lNvENtroR 1e ATTORNEYS nited States Patent C) AUTGMATIC CODNG SYSTEM Merle E. Gould, Stamford, Conn., assignor to Seit Winding Clock Company, Inc., a Delaware corporation Application August 28, ,1953, Serial No. 377,091

22 Claims. (Cl. 197-1) The present invention relates to the art of automatic coding of recorded data.

Where a multiplicity of sequences of recorded data must be read and interpreted before they can be translated to a code, such as one to be used in automatic classifying equipment, the operation is time-consuming and requires much personnel with the likelihood of error (a) in the reading, (b) in the interpretation and (c) in the recording of the code designations. Checking to minimize such error entails further time consumption and necessitates further personnel.

Where the data is recorded on a carrying medium, as for instance by a typewriting machine and thereupon it must be transferred to a second machine for application of the code designations, the diiculties previously referred to are aggravated with regard to time consumption and personnel.

Where some or all of the recorded data must be reproduced as for instance by manual operation of typewriters on various carrying media in various arrangements to suit particular requirements, the foregoing diniculties would be still further aggravated.

lt is accordingly among the objects of the invention to provide a system by which sequences of data may be recorded upon a suitable medium, while automatically and selectively setting up for subsequent recording in code, so much only of the data as is desired and upon completion of the recording of at least the data that is to be encoded, automatically recording such data in code, all at high speed, with a minimum of personnel, without likelihood of human error, even though checking is dispensed with and by resort to equipment relatively compact in size, the operation of which may be eected manually from a substantially standard typewriter keyboard, without need on the part of the operator manually to handle or transfer the medium from one machine to another or to interpret or even to read data for subsequent recording as code.

Another object is to provide a system by which, in addition to the master record of all data concerned with a particular item, there are automatically prepared one or more additional records for each item, each additional record having selected portions only and in distinctive arrangements of data to suit requirements.

According to the invention, the medium upon which a sequence of data is to be recorded preferably may comprise a substantially rectangular card which, when originally positioned in the master typewriter will be in a predetermined starting position, so that all of the cards on which information is to be recorded will have corresponding items within the same areas or elds on successive cards.

With each movement of the carriage of a typewriter, preferably of conventional electric type, caused by actu.- ation of a typewriter key, the conventional space bar or the carriage return key for example, an impulse will be delivered to a suitable control unit pulsed in timed yrelation with the movement of the typewriter carriage.

Only when the card is in position to receive data to be encoded, will the control unit ready a code storage unit, to be thereupon actuated by impulses from a coding unit that is controlled by actuation of predetermined selected keys only, of the typewriter.

rhe code storage unit will thus set up for subsequent uecording in code, the data transmitted thereto and after at east the data that is to be encoded has been recorded on the card, the storage unit will be actuated from the control unit to deliver impulses at intervals to cause a single code typing member in the typewriter to type at correspending predetermined positions of the card.

The system may include one or more auxiliary or slave typewriters actuated simultaneously with the actua.-y tion of the keys of the master typewriter to type any desired portion of the data recorded by the master type writer, the portions of the data typed by the slave type? `efriter and the position of such data on the card in the slave typewriter being determined by such control unit.

Figs. l0 and 1l illustrate the cards used in the master and slave typewriters respectively, and

Fig. l2 is a chart of the code utilized on the card.

To facilitate understanding of the invention, a general description of one particular embodiment shown in the drawings, especially adapted for use in subscription ful-y filment, will tirst be made followed by the more partie-uf larizcd description under various headings thereafter.

As a purely illustrative example, each of the subscription cards in the electric master typewriter is to be typed illustratively with the number of the salesman, a number representing the geographical location in which the sale was made, the date of expiration of such sub.- scription, and an indication, such for instance as the letter R may be typed after the date if the subscriptionv is a renewal.

The second, third and fourth lines of the subscription card may be typed with the name, street address and town respectively of the subscriber and if a renewal subscription, the previous date of expiration may be typed on the fth line.

After the salesmans number has been typed on the subscription card, a control unit governed by each typing operation will be pulsed, automatically to effect advance or" the typewriter carriage until the position or held on the card at which the geographical location number is to be typed is at type head striking position.

After the month, decade and year numbers Vhave been typed, the control unit will ready a renewal unit. The letter R key to be pressed only for renewal subscriptions, actuates the previously readied renewal unit'` to set suitable circuits in order to permit subsequent er1- coding of the previous expiration date.

After the desired information has beentyped on `line of the subscription card, the control unit will automatically effect actuation of the conventional carriage return mechanism of the master typewriter Yin order to bring the platen in position for typing at the beginning of line 2.

The name, street address and townmay then ibe typed' on lines 2, 3 and 4 respectively, a tabulating key designated Tab Out being manually actuated, after the typing on each line has been completed in order to bring the platen in position for typing at the beginning of the next line.

If the subscription is a renewal, a tabulating key designated Tab In is then manually pressed to effect advance of the typewriter carriage to bring the platen to that position on line 5 determined by the control unit, at which typing of the previous expiration date is to commence.

After such date has been typed, the control unit will effect actuation of the carriage return mechanism of the master typewriter for typing on the card at the beginning of the next, that is the sixth line.

Under control of certain keys of the master typewriter, illustratively the numeral keys, are circuits to energize relays vof a coding unit arranged in permutations and combinations uniquely corresponding to the several keys. The coding unit is connected to a code storage unit having relays which are readied by the control unit when and only whenV the platen is in position for the card thereon to receive data to be encoded. Typing of the geographic location, the expiration date and the previous expiration date of a renewal subscription would thus actuate the previously readied storage unit relays thereby to store solely such data for subsequent release.

Subsequently, the control unit by completing circuits from the actuated relays of the storage unit to a solenoid in the master typewriter, elects the typing of designations desirably in the form of uniform bars within predetermined regions on the card, which regions correspond to the stored code.

The multiplicity of distinct cards thus prepared by the master typewriter may be automatically classified by running them through suitable equipment.

The setting of the control unit may determine both the selection and arrangement of data to be typed by one or more slave typewriters. Thus, each slave typewriter may, according to requirements, serve to type only selected portions of that which is typed by the master typewriter and may so type such selected portions on a greater or lesser number of lines than does the master typewriter. More particularly, the control unit selectively readies solenoids by which type heads of the slave typewriter are operated'under control of the corresponding master typewriter keys. The control unit may also be set to etect actuation of the slave typewriter carriage return mechanism Vupon completion of such typing as is to be elected by the slave typewriter on any one line.

Having thus briefly described the equipment, there will now be described one particular embodiment of the invention under various headings.

Cards (Figs. and I1) In the illustrative embodiment herein shown, the cards are of two distinct types, i. e., subscription cards 11 which are prepared by the master typewriter 21 (Fig. 2) and billing cards 12, for example, which are prepared by one or more slave typewriters 294 (Fig. 3).

As shown in Fig. 10, the subscription card desirably is to vhave data typed thereon in a number of distinct fields on dilerent lines. The rst eld 13 on line l may be for a group of numbers representing a salesman, for example; the second eld 14 for a number representing geographical location; the third iield 15 for the date of expiration of the present subscription and the fourth eld 16 for a letter R if the present subscription is a renewal.

The elds on the second, third and fourth lines may be for the name, street address and town and state respectively and the field on the fifth line for the date of expiration of the previous subscription if the present subscription is a renewal.

A plurality of lines of the subscription card, illustra` tively lines six, seven and nine are designed to receive 4 code designations, preferably in the form of bars corresponding to geographical location and dates respectively.

To this end, line six illustratively has four equal regions, the iirst of which is three type spaces from the beginning of the line with two type spaces desirably intervening between adjacent regions. Each of the lines seven and nine illustratively has twelve equal regions,

the iirst region also being three type spaces from the` beginning of the line and with two spaces intervening between adjacent regions. Y

The code bars on lines 7 and 9 corresponding to date are arranged in three sets of from one to three bars each. The first set of designations may be the code for the month, the second set for the decade and the third set for the year. As shown in chart .110 in Fig. 12, the months of January, February, March and April may be represented by a bar at regions 1, 2, 3 and 4 respectively which are at the fourth, seventh, tenth and thirteenth spaces on the card 11 respectively. The months of May through October may be represented each by two bars respectively at regions 1, 2; 2, 3; 3, 4; 1, 3; 2, 4; and 1, 4. The months of November and December may be represented by three bars respectively at regions 1, 2, 3 and 2, 3, 4. Similarly, the decades from l to l0 and the years l to 10 may be represen-ted by one or two bars at regions 5 to t5 inclusive and 9 to 12 inclusive respectively.

With respect to the code designation in the four regions on line 6 which refer to geographical location, the character 0 may be represented by bars at regions 1, 2, 3 and d; the numbers from l to l0 inclusive by bars in the same position as those related to decades, and the numbers l1 and l2 by bars at regions l, 2, 3 and 2, 3, 4 respectively.

The card 12 which is typed by the slave typewriter has two sections A and B and only section A is to contain typed data. Thus, the card has six lines on which are to be typed respectively the salesmans number, the geographical location, the date of expiration of the subscription, the subscribers name, street address and town and state.

Master typewriter (Fig. 2)

The master typewriter shown in detail in Fig. 2 prepares the cards 11 for use in classification equipment and is manually operated to type the desired data on the subscription card 11 and is automatically operated to code selected portions of the typed data. This typewriter is desirably of conventional electric type such as that sold by Underwood Corporation, which has been modified for use in the present system.

Thus, the typewriter has conventional mechanism at tached thereto (not shown) by means of which the subscription card 11 placed therein may be aligned so that a type head may strike at the first position on line 1 of the card. The typewriter also has the conventional keys K for the letters of the alphabet, the period and comma symbols and the numerals 0 to l2 inclusive, and a plurality of switches 23 operated through the lever transmissions (not shown) from such keys K. As shown in Fig. 2, each of the switches 23 has a ixed contact 24 connected to positive main 25 and a contact arm 26 actuated by the associated key K.

The contact arms associated with the keys K are connected respectively to a plurality of terminals 27 on a terminal strip 28. In the illustrative embodiment shown, the conventional space bar 2t) which controls the carriage spacing mechanism, and the carriage return key 19 which controls the carriage return mechanism are actuated by solenoids 31 and 32, one side of each of which is connected to the positive main 25 and the other sides of which are connected to terminals 33 and 34 respectively on terminal strip 28. The typewriter has an additional type head (not shown) illustratively designed to print a code bar and the key which normally would control such type head is actuated by a solenoid 35, one end of which arcanes is connected to positive main and the other end o f which is connected to terminal 36 on terminal strip25.

@ne side.of the standard motor 3S of the typewriter is connected to one side of the power line P, and the other side of said motor 38 is connected by lead 39 to fixed contact 41 of a relay 42, the contact arm 43 of which is normally spaced from said ixed contact 41 when the coil 44 of said relay is not energized, and connected by lead 45' to the other side of the power line. One side of coil 44 of relay 42 is connected to negative main 46 and the other side of said coil is connected to terminal 47 on terminal strip 28 of the typewriter.

The conventional platen and escapement mechanism or the typewriter is modiiied by the addition of a cam 50 which controls a normally open switch 51, the cam 50 being rotated one complete revolution by motor 3S after each release of a key' K, actuation of the space bar 20 or carriage return to the beginning of a line. Each revolution of cam 50 brings the switch Contact arm 52 which is connected to positive main 25 against fixed contact 53, connected by lead 54 through coil 55 of relay 56 to the negative main 46. The relay 56 desirably has a fixed contact 5S connected to the negative main 46 and a contact arm 59 normally spaced therefrom and connected to terminal 61.

The terminals 27 on terminal strip 28 of the typewriter 21 shown in Fig. 2 associated with the numbers 0 to 12 are connected respectively by lead (Fig. 1) to a plurality of terminals 66 on terminal strip 79 of a coding unit S1 shown in Fig. 5.

Control zmz'z (Fig. 8)

The primary function of the control unit is to discriminate those portions of the data which are to be coded from the remaining portions by regulating the operation or the coding nnit and storage unit and to regulate the recording of the code on the cards. Although any suitable means could be used, illustratively stepping switch means are utilized in the control unit and although a single stepping switch conld be used, in order to provide snlicient contacts, in the illustrative embodiment herein, the control unit desirably comprises a plurality of stepping switches illustrativeiy iive in number designated S-l to 8 5 which may be or" the type 45 switch put out by the Automatic Electric Company of Chicago, Illinois. Each switch ilinstratively has a piurality of banks, at least four in number designated B-1 to B4-, each having a 0 or home contact and 52 additional contacts as well as four ganged wiper arms 5l-1 to W41, each stepping switch eing of the tyoe in which the Wiper arms advance in unison only upon de-energization of the associated coils 231 to 235 respectiveiy. Although the banksof each stepping switch are arranged in an arc, they are illustra'- tively shown in a straight line for facility of description.

The wiper arras FJ-1, idf-2 and 'yV-3 of banks B11, B-Z and 13-3 of each stepping switch are connected to* gether by common main 236 which is connectedto-ter- .minal 237 .and such terminal is connected by leads 225 (Fig. 1) to terminal 226 of section A of the cycling unit Y222 (Fig. 4). The wiper arms W-d (Fig. 8) of each of the stepping switches are connected together by common main 238 which is connected to terminal 232 and by lead 227 (Fig. 1) to terminal 223 of section A oi' the cycling unit 222.

One end of each of the coils 23l to 235 of stepping switches S-l to S-5 (Fig. 8) is connected to common main 241 and to positive main 25. Each coil controls three contact arms 243, 24d and 245, the 2153 normal y engaging fixed contact 246, arm 24d normally being spaced from tixed contact 247 and the arm 24.15 normally engaging Xed Contact 248 and being spaced from lined contact 249. The xed contact 247 of each of the coils 231i to 235 connected to an associated terminal 2.5i t. tively. Each arm 244 is connected to the associated iiXed Contact 246; the arm 243 is connected to the other side of the associated coil 231 to 235 and by lead 257 to fixed Contact 249.

Slave typewriter (Fig. 3)

If desired, one or more slave typewriters may be used in conjunction with the equipment above described. The slave typewriter may also be a standard electric typewriter such as that sold by Underwood Corporation, modified as indicated for use in the system and provided with card aligning mechanism similar to that on the master typewriter and modified for use in the present system.

To this end, as shown in Fig. 3, each of the keys K of the slave typewriter 294 has a solenoid 433 associated therewith, and the carriage return key 482 has a solenoid 484 associated therewith, the terminals e395 and 496 of which are connected respectively to positive main 25 and to terminal 297 on terminal strip 439. The core of each of the solenoids has a plunger rod 485 ailixed thereto to actuate the associated key.

One of the terminals 486 of each of the solenoids 483 is connected by common main 487 to terminal 293 on terminal strip 439. The other terminal 493 of each of the solenoids is connected to an associated terminal 492 on terminal strip 439 and the terminals 491 are connected by leads 492 (Fig. 1) to the respective terminals 27 on the typewriter shown in Fig. 2 associated with the corresponding letter, numeral or symbol.

Operation In the operation of the equipment, cards il, i2 are positioned in the master typewriter 2l and the slave typewriter 294 respectively, said cards desirably being aligned at the same position with respect to the type heads by the conventional mechanism attached to the machine so that a type head actuated may strike at the rst position on line 1 of each card.

The Set button 336 of section A of cycling unit 222 (Fig. 4), is pressed to ready the equipment for the subsequent manual typing operation. As a result, a circuit will be completed from negative main 46, through closed contacts 385, 384, lead 333, contacts 337, 333, coil 339 of relay 375, lead 416, closed contacts 405, 466 of relay 399, lead 417, closed contacts 43.3, 421 of relay 419 to positive main 25. Thus, the coil 339 of relay 375 will be energized and a holding circuit provided from negative main 46 through closed contacts 377, 33S. In addition, contacts 376, 37S will open and contacts 3%, 393 and 392, 394 will close. Closing of contacts 391, 393

Vwill connect terminal 395 to positive main 25 and through lead 396 (Fig. l) and terminal 47 of the typewriter 2li (Fig. 2), the coil 44 oi relay d2 will be energized, closing its contacts 41, 43 to energize motor 33 thereby readying the typewriter 21 for operation.

The initial pressing of the Set button 336 (Fig. 4) will also momentarily connect negative main 46 through contacts 335, 334, lead 383, contacts 376, 378 to terminal 379 and thence through lead 381 (Fig. 1) to terminal 261 of control unit i79 (Fig. 8) and through the series connected, closed contacts 245, 24S of stepping switches S-l to S-5, lead 253 to one side of the coil 231 of stepping switch S-l and through lead 241 to positive main 2S.

Energization of coil 23T. (Fig. 8) will open the associated normally closed contacts 243, 246. As terminal 379 (Fig. 4) is only momentarily connected to negative main 46, coil 231 will only he momentarily energized and upon deenergization, contacts 243, 246 will immedlately close. Upon the de-energization of coil 231, the four ganged wiper arms W-i to ft/ 4 of stepping switch S- will move from or home position to engage the associated contacts 1 of banks B-i to E-4. The contacts 244, 247 will also close and the contact arm 245 will engage iixed contact 249. The contacts 244, 247 and 245, 249 will remain closed through the entire cycle of 12 operation of the associated stepping switch until its wiper arms return to home position, through a mechanical spring action (not shown) which is a conventional part of the stepping switch.

After the Set button 386 is pressed, and the equipment is ready for operation, data may be typed on the card 11 in the master typewriter 2i. As illustratively set up, information typed in the iirst sir; positions on the iirst line of the card 11 (Fig. 1G) edects no control action by the control unit. Assuming that a key K associated with any one of the numbers from O through l2 is pressed to type'such number on the subscription card il, after the key is released and the key arm moves back to normal position, the carriage will move one space and the conventional escapement mechanism of the typewriter will rotate the cam 5t) one revolution momentarily to close the contacts 52, 53 of switch 5l. When contacts 52, 53 are closed, a circuit will be completed through such contacts from positive main 25 through lead 54 and coil 55 of relay 56 to negative main 46. Energization of relay 56 will close its contacts 5S, 59 momentarily to connect the negative main 46 to terminal 6l.

As terminal 61 of typewriter 2i is connected by lead 262 (Fig. 1) to terminal 261 of control unit 179, as previously described, coil 232i (Fig. 8) will be energized but this time through contacts 245, 249 which have previously been closed when the Set button 386 was pressed. Energization of coil 231 will have no eicct on contacts 244, 247 or 245, 249 but Will momentarily open contacts 243, 246. Upon de-energization of coil 231i when relay 56 (Fig. 2) is no longer energized, the wiper amis W-l to 2V-4 of stepping switch S-i will move to engage the contacts 2 of banks B-1 to B4.

As the keys K of typewriter 21 associated with tive additional numbers are pressed and released or if the space bar 20 of the typewriter 2l is pressed and released, the operation above described will be repeated and the wiper arms W-l to W-4 of stepping switch S-1 will advance from contact to contact of banks B-l to B-4.

The operation of any of the keys K of the typewriter Z1 (Fig. 2) will also close the associated switch 23 to complete a circuit from positive main 25 through such switch to the associated terminal 27. Each time such terminal 27 is connected to positive main 25,V a circuit will be completed through lead 492 (Fig. l) to terminal 491 of slave typewriter 294 (Fig. 3) which is connected to one side 490 of a solenoid 483 which controls the corresponding key of the slave typewriter.

As the wiper arms W-l to W-3 of stepping switch S-l which have been connected to negative main 46, are advanced, and as wiper arm W-S successively engages contacts 1 to 6 of bank B-3 of said stepping switch S4, which are connected to terminal 291i (Fig. 8), the negative main 46 will be connected from said terminal 291i through lead 292 (Fig. l) to terminal 293 of the slave typewriter 294 (Fig. 3) which is connected to the other sides of all of the solenoids 483.

Consequently, if any of the keys K representing the numbers 0 through 12 are pressed on the master typewriter to type such number on line l of the subscription card 11, the related keys in the slave typewriter 294 will be actuated at the same time to type the corresponding numbers on line 1 of the card l2 in the slave typewriter.

As the terminals 27 associated with the keys K representing the numbers 0 through 12 are connected to positive main 25, a circuit will also be completed from such terminals 27 through leads 65 (Fig. l) to the associated terminals 66 of coding uni-t ii (Fig. 5) and thence through the coil 82 of the associated relay R-t) to R-lZ to negative main 46. Energization of the relays in the coding unit will close the associated contacts 83, tlf?, so that one or more of the terminals 91 to 94 will be cor1- nected to negative main 46. Consequently, the corresponding terminals 97 to M9 of the storage unit 192 1.3 Y (Figs. 6, 7) will VIbe connected to the negative main 46. As none of the terminals 166-172 of the lstorage unit 162 has as yet 'been connected to any potential, none of the coils of the banks M-l to M-7 of the storage unit 162 will be energized at this time.

When the wiper arm W-1 of stepping switch S-1 engages contact 7 of bank B-1, a circuit will be completed from negative main 46 through wiper arm W-l to terminal 276 and thence 'through lead 277 (Fig. l) to terminal 33 `of typewriter 21 to energize space bar solenoid 31 (Fig. 2) to ladvance the carriage of typewriter 21 one space and at the same time rotate cam 50.

Rotation vof cam 56 will again cause the ganged wiper arms W-l to W-4 of stepping switch S- to be advanced one Contact as previously described to engage contact 8. As shown in Fig. 8, contacts 7 to 12 of bank B-1 `of stepping switch S-1 are connected to terminal 276 and hence the carriage of typewriter 21 Will automatically be advanced step by step as above described until the wiper arms W-l to W-4 engage contacts 13 of stepping switch SP1 at which time the striking position of the type heads of typewriter 21 will be aligned with type space 13 on card 11.

When the wiper arm W-S of stepping switch S-1 engaged contact 8 of bank B-S, the negative main 46 was connected through wiper arm W-3, contact to terminal 295 and thence through lead 296 (Fig. l) to terminal 297 ot the slave typewriter 294 (Fig. 3) to energize solenoid 484 controlling the carriage return key 432. As a result, the platen rof the slave typewriter will be rotated one space t-o the second line and the carriage of the slave typewriter will be moved back to the beginning of such Vsecond line so that the striking position of the type keys will be aligned with the i'lrst position on such line.

As the thirteenth contact of bank B-1 of stepping switch S1 is connected to terminal 175, the negative main 46 will be connected through wiper arm W-l to terminal 175 and through lead 174 (Fig. l) to terminal 166 of storage unit 162 (Fig. 6). As a result, the coil 122 ot' relay 107 of memory bank M-1 will be energized to close its four pairs of contacts 114, 113; 115, 119; 116, 120 and 117, 121, the relay 167 remaining energized only as long as the wiper arm 2V-1 of stepping switch S1 is engaging contact 13.

The thirteenth position on the card 11 represents a field 14 at which a number indicating the geographical location or source of a subscription, for example, is to be placed. Assuming that the number is 4, the corresponding key K of typewriter 21 (Fig. 2) is nov.I pressed to type such number at the thirteenth type space on line 1 of card 11.

Referring to Fig. 2, this willclose the associated switch 23 connecting the related terminal 27 to positive main 25. As a result, through lead 65 the corresponding terminal 66 of the coding unit 31 (Fig. 5) associated with relay R-4 related to the number 4 will also be connected to positive main 25 to complete a circuit through the coil 82 of the relay to negative main 46. 1n addition, through lead 492 (Fig. l) and terminal 491, one side of the solenoid 483 of the slave typewriter associated with number 4 Will be connected to positive main 25.

.By the connection of terminal 66 of the coding uint 31 (Fig. to positive main 25,-relay R-4 will be energized to close its associated pair or contacts 83, 84 which will connect terminal 91 to negative main 46 and through the associated lead 96 (Fig. l), terminal 97 of the storage unit 162 (Fig. 6) will also be connected to negative mainf46.

As a result, a circuit will be completed (Figs. 6, 7) from negative main 46 through main 12S, lead 127, contacts 126, 124, coilV 125 ofv relay 103 of bank M-1, leads 129, 132, contacts 117, 121 of relay 1537 which were closed when Acontact 13 of bank B-1 of stepping switch 'S-l was engaged by wiper arm W-L lead 142, main 143 14 to terminal 144 which is connected by lead 216 (Fig. l) toterminal 221 of stition A of unit 222 (Fig. 4) and thence through closed contacts 418, 421 of relay 419 vto positive main 25.

Coil of relay 193 o f bank M-1 will thus 'oe energized and a holding circuit is provided for such rela;I through contact arm 111 connected to negative main 46 and contact 124 connected to coil 125; contacts 112, 131 will close and contact arm 113 will engage contact 162.

As wiper arm W-3 of stepping switch 5 1 (Fig. 8) is engaging Contact 13 ot bank B-ls, terminal 291 .o'r` stepping switch S-1 will be connected to negative main 46 and through lead 292 (Fig. 1) to terminal 293 connected to terminal 48.6 of all or the solenoids 483 or slave typewriter 294 (Fig. 3). As the other side of the solenoid 433 associated with key number 4 has been connected to positive main 25, such solenoid will be energized and the key associated with number 4 of the slave typewriter will be actuated to type number .47 at the rst position yon line 2 of the card 12 in the slave typewriter as shown in Fig. ll. y

When key K associated with the number 4 of the master typewriter 21 is released, can 5% will again be rotated momentarily to close switch 51 thereby energizing relay 56 to connect terminal 61 to negative main 46, and through lead 262 and terminal 261, the coil 231 of stepping `switch S1 will momentarily be energized to move its wiper arms W-1 to iV-4 to engage contacts 14. As a result, coil 122 of relay 167 of bank ivi-1 of the storage unit 1132 .will be de-energized, but due to the holding circuit -for relay 1613 of such bank, relay 103 will remain energized 'to retain the number 4.

As the wiper arm W-'l of the stepping switch S- 1 is now engaging the contact 14, which is connected to terminal 276, the negative main 46 will be connected through the wiper arm W-1 and contact 14 to terminal 276 and by lead 277 (Fig.k l) to terminal 33 of the typewriter 21 to energize solenoid 31 to actuate the space bar. As a result, the carriage of the typewriter 21 will move one space to position 15 of the card 11 and cam 59 will again rotate to cause a negative pulse to be delivered by relay 56 Vas previously described, to terminal 261 of the stepping switch S-1. Consequently, coil 231 of stepping switch S-1 will again momentarily be energized so that upon de-energization of said coil, wiper arms 'VV-1 to W-4 will move to engage contacts 15. As contacts 14 to 18 of bank B-1 are connected to terminal 276, the stepping operation will automatically be repeated and wiper arms W-1 to W-4 will step to engage contacts 19 at which time the carriage ot typewriter 21 will have advanced so that when a key is pressed the type head will strike the nineteenth position on row 1 of the card 11 in the master typewriter.

When wiper arm W 3 of stepping switch S-1 engages contact 14, terminal 295 will be connected to negative main 46 as will terminal 297 of slave typewriter 294 through lead 2% (Fig. l). Consequently, as vpreviously described, solenoid 484 will be actuated to operate the carriage return key 482 to causethe platen of the slave typewriter to rotate the card to line 3 and the carriage to be'moved to the beginning of su-ch line.

As contact 19 ot bank 3 1 of stepping switch S-l is connected to terminal 176 (Fig. 8), the negative main 46 will be connected through the associated lead '174 (-Fig. l) to terminal 167 of storage unit 102 to energize coil 122 .of relay 167 of vbank M-Z and close its lfour Apairs of contacts. At this time a date can be typed on the card 11 `in the master typewriter such as, for example, June 52 represented by the numerals 6 5 2.

' The key K associated with the number 6 is pressed to type the number f6 Yat the nineteenth position on line 1 of card 11 and to close the associated switch Y2 3-thereby connecting the 'associated terminal v27 to positive main :2.5. AS previously described, this `will .connect positive main 425 through lead 65 to the terminal 66 associated with relay R-6 of the coding unit 81 and through lead 492 to the terminal 491 of the slave typewriter 294 associated with the solenoid 483 controlling the number H6!) Energization of relay R-6 (Fig. 5) will close the two pair of contacts 83, S4, to connect mains 86, 87 and terminals 92, 93 to negative main 46 and through the associated leads 96 the terminals 9S and 99 (Fig. l) of the storage unit 192 (Fig. 6) will be connected to negative main 46. As a result, relays 104, 165 of bank M-2 related to the number "6 will be energized, as previously described with respect to relay 102 of bank M-1, and by reason of the holding circuits for such relays through contacts 111, 124 they will remain energized with their contacts 112, 131 and 113, 162 in engagement.

When terminal 491 of the slave typewriter associated with the solenoid 433 controlling the number 6 key is connected to positive main 25, as wiper arm W-3 of stepping switch 3 1 is engaging contact 19, through terminal 291 and lead 292, the terminal 293 of the slave typewriter connected to the terminals 486 of all of the solenoids 433 will be connected to negative main 46. The solenoid 483 controlling the key associated with number "6 will be actuated to type such number at the iirst position on row 3 of card 12 in the slave typewriter.

When the key K (Fig. 2) for number "6 is released, the carriage will move one space to position 20 on the card 11 and cam 5t) will rotate as previously described to cause a negative pulse to be delivered from terminal 61 through lead 262 to terminal 261 of the control unit 179 to advance the wiper arms of stepping switch S-1 to engage contacts 2G. The contact 29 of bank B-l is connected to terminal 276 and through lead 277, terminal 33 of the typewriter 21 will be connected to negative main 46 to energize solenoid 31 to advance the carriage one space to position 21 and cam 5f! will again cause a pulse to be delivered to terminal 261 of the stepping switch S-1 to advance its wiper arms to engage conta-cts 21. Consequently, the negative main will be connected from contact 21 of bank B-1 to terminal 177 and thence through the associated lead 174 to terminal 168 of the storage unit to energize relay 107 of bank M-3 to close its four pairs of contacts.

The key K of typewriter 21 associated with. the num(- ber is then pressed to type the number 5 at position 21 lon line 1 and by reason of the closing of switch 23 as previously described, the solenoid 483 of the slave typewriter associated with the number 5 will be energized to type such number at the second position on row 3 of the card 12 and the relay R-S of coding unit S1 will be energized to close its two pairs of contacts and connect terminal 93 and 94 to negative main 46.

As a result, the terminals 99 and 104) of the memory unit will also be so connected through the associated leads 96 and the relays 195, 196 of bank M-3 related to number 5 will be energized and retained by the associated holding circuit with contacts 112, 131 -and 113,V 162 in engagement. V

Release of the key K associated with number "5 will cause the carriage `of the master typewriter to move one space to position 22 on card 11 and cam 50 will again rotate to lcause a negative pulse to be delivered through lead 262 to terminal 261 of stepping switch S-l to move its wiper arms to engage contacts 22. As a result, terminal 178 will beconnected to negative main 46 and through lead 174, terminal 169 of storage unit 102 will also be connected to negative main 46 thereby energizing relay 107 of memory bank M-4 to close its contacts.

The key K of typewriter 21 associated with the number 2 is then pressed toV type such number at position 22 of the card 11 andrby reason of the Vclosing of switch 23 as previously described, the relay R-2 of coding'unit 81 will be energized to close its pair of contactse83, Y84 `and connect terminal `93 to negativemain 46 and the 16 solenoid 483 of the slave typewriter associated with the number "2 will be energized to type such number at the third position online 3 of card 12.

When terminal 93 of the coding unit is connected to negative main 46, the terminal 99 -of the storage unit will also be so connected through theassociated lead 96 and the relay of bank M-4 related to the number "2 will be energized and retained by the associatedrholding circuit with conta- cts 112, 131 and 113, 162 in engagement.

Release of key K associated with number 2 will cause the carriage of the master typewriter to move one space to position 23 on the card 1l and cam 5t) will again rotate to cause a negative pulse to be delivered through lead 262 to terminal 261 of stepping switch S-1 to move its wiper arms to engage contacts 23. As result,V terminal 276 of the control unit 179 will be connected to negative main 46 and through lead 277, terminal 33 of the typewriter 21 will also be connected to negative main 46 to energize solenoid 31 to advance the carriage one space to position 24 on the card 11. Cam 5t! will again cause a pulse to be delivered to terminal 261 of control unit 179 to advance the wiper arms of stepping switch 8 1 to engage contacts 24. Consequently, the negative main will be connected from contact 24 of bank B-1 to terminal 273 and thence through lead 279 (Fig. l) to terminal 234i of renewal unit 184 (Fig. 9) which is connected to one side of coil 366 of relay 351.

lf the subscriber for whom the cards are being prepared had a previous subscription, it may be desired to record the fact that the present subscription is a renewal and aiso to record the date of expiration of the previous subscription.

For this purpose, that key K which is associated with the letter R on the master typewriter 21 is pressed, and will type such letter at the twenty-fourth position on line 1 of card 11. This results in closing the corresponding switch 23 and the terminal 27 associated with the letter R will accordingly be connected to positive main 25 and such positive :main through leads 492 and 36S (Fig. l) wil be connected to the terminals 491 and 367 of the slave typewriter 294 and the renewal unit 184 respectively. As terminals 486 of all the solenoids 483 ofthe slave typewriter are connected to negative main 46 from contact 24 of bank B-3 of stepping switch S-1 through terminal 291, lead 292 and terminal 293 (Fig. 3) and as the terminal 491 of the solenoid 483 which is associated with the letter R is connected to positive main'25 by reason of the pressing of the key K of the master typewriter associated with therletter R, the letter R will be typed on the card 12 at the fourth position-immediately after the date 6 52.

As one side of coil 366 of relay 351 of renewal unit 184 is connected to negative main 46 from contact 24 of bank B-1 of stepping switch S-1 as previously described, when terminal 367 is connected to positive main 25, relay 351 will be energized to close its contacts 352, 353; 352' 353'; 354, 355; 356, 357; 358, 359; 360, 361; and to open its contacts 362, 363 and 364, 365. Closed contacts 352, 353 alord a holding circuit for relay 351 from positive main 25 and closed contacts 352', 353 atord a holding circuit for relay 351 from negative main 46 (Fig. 4-A), closed contacts 423, 424 of relay 419, terminal 425, lead 426 (Fig. l) to terminal 280' (Fig. 9). I

When the second date is now typed it will be coded as a result of the energization of relay 351 in the manner hereinafter to be described.

Upon release of the key K associated with the letter iR, the carriage will move to position 25 and the cam 5t) will rotate as previously described to deliver a negative pulse to terminal 261 of control unit 179 momentarily to energize coil 231 of stepping switch S-1 so that its wiper arms will move to engage contacts 25.

Y If the present subscription is an original subscription, instead of pressing the letter R key, the space bar of 17, the master typewriter is pressedandthe ar'riagewill move onev space' with resultant rotation of cam .56 s that a negative pulse wilhle delivered tov coil 231 of stepping switch S-l also to i'rove its wiper arms to engage contacts 25.

In the illustrative embodiment herei`n only 24 spaces on line 1 of the card 11 in the master typewriter are utilized and hence when the wiper arm W71 of stepping switch S-l engages contact 25 on bank B-, terminal 281 will s e connected to negative main 46. As a result, through lead 232, terminal 34 of typewriter 21 will also be connected to negative main 46 ,and the associated solenoid 32 will be energized to operate the conventional carriage return mechanism of the typewriter 2l. Thus, the platen will be rotated one line and the carriage will be returned so that the Ytype head neXt to be actuated will strike the rst position on line 2 of card l1. Cam Sil will also rotate momentarily to energize, coil. 231 of stepping switch S-l to advance its wiper arms to engage contacts 26.

When wiper arm W-3 engages contact 25 of bank` B-3 or stepping switch S-l, terminal 295 will be connected to negative main 46 and through lead 296 (Fig. l), terminal 297 will be connected to negative main 46 to energize carriage return solenoid 434V of the slave typewriter to rotate its platen one line to line 4 and move its carriage so that the type head next to be actuated will strike the tirst position on such line.

A name may now be typed in conventional manner on linevZnof card l1 in the master typewriter. As the keys K associated with the letters of the name are pressed, the corresponding switches 23 will be closed to connect the associated terminals 27 to positive main 25. Through the associated leads 492, terminals 491 of the slave typewriter related to the letters will be connected to positive main' 25 and as previously described, the respective sole# noids 483 will be energized to type the letters on the card 12.

Assuming that the wiper arms W-l to W-4, as the keys K are actuated, have reached contacts 36 and no further letters or the name remain to be typed, the carriage or" the master typewriter may readily be moved so that t, e type keys will strike at the `iirst position on the third line of card 11 and the platen rotated to line 3 by merely pressing the tabulating button 444 designated Tabf Out in section B or" cycling unit .222 (Fig. v4). When this button is pressed, the coil 438 of relay 431will be energized through closed contacts 441, 443 of switch 442 and the closed contacts 446, 44S of relay 445 and kcontacts 432, 435 or relay 431 will close to provide a holding circuit for such relay.

Contacts 433, 436 and 434, 437 will also be closed by energization or coil'438. As a result, a circuit will'be completed from wiper arm W-l of stepping switch S-l connected to negative main 46 and which is presently engaging contact 3e, terminal 283, lead 234V (Fig. l), terminal 235 section B or" cycling unit 222,A closed contacts 433, 436, terminal 3%, lead 299 to terminal 293 of bank B-4 of stepping switch S41 (Fig. 8)'andthence by lead 293 to terminal 251 of stepping switch S-l. As contacts 243, 246 and 244, 247 are closed, thecoil 231 will be energized opening only contacts 243, 246, to de-` energize coil 231i causing wiper arms W -1 to 4'yV-4 to move to engage contacts 37 and the contacts 243, 246 will again close when contact 37 of bank B-1 is again engaged. The above cycle will be repeatedandsuch'op'- eration will continue rapidly, without movement .of the carriage of the typewriter 21, until thevwiper armslWv-l to vll-3 which are connected to Vnegative main '46 and wiper armV Sil-4: engage contacts Sii. I

As contact 5l) on bank B-'lof steppin'gswitch' S41 is connected to terminal 281VA and throughl lead 2,8,2`to termin'al34 ofjtypewriter 21 v(Fig'. `2), the'carriage return solenoid will ,be`energiz`ed'to` rotateth'e' plateri'pfthe rriasitr"z typewriter to line 3"an"d rnve the carriage yso'v that the type heads mayvstrike the. rst positiononsuch When the carriage moves, cam Sllwill be rotated todo; liver a negative pulse to coil 231 of stepping switch S-l to advance its wiper arms to engage contacts 51.. l l When wiper arm W-2 of steppingswitch Srl engags, Contact 5t?, terminal 286 will be connected tolnegativ'e main 46 and through lead 283 (Fig. l), terminal 289.gif section B of. unit 222 will be so connected. Y.As a result, coil 449 of yrelay 445 will be energized to open itscon; tacts 446, 443 to break the holding circuit for the coil 438 of relay 431. Thus, the relay 431 will be dre-energizedto open its contacts to ready the relay for the next Tab Out operation. i When wiper. arm IV-3 of stepping switch S-l engages contact 5t) of Bank B-3, terminal 2,95 Will be connected to negative main 46 and through lead 296 (Fig. l)Hte r m i-, ral 297 of the slave typewriter will also beso connected to energize carriage return solenoid 484 :torotatfeethe platen of the slave typewriter to-line 5 and move the carriage to the beginning of such line. l l

The address may then be typed online 3 of cartill. Although the address may containnumbers which actuate the relays of :coding Vunit 81, as none of the coils 12 2.:of relays 197 of the storage unit are energized at this time, the action of the coding unit will have no Veffect to actuate any of the relays of the memory banks. When the V,key K representing the rst character of the address is pressed, the corresponding character will be typed at the rstposi; tion Aon line 3 of card 11 inthe master typewriter and, lt the first position on line 5 of card 1,2 in the slave type? writer as previouslydescribed. After the key K lis rey. leased and the carriage of the mastergtypewriter moves one space, due to the rotation of cam 50, coil 231Avwiullbjeenergized to advance the wiper arms to engage contacts 52. At this position, wiper arm W-Zconnects negative main 46 to yterminal 287 and through lead 287 ,terminl 263 of stepping switch S4-2 is connectedto negative. main 4.6. As a result, coil 2.32will be energized to open its normally closed contacts .243, 246. Y .l After the second character of the address, is typed the wiper arms Vof stepping switch S-1 willl move to 0.or., home position. In addition, through the conventionalY mechanical actionV of said switch, contacts l244, V247l and 245, 2.49 will open and contact 245 will. engage Contact 248. As terminal 287 associated with contact 5,2 of bank, -Z is no longer connected tonegative main 46, coil 232 of stepping switch S-Z is de-energized so that its wiper, arms move to engage contacts 1 of banks B-l to B-4 and contacts 243, 246 open, contacts 244, 247v close vand, con-A tact 245 moves away from. contact 248 toengage contact 249, breaking the circuit from terminal 261 throughlead. 257 to coil 231 and connecting terminal 261,- throughS closed contacts 245, 24S of switch S-l, closed contacts. 245, 249 of stepping switch S-2 to one side of its .coil 232', the other side of which is connected to positive main j x; ...5 As additional keys ot' the master typewriterzfal, pressed to type the street address, the wiper armsvlofv, stepping switch S-2 vwill advance fromvthevrst con-tact.

Assuming that the street address has but eight characters,

i. e., l0 Jane St. with the name Jane being separated` from l0 and SL by a single space, as such. characters are typed on the cards, the wiper arms of stepping switch S42 will be advanced as previously described to engage contacts 9.

At this time, the platen of the master typewriter m/ay' rotated one line to line 4 and the carriage moved towthe Tab Out button 444 shown in section B of unit 222.Vv This will cause the relay 431 to be energized and held by'- closed contacts 432, 435. The contacts .i34,.437` will also close to complete a circuit from negative. main 46 thpoughf the wiper arm. W-1 of bank- B-l of stepping switch tterminal Sill and by lead 302m; terminal @lor-,segg tion B of unit 222 through closed contacts 434, 437 to first position on the fourth line by merely pressing the terminal 307 and by lead 306 to terminal 3050i bank B-4 of stepping switch S-2 and thence by lead 305 to terminal 252 'of stepping switch S-2. As contacts 243, 246 and 244,247 are closed, the coil 232 will` be energized opening contacts 243, 246 to de-energize coil 232, causing wiper arms W-1 to W-4 to move to engage contacts and the contacts 243, 246 will again close when contact 10 of bank B-l is engaged. The above cycle will ybe repeated and such operation will continue rapidly until the wiper arms W-1 to W-4 engage contacts 23.

When the wiper arm W-1 of bank B- of stepping switch S-2 is engaging contact 23, through terminal 281, lead 282 and terminal 34, the carriage return solenoid 32 will be connected to negative main 46, thereby rotating theV platen of the master typewriter to the fourth line and moving its carriage to the iirst position on such line to advance wiper arms W-l to W-4 of stepping switch S-2 to engage contacts 24.

Y When wiper arm W-Z is engaging contact 23 of bank B-2 of stepping switch S-2, terminal 286 will be connected to negative main 46 and through lead 288, terminal 289 of section B of unit 222 will be so connected. As a result, coil 449 of relay 445 will be energized to open its contacts 446, 448 to break the holding circuit for the coil 438 of relay 431. Thus the relay 431 will be deenergized to open its contacts to ready the relay for the next Tab Out operation.

When wiper arm W3 engages Contact 23 of bank B-3 of stepping switch S-2, terminal 295 will be connected to negative main 46 and through lead 296 (Fig. l), terminal 297 Vof the slave typewriter will also be so connected to energize carriage return solenoid 484 to rotate the platen of the'slave typewriterv to line 6 and move the carriage to the beginning of such line.

The town and state, for example, may then be typed on the fourth line of the card 11in the master typewriter and the sixth line of the card 12 in the slave typewriter. With each release of the type key K and rotation of the cam 50, the wiper arms of the stepping switch S-2 will advance fromY the twenty-fourth position. After the town and state have been typed, and the wiper arms of stepping switch S-2Y are engaging contacts 34, for example, the Tab Out button 444 may again be pressed to connect the negative main 46 through terminal 381, lead 302, terminal 303 of section B of unit 222, closed contacts 434, r437, terminal 307, lead 306 to terminal 305 of bank 4 of stepping switch S-2 and thence by lead 305 to terminal'252 of stepping switch S-2, As previously described, coil 232 will intermittently be energized to step its wiper arms until they engage contacts 48. l

When the wiper arm W-1 of stepping switch S-Z is engaging Contact 48, negative main 46 will be connected to terminal 281 and through lead 282 to terminal 34 of typewriter 21 toenergize the carriage return solenoid thereby rotating the platen of the master typewriter to the lifth line and returning the carriage to the lirst position on line five. VSuch movement of the carriage as previously described will cause the wiper arms W-1 to W-4 of stepping switch S-2 to advance to engage contacts 49.

When wiper arm W42 is engaging contact 4S of bank B-2, terminal 286 will be connected to negative main 46 and through lead 288, terminal 289 of section B of unit 222 will be so connected. As a result, coil 449 of relay 445 will be energized to open its contacts 446, 448 to break the holding circuit for the coil 438 of relay 431. Thus the relay 431 will be de-energized to open its contacts to ready the relay for the next Tab Gut operation.

When wiper arm W-3 engages contact 48 of bank B-3, terminal 295 will be connected to negative main 46 and through lead 296 (Fig. l), terminal 297 of the slave typewriter will also be so connected to energize carriage return solenoid 484 to rotate the platen of the slave typewriter to line seven and move the carriage to the beginning of such line.

The tirst few spaces on line 5 of card 11 may either.

When wiper arm W-2 engages contact 52 of bank B-2 of stepping switch S-Z, the terminal 384 will be connected to negative main 46 and through lead 304', termin-al 269 of stepping switch S-3 will also be connected to negative main 46. As a result, the coil 233 will be energized to open its normally closed contacts 243, 246.

With the wiper arms W-l to W-4 of stepping switch S-2 engaging contacts 52, if a key K or the space bar 28 should be pressed, the rotation of cam 50 will momentarily energize coil 232 to move its wiper arms to 0 or home position. inl addition, contacts 244, 247 and 245, 249 of stepping switch S-2 will open and contact 245 will engage Contact 248, the movement of arm 245 away from contact 249 breaking the circuit to coil 232. Upon movement of wiper arm VV-2 away from contact 52, the negative connection to terminal 269 of coil 233 will be broken and coil 233 will be tie-energized to move wiper arms W-1 and W-4 of stepping switch S-3 from position 0 to position l and vsimultaneously closing contacts 244, 247 and 245, 249.

At this time, if no further information is to be .typed at the beginning of the fifth line, the Tab In button 462 of Section Cof unit 222 may be pressed. This will energize coil 456 of relay 451 providing a holding circuit therefor through its closed contacts 452, 454. Closing of contacts 453, 455, will connect negative mainV 46 through the wiper arm W-l engaging contact 1 of bank B-1 of stepping switch S-3 to terminal 311 and through lead 311', terminal 313 of section C of unit 222, closed contacts 455, 453, terminal 465, leads 466 and 218 to terminal 33 of typewriter 21 thereby actuating space bar solenoid 31 to move the carriage one space. Such movement of the carriage will cause the wiper arms W-l to W-4 of stepping switch S-3 to advance to engage the second contacts. As the solenoid 31 will be de-energized with each movement of the wiper arms, this operation will continue until the wiper arms engage contacts 14 or" stepping switch S3 at which time the carriage will have been advanced so that the type head next actuated will strike at position 18 on line 5 of card 11. With the wiper arm W-1 engaging contact 14, it will be connected to terminal 314 and through the associated lead 317 to terminal 318 of renewal unit 184. As the contacts 356, 357 of unit 184 are closed, as previously described, due to the previous pressing of the R key, terminal 181 will be connected to negative main 46 as will terminal 170 of storage unit 102 (Fig. 7) through lead 180. This will energize relay 107 of bank M-S to close its four pairs of contacts.

At the same time wiper arm W-2 of stepping switch S-3 will connect the negative main 46 to terminal 322 and through lead 322' (Fig. l) to terminal 324 of section C of unit 222 to energize relay 468 to break the circuit to the Tab In relay 451, opening its contacts and readying the relay for the next Tab in operation.

When wiper arm W-3 of stepping switch S-3 engages contact 14, terminal V295 will be connected` to negative main 46 to energize carriage return solenoid 484 of slave typewriter 294 thereby rotating its platen to line 7 and moving the carriage to the first position on such line.

A second date can now be typed on card 11 in the master typewriter, i. e., say September lrrepresented by the numerals 9 5l.

To this end, the key K associated with the numeral "9 on the typewriter 21 is pressed to type the numeral 9 at position 18 on line 5 and to close the associated switch 23. Although the terminal 491 of the slave typewriter associated with numeral "9 will be connected to positive main 25, as previously described, the associated solenoid 483 will not be energized to type such number, as the contacts after contact 14 on bank B-3 of stepping switch S3 are open and do not connect terminal 293 of the slave typewriter to negative main 46.

The closing of switch 23 of typewriter 21 will, however, energize coil S2 of relay R-9 of coding unit S4, as previously described, to close its two pairs of contacts 83, 84 and connect terminals 91 and 93 to nerative main 46. Through the associated leads 96, terminals 97 and 99 of storage unit 102 (Fig. 7) will be connected to negative main 46. As a result, relays 193 and 105 of bank M-S related to number 9 will be energized and held through closed contacts 111, 124; contacts 112, 131 will close and arm 113 will engage contact 162. After the key K related to number 9 is released, the carriage will move to position 19 and the wiper arms of stepping switch S-3 will advance to engage its contacts 15.

Thus, negative main 46 will be connected through wiper arms 'VV-1 to terminal 276 and through lead 277, to terminal 33 of typewriter 21 to energize the space bar solenoid 31, thereby moving the carriage one space to position 2@ and advancing the wiper arms of stepping switch S-3 to engage contacts 16.

As a result, the negative main 46 will be connected to terminal 315 and through the associated lead 317 to terminal 319 of renewal unit 184, through closed contacts 35S, 359 to terminal 132 and by lead 182 to terminal 171 of storage unit 192 to energize relay 107 of memory bank Ivi-6 to close its four pairs of contacts.

The key it; related to number 5 of theV typewriter 21-` isthen pressed to type num'oer 5 at position 20 on line 5 and to close the associated switch 23 to energize' rel/ay'R-S of the coding unit S1 to close its two pairs of contacts S3, 84 thereby connecting terminals' 93, 94 to negative main do. This will connect terminals 99, 100 ofstorage unit 1112 to negative main 46 to energize relays 165, 196 of bank lvl-6 to close their contacts 112, 131 and to move arms 113Ainto engagement with contact 162, the relays being held by the closing of contacts 111, 124.

Upon release of the number 5 key and movement of the carriage to position 21 the wiper arms of stepping switch S-3 will move to engage contacts 17.

When this occurs the negativeL wiper arm W-1 will be connected to terminal 316 and through lead `17 to terminal 320 of unit 134 and through closed contacts 360, 361, terminal 183 and lead 133', terminal 172 of the storage unit 102 will also be connected to negative main 46 to energize relay 107 of bank lvl-7 to close its four pairs of contacts. The key K related to number 1 of the typewriter 21 may then be pressed to type such number at position 21 on line 5 and to close its associated switch 23 thereby energizng relay R-1 of coding unit 81 to close its pair of contacts 83, S4 to connect terminal 94 to negative main 46. As a result, terminal 100 of memory unit 102 will be connected to negative main i6 to energize relay 106 of bank M7 related to number 1 to close its contacts 112, 131 move arm 113 against contact 162, the closing of contacts 111, 124 providing a holding circuit for said relay. Upon release of key 1, the carriage will move to position 22 on line 5 and the wiper arms of stepping switch S-3 will move to engage contacts 18.

As Contact 1S. of bank. i-1 of'stepping switch S-3 isrv connected to terminal 231 and thence by lead 232 to terminal 34 or" the typewriter the carriage return solenoid 32 will be energized to rotate the platen to line 6 and to return the carriage to position l on such line. Such movement of the carriage will cause the wiper arms to move to engage contacts 19.

With the wiper arm W-1 engaging contact 19'of bank B1 of stepping switch' S-3, the terminal 276 willu be connectedfto negative main'A 46l as will be 'the'terminal 22 33 of the typewriter and the 'space bar be l 4- to move the carriage to the second position on line'sv6 again causing the wiper arms of stepping switch Sl-3 tol move to engage Contact 20. Y Y i 'the operation above described will again be repeated to move the carriage to the third position on line 6 antl thence to the fourth position, and the coil 233 'of stepping switch 8 3 will be energized to move its wiper'arms to engage contacts 22. Thus the negative main will be connected through wiper arm W-l to terminal 187. ,l

il? is connected by an associated lead 186 to terminar 154 of bank lvl-1 of storage unit 102. Hence, through lead 149, closed contacts 113, 157 of relay 106, lead 15S and main 159, the terminal 161 is connected to negative 46. Through lead 218 (Fig. l) the *terminai or" typewriter 21 is connected to negative main 46 energizng space bar solenoid 31 to move the carriage to the iitth position on line 6. p l

Snch movement will rotate cam 50 and in the manner previously described, the wiper arms of stepping switch S-S will move to engage contacts 23. As contacts 23 and 24 are connected to terminal 276, the carriage will move two spaces as previously described to position seven on line 6 and the wiper arm W-1 of stepping switch S-3 will move to engage Contact 25 connecting terminal 188 to negative main d6. Referring to Figs. l and 6, terminal 153 will also be connected to negative main 46, and through leaf. 148, closed contacts 113, 157 of relay 105, leads 1513, 159` the terminal 161 will be so connected. AsY previously described, the space bar of the typewriter 21 wiil he actuated to move the carriage one space to position 8 and through cam 5S the wiper arms of stepping switch S-S will move to engage contacts 26.

As contacts 26 and 27 are connected to terminalV 276, in the manner previously described, the carriage will move' two spaces to position 16 on line 6 and the wiper armv W-1 wiii move to engage Contact 2S to connect terminall 139 to negative main 46. Through lead 186, terminal 152 of storage unit 1512, lead 147, closed contacts 1 13, 157 of relay leads 158, 159, the terminal 161 is also connected to negative main 46 and through lead218'the space oar solenoid 31 is actuated to move the carriage to position 11 and through cam 50 the wiper arm W-l of stepping switch 5 3 will move to engage contact 29. The carriage wiii then move two spaces to position 13 on line 6 the wiper arm W-l will move from con? tact 29 to 3@ in the manner previously described and thence," to Contact 31 to connect terminal 190 to negative main 46.

Through lead 186, terminal 151 of storage unit 1,02 will be connected to negative main 46 andA through lead` 146', closed contacts 113, 162 of previously energized relay 103 ot bank Bft-1 related to number 4, leads 163, 164, terminal will be connected to negative. Thence through lead 217 and terminal 36, code bar lever' solenoid 35 of the typewriter 21 will be energized to type a code'- oar at the thirteenth position online 6 which is at the fourth code region on this line and represents the number 4 as shown in the code set forth in Fig. 12. I

After the code bar lever has returned, the' cam 50 lwill rotate to advance the wiper arm W-1 of stepping switchv S-3 to engage Contact 32. 1n' this position terminal 281' will be connected to negative main 46 and as previously described, the carriage return solenoid 32 will befactuated to rotate the platen to line 7 and move the carriage totlief iirst position on line 7 and due to the rotation of cam 50' to advance the wiper arms to engage contacts 33.

The operations above described will then be repeated with respect to line 7. Thus, when wiper arm W-l ofV stepping switch S3 is engaging contacts 36,1, 39, 42 andV 45 and the carriage is at the 4th, 7th, 10thV and 13th" positon on 1tine 7, terminals 191, 192, 193 and 194 will b e connected'to negative main 46 as will terminals 154,153,4 152, 151 of memory bank' lvl-2V respectivelyi 's only" relays 104 and 105 of bank Mi-Zr'elatedto 'tli ii'fil areas-7s- 6 are energized as previously described, the code bar lever solenoid 35 will be energized only when the wiper arms are engaging contacts 39 and 42 to print code bars at positions 7 and l0 on row 7, i. e., the second and third code regions representing the number 6 as shown in Fig. 12.

Y As only relays 105 and 1l6 of bank lvl-3 related to the number are energized, as previously described, further advance of the carriage and the stepping switch wiper arm W-1 to engage contacts 43 and 51, will cause code bars to be typed at the sixteenth and nineteenth positions on row 7, i. e., the iifth and sixth code regions representing the number 5. When the wiper arm W-l of stepping switch S-3 reaches the 52nd contact, terminal 276 will be connected to negative main 46 energizing space bar solenoid 31 to advance the carriage one space to position 21 on card 11. Upon movement of the carriage and rotation of cam 5t?, the wiper arms of stepping switch S-3 will be advanced to the O or home position opening contacts 244, 247 and moving arm 245 against contact 249 to break the circuit for coil 233.

When contact 52 of bank B-2 of stepping switch S-3 is engaged by wiper arm W-Z, terminal 323 will be connected to negative main 46 and through lead 323', and terminal 27), coil 234 of stepping switch S-4 will be energize-d to open its contacts 243, 245. Upon deenergization of coil 234 when contact 52 of bank B-Z of stepping switch S-3 is no longer engaged by the wiper arm W-2, the wiper arms or" stepping switch S-4 will move to engage contacts 1; contacts 244, 247 of coil 234 will close and arm 245 will engage contact 249 to place coil 234 in circuit to control the wiper arms of the stepping switch S4.

In the twenty-second and twenty-fifth position on line 7 when wiper arm W- of stepping switch S-4 is engaging contacts 2 and 5, terminals 197 and 193 will be connected to negative main 46 as will terminals 152, 151 of bank M-3. However, as previously described, as only relays 1tl5, 166 are energized, the code bar lever solenoid will not be actuated.

In the twenty-eighth, thirty-first, thirty-fourth and thirty-seventh position on line 7, when wiper arm W-i. is engaging contacts 8, 11, 14 and 17, terminals 199, 236, 201 and 202 will be connected to negative main 46 as will terminals 154, 153, 152 and 151 of bank lid-4. As only relay 105 of bank lvl-4 related to number 2 is energ'ized, the code bar lever solenoid 35 will be energized only when the wiper arm is engaging contact 11 to type a code bar at position 31 on row 7, i. e., the tenth code regionrepresenting the number 2.

The wiper arm W-1 of stepping switch 8 4 will have Y advanced as previously described until it engages contact 18. Thus, the terminal 231 is connected to negative main 46 to actuate the carriage return mechanism of typewriter 21 to rotate the platen one space and move the carriage to the 'iirst position on Yline 8. Cam 5% will rotate to move the wiper arm W- to engage contact 19 which is also connected to terminal 231, and the platen will rotate to line 9 and the carriage will move to the iirst position on this line and through the rotation of cam 50 will move the wiper arms to engage contacts 26.

Thus, terminal 224 is connected to negative main 46, and through lead 219, terminal 223 of renewal unit 184 will beso connected. As a result, through closed contacts 354, 355, terminal 275, leads 274, 277, terminal 33 of typewriter 21 will be connected to negative main 45 and the space bar solenoid-31 will be energized to move the carriage to position 2 on line 9 and rotate cam 5t? to advance the wiper arms of stepping switch to engage contacts 21. This operation will be repeated until contacts 23 are engaged, at which time the carriage or the typewriter will be at position 4 en line. 9. When the wiper arm W-3 of stepping switch S-4 engaged contact 29, terminal 332 was connected to negative main 46 as was terminal.334of renewal unit 184, f through leadf333.-V

However, as contacts 362, 363 of unit 184 are open due to the energization of such relay when the key K was pressed, this has no effect.

The wiper arms of stepping switch S-4 will advance until they engage contacts 52 and in the manner previously described, the date typed on row 5 of the card 11 will be decoded and as this code is September 51 or 9 5l, such date will be typed in the form of code bars at positions seven, thirteen, sixteen, nineteen and twentyeight or code regions 2 and 4, 5 and 6 and 9 on the ninth row representing the Vnumbers 9 5l respectively by reason of the energization of the related relays in banks M-5, M-6 and M-l of the memory unit.

As terminal 224 will be connected to negative main 46, when contact 52 of bank B-1 of stepping switch S-.4 is engaged by wiper arm W-1 as previously described, the space bar solenoid 31 will be energized to move the carriage one space and the wiper arms of switch S-4 will move to O or home position.

. At the same time, wiper arm W-Z will connect terminal 331 to negative main 46 to energize coil 235 through lead 331. As a result, contacts 243, 246 of coil 235 will open. When wiper arm W-2 moves away from contact 52 and terminal 331 is no longer engaged, coil 235 will be de-energized and the wiper arms of stepping switch S-S will engage contacts 1 and contacts 244, 247 will close and arm 245 will engage contact 249.

After the code on the ninth line of card 11 has been typed and the wiper arms of stepping switch S-S have moved to engage contacts 5, terminal 281 will be connected to negative main 46 through lead 282 and the carriage return solenoid 32 will be energized to rotate the platen to line 1t? and move the carriage to the rst position on such line, the rotation of cam 50 advancing the Wiper arms oi' stepping switch S-5 to the sixth contacts.

As contact 6 on bank B-1 of stepping switch'S-S is also connected to terminal 281, the carriage return solenoid 32 will again be energized. However, as the carriage is already at the rst position, it will not be moved and as only the lower edge of the card 11 is held by the platen, the rotation of the platen will facilitate removal of the card from the typewriter by the operator without need for manually turning the platen.

The rotation of cam 50 due to the last actuation of the carriage return bar will move the wiper arms of stepping switch S-S to engage the seventh contacts.

As wiper arm rl/ 3 of stepping switch S-S is connected through terminal 237, lead 225 to terminal 226 of section A of unit 222 and thence through closed contacts 491, 402, lead 415, contacts 332, 334 of relay 375, which were closed when the Set button 336 as initially pressed at the beginning of the cycle, to negative main 46 and as all or" the succeeding contacts of banks B-3 and B-4 of stepping switch S-S after contacts 6 are connected to terminal 346, such terminal 346 will also be connected to negative main 46 and hence coil 235 will be energized through lead 346 and closed contacts 244, 247, and 243, 246 to open its contacts 243, 246. This will de-energize the coil to advance its wiper arms. Repeated energization and cle-energizatien of coil 235 will thereby occur rapidly to advance the wiper arms of stepping switch S-S until they reach contacts 52 and then move back to 0 or home position at which time the homing action will stop.

' When wiper arms W-l. and W-Z of stepping switch 8 5 are engaging contacts 52, terminals 335 and 343 will be connected to negative main 46. When terminal 336 is connected to negative main 46, through lead 337, terminal 3330i section A of unit 222 will also be connected to energize the counter 423 to indicate tha-t a card has been completed.

p When terminal 343 is connected to Vnegative main 46, through lead 344, terminal 345 of section A will alsobe ci?) connected to negative main 46 energizing coil 422. of relay. 419 to open its contacts 123, 42.4 iandy 418,442.1. Opening of contacts 423, 424 will break the circuit from negative main 46 through leads 426 and 279 (Fig. l) to coil 366 of relay 351 of renewal unit. 184 so that the relay contacts will move to the position shown in Fig. 9. Opening or contacts 41S, 421 will break the holding circuit for coil 33sa or" the Set' relay 375 in section A of unit 222 to ready the latter for the next cycle and by the opening of contacts 391, 393 of relay 399 in section A, the circuit to relay 4t2 (Fig. 2) will be broken -to deenergize the drive motor of typewriter 21. The opening of contacts 41S, 421 (Fig. 4, section A) will also break the circuit to terminal 221 to open the circuit to the coils of -the relays in the storage unit 162 to ready it for the next cycle.

At this time the typed cards 11 and 12 can be removed from the master and slave typewriter, another card placed in each typewriter, the Set button 386 pressed and the above operation repeated.

lf an error is found after the cards in the master and slave typewriters have been partly typed and the wiper arms of stepping switch S-1, for example, have been advanced toward contacts 52, such cards may be discarded and the equipment may readily be reset by merely pressing the Reset" button 414%. As a result, relay 399 will be energized to open its contacts 401, 492; 465, 4%; 467, 49S and to close its contacts 403, 404. In addition, contacts 11' and 413'A will close to energize coil 422 of relay 419. As a result, through the opening of contacts 418, 421 of relay 413, the circuit to terminal 144 of the storage unit 102 will be broken to reset any of the relays in the storage unit 192 that had been actuated.

When contacts 461, G2 are opened, the circuit from negative main t through closed contacts 392, 394 of relay 375, lead i5 and contacts 401, 492, terminal 226- and lead 225 to terminal 237 (Fig. 8) will be broken to remove the negative potential from the wiper arms Wel', iV-2, W-3 of the stepping switches. When contacts 463, Agile are closed, a negative potential will be applied to terminal 239 (Fig. 8) and hence to the wiper arms W-4 of all of the stepping switches. As a result, the terminals 293, 365, 327, 335 and 3456 of all ot' the stepping switches and the associated coils 231 to 235 will be connected to negative main 46 to effect actuation of all of the stepping switches whose wiper arms are notin the or home position.

When contacts 4535, 406 ofv section A of unit 222 (Fig. 4) are opened, the circuit to the coil 389 of the Set relay 375 will be broken to recycle the latter".V When contacts 467, 49S are opened, the circuit to the counter 42S will be broken so that in the event the fifthY stepping switch was in operation and it homed to terminal 336, no potential will be applied to actuate the counter, such count not being desired as a defective card is present.

As previously described, after the date of lunev 5.2VV had been typed on tne first line of the card 1 1, the letter R was typed when the wiper arms of stepping switch S 1Y were engaging contacts 24. This caused the relay 351 of' unit 184 (Fig. 9) to be energized.

If the "Reset button 414 is pressed after relay 351 is energized by reason of the opening of contacts 423, 424 of relay 419 (Fig. 4) the circuit tocoil 366 of relay 351 through closed contacts 352', 353 is broken and the renewal relay 351 will be set for the next operation.

In the event that it is not desired to type a code on the card for the previous expiration date, the l'ettei R would not be typed, but instead the space bar pressed to advance the carriage one space in the manner previously described to advance the wiper arms of stepping switch S- to contacts 25. The. operations. previouslyA described would then be performed until the wiper armsV of stepping switch S-4 reach contacts 2i). The negative potential from the wiper arm W-l of steppingI switch S4 WORM be applied t0. terminal. 3.32, and. through. lead 333 (Fig. 1), terminal 334 of unit 184 (Fig. 9), normally' closed contacts 362, 363 of unit 184, terminal 330, lead 329 to terminal 335 of control unit 179 and the terminal 254 of coil 234 of stepping switch S-4 would be connected to negative main 46 to pulse such coil as previousiy described to move the wiper arms of stepping switch S-f to 0. position.

When such wiper arms reached the 52nd contact, terminal 331 would then be connected to negative main 46 to actuate coil 235. As previously described, stepping switch S-S would then be actuated to connect negative main 46 through wiper arm Vil-2, the drst contact of bank B-2 of stepping switch S-S, terminal 339, -through closed contacts 364, 365 of unit 184 to terminal 346 and thence to coil 235 to advance the wiper arms of stepping switch 5 5. When contacts 5 and 6 of bank B-1 were engaged by wiper arm W4., the platen would be turned two lines and the carriage advanced to the beginning of the line and the wiper arms would be advanced to position 7 and the stepping switch S5 would then be homed as previously described.

It is to be understood that any desired arrangement of the circuit connections of the control unit could be provided so that the data recorded on the cards in the master typewriter could be spaced as desired on one line or separated by one or more lines and the coded information can be on successive lines or spaces. Furthermore, the data on the card in the slave typewriter can be broken up and typed into any number of lines within the limits of the card.

Although the invention has been illustratively described with respect to its application in the subscription fulfilment iield, it is readily apparent that it could be used in a multiplicity of other lields. Thus, for example, the data recording means could be a cash register modified to deliver impulses depending upon the amount of the sale, a code number for the salesman, and a code number. for the item for example, and the code designations typed on a card which could be used in a suitable classitying equipment to classify such cards according to sales men and stock items as well as the amount of the sales.

The system could also be used as an automatic type'- Writer with predetermined tabulating on a plurality ofVV l lines by appropriate connections in the control unit.

The illustrative applications of the equipment herein given are by no means all inclusive and all applications possible within the ambit of the claims are withinj. theY scope of the invention. from its broader aspects.

Although the code designation is illustratively shownY as a bar typed on a card, it is within the scope of the invention to employ code designations that emit' or reflect?- Waves of any desired frequency between very wide limitsor produce a field illustratively an electro-static or electro-magnetic field.

While' the invention preferably uses imperforate cards, itis within the scope of the invention, as defined in the claims, to utilize perforations as the code designations.

Where imperforate cards or other carrying media are used with the items of indicia and codes thereon, such indicia and codes may readily be obliterated or covered andthe cards or other carrying media may be re-usedY with new or added indicia and/or codes.

ln the illustrative embodiment herein shown, the carry'- ing media for the indicia, codes or data are cards. However, it is within the. scope of the invention to use other' types of carrying media such as sheets, strips, film or the'l like.

As many changes could be made inthe above systenr andiequipment, and many apparently widely different cru-f bodimentsot this invention could be made without de?. parting` from the scope ofthe claims, itis. intended that.' all matter contained Vin the above description, or; shown. ink thel accompanying drawingsshall. be interpreted as: illustrative andnot'in a limiting sense. q
