PAPER FEEDING DEVICE loyno Ghertlmann, I Saint Maude, France, assignor to International Business Machines Corporation, New York, N. Y., a corporation of New York Application September 24, 1936, Serial No. 102,279 In France November 6, 1935 13 Claims. lci. 235-121.?)

This invention relates generally to paper feeding control devices and more specifically to devices for controlling the printing of various forms of records in a perforated card controlled tabulator.

an object of the invention is to provide feeding devices for handling forms of statements, receipts, invoices, etc., so that printing is started at the proper position on each of a succession of such forms and if the number of items is greater than the number of lines on a form, printing will continue automatically at the proper position on the following form.

Another object of the invention is to adapt the feeding devices for control by a card controlled tabulator wherein the cards are arranged in roups. with means for feeding the record -sheet automatically from. form to form whenever card groups change. The extent of feed is automatically controlled to put a form in place with its first line in printing position regardless of the number of lines printed on the previous form when a group change occurs.

An object of the invention is to provide means for stopp ng the record paper for the printing of a first line at any desired location on a form, the feeding movement of the paper up to the first line of the following form being resumed either immediately after the printing of a single line on the form or after the printing of several consecutive lines and a total which may or may not be carried forward to the first line of the following form.

An object of the invention is to provide record sheet form feeding devices which are controlled by sets of perforations in the forms, there being one or two marginal perforations in one or both margins of each form to control the starting and stopping of the sheet feeding devices. The perforations permit electric contact between adjustable brushes and a plate over which the live forms move, causing operation of a magnetic clutch to disengage the drive to the platen roller. Subsequent connection of the drive to the platen each group relating to a separate form,

on each form together with the printing of a total after the last printed line in the list: the machine functioning with automatic group control and a single perforation being provided on the side of each form, the printing of the various items will occur each beneath the other, the functioning of the automatic control will cause the printing of the total below the last line of the list and then the paper is fed forward and the perforation on the following form will stop the paper with the first line of print of the following form in printing position.

3. The printing of the items of any one group of cards on several forms with apro ressive total printed at the top of each one of them: the machine functioning with the automatic group control and the device mtaking progressive totals, two perforations being provided on each form, one on the left and one on the right, the right hand perforation of a form causing printing of a Progressive total on the preceding form below the last item listed on said form, then feeding is stopped by the left hand perforation of the following form with the first line of print of the form in its printing position, the progressive total printed on the preceding form being repeated on said first line of the following form while the selection of a clearing operation will finally cause the printing of the general total after the last line of the list on the last form, following which the feeding of the paper will restart and willbe stopped by the left hand perforation of the next form in position to record the first items of a new group.

4. The printing of the total at the bottom of the form irrespective of the number of lines listed on said form: the machine functioning with the automatic group control and two perforations beis obtained by energization of another magnet I controlling the clutch whenever a line is printed, a total is printed, an automatic group change occurs, or a progressive total i printed.

By means of the devices f ggling the subject matter of the invention it is p ble to carry out the following form feeding operations:

1. The printing of a single line per form; the tabulating machine operating in listing and a single perforation being provided on the side of each form. feeding will occur after each line of print and the feed control indiclum or perforation of each form will stop the following form with its first line in printing position.

2. The printing of a variable number of lines ing provided on the side of each form, the functioning of the automatic control will cause the feeding of the paper which wili be stopped by the first perforation of the following form for the printing of the total at the bottom of the first form considered and said impression of the total causing a further feeding of the paper which is stopped by the second perforation of the following form with theflrst line of said last form in printing position.

5. Hie printing of the items of a group of cards on several forms with or without a total on each and without carrying forward a progressive total from one form to another: two perforations being provided on each form, one on the left and the other onthe right, the perforation on the right hand side of the following form will initiate the printing of the total of the items listed on the form considered even if, at this moment, the

functioning of the automatic group control does not occur, the feeding of the paper restarting automatically after the printing of said total until.

it is stopped by the left hand perforation on the form which comes after the following form which has just been referred to, with the first printing line of said following form in printing position.

The foregoing and other objects of the invention will become apparent as this specification continues with reference to the drawings forming part of the disclosure.

Fig. 13 is a timing chart of the contacts in the machine.

The feeding devices are incorporated in a card controlled machine of the kind disclosed in United States Patent No. 1,978,617. In such machines, record cards C (Fig. 11) are sensed to control accumulating and printing operations. These cards are arranged in groups according to group numbers perforated therein so that a series of related items may be added to form a total amount of the group. The cards are passed through the machine in succession and automatic group controldevices compare the group numbers on consecutive cards so that a group change may be detected. When such a change is detected, a total printing operation is initiated and the accumulator is reset.

The tabulator printing mechanism is shown in Fig. l2. There it is seen that a listing shaft I65 drives the mechanism during listing operations and a totaling reset shaft J66 drives it during total taking operations. The machine is provided with a number of can operated contacts identified by the prefix letters L and P, the former operated by cams on shafts that operate only during listing, and the latter operated by cams that rotate only during total taking as in Patent 1,976,611. The record strip R is held around a platen 2 and there receives the printing impressions. A printer control magnet PM is energized at a differential instant accordin to the time of sensing a perforation in the record card or the time that an accumulator controlled total contact is closed. -Moving in synchronism with the other tabulating mechanism is a type bar 2 I2 formed with notches 2I6 that are moved in succession past a stop pawl 2 l1. when magnet PM is energized it attracts an armature lever 22l to which is attached a call wire 220 connected at the opposite end to a latch 2 Ha. for releasing p wl 2". Thus the type bar 2l2 is stopped special cam Fig. 12.

differentially by the pawl engaging in one of the notches 216; the bar stopping between a hammer 224 and platen 2 to place at the printing line. type 2l8 corresponding to the value of the perforation or total amount sensed. For a more detailed understanding of the structure and operation of the tabulator, reference may be made to the patent identified hereinbefore.

The line spacing mechanism is shown in Fig. 11A where a shaft 208 is shown as having a space operating arm 262 secured to one end thereof. Shaft 20B is rocked on every printing cycle of the machine by the cams on shafts I65, I55,

Arm 262 (Fig. 11A) is rocked therewith and carries a pin 263 which is adapted to engage a member 26! integral with an arm 2B5 rotatable about a fixed pivot 286. The arm 265 is connected by a link 251 to an arm 268 which has a pin and slot connection 269 with an arm 212 pivoted on the supporting axis of the platen.

Arm 210 carries the spring pressed pawl 21! which is adapted to engage a ratchet 212, Fig. *6, for driving the platen 2. Clockwise rocking of shaft 228, Fig. 11A. accompanied by the upward movement of the printing cross-head will rock member 264 and arm 26! in a counterclockwise direction to cause actuation of the ratchet 212 in a clockwise direction and effect paper spacing before the printing hammers are tripped.

Arm 285 has secured thereto a further member 212 connected by a link 214 to an arm 215 loosely pivoted on the shaft 202, A pin 215, projecting from a mutilated gear 211 secured upon the total shaft ISO, is adapted to rock arm 215 during total taking operations to eflect an additional spacing operation of the platen. Pin 216 is so located that it actuates the paper spacing mechanism after the printing operation.

As shown in Fig. 6, the record forms are on a strip R which is unfolded out of a magazine I. passed around the platen roller 2 and then returned to a receiving magazine 2. The forms may be separated by printed dotted line across the strip, but perforated lines should be avoided because electrical contact is liable to be established therethrough.

In Figs. '1, 8, and 9 are shown the mechanisms by which platen 2 is turned to feed the strip. The platen may be turned under control of the listing shaft I85 or the reset shaft iii, the former turning one revolution on each listing cycle and the latter revolving on each total printing cycle. The shafts are connected to the platen shaft 2 through a chain 6 and three gears I, I and 9. The mechanism is mounted between a pair of side plates S and S fixed to the base B.

Fixed to the shaft IE6 is a ratchet wheel i0 engaging a pawl ll pivoted on a gear I! loosely mounted on the shaft. A spring l2 tends to keep the pawl in engagement. Gear l2 meshes with a gear ll loose on shaft I85 but carrying a pawl l5 which engages the teeth of a ratchet wheel I'l keyed on said list shaft I65. A spring l6 holds the pawl l8 against wheel ll. Gear II is formed with a sleeve 4 carrying a sprocket wheel it around which passes the chain I which also meshes with a sprocket wheel is loosely mounted on a shaft 5 which is keyed to the feeding drive gear I. The sprocket l9 may be connected to the drive gear I, gears 8 and 9, and platen 2, through a friction clutch comprising a friction disk 20 which is fastened on the sprocket and a slidable keyed sleeve 20 which may be pressed against disk 22 by spring l9 or moved away therefrom by electric controls about to be described.

It isapparent from the foregoing that when? clutch 20-20 is engaged. paper feed roller I is driven either by list shaft I65 or by reset shaft I66 according to which of said shafts is in rotation. If, for instance, it is the resetting shaft which is in operation, the drive of the roller-will occur through ratchet wheel I driving pawl II and consequently gear it in its rotation, said gear l3 driving gear ll the pawl of which will slide idly over ratchet wheel I! which is stationary (see arrows in Fig. 1 showing rotational direction of gears II and It) and through sprocket wheel ll solid with gear I and driving chain 0, sprocket 'wheel II and the series of gears I, I, and S. If on the contrary it is listing shaft I" which is in operation, it is ratchet wheel I! which, through pawl II, will drive gear ll, the rest of the movement continuing up to roller 2 in the same manner as in the other case: the rotation of gear It will actuate gear II, the eii'ect of which will simply be to cause pawl II to slide over the teeth of the stationary ratchet wheel II.

In other words. paper feed roller 2 rotates either through shaft I" or through shaft I" each time clutch 2l-2l is in engagement. An engaging electromagnet 2| makes it possible, by means of an associated armature 22 pivoting at to control eng ing sleeve II by a lever 22' arranged to bring it against disk II to determine clutch engagement. Magnet 2i trips the latch connections (Fig. 6A) which normally hold lever 28' and sleeve 20' (Fig. 9) out of clutching relationshln, against the tension of spring It. Lever 22' has an end which fits into the groove on sleeve 20'. and pivots on a vertical stud 2| (Fig. 'I) so that a block 28 thereon is in the path of a depending iinger its on armature 21. When the armature is attracted, finger as moves to the right (Fig. 6A) out of the path of block II and thereby releases lever 22 (Fig. 9) so that it may be rocked in a counterclockwise direction (clockwise in Fig. 6A) by spring ll to press sleeve 20' against disk 20 in driving relationship. A disengaging electromagnet 2| (Figs. 7 and 8) operates in an opposite way through an armature lever 2| cooperating with'lever 22' to shift sleeve II away from disk II, compress spring II and relatch lever 21 and block II behind armature finger its and thus stop the rotation of platen 2 and the feed of the paper strip. Lever 24' pivots on a rod 24b and carries an adjustable projection 28a pushing against the end of lever I! so that it may be rocked in a clockwise direction (Fig. 9) and relatched as shown in Fig. 6A.

The devices for controlling the energization of magnets II and 2| which make it possible to engage or disengage the clutch for controlling the platen drive will now be explained.

Energization of engaging magnet 2| is obtained either under control of the print devices when listing, operation of the automatic group control devices, the means for printing a progressive total, the actuation of the major, intermediate or minor total control, the operation of class selection devices by special cards, or finally through the action of a marginal perforation provided on one side of a record form in cooperation with an adjustable brush 26 (Fig. 6) adapted to contact a conducting plate 2! when a start indicium or perforation appears under the brush, said plate 21 serving at the same time as a guide for the paper.

Paper ieeding is stopped in order that a single line may be printed, or the first line as an item or a progressive total may be printed, or totals may be impressed in the desired position on a form, any of the aforesaid controls being produced by devices including an adjustable brush 2! cooperating with the left side of strip R and contacting with plate 21 at times determined by the differential placement of marginal stop indicia or perforations in the forms.

A third adjustable brush 28 is out of line with the perforations in the strip because it is provided merely to sense the passage of the end of the record strip It. When the end passes the brush 2!, contact withplate 21 is established and a means is activated to stop the tabulator so that no more cards are fed.

The electrical connections about to be considered make it possible to control the energizatlcn of engaging magnet 2| and disengaging magnet 24 and consequently the engagin or disengaging of the paper feed device. These connections not only include the sensing devices cooperating with the strip, but also modifications in the wiring of the tabulating machine in order to obtain the control of printing in any desired position on a form.

Reference may be made to Fig. 10 where is shown the electrical strip sensing'controls that are connected to printing tabul ator so that it may fulfill the various requirements indicated hereinbefore. As seen in this diagram, brush II, which controls to stop the feeding of cards when the paper strip comes to an end, is connected by a wire 29 to a stop relay 10 which acts, when energized, to open contacts lib (Fig. 10A) in series with the stop key contacts I. of the tabulator. On wire is is also located a hand-controlled switch 31 which is closed when'it is desired to bring into action the sensing devices forming part of the subject matter of the in vention. Plate 21, with which brush it makes contact when there is no more paper available for passing over printing roller 1, is connected to wires ll, 84 and 62 leading to an opposite main line ill and in the path of which is positioned a hand-operated switch 35 which is closed when it is desired to utilize the paper feed devices which form the subject matter of the present invention.

It should be noted that main lines I, "I are connected to the tabulator wiring in Fig. 10A and are energized when a switch P8 is closed to connect to the power source. It should likewise be noted that the electric connection shown at 21' in Fig. 10 is merely a diagrammatic indication, said connection being obtained in actual practice by conducting plate 21 itself. From the foregoing it will be seen that when the paper passes over plate 21 to pass round printing roller 2, it insulates brush it from platejl; consequently relay 30 is not energized and its contact 30b (Fig. 10A) does not break the energizing circuit of the engaging electromagnet of the card feed device and said cards continue to pass through the machine unless other operations (automatic control, stop key operation, etc.) stop said feed in the usual manner. 0n the contrary, if ,there is no more paper passing under brush II, that is to say, if there is no other form ready to pass over roller 2 for printing, brush 28 makes contact with plate 21 and the following circuit is set up in consequence: line I", switch ll.

avoid sparking on the breaking relay 3|), wire 29, brush 2!, plate 21-21, wire 33, switch 35, wires 54 and 62, and line 33L Consequently, relay 30 is energized which causes, as hereinabove indicated, the breaking of the energizing circuit of the engaging electromagnet of the tabulator card feeding devices.

When it is energized, electromagnet 30 also controls the breaking of contact 30a which is normally closed. the effect of which, when there is no more paper passing on plate 21, is to suppress all action of the paper feeding devices.

One circuit which is influenced by the opening of contact 30a is the circuit containing left hand brush 25 and the disengaging magnet 24 for stopping the paper feed mechanism. This brush 25 is provided to sense the appearance of a left hand marginal perforation in the paper and thereby energize magnet 24 by means of a circuit including line 33!, wires 82 and 64, switch 35, wire 33, connection 21', plate 21, brush 25, wire 31, magnet 24, wire 38, contact 300, wire 2!, switch II and line 330. A progressive total control circuit is also influenced by operation of contact 20a, because it follows a path through line 330, switch 3|, wire 29, contact Illa, wire 28a, bus bar 39, wire 4|, progressive total relay 42, progressive total magnet 43, wire 44, contact 12b, plug wire from TI to 16, wire 15, brush 26, through a right side marginal perforation to plate 21, wire 33, switch 35 and wires 64 and III to line iii.

The disengaging magnet 24 is in addition connected, by one of its terminals, to a wire 41 leading to one terminal of disengaging relay 48, the other terminal of which is connected, by a wire 49. to bus bar 39. Said magnet 24 is connected, through its other terminal, to a wire 50 leadin to one of the terminals of engaging magnet 2|. Disengaging relay 4!, when energized, closes a contact 48:: one of the terminals of which is connected to wire 41 and the other terminal of which is connected to a wire 8| connected to a contact 24a. which is normally closed (the breaking of which is controlled by the energizing of magnet 24) and to a wire 52 leading to plate 21. A condenser 53 is generally provided as a shunt in relation to contacts 48a and 24a in order to of said contacts.

One of the terminals of engaging magnet 2| is connected to wire 54; its other terminal is connected to a wire 54 leading to a twin plug socket 55 which can be electrically connected by means of plug wire connections either to socket 56 relative to the minor control, or to a socket B, or to both of these.

Socket 58 is connected, by a wire 59, to a cam contact L33 which is adjusted to close for a moment between the passage of the cards and after the printing of each line, said cam contact being moreover connected, by a wire ill, to one of the terminals of a contact 61b (controlled by electromagnet 81 positioned on the minor control circuit, as will be seen later), the other terminal of which is connected by a wire 42, to line HI and by a wire 64 to switch 35; said contact 61b may be short-circuited by a switch 65 which is closed when the machine is operated only for listing and which is opened when the machine is operated with automatic control. Socket it of the minor control is connected, by a wire 66, to a contact 61a which is closed when magnet 61, which controls it, ceases to be energized (said magnet being positioned as will be explained later, in the relay circuit of the minor control) and which is connected, in addition, by wires 88 and 68a to a cam contact Pll designed to be closed after total printing, said cam contact being connected by awire B9 to line I.

A circuit through wire 68a includes a contact 430 (the closing of which is controlled by the energizing of coil 43 hereinabove mentioned), a wire ll, one winding of double wound relay l2 and a wire H which leads to one of the terminals of contact 30a and to wire 38. Said double wound relay [2, the second winding of which is positioned in another circuit leading from bus bar 39 to wire 5|, controls a contact 120. which closes when the first mentioned winding of the relay in question is excited; said contact is placed on the same circuit as the second winding of double wound relay 12 inserted between wires 13 and 14.

Right hand brush 2G is connected, by wire 15, to a double socket Ii which may be connected, by means of a plug wire connection, to a socket 11 which is connected to a contact 12b, the breaking of which is controlled by the energizing of double wound relay 12, said contact 12b being arranged in series relatively to coil 42 of the relay corresponding to the progressive total and to coil 43 mentioned hereinbefore.

When it is desired to control the engagement of the paper feed by means of a perforation swept by brush 25, the socket I6 is connected by a plug wire to a socket l1 wired to a relay 43', said relay being itself connected by a wire and a resistance to bus bar 39. When energized, relay 43' closes a contact 43'd, one terminal of which is connected to coil 43' while the other terminal is connected by a cam contact L33 (adjusted to open at the same time as cam contact L33) and by wires to plate 21. Coil 43, when energized, likewise controls the closing of a, contact 43'!) shunted in relation to the combination of sockets 55 and 58.

Moreover, according to the invention, in the customary circuit of stop key contacts 15' (see Fig. 10A) is positioned a contact 301) which is normally closed but which opens when stop relay all (see Fig. 10) is energized, that is to say, when brush 28 makes contact with plate 21, in other words, when there is no more paper to be passed over printing roller 2; the breaking of said contact 30b breaks the circuit of the stop contacts in which is also positioned the usual engaging magnet 22! of the card feed device as well as start relay 18 which starts and holds the energization of said magnet. When there is no more paper to be supplied to roller 2 the card feed device is therefore disengaged and the card feed of. the machine is automatically stopped in consequence.

In the same circuit as the stop contacts 16' is positioned a three blade contact 4311 which normally occupies the position shown in Fig. 10A, with its upper contacts normally closed in series with start relay 18 holding magnet 22! engaged, but the central blade of which is moved to open upper contact 43b when a feed control magnet 43 is energized. The circuit which initiates the effectiveness of the card feed clutch magnet 22f while the tabulator is operating, may be traced through line 330,'cam contact Pl, magnet 22). relay 340, relay 1!, switch 353, cam contact P2, card contact LCLa, stop key contact 16', contact 30b, upper contact 43b, lower contact 3380 closed by control magnet 82, and line 33!. This circuit is again initiated if the upper contact 43b is held closed. Said contact 431) has been provided in order to deenergize relay Ill which would otherwise tend to hold the energization of the card feed engaging magnet between the printing of one progressive total and the printing of a carry forward of said total on to another form. Magnet 43 is energized, to open upper contacts 43b when brush 2B encounters a marginal perforation, in order to stop card feeding and in order 5 to prevent the feeding of cards between said two consecutive printings of progressive totals, as will be seen from what follows.

Magnet 42 related to the taking of a progressive total, also causes, when energized, the closing of a contact 42a shunted in relation to contact P3 (see Fig. 10A) when switch 19 is closed, said switch beingclosed when it is desired to print on the forms, accounting items with progressive totals. The first progressive total is initiated by directing a circuit through the auto reset relay 34! which in turn activates the reset clutch magnet 80 and the motor RM. The circuit through relay 348 includes line 330, contact 420, switch l9, relay 348, cam contact L3, switch 346, lower 20 contact 43b (closed because relay 43 is energized at the same time as relay 42) lower contact 338a and line III. Relay 348 then closes contact 348a to energize magnet 80 and establish a holding circuit. The holding circuit passes through line at, contact P3, magnet 348, contact 348a, to line "I. At the end of the cycle, contact L4 closes completing a circuit from line 330, contact p3 and 384e, clutch magnet 80. contact L4, contact 248a and line "I. Magnet 80 then operates a lever to close contacts 281 in shunt around contact P4. Then the reset motor RM and the zero control magnet 350 are energized and a total printing operation is effected, but resetting of the accumulator is prevented. 'A second cycle of totaling is induced by the continued closure of contact 420. Said contact 42a remains closed during the time relay 42 is energized, said period of energizaticn being regulated by the duration of the closing of cam contact Pia (see Fig. 10); 40 the setting of the cam of said contact is such that magnet 42 remains energized sumciently long and that contact 420 may in consequence be closed long enough to carry out two successive total taking cycles (whereas the duration of the 5 closing of P3 is such that normally a single total taking cycle is eflected through the magnet III which controls engagement of the total print mechanism with the reset motor RM) making it possible. in the case of progressive total selection,

t to print said progressive total and then to print the carry forward of said total on the following iorm.- Near the end of the first total printing cycle, feeding of the record sheet is initiated by the momentary closure of contacts Pl I, Fig. 13, but immediately before this, contacts Pia open momentarily, and close again before brush 26 is insulated from plate 21 by the sheet which starts to move. Therefore, magnet 42 is again energized to close contacts 42a and initiate a sec- 0nd progressive total printing cycle. Near the. end of this second cycle, contacts Pia again opeh" and close, and this time magnet 42 becomes deeners'lzed because brush 28 has been insulated by the shifted record sheet.

The closure of contacts 420 serves to make magnet 80 effective longer than usual. When contacts P4 open at the end of the total print cycle, the reset motor circuit is not broken as it is usual- 1y, instead a shunt comprising contacts 2" held closed by magnet 80 maintains reset motor operation for another cycle.

As shown in Fig. 10A, a magnet 6l.is inserted in the circuit of relay ll of the minor control which also includes relay l2 controlling the tabulating motor. The excitation of magnet ll causes the breaking of contact "a hereinabove mentioned (see Fig. 10) and also opening of contact 61b. In addition, relay ll of the minor control, controls contact Ila. the blade of which is connected as usual to bus bar ll leading to main line I",

which components exist in the tabulating machines already known. Contact Ila assumes the position shown in Fig. 10A when relay 8! of the minor control is not energized. Instead of using coil BI and the associated connections in the minor control circuit, similar connections may be inserted in the major control circuit, if such controlis desired.

In order to prevent resetting of the accumulators while totals are printed as at I and I". Fig. 3, a switch 84, Fig. 10A, is provided to open the connections leading to the reset magnet I82, thus preventing resetting of the accumulators. This switch 94 when opened causes the taking of progressive totals, after which it may be closed to allow magnet I82 to be energized fora clearing total.

The same progressive totaling form of control 5 may be obtained in another way with switch 94 held closed. Then the dial switch is set at "Prog," but turned to Min" after progressive totals have been recorded. The auto restart switch 353 may be opened so that the machine is stopped after each progressive total printing cycle so that the operator can turn the dial switch to "Min" and press the reset key whenever he desires to take a clearing total.

The diagram of the circuits and of the moditlcations which are made in the electric connections of the tabulating machine having been described hereinbefore, the operation of the devices which form the subject matter of the invention will now be explained with reference to various typical cases such as those indicated in the ob- Jects of the invention.

Assuming first of all that it is desired to print on each form (an invoice for instance) a single line from each of a series of cards passing through the machine operating in listing, each line of print containing the particulars of a single card on each form and the feed of the paper having to occur between each line printed. This is the case represented in Fig. 1. In said figure, the arrow indicates the direction of travel of the paper forms. In the case considered, a single perforation on the left hand side is necessary on each form this is the perforation shown at a. In addition, special switch 65 (Fig. 10) is closed (in addition to switches Ii and 3B which are always closed when it is desired to operate the feeding devices) and a plug wire connection is made between socket 58 and socket 88. Finally, the position of the left hand brush 2! (see Figs. 6 and 10) is so adjusted that perforation a shall appear under said brush when the location for printing on the preceding form is beneath the printing ribbon against which the type impinges. For instance, referring to Fig. i, the adjustment of the position of brush 25 is such that when perforation a is beneath brush 24. line 1 on which the printing of the previous form is to take place, is in the printing position.

Referring now to thediagram of the circuits represented in Fig. 10. it will at once be seen that as soon as the line of print I has been printed, engaging magnet 2i of the paper feed device is en-- ergized by the establishing of the following circult: line 830, switch 3|, wire 20, contact 30a, wire 38. wire 50. magnet IL'WN i4, socket Ii,

'group of cards, the

plug connection leading to socket 58, wire 55, cam contact L33 closed at this moment, wire 55, switch 55, wire 52, and line 331. The setting up of this circuit occurs due to the closing of contact L33 which is so adjusted as to close for a moment between the passage of the cards and after the printing of the line. The paper feed device being thus engaged after the printing of line 1, the paper travels forward until said device becomes disengaged, which is brought about by means of perforation a, the position of which is such that it causes the stoppage of the paper at line 1' (see Fig. 1). This disengagement of the paper feed device is obtained by means of magnet 24 which is energized long enough to cause said disengagement. The energization of magnet 24 is sustained momentarily by an impulse carrying circuit set up by a relay 45 which is energized at the same time as magnet 24 when sensing brush encounters a perforation a. When perforation a arrives under brush 25 the following circuit is established: line 335, switch 3|, wire 25, contact a, wire a, wire 45, relay 45, wire 41, wire 31, brush 25, plate 21-21, wire 33, switch 35, wires 54 and 52, and line 33L At the same time, magnet 24 is energized by a circuit through line 330, switch 3|, wire 23, contact 30a, wire 35, magnet 24, wire 31, brush 25, plate 21-21', wire 33, switch 35, wires 54 and 52 and line 331. Then, with both relay and magnet 24 energized, the relay closes contact 4511 and the magnet opens contact 2411; but the contact operation is not simultaneous, because contact 450. is quick to close and contact 24a is slow to open, therefore there is an instant that magnet 24 is energized independently of the brush circuit. Energization of relay 45 during the short period that the perforation passes under the brush, quickly causes the closing of contact 4501 which is coupled to it and the setting up of the following impulse circuit for momentarily holding the energization of the disengaging magnet 24; line 330, switch 3|, wire 23, contact 35a, wire 35, magnet 24, wire 41, contact 4541, wire 5|, contact 24a, wire 52, plate 21-21, wire 33, switch 35. wires 54 and 52, and line 33!. Consequently, magnet 24 is energized sufficiently long, even after the perforation is no longer beneath brush 25, for the paper feed device to be declutched; in other words, perforation a has caused the stoppage of the feed of the paper with line 1' in the printing position so that the particulars corresponding to the next card may be printed at this spot. The contact 24a is soon opened by the energized magnet 24 and then both relay 45 and magnet 24 are deenergized because brush 25 is separated from plate 21 by the record paper. Contact 240 finally resumes the normal closed position when magnet 24 is deenergized.

It will now be assumed that the machine is functioning with automatic group control and that on each printed form it is desired to print a variable number of lines corresponding to one printing l f the total appearing beneath the lines previously printed on the form. In this case, represented in Fig. 2, a single perforation is still necessary, namely, perforation a on the left hand side of each form. In addition, switch is open and a plug connection is made between socket 55 and socket 55 corresponding to the minor control.

Engaging magnet 2| in the example under consideration becomes energized after the printing of the total on the closing of cam contact PM (see Fig. 10). the cam of which is so adjusted that the contact closes after the printing of the total. The energizing circuit is as follows: line 330, switch 3|, wire 29, contact 30a, wire 38, wire 55, magnet 2|, wire 54, socket 55, socket 55, contact 51a closed at this moment owing to the deenergization of the control relay 51, wire 65, wire 55a, contact Pl wire 55, and line 331. After energization of magnet 21, the paper feeds forward until perforation a stops the paper with line l of the preceding form in the printing position (see Fig. 2). The operating circuits of disengaging magnet 24 are in every way similar to those described in connection with the preceding case and need not be described anew. Said disengaging magnet 24 functions, as has been seen, owing to the passage of perforation a under brush 25.

It will now be assumed that the list of items of one group of cards is too long to be printed on a single sheet and that it is necessary to use several forms with a progressive carry forward on each form. In such case, several successive forms will be completed, the last form corresponding to a group of cards under consideration comprising the final general total positioned below the last line of accounting items placed on the list. As seen in Fig. 3, it is necessary to employ two perforations, one located on the left, perforation a, working in cqoperatio'n with brush 25, and the other located on the right, perforation b, working in cooperation with brush 25 (see Figs. 6 and 10) Perforation a is intended to stop the feed of the paper so that the first line of the preceding form shall be in the printing position. Perforation b is utilized to cause the stopping of the paper and the printing of a progressive total at the bottom of the preceding form. The right hand brush 25, which cooperates with perforation b, should be adjusted in such manner that it comes into contact with perforation b when the line before the last line of the preceding form is under the printing ribbon. Left hand brush 25 will be adjusted as in the preceding case.

In addition, the connections to be made in Fig. 10 are as follows; switch 55 open, a plug connection made between socket 55 and socket 55, and a plug connection made between socket 11 and socket 15. When perforation 1: comes under brush 25, the following circuit will be established: line 335, switch 3|, wire 23, contact 30a, wire 350, bus bar 33, wire 4|, relay 42, coil 43, contact 12b normally closed, socket l1, plug connection leading to socket 15, wire 15, brush 25, plate 21, wire 33, switch 35 closed, wires 54 and 52, and line 33!. Consequently, progressive total relay 42 is energized; a holding circuit is moreover established by contact 43a which is closed owing to the energizing, of coil 43. This holding circuit, which continues from coil 43 up to line 33! and which includes contact 430, wire 45, cam contact P50. and wire 45, maintains the progressive total relay 42 energized even after perforation b is no longer under brush 25. The duration of the closing period of contact PM is adjusted in such manner that magnet 42 controlling contact 420. of the progress ve total circuit (see F g. 10A, with switch 15 closed when the device is operated with a taking of progressive totals) makes it possible to carry out two successive total taking cycles and consequently two printings of the progressive total, one at the bottom of one form and the other on the first line of the following form as explained hereinbefore. Upper contact 43!) (see Fig. 10A) controlled by coil 43 (see Fig. 10) opens to deenergize relay 13 for disengagement of the card feed device and thus stops card feeding and prevents the feeding of cards in the machine between the two prlntings of the progressive total at the end of one form and at the beginning of the following form.

In addition, the energization of coil 43 causes the closing of contact no and in consequence the energization of magnet 2| for engaging the paper feed device after the printing of the progressive total owing to the establishing of the following circuit: line 333, switch 3|, wire 29, contact 30a, wire 38. wire 50, engaging magnet 2|, wire Ha, wire ll, contact 43c, wire 33a, cam contact Pl I, wire 83, and line 33 I. Thus. after the printing of the progressive total at the bottom of the form at 1', said printing occurring owing to right hand perforation b on the following form, engaging magnet U is energized and the sheet of paper is fed forward until it is stopped by perforation a of the form which is behind it, the position of brush :5 being adjusted in such a way that said perforation a stops the form preceding it with line 1" in printing position. The circuit through which disengaging magnet 24 becomes energized and the sheet of paper is stopped when line I" is in the printing position (the progressive total being carried forward to this line owing to the duration of energization of magnet 42) will be through brush 23 the same as in the previous instances. Therefore, it is not necessary to describe it anew.

During the first progressive total printing cycle, brush 23 (Fig. projects through perforation b and maintains relay 42 energized even though cam contact PGa opens for a short time near the end of the operation. At the end of this first cycle, paper feeding takes place and the brush 26 is insulated, but contact Plic has again closed to hold the energization of relay 2. 0n the second progressive total printing cycle, after printing has occurred, contact Pia again opens and then relay 2 is deenergized. Contact 420 (Fig. 10A) then opens to deenergize relays 33 and 343, thereby causing contacts 231 to open, and later in the second cycle, contact Pl opens to deenergize the reset motor RM.

On the form coming next (which form commences at line I" by the carry forward of the progressive total (see Fig. 3) will be inscribed other related accounting items and, if there is no change in the group of cards, a progressive total will be printed at the bottom of the form, as has previously been explained. 11, on the contrary, a minor or major change of group occurs in the interval, the total will be printed and the paper will feed after the printing of said total up to the first line of the following form exactly as in the case previously considered. The last mentioned total will also be a progressive total unless the operator intervenes to close switch 93, Fig. 10A, or shift the dial switch to Min. But, in order to avoid the reenergization of relays 42 and 43 in this latter case by the passage of the perforation in front of the right hand brush during the feed after the printing of the major or minor total, provision has been made. as indicated in the previous general description, of double wound relay 12. the purpose of which is to break contact 12?) which is situated in said circuit of brush 33. which breaks the circuit of progressive total relay 42 and of coil 43. The energlzation of double wound relay I2 is caused by the following circuit: line 333, switch 3|, wire 23. contact 30a, wire ll, double wound relay 12, wire Ila, wire 54, socket ii, plug connection leading to socket 36, contact 31c closed owing to the operation of the group control, wire 33 and wire 3311, cam contact Pi i, wire 33, and line III. A holding circuit for relay I2 is established by the closure of contact 12a.. The circuit may be traced through line 330, switch 3 i, wire 23, contact 30a, wire 33a, bus bar 39, wire I4, holding coil 12, contact 12c, wires 13 and 5|, contact 24a. wire 32, connection 21', wire 33. switch 33, wires 34 and B2, and line 33L This circuit is maintained during feeding until con tact 24a is opened by energization of magnet 24 brought about when brush 2i encounters a control perforation.

It will now be assumed that the total is to be printed at the bottom of the form irrespective of the number of lines listed on said form. This is the case represented in Fig. 4. Under these conditions it is necessary to provide two perforations on .the left hand side of each form and to establish a plug wire connection between double socket $5 and socket 58 and another plug wire connection between double socket 55 and socket 56, switch 65 being open as before. In this manner, two feeding operations of the paper may be obtained; one feed which occurs with the functioning of the major or minor control and which is arrested by the first perforation c of the next form for the printing of the total at the bottom of the form (referring to Fig. 4, perforation 0' will stop the paper with line I of the preceding form in the total printing position) and a feed which occurs after the printing of said total and which is arrested by perforation a of the form (for instance, if Fig. 4 is considered, perforation a will stop the pap r, after the printing of line 1, with line i in the printing position).

Distance A (Fig. 4) between the two perforations on any one form must obviously be equal to distance B included between the line on which the total is printed and the first line of the following form as will readily be understood.

As already explained, it is necessary that after the printing of the last line listed on a statement, and prior to the printing of the total, a forward feed should occur, that is to say that engaging magnet 2| should be energized, and this occurs through the following circuit: line 330, switch 3 I, wire 23, contact 30a, wire 33, wire 50, magnet 2 I, wire 54, socket 55, plug connection leading to socket 53, wire 39, contact L33, wire 60, contact 31b, wire 62 and line 33!. It has been explained that contact L33 is adjusted in such manner as to be closed for a moment between the cards and after the printing of each line; also that contact no closes on account of the functioning of the major or minor automatic control; a feeding operation therefore occurs after the functioning of the control and prior to the printing of the total. Said feed is arrested by the first perfora tion 0 of the following form when said perforation arrives beneath brush 25 to energize the disengaging magnet 24 and at the same time enersizes the sustaining relay magnet 43. Then the following circuit is established: line 330, switch 31, wire 23, contact 30a, wire 38a, wire 49, magnet 43, wire 41, wire 31. brush 25, plate 21-41, wire 33, switch 33, wires 34 and G2 and line 33L Relay 43 being energized, contact 43a closes and the following circuit is established: line 330, switch 3!, wire 29, contact 30a, wire 38, magnet 23, wire (I, contact a, wire 5|, contact 24a, wire 32, plate 21-41, wire 33, switch 35, wires 64 and 32 and line 33L The paper is thus stopped just before printing occurs with the last line, 2, of the form in printing position,

The total is printed and immediately after, a

further feeding operation occurs owing to the onergization of engaging magnet 2| due to the establishing of the following circuit: line 330, switch 3|, wire 29, contact 30a, wire 38, wire 58, magnet 2i, wire 54, socket 55, plug connection leading to socket 56, contact 51a, wire 68, wire Gila, cam contact PI I, wire 69, and line 331. The adjustment of cam contact PH is such that said contact closes after the printing of the total. This further feed of the paper is then stopped by the second perforation (I'Of the form so that said paper is stopped with first line 1' of the form in the printing position. The circuit for stopping the feed of the paper is the same as in the preceding cases: it is therefore not necessary to describe it anew.

Finally it will be assumed, in the last example, that it is desired to print the items of a group cf cards on several forms. This is the case shown in Fig. 5. It will be seen that it is necessary to employ two perforations in this case: perforation a positioned on the left and cooperating with brush 25, and perforation b positioned on the right and co-operating with brush 26. Perforation 17 makes it possible to obtain a paper feeding operation after the printing of the last line of the form. Perforation a is utilized to stop the feed of the paper after the feed subsequent to said printing, with the first line of the form in the printing position. For the continuation of item printing it is necessary to establish the following connections: close switch 65, plug connection between socket 55 and socket 58, plug connection between socket I6 and socket 11'. Under these conditions, when perforation b arrives beneath brush 25, the following circuit will be established: line 330, switch 3|, wire 29, contact 300, wire 38a, bus bar 39, coil 43', socket I1, plug connection leading to socket 16, wire 15, brush 28, plate 21, wire 33, switch 35, wires 64 and 52 and line 33L As coil 43' is energized, contact l3'a will close, maintaining the energization of coil 43' through the following circuit: bus bar 39, coil 43', contact "'11, cam contact L33 closed at "1 and held c osed until after printing, wire 33, switch 35, wires N and B2 and line 33L The energization of coil 43 determines the closing of contact 43'!) which establishes the circuit of engaging magnet 21 and therefore causes the feeding of the paper when contact L33 closes, that is to say immediately after the printing of the line. Should the account call for the printing of the total before the end of a form is reached, then sheet feeding is initiated after total printing by the energization of engaging magnet 2i through a circuit including line 330, switch 3|, wire 29, contact Illa, wires 38 and 50, magnet 2|, wire socket 55, plug wire to socket 58, contact 61a, wires 68 and 88a, cam contacts Pl I, wire 59 and line Ill. The feeding operation will be arrested by perforation a so that the first line of the following form will be in the printing position. The termination of the paper feed under these conditions occurs in the same manner as in the cases previously described, making further explanation unnecessary.
