Patented May 6, 1930 UNITED STATES PATENT OFFICE CLAIR D. LAKE .AND RALPH E. PAGE, OF BINGHAMTON, NEW YORK, ASSIGNOIRS T0 THE TABULATING MACHINE COMPANY, OF ENDICOTT, NEW YORK, A CORPORATION 0F NEW JERSEY TABULATING MACHINE,

Application led February The present invention covers improvements in tabulating machines, more specifically printing tabulators, and particularly of the type disclosed in copending application, Serial No. 639,153, filed May 15, 1923.

These machines, as is well known, analyze perforations in record cards and after analyzing the perforations may print on a sheet of paper all or part of the data contained on the cards.

It may transmit the data from successive cards to counters, or accumulators, printing the total of data accumulated from all the cards, or from particular groups of cards if they are arranged in such groups. It may print data from each card and the total of such data for each group of cards. It may also print with each item a designation of the group to which the data belongs. ther combinations of similar nature may be effected.

In the machine described in the above application the recording of group numbers was effected hv entering the group number into an accumulator counter, then, if it was desired to print this group number, 'the counter was read by reading devices, and these reading devices controlled the type elements of the machine so as to print the group number.

Among theobjects of our invention is the provision of means for printing the designating number of a group of cards from the first card of the group and then suppressing the the paper feed so that when the totals of that group are printed they are in alignment on the record sheet with the group number printed from the 'irst card of the group.

Another object of our invention is the provision of means for printing group numbers direct from the cards.

Another' object is to provide means whereby all printing operations are automatically performed at comparatively slow speed and all non-printing operations at much higher speed.

Another object is'in provisions for printing the group number from the first card of agroup while suppressing the printing of corresponding items from that Card. and subsc- 5, 1925. serial No. 6,981.

quently printing the total of the group in alignment with said group number.

Another object is the provision of simpler means for printing the group number from each card of a group in alignment with data from that card, and then omitting the printing of said group number when the totals of said item are printed.

Another object is the use of a two speed driving motor the speed of which is automatically varied to provide comparatively low speed for printing (listing), and a higher speed for non-pril'iting operations.

Other objects reside in the provision of a rearrangement of contacts and circuits in the machine whereby the use of certain contacts heretofore employed may be obviated and whereby other contacts and circuits may be used to perform novel functions which will hereinafter be set forth.

Other objects and advantages will be hereinafter set forth in the accompanying specification and claims and shown in the drawings which by way of illustration show what is now considered to be the preferred embodiment of the invention.

In the machines described in the previous application group indicating was effected by counters, the group number being entered into a counter for a first card of a group. Thereafter the entering of further group numbers c after the first card of a group.

In the machine forming the subject matter of the present application the necessity for said group indicator cont-acts for each group designating column is obviated. In place of entering group numbers upon a counter or counters the group number as taken from the card is arranged to directly control the printing lmechanism of the machine. The feature of suppressing the entering of items into the accumulator by the group indicator contacts after the passage of the first card, is obviated. Group numbers may or may not be entered into the accumulator but, if entered, these group numbers will be accumulated therein, there being no suppression of the accunuilation of group numbers.

With our resent machine provision is made for varylng the speed of operation when the tabulator is running as a straight tabulator without listing. In other words, while the first card passes through the machine and the group number is being printed therefrom provision is made for running the printing attachment at the usual printing or listing speed because otherwise the mechanism would be damaged. After the first card has passed and the group number is printed the machine automatically assumes a higher speed for tabulating the remainder of cards in that group.

In describing the machine two conditions must be considered. The first or tabulating condition makes records of grou numbers and totals only. The second or listing condition'prints the individual items with the group numbers and then prints the totals of the items without the group numbers.` If the machine is to be set for tabulating (totaling) items without listing the individual items, i. e., the first condition mentioned above, so that only totals and group number are printed upon the record sheet, provision is made for initially printing the group number upon the sheet, as shown in Fig. 10. Subsequently, when-totals have been accumulated by the machine, these totals are entered upon the Irecord sheet in alignment with the pre viously printed group number, asshown in Fig. 11 of the drawings. l

The second or listing condition has a different operation. Here both group number and J items are printed concurrently, the group number being repeated for each item as shown in Fig. 12. Finally totals are printed without the accompanying printing of t-he group number.

The instrui'nentalities for bringing these operations about, so faras the mechanism of the machine'is concerned, are directed particularly to constructions involving the operation of the listing cam and the parts controlled thereby, and also the operation of the paper feed.

A clear understanding ofthe present machine will best be had by describing the operation of the previous machines upon which the present invention is an improvement.

In the previous machines described in the copending application above referred to, the rising of the type 266 (Fig. 3), when the machine was set for listing, was brought about by rocking shaft 305 through the instrumentality of listing cam 311. When totaling operations were to be effected, the type were raised by means of total cam 301. In the former machine the listing cam 311 was its.;

driven at all times when the tabulating machine was operated. If it was desired not 1o liz-tt the individual items but to only tabulate, i. e. print totals, provision was made for withdrawing the listing cam roller from cooperation with the listing cam.

l-Iaving now described briefly the previous construction, the modified construction of the present machine will be described.

Fixed to the listing cam shaft 294, adjacent the listing cam 311, is a clutch disk 500 (Figs. 3, 6 and 7) provided with a notch 501. Listing cam 311 is loose upon the listing cam shaft, and during listing operations this listing cam is clutched to shaft 294, by the means which are now to be described.

Pivotally mounted upon the listing cam 311 is a clutch member 502. The clutch dog 502 is normally drawn into engagement with disk 500 by means of a spring 503 which, at its opposite end, is fast to a part 504 extending over and terminating in a nose 505.

' The clutch dog 502 is provided with a tail or pawl portion 506, which is adapted to cooperate vwith a shoulder portion '07 upon a rocking lever 508. Lever 508 is also provided with a supplementary pivoted latch 509`which allows the member 504 to pass itand prevents backward rebound of the same. For normal listing operations, lever 508 is in the positionshown in Fig. 6. )Vith the parts in this position clutch dog 502 is in engagement with the notch 501'and this couples the listing cam 311 to the listing cam shaft 294. Thelever 508 is iixedlymounted upon a stub shaft 510 (see Fig. 23), which shaft is journ'aled vin lugs 511 fixed to a bracket 512 fast to the frame of the machine. It will be understood that shaft 510 mustbe rocked in a counterclockwise direction to allow the clutchdog 502 to engage for listing. This rocking is effected by the list and i y non-list shaft lever of the tabulator.

. non-list lever of the ta-bulator.

Referring now to Fig. 13: 316 is the list- This lever is fast to a rod 317, and around this rod is the usual compression spring 319 heretofore employed. As in the previous construction the shaft 317 is provided with a shifter fork 318 (Fig. 17) coacting with cross pins 320 on a shifter rod 300. The arrangement is such that by rocking lever 316 from the tabulating or non-listing position, as shown in Fig. 13. to listing position (i. e., in the direction indicated by the curved arrow), the shifter rod 300 will be shifted downwardly from the position shown in Fig. 13. In place of connecting the slip or shifter rod 300 to the follower 310, which cooperates with the listing cam 311 as in the previous construction, the follower 310 is arranged so as to be always in engagement with the cam slot in cam 311. It is entirely free of control by the shifter rod 300. Upon the end of the shifter rod 300 there is provided a beveled nose 513 (see Fig. 19), which nose, when 300 is shifted do\\'n\\ardly, separates two fingers 514 and 5,15. in vFig. these. parts are shown in non-separated positimi. Finger 515 (see Fig. 6) is fast upon a pivoted arm or lever 516. which in turn is fixed to the stub shaft 510 previously referred to (see Fig. 23).

The other cooperating finger 514 is integrally disposed on a supplementary arm 517 (Fig. 23), which is substantially similar in contour to 516. Arm 517, instead of being pinned to shaft 510, is loose thereon, and this arm 517 has secured thereto, preferably adjnstably, a supplementary arm 518 (see Fig. 6) carrying upon its end a roller 519 adapted to cooperate with a notch 520 in the. listing cam 311. l/Vhen the shifting lever is in listing position the roller 519 is out of engagement with the notch 520, as shown in Fig. 6, but when the shifting lever is in the tabulating position this roller 519 is in engagement with the notch, in the manner shown in Fig. 7. The purpose of the roller 519 is merely to positively locate cam 311 which carries dog 502 so that 502 will drop cleanly into slot 501 when shifting lever is shifted to listing position.

The foregoing has described the means for raising the type 266 during the listingy or individual item printing operations. If, after listing, they printing devices are to be operated to take a total a cam 301 on the so-called total printing'shaft 315 rotates causing elevation of an arm 302 provided with a cam follower. which arm is loosely mounted on shaft 305 (Fig. 14) and is provided with an abutment 303 which is adapted to contact with an adjustmentvscrew 303a carried by the bell crank lever 304 thus rocking bell crank 304 in a clockwise direction and similarly rocking shaft 305. As previously described the rocking shaft 305 through arms 306 (Fig. 3)

' is adapted to raise the type 266. To drive the total printing shaft 315 the customary l reset motor RM is provided and this, through a shaft and worm 339, drives a worm wheel 340. Fixed to worm wheel 340 is a ratchet disk 341 (Fig. 4). Fast on shaft 315 is a socalled printing cam 342. Fast to this printing cam is a bar 343 which in turn carries a clutch. dog 344.` The clutch dog overlies ratchet 341'and is normally disengaged. Engagement of the dog with the ratchet is permitted when the reset clutch magnet 233 is energized. The armature 346 of this magnet is pivoted at 347 and has connectedto it an extended arm 348 which is notched to engage the tail of the one revolution clutch dog 344. Upon the energization of magnet 233, latch 348 is elevated and the clutch dog 344 drawn by its spring into engagement with the ratchet 341. Subsequently to this engagement the printing cam and printing shaft 315 rotate in unison with the ratchet, making one revolution. During this single revolution of these parts magnet 233 becomes Adeenergized, permitting latch 5348 .to reengage the clutczh dog and disengage it from the ratchet 341. Part 348 vis restored by a spring (not shown) and also by block 349 and pin 350. As in the previous construction a rock arm 354 (Fig. 4) is provided cooperating with the cam 342,

which rock arm is fixed-t0 a total print shaft the manner described in the previous application. The rocking of the shaft 355 serves also to rock a bail 355a which opens certain contact devices NL1, NL2, etc., for a. purpose which will! hereafter be described.

The foregoinghas explained the general operation when the tabulator is set for straight listing followed by the taking of a total of the listed items. It will now be assumed that after such a listing run and total is taken it is desired to set the tabulator for straight tabulating, omitting printing of 'items and printing only totals and `group numbers. Figs. 10 and 11 show the report which is printed under these conditions.

The first operation is to shift the tabulator list lever 31,6 from the listing position to nonlisting or tabulating position. Fig. 13 shows the tabulator non-list lever 316 in so-called tabulating position.- With this condition of,

parts the nose 513 (Fig. 19) of the shifter rod 300 will be in the position shown in Fig.- 19. Consequently inger pieces 514 and 515 will not be separated. However, upon shifting the shifter lever from the previous listing position to the non-listing position the finger pieces 514 and 515 will have moved from the open position shown in Fig. 6 to the closed position shown in Fig. 3 and will have permitted arm 508 to rock from the position shown in Fig. 6 to that shown inFig. 3 with the end of memberi 508- on top of the shouldered tail of the clutch dog 502. At this time in the cycle the clutch dog is not disengaged from the notch 501 on disk 500. It therefore follows that uponthe first machine cycle the listing cam 311 will make one revolution and at the completion of'this revolution the dog 502 will be thrown out, assuming the positionillustrated in Fig. 7. This single revolution of the listing cam 311 is utilized for printing the group number on the listing sheet as shown in Fig. 10 of the drawings. As shown in Fig. 11 the totals on the record sheet are eventually printed in alignment with the previously printed group number. It is therefore necessary to provide means for preventing the aper feed from the time that the group num er is printed until the total printing operation is completed. v

After the listing cam 311. has made one revolution the clutch dog 502 is disengaged as above explained and remains disengaged until a` total is taken. Upon the taking of a total, magnet 233 is energized actuating armagagement with the cam 'dog 344 to permit the machine to take a total. The armature 3 46 and shaft 347 rock together and the rocking of shaft 347 causes an arm 352 to rock clockwise (Fig. 5). Arm 352 engages a pin 621 on an arm 622 fixed on shaft 510 and thus rocks this shaft counterclockwise thereby rocking arm 508 counterclockwise, releasing dog 502 and allowing it to reengage notch 501 to place the parts in condition for listing the following group.

The control of the paper feeding mechanism, its construction and operation are as follows:

Link 336 at its upper end connects to a- 330. Shaft 305 always operates the paper feeding mechanism when it must feed the vaper on the up stroke of the type bars, as or every revolution of cam 311 when listing is being performed, an also for one revolution during the first card cycle when tabulating operatlons are being performed. As will be shown later, lever 330 actuates lever 334 on the down stroke of the type bars to draw down on link 336 only during the latter part of a total printing and reset cycle when the achine has been previously set for listing.

When the machine is set for listing the operation of the paper feeding mechanism is as follows: Lever 316 (Figs. 13 and 16) is shifte'd manually in a counterclockwise direction to listing position and, as rod 300 is moved to the right, block 603 (Figs. 8 and 16) ture 346 to lift the cam latch 348 out of the enlll) attached` rigidly to shaft 317 makes contact with a rejection 604 of latch 337b which is pivotal y mounted at 606, and holds latch.

337 in such position that it cannot engage block 337 fixed to member 337. Therefore parts 337* and 337b are inoperative while the machine isset for listing and are used as will be later explained for tabulating only. While listing, shaft 305 rocks first in a clockwise and then in a counterclockwise 'direction for eac'hrevolution of cam 311 (Figs. 14 and 15). At the end of shaft 305 is an arm 338 having at its upper end a pin 600. As shaft 305 1s rocked in a clockwise direction this in 600 contacts against a shoulder on mem er 337, rocking the unit comprising parts 334, 333 and 337 about its pivot 601 and drawing down link 336, thus feeding the paper one line space. This occurs while the type bars are being raised.- It will be seen iao iXed in part 333 of that during listing operation the paper is fed one line space for each cycle of operation of the machine or each revolution of cam 311. On the down stroke of the type bars shaft 305 is rocked in a counterclockwise direction and allows lever 334 to resume its former position.

At the end of a group of cards which have been listed a total is taken. When the machine takes a total cam 311 comes to a stop and shaft 315 on which are mounted cam 301 and gear 328 makes a complete counterclockwise revolution, as previously described. Cam 301 rocks shaft 305 (Figs. 14 and 15) through the same arc as described above for cam 311, so that the paper is fed the usual one space before printing a total. Early in the second half of the total printing cycle shaft 305 completes its rocking cycle and link 336 rises to normal position as parts 334, 333 and 337 return to position shown in Fig. 8.

After a total is printed it is desirable to leave a blank space on the paper before listing the first item of the next group.- The paper is fed this eXtra space during the last part of the total printing cycle in the following manner: A pin 329 on gear 328 contacts with lever 330 which is pivoted loosely on shaft 305, rocking 330 in a clockwise direction. Lever 330 has an upwardly extending arm 330n to which is connected a slotted link 602. As lever 330 is rocked by pin 329 the lost motion in link 602 is taken up, stretching spring 608, and link 602 then acts on a pin the unit consisting of parts 334, 333 and 337. This rocks the unit in a counterclockwise direction thus drawing down link 336 a second time during the total printing and reset cycle to feed the paper an extra space after total printing. The slot in link 602 and the spring 608 above mentioned are necessary to hold lever 330 normally in a counterclockwise position to provide clearance while parts 337% 337D and 604 are operative as will be later described.

If it is desired to perform tabulating (as distinguished from listing) operations onthe machine it is necessary to shift lever 316 to tabulating position. As has been pointed out, when the machine is set for tabulating, the listing cam 311 will turn one revolution (during the irst card cycle) starting from the position shown in Fig. 3, being stopped by the arm 508 after the completion of one revolution. During this revolution the shaft 305 will be rocked and the paper fed one line space, as above described. But as the shifting of lever 316 to tabulating position has moved block 603 out of contact with projection 604 block 337a becomes locked in position shown in Fig. 9 by latch 337b actuated by spring 607. The spacing of the paper takes place during the early part of this cycle. During the same cycle after the spacing has taken place the printing eii'ected. In the present instance, that is, during tabulating operations, this printing from the first card will be of the group designation number only. As the listing cam'311 is locked against operation at the end of the first card cycle there will be no further printing during the c0ntinued operation of the machine until a total istaken. In the meantime as the operation of the paper feed mechanism has been suppressed-by the latchiiig of block 337a by latch 337) the line on which the group number is printed remains in printing position so that when the total is eventually printed it is on the same line with the group number, as in Fig. 11. When the total is printed shaft'305 is again rocked in a clockwise direction, this time by cam 301, but no movement of 334 or 336 takes place on this up stroke of the type bars due to lever 337 being held by block 337 and latch 337". .The result is that paper is not fed at this time and the total is printed on the same line as was the indication number during the first tabulating cycle. Near the end of the revolution of shaft 315. after shaft 305 has returned to its normal position, pin 329 on gear 328 makes contact with lever 330 and causes it to rock about pivot 305 in a clockwise direction, the slot in link 602 attached to its upper end allowing it to move freely. As lever 330 nears the end of its clockwise rocking movement its upward projection 330a acts against projection 604 of latch 337", releasing block 337a and allowing 337 and attached members, including link 336, to resume normal position, with the shoulder 0f 337 against pin 600. As soon as pin 329 has passed the end of lever 330, spring 608 draws lever 330 to its normal position. It will be `observed from the above that lever 330 has two entirely different functions to perform, depending upon whether the inachine is set for tabulating or listing.

y Referring now to Figs. 20 ,and 21, the parts show the usual group indicator and automatic control unit. As in previous machines shaft 398 is rotated in unison with the tabulator shafts during tabulating operations and arm 404 is rocked during resetting and total printing operations. 92 is the group indicator magnet. Upon the energization of this magnet latch 417 is attracted releasing arm 418 fast to bail 416 which thereupon rocks clockwise under the influence of spring 419. Cooperating with bail 416 are three contacts G11, Gl3 and GI8 instead ofthe ten group indicator contacts heretofore employed. Contacts G11 and G13 are normal open contacts and GI8 are closed so that upon the rocking of bail 416 un'der control of inagn'et 92 contacts GI8 will open and G11 and G13 will close. This action'occurs at or towards the end of the first card cycle of a group. Bail 416 is restoredV in an anticlockwise direction during the reset and total printing cycles by means of arm 404 and shaft 400.

Contacts 71 and 73 are the usual automatic control contacts which are controlled .by automatic control magnets' 72. These parts being the same as in previous machines require no detailed description.

The machine is also provided with a gear transmission 257 (Fig. l) which is shifted when the tabulator is set for listing to drive the parts at the low printing speed. The transmission is provided with contacts 250 (shown on the circuit diagram) and which are closed as in the previous machines when the transmission is set to drive the machine at reduced speed.

' Referring now to the diagram views (Flgs. 26a and 26h), 50 designates a stack of record cards which are adapted to be advanced one at a time by means of a picker 51 into engagement with feed rolls 52. The feed rolls ultimately advance the cards to the discharge stack in the usual manner. Rolls 52 are driven by gearing generally designated 53 which in turn is driven by a tabulator motor TM through the usual magnetically controlled clutch 54. This clutch is controlled by clutch magnet 55. Cards are advanced past upper brushes 55 and contact blocks 56, and thereafter past lower brushes 59 and contact blocks 60. The upper and lower brushes are respectively carried by common bars 57 and 58. Upper and lower card levers 61 and 62 are provided, which card levers are respectively adapted to close upper card lever contacts 63b and lower contacts 63a and 64a. From the upper and lower brushes cabled wires 65 and 66 are shown leading to plug sockets on the tabulator plugboard 254. Sockets 67 are for the upper brushes and multiple sockets 68 are for the lower brushes. On the plugboard there are also sockets 69 which are connected directly to the counters and supplemental sockets 70 which are direct- Y ly connected to the printing magnets without having any counter magnets associated there'- with. On the upper end of the plugboard there is shown a circuit diagram of the automatic control'unit. When certain columns are to be used for automatic controlling, plug connections are inserted between sockets 67 and sockets 670 of the automatic control unit. From socket 680 of the control unit plug connections may be made between 680 and 68. From any plug sockets 68 connections may be made as desired to 69 and 70. It will be understood that the automatic control can be plugged in any desired columns, also that the automatic control may be plugged from 680 to 68tand thence to 70 without plugging up corresponding plug sockets 69. In nthis way the control number may be printed on the extra listing banks without sacrificing counter capacity when this is done. The automatic control unit is the same as heretofore em-` .of a

ployed in machines and requires no detailed description. There is an automatic control circuit 74 which extends serially through all contacts 7 3 of the control unit, as in the previous machine.

In the statistical work handled by tabulating machines the record cards are usually arranged in groups, each card of the group bearing a distinguishing number which serves to identify that particular group, and it is customary for the machine to indicate the group number of each group for purposes of identification.

In the machine described in the previous application this group indicating was effected by the regular tabulating counters or accumulators, the group number being entered into a counter from the first card of'each group. Thereafter the entering of further group numbers into the counter was suppressed by means of group indicator contacts which opened up after the passage of the first card.

In the present machine the use of group indicator contacts is minimized. In place of entering group numbers upon a counter or counters the group number as taken from the card'is arranged to directly control the printing mechanism of the machine. The feature of suppressing the entering of items into the accumulator after the passage of the first card is obviated. Group numbers may or may not A cu be entered into 4the accumula-tor, but, if entered, these group numbers will be accumulated therein, there being no suppression of the accumulating of group numbers. 4

When this machine is used as a straight tabulator, without listing the items, it is run at a comparatively high speed but while the first card of each group is passing and the group number is being printed therefrom, provision is made for running the printing attachment at the usual (slow) printing or listing speed, otherwise the mechanism would be damaged. After the first card has passed and the group number has been printed the machine automatically .resumes its higher speed for tabulating the remaining cards of that group.

In connection with the printing of the group number in straight tabulating (nonlisting) operations provision is made for printing the group number upon the' record sheet only upon the passage of the first card group. Thereafter the 'normal paper feed is suppressed and when ultimately the total of that group is printed it is printed in alignment with the previously printed group number. Thereafter the normal paper feed is resumedto space the paper to position to receive the new group number imprint of the lnext group.

When the machine is set for listing, the

group number is printed concurrently with.

each listed item of that group. The group number is not repeated when printing totals of listed items. The printing of all totals is effected at proper printing speed by the reset motor.

Referring now to Figs. 13, 17 and 18, with the resistance controlled motor type of con- 316 shifted to listing position contacts X1.

will be opened and contacts X2 will be closed.

Fig. 18 shows other cooperating contacts which come into action when the shifter lever is in listing position. These contacts Z1 and Z2 are arranged to be both closed when the shifter lever is'in listing position and both opened whenthe shifter lever is in tabulating position.

Referring now to Figs. 24 and 25, shaft 355 which, as previouslyexpla'ined, rocks only during totaling operations, Vis provided with a depending insulating bail 355, which bail is arranged to normally hold open a number of non-list contacts NL1, N112, NL3, NL1 and NL5. Upon total-taking, shaft 355 lrocks clockwise (Fig. 24) and allows lall of these contacts to close. The purpose of these contacts is to close circuits to the printing magnets of the various individualcounters with which they cooperate and thereby allor a total to be printed of the amounts standing on such counters, except when such counters carry a summation of group numbers, inwhich case other means are provided for preventing the printing of such amounts.

1n the diagram, Figs. 26aand 26", the tab ulating motor TM is provided with a resistance 625 which can be manually adjusted by means of taps 626 to shunt out portions of the resistance as desired. l

Referring to Fig. 26at it will be noted that with contacts T1 and G13 both open the resistance 625 will be in the armaturev circuit of the motor TM. With such resistance in cir cuit with the armature the motor will rotate at a comparatively slow speed This is the speed which is used `for printing the group number from the first card. 1t is, however, desirable that all resistance be cut out of the armature circuit at starting to give the motor sufficient torque to start the machine. How this is done will be apparent from the diagram. The diagram shows the parts in condition for starting. Here cam contact T4 mounted in the cam boX of the tabulator is shown closed. This cam contact being in circuit between binder posts 16`and 17 cuts the resistance 625 entirely out of circuit and allows thetabulator motor to start with full current and full torque- Immediately after the motor has started cam contact T1 opens cutting resistance 625 into circuit. 1nasmuch as durin the first card cycle of a group cam contact 13 is open, themotor now continues in operation until the first card cycle is completed whereupon cam contact G13 closes, thus shunting resistance 625 again out of circuit and permitting the motor to operate at a high tabulating speed. Due to the fact that the current through the. motor is materially cut down for the first card cycle the current through the clutch magnet is so small that it does not hold its armature when contact C4 was made. To obviate this difficulty contact G11 is provided in circuit with cam contact C4. Cam contact G11 remains open during the first card tabulating cycle only and thus suppresses any action of cam contact C4 with respect to clutch magnet 55 during this card cycle. On subsequent card cycles after the group number is printed-cam contact G11 closes and is ineifectivepwith respect to cam contactC4.

Cam contact T1, opens av'short time before the end of the cycle and if running at normal speed the motor TM has sufficient momentum toA bring the kmachine to home or D position. With motor speed reduced as above forprinting this momentum is not sufficient to bring the tabulator parts to home position, if the tabulator is operating on one card group,- the only occasion -when thepmotor is called upon to stop while running slow under control of resistance. 625. 1n order to bring the tabulator to home position under these condithrough cam contactL4 through motor control relay contacts 130, through stop key contacts 87a and back to binder post 9. Cam contact L4B is arranged to make before cam contact T1 opens and to break at a slightly later point in the cycle thus'permitting the motor TM to continue in operation for a suliiciently longer period of time to enable it to reach home position when tabulating on one card group. Cam contact L1 is operated from listing shaft 294 which is in operation at all times when tabulating and listing or when printing the first group number.

1n the event that the tabulator is stopped by the emergency stop key 87 a when running at slow speed during the first card cycle it is desirable that means be provided for bringing the tabulator to home position. For this purpose a supplementary circuit 627 is providedextending to cam contact L4 and`connecting to a bottom contact of the emergency stop key 871. With emergency stop key depressed the tabulator will come to home position in the manner previously described.

' Referring now to Fig. 26a, contacts 250 are the usual transmission contacts (not shown) which are o ened when thetransmission 257 (Fig. 1)fis'1n high speed position for tabulating and which are only closed when the transmission is in low speed position for list- 1n0.

lContact X1 is in the circuit between binder posts 10 and 12 and this contact in addition to operating with contact 250 to compel the transmission to be shifted to slow speed position for listing also have other purposes now to be described. Contact 250 is in a line eX- tending from binder post 10 to binderpost 12 which also includes Contact Z1. VV'hen the list-non-list lever (Fig. 13) is shiftedfrom listing position to tabulating position or vice versa, there is a period of time in the shifting of such lever when both contacts X1 and Z1 will be opened. This opening of contacts X1 and Z1 during shifting operations is utilized to compel a resetting operation.l

Assume that the machine has been run with a listing setting and has stopped at the end of a card group the condition of the parts will be as shown in Fig. 6. If then the listvnon-list lever 316 is shifted the parts will assume the-position of Fig. 3. If now the machine were restarted on the next card group the Contact GI3 of the circuit diagram will not have reopened because there has been no intervening reset cycle to open them. Under such conditions the machine vwould restart and operate the listing mechanism under high tabulating speeds. To prevent such improper operation cert-ain circuit controlling connections are provided which will now be described.

Referring to the diagram, 84 is the magnet controlling motor relay contact 130. By providing means for deenergizing 84 during a shifting operation land by compelling a sub' sequent resetting operation of the machine before relay 84 can be reenergized, the aforesaid objectionable starting at high speed is prevented. Referring to the diagram, circuit circuit 628 is provided from the armature of relay 91 extending through cam contact P3 to one side of cam contact C1. The only way in which 84 and 91 can be energized is through wire 629 to binderv post 9, thence through binder post 10 to 12. By timing cam contact P3 so that this cam contact is open when the machine is in stopped position, and inasmuch as during shifting operations both contacts X1 and Z1 are opened at the same time there will be no path for current to How from left side of line through 84 and thus restarting of the machine will be prevented until current can be again applied to 84 after contact P3 is closed. Contact P3 is on total printing shaft 315 and is only operated during resetting and tota-l printing cycles.

Inasmuch as transmission 257 is used when straight listing is performed means must be provided for keeping resistance 625 from having any control of the mot-or during listing with the transmission shifted to listing position. Cam contact Z2 is employed for this purpose. This cam contact closes circuit Asame card cycle current would be 630 which extends to a wire 631 leading to group indicator controlling magnet .92. Thus when the list-non-list lever 316 is shifted to listing position cam contact Z2 will be closed, energizing 92 and causing contact G13 to be tripped and closed thus shunting out resistance 625. This contact will remain closed as long as listing continues and is only reopenedupon the next resetting operation. Then after it is reopened on the next resetting operation it is again immediately closed inasmuch as 92 remains energized.

As previously explained, when running under tabulating conditions contact GI3 closes after the first card cycle. The closing of this contact is effected by means of group indicator controlling magnet 92 being energized. This magnet when the machine is running under tabulating conditions has its circuit 631 closed by cam contact La which closes a circuit to G32 just at the end of the first card cycle. Cam contact Ls is on the listing shaft 294 of the machine.

Inasmuch as in printing the group number from the first card of a group this group number is printed directly from the card, provision must be made for supplying current to the printer magnets during this rst vcard group printing cycle of the machine. Referring to Fig. 21 contact GIS, as previously explained, is made for the first card cycle and breaks thereafter, being retained broken until a new group is tabulated. This contact as shown in Fig. 26b is in a line 633 extending between binder post 13 and binder post 8. The purpose of contact G18 is to supply current to the printer magnets which are correlated with the counter magnets if it is desired to group indicate on the columns in the printing section of the machine which are coordinated with the counters. In Fig. 26b 102 are the printer magnets. These printer magnets are connected to common bars 116. Bars 116 through wires 104 connect to the non-list contacts NL1, NL2 and NL3, etc. Contacts N 1, 2 and 3, etc., as previously explained, are open at all times except when a total is printed. Therefore with these contacts open it would be impossible to print the group numbers on the printer mechanism corresponding to these particular counters. If it is desired to print the group number on the field of the record corresponding to, say, bank N o. 3, a switch 634 would be iirst closed around the non-list contacts N L1. With this switchl closed during the first card cycle and with contact GIs closed during the supplied to common bars 116 from binder post 13, contact G18, wires 633, upper contacts P1 now closed, line 635, contact Ll)1 now closed, through switch 634 to common bar 116. In this way the magnets 102 are provided with a return path for the current which, as will be understood, is a secondary circuit which has been completed by the energiation of counter magnets from the brushes and the subsequent closing of contact 100. This counter magnet circuit will be traced for one column from left side of line, wire 82, through wire 101, contact 99, counter magnet 98 to plug socket 69, thence by plug connection to plug socket 68, thcnc(` through wire 65 to lower brushes. `When an index point perforation passes the lower brushes 59 current flows through these brushes, wire 95, cam contacts T2, T3, to binder post 13, wire 94, lower contacts P* now closed, binder post 11, through wire 636, to lower card. lever contacts 64",' to the relay point of relay 85, thence to cam contact T1, to binder post 9, through P5, binder post 10, contact X1, to binder post 12 on other side of line 83. The energization of magnet 98 closes contacts 100 and sets up a supplemental printing circuit as follows: from left side of line 82, through 101, contacts 100, printer magnet 102, common bar 116, wire 104, nonlist switch 634, and through the circuit previously traced through GIB to left side of line. It will be understood that switches 634 are only closed on the particular bank which is to be used for printing group numbers. If the tabulator is set for listing all the switches 634 will be closed on all banks in which it is desired to list individual items. The same l-applies if particular banks are to be used for indicating group numbers whenlisting. If it is desired to print only totals on particular banks, corresponding switches 634 can be opened. If the machine is set for listing, contacts X2, which are closed with such a setting of the list-non-list lever, complete the circuit to the printer magnets atvall times, acting similarly to contact G18 except that it does not open up after the first card cycle.

Contacts LPl, LP2, LPS, etc., are driven and actuated by or from total printing shaft 315 (Fig. 5) The purpose of these contacts is to break the circuit to the printing magnets at the end of the printing part of the reset cycle. They function similarly to contact-s P2 and P3 in the Lake application above referred to. Upper contact P2 whose cam is on the total printing shaft 315 is used to prevent certain objectionable back circuits during the total print cycle. The upper contact opens at the beginning of a total print cycle and closes at the end of such cycle. The lower cam contact P2 closes at the beginning of the total print cycle and opens at the end of the cycle. During total printing, current to the printing magnets 102 is supplied from right side of line 83, through non-total print switch 237, which switch has previously been closed. If it is desired to suppress the printing of totals non-total print switch 237 is opened. If a particular bank of the machine correlated to a counter is used for printing group numbers it will be understood that those group numbers will be accumulated in that counter. Obviously it is not usually desirable to print an accumulation of group numbers. Therefore, if group numbers have been indicated on a. particular counter bank, after the group has been completed, it is necessary that the accumulated group number be not printed. T his is effected by merely opening up zero button contact 128 by Zero button lever 129. With zero button shifted the counter will not be cleared but neither will the accumulated group number be printed. Before this particular counter can subsequently be used for accumulating purposes it is necessary t-o lclear out the accumulation on group numbers from the particular counter. This is done by a resetting operation prior to which resetting the switch 237` is first opened to prevent the accumulation of group numbers from being printed on the record sheet. In the embodiment of the circuit diagram shown in Fig. 26a the lower card lever contacts 64"L and 63 correspond to card lever contacts 64 and 63 in the previous Lake application heretofore referred to with the exception that they are both operated from the lower card lever in place of operating one from the upperand one from the lower as heretofore. The purpose of lower card lever contacts 63a arid 64a is to keep the machine running so long as cards are passing through the machine. The purpose of the single upper cardlever Contact 63b which is in one of the branches 7 4 of the automatic control circuit is to open the control circuit 7 4 after the passage of the last card through the upper brushes. This will insure that the cam contact L4 properly comes into action to bring the'machine to the D (home) position. As previously explained Ll is only operated to bring the machine to home or D position when fthe relays 91 and 84 (which'control contacts "130) are deenergized. With the last group. consisting of a single card, relay 91 woul be held energized if contact 63b were not provided. This contact under these conditions` will open and deenergize 91 allowing L4 to function in a proper manner.

Cam contact T5 is vopened at D position and is closed at all other times in the tabulating cycle. This contact entirely cuts olf the current to the upper brushes whereby they preios vent blowing of fuses during plugging opin alignment with said card group designations on said record sheet.
