts are isolated from each other as well as from the shaft on which they are mounted. In the diagram, the cams in question have been placed without worrying about their assembly on common shafts, in order to avoid complications in the connections of the circuits.

   Likewise, for the clarity of the diagram, it is necessary to place certain relay contacts at points remote from the coils which control them. In this case the contacts carry the reference letter of their control coil with a letter in index
ADDITION CIRCUIT
We will now explain the circuit diagram as well as the phases of the foil operation of the apparatus for the. preparation of the xxxx / shown in FIG. 9. The recording sheet having been placed in the printing position, the cards are placed in the magazine in the prescribed order; the card representing the first transaction of the period is at the top.



   The circuit shown in Figures 7c and 7 is a modification of the one shown in the aforementioned patent; will refer

 <Desc / Clms Page number 22>

 only those parts of said circuit necessary to understand the present invention.



   When a card passes through the lower brushes, pulses corresponding to the value of the account item (whether it is a debit or a credit) and its complement are intro - picked up in counters N 4 and N 5 If it is a credit, the account item is introduced into counters N 2 and N 4 and its complement into counter N 5. If it is is a debit, the item of, account is introduced into the counters N 3 and N 5 and its complement into the counter N 4
We will now explain how to choose the appropriate counter for receiving the account items in question.

   The plug sockets of the lower LB brushes, corresponding to the field of the card in which the true value of the account item is drilled, are connected to the sockets 90 of a class selector system comprising blade-type contacts. 91 which can be moved under the control of an electromagnet 92. This connection is made by means of plug conductors 93. Another connection is made as shown between the sockets 94 and the sockets 95 of the N 2 meters and N 4.

   The sockets 97 of the contacts in question are connected to the sockets 95 of the counters N 3 and N 5.The sockets with pins of the lower brushes corresponding to the field of the card in which the complement of the account item is perforated are likewise xxxxxxxxxxxxxxxxxxxxx other sockets 90 of contacts 91a and the corresponding sockets are connected to sockets 95 of counter N 5.

 <Desc / Clms Page number 23>

 



   The sockets 97a of the contacts in question are connected to the sockets 95 of the counter N 4,
For this arrangement of the cards, the general operation of the machine is as follows. When a card passes through the lower brushes each of the latter which encounters a perforation situated in the "true values" field establishes a circuit from the distributor of 'impul- / * to the wire of sions 99 (which is connectedxxx xxx 100 xx xx line xxx and passing successively through the wire 101, the common lower brush 102, the perforation of the card, the brush LB and its socket, the connections to plugs 93, sockets 90, upper contact 91 and socket 94, to end up with sockets 95 of counters n 2 and N 4.

   Likewise, perforations existing in the field of 'complements' cause the electromagnets 12 of the counter N 5 to be excited by a circuit starting from the socket of the lower brush and passing through the plug connection 93a, the socket 90 of the contact 91a, upper contact element 91a, sleeve 94a and sleeve 95 of CTR N 5
If, before the analysis of the card by the lower brushes LB, the electromagnet 92 is excited so as to move the elements ^ of the contacts 91 and 91a, by opening the upper contact and closing the lower contact, the same perforations existing in the "true values" field will have the effect, through similar plug connections,

   to excite the electromagnets 12 of the counters N 3 and n 5- and the perforations existing in the field of "complements"

 <Desc / Clms Page number 24>

      will control the electromagnets 12 of the counter n 4.



   If the card is a debit card, there is a punched hole in the "X" position of any column of said card. When the latter passes through the upper brushes, a circuit is established starting from the conductor 103 and passing through the upper brush in question, the wire 104, the cam contact L5, the upper common brush, the perforation "X" the brush UB, the plug connection 105, a socket 106, the contact 107 (momentarily closed at the "X" position). the coil 108 to terminate in the line wire 100 Xxxxxxxx through the wire 109. The interrupting electromagnet 92 is thus energized and brings the contacts 91 and 91a in the opposite position to that shown on Figure 7c.

   But, if the card which passes through the upper brushes does not have a perforation in the "X" position, it is a credit card; the electromagnet 92 therefore remains without excitation during the entire following cycle and the contacts 91 and 91a remain in the position shown in FIG. 7c.

We can notice here that we can make use of a translator mechanism to make the puncturing of the complements unnecessary.

   This mechanism can be of the type shown in US patent application JW BRYCE No. 119,803 of July 1, 1926, corresponding to Canadian patent No. 287,236 issued February 12, 1929 Lais, to simplify the illustration of the present invention there is no has not incorporated the translator mechanism in question.



   AUTOMATTICAL CONTROL CIRCUITS
The major and minor automatic control system used in the present machine will be briefly described so as to show certain selective interrupt characteristics which form part of the present invention.

   The ordinary automatic control electromagnets 111 (FIG. 7c) are provided with ordinary contacts in series, so as to prevent sparks at the analyzer brushes. Each control or command electromagnet can be connected in series by means of plug connections, between any upper analyzer brush and any lower analyzer brush, so as to carry out automatic control from any card column. The automatic control contacts 112, one of which is associated with each of the control electromagnets, are arranged so as to close individually when the corresponding control electromagnet corresponds to the corresponding command. 111 is

 <Desc / Clms Page number 26>

 excited.

   All of them open simultaneously towards the end of each tabbing or columnarizing cycle.



  When the control perforations of the successive cards match under the upper analyzer brushes and under the lower analyzer brushes, all the control contacts 112 which are suitably connected by means of plugs for the. automatic control closes at a certain point in the cycle.



    Conversely, when the perforations do not match, one or more of the contacts do not close. control The xxxxxx / automatic contacts 112 are connected in series and between two successive contacts there is a socket 113, so that any number of said contacts can be used and the control can be divided, -in one point any one major section and one minor section. With such an arrangement, when a change of group occurs in the minor section (i.e. a change of date) there is an automatic transfer cycle during which the account items are transferred to the secondary element.



   Following this transfer, the total is printed under the control of the counters of the tabulator, some of which are reset to zero. When a change of group occurs, in the major section (ie a change of account number) the same process takes place as for a minor change. In addition, after printing the account items from the tabulator counters: the totals are printed from the lap counts, the secondary element, and the whole device is reset ...



   The cam control contact L11 adjusts

 <Desc / Clms Page number 27>

 operation of the machine under major control and the cam control contact L12 regulates operation of the machine under minor control.



  Normally these two contacts are closed, but they open for a moment towards the end of each tabulation or columnization cycle. The contact L11 can, by means of a plug connection, be connected in parallel with the control contact 112 chosen for the major control and the contact 112 can, by means of plugs, be connected in parallel with the control. control contact 112 chosen for minor control. As has been shown the contact 112 is in parallel with the minor automatic contacts 112 numbered 1 to 3 and the contact L11 is in parallel with the other major automatic contacts 112.

   The bypass established on the cam contact Lll by the major control contacts 112 goes from the upper terminal of the contact Lll to the blade of the switch 115, which is connected, by plugs, to one of the terminals of the contacts of major control connected in series. The bypass then passes through the major control xxxxxxxx contacts: -; 112 (the other terminal of which is connected by plugs to the contact 116a of the relay of the upper card lever closed by the cards located under the upper brushes, as long as the major group control is operating) to end at conductor 100 and return to l other terminal of the cam contact Lll. For this operation the switches 114 and 115 must be open, that is to say they must occupy the position shown in dotted lines.

   The parallel connection comprising the major control contact 112 and the cam contact 11 is in series with a major control relay 117, while the conne

 <Desc / Clms Page number 28>

 Parallel xion comprising minor control contacts 112 and cam contact L12 is in series with minor control relay 1180
The major control relay is a rear contact 117a and a front contact 117b, while the minor control relay has a rear contact 118a and a front contact 118b.

   The front contacts of the major and minor control relay contacts directly connect the relay coils to line wire 1030 The main control relay hold circuit starts from line wire 103 and goes through front contact 117b, the control relay major 117, the parallel connection comprising the cam contact L11 and the major automatic control contacts 112, to result in 100 wire of line The circuit will be interrupted to remove the excitation of the major control relay 117, for the opening of the cam contact Lll, at the end of any column setting or tabulation cycle during which one of the major automatic control contacts 112 is not made,

   as a result of a mismatch between the major classification perforations on the perforated control boards.



   The holding circuit of the minor control relay 118 starts from the wire of dxx line 103 and passes successively through the front contact 118b, the minor relay coil 118, the control electromagnet 119 of the reset button and the coils 120 and 125 to terminate at the switch 114. The latter is connected to the line wire 100 by the connections comprising the cam contacts L12 and L11 the minor automatic control contacts 112 as well as the.

 <Desc / Clms Page number 29>

 connection comprising cam contact 111 and major automatic control contacts 112.

   It is therefore obvious xxxxx that a change in the data of the major group removes the excitation of the major and minor control relays at the end of the cycle, while a change in the data of the minor group only removes the excitation of the minor control relay. Of course, the removal of the excitation of said relays opens the front contacts 117b and 118b and closes their rear contacts 117a and 118a.



   The final result of this removal of the excitation of the major and minor control relays is to cause, for the first relay, two reset cycles so as to allow the printing of the successive major and minor totals and , for the second relay, a single reset cycle. The rear contact 117a of the main control relay connects, to the conductor 100, the ordinary control relay 122 of the motor and the control magnet 123 of the reset; le: rear contact 118a of the minor control relay connects the same elements to the conductor 100 via a parallel circuit xx.

   Removing the excitation of either the major control relay or the minor control relay energizes the motor control relay 122 and the reset control solenoid 123, which remain energized until that the major and minor control relays are both energized again. As explained in the aforementioned Daly and Page patent, the energization of the motor control relay 122 opens its contact 122a to stop the tabulator motor and prevents the latter from restarting to o ....... ................

 <Desc / Clms Page number 30>

 therefore the motor control relay 122 again ceases to be energized.

   The energization of the reset control electromagnet 123 closes contact 123a to prevent cam contact P5 from taking control of the reset motor, which causes successive reset cycles. zero until the reset control electromagnet 123 again ceases to be energized.



   During each reset cycle, cam contact Lp1 closes and opens, and immediately after opening, cam contact LP2 closes and opens. The Lp1 cam contact connects the major control relay 117 to the wire. line 103 through the front contact 118b of the minor control relay 116. Therefore, closing the cam contact LP1 only energizes the major relay 117 if the minor relay has been previously energized. Since removal of the excitation of the major control relay always results in the removal of the excitation of the minor control relay, closing of the contacts in question during the first reset cycle has no effect.



   The closing of the Lp1 cam contact. During the first reset cycle, energizes minor control relay 118 again, which in turn re-establishes its hold circuit. If, at this moment, the major control relay is energized with its rear contact open (which happens if there has been a group change in the minor control section only).

   This excitation of the minor control relay, by opening

 <Desc / Clms Page number 31>

 its rear contact 118a cuts off the control relay circuit 122 of the motor and of the reset control electromagnet 123; the contacts 122a and 123a then close, which makes it possible to interrupt the reset to zero and to resume fabulation after a single reset cycle., If the major control relay has ceased to be energized, at the end of the first reset cycle, its rear contact 117a provides a circuit for the motor control relay xxxxxxx 122 and for the reset control electromagnet 123, keeping the contacts open, so as to cause a second reset cycle.

   During this second cycle, the closing of the cam contact LP1, energizes the major control relay 117 by establishing its hold circuit and by opening its rear contact 177a to remove the energization of the relay "for controlling the motor and control 122. the reset control electromagnet 123. The reset is then interrupted at the end of the second cycle and tabulation can be resumed.,
The characteristics of the major and minor controls are not limiting because, if desired, they can be put out of service and the machine can be operated either under direct automatic control or by the operation of the last card.

   If switch 115 is closed, it short-circuits cam contact Lll and puts the whole series of automatic control contacts 112 in parallel with cam contact L12. It also provides for the major control relay a current flow, apart from contact L11 and each of the control contacts

 <Desc / Clms Page number 32>

 automatic 112.

   Under these conditions the major control relay 117 remains constantly energized and the minor control relay 118 controls the machine for direct automatic control,
If switch 114 is closed, a permanent current is also supplied to the minor control relay, so as to keep the latter constantly energized and the machine is prepared for the operation of the last card if. none of the electromagnets 111 are connected in series with any column of upper and lower brushes.



   From the above, it is clear that during the tabulation of the first set of cards, the electromagnets 118, 119, 120 and 125, in the minor control circuit, are continuously energized and the electromagnets 121, 122, 123, 124 and 126 of the major circuit are never energized.



   When there is a change in the number of the minor group, that is to say in the date, the relay coil 118 ceases to be energized together with the electromagnets 119, 120 and 125. It moves. ment of the contact elements 118a and 118b of the relays, so as to close 118a, causes the energization of the coils 121, 122, 123, 124 and 126. The coil 122 opens the contact 122a in the control circuit of the motor d 'drive TM, so as to stop the tabulator.

   The energization of the coil 121 closes its contact 121a so that when the cam contact L1 closes towards the end of the last addition cycle, it is completed.

 <Desc / Clms Page number 33>

 an operating circuit of the secondary element This cycle starts from the conductor 103a (figure 7a) of the secondary circuit and passes successively through the contact 127a of the blocking relay coil 127, the wire 129, the contact 131, the electrical - clutch tro-magnet 52, relay coil 132, wire 133 (figure 7c), cam contact L1, contact pads 121a, wire 134 and cam contact SL1 now closed to end in the conduc - tor 100a.

   A holding circuit starts from conductor 103a and passes through wire 129, contact 131, electromagnet 54, coil 132, contact 132a contact SL1 to end in conductor 100ao
When the electromagnet 54 is energized, the contact 131 opens and the coil 130 is interposed in the circuit.

   The coil 130 closes its contact 130a, so as to complete the circuit of the motor from the conductor 103a, through the contact 130a and the motor SM, to the conductor 100a The motor SM of the secondary element operates manually - holding to drive counters A and B and transmitters 56 also work,
During this cycle, the positive balance is transferred, either from counter N 4 or from counter N 5 to either of counters A or B, in a manner which will now be explained.



  During this cycle, contact SL1 opens to cut off the clutch and engine circuits and bring the secondary element to a standstill., Towards the end of the / cam cycle, the / S12 contact closes momentarily to initiate a cycle of totaling and resetting the calculator. The art circuit of the driver 103 (figure 7c) and passes through the motor RM,

   In the usual way, an ordinary cycle of printing the total and resetting the tabulator is thus initiated in the usual manner. During the cycle in question, the totals are printed as on the first line of figure 9 and the counters N 2 and N 3 are reset to zero. During this reset cycle, the LP2 cam contact closes in order to re-establish the minor control circuit and the tabulation resumes on the next group of cards.



   TRANSFER CIRCUITS.



   Before transferring the numbers from counters N 4 or N 5 to counters A or B, it is necessary to first determine which of the scale counters contains a true number and which contains a complement because only the number true must be transferred. The true scale in question is always indicated by the presence of a "0" in the highest unit order of the counter and an additional one is indicated by the presence of a "g" in the same place. This fact is used in the following manner to effect the transfer of the true balance. In Figures 5 and 7d, the transmitters 70 are provided with a special segment 72a with which the brushes 71 are in contact during the tabulating operations.

   The segments 72a are connected to each other and also to one of the segments 23

 <Desc / Clms Page number 35>

 when the outer reading switches are in the "9" position.



   If it is assumed that CTR N 5 contains a complement, the brushes 24 of the orders of the highest units will be mounted so as to couple the segments 23 corresponding to the "9" with the corresponding conductive blades 26.



   At the start of any minor change operation, the electromagnet 120 (FIG. 7c) ceases to be excited as indicated above and its contacts 120a and 120b come to occupy the position shown on the diagram. figure 7d.



   The electromagnet 126 is also energized so as to close its contact 126a (FIG. 7d).



  Immediately after this closure, a circuit is established starting from the conductor 103 (FIG. 7d) and passing successively through the wire 143, the balai 71 of CTR N 5, the segment 72a, the wire 144, the neighbor of neighbor of pin 23 corresponding to "9" in the order of the units xxxxxxxxxx the highest order, the brush 24, the conductor 26 (which is at "9"), the wires 145 and 146 (figure 7b), the relay 147 , wire 148, contact 126a and cam contact P3 to lead to conductor 100. If CTR N 4 had contained a complement, a similar circuit would have been set up to energize relay 149.



   The energization of the relay 147 (FIG. 7b) opens the contact 1 47a so as to cut off the communication of the brush 55 with the conductor 103a.



  This circuit is kept until contact P3 opens during the next tabulator total printing cycle,

 <Desc / Clms Page number 36>

 
The actual data transfer from CTR N 4 to CTR-A takes place here. The series of brushes 24 of CTR N 4 were during the previous tabulating operations of the machine arranged according to the reading of the data of their associated adding wheels. As a result, one of the brooms of the series rests on a switch oath 23 corresponding to the reading of its motions without saying that the other broom of the series rests on the conductive segment 26.

   The latter is connected to the addition electromagnet 12 of the corresponding order of units of CTR - A, through contact 74 and wire 76 (Figs. 7b and 7d). The CTR-A transmitter 56 which is driven during the operation of the secondary element brings its brush 55 successively to the segments 57 of the switch, so that each of the wires 58 and, consequently, the wire; 27 of CTR N 4 receive a pulse at the time of the corresponding counter.



   When the brush 55 passes over the pad 57 corresponding to the "9", the counter A is in position to be triggered with a view to an input of "9" The circuit starts from the coiducer 103a (FIG. 7b) and passes successively by the relay contact 149a, the brush 55, the pad 57 corresponding to "9", the wires 58 and 27 to lead to all the segments 23 corresponding to "9". of CTR N 4. If one or more switches "9" must be transferred, a brush 24 will be in contact with the segment of the "9" in question and the circuit will extend through the series of brushes 24 and the conductive segment 26 to contact 74 then, through wire 76 , up to the electromagnet 12 to return to the conductor 100a via the cam contact SL5 which

 <Desc / Clms Page number 37>

 is closed during transfer operations.



  In this way all unit ciders which are at "9" will trigger the electromagnets 12 of CTR "A at the counter position" 9 ". The other electromagnets 12 will be triggered in a similar manner according to the arrangement of the series of brushes 24 which corresponds to the reading of the counter.



  So in a single turn of transmitter 56, all data from CTR N 4 can be transferred to CTR-A The same process will take place under the control of transmitter 56 from CTR-B when CTR N 5 contains a true scale .



   Towards the end of the secondary element's cycle of operations, cam contacts S13 and SL4 (figure 7b) close in order to establish a circuit to prepare the tabulator to print the real scale from CTR N 4 or from CTR N 5, as appropriate. If we suppose that CTR N 5 contains the complement, a circuit extends at this moment from the conductor 103 (FIG. 7d), through the balai 71, CTR N 5, the segment 72a, the wire 144, switch segment 23, conductor 26, wire 145, wire 150 (figure 7b), contact SL4, wire 151, tripping solenoid 81-4 of CTR N 4, contact 74a , wires 152, contact 120b and contact LP10 up to conductor 100.



  If CTR N 4 had contained the complement, a similar circuit would have excited the tripping electromagnet 81-5 of CTR N 5, The excitation of the electromagnet 81-4 moves the contacts 74, 73 away from the position shown in figure 7d and contact 74a opens to cut the circuit which has just been

 <Desc / Clms Page number 38>

 described.



   The tabulator then drives, as has already been explained, the total and reset printing cycle, during which the type bar rises to the printing position and the brushes 71 of the transmitter rotate with tree 33 of totals (figure 3). The brush 71 of CTR N 4 rubs successively on the segments 72 of the switch 70, so that each of the wires 27 of
CTR N 4 receives a pulse when the corresponding pe passes through the print position.



   For columns in which the brush 24 is at "9". the circuit starts from the conductor 103 and passes successively through the wire 153, the brush 71, the segment "9". wire 27, segment 23 and conductor 26, contact 73, now closed, wire
75, printing electromagnet 12, wire 154, contact LP4 (now closed) to lead to conductor 100. This way, all types that need to print "9" are placed in front of the roll.

   The other types will be chosen at one time. suitable, in accordance with the arrangement of the series of brushes 24 which corresponds to the reading of CTR N 4, Thus, for a single pass, segments
72. all the types which are to print the total under the command of CTR N 4 are suitably placed in front of the roll, so as to completely print the real scale appearing on the various wheels of the counter. At the same time the totals are printed from CTR N 2 and CTR N 3, in the well-known manner, under the control of Ordinary step cams 18.

   After printing the totals, counters N 2 and N 3 are reset to zero.

 <Desc / Clms Page number 39>

 in the usual way and tabulation starts again on the next group of cards, as indicated above.



   MAJOR GROUP CONTROL
The process of successively tabulating a minor group of cards, transferring the scale to the secondary element, printing the total from the tabulator, and resetting some counters, continues until that there occurs a change in the indication of the major group. When this change occurs, the same series of operations takes place. firstly for a minor group change.



  In other words, the last daily balance is transferred to the secondary element and is also printed in the appropriate column on the register sheet. However, the resetting operation begins with this printing of the total continued during a second cycle during which the sum of the scales of CTR-A and CTR-B is printed and the entire apparatus is reset,
When the major class number changes (see figure 7c). the minor and major relays 118 and 117 both cease to be energized. The incidental excitation of the electromagnet 121 initiates the operation of the secondary element as already explained.

   Removing the excitation of the electromagnet 120 prepares the multipolar tripping electromagnet circuits (Figure 7d) and removing the excitation of the electromagnet 119 allows its opening. contact 119a (figure 7c), so as to interrupt the / reset circuits leading to the electromagnets 155 of the / zero button,

 <Desc / Clms Page number 40>

 / An electromagnet 156, in series with the major control relay, 117, maintains its contact 156b open when energized.

   When this electro-magnet ceases to be excited, it allows said contact to close The electromagnets 121, 122, 123, 124 and 126 were excited during a major group change, the electromagnet 122 interrupting the operation of the tabulator and the electromagnet 126 establishing the balance selector circuits described above.



   Cam contacts LP2 and LP1 (figure 7c) are controlled by the reset mechanism of the tabulator and close / successively for a moment xxxxx xxxxxxxxxx following the reset operations, LP1 closing and opening again, u before LP2 is formed.



   Thus, during the following reset cycle, the printing of a total (which takes place as in the case of a change of minor group), the closing of the contact LP2 completes a circuit starting from the conductor 103 and passing through the LP2 cam contact, the minor control relay 118, the electromagnets 119, 120 and 125 and the switch 114 to return to the conductor 100, in the usual manner. The closing of the LP1 contact remains without / 1 'input. e ect on the circuits before xxxxxxxxxxx / of the minor control release reaction. , because a circuit comprising said contact must be completed by contact 118b of minor control relay 118.

   Thus during this first reset cycle, the electromagnets 119, 120 and 125 are again excited. The electron

 / "and 120b / magnet 120 brings its contacts 12a / (figure 7d) to their other position and the excitation of the electromagnet 125 has caused the closing of its contact 125ao When the contact is closed again at cmae LP10, during the first reset cycle, a circuit is established which starts from the conductor 100 (figure 7d) and passes successively through the contact Lp10, the contact 120a, the wire 157 (figure 7b), the tripping electromagnets 81- A and 81-B, wire 158, contact 125a and wire 159 to return to conductor 103.

   The excitation of the electromagnets 81-A and 81-B causes the closing of the corresponding contacts 87 so as to prepare the totals printing circuits which will be described later, / control Returning to FIG. 7c, it can be seen that ordinary cam contact P5 closes during each reset cycle.

   We will now describe the circuits involved in transferring the reading of counters A and B to the printing mechanism. During the second reset cycle, the emitter brushes 71 of the switches 70 pass again through the segments 72 during the first half of the cycle and successive pulses are transmitted to the wires 58, in the now well known manner, then to the wires. wires 27 of the counter switches% concordance with A and b.

Following the transfer of the sums of counters A and B and while the tabulator returns to zero, the cycle of automatic resetting of the secondary element is carried out as follows:

   During the first cycle of resetting the tabulator, the electromagnet 124 is energized, which causes the closure of its contact 124a (FIG. 7d); later, when closing the cam contact LP9, a circuit is completed from conductor 103a (figure 7a) by wire 162, relay contact 124a (figure 7d), wire 160, contact LP9, thread 161 (figures 7c and 7d)

The energization of the coils 127 and 128 changes the position of the respective contacts 127a and 128a.

   Closing of contact 127b establishes a circuit through the relay coil and clutch solenoid 62 until contact SP2 opens on the reset shaft of the secondary element. Closing of contact 128a completes the circuit of reset motor 60 and this circuit remains established until coil 128 ceases to be energized. But, at this time, the SPI cam contact holds the circuit of the reset. motor and switches it off at the convenient time to stop the components in their rest position

  FONCTIOTT INDEPENDA1iJT DU TABULATEUR
The secondary element can be completely separated from the tabulator and the latter can be used in the usual way to accumulate totals and print them out on record sheets. For this purpose all connections shown schematically as passing through Figures 7a and 7b to Figures 7c and 7d have been assembled in a common cable 170 (see Figure 1) which terminates in a block 171. This block is provided with a number of pins 172 which, when they are inserted in an associd 173 block (mounted on the tabulator), establishes the connections between the two elements indicated on the circuit diagrams., The tabulator also includes various switches which, when operated,
