- This invention relates to punching machines and more particularly to the type which is adapted for punching tabulating cards which are "subsequently used in accounting and billing operations.
- the principal object of the present invention is to provide a punching machine with keyboard verifying and card checking arrangements which will not only verify the .accuracy of the previous keyboard operations by the operator but will also check the punching effected by the punching machine to determine wh'ether the data punched on the card corresponds to the verified digital setup.
- a still further object of the machine closely allied to the principal object of the invention is to provide such arrangements with a mode of operation which will enable the keyboard controlled verifying operations and digital punching verifying operations to be effected in an overlapping sequential operation Without holding up the operator so that it is only necessary for the latter to operate the keyboard to set up the data relating to the original record and to repeat the keyboard operations for verifying purposes.
- One object of the present invention is to provide a digit storage arrangement which consists principally of banks of storage relays which are.
- a further object of the invention is to provide an error correcting mechanism which will enable the release of the digital setup of the storand correspond with the original data set up.
- a further object of the invention consists of a selective arrangement which enables the storage vcolumns in which the error has been located to be released without, however, effecting the digital setup of the storage columns pertaining to the preceding columns which have been determined to' be correct by the verification of such columns.
- a still further object ofthe invention is the provision of a digit storage arrangement which enables the representation of the digits according to a code so that While the digits 0 to 9 may be punched on the card, a lesser number of relays may be utilized to set up such digital representations and a still further object of the invention in this connection is to provide a translator wh'ich will convert the combinational digit representation on the storage columns to the original digit representations -9 for the operation of corresponding punches in the punching machine.
- the digit storage columns control a card punching machine of the successively actuated type and While the construction of the machine may be such that card umns has been verified the punch operates immediately to punch the card under their control.
- a relatively important object of the invention is to providev a comparison of the card perforations with such storage columns and to provide the desirable overlap between card punching operations and checking operations for the previously punched columns.
- the original digit setup of the verified storage columns is retained and when the card previously perforated voccupies a position in the punch' whereby its perforations may be analyzed, a comparing mechanismv is initiated which will comparer the card Vperforation with the vdigit setup of the related storage column.
- a still further object of the invention is to convert the digit representation of the card perforations according to the Hollerith system to a digit representation effected .by the combinational code and which code corresponds to the code used for the digitrepresentaton of the storage columns.
- the checking of the card punched according to the Hollerith system may be compared with the combinational digit setup of the controlling storage columns but if so desired the combinational setup of the storage columns may be converted to the digital representation according to the Hollerith system to obtain a direct comparison therewith.
- a further object of the invention relates particularly to increasing the eiliciency of machine operations and the desirable overlap between the punching operations and the card checking operations which will ⁇ enable the latter to be initiated .beforepunching operations are completed.
- the card checking operations are initiated after seven columns of the card have been punched but this is d ue to the relative column displacement of the card punches and analyzing brushes for the checking mechanism and by bringing such elements closer together, it .will be seen that checking operations may be effected almost directly after the card column has been punched. However, the mode of operation in the present machine indicates that such overlapping operations ensue with an increase in the eiilciency of machine operations.
- Another object of the present invention is to release those storage columns which have been compared with the card perforations where indication of accuracy exists and the release of such storage columns will enable the operator to again set up the cleared-out storage columns to represent the digits of the next record.
- the sequence of operations of the verifying, card punching and check arrangements is such that in one point of the operation of the machine different operations may be effected. First, the verification of certain of the storage columns;
- the machine includes further a series of signal lights which indicate the progress of the operatorin the successive digit setup of the storage columns; either for the original digit set up or for the verication of the previous digit set up. It is preferable to provide a plurality of these signal lights; one signal light for each card field which consists of a plurality of card columns which receive the digit representation of related data.
- a still further object of the invention in connection with the provision of signal lights is the incorporation of another signal light which will indicate visibly that the'verifying of digit set up for any storage column has indicated a variance with the previous digit set up, and to make more clear this indication a single buzzer is also provided to audibly indicate the existence of an error. Preferably repetition of key strokes in an attempt to further verify successive storage columns will repeat this audible indication.
- a visible signal is also provided to indicate when a continues with card checking operations of the machine in connect-ion with the same card, the failure to eject thecard which has been found to be perforated in error will be a further indication to the operator of the discrepancy, so that the incorrect card -may be removed and keyboard operations can be repeated to produce a card which corresponds to theoriginal data to be punched.
- Fig. 2 outlines the manner in which the sheets of the wiring diagram should be assembled.
- Fig. 3 is a representation of part of a card perforated by the punching machine.
- Fig. 4 is a central longitudinal sectional view of the preferred form of'punching machine used machine.
- Fig. 6 is a sectional view of the keyboard.v
- the present arrangement consists of a keyboard, a relay storage unit and a punching machine, or card punch.
- the arrangement provides for punching a certain-number of card columns with keyboard verifying and digital punching checking operations to insure accuracy in card punching.
- a single storage unit is provided 'and to prevent' .any delay to the operator bypunching operations from the storage unit it is desirable to provide an overlapped sequence of operating punch and storage units.
- the operator first operates the keyboard to set up the desired data in the storage units. After the data has been set up, a second operation of the keyboard follows to verify the data set up in the storage units. If certain data previously set up is lincorrect ⁇ when the repeat keyboard operation varies from the first keyboard operation, a warning signal is given and by the provision of selective instrumentalities only a section of the storage units containing the erroneousv setup need be wiped out, leaving intact the setup of the correct information. If
- all the storage units can be' cleared of their 4data set up or, by the selective instrumentalities, certain sections of the data storage units may be cleared out upon an indication of an error.
- Another novel feature of the invention is the possibility of causing punching operations to be eiected under control of those storage units which have been found to be correct in their data set up.
- This ,overlap principle of operation enables the operator to verify the setting of storage units while the punch is operated to 'punch a card to represent the data set up on storage units previously verified and found to be correct.
- the machine can be arranged so that ,it is possible to have the operator verify information on a storage unit while the punch is punching a column only one or two columns behind the operator.
- Simplification of the circuit is enabled by dividing the storage units in sub-l divisions generally corresponding to card ileld or parts of card relds so that the punch will not ⁇ begin punching a card field until the operator has completely verified that 'subdivision of the storage units.
- the sub-divisions which are made for punching a card will be explained later.
- VAA cated seven spaces or columns distant from the punches so that seven spaces after a column of a card has been punched the punched card column is read by the checking or analyzing station.
- checking circuit isl provided so that if the hole y or holes analyzed do not agree with the setup of the storage unit for that column from which that card column was punched,l an error indication is made and while further card checking operations may ensue card ejecting operations of the punch are suspended. After the punch has punched and checked oneA of the storage unit sub-divisions, that subdivision may be cleared in Thus. if the punch has been lagging behind .the operator so that the operator is prepared tobegin the setup of a new card before the punch has completed punching the previous card, it is possible for the operator to proceedA with the setup to a. point as far as the punch has completedthe check Without waiting for the punch to Acompletely punch the card.

Business Machines 46 Claims.
This invention relates to punching machines and more particularly to the type which is adapted for punching tabulating cards which are "subsequently used in accounting and billing operations. Y
The principal object of the present invention is to provide a punching machine with keyboard verifying and card checking arrangements which will not only verify the .accuracy of the previous keyboard operations by the operator but will also check the punching effected by the punching machine to determine wh'ether the data punched on the card corresponds to the verified digital setup.
A still further object of the machine closely allied to the principal object of the invention is to provide such arrangements with a mode of operation which will enable the keyboard controlled verifying operations and digital punching verifying operations to be effected in an overlapping sequential operation Without holding up the operator so that it is only necessary for the latter to operate the keyboard to set up the data relating to the original record and to repeat the keyboard operations for verifying purposes. It has been the previous practice for the verification of card punching operations by repeat Akeyboard operations to provide a separate key controlled verifying machine which will determine the accuracy of the card punching operations but such repeat keyboard verifying machines have, accordingto prior constructions, been constructed as an independent keyboard controlled unit. Hence, for
card punching and verifying operations, two ma- `chines Were necessary; the original key controlled punching machine and the key controlled verifying machine and necessitating two operators to secure the final product. In the key controlled verifying machine the punched card was, however, not analyzed to determine the accuracy of th'e perforations made by the punching machine and in such forms of machines, the
operation of the keyboard of the verifying ma-l chine solely determines whether the same keyboard strokes were performed in the card punching machine. While card punching machines have been ordinarily found to be accurate in their card punching operations, in some jobs it is highly desirable and essential from `an accounting standpoint to insure by the highest percentage of accuracy that the card punching operations are correctly performed by the machine of the key controlled verifying operations and thedigital punchingcard checking operations, the accuracy of the nal product is made more nearly certain; -and further, any deviation in the repeat keyboard operations and card punching from the originalkeyboard operations is indicated to the operator in suitable Ways so that the reason for the error can be ascertained and corrected.
One object of the present invention is to provide a digit storage arrangement which consists principally of banks of storage relays which are.
set up under a control keyboard; and by the key strokes of the keyboard the various storage co1- umns are successively set up to represent the original data. It sometimes happens that the attention of the operator is diverted, or th'at the original data is incorrectly read, which will be reiiected in an incorrect setting of one of the storage columns of` the digit storage arrangement and in order to locate such inaccuracies the present machine includes `an arrangement,
which, by means of repeat keyboard operations, the inaccuracy of the 'original digit set up may be determined. This preferably consists of a supplemental digit setup controlled by the storage relays and as the repeat key operations are effected the digit entered by these keys is compared with the previous digit set up for the related storage columns. Any non-correspondence is indicated to the operator. v
A further object of the invention is to provide an error correcting mechanism which will enable the release of the digital setup of the storand correspond with the original data set up.
necessary that such storage columns be released so that they 4may be reset andv again verified and a further object of the invention consists of a selective arrangement which enables the storage vcolumns in which the error has been located to be released without, however, effecting the digital setup of the storage columns pertaining to the preceding columns which have been determined to' be correct by the verification of such columns. 1
A still further object ofthe invention is the provision of a digit storage arrangement which enables the representation of the digits according to a code so that While the digits 0 to 9 may be punched on the card, a lesser number of relays may be utilized to set up such digital representations and a still further object of the invention in this connection is to provide a translator wh'ich will convert the combinational digit representation on the storage columns to the original digit representations -9 for the operation of corresponding punches in the punching machine.
In the instant device, the digit storage columns control a card punching machine of the successively actuated type and While the construction of the machine may be such that card umns has been verified the punch operates immediately to punch the card under their control.
While the machine described up to this point is completely operative and admirably fulfills most of the requirements for card punching, it is further desirable that the card perforations be checked against the digital representation of the related storage columns.
A relatively important object of the invention is to providev a comparison of the card perforations with such storage columns and to provide the desirable overlap between card punching operations and checking operations for the previously punched columns. To this end, the original digit setup of the verified storage columns is retained and when the card previously perforated voccupies a position in the punch' whereby its perforations may be analyzed, a comparing mechanismv is initiated which will comparer the card Vperforation with the vdigit setup of the related storage column.
- A still further object of the invention is to convert the digit representation of the card perforations according to the Hollerith system to a digit representation effected .by the combinational code and which code corresponds to the code used for the digitrepresentaton of the storage columns. By provision of' such means, the checking of the card punched according to the Hollerith system may be compared with the combinational digit setup of the controlling storage columns but if so desired the combinational setup of the storage columns may be converted to the digital representation according to the Hollerith system to obtain a direct comparison therewith.
A further object of the invention relates particularly to increasing the eiliciency of machine operations and the desirable overlap between the punching operations and the card checking operations which will `enable the latter to be initiated .beforepunching operations are completed. The card checking operations are initiated after seven columns of the card have been punched but this is d ue to the relative column displacement of the card punches and analyzing brushes for the checking mechanism and by bringing such elements closer together, it .will be seen that checking operations may be effected almost directly after the card column has been punched. However, the mode of operation in the present machine indicates that such overlapping operations ensue with an increase in the eiilciency of machine operations.
Another object of the present invention is to release those storage columns which have been compared with the card perforations where indication of accuracy exists and the release of such storage columns will enable the operator to again set up the cleared-out storage columns to represent the digits of the next record. The sequence of operations of the verifying, card punching and check arrangements is such that in one point of the operation of the machine different operations may be effected. First, the verification of certain of the storage columns;
the punching of the card under control of the verified storage columns; and further the checking of the perforated card columns with the related verifled storage columns; and after the verification of one card, three operations may be' comparison with the related verified storage columns; and further the setup by the operator of v the storage columns which have been cleared out and found to be correct in their digit representation by comparison with the related perforated card columns.
As a further object of the invention, the machine includes further a series of signal lights which indicate the progress of the operatorin the successive digit setup of the storage columns; either for the original digit set up or for the verication of the previous digit set up. It is preferable to provide a plurality of these signal lights; one signal light for each card field which consists of a plurality of card columns which receive the digit representation of related data.
A still further object of the invention in connection with the provision of signal lights is the incorporation of another signal light which will indicate visibly that the'verifying of digit set up for any storage column has indicated a variance with the previous digit set up, and to make more clear this indication a single buzzer is also provided to audibly indicate the existence of an error. Preferably repetition of key strokes in an attempt to further verify successive storage columns will repeat this audible indication. A visible signal is also provided to indicate when a continues with card checking operations of the machine in connect-ion with the same card, the failure to eject thecard which has been found to be perforated in error will be a further indication to the operator of the discrepancy, so that the incorrect card -may be removed and keyboard operations can be repeated to produce a card which corresponds to theoriginal data to be punched. y
Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principle of the invention and the best mode, which has been contemplated, of applying that principle.

General description The present arrangement consists of a keyboard, a relay storage unit and a punching machine, or card punch. The arrangement provides for punching a certain-number of card columns with keyboard verifying and digital punching checking operations to insure accuracy in card punching.
A single storage unit is provided 'and to prevent' .any delay to the operator bypunching operations from the storage unit it is desirable to provide an overlapped sequence of operating punch and storage units.
In general the operator first operates the keyboard to set up the desired data in the storage units. After the data has been set up, a second operation of the keyboard follows to verify the data set up in the storage units. If certain data previously set up is lincorrect `when the repeat keyboard operation varies from the first keyboard operation, a warning signal is given and by the provision of selective instrumentalities only a section of the storage units containing the erroneousv setup need be wiped out, leaving intact the setup of the correct information. If
the operator discerns an error in the first keyboard operation, all the storage units can be' cleared of their 4data set up or, by the selective instrumentalities, certain sections of the data storage units may be cleared out upon an indication of an error.
Another novel feature of the invention is the possibility of causing punching operations to be eiected under control of those storage units which have been found to be correct in their data set up. This ,overlap principle of operation enables the operator to verify the setting of storage units while the punch is operated to 'punch a card to represent the data set up on storage units previously verified and found to be correct. If so desired, the machine can be arranged so that ,it is possible to have the operator verify information on a storage unit while the punch is punching a column only one or two columns behind the operator. Simplification of the circuit is enabled by dividing the storage units in sub-l divisions generally corresponding to card ileld or parts of card relds so that the punch will not `begin punching a card field until the operator has completely verified that 'subdivision of the storage units. The sub-divisions which are made for punching a card will be explained later.
As the punch punches the card it is desirable to check the punched information or data against the original setup in the storage units to determine whether correct punching operations have` lpreparation for further setup operations.
cated seven spaces or columns distant from the punches so that seven spaces after a column of a card has been punched the punched card column is read by the checking or analyzing station. VAA
checking circuit isl provided so that if the hole y or holes analyzed do not agree with the setup of the storage unit for that column from which that card column was punched,l an error indication is made and while further card checking operations may ensue card ejecting operations of the punch are suspended. After the punch has punched and checked oneA of the storage unit sub-divisions, that subdivision may be cleared in Thus. if the punch has been lagging behind .the operator so that the operator is prepared tobegin the setup of a new card before the punch has completed punching the previous card, it is possible for the operator to proceedA with the setup to a. point as far as the punch has completedthe check Without waiting for the punch to Acompletely punch the card. In the normal speed attained by the operators in keyboard operations, the above sequence lof events in overlapping relationship will eliminate any delay to the operators so that key operations may continue without interruption in spite of incidental operations effected in the punch such as card feeding and card ejection which are to be performed before al succeeding card is to be punched.
, Keyboard Mounted on thev keyboard (Fig. 6) is a single series-of ten digit keys |00 (Fig. 1b) marked 0-9 as well as an Error key I0| so designated, and a bar |02 known as Manual bar. This bar is depressed to condition the machine for subsequent keyboard digit setup operations Whenthe Vkeyboard operations for verification have been completed.
Underlying the keys |00 is a bail I03which operates to close a bail contact |04, such construction being well known. In starting, the rst key depression causes a circuit to be closed from current supply line |05 through the bail contact |04, through relay contacts BRI now closed, (Fig. 1a) line |06,- through relay contacts TRI now in the position shown, C2|| now closed, tov relay coil Cl, to ground. Relay contacts CI-I4 close to provide aV stick circuit back to line |06 andr relay CI opens contacts CI-II and closes' contacts CI--I2. -The closure of the latter closes a circuit from line |06 through C||2 contacts to relay coil TR to ground. Relay coil TR shifts its contacts TRI but since contactsCI--IIv are open the circuit to the C2 relay coil is opened and the latter is when the bail contacts open upon the release of the pressure on the depressed key,`relay CI deenergizes but relay TR remains operated.. Upon stickl circuit back to line |05.
the next key .depression the circuit extends from li'ne |06 through relay contacts TRI, relay contacts CI-II now closed to relay coil C2 to ground, stick contacts C2|4 providing the Relay coil C2 closes its contacts'CZ-IZ to energize pickup coil P of grounded relay coil TD, which opens its contacts TDI to break the stick circuit of relay coil TR, which deenergizes. Relay coil TD closes contacts TD2 to provide a hold circuit to line 9E to insure that it is energized long enough to deenergize relay coil TR. 'Ihe return of relay contacts TRI to normal does not cause relay coil CI to energize because of the opening of relay contacts C2--II. It is thu's seen that on odd key depressions, relay coil CI is energized while upon all even key depressions relay coil C2 is energized. As will be later explained relays CI and C2 have their contacts in alternate columns of the storage units, with contacts of Cl in all odd columns and with contacts of C2 in all even columns. Thus, upon the first key depression, closure of contacts CI-I (Fig. 1c) provides circuit to column I of the relay storage unit.
The contacts |01 (Fig. lb) are closed by the respective keys and a circuit is extended from line |05, through bail contacts |04, relay contacts BR2 now closed, (Fig. lb) and line 08 to one side of all of these contacts. other side of these contacts there are respective wire connections |09 to relays KC|--KC9, one `relay for each key, which relays are grounded so that a depression of a key will energize its KC relay and close respective KC4 contacts.
When the bail contact |04 closes a-circuit is extended from line |05, by line IIO (Figs. 1a, lb) to relay COM toy ground. Relay COM transfers its contacts COMI (Fig. la)'and thus a circuit is completed from line |05, through contacts COMI to relay coil CB to ground, and v also from contacts COM3 to a Wire ||2 which is connected to all of the KC contacts. When "I'D relay (Fig. la) energizes its hold coil H will closeits stick contacts TD2 (Fig. la) to provide a stick circuit by wire 96, through COM3 contacts back to line |05.
It will be noted that the KCI-KCS contacts have 'wire connections to grounded relay coils `KI-K4 through the normally closed relay contacts R3, |-4 and the connections are such so as to energize relays KI to.K4 singly orTi combinations according to the following code;
Key Relay Hence the KCI-I. to KC9--I and 2 contacts From the f energize the KI--K4 relays singly or in combination. The depression of the 0 key merely closes bail contacts 95 and bailcontacts |04 to energize CI or C2, depending upon whether the key depression is an -odd or even numbered key depression.
It will be noted that-to illustrate the present invention eleven storage units for storage columns I-II are shown, but the number may be varied. It will be observed then that in the depression of key 1" relay KI closes its contacts in each storage unit, closing KI-I contacts for column to KI-II contacts in column |I.l The same is true for the other K2, K3, K4 relays so that for each key depression contacts will be closed in all of the eleven columns of the storage units upon each key depression.
I2, I3, and I4 are selected for energization by closure of respective contacts KI-I, K2-I, K3-I, and K4-|. Similar relays are provided for each column of the storage unit, relay coils 2|-24 for column 2 being provided. The tens (and hundreds) digit is provided to indicate the column number and the units digit to indicate the relay number. Hence 52 indicates relay 2 in column 5; |I4 represents relay 4 of column II. Therefore, closure of KI relay contacts in the storage units energizes relays |4 singly or in combination but only in the storage column selected for operation are such contactseffective for digit setup.
Upon the first key depression contacts CI-I (Fig. 1c) are closed so that an energizing circuit for relays |-4 of storage column I is provided from line |05, through supplemental bail contacts 95, (Fig. 1b), through CB2 contacts now closed, lower relay contacts R2A2 now closed, relay contacts CI-I now closed, B2 contacts now closed to line I I3, through relay contacts R3`I, the relay contacts PI2 now closed, wire |I5, to'the particular KI-K4 contacts closed to the respective II-I4 relays to line I|6, to ground.
Having been energized the relays II-I4 are held energized as follows: It will be noted that relays |-4 in each unit are of the doublev type consisting of a pickup coil P and a hold coil H with the contacts adjacent marked. H being the conventional stick or hold' contacts which are closed when the pickup winding is energized. The stick circuit for relays I|-I4 extends from ground, through the relay, its H contacts and wire II'I, through DOI-I contacts to line |05.
It will be noted that from line I|3 a circuit extends to grounded pickup relay coil A which closes its contacts AI and which prepares column 2 of the storage circuit for entry of a storage 1mpulse upon the second key depression, the impulse now being directed from KIf-2, K4-2 contacts to energize relay coils 2|-24. It is to be noted that the stick circuit line for these relays also extends by wire IIl back through contacts DOI-I and hence columns I and 2 are section-v alized and constitute a sub-division.
Relay coil A closes its H stick contacts, the stick circuit extending back by line I I8 (Fig. 1b) through relay contacts R2-9, land wire |20 to the line |05.
While relay contacts AI are closed the digit impulse on the first key depression cannot be transmitted to relays 2|-24 of the second column even though KI-2 to K4-2 contacts are closed because C2-I contacts are open. However, on the second key depression relay coil C2 energizes to close contacts C2| and the second column will be set up, and in this case relay coil B energizes to open contacts 'B2 of the first storage unit to prevent setting up of column storage unit on subsequent odd key depressions and closes contacts BI in the column 3 of the storage unit, preparing it to receive the third digit set up. Relay coil C energizes for the digit set up in column 3 opening contacts C2 to prevent `a setup in column 2 and closing contacts CI preparatory for a digit set u-p in column 4. In the same manner digit setup ensues for the eleven storage columns.
Relay coil B also closes its-respective H" stick contacts to connect the relay to the hold stick circuit line ||8 and such column relays are held energized until released at a later time in machine operations, when relay coil R2 is deener- The stick circuits for column relays of allcolumns are sub-divided as follows:
Storage columns Relay coil R2 contacts Nora-No relay coil is usedfor the last column, as
it is unnecessary.
Similarly the stick circuits for the I-4 relays of all columns are sub-divided as follows:
Storage columns no1-1 (Fig-1c) Doz-1 (Fig. 1a) D 03-1 (Fig. le)
The impulse circuit for setting vup the storage I relays of column I will vbe described as itdiffers. Since column II is an odd numbered column, relay coil CI is energized.

It will be noted that line |23-connects one side of the above relay contacts, the wire extendingback in Figs. 1f, e, d, c, b, a, in the order named through,contacts EIO-9 (Fig. 1a)` now closed, relay contacts E||2 now closed'in a manner to beexplained, Wirev |24 to line |05. Relay coil E8 closes its contacts E8-I extending the circuit connection by wire |22 to groundedA relay-coil EI I, and also EI IA in parallel therewith. Relay coil EI IV transfers the related contacts Ell-2 and as such contacts transfer, a
vcircuit is closed from line |24 throughl Ell-2 contacts to relay coil R2A to ground. 'I'he latter closes its contacts R2A3 to energize relay coil R2. The latter opens its contacts R2-9, 8, 1 and 6 (Fig-lb), opening the stick circuit of the pre- Y viously energized relays A- J.
D04-1 (Fig. le)
If the error key 'is depressed after. an even key depression relay coil R2 opens'itsRZ-I contacts tacts EI IAI now closed to the pickupA relay coil of relay RI. The latter closes its contacts RI--3 to send an impulse to R2A relay coil. Now referring. to Fig. 1b the storage impulse is directed :trom CB2 contacts now closed, through relay contacts R2A2 now transferred to wire 250 (Figs.
1b, c, d, e, inthe order named) through the KI-I I, K4-II contacts to the III-|14 storagerelays.
Error key operation vIf at any time during the initial-digit set up the operator discerns that an error has vbeen made, the Error key (Fig. lb) is depressed to close its-contacts IIS, extending acircuit from line |05 through contacts |I9, line |2I (Fig. 1a) to relay E8 to ground. A circuit is also closed from line I2 I through relay contacts R3AI, relay 4 contacts PI-I., relay contacts Ell- 2 vto relay-coil EIO to ground. y
The impulse to energize relay coilEB is transmltted to the pickup coil of relay coil EBA. The
latter opens to safety contacts EBAI (Fig. 1f) yto prevent an unwanted impulse from being directed upon an error key depression to relay coil SEA, to be later referred to. The relaycoil E8A closes its hold contacts E8A4 (Figi. la) and the circuit then extends by wire |94 (Figs. la, b, c, d, e, f, g, inthe order named) to contacts 221 in the punching machine now closed, contacts CLI now closed, contacts |84 now closed; back to line |05.` The stick circuit remains closed untilcontacts -22'IA open in a manner to be subsequently explained. From Fig. .1f it will be noted that when column I is set up, relay contacts A3 close; when column 3 is set up, relay contacts C3 close; when column S is set up relay contacts F3 close and when co1 umn I0 is set up, relay contacts J3 close and hence as many as the above contacts are closed as storage 'columns are set up. Each of the above (Fig.- 1b) thus breaking the previously described holding' circuit for the previously energized relay coil TR., deenergizing the latter so vthat upon the next key depression vfor setting up column I an impulse will be vdirected to the CI relay coil, which is essential in lsetting up column I. l
I Initiation-'of verifying operations Initiation of verifying operations is effected i when a storage of a. digit is effected in the last storagecolumn; namely', the eleventh column and in the storage operation .for the preceding column I0 relayJ is energized and heldv energized. Since column II is an odd numbered column, relay CI is energized when a key stroke is effected. for this column. As previously described, a circuit is then completed uponmaking the key stroke for column II from line- |05 (Fig.` 1c) wire |24, through relay contacts EI`|-2, relay c'ontacts MBRZnow'closed, relay contacts vC0M2 now shifted andclosed because of the key stroke operation energizing re1ay ,.-,COM as previously described, relay contactsgCI-I3 now closed, relay contacts JI now closed, relay con;

When` the key depressed for effecting the digit set up in storage column II is released, re-
lay contacts COM2 return to normal and when the left set of relay contacts comes to normal a circuit is completed from line |05, wire I 24, relay contacts EII-2, through relay contacts MBR2,
the-left set of relay contacts COMZ now closed, through relay contacts RI-I now closed by energized relay RI to grounded relay coil R3A and R3 in parallel therewith and both grounded. The hold circuit for relay coils R3, R3A is through the stick relay contacts R3A4, relay contacts MBR2, relay contacts EI I2, wire |24 back to line |05. Relay contacts R3A2 transfer, preparwith each relay AC, BC C there is a related relay contact closed by relay R3. For storage column I there is a contact R3-1; for storage column 2 there is a contact R3-8, etc. to relay contacts R3-I1 for storage column II. Hence relay contacts R3-1 to R3-I1 are all now closed.
Verifying operations During verification the operator makes the same key strokes as in setting upthe digits in the storage units to check the digit set up therein, and also to determine whether the data for the original data sheet has been correctly interpreted and the proper digit setup made.
Reference has been made to the circuits for effecting the successive energization of relays A-J and with relay contacts R3--1 to R3-I1 now transferred, the energizing impulse not only passes to relay A (Fig. 1c) but also to one Winding of a duo-coil'relay AC (for storage column I by way of explanation). Therefore, A-J relays successively energize for column spacing during verification and one winding of duo-coil relays AC-KC also successively energize. The circuit for energizing the KC relay will be explained later. It will be noted that each relay AC-,-KC transfers its set of relay contacts I 4, relay contacts'ACI-4 (Fig. lc) first closing, then relay v no relay is operated on the vertiiicatio'n key operation.
contacts BCI-4 upon the second verifying key operation, and 'then successively to KCI-4 con- It will be recalled that during key depressions selectively energized, but now that relay contacts R3--V-I--4 (Fig. 1b) are transferred the key impulses are transmitted to relay coils CKI to CK4 and these are energized singly or in combination according to the adopted code. However, the other circuits previouslyv described in connection with keyboard operations are made; that is, the sequential energization oi relays CI, C2, and the energization of relays COM, CB. Each time relay coil CB energizes, a circuit is closed from line |05, through lower relay contacts CBI, (Fig. la) and by line |25 is extended to grounded relay coil CI. Relay coil CI closes contacts C12 (Fig. 1b) providing a stick circuit for the energized OKI- 0K4 relay through their 4 contacts, through CI2 contacts, wire |20 back to line |05.
An irnpulsing circuit for vertification is extended fmm line |05, wire |20 (Fig, 1b) through relay contacts CII now closed, to lower relay contacts CP3-I in the position shown and from such contacts the circuit extends through the upper relay contacts CP3,'2,- CPS-3, CP3-4, and
All of these are nowclosed in this op*- eration as shown and thence the circuit extends to the center blade of relay contacts CKI-I,
'CK2-I, CK3-I or CK4-I and to lines |30, I, 2,
3 and 4 or I3I, I, 2, 3, 4, depending upon the transferred or normal position of the last mentioned contacts.
The manner of verifying operations can best be understood by reference to a specific digit set up, such as 1 in the I storage column. It will for the initial digit set up relays KI to K4 were be noted that reiey eene I l, l2, is and 'u transso that the verifying impulse is transmitted to line I30-I but due to the transferred contacts I I -I, the circuit is open at this contact position. However, if the repeat key depression should be 2, contacts CK2- I would be transferred and the lverifying impulse will. be transmitted to line |301,iandlsincat? was previously set. up, ,contacts IZ-I are normal so lthat the circuit extends through such contacts, through AC3 contacts now closed, to line |32, (Figs. 1c, d, e, in the order named) through relay contacts CP38 to grounded relay coil PE. Relay coil PE closes its contacts y PE3 (Fig. 1f) in a local .lamp circuit, thus illuminating lamp |33 indicating an error in verification.
At the same time an impulse is sentv to each of the lines |30, I, 2, 3 and 4 to the normally closed side of the contacts II-I, 2, 3 and 4, an impulse is sent to each of the lines I3I, I, 2, 3, and 4 to the normally open sides of the contacts I |-'I, 2,
3 and 4. If any of these contacts are closed, in-
dicating that a relay II, I2, I3, I4 which does not correspond Ato any of the relays II, I2, I3, I4 which was energized during the nrst digit set up, an error indication will result. It will be `thus seen that an error test circuit is provided to indicate an error both where a relay has not been previously operated which should agree, with the relay set up in the verification key operation, and where a relay was previously operated for which The verification proceeds as above for each column, stepping from column to column in a man ner similar to that employed in the initial setup.
Upon the very rst indication of an error, relay PE `energizes to close contacts PE3 (Fig. 1f) in a local circuit of flash lamp |33 and such relay is held energized by a.v stick circuit through.
stick relay contacts PE4, lower relay contacts E8-4 back to line |05. It will be recalled that the relay coil E8 for opening such contacts is contacts controlled by relays 1I to 14 .of storage column 1. These verifying impulse circuits could, of course, extend for verication of columns 8, 9, I0 and II but to prevent possible misoperations which will be more evident later on, it is preferable to provide a supplemental set of verifying impulse circuits for storage columns 8, 9, I0 and From Fig. 1b, it will be evident that the verifying impulse relay contact CII is not only directed to CP3-iI contacts but by a wire |26, the impulse is extended through the lower relay contacts CP4-I, the impulse then extending through relay contacts CP4, |-4 which are now in the position shown, thence to the center blade of relay contacts OKI-2, CK2-2, CK3-2,
CK4-2 which contacts are also closed by the The supplemental verifying CKI-CK4 relays.
feed impulse lines consist of a set of lines |26 similar to the impulse lines |30 and a set of impulse lines |21 which lines are similar to the lines I3I in respect to their connections to the con- '8,9, Iandll.'
tacts controlled by the storage relays I, 2, 3, 4 of columns, 9, I and II.
It is clear, therefore, that after storage column .1 has been verified, theverifying impulses are directed-by the lines |26 and 21 to verify the digit setup of columns 8, 9, I0 and I. 0f course, these verifying impulses are also sent to the lines and I3I but they are ineffective because the AC I vto GC contacts remain open and it is only the impulses directed by the sets of lines |26 and |21 through the successively closed HC-KC contacts that are effective for verifying'storage columns When an error has been located inl any of the storage columns 8, 9, I0 and II by the verifying circuits operating in the manner previously described, an impulse is transmitted to the Wire |28 (Figs. 1d, le) which passes through the contacts CP4--8, now in the,position shown in Fig. le to the PE relay, which relay, upon its energization, as described, causes -the illumination ofthe signal light I 33, indicating an error in 4Verification.
Audible indication of er1-orf in verification Energization of relay coil PE closes relay contacts PE2 (Fig. 1a) so that while the key depressed in the verifying operation indicating an error is heldk down to energize relay'CB, the transfer of CBI contacts from the position shown in Fig. 1a transmits a circuit from line I 05 through lower contacts CBI, along wire |25, through contacts FEZ to grounded Buzzer, which gives the audible indication of an error in verification during the key stroke the error was ascertained. When the depressed key isreleased a circuit 'is closed from line |05, through upper contacts CBI, Wire I 34, relay contacts PEI, to grounded relay BR. A hold circuit for the latter is completed from the hold relay coll through stick contacts BRG, relay contacts Eil- 2, wire |36, wire 99 (see Fig. 1f) switch 98, Wire 91, back to line |05. Relay contacts BR3 (Fig..'1a),close so that for each succeeding key-depression after an error in verification is ascertained a circuit isv` completed to Buzzer through contacts CBI, wire |25, relay contacts BR3, to BuzzenI Also to prevent further verifying operations upon succeeding key depressions, relay contacts BRI, (Fig. la) BRZ, (Fig. 1b) are opened so that no circuit closed by the bail contacts |04 can be Vmade by successive key strokes.
Selective clearance of storage units in particular sub-division error was ascertained Thenumber of sub-divisions provided can be varied and can even be sub-divided to provide for rectification of only a single column, but it is desirable, however, to "subedivide according to elds so that the related data of a field may be corrected in `accordance with the original data sheet.
Therefore, the operator may then make an initial setup for those storage units found to be incorrect, followed by repeat key depression for digit setting in those storage units for purposes of verication.
When the error key (Fig. 1b) is depressed following the determination of an error in the digit setup of a storage unit, the circuits previously described -are closed to energize relays E8, EII, and EIIA (Fig. la), Relay coils E8, EII, and EIIA are energized by the circuitspreviously described, but since R3Ais energized during the verifying operations the transfer of relay contacts RBAI causesthe impulse by wire I2I which energizes E8 to also be directed to grounded relay E9 but not to'relay RIO. The stick circuit for relay coil E9 is provided by stick contacts Ell-I0, wire |30,
through relay contacts MBRI, wire 99,-which it willbe recalled extends back to line |05. Relay E8 transfers its contacts E82^to deenergize BR relay, and relay contacts E8-4 (Fig. 1e) open the stick circuit to PE relay, which` opens its PE3 contacts (Fig.1f) to extinguish lamp |33.
When relay contacts E8-I close (Fig. 1a), a circuit is completed from line I2I through relay contacts E8-I, relay contacts R3A3 now-closed, and thence through one or more contacts P4-I,
P3-I, P2-I which-are at normal and thence to a certain' one of or E4.

cessive energization of relays AC-KC as successive columns are veried. It will also be noted that the impulse which is directed through relay contacts R3--9 (Fig. 1c) to energize relay vCC of the third column is also transmitted by al wire |42 through relay contacts DOI-2 now closed, to grounded relay coil PI. is energized when the third storage column has been verified. A stick circuit to hold relay PI 'energized is through its hold contacts PI-4, wire |43, wire I I1, through DOI-I contacts now closed these columns the depression of the errorke'y' will result in the energization of relays EI, E2, E3 and E4 and the closing of relay contacts EI-3 'and E2-3, E3--3 and E4-4 (Fig. 1f) The relay I E8 being energized bythe depression of the error key will transfer 'its E8-2 (Fig. 1a) contacts to cause a circuit to be completed from line |05, wire 91, (Fig. 1f) switch 98, Wire 99 (Figs. 1f, e, d, c,
lb, a, in order named), wire |36, contacts E8--2 now transferred, wire |31 (Figs. la, b, c, d. e, f,
in order named.) through relay contacts EI--3, to grounded DOI relay coil. Also a circuit is' completed through E8-4 contacts 'now transferred (Fig. 1f), relay contacts E2--3, now closed, to grounded'relay D02. A circuitfis also completed through relay contacts EI I-3, now closed (Fig.V V1f),-through relay contacts E3-3 now closed, to grounded relay coil D03. An impulse to energize relay D04 is from line |05, through closed relay contacts E8--3 (Fig. 1f), relay contacts E4--3 now closed, to grounded relay coil All of these relays DOI, D02, D03, D04 open their contacts DOI-I (Fig. 1c), DO2-I (Fig. le), thereby clearing storage units of columns I-II inclusive,
Therefore, relay coil PI The opening of contacts DOI-I (Fig. 1c) breaks the stick circuit for relay coil- PI, and opening of contacts DOI- 2 prevents the pickup of relay coil PI.
It will be assumed `that the field comprismg columns has been verified as correct but an errorl is located in the setup of columns 69 which comprise the next iield. When the impulse'for energizing relay coil FC (Fig. 1d) is transmitted thereto upon verifying the sixth column, an imilcation of these columns to prevent the test circuit impulse from energizing either'El or E2 relays. However, the testcireuit impulseinitiated 20 by the depression of the error key passes through relay contacts P4| to relay coil E4 and also through contacts P3| to grounded relay coil E3. 'I'he latter close their contacts E4-3 and contacts Ell- 3 (Flg.f1f), a'circuit is closed through relay contacts Elly- 3, E3-3 to relay coil D03 and also through relay contacts E8--3 now closed, through E4--3 relay contacts to tive contacts El-z, .Ez- 2, Es-z l(rig. 1b),`
and such relay contacts are provided for the purpose of retaining the column relays A-I energized which pertain tothe storage columns which have been veriiied as having been correct in their digit setup. Upon the depression of the error key, the relay R2 (Fig. la) energizes as previously described and opens its contacts ft2-6, 8, and 9, always opening, by relay contacts RZ-S, the stick circuit for column relay J but tending to open all of the stick circuits for `the column relays A--I for the iirst nine storage columns but, of course, the column relays pertaining to the storage columns which have been veriiied as correct which can only be column relays A-I should not be deenerglzed and the stick circuit for such column relaysl is maintained by the 2 contacts of the El-E3 relays which remain deenergized.
For example, when an error is found in th digit setup for columns to 5,`relayvcoils El, E2, E3 are energized and such relays open their 2 contacts shown in Fig. 1b. It will be recalled that upon the error key operation, relay coil R2 E3--3 (Fg- 1f) S0111 upon clos-ure of relay 2,5 is energized, thereby. opening the relay contacts- R2-6, 8, 3, thus opening the holding circuits for column relays A-J of storage columns ||0.
It will also be recalled that upon the error key operation the relay coil E9 is energized to close relay coil'DO4. The latter opens their contacts 30 its contacts *E9 3' 4 5 In the assumed ex umns -I I inclusive without, however, affecting the verified digit setup in columns |5.
Obviously, in'the same manner when storage column |0 is verified, relay coil P3 (Fig. le) is 35 energized and remains energized by a stick'circuit like that described for relay coil P2. The
.opening of contacts P3-| (Fig. la) enables only relay coil E4 to be energized by the test circuit so that only relay coil D04 .(Fig. a1f) is energized 40 in this instance to clear out Vthe storage columns |0 and Il.
For safety in operations, an alternative stick circuit to retain relays P2 and P3 energized is ample, the 2 contacts controlled by the El, E2,A
E3, relays are opened so th'at even though the relay contacts of relay coil E9 are now closed, all of the stick circuits for the column relays A-J are opened. I
It will. now be assumed that columns |5 -which include columnrelays A-Ehave been provided because when D04 relay energizes on 45 during the verifying voperation -clears out the storage columns of th'e ii/eld in which an error is locatedA and-.as shownpreferably clears out the storage columns of unveried fields. However, those storage columns which have been verified as correct remain untouched and their digit setup remains. s
Whenever relays El', E2, E3, E4 are energized by the selective, circuits,A previously described, their pickup and' hold coils close their 4 stick .contacts (Fig. la) thereby extending the stick circuit for the selectively energized relays through the stick contacts and thence via wire |50, wire |39, through relay contacts MBRI,
lf back vto the line |05. By the above holding circuits, the particular relays El through E4 which have been energized remain energized, such selective energization being according to the circumstances previously described.
Relay coils El throughI E3 open their respecveriiied as correct butl an error is located in one of the columns 6. 1, 8 or 9 and according to the present embodiment this should result in the deenergization of the column relays F-J associated with storage columns 6|0. When an error is found in one of the columns 6-9, relay coil E3 is energized which' will open its contacts E3--2, thereby opening the stick circuit for theA columnrelays F-I. Relay contacts R2-6 open the stick circuit for column relay J. However, for columns to 5, it will be noted that even though contacts R2--9 and R2-8 open, the stick circuit for column relays A and B will be maintained through relay contacts E|2 now closed, thence through E9-3 contacts back to the line |20. The stick circuit for column relays C, D and E will be maintained through relay contacts E2-2 and relay contacts Eil-4.
When an error is found in one of the columns I0 and Il, relay coil R2 will open its contacts R26, thereby opening the circuit for the column relay J of column I0, but relay contacts E|-2,
Yfor column relays A-I. It will also be remembered that there is no column relay provided for the last column I so that in the absence of such a column relay, it is unnecessary to effect its deenergization as is provided for'in column I0.
Therefore, irrespective of the opening of the contacts controlled by the R2 relay tending to' open all the holding circuits, the shunt 2 contacts controlled by the El, E2, E3 relays will continue the holding circuits for the column relays pertaining to those columns which have vbeen verified as correct, such holding circuits being maintained through the contacts closed by the E9 relay.
In order to insure that the alternating circuit for causing the energization of lrelays CI and C2 will have the proper relation when the storage columns are' reset after the verifying oper.
ation for such columns has determined an error, the special circuit shown in Fig. 1a has been provided. As explained, it is pointed out that if an error is found in storagecolumns I to 5, the clearing out of such storage columns and the subsequent digit set up requires that relay Cl be energized since the first stored column is to be column I. On the other hand, when columns S to 9 are to be reset when an error has been determined insetting up one of these columns, it is necessary that the setting up of the storage columns be controlled by the energization of the C2 relay since the first column set up is column 6 which is an even numbered column. The same condition obtains with' columns I0 and Il as is found for columns 6to 9, that is, relay C2 must be energized because in the restorage of the digits for storage columns I and Il', the
,first column is column I0 which is anv even numbered column.
Contacts EI-l, E2-I', E3| and E4| are interconnected and wired as shown in Fig. 1a and such contacts are transferred from their normal position inl accordance with the energization of the relays EI through E4.
When an error 'has been found in any of the columns I to E, the relays El, E2, E3 and E4 are all energized so that all of their fl 'contacts are transferred. Upon the depression of the error key, relay coil R2 is energized as previously described, causing the transfer of contacts R2-2, thereby extending the circuit from the line |05, wire |45, through lefthand relay contacts R2-2, thence serially through the depression following the depression of the error key,"it being noted that for columns I0 and Il relay coil E4 is energized, thereby transferring its contacts E4-I. The impulse will pass from transferred relay contacts R2-2, thence through transferred contacts E4-I, thence through lthe upper relay contactsES-l to the relay coil TR.
Hence, the rst digit set up will be made for storage column I0.
It' will be recalled that' the stick circuit for relay coil TR is through the stick contacts TR4, through contacts TDI and thence through relay contacts RZ-f-I and relay contacts MBRI, wire 99, back to line |05. It will also be remembered that upon the depression of the error key, relay coil R is energized which will open its contacts R2 and since this will result in the opening of the stick circuit, safety contacts E9| are provided and such contacts shunt relay contacts R2--I and insure that .the stick circuit will be -maintained through relay contacts RZ-l upon the completion of the depression of the error key.
- Manual bar operation lgized and upon verifying the eleventh storage column relay coil CI is energized because this storage column is odd-numbered. When relay contacts CI-I3 (Fig. la) are closed byrelay coil CI and with relay contacts J I already closed,-
El-I to the pickup coil of the relay TD, thereby venergizing relay coil TD and causing the opening of the stick contacts TDI. The opening of such contacts will result in the deenergizing of the stick circuit for the TR relay and in view of the deenergization of the TR relay contacts TRI will restore to the normal position shown. This is the normal position of the contacts and the controlling circuit when ,thel first digit setup is made and therefore, upon the first digit set up following the depression of the error key, relay coil CI will be energized andthe digit set up will be, made in storage column I.
When an error is located in any of the columns B to 9, the assurance that the first storage digit set up following depression of the error key is effected in column 6 which is an even numbered a circuit' is completed from line |05, via. wire.
|24,` through relay contacts EI I-2 now in normal position, through relay contacts MBR! now' closed, thence through transferred relayv contacts COM2 which close upon the depression of column is made by the wiring of the 1 relay i contacts controlled by the E relays. When an error is located in any of the columns 6 to 9, inclusive, relay coils E4 and E3 will be energized, thereby transferring their 1 contacts so' that the impulse circuit from transferred relay con- 'tactsRZ---v will pass through transferred coneffected to cause the ener-- `the key for verifying the last storage column, the
circuit then extending through relay contacts CI-I3, relay contacts J I, thence through the left relay contacts R3A2 which are now closed, to grounded relay coil R4; resulting in the energizatlon of this relay coil and relaycoilRIA in parallel therewith-l Relay contacts R3A2 are transferred at this time because the machine operation is a verifying operation'.- Relay contacts R4A4-are stick contacts, thereby providing a stick circuit through these contacts and via wire |65, (Figs. la, b; c, d, e, in the order named) through left relay Vcontacts EI |-4 now in the position shown, thence through relay contacts D04- 2, back to the line |05. Hence, relays 4 and IIA` are energized by the last key stroke of the verifying operation and relay coil 4A, instead of deenergizing upon release of the. last key. struck, holds until the end of the card punching R4 is energized. during the last Verifying key stroke, relay contacts R4--3 (Fig. ,16) are closed so that the impulse circuit is from line |05,
tacts R3-'|'l now closed, to grounded KC relay coil.
A warning signal is given to the operator in the event that the manual bar is depressed before verifying the last storage column. Upon the depression of the manual bar a circuit is closed from the line |05 and via wire |68 (Fig. 1a) thel circuitis extended to the contacts which are closed upon the depression of the motor bar "|||2. The circuit then extends from such contacts via wire |61 to relay contacts R4A| (Fi'g. la) If the last storage column, namely column |I, has not 'been verified, relay coil RJA will not be energized and therefore contacts RIAI will be in the position shown so that the circuit will extend through the left hand contacts and via wire |68 (Figs. 1a, b, c', d, e, f, in the order named) to grounded relay coil PE.. Reference has been previously made to this relay and it will be recalledthat it was described as having the function of f lighting an errorsignal lamp |33,
and also to-complete a circuit to the Buzzer show n -in Fig. 1a. In theZ same manner and by the same circuits both of these signals will be given inthe event that the operator depresses the manual bar before the last column has been veriiled. y
If the last storage column has been veriiied,
' relay contacts RIAI (Fig. 1a) 4will have been transferred so that the circuit will extend from the wire |51, then through the right hand contacts RAAI` to a wire |69, the circuit-then extendingthrough.relay contacts BRI now closed and to grounded relay coil MBR.' The latter closes its contacts MBRB sothat the circuit is extended through such contacts to relay vcoil erence card columns it will be understood that these refer to the columns of the card. While..
the punching `operation could be initiated when the digit setup of all the storage columns have been verified, saving in time in machine operations will be made by having card punching operations automatically ensue upon the completion of verification of the digit setup of some of the storagerelays. For this reason the circuits are arranged so that upon completion of the verification of one sub-division, punching is automatically effected under control of the storage relays for that sub-division and while-punching operations are being effected, the operator goes through the repeat key depressions to determine whether the next subdivision'of relay storage de- R2A. The latter closes vits contacts R2A3 to v energize relay R2. The opening of contacts R2, 6, 1, 8 and 9 by R2 relay(Fig. 1b) will break the holding circuits of the column relays A through J in= the manner previously described.
The opening of the relay contacts MIBRI shown in Fig. 1a breaks the holding circuit for the relay coil TR so'that if this relay had been lett in its energized condition by the last key stroke, the following storage digit setup operations could take place with relay coil C| operating first as is necessary for correct sequencing. The transfer of relay contacts MBRI also break the stick circuit for relaycoil E9 and also the stick circuit for all of the relay coils El, E2, E3
and El which may have been previously energized. The closure of the right hand relay contacts extends'a circuit from the line |05 by wire 99 through the right hand relay contacts MBRI, thence via wire |12 (Figs. 1a, b, c, d, e, in the order named) thence-via wire |12 which extends to the grounded relay. coil P4, thereby causing the energization of this relay coil. The stick circuit provided for this coil is through contacts Pl--I to the aforementioned holding circuit line Punching mechanism As previously intimated, a punching mechanism is 4providedl whereby a card may be punched to represent 'the 'data which is 'stored up in the storage relay devices compris- -ing, in the present'machine, eleven columns. The card which is to be punched is shown in Fig. 3 wherein it will be noted that the first nine columns have been prepunched to represent -common data for a series of cards so that the punching of the digit set up on the storage relay devices commences from column l0 and continues successively through column 20 of this card. It will be noted, therefore. that columns to of the storage devices control punching of columns l0 to 20 of the card and in the refvices is correct in its digit setup. When this subdivision has been verified and it has been determined that its digit lsetup is correct thev punching operation is then initiated to punch the data pertaining tol the next sub-division. This mode of operation continues until all of the-card columns have been punched out under control of the storage relays. Tabulated, the punching operations are effected as follows:
t Storage Card I Upon completion oi Relay coil columns columns verification of column energized read out punched P1 l, 2 l0, l1 P2 3, 4, 5 12, 13, 14 P3 6, 7, 8, 9 l5, 16, 17, 18 P4 l0, ll m Any suitable .type of punching mechanism may be provided for digit recording and other forms of recording machines may be utilized-but preferably a punching machine of the type shown in the patenit to F. Lee 'et al., 1,976,618 is utilized. The punching machine is generally shown in Fig.= 4 but .n-ot in full detail as lin this patent, to which recourse may be had for fullinform-ation. Later on a general operation of the punching machine will begiven in connection with the wiring diagram. At the prent, it is only necessary to understand that the machine includes a series of punches which punch cards according to the Hollerith system and the Apunching operations areeifected successively by theprovision of a card carriage which escapes column by column as the successive punching operations ensue. As-
is also well known, in the form of punching machine lreferred to `a. skipping' mechanism is provided where certain card columns of the card may be skippedpast the card punches' without punching operations being effected for such card columns. In the present machine all of the cards are punchedl in the first nine columns with data which is common to-a series of Vcards and by means vofthis vwell know'n skipping mechanism the card carriage, when it isretumed to column f |,ra1rtomatically skips `to column l0, in which position .the card carriage is-in when the operator has completely verifled the digit set up. in storage columns and 2. Hence, the punching 'machine is picked up for punching operations upon completion of verification in columns and 2 so as to punch card columns I0 and this being one of the sub-divisions previously referred to ing machine shown in this patent punches cards according to the Hollerith system, that is, a perforation is placed at a differential location to represent the digits set up in the storage columns.
lIt should also be understood that the punchinclusive.
For reason, the combinational setting of the relays must be translated to-a single digit representation. Such forms 'of translators are well known and briefly for storage column the energized relays Il, I2, I3 and I4 (top of Fig. 1c) Y transfer their respective 2, 3, or 4 contacts and such contactsare closed in combination in accordance with the code,v and being interconnected in combination select one of a series of digit lines |80 (Fig. 1c to Fig. 1g) which are marked 0 to 9I The digit lines |80 are connected to grounded punch magnets |82 (Fig. 1y and Fig. 4)
points |89 and |9| ofthe .two sets. Some ofthe contactpoints are not wired although they are shown in Fig. 1f but those which are wired make and vsuchpunch selecting magnets correspond to the punch selecting magnets 60 of the 'aforementioned Patent No. 1,976,618. Therefore, according to the particular contacts of the translator which are open and closed, oneof the digit lines will be selected so as to select for energization the desired one of the punch selecting magnets |82. It should also be noted that'in the event that none of the digits 1Vto 9.are stored in a particular storage column all therelay contacts of the translator relating to that storage column will be at normal position so that' normally the "0 punch selecting magnet I 82 will be selected for operation. Talnng for y example storage col- 'umn I (Fig. 1c) it will be'noted that due to the normal closure of contacts II--2, |22, |3--2 and |4-2 in the translator for'column I I, the
readout line |83 for this .column will have a normal connection through such relay contacts to 'the 0 digit line |80,thereby selecting .the 0 punch selecting magnet |82 for energization. If other relay contacts in this translator are closed, another circuit will be closed from the line |83 through such contacts so as to` select the appropriate digit line |80.
The line |83 for the rst storage column is the readout line for the translator of storage column I; that is to say, when vthis circuit is closed, the initiation of the punching machine Will be effected vso as to punch card circuit connections explained.
When the key stroke for verificationof column 3 is maderelay PI .(Fig.' 1c) is energized and this results in the closure of 'relay contacts PI-J (Fig. 1c) The previous skipping of the card carriag'e to column l0 now provides a circuit from line |05 through contacts |84 now closed, thence which will be subsequently .through relay contacts CLI closed in a manner to be 'subsequently explained, thence through contacts |85, wire 81, .to the vbrush |88 (Fig. 1j) contacting the contact point |89 at thegtenth column position, thence to'grounded relay coil B2 andthe latter energizes and closes its contacts B2'-'| (Fig. 1c). It will be understood that at any column position of the carriage the brushes l |88 complete a circuit from line |05 to the contact point |89 or |9I it engages. VIn the circuit now being .considered for punching card column l0, it will be seen that from Wire I 83 (Fig. 1c)
.connected to the translator of storage column I contactsBZ-I and' PI--3 are in series connection therewith and by wire |94 (Figs-1c, d, e, f, g, in the order named), the circuit extends through contacts 221 nowclosed, CLIcontacts controlled by the card lever control relay CL now energized to close its contacts in a manner to be subsequently explained, thence through contacts |84 now closed to linev 05. Contacts 221 are operated similar to contacts |85 and therefore are supplemental contacts operated like contacts |28 in Patent No. 1,976,618. In accordance with the setting ofa translator, -there is a circuit connection to the selected punch selecting'magnet |82. The
punch now perforates column I0 and the card 4 carriage escapes in the usual manner to columnv column I0 which is 'the' starting' card column position of the card carriage. Punching in card columnv I0 will b e effected when columns I and 2 have been verified and relay coil PI energized when storage column 3 has been verified. Initiation of punching operations and the suci cessive punching operations of the punching machinereferred to are effected under control of a device known as a column readout device which is well known in the form of punching machine described and is fully shown in Fig. 3 of the chine shown herein. Contacts |85 are similar in operation and function to contacts designated 1-28 in Patent No.v1,976,618. Both of the contacts|84 .and |85 are normally closed. The wire `connection |81 extendsto .the movable brush |88 (Fig. 1f) of the column readout device and the brush |88 consists of two sets of four brush strands.
In the present cas-e the column readout is of a duplex Vconstruction so Athat both brushes will contact with corresponding column contacts |89 and I9I and then as the card carriage steps col-- umn by column the two brushes will make successive contact with the corresponding contact AAt column lI I a circuit .is completed from the translatorbf storage column 2 by a wire |95 (Figs. 1c, d, e and f) connected as shown in Fig. 1f to the contact point |89 at the eleventh card column position.
Obviously, when storage colunms and 2-have been verified as correct, the keystroke for verication of column 3 causes the energization of relay coil PI and initiates punching of columns |0 and under control of storage columns and 2 as is 'clearly outlined in Fig. 5. While the card carriage escapes tov column |2 after punching card column the punching of card columns I2,
I3 and I4 does not take place unless the related storage columns 3, 4 and 5 have been veried and a key stroke is. made to verify column 6 which causes the energization of the relay coil P2 (Fig. ld) to close its'contacts P2-,3 (Fig. 1c')`. 'I'his .operation is also outlined in Fig. 5.
When contacts P2-3-close the translator'for storage column 3 (Fig. 1c) is then connected to the line |05 through contacts P2-3, wire |96 (Figs. 1c, d, e, and f) which wire is shown in Fig.V lf as connected to the column contact point |89 at column I2. 4The punch then punches card column |2 andthe card carriage escapes to co1-` umn |3. The translator of storage column 4 for punching card column |3 is connected to the line |05 by a Wire |91 (Figs. 1c, d, el and f) connected as shown in Fig. 1f to the column contact |89 at the thirteenth card column position. Thereafter the card carriage escapes to card column I4 and storage column 5 for punching card column I4 is connected to theline |05 by a Wire |98 (Figs.
'1d, e, and f) which is shownln Fig. lf as connected to the contact point |89 at the fourteenth card column position.` The card carriage then
