AUTOMATICALLY-CONTROLLED TAIBULATING MACHINE.

Application filed December 30, 1921, Serial No. 525,954.

' To all whom it may concern: 7

Be it known that I, CLAIR D. LAKE, a

citizen of theUnited States of America, re-

' siding at Binghamton, in the county of a fu clear, and exact description.

This invention relates to tabiilating machines. More specifically it relates to tabulating machines which may be employed to perform various functions, as will hereinafter appear. I

Tabulating machines have'been heretofore proposed in which a stop card or stop cards are relied upon automatically to stop the machine, or otherwise modify its operation. At the end of each series of cards of a .particular group a stop card was placed. The machines toward. which the present invention is directed relate to aclass in which control is secured directly fromindex points of the record cards themselves, such controlbeing efi'ected through automatic control devices. These automatic control devices are automaticallv called into actlon by change in such lndex points, which represent group designations or like data, and sogovern the operation of the machine as .to'

permit a reading to be taken preparatory to tabulating the succeeding card group.

@ne of the principal objects of the present invention is to efiect improvements in such automatic control devices and the tabulating machines of which they. form a part, to the end that they may be. made more flexible and adaptable to the varying demands of the art to which they relate. V

, Referring to the drawings, which illustrate somewhat diagrammatically what I now consider to be a preferred physical embodiment of the invention,

Fi 1 is a diagrammatic illustration of certain of the Working parts of a tabulating machine and circuit connections therefor, and

Fig. 2 is a diagrammatic View of the remainder of the machine, the circuit con- 'nections and certain mechanicalconnections of this figure being so illustrated as to join corresponding circuit connections and mechanical connectionsin Fig. 1, when the two figures are placed-side by side.

In the tabulating machine shown,10 designates a stack of record cards which are fed one by one by means of a picker-'11 to suitable upper feed rolls 12 whence the cards are successively advanced thrrough intermediate and lower rolls 13 and 14, to the discharge stack, not shOWn. The rolls and picker are all driven in unison by the gearing shown diagrammatically in Fig. The

drive to. this gearing is secured through a shaft 15 which extends to the main tabulator clutch 16 (Fig. 2). This clutch is magnetically controlled by magnet 17, which when energized couples the card feed devices with the tabulator motor 18. Rotating in unison with the' card feed devices is a main tabulator register shaft 19. This shaft is driven in any suitable manner from the gearing which rotates the feed rolls. Also geared to the feed is a contact cam shaft 20. 1

From the register shaft 19, gearing 24 drives the clutch shafts 25, there being an independent clutch shaft for each register.

The registers are of the well knownHollerith type, and inasmuch as each register includes a number of wheels and controlling magnets which are identical, only one section needbe described. Upon the clutch shaft 25 are clutch disks 28 having fixed thereto gears 29 which enmesh with gears fixed to each counter whee1'.30. In order to rotate the counter wheels, clutches '31 are provided which are mountedto rotate in unison with the clutch shaft and are slidable nets 32 the armatures' of which engage clutch elements 31.

The energization of the countermagnets is controlled by'the index-point perforations of the record cards in a manner now well known to those skiIled in the art. example Hollerith United States Patent No.

In the diagram no disclosure has been (See for made of transfer devices, since these are of the type well known in. the art, and their illustration would involve. mere surplusage. Such transfer devices may be of the type disclosedin the United States patent t'oI-Iollerith, No. 974,272.

Resetting of the counter wheels is effected the counter wheel by means of a reset motor 33. This motor, through suitable gearing and magnetlcally controlled clutch 129, drives a reset shaft 34 which extends across the counters and drives same by means of individual gear sets 36 which are selectively clutched with the reset shaft. 34. These features are common and well known in tabulating machines and require no detailed description.

In order to simplify, illustration it may be stated that the drawings show one accumulating register or counter A, with wheel sections, and one register B which may be used for group indicating or ac- In practise both of d 49-50- respectively. As shown, the single cumulating operations. these registers will have more sections, an a plurality of accumulating registers will be provided. The magnets- 32 of register A are provided with the usual Holler ith relays 54, and from'these relays wires 55v lead to plug points 56. The group-designation or indi cator register B is provided with double point relays 57, and single polnt relays 58.

" The wires 59 which lead to the magnets 58 are branched as follows: one branch extending as shown in heavy lines through the flexible cable to'a slide block 60; the other branch extending to the plug point 61,

shown in Fig. 1.

sets of lower brushes 4144, carried by com- Referring now to Fig. 1 of the drawings: the'successive perforated record cards pass first between the upper and then through the lower.sets of brushes. There are two mon bar 42, and cooperating with cont-act blocks 43-45. The upper brushes 47 are carried by common bar 46, -a d cooperate with contact blocks 48. It Wlll be understood that the circuit from the brushes to the contact blocks is established when the index point perforations of the record cards pass under the brushes. The upper and lower brush sets 47-44 are for comparing group numbers or designations, and the lower set 41 are for'the item-numbers alone. In practise there are more than the three brushes shown in these various sets. From contact blocks 43 wires 51 extend to plug points 62.. These item plugs are usually connected by plug connections to the points 56 to control ,the operations of the accumulating counter A. It will be understood that there are more than three plug point positions 624-56, and these extra plugs will be used depending upon the number ofv columns in the card, and magnets in the counter or counters.

From the upper contact blocks 48, wires 49 extend to contact points 63. From the lower contact'blocks 45, wires 50 extend-to corresponding contact points 64. 'There is one point 63 for each upper brush position and a point 64 for each corresponding lower brush position. The slide member 60 is proshafts 35 to reset the 'plug sockets 67.

vided with cooperating contact points which make contact with points 6364 so as to permit a selected group of upper and'lower brushes to be connected with the groupdesignations or indicator register B. In the diagram, block 60 is shown provided with three pairs of connections so that connection can be established with any three pairs of contact points 63-64. In practise any desired number of these points can beprovided, depending upon the number of sections in the B register. The contact block 60 is also provided with individual switches 65 which, upon manipulation, are adapted to either selectively make or break the circuits to the upper and lower brush leads switch simultaneously makes or breaks these circuits in pairs The leads 50 which extend to the lower brush contact blocks 45 are also provided with extension leads .66 which extend to- 1 leads may be thus explained: the selected plugs 67 are coupled by plug connections to 56 permitting the group numbers which are being indicated on counter B to be accumu- The purpose of these lated on counter A or any other counter,

which may be provided but not here shown. These extension leads 66 provide particular utility also when only certain of the lower brushes connected to leads 50 are being used for group indicating. Those not used and not connected by slide block 60 to group indicating register B may be connectedup for accumulating on the A or simi-- lar register by means of the aforesaid plug connections. The operation may be best understood by considering no cards under the brushes, and the tabulator stationary.

Switch 7 0 leadingto the source of current supply is first closed thereby establishing the group indicatorcontrol circuit traced as follows: From binder post' C through wire 107 armature of relay 105, relay 108, and back to binder post I). By the energization of relay 108 the following group 1ndicator circuit is immediately completed traced as follows: From binder post G through wire 130, relay 110, wire 131 to armature of relay 108, thence through wire'132, 111, re-

lay 112, and through wire 113 to binder postf D. The energization of relay .110 is now maintained by two circuits: first through i the armature of relay 108 just described, and second through its own armature, wire 111, relay 112, wire 113 to binder post Group indicator counter control elay .112, now being energized, has attracted its armature 114 thereby making contact with individual wires leading to magnets 32 of counter B. This armature 114 maintains this connection with counter B until after passageof first card of a group of cards. The operator then depresses start key 71.

Current nowflows from source through binder post C, wire 72, relay-armature 73,- start key contacts 71, now closed, motor re-- clay 74, clutch magnet 17, tabulating motor 18, and back through wire 75 to binder post D, to source. It is necessaryto hold the start key depressed until the record cards feed into the machine and pass under supplementaryibrush 52 (Fig. '1), interrupting the circuit between the brush 52 and con tact block 53; The initial rotation of the motor has ,rotated contact cam shaft 20, and

allowed'cam contact .76 toclose a circuit per- V mitting "current to flow through line. 77,

cam contacts 76, 'to-binder post E. From this post E, wire 77 leads to the upper and lower common brush bars 4642. Until cards get under the .lower brushes it is necessary to preventthe energization of the counter. magnets .and relays controlled by the brushes. This control is secured by I means of the supplementary brush 52 which until cards pass under it allows current to flow from line 77 through 'wires 78 79, counter control relay 80, and back to binder post D. The energization of the relay 80 breaks the return circuit 81 of thevarious counter magnets andprevents the effective operation of the counters until relay 80 becomes tie-energized by a card passing under rbrush- 52. v The counter control relay 80 remains de-energized until the last card has passedyout of the machine. The operator holds down'start key 71 until a card is fed from the stack 10 down under, the lower supplementary controlling brush 52. This requires'afew card'cycles. At the begin- *nmg of-the'card cycle, cam contact device 76 will remake. -At this timecurrent flows from binder post C through wire. 77, cam contact device 76, binder post E, wire 82, armature, of circuit cut out relay 83,-w1re 84, relay 85', wi re 86, 'and back to source through binder post D. The energization ofrela'y 85 closes a circuit as follows: from I sourcerbinder post C, emergency stop key 87, binder post F, armature of relay 85 through motor control relays 8889, arma turef 91- of last .card control relay 90, departmentor. group indicator cutout circuit controlrelay 92 arm'ature93 of automatic lishes a holding circuit. for the motor relay -74 through ,wire 96. This lastmentioned stop control e ay ,94,. 'and back through line 95 to bin er post D. The armature of. relay 85 will release once per card, but the armature of relay 88 will have closed a holding circuit through 88,-891ete. This holding-circuit will be held until-achange in card group occurs when it will be interrupted in a manner to, be hereinafter described.- 'The energization of relay;89 est ab circuit maintains the motor in operation after the start key 71 is released.

As previously explained, when cards are,

thereby breaking the passing, relay 80 is deenergized allowing the return circuit from counter A to'be established through line 81. Counter A now accumulates items in the usual manner of the Hollerithcounter. Similarly ,magnet 80 -.when deenergized allows current to. flow through card counter magnet 97 which counts up cards in the usual manner. This card counter is controlled by camco ntact assembly 98 on shaft 20. Its registering counter is not herein shown as it is of the usual Hollerith type.

As is well known in these machines, the

group indicator counter is adapted to set up on the counter wheels the group number of-the-first passing card and thereafter-cut out the operation of the counter for the succeeding cards of the group. For 'fur-' ther descriptioncof this group indicator as previously used reference may be had to Hollerith Patent No 1,087,061, dated February 10, 1914. v l When utilizing counter B as a group or departmental counter,-cut out switch 99 is firstthrown to the right in the position shown; Relay magnet 92 having been previously energized, a circuit is established as follows: from binder post 0, through wire cult, armature. of rela' 108 is retracted,

rst holding circuit through 'lead'wire 132 to relays 110-112 which were energized, aspreviously explained. The'second remaining holding circuit to relays 110,112'must now be broken. I

This is accomplished by a cam device" 109 which is geared with the proper gearing to shaft 19' to make one revolution for each card passing the brush] After the first card."

"has been setup on counter B this cam device knocks 01f the armature of relay 110, a

and breaks the second or l'ast holding circuit of the department indicator circuit.-

When this relay 112' deener 'zed, by knocking off of the armature of rel y 110 by cam 109, the armature 1'14 will be'drawn upwardly, thereby breaking the individual circuits of the magnets 32, and preventing. back circuits as succeeding cardspass through the machine. is in the upper position it establishes counter cut-out circult 115 to the lower armature When armature 114 1,30

points of counter brush relays 57. The purposeof this circuit is to provide apath,

for current to flow when succeeding cards after the first card are passing through the tabulator. This is necessary since these succeeding cards are used for automatic controlling.

It will be noted that in. counter B, in ad dition to therelays 57, there are automatic to leads 50 and to the lower brushes. The

armature points of relays 58 on the other hand connect to circuit leads 116 which also extend through the sliding block60 as shown by the light lines therein, and eventually mutator is geared with the proper gearing of control on one column,

connect through leads 49 with the upper brushes. The establishment of the circuit from the upper brush, which circuit is known as the upper card control circuit, after pass ing through armature of relays 58, flows through a common line 117 to one brush cooperating with commutator 118. This com-.

with shaft 19 to make one revolution for each card passing the brush. It is provided with a plurality of conducting segments insulated from each other, each segment corresponding to one index point perforation on the card, and the segments are of such width, and brushes so adjusted that the time of the establishment of the circuit 117 by commutator is less than the time .of establishment of the circuit through upper 'brush 47 by the perforation or perforations- .in'the record card.' The circuit 117 from the commutator extends through a lead 118 to the armature ofupper card pircuit ,cut-out relay 119, thence through automatic stop control relay 94 through upper card circuit control relay 120, through department indicator' cut-out switch 99 to binder post D.

It may be-here stated (that as long as current does not 117-118, armature of relay 119 etc., the machine will continue to run, but when current flows in this circuit the operation of the tabulator will be interrupted, as will plained it is not permitted to be established flow through the circuit until sli htly laterin the card cycle, by reason of t e commutator 118. Therefore, by the time this circuit could be finally completed through the brushes and segment of the commutator, the relay 58 will have ating of this circuit. -Under these conditions the machine will continue to run since the cards are alike. in their controlling perforations It may be explained that this comparison of cards is effected by each two successive cards passing through the machine.

Assume now that cards under the upperv and lower brush have unlike perforations, say 8 and 9, the lower brush will make circuit 59 and energize relay 58. However, at

this time the circuit from the upper brush to lead 116 is incomplete since there is no perforation under the brush. The machine will continue to run since as previously explained this operation continues as long as curren g does notflowin the 117 circuit. However, when the 8 point goes under the upper brush there will be no current flowing through lower brush, consequently relay 58 is not energized, and a circuit is established'through wire 117 which controls the stopping of the machine. r

. The foregoing has explained the manner but it will be understood that the control can be effected upon a plurality of columns and a change of index point positions in any one of thesev columns will effect a stopping of the machine; The flow of current through 117- 11 8 to control the stoppage of the machine is only of short duration.- This'flow-bfcurrent actuates a number'of relays asfwill now be explained: 7

First relay 94 attracts armature 93, thereby deenergizing relays 92 .-89 88. The deenergization of 89 88 releases the armatures Which control the motor circuit through lead 96. The machine does not immediately stop upon .the deenergization 'of 8988, the motor circuit is maintained through wire 122, cam contacts 121, relay 74 until slightly before the so-called D posithe main clutch magnet 17, and cutting off fiow of current to motor18, thus stoppingthe machine at the so-called D position.

The flow of current through 117118 also energizes relay 120, attracting the armature thereof which establishes a holding circuit through relay 83, relay 123, and back to wire 102, cam contact device 101, wire 100 to binder post C. The energization of relay '83 attracts its armature interrupting circuit 845 to relay 85. The armature of this relay is then retracted thereby preventing the reestablishment of the circuits to motor control relays 88-89- after the index point has passed beyond the upper card brushes. Re-

tracted its armature and prevented the closlay magnet 123 when energized attracts its armature 73, thereby interrupting the circuit'72 to the start key 71. This prevents the restarting of the tabulator 'until the reading is'taken and the machine reset to 0, or the reset motor cycle completed. It may be here explained that it is not necessary to actually reset counters; to 0, but it-is necessary that reset should be initiated, and completed before the tabulating can be restarted.

The foregoing operation hasautomat ically interrupted the tabulating operation, brought the machine to a stop, and prevented the starting until certain further operations are performed. A reading is now taken of the counters of the tabulator. Such counters as are to be reset are coupled up to the resetting shaft 34 by means of the gears 36, and associated clutch device. The cam contact devices 101-125 are mounted upon the end of the reset shaft 34, and these cam contact devices are actuated once for each reset cycle. A' depression of reset key 124 will allow current to flow from source through binder post C, line 100, binder post R reset key 124, binder post R reset magnet 126, binder post B, through reset motor 33, binder post RF, back through wire 127 to hinder post D, and the current source. After depressing the reset key 124 it is possible to immediately release same since the energization of magnet 126 closes contacts 128, and allows current to continue to flow from binder post R ,'through contacts 128, R back to 126, etc.- At a slightly later point in the resetting cycle this circuit is taken over by can contact device 125 which short circuits the magnet 126,. and interrupts the reset motor circuit at the end of the reset cycle. The magnetically controlled clutch 129, which is of the usual one revolu tion type, insures the shaft 34 making exactly one revolution in resetting. The cam contact device 101 is so timed as to temporarily open 'just before the end of the reset cycle. These contacts arev thereafter immediately remade, and remain so at the completion of the reset cycle. The opening of these contacts serve to control a number of circuits as will now be explained.

' The opening of cam contact device 101 serves to interrupt circuit 102 which as previously explained extends to relays 12383- 94. The opening of this circuit deenergizes these relays allowing their armatures to fall back to position shown and permitting the restart of tabulating by depression of the start key in the manner heretofore explained. The deenergization of relay 83 allows its armature to drop back and permit the establishment of the circuits which control relays 8889 so that these latter relays can again be effective. The deenergization of circuit 102 by cam contacts 101 has the further function of deenergizing the holding relay 103, and relay 105 controlled thereby. .The deenergizationof relay 105 allows the armature to. retract thereby establishing the department indicator control circuit, which in turn establishes the department indicator circuit as previously described and relay '112 again connects department indicator counter I B for I registering the first car of a new group.

. Cam contact 76 operates in conjunction with cam contact device 76 to control-,cir-' cuits 77 to the brushes. These cam devices are common, and 'well known in tabulatingv machines of this type, and interrupt the circuit to these brushes at the completion of each adding cycle.

Relay has been previously mentioned,

but it has a further function in connection with control when the last card passes out of the tabulator. When thelastcard has passed the. lower brushes, supplementary brush 52 will establish contact with contact block 53, allowing current to flow through line 78 to relay 90, and back through relay 119 to binder post D. The energization of relay 90 attracts armature91, and interrupts the flow of current'through the control relays 88-89, thereby bringing the maoperation upon the passage of the last card from themachine. v r I I The emergency stop key 87 is in the return circuit from the main controlling relays 8889. The depression of the stop key 87 at any time will .bring' the tabulator to a stop at the end of the card cycle at the well known D position. After this stop key is operated the restart of the tabulator can-be secured by depressing start key 71 rovided the tabulator is not at the end 0 a card group where a total reading should be taken. Under these latter conditions the start key circuit will be interrupted by meansof the armature 73 of relay .123 as previously described. It will now be necessary to take a reading and eifect a resetting before the tabulator can be restarted upon the next card group.

When it is desiredvso to employ the machine that the tabulator will automatically restart upon the completion of the/resetting operation, the start key will have been closed ingot the tabulatorpreniaturely, is 7 revented by reason of the rela 123 which oes sirable to utilize the machine as a straight be seen that I have provided a tabulating .tabulator, and sup ress the automatic control and grou in icating operation. This is efiected by throwing de artment indicator cut-out switch 99 to the eft hand position. When switch 99 is thrown to left hand jposition .a circuit is establishedfrom binder post 0, through wire 134, switch 99, wire 132, wire lll grelay' 112,- and back through wire 113 to blnder post D- This maintains relay 112 ene ized at all times and permits the accumulating of items .on counter B. When switch 99 is thrown to'the left the up r card control circuit through relays 94:12 0 etc. is interrupted so thatirrespective of the .closure of the eontrol circuit at the upper brush there will be no automatic control of the tabulator.

In view of the foregoing disclosure it will machine in which the automatic control de 1 vices so govern the operation of the machine as to permit/the total or'accumulation of a card group, or-other tabulated card data, to be taken at .the end of a card group. fIn the specific form of invention -disclosed, the

automatic control devices exercise their gov.-

erning function by interrupting the tabulating operation. The machine comp-rises also means for resetting the tabulator wheels and for subsequently initiating, either manually or automatically, at will, restarting of the tabulating operation upon the succeeding card group. Provisions are included Whereby group numbers are designatedjso that the operator is apprised of the particular jcard group, or groups, upon which the autoillustrated, one may be used for group-dos matic control devices are operating, or have operated. Of the two counters or registers ignating and controlling, and the other for employed for accumulating; or one counter may be em loyed for group-designatingand the other or accumulating the group numbers designated by the. first. It will be noted further that the, automatic control ma be effected from different groups, selectab e at will, of a number of columns of index points of the cards,and that, in addition, one or more columns of any selected group may be suppressed at will."

Other advantages willnow be apparent in view of the disclosure and need not be enumerated. v
