INVENTOR ATTORNEYS Patented Mar. 11, 1941 UNITED STATES PATENT OFFICE to International Business Machines Corporation, New York, N. Y., a corporation of New York Original application November 11, 1937, Serial No. 173,975. Divided and this application February 15, 1939, Serial N0. 256,526

9 Claims.

This application is a divisional application of the parent application Serial No. 173,975 filed November 11, 1937, and is restricted to the disclosure of certain features of the invention disclosed in the parent application involving improvements in printing mechanisms.

The main object of the present invention is to provide means under control of line selection designations of a tabulating card to select the line on which data is to be recorded.

The present invention finds particular utility in a machine devised for automatic accounting for transactions involved in a savings account, the transactions being designated on tabulating cards which represent old balances, the savings account number, and other information which is to be recorded on a pass book. The pass book is provided with a series of lines to receive data to be recorded. Obviously for each transaction a successive line is to be selected and the present invention provides means which are controlled by the line selecting designations of the transaction card to select such lines to receive the recorded data.

Another object of the present invention is to provide means for comparing the account number data on the transaction card with the account number data on the pass book and to prevent upon a lack of identity the selection of the printing line by the transaction card thereby indicating that either the transaction card or pass book is in error and preventing improper entries.

One construction which fulfills the above object consists, in the present machine, of concurrently analyzing the account number data on the transaction card and then successively comparing the account number data in corresponding columns of the, transaction card and the pass book. A suitable electrical contact making switch rendered effective by the movement of the pass book carriage causes a set of relays for each corresponding column of the pass book carriage and transaction card to be energized or remain deenergized in accordance with the comparison.

These relays cause the operation of suitable control means for the machine to determine whether a printing line is to be selected or not.

A still further object of the invention is to provide a manually settable means for setting up the amount of the withdrawal or deposit and which means controls a printing mechanism so that this data is printed on the pass book and upon a line thereof determined by the line selection designation of the transaction card. If

so desired, as shown herein, the account number data is also printed on the pass book, as well as the date of the transaction which is set up in the machine.

As previously intimated each transaction card is perforated in a single column so that this perforation may control the differential displacement of the pass book carriage. A further object of the invention consists in the provision of means for interpreting this data and to con-. trol means to cause the punching machine to punch the next transaction card with line selection data so that the next line on the related pass book will be selected for printing operations.

A still further object consists in the design of means which represents a simplification of means previously devised to secure certain of the results attained herein, being particularly concerned with the account number comparing means; the means for selecting printing lines of the pass book under control of the line selection designations of the transaction cards, the means for causing the account number data comparing means to determine the utilization of the aforesaid line selecting means and the provision of means whereby a well known form of punching machine may be utilized in connection with the improved machine with very little modifica-- tion so as to provide the perforation of a successive transaction card with a designation for selecting the next line of the related pass book.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawings whether within orwithout the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

Fig. -18 is a sectional view of another onerevolution clutch mechanism and is taken on the line iii-l8 of Fig. 6.

As previously explained the improved machine is adapted to be utilized for accounting of deposits and withdrawals made in a bank. In order 5 to better understand the operation of the machine its operation will be given in an orderly manner commencing with the preparation of. a balance card and pass book for an initial account and then for subsequent deposits and withdrawals 40 which make up the subsequent transactions at the bank in which the account is placed.

Figure 2 is a showing of a tabulating card of a well known form and is of the type shown in the patent to C. D. Lake, No. 1,772,492, dated August 12, 1930. The tabulating card contains perforations in vertical columns which are adapted to represent digital values and also alphabetical characters for alphabet data. Each tabulating card, representing an initial transaction for a 0 new account as card "I in Fig. 2 or for a subsequent transaction as by card IN in Fig. 3, is divided into fields which in succession from left to right represent the account number, the name of the depositor, the address thereof and the date.

The remainding card fields include a single column in which is located one or more perforations to select the line for which recording is effected on the pass book. The next card field is perforated to represent the old balance and which in the initial deposit is perforated to represent aero.

The next card field comprises a single column designating the type of transaction. namely, a withdrawal or deposit. One of the two card fields at the extreme right are allocated for the designation of the amount of the transaction whether it is a withdrawal or deposit and the other for the amount of the new balance.

The blank card which is to indicate the opening of an account isplaced in a well known form of key controlled punching machine (Figs. 15

and 16) so that-the data pertaining to the opening of an account will be punched thereon. The form of punching mechanism preferably employed in connection with the present system will be subsequently described in detail.

By the depression of the. appropriate keys 9 (Figs. 15 and 16) the tabulating card placed in such punching mechanism will be punched to represent the account number and such numbers are obviously selected according to a serial order. 5 Thereafter, the next card field is punched to represent the name of the depositor and in the next card field the address of such depositor. The card is also punched to represent the date of the opening of the account and the column for line 10 selection is punched to represent 1", as shown in; Fig. 2, to thereby cause the initial recording on the pass book on-the first line by means to be subsequently explained in detail. As previously stated, the field for the old balance is punched to 15 represent zero.

' The pass book ii comprises a card folded in the center as illustrated in Fig. 7 by a dotted line and as shown therein the name of the depositor and the account number allocated to such depositor 20 is written on the top. The pass book is opened as shown in Fig. 7 and is inserted in the key controlled punching machine so that the lower part thereof is punched to represent the account number which is allocated to the depositor and in all 25 transactions should conform to the account number punched upon the new and with each of the successively selected old balance cards "H which are picked from the files as successive transactions are made for the depositor's account. so The above is a description'of the preparation of the initial balance card and the pass book for opening of an account. Thereafter, as will now be described, the balance card'is placed in the machine shown herein and the pass book is placed 35 on a carriage therein so that by the manual movement of the carriage the latter will be moved to cause a card sensing operation so that the account number punched on the pass book may be automatically compared column by column .40 with the account number punched on the balance card. Since in the initial opening of an account there is little opportunity for lack of identity between 9. pass book and the balance card, such a comparing operation for the initial account is not 45 essential but as hereinafter described such identity for subsequent transactions must be preserved between the pass book and the old balance transaction card and both should pertain to the same account. 50

Card analyzing mechanism When the tabulating card I has been punched to designate data for the opening of a new account, the latter is inserted in the machine, as 55 shown in Fig. 6, in order that the account number may be-- analyzed by analyzing mechanism now to be generally described. The analyzing mechanism for analyzing the card 10 is preferably of the type shown in and claimed in the ap- 60 piication to T. E. Torkelson. Serial No. 117,282, filed December 28, 1936 and will only be generally explained herein and in connection with Figs. 6 and 13. v v

The assembly plate for the analyzing mechanism comprises a back plate l2 and a pair of integral side plates l3 and H which are provided with slots engaging guide pins ii carried by the side frames of the machine whereby the movement of the analyzing frame is guided. Carried 70 by the back plate i2 is an analyzing head which carries columns of spring contact elements ii. there being a vertical column of contacts It for each of the columns of the card to thereby analyze the perforations'therein. Each column 7 of contact elements l6, has an electrical contact with a common conducting bar I1 and each contact I6 is adapted to pass through a perforation in the column and contact with a related contact point l8. There is, of course, one contact point l3 for each contact element l6 and groups of the latter are embedded in a fixed insulating member I9. The analyzing mechanism is shown in shifted or analyzing position in Fig. 6 and obviously in the normal position there is a space between the contact elements l6 and .the contact points l8 so that the card It) may be freely inserted therebetween until the lower edge of the card I rests upon a pair of card stops 20.

Connected at their ends by a pin 2| (Fig. 6) is a pair of toggle levers 22 and 23, the toggle lever 22 being connected at 24 to the analyzing frame and the toggle lever 23 is pivoted upon a fixed rod 25. extension 26 which is connected by a pin 21 to the core 28 of an analyzing control magnet 29. When the magnet 29 is energized, the core 28 will be atttracted downwardly to the position shown in Fig. 6 thereby rocking integral extension 26 of the toggle lever 23 clockwise until the point of the toggle levers 22 and 23 as the pin 2| moves upwardly past the center of the toggle system and until the toggle lever 23 abuts an adjusting screw carried by the stationary rod 30. This position of the toggle levers 22-and 23 will be maintained by a spring 3| connected to the lever 26 so as to retain the analyzing head in analyzing position. The means for causing the movement of the analyzing head to analyzing position is under control of an operating key 32 shown in the Wiring diagram in Fig. 1b. This key is operable exterior of the machine and when depressed closes contacts 33 thereby closing the circuit to .the magnet 29 through relay contacts 10a now closed and across a positive bus bar 34 and a negative bus bar 35. As previously, the energization of the magnet 29 causes the movement of the analyzing head and the contact points I6, associated with the columns in the card l0 which are perforated to represent the account, will pass through such perforations and make contact with the appropriate contact points I8 to thereby continue the closure of comparing circuits to be subsequently described.

Pass book carriage The pass book carriage is shown in Figs. 6, 10, and 11 and as shown therein comprises a pass book supporting plate 36 which carries lateral guide plates 31 and 38 slidable in longitudinal slots 39 (Fig. 10) formed in side frames 40, 4|. By such guiding means, the carriage may be moved within the machine. The pass book II is inserted in an aperture 42 (Fig. 11) formed by a pair of spaced stationary guide plates 43, 44'and the card is manually pushed on the card carriage to occupy the position shown in Fig. 11.

The pass book carriage is also provided with an analyzing mechanism for the four columns of account number data and is generally designated by 45 and is of substantiallyv the same construction as that described in connection with the card analyzing mechanism and is so moimted upon the end of the pass book carriage as to be correlated with the four columns of the pass book which are punched to represent the account number. As best shown in Fig. 11, the pass book analyzing mechanism comprises four columns of contacts 46 contacting with four contact bars 41 each common to a column of con- Toggle lever 23 has an integral 48a attached to the pass book carriage and this overhanging portion is adapted to firmly hold the pass book upon the carriage. The spring contact elements 46 will, in the manner previously described, pass through the perforations and make contact/with the correlated contact bar 48.

When the pass book is placed upon the carriage, by means of a finger piece 49 secured to the carriage the carriage may be moved to the left as shown in Fig. 10. Dependently carried by the pass book carriage is a plate 50 (see Fig. 6) which carries a series of insulated contact elements 5|, 52, and 53 (see also the wiring diagram, Fig. 11)).

Referring now to the wiring diagram (Figs. 1a. and 1b) it will be seen that when the carriage 56 is manually moved to the left as shown in Fig. the contact element 53 will successively contact four stationary contact elements 54 and thereby extend a circuit from the positive line side 34 (Fig. 1a) through a wire 55, relay contacts 56a, wire 51 (Fig. 1b) which is connected to the contact element 53. From the four contact elements 54 there are wire connections 58 which lead as shown in Fig. in to the common conducting bars 41 of the pass book analyzing mechanism. The circuits also extend from the bars 41 by wires 59 and normally closed relay contacts l60a to the common conducting bars H of the card analyzing mechanism.

It will be observed that when the account number perforation in the first column of the pass book is analyzed the circuit will lead from the positive line side 34, wire 55, relay contacts 56a, wire 51, contact 53, the first column contact 54, wire 58, common bar 41 for the first column, the contact element 46 passing through the 'perforations at the 2 position, the contact bar 46, and a wire to a relay magnet 6| and to the nega-' tive line side 35. The circuit will also be extended from the'bar 41 for the first column by the wire 59, relay contacts I60d, common bar I1, the contact spring element l6 of the card analyzing mechanism which passes through the perforation at the 2" position, contact point I8, and thence by a wire 62 through normally closed relay contacts IBM. and to a relay-magnet 64, to the negative line side 35. If there is an identity in account number perforations on the pass book and card, related magnets 6| and 64 will be simultaneously energized so that the relay magnet 6| will open relay contacts 6|a. Relay magnet 64 when energized will open its relay contacts 64a.

It will be seen, therefore, by the alternate position of the armatures of the corresponding relay magnets 6| and 64 that a circuit describedas follows will be open: from the negative line side 35, through a wire 65, a wire 66, relay contacts 6|?) now'closed, a wire 61 to the relay contacts 640., which are now open, a wire 8| to a relay magnet 56, and to the positive line side by wire taneously energized. As the carriage is manually moved, the contact element 53 will engage the successive contact elements 54 thereby eflecting a comparison between the perforations of corresponding columns of the pass book and the tabulating card.

In the event that there is a proper identity in the account number analyzed on both the card and the pass book the following circuit will be made. From the positive line side 34, wire 55, relay contacts 55a, wire 51, movable contact element 53, a stationary contact element 68, to a wire 68, a punch control magnet 1|, 9. wire 12,

wires 13 and 14 to contacts 15. As best shown in Figs. lb and 10, the card carriage has attached thereto a ratchet toothed plate 16 carrying a roller 11 which in the initially moved position of the pass book carriage permits contacts 15 to close thereby extending the circuit through the contacts 15 to a wire 18 thence to contacts 18 and. a wire 82 to the negative line side. As will be subsequently explained, the energization of the punch control magnet 1| will cause automatic punching operations to be effected by a punching machine.

In the event that one of the perforations of the corresponding columns of the card and pass book disagree it will be seen that the normal closed position of relay contacts 8la or 84a for non-corresponding relay magnets BI and 84 will be retained due to the fact that corresponding relay magnets 8| and 84 are not energized,

\ thereby closing the circuit across the wires 88 and 8| by either a wire 61 or a wire 88 to cause the relay magnet 56 to be energized and open its relay contacts 55a and close its relay stick contacts 56b. The closure of the latter will extend the circuits from relay magnet 56 to a wire finally makes contact with the contact point 88,

the above described circuit for the punch control magnet II will not be closed due to the previous opening of the contacts 58a. This willprevent the energization of the punch controlmagnet and punching operations will not be instituted and which absence of operation will be recognized -.by the operator thereby indicating to the operatorthat the account numbers punched on the card and the pass book are in disagreement.

Means for determining the position of pass book carriage for. selection of line printing From Fig. 7 it will be observed that the pass the selection of the first printing line on the pass book. This is effected by means now to be de have related wire connections 81 to the ten sta-' ration in the line selecting column. Therefore,

through the movable contact elernent l6 passing through the perforation at the 1 position and contacting with the contact point I8 a circult will be closed when the movable contact element strikes the contact element 881 which has a wire connection to the contact element 8 correlated with the 1" index point position of the line selecting column. This will cause an energization of the carriage stop solenoid 88 by a circuit now to be described. This circuit extends from the positive line side 34 (Fig. 1a), wire 55, relay contacts 55a which are closed if there is an agreement in the account numbers of the pass book and tabulating card, wire 51 to the contact element 53 (Fig. 1b), common conducting strip 85, a wire 89 to the common bar H, the contact points l6 and I8 contacting through the perforation at the 1 index point position, the wire 811, contactpoint 861, contact element 5|, relay contacts |32e now closed, wire 9|, to the solenoid 88, and from the solenoid to the wire 13, the wire 14, contacts now closed, wire 18, contacts 18, and a wire 82 to the negative line side 35. V

Since it is assumed that the 1 index point position is perforated in the line selecting column of the tabulating card the pass book carriage will be stopped at a predetermined position which is selected by the energization of the magnet 88. As best shown in Figs. 1b and 10, the energization. of the magnet 88 will draw within its core 92 and rock a T-shaped member 93 so as to cause a double pawl 84 having a spring connection therewith to engage upper and lower ratchet teeth 85 of the plate 16. The upper and lower ratchet teeth are oppositely, formed so that in coaction with the double pawl they will prevent further movement of the pass book carriage to the left or its restoration to the right.

The carriage is now held in such a position that the subsequent recording operation onthe pass book will be. effected on the first line of the pass book as will be later explained.

It will also be clear that if the account numbers are not in agreement contacts a will be opened and the circuit to the solenoid 88 will not be completed permitting the pass book carriage to be moved entirely within the machine and then restored by a return spring. The failure to stop the carriage during its movement and its full restoration will also be an indication to the operator that the account numbers on-the tabulating card and pass book are in disagreement.

Punching machine The punching machine shown herein in Figs. 15 and 16 is of a type well known in the art and is fully shown and described in the patent to F. Lee'et al No. 1,976,618, dated October 9, 1934. Only so much as is necessary to understand its coordination with the present improvements will be explained.

From Figs. 15 and 16 it will be seen that the punching machine is provided with keys 9 corresponding to those of the patent for manual punching operations to punch the initial tabulating card l for opening an account.

One of the functions of the punching machine is to automatically reproduce on a blank card.v

in the machine the data on 67 columns of the tabulating card I0 (Fig. 2) to thereby produce a duplicate card shown in Fig. 3. This card I 0! comprises the first balance card if a deposit is made.

It will be recalled from Fig. ID that the punching machine control magnet 'II is energized to initiate punching operations so as to cause the closure of relay contacts Ila (Fig. 1e). At the same time relay magnet I60 (Fig. 1b). which is in parallel with relay magnet II, will through its relay contacts I800 also be energized to thereby close its stick relay contacts 5011, providing a stick circuit for relay magnet I60 from the positive line side 34, relay contacts I60d, relay magnet I50, wires 12, I3 and I4, contacts 15 now closed, wire 78, contacts 19, wire 82 to the negative line side 35.

Relay contacts I60a (Fig. 1a) are now opened so these relay contacts I60a disconnect the part of the card analyzer shown in Fig. 1a from the wires 58, and from the magnets 64 to prevent any false circuits possible.

The punching control magnets 50 (see Fig. 1e)

correspond to those in the aforementioned patent and are successively selected as the perforations in the tabulating card I0 in the columns representing the account number are analyzed.

It will be seen that the negative line side 35 is connected to a common side of the punch control magnets 60 by a wire I02 through a relay magnet I03 to be subsequently referred to.

From the magnets 60 there are twelve wire connections I04 connected to twelve corresponding digit selecting wires I060 I069-I06x and l06n, through normally closed relay contacts I631. The wires I06 terminate as shown in Fig. 1e with connections to the wires I04 through the'relay contacts I631 which are now closed. The digits 0-9 aside of a contact point or any line indicates its digital representation while X and R signify punching at the 11th and 12th positions of the tabulating card, respectively. Obviously, for each analyzer section the contact element I8 which engages the related contact element I6 through the perforation in that column will select the appropriate punch control magnet 60. From the four common bars I! of the account number card analyzer (Fig. 1a) there are connections to four wires in a cable I01 which are connected to contact points I08 (Fig. 1e) carried by a stationary strip of a column selector. With these contact points I08 a column selector contact element I09 carried by the card carrying carriage will make successive contact therewith and also with a common conducting strip IIO. From the strip IIO the circuit to the positive line side to energize a selected punch control magnet 80 is through a wire connection III, to contacts I28 now closed, relay contacts Ila now closed, contacts 81 now closed, and a wire II2 to the positive line side 34.

It is explained that due to the previous positioning of a card IM to the punches (Fig. 15) the carriage has skipped under control of a column skip bar (identified in Fig. 15 as "column skip bar" and corresponding to the bar I 52 in the patent No. 1,976,618) to the first column punching position at which time contacts I35 (Fig. 16) (which are the same as in the patent) are o ened through a high part of the skip bar. The column selector I08 is now positioned over the first column contact of the strip so that when relay contacts Ila are closed punching for the first column is effected and automatically continued because the low part of the skip bar will permit contacts I35v to be retained closed.

The column selector shown at the bottom of Fig. 1e, comprising in part elements I 08 and I09, is well known in the art and is fully described in the patent to G. F. Daly et al., No. 2,016,706, dated October 8, 1935.

The means for causing the operation of the punches 5 (Fig. 15) under control of the punch magnets 60 is also well known and is fully described in the patent to Lee et al., No. 1,976,618.

After punching the first balance card IOI with the account number analyzed on the card I 0, successive punching operations occur to punch the alphabet data in columns 5-55 of the tabulating card I0 from the alphabet data analyzer shown in part in Fig. 10.

To this end there are suitable cable connections to the column selector from the common bars II.

of the alphabet data analyzer and in this instance the bars I1 are split so that the index points I-9, inclusive, are related to the lower part of the bar I1 and index points X, R, 0 are related to the upper part of the same bar I1. This is necessary in view of the punching of the perforations in code to represent alphabet data. The twelve wires I05o-I069, I06x, I 06a are also multiplied to the sets of contacts I8 for the selection of magnets 60. Cables H3, 4 (Fig. 10) from the alphabet analyzer are connected to lower contact points on the column selector as shown in Fig. 1e. The cables H5 and H8 (Fig. 1e) from the upper contact points I 08 of the column selector are connected to the upper parts of the bars H, as shown in Fig. 10. Punch ing operations will thus continue automatically and where necessary two punch control magnets 60 are energized for code punching ,in a single column.

The next punching operation comprises punching in columns 5659 of the date on which the transaction occurred and the date setting mechanism is shown in Figs. 8 and 11 and in the wiring diagram in Fig. 10.

Columns 58 and 51 are appropriated for-the punching of a number indicating the twelve months and columns 58 and 59 for the date of such month.

The ten digit selecting wires I06o-l069 leading from the ten control magnets 50 are connected to ten wires II'I (Fig. 1c) and the latter are individually connected to ten commutator segments I I8 formed in an arcuate insulating ring II9 (see I Fig. 11).

Date setting wheels I20 settable exteriorly of p the cabinet carry brushes I22 adapted to contact with the segments H8. The two date setting Wheels I20D at the right (Fig. 8) are set to represent any date from 1-31 and coact with the ten position and under control of this perforationpoint positions. .At the tenth month position of the wheel I 20M the brush I22a coacts with the 0" segment H8 and a brush I22b of the other wheel I20M coacts with a segment I23 which has a wire connection I24 to cause the selection of the l punch control magnet 80. At, the eleventh month position both brushes I22a and I22b contact the segment I23, and at the twelve month position the brush I 22b contacts with the segment I23 and brush I22a contacts with a segment I25 having a. wire connection I26 to select the "2 punch control magnet. I

Against each ring I21 (Fig. 11) carrying a brush I22 bears a contact plate I 3| and the four contact plates I.3I have wire connections to wires in a cable I30 through normally closed relay contacts I63d. The cable I'30connects as shown in Fig. 1e to contact points of the columnselector' for columns 56-49. I

The next automatic punching operation is to punch a perforation in column 60 to represent the next line to be selected on the pass book for recording. This is necessary because the first balance card will be used in the subsequent transaction just as the initial tabulating card was, and therefore, the next or second printing line of the pass book must be selected. .In the initial account the perforation was at the 1 index point the first balance-card 'IOI will be punched at the "2 index point position (see Fig. 3) by means now to be described.

When the pass book carriage is moved to a line selecting position a. selected one'of aseries of relays I32 (Fig. 1c) is set up under control of the analyzer for the line selecting column. In the example assumed, for the "1 index point perforation a circuit described as follows will be completed to a relay magnet I32: (Fig. 10). From the positive line side 34 (Fig; la) wire 55, relay contacts 56a, wire 51 (Fig. 1b) contact element 53,contact strip 85, wire 89, common bar I'I, contacts I8 and I8 engaging through the perforation at the "1 index point position, wire 811, to relay magnet I321 (Fig. lc) through its relay contacts I32b, and by a common'wire I33 for I said magnets I32 to a wire I3 which leads to the negative line side 35 as previously described. The relay magnet I321 will close its relay contacts I32a to provide a stick circuit by a wire I34 to the positive line side 34. Relay contacts I320 will also close and by a wire connection I362 'connected to the desired wire I 062 a punch control magnet 60 wilLbe selected for energization which will cause punching of the next higher index point position, or at the 2", index point position in the example. assumed. Therefore, if an old balance card is punched from either I to 8, the next higher index point position, or 29, will be punched on the next balance card, effected by the appropriate wire connection between the wires I08 and the wires I36.

To complete the circuit to the selected punch magnet a common conducting wire I31 for the relay contacts I320 (Fig. 1c) is connected as shown in Fig. 1e to the lower contact point for the column selector at the 60th column.

Later there will be described the means for changing the punching from "9, -to represent "10 at the line selecting column on the next balance card, etc.

Thereafter under control of the card analyzer for columnsBI-GG the punching operations continue to represent by perforations on the new balance c rd th old balance on the previous balance card and which for an initial account is 000000. In view of the fact that such punching involves mechanism to be later described the specific manner in which this is accomplished will be later described. At the 67th card column position the high part of the skip bar opens con- Setting up amounts for withdrawal or deposit The amount which is deposited or withdrawn is set up in the machine after the punching machine has duplicated data and punched other data to represent a new balance card. When the punching operation is terminated either a Deposit key I38 (Fig. lb) or a Withdrawal key I39 is depressed: depending on the transaction.

If key I 39 was previously depressed a circuit toa magnet I40 is closed and held closed by the following described circuit: from the negative line side 35, wire 82, wire I M, contacts I42 closed by key I39, relay contacts I40a, relay magnet I40; to wire 51 which leads as previously described to the positive line side 34. Relay contacts I40b are stick. circuit contacts closing a stick circuit through contacts I43 opened by the key I38. Due to the previous locked up circuit of the relay magnet I40 it is necessary to depress the Deposit key I38 to open the stick circuit by opening of contacts I 43. Since for the example assumed the initial amount is a deposit of $50.00 the Deposit key I38 is depressed.

From Fig. 1b it will be seen that the Deposit key I38 is adapted. to close contacts 3I I and that the Withdrawal key I 38 is adapted to close contacts 3" both of which extend the circuit from the negative line side 35 to wire 82, wire I through either contacts 3) or 3 through relay contacts 3I2a to a relay magnet 3I2, thence to wire 51, and through relay contacts 56a (Fig. 1a) wire 55 to the positive line side 34. A stick circuitto the negative line side 35- is effected by stick relay contacts 3I2b,- relay contacts IIb now closed, and wires MI, and 82.

Withdrawal or amount setting means The amount setting means for entering the withdrawal or deposit amounts in the machine comprises a series of six slides I44 which as shown in Figs. 11 and- 14 are manually settable exteriorly of the machine. Each slide I44 at the left side thereof carries a single contact element I45 (Fig. 12) which is positioned for cooperation with one of a series of ten contact points I46 dependent upon the digit positioning of the slide I44. Each slide I44 is manually drawn towards the operator against the action of a spring I41 and the difl'erential position of the slide is maintained by a retrograde preventing pawl I48 (Fig. 11) engaging a ratchet tooth I48 of the settable slide I44. If an errorhas been made in setting the slide, a projecting portion I50 of the retrograde preventing pawl I48 is manually moved to disengage the pawl from the I amounts have been set up as just described the operating key 32 (Fig. 1b) is again depressed which will close the circuit from the positiveline side 34 through relay contacts 10a now closed, contacts 33 closed by the operating key 32, and thence by a wire II to the punching machine control magnet II and the circuit then extends by the wire I2, 13, I4, contacts 15 and I9 and wire 82 to the negative line side 35. As previously stated, the energization of the relay magnet II will close its relay contacts 'IIa shown in Fig. 1e to thereby cause as previously stated the automatic operation of the punching machine so as to now punch on the new balance card certain data in columns 61 to 19.

Operation of punching machineContinned When the operation of the punching machine is resumed the indication of the type of transaction is punched upon the new balance card in column 61 and by the following described means and such means is operative only if the amount entered is a withdrawal.

Since in the example assumed the first transaction is a deposit no punching will be effected in column Gland since no punching control magnet 60 will be energized, it is, of course, necessary to provide additional mechanism so as to cause the automatic spacing of the carriage to the next column punching position. This arrangement is also effective in alphabet punching where certain columns are not punched. Such an arrangement is well known to those skilled in the art and is fully shown and described in the patent to W. F. Gutgesell, No. 1,939,049-and for this reason is only generally described herein.

In this instance, the following described circuit will be closed, from the positive line side 34 (Fig. 1e), wire II2, contacts 81 now closed, relay contacts I la now closed, contacts I28 now closed, wire I52 to a relay magnet I53 and thence to relay contacts I03a which are now closed because relay magnet I03 which is in series circuit with the punch control magnet circuits is not energized and thence by a wire I54 to the negative line side 35. The energization of the relay magnet -..53 will cause the closure of relay contacts I53a thereby causing the punch magnet I55 to be connected across the positive and negative line sides and therefore energize in the same manner as it is energized by the circuit connections described in the aforementioned patent to F. Lee et al., No. 1,976,618. It is pointed out that the punch magnet designated by reference numeral I55 herein corresponds to the punching magnet in the last mentioned patent and designated therein by reference numeral 49.

By the above described mechanism, the carriage will be moved to the extent of a single column so that the amount of the transaction may next be automatically punched in columns 58 to 13 by the following described mechanism.

There is shown diagrammatically in Fig. 1d the electrical connections for causing the selection of the punch control magnets 60 under control of the amount setting slides I44 but only for three orders thereof in view of the duplicate arrangement for the six denominational orders. Taking into consideration the hundreds of thousands order, which is the first order to be punched, it will be seen that connected to the ten wires I0Iio-I069 which are connected to the punch control magnets 60 for punching at the index point positions zero to nine inclusive, there is a cable connection to such wires and such cable is designated by reference numeral I56 (see Fig. 1d). These ten Wires I51 in the cable I56 as shown in Fig. 1d are connected to the series of ten stationary contact points I46. The movable contact point I45 correlated therewith has a wire connection I58 to a wire I59 through closed relay contacts I63h. The wire I59 leads as shown in Fig. 1e to a contact point of the column selector appropriated for the 68th column position and the particular control magnet 60 which will be selected for energization will of course be dependent upon the differential position of the slide I44 and the corresponding correlation of the movable contact point I45 with one of the stationary contact points I46. Thereafter, the carriage is stepped step by step and the digit amounts set under control of the remaining slides I44 are read out by the column selector as the carriage moves step by step.

At the termination of such card punching operations columns 68 to I3 will be punched to represent the amount of the transaction and in the example assumed only the slide I44 of the tens of dollars order will cause punching of 5 and the number punched will be indicated as $50.00.

Means for punching the new balance card to indicate a withdrawal if the transaction should be a withdrawal It will be observed from Fig. 1b that in such instance the withdrawal key I39 is pressed to cause energization of the relay magnet I40 which upon its energization causes the closure of contacts I400. From the column selector contact for the 67th position, there is a wire connection I62 (see Fig. 1e) which is connected as shown in Fig. 1b to normally closed relay contacts I63a. From the relay contacts I 63a there is a wire connection to the relay contacts M00 and from the last mentioned contacts there is a wire connection I64 to a wire 406x which leads to the punching control magnet 60 for causing the punching at the X index point position. Therefore, if the entry should be a withdrawal the card will be punched in the 67th column to indicate this fact on the new balance card.

Punching of new balance After columns 68-13 have been punched to represent the deposit or withdrawal amount there is a selection of punch control magnets 60 to automatically punch the new balance and is dependent upon the old balance punched on the card analyzed and the setting of the control slides I44 to represent the deposit or withdrawal. This joint cooperation involves a number of circuits not shown herein as it forms no part of the present invention and is fully disclosed in the parent application. The punching of a new balance is shown in Fig. 3 in columns 14-19 and thereafter the punch carriage skips to column 80.

In the present example there is no punching in the 80th column and the carriage is automatically escaped to this column and thereafter, by carriage controlled means fully shown in the patent to Lee et al., No. 1,976,618, contacts I9I in Fig. 1e will be closed. This will cause the energization of the relay I91 and the closure of its relay contacts I98 and the energization of the ejection magnet I99. This causes the operation of the ejector 201 (Fig. to eject the punched
