Claims.

This invention relates to paper feeding, and more particularly to the feed of paper past a printing position in business machines.

A large portion of the printing done on business machines is on forms, such as bills, ledger sheets, report forms, checks, etc. It has become the practice to print these forms on webs of paper which are fed through the machine. It is obvious that the length and layout of each particular form will vary slightly, and in many instances a great deal, especially as to length. For instance, bill forms may range anywhere from three and one half inches in length to twelve or fourteen inches; also, checks may vary from two and three quarter inches to three and one half inches. It is, therefore, obvious that a paper feed which is adaptable to feed a three and one half inch form would not be suitable for one, say, of seven and one half inches.

Also, it is desirable, under certain conditions, to print certain data, such as totals, on or near the bottom of any form whether it be short or long. Each variation as to length of form necessitates a change or adjustment of the feeding mechanism, often resulting in a complicated device which is not only expensive but difficult to maintain in working order.

Regardless of the length of a bill form, there are many instances where the number of items relating to one transaction is greater than the number of lines in the body of the form. It is, therefore, necessary to print the remainder of said items on the next form. Most bill forms have an address block in which it is not desirable to print items, therefore, it is necessary that the paper feed be constituted to skip over the address block and stop the paper on the first line of the body of the bill.

A further difiiculty often arises in feed mechanisms for web paper, 1. e., the paper becomes fouled with the inking ribbon upon being initially inserted in the machine.

It is, therefore, the principal object of this invention to provide a feeding mechanism which will feed forms of any length or layout to the printing line of a business machine.

A further object is to provide a feed which is simple and easy for the operator to adjust.

Another object is to provide a feeding device into which the paper may be easily introduced without fear of fouling the ribbon.

The principal feature of the invention resides in the provision of a control tape, perforated in accordance with the printed form to be used, which controls electrical means whereby the 2 paper is fed under the joint control of the machine and the tape.

A further feature is the provision of driving means, separate from that of the business machine, which is controlled by both the tap and machine functions.

Another feature is that the paper feed mechanism is pivotally mounted on the business machine in such manner that it may be swung clear of the machine to permit easy accessibility while starting a web of forms through the machine.

A more clear conception of the operation, construction and further objects of the invention may be had from the following specification when read in the light of the drawing, in which Fig. l is a cross section through a tabulator to show the invention thereon in a position to receive paper;

Fig. 2 is a side view of an embodiment of the invention;

Fig. 13 shows a form adapted to be printed by the machine and its associated control tape; and

Fig. 14 is a diagram of the electrical control circuit.

The preferred embodiment of the invention is shown on a record controlled tabulating machine, such as that disclosed and described in Patent 2,381,361 to John Mueller. It may be well at this point to call attention to the fact that feeds such as single, double, and triple spacing are under control of the tabulator as described in the above patent, but long feeds of the paper,

such as those over titles and in compensating, are controlled by the present invention. Certain conditions of long feed are controlled by functions of the machine, such as total taking, change of designation, and printing. These functions will be described hereinafter in the operation of the invention.

In View of the fact that the tabulator is fully disclosed and described. in the above mentioned patent, only those parts necessary for an understanding of the invention will he described, using the same reference characters in said patent. Referring to Fig. 1, cards are fed from magazine I20 located between the base frames Hill, by a picker knife H8 to the feed rolls I38 which convey the card to a sensing chamber I22 where the perforations therein are sensed by sensing pins I38 which pass through the card, raising lock pins I46. Located between the upper side frames IOI is a translator 238 carrying wires 2'43 Whichtransmit the motionof pins I 15 to the permutation slides 235 ofa decoding unit. The slides 235-are positioned in accordance with the coded data and set-5170195225 which, in turn, cooperate with a stepped heel 205 on a type rack I95. The type racks are cyclically released and rise under spring tension to position the type bars I97. I

Each row of lock pins-143 controls a s1ide420 which is actuated upon a change of data occurring in that column, and controls atotal taking mechanism described in the'above patent, which, in turn, controls a totalshaft 426 which shaft controls the taking of totals from the accumulators 20.

Paper feed' carriage The embodiment of the invention comprises.

driven by a separate motorunder control of a perforated tape. The carriage comprises two side frames IEl (Figs. 3, 4, and secured together by a cross member II and two tieiods I2. ifhe carriage is pivotally mounted with relation to the tabulator on a. U shaped bracket I i which is slidably mounted in a block I5 secured to the upper side frame IilLof the tabulator. Bars i3, fastened in any well known manner, hold the bracket I4 in the block. I5. The bracket I4 is provided with trunnions for a shaft I! journaled in the side frames If! of the carriage. The shaft I! acts as a pivot about which the. carriage may be rocked from the position of Fig. 2 to that of Fig. l, to permit easy threading of a new web of paper or a new ribbon into place. The block I5 is threaded to accommodate a threaded shaft I8 which co-acts with threaded bosses on the side frames I5. A handle 21 on shaft Iilpermits the carriage to be adjusted laterally withrespect to the type bars I91.

Mounted in each frame It is a knurled set screw 22, with a locking nut thereon (Fig. 3), which acts as a feed unit, supporting member when said unit is in operating position, and provides a means for adjusting the clearancerbetween the paper feed unit and the tabulator frame. A latch 23 secured to a cross shaft 2s mounted on the tabulator frame engages a cross rod 25, secured between frames I8, which looks and retains the paper feed unit in operative position. 7 A hand lever 25,. secured to shaft 24'is provided for rocking latch 23 to ineffective position. Also mounted on frame. II] is a latch 27 adapted to engage bar I6 (Fig. 1) to support said unit when said unit is in open or inoperative position. Latch 21, which is centrally pivoted, is urged into engagement with bar I6 by spring 23 and remains in that position until released. To accomplish unlatching, a slight pressure by the operator, extending spring 28, moves latch 21 away from bar I6, permitting the unit to be urged into its closed or operative position.

In order to lift the paper feed unit easily to its inoperative position and to prevent slamming when the unit is lowered, two springs 35 are provided. (Figs. 3 and l) wound on each end of the 'shaft IT. The springs 30 are compressed by pins 3| mounted on the frames I9 and the brackets iii so that the springs'have a tendency to lift the paper feed unit away from the brackets is and the machine frame.

Two pairs of feed rolls 32 and 33 are provided, each of which has pins 3 3 in the periphery thereof adaptedto engage perforations. in the margin of the web of paper 29..to be fed. As. seenin Fig. 10 the paper 29 ispassed around. the upper periphery of the feedrolls 32,- around the. roll 35,

past the printing platen 35,. around free. roll.

3? and then back over the upper. periphery of the feed rolls33. The feedrolls 32 and 33 are drum shapedand are adiustablelaterally of the carriage to accommodate any width of paper, as will be describedlater. Each rollv 32 or. 33 is fastened to its respective drive shaft by a set screw in the hub thereof. Each of the feed rolls is provided with a pressureroll: 38 .which. is grooved to straddle pins 34, and is adapted to maintain the paper in contact with the said pins. The pressure rolls 38 are carried on arms it (Fig. 5) pivotally mounted in a bracket l-I supported onthe drive shafts I7 and 42. A tension spring 43 wrapped around a central pivot d lfor arms 43 acts on pins 45 in each arm to tension the pressure rolls 35 against their respective feed rolls. Rolls 35. and 37 .are also provided with pressure rolls 39. Each roll 32 or 33 is rigidly secured to its respective drive shaft 42 or I! by a set screw, and a loosening of. the set screws.

will permit sliding of the wheels to the desired distance from the central guidediscs lfi.

While the brackets 4L are free on the shafts, the grooves in the pressure rolls 38,. engaging the pins 34 in the rolls 32or 33, tend to maintain the pressure rolls in correct alignment with their respective feed rolls.

Feed rolls 32 and 33 are driven from two sources, one the line spacing mechanism of the tabulator and the other an independent motor. Secured to drive shaft I'l, or feed roll 33 is a miter gear 50, which meshes with a miter gear 5I secured to one end of a stub shaft 52 journaled in the right hand carriage frame It. Secured to the other end of shaft 52 is a miter gear 53, which meshes .With a miter gear 54 secured to drive shaft. for feed roll 32. The ratio of said gears is such that both feed rolls rotate at the same peripheral speed. Journaled in bearings on the side frame Ill-is a shaft 55, to one end of which is secured a miter gear 56 meshing with miter gear 54. On the other end of shaft 55 is secured a miter gear 51 meshing with miter gear 58 secured to a shaft on which roller 35 is free to rotate, The shaft 59 is similar to a standard typewriter platen shaft, in that it is provided with the usualpositioning knobs ill and linespacing mechanism.

The line space actuating mechanism (as shown in Fig. 8-) comprises a cam 13 2-, mounted on shaft I84, which cooperates with a follower roller 'I3I mounted on bell-crank I30 pivoted on a stud I02. Pivoted to the other end of bell-crank I30 is a link 128 which is, in turn, pivotally secured to arm I26 fast on shaft 121 journaled in the side frame IOI. Also secured to shaft I21 is arm 6I having a pin therein that is engageable with electrical contacts for controlling the operating circuit. A description of the electrical circuit containing said contacts will be given hereinafter. Arm I26 also carries a roller I25 that co-acts with bail 63 carried on arms 64 journaled on shaft 65. Pivoted to arm 64 is one end of link 66, the other end of which is pivotally secured to one corner of a triangular plate 61. To another corner of plate 61 is pivoted link 68. Secured to the third corner of plate 6'! is one end of a strong spring 69, the other end of which is secured to a stud in frame I0. Said spring urges plate 61 counter-clockwise. Link 68 is secured to drive a pawl I cooperating with a ratchet II secured to shaft 60. The high portion of cam I32 will rock bell-crank I30 counterclockwise, raising roller I25 through link I28 to rock bail arms 64 which, in turn, will rock plate 61 clockwise through link 66, thus pushing link 68 to the left (Fig. 8) and rotating ratchet II clockwise. This rotation is transmitted to feed roll drive shaft 60 which, in turn, drives feed rolls 32 and 33 through the gear train 58, 51 (Figs. 2 and 4), shaft 55, gears 56, 54, 53, shaft 52, and gears 5I and 50. It will be noted that the arrangement of the above gear train is such that clockwise rotation of shaft 50 by ratchet II results in clockwise rotation of feed roll 32 and counter-clockwise rotation of feed roll 33.

Print platen actuating mechanism The printing platen actuating mechanism is operated substantially in the same manner as that described in Patent 2,381,361, and will be but briefly described herein, using reference characters, for old parts, identical with those in the patent. On the left hand side of the tabulator (as shown in Fig. 8), a lever I83 pivotally mounted on a shaft I04 has a forwardly extending arm to which is connected a pull link I09, the lower end of said link being connected to lever I06 which is pivotally mounted on a stud I02, and having thereon a follower roller I01. Said roller engages with a cam 108 secured on a shaft I 85. Means are provided that co-act with the lever 103 to prevent platen movement on non printing cycles, and are identical to those shown in the cited patent and, therefore, will not be recited herein. Lever 103, through roller I05, presses against bail I3 supported by arms I4 fast on shaft 65. Also secured to shaft 65 are arms I6 that are pivoted to ribbon and print platen supporting arms I5 (see Fig. 9)

Said arms are slidably supported on side frame pieces ID by pin and slot connections 18, I9. The arms I5 have a bent-over portion (Fig. 9) which tends to hold the paper away from the platen so that when the arms I5 are reciprocated, bringing the platen into printing position as will be presently described, the slack in the paper will be taken up and thus prevent tearing of the paper. Journaled in arms I5 is a printing platen 36. This mechanism, when operated, moves platen 36 and the paper thereon into printing position, in the following manner: Roller 101 riding on the high dwell of cam 108 rocks lever I06 counter-clockwise, pulling link 109 down-' wardly which, in turn, rocks lever I03 counterclockwise, thereby raising bail T3, and through arms 14 and 16 moves arms 15 and platen 36 rearwardly. Springs 11, which are fastened at one end to arms 15 and at the other to pins 18 secured in side frame I0, are provided to move the printing platen 36 toward the type I91 to effect printing. Follower roller I01, upon entering the low dwell of cam 108, allows springs TI to move arms I5 and platen 36 forward. The arms 15 press against ribbon 80, stretching same to overcome the normal sagging tendency. Previous to this invention, it was found that the type sector bars ascending and descending had a tendency to catch and tear or otherwise damage the ribbon. This feature of the invention, the forward movement of the platen 36 with arms I5 extending the ribbon toward the type I91 onlywhen the type sector bars I95 are positioned for printing and the return of said arms and ribbon immediately after printing, eliminates the undesirable mutilation of the ribbon.

Ribbon feed mechanism A bracket 8|, mounted on the outer side of each of the upper side frames III! of the tabulator and immediately below the paper feed unit, has a mounting stud 82 for a ribbon spool 83 or 84 secured therein. The brackets BI also support their related drive mechanisms, as shown in Figs. 2, 5, and 6. A link 85 pivotally secured to a rotating disc 86 fast on the tabulator front head drive shaft I85 is connected to a stud 81 mounted on arm 88 free on a. shaft 90. Also pivoted on stud 87 is a latching link 9| having a pin 92 thereon that co-acts with detent notches in a latching member 93 that is pivoted on a stud 95 mounted on the bracket 8 I. Secured to latching plate 93 is an arm 94 having a protrusion 96 formed at its extremity which is adapted to be engaged by a spring pressed latch 91 pivoted on the bracket 8|. The latch 91 is provided with a ribbon engaging pin 98. Also attached to arm 94 is a link I02 connected to an arm I03 fast on shaft 90. Mounted on a stud I05 in the other bracket 8| is an arm I04. Attached to arm I84 is a link I06 which, in turn, is attached to an arm I01 fast on shaft 90. A blocking member II 0 is pivoted on a stud III mounted in the bracket BI and has secured thereon a ribbon engaging pin II2.

A driving mechanism for rotating each of the ribbon spools 83 or 84 is provided which comprises a ratchet wheel H3 and a pawl H4. The pawl I I4 is carried on an arm I I5 pivoted on the spool spindle 82 on which the ratchet wheel H3 is pivotally mounted. The ratchet wheel I I3 is held on the spindle 82 by a spring and washer as shown in Figs. 6 and 7 which are drawn against the wheel I I 3 by a nut shown in Fig. 7. The arm I I5 is provided with a roller II6 which is held in contact with either arm 94 or I04 by spring H1. Arms 94 or I64 are rocked once each machine cycle by shaft which is, in turn, rocked by link 85 acting through arm 88, link 9|, detent plate 93, arm 94, and link I02, to arm I03, fast on the shaft.

In the position shown in Fig. 6, the ribbon which is fed around the roller 12 and through the guides I2I has nearly filled the left hand spool 83, permitting latch 91 to engage and lock arm 94 from rocking. On the next reciprocation of link 85, the arm 94 and detent plate 93 will be held, and the link 9I will move the pin 92 therein from one detent notch to the other, the

roller H 6 i being at this-time in dontactwith the stationarily held arm 96 asillustrated in Fig 6, and the arm I 15 and the pawl H 4 occupyingtheir normalor idle positions wherein thepawl is rocked out of engagement with the ratchet wheel I13 by the engagement of a-tail lon'said paw-1: with the stop pin projecting from the hracket BI as also illustrated inFig. 6.- On the return or counter-clockwise reciprocation of link 85, the arm 94 will be rocked countereclockwiseaway from roller H5 and arm I04 will actuate the ratchet arm H5 of the drive of the right handspool 3 2. From this time on, arm- I04 will be effective until-the right hand spool is filled; Uri-- der this condition, the nose of blocking arm- H0, which carries the-ribbon sensing pin H2, will be rocked into the path of the arm '04. This Will preventthe arm I04 frombeing rocked the full feeding distance andthe pin 92 in arm 94 will snap into the first notch of'plate '93, thus making arm 94 efiective and arm I04 ineffective.

High speed paper drive actuating mechanism Secured to the right hand frame I is a bracket #23 (Figs B, 4, and on which is mounteda second bracket i24. Pivotally'rnounted in frame 50 and bracket I24 is a motor I25 which has secured to its armature shaft I26 a worm I21 adapted to co-act with the worm wheel I28 secured to shaft 42. A toothed wheel I30 is also secured to shaft 42 and is engageable with a toothed braking arm I31, pivotally mounted on a bracket I32, whichis secured to motor I25. Braking arm I3i is formedv of a plurality of toothed plates the first ofwhich has a turned over lug I33. engaging .bracket I32 and is held against said bracket by a spring I34. The engagementor disengagement o1 worm I21, worm wheel I28 and braking arm I3I with wheel I30 is controlled by means of an arm I35 mounted on motor I25 and extending forwardly therefrom.

The rocking of motor 425 is controlled by two solenoids I33 and I31. The plunger 833 of the solenoid I35 passes through a slot in arm 35 and is adjusted in relation thereto by lock nuts I45. A latch M0, pivoted on a stud I42 in the frame I3, is adapted to cooperate with the arm I35 of motor l25. The latch M0 is formed with a horizontal arm having a slot therein for accommodatingthe plunger I43 of solenoid 831,

said plunger being provided withan adjusting lock nut I44. A contact breaker arm Hi5 (shown in Figs. 3 and 12) is slidably mounted on an upright arm I41 secured to the bracket I23. It is urged downwardly by light spring M9 connected between a pin on the bracket and a pin on the arm. The bottom of breaker arm I45 is provided with a contact cooperating with a spring contact, I50 also mounted on, but insulated from, bracket I23. When solenoid I35 is energized, as will be explained hereinafter, the arm I35 is drawn down by plunger I38 into locking engagement with latch 540. The rocking of arm I35 rocks motor 25, disengaging worm I21 from worm wheel I28 and engaging braking arm I3I with serrated wheel I30.

with

positive engagement with wheel 30, and also permits a certain amount of overthrow inrocking' the motor. The arm I-35snaps past latch Hi0 and lowers arm I45, breaking contact I53 (Fig. 1 l )-,-Which immediately opensthecircuit to the solenoid I36, thus permitting plunger I30to rise underthe tension of -spring I51 until arm I35 is caught by the latch I40. In thisposition the motorhas rocked clockwise through a sufiicient arc-to disengage braking arm 53! from toothed. wheel I30, but not sufiicient to engage worm I21 and worm wheel I28. placed under control of the linespacing mecha.-. nism.

' When the control tape calls fora long feed, the solenoid I-31 isenergized, rocking latch I40. clock wise; thus releasing arm I35 and permitting the motor I25 to rock counter-clockwise (Fig. 3) under the influence of spring 15! and the weight of the-worm. This rocking brings worm I21 and worm wheel I28 into mesh, thus-starting the long feed through rolls 32 and 33.

7, Control tape As has been noted above, the paper web is fed either by thelinespacing mechanism of the tabulator, or by the-long feed device under control is to occur in relationto'the form being feel. in

Fig. 13 is shown a bill form I55 on which it is desired to print a nameand address in the blank space at the top of the form, and then print items, the total of which is to be printedbelow saiditems. After printing the total it is desired that. thepaper be fed to the first linev of the address .block and stopped, regardless of the line on which the total wasprinted. If, however, a total was not taken within the body of one bill form, it is desired that the paper be fed over the address block and stopped on the first line of the body of the next bill.

There are four lines of control perforations in. the tape for performing these operations, one (I60) for starting the long feed, i. e., engaging worm l21 and worm wheel I28, two (ifiI) for stopping the feed if a total has not been taken within the body of the bill, i. e., disengaging worxn I21 and worm wheel I28, three (132) for C011". trolling the stopping circuits, and four (I531) for stopping the feed if a total has been taken within thebody of the bill.

In view of the fact that the printing on a particular web of forms is repeated over and over, the tape I55 is formed in a loop which is fed in synchronism with the web.

Tape feed mechanism A drum I51 of similar diameter to drums 32. and 33 is secured to the end of drive shaft 32 and has pins I58 in the periphery thereof for en agement with the drive perforations in the control tape. The drum is of suitable conductive material and is insulated from the shaft 42. A brush I64 bearing on the face thereof carries the electric circuit through the drum. A second drum I65 is journaled on an arm I36 and located beneath drum I51. The arm I66 is pivotally mounted on frame I0. said arm being urged scen The paper feed is thuster-clockwise gravitationally to provide tension between said drums when tape I55 is supported thereon.

An arm I6! is pivoted on a stud I 68 in bracket I24 and supports five insulated contact brushes I64, I10, I1I, I12, and. I13, which are urged counter-clockwise against drum I51 by the camming action of a lip I14 formed on arm I61 and a follower roller on an arm I journaled to bracket I24 and urged counter-clockwise by spring I16. Said lip and arm also comprise a latching means whereby brush supporting arm I61 may be held away from drum I66 and retained in that position so as to facilitate the positioning of tape I55 on the drums I51 and I65.

The operator, in setting the carriage at the beginning of a printing operation, rocks handle 26 counter-clockwise (Fig. 3), thus unlatching the carriage and permitting it to swing about shaft I1 to the position of Fig. 1. In this position the web may be fed around the rolls as indicated in Fig. 10. The latch 21, which has been holding the carriage in position, is then tripped and the carriage closed against the action of spring 30 until the latch 23 engages the rod 25. By using the knobs 41 the paper may be positioned to the correct alignment for the start of printing. The paper can then be aligned laterally by use of the crank 2I which will shift the entire carriage with respect to the type I91.

The tape I 55 is then positioned on the drum I '51 with an indicator line I11 in alignment with an indicator I18. The line I11 is a reference line from which all control perforations are made, thus said perforations must be in alignment with the positions in which certain operations are to occur with respect to the particular form being used.

Electrical control circuits Several electrical circuits in conjunction with mechanical means are employed to control the various paper feeding operations, the general aim being the regulation of the long or rapid paper feeding mechanism and, more specifically, the engaging and disengaging of motor I25 with its associated mechanism. The primary electrical circuit, with reference to Fig. 14, herein employed, shows an alternating current source and a rectified secondary source being used to furnish the potential necessary for operating the various solenoids and relays. Although this method is presently employed, other means may be substituted with the same results.

In view of the fact that certain machine operations, such as printing, change of designation, total taking, and the like, are used for controlling certain functions of the electric circuit, a plu rality of contacts I80, I8I, I82, I83, and I84 are provided. Each of the above contacts is provided with a bridging switch, by means of which said contacts may be cut in and out of circuit in accordance with the requirements of the form being fed.

In the example to be described, i. e., the form I56 of Fig. 13, contact I80, which is associated with the print mechanism (see Fig. 8), and contact I8I, which is actuated by the total shaft 426, are used, therefore, their associated bridging switches are shown open and the remainder closed.

In operation, when the brush I13 enters the first control hole I63, a circuit is closed from positive conductor I86, conductor I81, brush I64, drum I51, through control hole I63, brush I13, over conductor I88, the outer break Contact of relay A, conductor I89, through the winding of Stop solenoid I36, through contact I50, to negative conductor I90, thus operating the Stop solenoid I36 to rock motor I25, thus disengaging the worm drive. A parallel circuit is closed from positive conductor I86, conductor I81, brush I64, drum I51, through control hol I63, brush I13, over conductor I88, through the outer break contacts of relay A, conductor I9I, winding of relay 0, conductor I92 to negative conductor I90, operating relay C, which opens any lockin circuits previously established for relays A and B. The position of hole I63 With relation to the form I56 is such that the long feed stops on the first line of the address block. The machine line space mechanism now takes over the feeding of the paper which is fed for the three lines of the address, and on the third line, a control hole in the last card of the address group causes a double line spacing of the pap-tr over the form line to the next printing line, which is the first item line. This brings control perforation I6I in the tape under brush I1I, but due to the fact that relay A has not been operated at this time no circuit will be closed to the Stop magnet I36.

The tabulator continues to print and line space and upon reaching hole I62 in the control tape, a circuit will close from positive conductor I86, conductor I 81, brush I64, drum I51, through hole I62, to brush I12, conductor I93, through winding of relay A, over conductors I94, I92 to negative conductor I90, thus operating relay A. Relay A is then looked up over a circuit from negative conductor I90, conductors I 92 and I94, through the Winding and inner make contacts thereof, inner break contact of relay B, and break contact of relay C, over conductors I 96 and I98 to positive conductor I 86,- thus holding relay A operated under control of relays B and C, and transferring the circuit for theStop-solenoid I38 from brush I13 tobrush I1I.

This circuit having been established, th machine continues to print items until such time as the total shaft 426 is rocked to take a total, closing contacts I8I. This has no effect other than to prepare a circuit, as no operation of the long feed is desired until the printing of the total is completed. The operation of printing closes contact I which then completes a circuit from positive conductor 586, contacts I80 and I8I, through cut out switches for contacts I 82, I83 and I84, conductor 200, through winding of relay B, over conductors 2M and I92 to negative conductor I90, thus operating relay B, and opening the locking circuit for relay A, which releases again, placing the Stop solenoid I36 under control of brush I 13. The operation of relay B also closes, through its outer make contact, a circuit from positive conductor I86, conductors I98, outer make contact of relay B, conductors 202 and 203, through the winding of the Go solenoid I31, over conductor I92, to negative conductor I90, thus rocking latch I40 to permit the rocking motor I25 to engage worm I21 and worm wheel I28 to feed the paper to a point opposite hole I63 in the control tape. Hole I 63 closes a circuit from positive conductor I86, conductor I81, brush I64, drum I51, through hole I 63, brush I13, conductor I 88, outer break contact of relay A (which, as will be recalled, was released by the operation of relay B), conductor I89, through the winding of the Stop solenoid I36, through contacts I50 to negative conductor I90, thus disengaging the worm drive at the first line of the next heading group, thereby allowing the machine to take over 1'1 7 single :line spacing :until ihole 16! passes under brush .2 l. However, since-ihole MI is one of the controls forthe Stop :soleno'id I38, it is, at this time, ine'fective as relayvAiis normal, a total having been taken in the previous form. Items are printed and the tape progresses to control hole 1 62. A circuit is then established, the same as that previously described, resultin in relay A being operated and itsassociated locking circuit closed, holding it operated. The printing of items is continued until control hole I60, which is opposite the last line of the form, makes contact with brush 1 which closes :a circuit from positive conductor 'l'sfi'conductor I81, brush i5 3, drum 157, through hole I60 :to brush H3, over conductor 293, through the winding of the Go solenoid l3! to negative conductor I90, thus energiizing the Go solenoid and engaging the worm drive I213! 28 whichfeeds-the paper to the first "item line of the .next group, i. e., control hole use. Since relay A is energized, control hole [53, passing underbrush 113, was ineffective as the circuit therefrom passes through a break or open contact. Control hole -1B establishes acircuit from positive conductor ltd-conductor 11H, brush I64, :dr-um 15?, through hole 6'! brush l-il conductor .2014, outer make :contacts of relay A, over conductor i389, throu'g-h the winding of the Stop solenoid 136 through contacts I50 to negative conducitor 19E], thus energizingthe Stop solenoid and disengaging the worm drive I 21, 1 28,stopping the web at Itheafirst titem line after skipping the address block and permitting the tabulator to resume normal line spacing operation. The item printing carries control hole I152 under'brush I12, but since relay A is in a lockedposition, control hol 452 is ineffective in this present instance.

'It is obvious from the above example that any type of formmayibe fed through the tabulator, providing the correct combination of control holes are entered in the tape U55 and in the correct relation with the form to be fed. For instance, if a web of checksis to .be fed, on each of which checks onlyone line of printing is desired, i. e., the payees name and the amount. only one control'hole :is required. This control hole I63 controls the Stop solenoid 4'36. If .all the cut out switches, except that associated with print contact I80, are closed, the operation would be as follows: "The tabulator prints the payees name and amount on the check, closing the contact l8!) which actuates relay 3, closing the ciredit for operating the ?Go solenoid I31 which engages the worm drive I21, 128 and feeds the web until the control hole 163, which is opposite the printing line, closes :the :circuit for the Stop solenoid 13B, disengaging the worm drive 421, 12-8, thus holding the paper for the :next printing operation.
