UNITED STATES PATENT OFFICE PAPER FEEDING MECHANISM Jonas E. Dayger, Binghamton, and Edwin M: Hollis, Owego, N. Y., assignors to International Business Machines Corporation, New Yorki; N. Y., a corporation of New York Application September 25, 1948, Serial No. 51,282

Claims.

This invention relates generally to record feeding devices and more particularly to the automatic control of dual feeding devices so that selected items of a printed record such as a bill form are duplicated on a register sheet.

An object of the invention is to provide an improved dual feeding arrangement to effect duplication of certain recorded account information such as accounts in arrears, and to avoid duplicated recordings of other accounts such as ordinary paid up accounts.

Another object of the invention' is the provision of a common driver and separate clutching connections to dual pin feed shafts to call in the advancing means of an original strip and a duplicate strip under control of perforated records. As shown, each group of cards'of an account in arrears is preceded by an arrears signal card which serves to operate connections for clutching the duplicate strip drive to the main drive, whereby copies of only arrears recordings are made. Since the register strip ordinarily remains stationary under the bill strip and the carbon, all impressions are made on the register However, all such impressions made on the register strip while its drive is declutched are ineffective because the strip is preprinted with blackened horizontal stripes which are spaced to agree with the height of the bill forms and be presented at the printing line when the strips are in the home position.

Another object of the invention is the provision of dual record strips adapted for selective duplication wherein the duplicate strip is preprinted with a regular series of darkened horizontal areas agreeing in position with the division of the original strip into forms.

Another object of the invention is the provision of novel overfiow detecting devices for stopping the machine when items presented extend beyond one fonn length.

Another object of the invention is the provision of means for not only selecting the clutching of a second drive to move a second or duplicate sheet in synchronism with a first sheet, but also to select the starting point of clutching so that the second drive is brought into synchronism with the first. An X perforation in a special signal card is sensed by devices which control a stopping position such that the separate clutch parts of the two drives are brought opposite each other in clutching position. Other devices sense the same perforation to prepare to energize a clutch magnet to connect the two feed devices when they are in the home position.

This device is an improvement on the paper feeding mechanism shown in Daly Patent No. 2,348,059 issued on May 2, 1944 and reference may' be made thereto for construction and operation in general. In the patent the register strip received all impressions in a condensed form and was advanced by line spacing. In the present case, the register strip receives only selected data and is advanced by clutching its feeding means to the driver of the original or bill strip.

Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawin'gs, which disclose, by way of example, the principle of the invention and the best mode, which has been contemplated, of applying that principle.

In the drawings:

Fig. 1 shows a sample group of cards of an account in arrears.

Fig. 2 shows a portion of the bill strip or original record which is divided into forms one of which is illustrated.

Fig. 3 shows a portion of the register strip or duplicate sheet which is also divided into forms with dark bands separating them.

Fig. 4 is a front elevation view of the drive gearing, clutch mechanisms and stop emitter.

Fig. 5 is a side elevation view of the stop emitter.

Fig. 6 is a plan view of the drive motor and gearing, and the stop emitter in section.

Fig. 7 is a sectional elevation view taken along line 1 in Fig. 4 and showing the clutch mechanism for connecting the register strip drive to the bill form' drive.

Fig. 8 is a timing chart.

Figs. 9a, 9b, 9c and 9d taken together form a wiring diagram of the electrical controls of the dual feeding devices as coordinated with parts of a tabulator.

In Fig. 1 is shown one group of perforated control cards the leading card of which is an arrears signal card with an X perforation 2 denoting a group which is to be singled out for duplicate recording on the register strip. It is understood that the illustrative set of six cards is but one of a series of such groups, some of which relate to accounts in arrears and others not. Such groups are distinguished from each other by group control number perforations and thus total cycles are taken automatically and a bill strip is advanced from form to form as explained in Daly Patent No. 2,348,059. In the same column that the X perforation is found on the signal card, the other cardshave code number ateaesa perforations for selectively stopping the bill and register strip feed to place the record materials in predetermined line pcsitions to receive the impressions of name, address, bill address, items, totals, etc. wherever desired.

The record materials consist of a file sheet or register strip 1B, Fig. 3, and an original strip 11, Fig. 2, with bill forms. Both materials are continuous strips, but the bill strip is provided with weakened lines E2 which adapt sections ofvthe strip to be divided into separate. bills which.

are sent to the customers. The register strip 111,' Fig. 3, is the file Sheet which receives` the same impressions made on certain of the bill' forms, for example the arrears forms.

Both strips are drawn from supply hoppers behind the machine and advanced forwardly and upwardly around the platen 15, Fig. 4. The register strip is the inner sheet in direct contact with the platen and it has marginal perforations enga-ged by the pinsoffa pair of' pin feed Wheels 81 on a shaft 88. Bill strip i I is theouter sheet and is drawn over the stripv 1 e, on the platenv and it also has marginal perfora'tions and-.isengaged' by thepin feed Wheels 3.0 on-the feed shaft 82'.. Therefore, both strips are, guidedso as to partially surround. the platenV 13 at thev printing line'Z and then be directed. upwardly andV real'- wardly beneath adjustable'guide plates.

Adjacent the. bill; form is av conventional,A inking. r-ibbonzR so disposedthat when the differentialy adjusted type bars lf'are struck by-hammers to effect the printing` impressicn', the imprint will'` be'made on the bill form` 11. For providing carbon imprints of. such impressions on the. register strip, a carbon sheet may beinterleaved between the strips 10 and 1| or it may,` be. provided by a carbon coating on the underside of strip 1 1'.

In order to eliminate or make ineffectiye the carbonimpressions on the register str-ipwhen. it isheld stationary,

Stripes' or bands 9 which are spaced on the. strip to agree with the spacing of: the bill forms.

the register strip 1d is positioned so that the horizontal center line of a dark'band 9 coincides with the printing line at the platen. Thercfore, all impressions` made on ordinary bills are not recorded on the register strip, because the impressions are obscuredon the stationary dark receiving area. It is only when the drive for the` register strip thatl the light area'of the register strip moves up to the printing line and receives impressions which are duplications of the recordings on' a particular bill as shown in Figs. 2 and '3.

When a total is recorded at the bottom' of a bill form and related register strip portion, the register strip is advanced to bring the center of the next dark band to the printing line whilethe bill strip is advanced to a new form.

The bill strip is advanced by a separate feed drive motor through a train of gears and a magnetic clutching mechanism, the latterV having electrical commutator controls so that the bill form may be advanced to predetermined positions for the address, item and total lines.

The driving motor 115, Fig. 6, drives a pinion the zero point on strip It, Fig. 3, is preprinted or marked with darkened orV black horizontalV In, other words, there is a series of such darkened is clutched to the bill feed drive- 116 meshing with gear 1 1 '1, and to said gear is secured a pinion 119 driving a gear 120. To the gear 120 is attached a pinion 122 which drives a gear 123 secured to a shaft 124, Fig. 5. Attached to the shaft 124 is a ratchet clutch element 125. Since motor 115 is in continuous operation, the ratchet wheel 125 is also. rotated oonstantly.

The clutch mechanism is of a special design which enables a differential extent of movement of the pinfeed mechanism for the bill form and will now be described in detail. The electromagnetic control for the clutch consists of a startV magnet 121i` and a stop magnet 12'1, the .energization ofr the' start magnet 126 attracting .'an armature latch member 123 to release the clutch and the, stop'magnet 12'1 reversely attracting the armature latch member 121 to disengage the clutch. To further hold the parts of the clutch in normalposition and to prevent retrograde movement there; is; provided' 'a' detent magnet. 1729- with: an: associated latcharmatura` 136.

Loosely mountedv upon= the shaft 12.4' is. an: as'- sembly which; cornm'isesl a' gear-'130. (Fig. 6)", a spacing diskz13z1, and'aclutch disk 132i Mounted adjacentthe disk 132: is a similarly'shapeddisk 133 pivoted on the-shaft? 124 but.rotatable independently of the'disk'132; Eacha of thedisks; 1132-. and 1.33 have external. detent projections '1134: and in the normal position; of' thel parts the: aligned projeotions 1:324 of the disks' 13-3. and. 132 are; held' |by the;A crosszplate; 1 35 of the latch:a-rmature 1.-28'. The armature; 13.6- of; the detent mag net: 1.29: is' urgedV byl a spring: .13'1 so: that' it; in turn, cooperates' with: other a'ligned projectionsz 134: of the disks 13.'2L'and'l133=inthenormalposition'ofl theparts;`

To thedisk' 132l` therelis' attached= a spring stud" 138i and' to the detent disk 1533 thereis' attached* a spring stud'- 139A and a normally tensioneds spring 1411is-'fastenedlto'eaoh stud 13B' and* 1'39' so that since the-detent disks 1'32fiand= 133- are independently rotatable, it will' be-observed that energization' of the start magnet 1-26 causes the armature latchl 128 to' be drawn outwardly to disengage it from' the alignedpair of' projections' 134 of' the disks' 1-32 and 1733,' enabling' the normally tensioned springv 140 to rock the detent disk 133 slightlyy clockwise. This takes place be'- cause of the fact that the1detentdisk'132 is'now held' immovabl'eby' the trainof mechanism from such disk which overcomes the force. of the spring 140 so that the; resulting action is,V to rock the detent" disk 133slight1y'clockwise. Attached to the detentdisk: 133, is a disk |41whichv is. notched to receive the rounded end'of' a lever 1.42 ,which is'pivot'ed upon astud 143 secured to the detentl disk 132;. Itl will` be seen that the stud 143 'passes through` an aperture 144 formedv in. the detent disk, 133. Attached to the lever l1142 is a clutchpawl 1'45. in. theplane of the clutch wheel 125. vObviously, the slight clockwise rotation of the: detent disk 133.' whenthe clutch is. released' will cause the disk, 141' tofrock the pawl 145 to engage a tooth ofthe clutch wheel 125, this ac:l tioln 'being assisted by a spring 148' attach'ed' to theclutchpawl 145;. In this mannerv the clutch is engaged and the detent disks 132, 133 rotatively'displaced relative to each other with the' projection 134 ofthe disk 133 slightly ahead in a clockwise direction of the projection 134 of1 thel amd-982 energized and is kept energized for a length of time which varies according to the'different extent of movement given to the driven members of the clutch. When the driven member of the clutch has been given a predetermined extent of rotation in a clockwise direction, the stop magnet 12'1 is energized by means of electrical controls to be later described and at this time the start magnet 126 is deenergized as well as the detent magnet 129. Hence, the latch member 128 will be prositively drawn to the right so as to engage one of the projections 134 of the disks 132 and 133. The first one to be engaged due to the-relative displacement of, such detent disks 132 and 133 is the projection 134 of the disk 133 and this will be engaged by the cross plate 135 on the latch member 128, thereby holding the detent disk 133 and the member 141. The tooth of the'ratchet clutch disk 125 is still engaged with the clutch pawl 145 and this will rotate the disk 132"clockwise independent of the disk 133, but sinc'e the member 141 is now stationary the resulting action is to rock the latch pawl! 45 slightly clockwise to disengage it from the ratchet clutch disk 125 and at this time the projection 134 of the disk 132 will be engaged by the cross plate 135 of the latch member 128. At the same time, the armature 136 of the detent magnet 129 will engageupwardly over the projections 134 of the disks 132 and 133, and rotation of the driven member of the clutch will have been terminated and effecfed in a diiferential manner.

The driving connections from the aforementioned clutch to the pin feed mechanism for feeding the bill form are shown in Figs. 4 and 6. It will be noted that the driven pinion 138, Fig. 6, of the clutch meshes With a gear 151! which is secured to a shaft 151. The shaft 151 has a coupling connection 152 With the shaft 82 which is the pin feed drive shaft for the bill form; bviously, the differential rotation of the shaft 82 will, through associated pin feed Wheels 88, drive the bill form to the predetermined extent.

Of the electrical controls for determining the extent of the feed of the bill form, one consists of a commutator arrangement best shown in Figs. and 6. In general, the driven member of the clutch drives a rotating brush assembly of a commutator which includes the brush assembly, a common conductor ring and commutator spots or segments. This unit is known as the stop emitt'er or commutator. The pin feed driving mechanism for advancing the bill form is directly geared to the brush assembly and operates in synchronism therewith. The commutator segments are S0 arranged that each spaced segment represents a printing line of the bill form and each time the brush assembly passes a commutator segment, the bill form advances one line and does so until a commutator segment which is rendered effective for Circuit connections is engaged by the brush assembly, and as will be subsequently pointed out this stops the feeding of the bill form. From Fig. 6 it will be observed that to the shaft 151 there is secured a gear 155 having internal gear teeth 156 which mesh with a pinion 15'1 loosely mounted upon a stud carried by the frame plate 158. The pinion 15'1 meshes with a gear 159 which is attached to a stud shaft 168 rotatably mounted in a bearing 161 carried by the side frame 153. The brush assembly consists of a holder 162 attached to stud shaft 168 and carrying brushes 183 and 164 which contact with commutator spots or segments 165 and the common conductor ring 166. Obviously by the above ar- 6 rangement the brush assembly is driven synchronously with the driven member of the clutch and the bill form pin feed mechanism.

The pin wheel drive for the register strip is selectively connected to the bill form feeding means. For this purpose a clutch is provided between shafts 82 and 88, Fig. 7, the former being the shaft carrying the upper set of pin Wheels 68 and the latter being the shaft carrying the pin wheels 81. The train of gearing for driving the clutoh may be noted as follows:

Attached to shaft 82 is a gear 192 in mesh with a pinion 58 pivoted on screw stud 51 and integral with a gear 52. The last mentioned gear meshes with a gear '19 loosely pivoted on shaft 88, and gear '19 has fastened thereto a clutch disk 63. Ad- .iacent the disk and also'loosely mounted on shaft 88 is a plate 66 on which is pivoted a clutch pawl pivoted at 6'1. Along-"ide plate 66 and fastened thereto is a gear 55 also loosely mounted on shaft 88. Gear 55 meshes with gear 53 which is one of a pair of idler gears pivoted on a stud 54. The other gear '18 of the pair meshes With a gear 84 fastened to shaft 88. The two gears '19 and 84 are similar in size and appear as one, in Fig. '7. By means of the train of gearing it is arranged so that shaft 88 makes one revolution per bill form and therefore the clutch is of the single tooth variety With the tooth of the pawl engaging in single notch 64 of disk 63 whenever the clutch is tripped for duplicating purposes.

A spring 68 tends to engage the pawl With the clutch disk but the pawl is normally held out by the hooked end 61 of a release lever 58 which is pivoted on stud 60, Coupled to lever 59 is a restoring arm '19 with a spring '11 pulling between the two so that the upper shouldered end of lever 59 abuts against an armature lever 58 pivoted at 56 and pulled away from register feed magnet RM by a spring 5'1.

W henever the magnet RM is energized to clutch the register strip pin wheel shaft 88 to the drive shaft 82 of the bill forms, lever 58 is attracted and rock'ed counterclockwise and the lower end is raised above the shoulder '14 thus freeing lever 59 to be rocked counterclockwise to release pawl 65. When released, pawl 65 is rocked clockwise by spring 68 and the tooth of the pawl is dropped into the notch 64 to key the shaft 88 to the rotating disk 63 for one or more revolutions. Thus, the register strip is advanced with the bill form for one or more selected bill printing cycles to print duplications of special account forms such as accounts in arrears.

Restoration of release lever 59 is accomplished by a lug 83 on the side of gear '19. The lug Strikes the under side of the end of arm '16, rocking it clockwise and carrying lever 59 along therewith to shift shoulder '14 to the right of the end of armature lever 58. This relieves the pressure of the lever 59 against the armature 58 and leaves it free to be tripped. If magnet RM has been deenergized then lever 58 will drop behind shoulder '14, if not, then it is a sign that two bill forms are to be duplicated, and lever 58 remains lifted and lever 59 swings back counterclockwise to leave pawl 65 connected to the disk.

When the hooked end 61 swings up into restoring position and stays there, then as the pawl comes into the home position the short arm is engaged and the pawl is rocked counterclock- Wise and disengaged from the disk to stop the register strip feed. A rebound preventing lever '15 is loosely pivoted alongside lever 59 and pulled 7. byspring' 62 to snap behind the shortV pawl Varrn: and prevent vibrationas the pawl is disengaged';

The foregoing Sections ofV the description deal mainly with the mechanismof the machinel and the` parts about to bev considered relate more to the electrical controls and the Wiring shown in Figs. 9a 9d.

At the top of Fg. 9a it is seen that'in addition to the usual power supply" switch, av dual car'- riage switch SWIA is provided to-connect the carriage motor ll between the two main lines.. 182 and 183. For. purposes of -i1lustration, all other controls are shown wired between the'l two lines.

As a preliminary. to the proper. placement of printing lines on the forms, the stop emitter or commutator should start at thezero position as indicated by the pointer |80, Fig. 5. With. the' emitter properly. located the bill forms .can be assembled on the pin Wheels withthe start positions at the printingline and' proper feeding will then ensue. I It may be possible that the emitter isrnot Vat the zero position in which case ,a reset key |8i (Fig; 9a) is. depressed and a circuit Will be made from the line |82 to the line 183 through contacts closed by the reset key |8| to energize the pickup coil of a relay DF22. Relay coil DF22 like many others is a dual-wound relay which consists of a pickup coil and a holding'coil which are respectivelyidesignated P and I-Lrwhichdesignation is also made foriother similar coils. The, holding coil of relay DFZZ or DF22 (H) will be picked up by contacts DF22c, a stick circuit for DF22 (H) then extending back to the line |82 through such contacts and relay contacts DFZb now closed. Hence, depression of the reset key |8| will cause the energization and maintained energization of relay coil DFZZ which will transfer' its contacts DF22b' (Fig. 90) and close its contacts DF22a, DF22c and DFZZd'. I

The start circuit which provides an' electrical control whereby the clutch is` engaged' so that theV stop emitter may be reset to its zero position will now be described. The energizationof the relay coil DFZZ- closes its contacts DFZZd to thereby close the circuit from the line 182 through relay contacts DFZEJb, through relay contacts DFZZd, thencethrough A circuit breaker contacts (to-be subsequently'described) through relay coil DF23- to the line |83. A holding circuit'for the relay DR23. is, established through stick contacts DF23a; contacts DF22d, and contacts-DFZOb now closed, backV to line |82. Relay'coil DF23 will now.v close its' contacts DF23b so that'when the' B circuit breaker (to be subsequently describedlf closes; animpulse will be directed fromline |82, relaycontacts DFOb, the DF22d' contacts. now closed, the B circuit breakerfcontacts; through DF23by contacts to the. pickup windingV ofrrelay coil DF2I. The latter closes its contacts` DF'ZIa` to pick up and maintain relay coil DFZI (H)` energized by a circuit from line |8-3; relay coil DF2| (H), relay contacts DFZIa, and relay contacts DFZOb to line |82.

Theenergization of the' start relay-DF2I (H) will` close its contacts DF2 IdV so that'a circuitlwill be made from the line [82 through contacts DFZOb now closed, through contacts DF2|d now closed, thence through the-startmagnet |26' and also through the detent magnetlSV (both ofthese. being'held energized as longu as contactsv DFb are closed) and switch SWI to line |83'. The energization of bothV of these magnetswillcause the-'clutch to be engaged and the commutator wilL rotate. f rom; the position; in:. which`` itV is.. in; if

it is off' thev zero startingfposition, and wil'lzccn'-vv tinue.L until ,the commutator; brushesV I 63.' and [6,41 Fig;v 9a; are atthe.zero,positionat which time; a circuit willbe; closed from. the.` line |82j', wiref229; through thecommon conductor'ring |68, thence by" brushes. |63 and: 1.64 through the; 0: com', mutat'or. segment |65 and wire'/ l99, thence: through. relay contacts DF22b now: transferred; and wire .'2,03; Fig. 9a, to theV stop magnet |2'1,-'. This'sameimpulse is also directed to relay'coil DF20. and'the` latter opens its contacts DFZOb to thereby open therstick circuits for the holding: coi1s= of relays DFZ |,,DF22', relayv coil. DFZ'I'I',y start magnet |-26f and detent magnet |29. Obviously; when the zero position of the commutator' is reached, the energization ofthe: stop mag-net 1.21; will disengagethe clutch and'the' commutator will' remain` at'such normal starting,- position. "I`heprovision. of theW contacts DF22b, Fig. is: w cause; by'the'opening of its-right hand:contacts;` the ineffectiveness of the` plug-connectionslwhich may havebeen madeand which are' utilized t'o: cause. the energizationof: the stop magnet: |2Fl'.` when'v predetermined spacings off the' bill form areto be-made.v The opening of such-contacts; therefore', prevents such controlv when the: reset key 18| is depressed to zeroize the commutator.`

If resetkey |8| is helddepressed after'thefizerov position of the commutator has` beenreached-witr. the commutator 'brush on the insulating space be tweenf'O and 1, the continued'energizationof. relay DF22 will transfer itscontactsfDFlZ tozkeep relay DF20 energized, since a' stick or'energizing circuit for the latter is provided inthis-instanceby DFZOa contacts, DFZa contacts and? wirezZiH to'line |82'. As long'as DF2B'is kept energizedby. holding key |8l depressed its DFUb contactszare; open to preventv another impulse fromv beingfdif.A rected to relay DF23 to initiateV a: successionV of.: resettingcycles.

Therezwill now' be described inV connection. with' the. circuit diagram the mannerin which-.predef termined spacings of the bill form are efiectetv with the, normal operation of the tabulating machine -andunder control. of previously made plugging. connections.

The improvements are incorporated in the formv of.v tabulating machine shown in the patentto Peirce, No. 2,042,324, dated May. 26, 1936, and-the` patentto Mills, No. 2,079, 418, datedMay 4, 1937,- such a machine having a printing mechanism shown in the patent to Mills, No. 2,016,682, datedl October 8, 1935, which printingl mechanism is capable of? printing numerals and alphabetic characters.

The, tabulating machine is provided with a card. feeding mechanism which is shown in. Fig.,6 of the; Peirce patent, No. 2,042324 and cards. are successively passed through the machine, first to the upper' analyzing brushes and.thencetothev lower analyzing brushes so that for each cyclic operation of the machine after the first card cycle, a card passes the upper and lower analyz, ing'brushes'. concurrently, during which time operation of the-printing. mechanism occurs under controlof 'the card at the lower-brushes. Tabulating machines of this type, are provided with several one-revolution shafts which are adapted to carry cams. which open and close contacts; The present tabulating machine includes an additionalcam contact designated "PMGA shownin the circuit diagram of Fig. 9a and which has the timing for each total and item entering cycle shown in Fig. 8. It will be noted that this cam closes, its. contacts at approximately 243,o of the.

cycle and the print drive shaft 134 therefor is rotated one revolution for each operation of the printing mechanism. As will be made clearer llater on, cam contacts PMIA render the circuit breaker 185 operative at 243 of the tabulator print cycle. The circuit b'reaker 185 is driven by motor I and is not in any way mechanically operated by the tabulating machine.

In the present machine, the cards which are successively passed through the'machine comprise: First, a signal card in the case of arrears accounts, .then one or more successive address cards, which latter are followed by one or more item or detail cards. Upon the change in classification of the item cards a total is automatically taken as is well known and during such total taking Operations as will later be described in detail the bill form feeding operation is initiated after printing atotal and this initiates, with the plugging arrangement shown in i ie circuit diagram, Fig.

9b, the feeding of the bill form and stopping it at 'line 5 of the sheet shown in Fig. 2. Such plugging may be made in the presence or absence of lcode number perforation control of feeding which `has-independent control over the stopping positions of the stop emitter. During the next cyclic operation of the tabulating machine the name card now passes by the lower brushes and the printing mechanism is adjusted so as to print the name on line 5 of the bill form and through the carbon printing sheet upon the register sheet. During the cycle of operation in which the name is printed, cam contacts PMIA close at 243 after the printing operation so that a circuit is closed .from the line 182, Fig. 9a, through contacts PMA, thence through card lever relay contacts DFZa `and the pickup coil DFI '1 of a start control relay.

vAt the top of Fig. 9d therelay DF29 is seen to bev in parallel with the usual lower card lever relay R3 for Operating contacts throughout the tabulaton i Such card lever contacts are-provided in the machine to enable the circuit closure now being described only when cards are beneath the lower brushes land such form of card levers and associated contacts is well known. The relay DF1'1 not only operates its contactsDFl'la to put a stick circuit through its holding coil and closed contacts DFZIb, but it also has contacts DFllb in series with the A circuit breaker to call relay DF23 into operation. The latter closes its f contacts DFZa so that a stick circuit extends back through the relay contacts DFi'ib to line 182.v During the timethe relay coil DF23 is energized and its contacts DF'23b are closed, the B circuit ,breaker contacts close so as to extend the circuit from the relay contacts DFl'lb through the B circuit breaker contacts, thence through relay contacts DF23b to the pickup coil of start relay coil DFZ 1 Attention is also directed to the use of the two circuit breakers A and B. v The 'purpose of this arrangement is to provide a full and correctly timed start impulse to the start relay DF21 so that the clutch pawl 145 will engage a tooth of ratchet wheel 125 at the proper time. The two circuit breaker contacts A and B are shown in Fig. 5 and the commutator 185 therefor is secured to the stud shaft 121 which is driven by the driving motor 115. Contacts PMIA are located in the tabulator, and A and B circuit breaker'contacts are driven by motor 115 so that it is necessary to provide the correct timing of an impulse and this is effected by setting the ommutator of the circuit breakers.

As a prellminary to the start circuit through Vthe Hcircuit breaker contacts, relay contacts DFl'lb in series therewith must be closed in a manner about to be explained. Cam lcontacts PMI A are effective to call in startco-ntrol relay DFI'I either when a card is under 'the lower brushes as indicated by closure of relay contacts DF29a, or on the last card cycle When cards run out as indicated. Vby closure of relay contacts DF25a. Near -the top of Fig. 9a it is noted that contacts DF 9a, and DF2 5a are connected in parallel, but both are in series between relay DFH and camv contacts PMIA.

As already noted, relay DF29 is connected in parallel (Fig. 9d) With the usual lower card lever relay R3 and a's long as cards are under the lower brushes circuits will be established thereto.

Relay DF25 is called in by a minor group change and is held beyond the cycle in which the change is sensed and into the next card feed cycle which is useful to hold on run out cycles. As explained more fully hereinafter, a relay DF28 is energized by a minor group change. This relay DFZB has contacts DF28b in series with the pickup coil of relay DF2 5. The circuit for picking up relay DF25 includes line 183, Fig. 9a, relay DF25, contacts DFZBd, cam contacts C346, Wire 218 and line 182. Relay DFZS then closes contacts DF25a for a holdingcircuit and contacts DF! 5b for the operation of the start relay DFH on runout cycles. The holding circuit passes along line 183, holding coil DF25, contacts DF25a, Wire 2811, cam contacts CF52, Wire 225 and line 182. The start circuit includes line 183, relay DFI '1, either contacts DFZa or DFZSb, cam contacts PMIA and line 182. Relay DF1'1 then closes contacts DF1 "1a to prepare a holding circuit for a holding coil through the normally closed contacts DF21b of the main start relay DF21. The holding circuit includes line 183, relay DF1'1, contacts DFlla, relay contacts DFZlb and Wire 201 to line 182.

Summarizing the start conditions, it is noted that cam contacts PMIA close to call in relay DF1'1. The A circuit breaker contacts sense this condition and cause the energization of the interlock control relay DF23 and then when the B circuit breaker contacts close a correctly timed impulse will be sent to the start relay coil DFZ l.

Assuming that the desired synchronization has been obtained and start relay coil DF21 has been energized, the hold coil DF21 v(I-I) energizes through the closure of relay contacts DF21a, thel stick circuit for the hold coil being maintained through contacts DF21a and relay contacts DFZOb back to line 182. At the same time, an impulse will be sent by the closure of contacts DF21d to both the start magnet 126 and the detent magnet 12a thereby initiating the engagement of the clutch after printing the name on the bill form and register sheet. Since, in the previous total taking operation the sheet was advanced to line 5 of the bill form, the brush 'assembly of the commutator will advance to the next position and with the present plugging arrangement commutator segment 6 of the group of spots is effective to terminate feeding of the bill form after it has spaced one line, this being effected by circuits now to be described in detail.

When relay coil DF21 (P) is picked up by the circuit arrangement previously described, it Will close its stick contacts DFZI'a providing a stick circuit for DF21 (H) extending back'to line 182 through DF2 1a contacts and DFZb contacts now closed. It should be noted also that relay coil Ifl .zDFl :(H) will maintainrcontacts SDF2Ld closed, rthus causingdetentmagnet;129 and start magnet [26 :to `be 'retained energized by v.a ;circuit extend' ing back ;to line 1582 through .relay contacts DFZJd and *DFZflbu WhenmelayoilDE-'fl (H) Lis -energized ;it also clos'es 'its relayacontactsDFMc 'which :are :in 'theV stick 'circuit vof :relay DEM, the :stickcircuitfor relayfiDFn extendingfiba'ckto line .1.82 through relay contacts .DEflnazand DEzlc.

The cams controlling the card feed contacts-designated CF, of zwhichCFS and CF'2 are two, l are driven by ;a shaft 'which is :rotated during card 'feed 'Operations` shaft corresponds -ito the shaft 'designated 1385 in the :patent Vto lPeirce, No. 2,043,324 .in Fig. 4 thereof which shows similar CF -cams 'andfcon" -tacts.

During the tabulating machine cycle that the last address card controls to print the last line of the address, the clutch for the bill form spacing 'mechanism will b engaged in the manner previously dscribd and the brush assembly of the commutator will move from contact spot 'I to contact 'spot 8, etc., but since such contact points have'not been plugged for circuit connection it will be ineffective and the brush assembly will continue to move to make contact with contact point 12 and at this time the circuit will be closed from the line 182 through the commutator and extended by a plug connection 192 so that the circuit will be continued through contacts DF24c now transferred, thence through relay contacts DF22b and Wire 203, Fig. 9a, to the relay coil DF20 and the stop magnet 121. Thus, bill form spacing Operations will terminate when line 12 of the bill form has been presented to the printing line.

After this, successive item cards pass through the machine and by means of cross plug connections 193 the bill form is spaced line by line as the items represented by the item cards are printed. Such Operations Continue and in the present example five lines have been allocated for receiving such item imprints and these will vary with each customer's bill. When the last item card has passed by the upper brushes, the first name card for the succeeding bill passes by the upper brushes and automatic group control in the machine ensues in a well known manner. This control initiates total taking and total printing Operations and upon taking the total the bill form is spaced from the last printed line to line 20 in the present example so that the total may be printed on line 20 of the bill form.

The spacing of the bill form to line 20 in the present example is initiated by the well known auto groupv control. This form of control is a well known part of the tabulating machine in which the present improvements are incorporated and is fully shown and described in the aforementioned patent to Mills, No. 2,079,418, dated May 4, 1937. In general, the tabulating machine is provided with group control devices for sensing and comparing the group number perforations on successive cards under the upper and lower brushes. All of the name, address and item cards of each group are perforated to represent the same account number. Obviously, when the last item card such as an arrears card passes by the lower brushes the first name card of the succeeding group passes by the upper brushes and with the well known group control described in the aforementioned patent, a minor group control magnet designated MI in the above patent to Mills is energized.

In order that Operations to be subsequently explained are properly timed With the group control mechanism it is preferable to utilize in the present machine the group control circuits fully shown and described in the patent to D. W. Rubidge et al. 2,340,772, dated February 1, 1944. Recourse may be had to such disclosure'for a complete understanding of the group control mechanism but for convenience in reference, the group control circuits involved in the present machine are illustrated in Fig. 9c.

Referring to Fig. 9a, reference character 233 refers to the upper group control contacts and 23| designates the lower group control contacts. It is known that upon an agreement in perforations in the same cardcolumn of the cards at the upper and lower brushes, contacts 233 and 234 will be simultaneously shifted from normal position and will not close a circuit path. If either of the contacts 233 or 234 is transferred first and before the other contacts, the following circuit will be made: from line 183, through cam contacts CBI 1, through contacts 233 and 234, one of which is transferred and the other is at normal position,l thence through the pickup coil of relay coil R126 to line 182. Relay coil R126 closes its contacts R126a, picking up the hold coil of relay R126 through the stick contacts CB24. The hold coil of relay R126 will close its contacts R126b to pick up a relay coil R26 by a circuit from line 183 to cam contacts C319, pickup coil of relay R26, relay contacts R126b to the line 182. Hence, during 'the cycle in which a change in group designations is sensed, relay coil R26 will be energized. The pickup coil of relay R26 will close its contacts R260, closing a stick circuit from the line 183 through relay contacts R26c, the hold coil of relay R26, and cam contacts PM 15 to the line 182. Because of the timing of the PM15 contacts, relay coil R26 Will be energized for the remainder of the cycle in which a change in group designations is sensed and for a greater part of the next cycle, which is the total taking and total printing cycle. In the present machine a pair of relays DF32 and DF33 are connected to be operated as the ordinary group control relays are operated and correspond respectively to relays R126 and R26. There is also another relay DFZB shunted across relay R26. In effect the two dual feed control relays DF28 and DF33 have the same timing and action as the ordinary minor control relay R26, the difference being that the two have contacts in the special dual feed controls of the present invention as explained throughout this specification.

Relay DF28 closes contacts DF28d, Fig. 9a, to call in the pickup coil of another total control relay DF25 which is held operative longer than relay DF28. The pickup and holding circuits for relay DF25 are described hereinbefore with reference to action on the start controls and relay DF1`| by contacts DF2 5c in series therewith.

After the total has been printed the start circuit for engaging the clutch for spacing the bill form will be energized during the total taking cycle the same as in printing items, it being understood that contacts PMIA also close during the total taking cycle. The bill form will then be spaced from line 20 to the next commutator segment to which a plug connection has been made. By means of a plug connection such as Wire from the 5 spot the impulse is directed to the stop relay DFZ and the stop magnet 121 by the circuit connection previously described in detail. The next successive section of the bill form will now be in position for receiving the printing of the name of the next group.

It is also desirable that upon the passage of the last item card of the last group that the bill form be spaced from the total printing position to the next section and from the circuit diagram it will be observed that loWer card lever contacts R3a, Fig. 9d, would be open and relay DFZS deenergized upon the passage of the last card by the lower brushes. The transmission of the start impulse to the start control relay DF, Fig. 9a, and in turn to the start relay DF21 is effected under such circumstances through the clcsure of relay contacts DF25c instead of through card lever relay contacts DF'29a which are 'now open,

.15 Hence,1durlng the total taking operation for the last group the 'bill :form will =be spaced Lto line of the next bill form.

At `this point '-it is well -to point out A`a basic difierencelhetween the present machine :and the deiices lof`'fl31`al'y` .Patent No. 234850519. In Vthe feed control 'of the patent, the card ihad -no means 'of selecti-ng the extent of paper feeding advance. ln the present instance, :a column of perfora'tions in the cards is de-veted'to code perforati'ons lfor 'the selection of line positions on the bill -for-m. carria'ge plugfiboard (top `of Eig.v lSicf) -is'-provided which is used iso-select desired pesitions to ;stop the 'advance of 'the forms to receive address, item total lines in -predetermined places onthe forms. There .plughubs `(3-9 and X, IR `corre- -s-ponding .to all possible -perfor'ation positions in the line selection column of the cards; iOppos'it-e these are the ;G439 plughubs representingthe .line positions -of the stop- -emitter 155, I'GG, 'al-ready descri'bed. The additional fu'ncl'iion'ally` controllled pl'ughulbs Name, Body, Total (Minor, Inter. and' Major) and Line are 'arranged with transfer Vcontacts to-talre precedence over card 1co'i'itrolled ilin'e selection. The record feeding devices 'are started near the end of each tabulator'pri-ntng cyc-lev'and the feed isstopped by the emi-tter w'ithth-e emitter brushed between commutator spots- 165.

The line selection `feature provides means whereby each card by a code perforation ltherein is adapted to select the line of the bill 'form which is toZ receive the printed data of thev card. The bill and register strips will advance from any line to-any other lline in a forward d-irection. For example, if the cards are punched with line selection code holes 2, 3. and 6 Vand are fed in the order given, by plugging it. is possible to print the data fromzsuchcards on lines v5, 9 and 12-, respectively, on the bill form. In other words, the code hole' values need have no relationsh-ip to the line' `values, other than thatthey `are both in ascendin'gforder.

Inorer tov ill-ustrate the operation of line se-= lectionby a card exercising control over the stopemitter it-is believed best to take anexample-andtrace the' effects all the way through` A'ssumingthat the machine is in operation-,that some cards of. a group are already red and someI lines already printed on a bill form, andf a card isv advanced under theupper brushes UB with a 6" perforation in the line selection column. Also assume that the 6" pughub of the carriage plugboard, Fig. 9b, is connected by Wire 2M to the 1='2 spot 165: of' the stop emitter. Then the` following circu-it vconnectionsare made to exercise'feed' stoppage' alter printing.

As the card passes under the'upper brushes UB, there ismoved in synchronism therewith', the brushholder 2535, Fig. 9b; of a line selection emit-- ter LSE which is mounted on any card feed 'sha-ft. The brushefi; of emitter LSE move over common contact strip-72ml and spots Z'i in the order 9, 8, 7, etc. as the related perforation positions' of the .line column' pass under the plugged brush UB. When the GP postiion'is reached and a peri'orati'on cletected, then' a: circuit is estab-` lished. as follows: line U33; Fig. 9b, Wire 2l9` to' common roller and through card at'upper brushesand brush UB connected' to socket 208, a plug Wire to socket 9b, Wire 2| i, contact strip 236, brushes and brush holders 205, ''6 s.pot' 207; wire 2|2, pickup coil of rel'ay DF3`; Wire 2l3 and' line 182. A relay DF?` isa-lso picked up because it is in ,series with common str-ip 295' and a pair o'i'icain contactsl'lliil closed during the passage iii 16 of vthe 4 'to 9 lperioration poitions.

by brush UB connected to socket 208, a plug Wire to socket 209, Fig. 9b, Wire 2| I, contact ring 206, brush holder 205, "X spot 201, wire 231, spot 201, relay DF2 and line I82. Relay DF'I is not picked up'at this time because its timing is limited by cam contacts CFIA to the 4-9 positions.

Relay DF2 then holds and picks up relay DFS which is also held and closes its contacts DF9b (top of Fig. 9c) in series with normally closed contacts DFISb and the X socket which is plugged to the 2" spot I65 of the stop emitter,

By means of the foregoing connections, the carriage is stopped'at the "2 position after feeding is initiated on the idle total cycle by the pickup of relays DFI'I, DF23, DF2I and the start and detent magnets I2B and I29.

This stop by the emitter is not for printing purposes and occurs on an arrears group for spacing control and align'ed ciutching of the register strip.

Concurrent feeding of the register strip with the bill strip is also controlled by the uTX perforation 2 in the arrears signal card I. In other words, the signal card not only selects dual feeding by clutch operation but also selects the place for clutching of the duplicate feed devices. The arrears bill control hub 239, Fig. 9d, is plugged to the upper brush socket 208 along with the Dlugging to socket 209, Fig. 9b, already described.

The clutch operation initiating circuit includes line I83, Fig. 9d, Wire `2I0, through the common roller and signal card "X" hole, and brush UB of the line selection column, socket 208, a Wire to socket 239, cam contacts CBIA closed at the X time, pickup coil DFIB and line I82. Relay DFIB is held through contacts DFIIia. and CFZA until the next card feed cycle. Relay DFI'B also closes contacts DFIBb to pick up control relay DFI9 by the circuit: line I83, Wire 240, relay contacts Relay DFI9 is held by its own contacts DFI9a in series With contacts DF33b which hold until there is a change of card groups.

Relay DFI9 also closes contacts DFI'Sb, Fig. 9a, in series With the register strip clutch magnet RM. This causes release of the clutch pawl S5, Fig. 7, and engagement of the nctch of. disk 63 at about the 2 spot position on the stop emitter and the register strip is then ready to be 18 advanced in step With the bill to dulicate' the arrears account and be disengaged only ongth next unequal impulse or group change action on relay DF33 marking the end of the billing group.

The carriage is now standing at the 2nd li'n and is advanced to the next hot stop iittif spot by av list cycle While feeding' the signal card through vthe lower brushes at which time the ad= dress card is feeding under the upper brushes; Since' a *'2 Was assumed punched in the liii selecting column of the address card, and since the "2 socket 24|, Fig. 90, is plugged to the 5,5 line spot IB5, the feed devices Will stop accord= ingly.

The 2" is sensed in the line space emitter L'SE, Fig. 9b, and relays DF5 and DFI2 are picked up and held. The setup of the circuit for holding relay DFI 2 is such that it is held for two printing cycles through the cam contacts CF52, Fig.. 9d.

At the time the address card is fed into th lower set of brushes for first line printing,- theI meter address card is fed through the 'upper brushes and stops between zero andone. However, the meter address card is punched "3 and this line selection code number must be sensed and stored for future use Without interfering With the 2" line selection control in effect at the time. This is accomplished by relay contacts DF3'8b, Fig. 9a, which are in series With Wire 220, Fig. 9b, and the readout pickup coils of relays DFB-DFIII to prevent them frombeing energized until the picker knife contacts PK2, Fig. 9d, close in series With relay DF38 indicating that the second address card is being advanced down from the upper brushes. i

After the addresses are prnted, the detail cards uConsumption," "Merchandise" and uArrearsj' are fed in, and the "6 line selection perforations therein are plugged to select lines 12, etc., on the record materials.

Assuming that there are ten detail cards instead of three, then there Will be an overflow condition. In jumping on the stop emitter, Fig. 9c, from the last detail spot I65 to the l'20 spot it is found that the minor control contact DF28c is not closed and we have an overflow condition instead of a total condition. Since the next card advanced under the upper brushes is a "6 punched detail card, and since plugging from "6 is to line 12, etc., the stop emitter and record materials advance from line 19 of one form to line 12 of the next form.

If it is desired to stop bill printing to identify all overflow bills, then the "20 spot of the emitter Will also be plugged to the "S plug socket; The circuits for stopping the machine When the emitter brush touches spot "20 on an overfloW condition is as follows: line I83, Fig. 9c, Wire 24'3, pickup coil DF3'I, normally closed relay contacts DF33d (opened on a group change to prevent an overflow circuit), socket S, a Wire to spot 20, brushes I63, IM, contact ring 166 and Wire 229 to line I82. Relay DF3`I is held by a circuit including line I83, Wire 243, holding coil DFS'I, contacts DF3la, cam contacts CFI5 closed until the middle of the next cycle, Wire 229 and line I82. Near the bottom of Fig. 9c it is seen that relay DF3'I has normally closed contacts DF31b in the stop key circuit to relay R12 of the usual tabulator running controls. v

When the machine is again started, ;listin takes place for the remainder of the ten detail cards and then a group change is detected. Then both relays DF28 .and DF33' are energized. Relay DF28 closes contacts DF28c to make the "20 :asoaesa T19 spot of the emitter effective as the stopping position for total recording. At the same time relay DF3'3 is effective to `open contacts DF33b, Fig. 9d, to deenergize relay DFI!! which then opens contacts DFl9b, Fig. 9a, in series with the clutch magnet RM. Deenergization of magnet RM, Fig. 7, and restoration of lever 59 puts the hooked end 6| in the path of pawl 85 so that when the feed devices are restarted to go beyond line 20, the bill form passes the zero point and the register strip clutch is latched up with the register strip presenting a blank form with the dark stripe at the printing line where it remains until another arrears signal card is sensed.

It is at times desirable Ato stop the machine to identify or study special account groups such `as Government account cards. Such cards are double punched in one reserved columnand a detector circuit is provided to read and controlfrom such double punchings. In Fig. 9d the stopping control may be trace'd as follows: line 153, Wire 210, the common roller and through the first hole in the card by the lower brush LB, socket 245, vWire 246, socket 243, wire 248, normally closedrelay contacts DFI-35h, relay DF34, wire'29 and line [82. Relay DFM then calls in relay DFSE by the closure of contacts DF34b in series with relay DF35 and the cam contacts CBA closed for the firsthalf of the cycle and connected-to line 183 by Wire v250.

Relay DF35then shifts its contacts to open contacts DF35b and close contacts' DFizi` in series With the pickup coil of another relay DFfi which is energized by the second hole in the Government account card. A sustaining circuit for relay DF35 is established through line |83, wire 259, cam contacts CB2A, wire 25|, relay contacts D'Fa, holding coil DFSB and -wire 249 to line |82. Relay DF36 has normally closed contacts DFlLFig. 9a, in series with the many other stop controls of the regular tabulator circuit. Opening of contacts DF36b stops the machine for manual identification and treatment of the bill.

In addition to the automatic advance of the register strip under control of the X punching in an arrears signal card, there are two other manual means for ad'vancing the register strip. In two instances the clutch magnet RM must be energized first in order to connect the pin wheel shaft 88 of the register drive to the main drive. It is already explained that relay DFIS, Fig. 9a, closes contacts DFIQZ) in series with magnet Rlvi to effect automaticl clutch operation for dual feeding. Now it may be noted that switch SW'Z is inshunt with contacts DF 9b and can be closed at any time early in a bill. feed operation to cause cluteh connection for dual feeding. As a third control, a knob is fastened to the outer end of shaft 88 for manual advance of the register strip.

A sheet stop and signal device is provided under control of paper levers cooperating with both recordmaterials to detect exhaustion of one or the other or both. Relay DFIB, Fig. 9a,A is called 'into operation by the closure of lever contacts PLC. There are two levers Operating on the contacts, lever LI resting on the bill strip so that when it is exhausted, the lever rocks and closes contacts PLC. The otherlever L2 rests on the register strip so that when it is exhausted it also closes contacts PLC.

The pickup of the machine stop and strip exhaustion signal is withheld until a bill form is completed by interposing total and group control relay contacts DF28e between paper lever contacts PLC and relay .DF|.8. Asv 8. total is printed7 relay contacts DFZBe close,l and if paper in either strip is in a short length behind the platen, lever contacts PLC -are lalso 'closed and the pickup coil of 'relay' DFI8 is energ'ized.

Near the bottom 'of Fig. 9a it is seen that a holding circuit for relay DFJ8 and asignal lamp SL passes through contacts DFIBa, wire 200, cam contacts CF52 and 'Wire 225. In orderto stop the machine, the normally closed contacts .DF|86, Fig. 9c,zare opened in series with the usual stop key circuit for maintaining the tabulator in operation by means of relay R I 2.
