29 Claimsl This invention concerns accounting and the like machines, particularly machines having trayeling carriages, and relates primarily to a presettable selective carriage return control mechanism for such machines.

CTI

A type of work for which such machines are f intended involves the posting of lines oi' entries on columnar forms having at least one column for data, the presence or absence of which, and the character of which, if present, is determined by the character oi' an entry in the same line in a nonadjacent preceding column. One example of such work is the posting of customers checking accounts in banks wherein the amount of the old balance is entered in an old balance column at the beginning of a line of postings, then the amount or amounts of one or more checks drawn against the account is or are entered in one or more check columns and/or the amount of a deposit to the account is entered in a deposit column, and the amount of the new balance is printed in a new balance column. The columns are arranged on a main portion of the form from left to right in the order mentioned above.

In present bank practice, it is necessary to produce analyses of customers checking accounts to determine when and what charges should be made for handling the accounts to prevent loss or insure a predetermined minimum profit for the bank. For example,\the portions of the daily balances of customers accounts which are available for the use of the bank are dependent upon what portions oi such balances remain after deducting credited amounts which are in collection and not yet received by the bank. For that pur pose, the form `is provided with a second new balance column to the right of the main portion of the form and with an analysis column at the right of the second new balance column. On the customer's statement form, a line of perforations may be formed between the two new balance columns to permit the portion containing the second new balance and analysis columns to be detached from the statement before the latter is delivered to the customer.

The data to be posted in the analysis column` in any line of postings, in this example of work,

is determined from the nature of the entry posted in the depositcolumn 'in the same line, and may consist of the amount of any items, such as checks on other banks, which are included in the entry posted in the deposit column but which will not be available for the use of the bank until co1- lected. When no entry is made in the deposit column in a line of posting, or when the entry in the deposit column represents solely currency or checks drawn on the same bank, there will be no entry to be made in the analysis column and time can be saved and the work output of the machine and operator can be increased if the traveling carriage of the machine can be returned to its starting position for a new line of postings immediately after the printing of the new balance in the column preceding the analysis column and without tabulating into `the latter column and so requiring theperatcr to act, as by depressing a motor bar to give the machine a blank operation, to cause the carriage to be returned without -an entry being made in the analysis column.

The present invention provides an improved means to permit the machine operator, at the time of operating the machine, to print an entry in the deposit column, or at the time of operating the machine to print an entry in a preceding column in case no entry is to be printed in the deposit column, t0 control the conditioning of a means to cause the carriage automatically to be returned after the printing of the new balance in the column preceding the analysis column, in case no entry is to be printed in the latter column, or permit the carriage to tabulate to the analysis column if an entry is to be printed there, said means also adapting the machine for other work requiring such a presettable selective Control of the carriage return.

An object of the present invention is to provide a machine of the class mentioned above with an improved presettable selective carriage return means. A further object of the invention is to provide a machine oi the class mentioned above with a presettable selective carriage return means of simplied construction and reduced Cost.

A further object of the invention is to provide a machine of the class mentioned above with a presettable selective carriage return means which will render the machine adaptable to the greatest number of varieties of work with the minimum of interference with other devices and mechanisms which may be included in the machine for the work involved.

The drawings show an embodiment of this invention as'applied to the `well-known Burroughs high keyboard machine illustrated in many patents, as, for example, the Pasinski Patents Nos. 1,778,506 and No. 1,911,768, for which reason the general construction of the machine will be described only briefly, reference being had to the foregoing and other issued patents for further details of the general construction. It will be obvious to those skilled in the art that the invention may be applied to other types of calculating machines.

General construction from a motor bar M. The front and rear stems of said motor bar M are supported on studs on levers`21 and 28 (Fig. ,6) pivoted on shafts 28 and 30, respectively, and having a stud and slot connection 3l with each other between said pivots. The levers 21 and 28 are urged clockwise and counterclockwise, respectively, by a,spring 32 connected between said levers and thus urging the motor bar M upward to normal position. The rear end of the lever 21 has a stud 33 (Fig. 10) engaging in a slot in a control link 34. A spring 35 is connected between the lever 21 and the link 34 to urge said link upwardly relatively to said lever and tends to maintain the stud on said lever at the lower end of the slot in said link. The lower end of the link 34 passes through an opening in a stud 36 pivotally secured in the end of an arm 31 through which the usual clutch and motor switch are controlled as shown in said Bindschedier patents. A spring 34a surrounding the link 34 and compressed between a shoulder on said link and the arm 36 urges the link and arm upward and downward, respectively, relatively to each other to the limit determined by nuts threaded on the lower end of the link.

`.Depression of the motor bar M rocks the levers 21 and 28 counterclockwise and clockwise, respectively, and the rear end of lever 21 acting through the spring 35 raises theV link 34 and the forward end of the arm 31 to close the motor switch and connect the clutch to give` the machine a cycle of operation. The levers 21 and 28 are latched in their rocked positions, as in Fig. 6, to hold the motor bar M depressed, by the usual repeat hook" or latch 38 which is pivoted on the lever 28 and spring urged clockwise into latching engagement with a stud-39 on the rear arm of the lever 21.

For each cycle, the clutch shaft 40 (Fig. l) and the crank arm 4| thereon rotate one revolution and, through the link 42, rock an arm 43 first clockwise and then counterclockwise about a shaft 44 on which said arm'is freely rockably mounted. The arm 43 has an abutment cooperating with an abutment on an arm 45 secured on the shaft whereby the arm 43 when driven clockwise also drives the arm 45 and shaft 44 clockwise in what -is known as the forward stroke of the cycle. An arm 4B also secured to the shaft 44 is connected to-springs 41 which return the shaft 44 and arms 455 and 46 counterclockwise in the return stroke of the cycle while the motor, clutch and arm 43 generally run somewhat ahead of the arm 45. The arm 46 is connected through` a link 48 (Figs. 1 and 6) to the usual full-stroke sector 49 secured on the shaft 58 to which the usual hand crank may be attached for cycling the machine manually when desired.

The full stroke sector 49 is rocked counterclockwise in the forward stroke and returned clockwise in the return stroke of each machine cycle. The upper rear edge of the full stroke sector 49 is normally engaged by the lower arm of a three-armed lever 55 (Fig. 6) pivoted on a xed stud 56 and pivotally carrying on the end' of its rearward arm two pass-by pawls 51 and 58 (Figs. 4 and 6) urged clockwise by individual springs 59 whereby the three-armed lever 55 is also urged to rock clockwise `as the full stroke sector 49 rocks counterclockwise in the forward stroke of a machine cycle. lever 55 is permitted to rock clockwise to the extent of its longest stroke, both pawls 51 and 58 are carried past a roller 6D carried on the lower end of one side arm of the usual keyboard release bail 6| pivoted on a shaft 62 and urged clockwise to the position shown in Figs. 1, 4 and 6 by a spring 63, the springs 59 permitting the pawls 51 and 58 to yield without rocking the bail' 6|. Then, during the return stroke of the cycle, the full stroke sector 49 returns the threearmed lever 55 counterclockwise to normal, causing the long pawl 58 to cam the roller 60 rearwardly and thereby rocking the bail 6| sulfieiently not only to release depressed keys but also to cause the upper end of its right-hand side arm to move a slide 64 supported on the lower keyboard plate forwardly against the tension of a spring 64a (Fig. 6) to engage a lateral lug85 on said slide with an upward projection on the latch 38 and rock the latter to release the levers 21 and 28 whereupon the latter and the motor bar M are restored to normal by the spring 32. Should the operator continue to hold the regular motor bar M depressed, either directly or through either the upper or the lower motor bar U or L as described later, at and after the time the repeat hook 38 is released from the stud 39 by the projection 65, a detent 66 pivoted on the stud 38 is rocked counterclockwise by a spring 61 to position a shoulder 58 on the upper one of two rearwardly extending arms thereof in front of a stud 69 on the repeat hook 38 to hold the latter in releasing position until the motor bar Mis permittedto restore to normal whereupon the stud 39 in lever 21 depresses the lower arm. of the detent 66 to disengage the shoulder 68 from the stud E9.

During the forward stroke of each machine cycle. a stud 18 (Fig. 4) on the full stroke sector 48 engages a projection 1| on the control link 34 and returns the latter downward somewhat below its normal position, thereby carrying a stud 12 on the link 34 below the lower end of a latch pawl 13 pivoted on a fixed stud 14. A spring urges the pawl 13 clockwise to engage a forward projection of said pawl against the stud .39 and to position the lower end of said pawl above the lowered stud 12 to prevent the control link 34' from moving upwardly far enough to initiate another machine cycle as the full stroke sector 4s and stud 18 return to normal in the return stroke of a machine cycle. When the lever 21 returns to normal after release of the latch 38, the stud 39 dcprcsses the forward pro- If the three-armed` ski Patents 1,778,506 and 1,911,768.

' 9| to lock the lower jection of the pawl 13 and swings the lower end of said pawl rearwardly ofthe stud 12 so that the control link 34 is free to rise upon the next depression of the motor bar M.

A bell crank 88 (Figs 1 and 4) pivoted on a stud 8| carried by the stem 82 cf an upper motor bar U has in its forward arm a slot which receives a stud 83 carried by the rear end of the lever 28. The parts are normally positioned as in Fig. 1. When the regular motor bar M is depressed, the bell crank is rocked counterclockwise to place the end of its lower arm above a fixed squared stud 84 on which the stem 82 is slidably guided, whereby the upper motor bar U is locked against depression until the regular motor bar M returns to normal. When the upper motor bar U is depressed, a stud 85 secured in the stem 82 engages the upper edge of the forward arm of the bell crank 88 to prevent clockwise rocking thereof and thereby causes the regular motor bar M to be depressed with the upper motor bar and latched down by the repeat latch 38. The ehd of the lower arm of the bell -crank is then positioned in frontof the stud 84, whereby the upper motor bar U is latched in depressed position until the regular motor bar M returns to normal.

The stem 88 (Fig. l) of a lower motor bar L has an arm 81, the upper rearward end of which is positioned over a stud 88 carried by the forward end of the lever 21 so that depression of the lower motor bar L also causes the regular motor bar M to be depressed and latched down by the repeat latch 38. The slotted end of the upper arm of a bell crank 89 pivoted on a stud 98 secured in the stem 86 receives the stud 88. When the lower motor bar L is depressed, thc end of the ower a-rm of the bell crank B9 is moved down behind a xed stud 9| whereby the lower motor bar L is latched down until the regular motorv bar M returns to normal, but when the motor bar Mis depressed without depressing the lower motor bar L, the end of the lower arm of the bell crank 89 is positioned over the stud motor bar aga-inst depression until the regular motor bar M returns to normal.

Thus the upper and lower motor bars U and L, when depressed', initiate machine cycles by causing depression of the regular motor bar M and elevation ofthe control link 34. They also perform further functions which will be described later.

The amount entering means of the illustrated machine comprises .a suitable number of rows or banks of keys 85 (Figs. l and 3) which, when depressed, rock individual bell cranks Q6 which move stop wires 81 into position to arrest the amount actuator sectors 9 8 (Fig. 1), associated with the several banks or keys, .atpositions corresponding to the depressed keys in the respective key banks when said actuators descend from their normal positions during the forward stroke of the cycle. During the return stroke, the lowered actuators 98 are raised again to their normal positions by the usual bail (not shown) and the depressed keys 85 are restored to normal.

The illustrated machine has a main adding and subtracting totalizer or crossfooter of the tumbling type having a plurality of pairs of meshing pinions 88 and |88 (Figs. l and 3). This main register or crossfooter is constructed and operated substantially as disclosed in Pasin- The pinions 99 and |88 are supported in a tumbling frame |0| (Fig. 3) pivotally supported by studs |02 in a main irame Ill rockably mounted on the shaft Ill. The tumbling frame lll is normally positinned so that. when it is moved toward the actuators 98, by rocking of the main frame |03 about the shaft |04, the add pinions 99 of each pair of pinions 99 and |00 will mesh with the corresponding actuators but the frame may be tumbled to cause the subtract pinions |00 to mesh with the actuators upon movement of the frame Ill toward the actuators. For amount entering operations, i. e., addition or subtraction, the pinions 99 or |00 are out of mesh with the actuators 98 throughout the descent of the actuators but the pinions are in mesh with the actuators during their return to normal in thereturn stroke of the amount entering cycle so that amounts entered on the keys 95 will be entered inw the register. In total-taking operations, the plnions 99 or |00 are in mesh with theactuators during the forward stroke of the total-taking cycle and the actuators 98 descend until the corresponding pinions are arrested. The pinions are disengaged from the actuators while the latter rise again to their normal positions during the return stroke of the total-taking cycle. In subtotal-taking cycles,'the pinions 99 or |00 are meshed with the actuators during both the forward and return strokes so that the total withdrawn from the totalizer in the forward stroke is reentered during the return stroke. In adding, positive total taking and positive subtotal taking, the pinions 99 are meshed with the actuators 98 but, in subtracting, negative total taking and negative subtotal taking, the pinions |00 are meshed with the actuators.

.For the add-subtract totalizer 99--|00, there is a tens-transfer mechanism effecting both carries and borrows by means of an extra step of return movement of the actuators 98 beyond their normal positions as disclosed in the Rinsche Patent No. 1,172,484. Portions of this transfer mechanism arrest the totalizer pinions in their positive "0 positions in positive total-taking and positive subtotal-taking operations and in their positive 9 positions in negative total-taking and negative subtotal-taking operations. A "fugitive 1 mechanism also like that disclosed in the Rinsche Patent No. 1,172,484 is provided to enable numerically correct negative as well as positive totals to be obtained.

The illustrated machine also has a multiple` register line comprising a plurality of adding registers |05 (Fig. l) constructed and operated as disclosed in the Pasinski Patent No. 1,911,768 and provided with a tens-transfer mechanism also like that disclosed in said Pasnski patent and in the Pasinski Patent No. 1,774,289. The registers |05 are out of engagement with the actuators 98 while the machine is at rest.v

The printing mechanism in the illustrated machine is of the general type disclosed in W. S. Burroughs Patent No. 505,078 and comprises, for each actuator and corresponding bank of keys, a set of printing type |06 (Fig. 1) carried on the rear arm of the lever |01, the forward arm of which carries the actuator 98. Thus, at the end of the forward stroke of a cycle, the types |06 corresponding to the amount entered on the keys l 95 or the total or subtotal taken from the crossfooter 99|00 or from a register |05 are positioned at the printing line. These type are then driven by hammers |08 (Fig. 1) against record material held about a platen roller P.l The printing hammers are controlled, as in the usual machine of the type illustrated and as disclosed in various patents, to secure the desired printing in selected orders.

Printing is effected in selected columns on the work sheet, the selection of columns being controlled by columnar printing control means which, in the iorm provided in the illustrated machine, comprises a traveling carriage C carrying the rotatable platen P and longitudinally movably mounted on raceways at the rear of the fixed frame of the machine. The carriage .is urged toward the left, as viewed from the front of the machine, by a spring in a drum ||0 (Fig. 3) to which is secured one end of a tape III, the other end of which is secured to the carriage. Normally, the carriage tabulates toward the left from one columnar position to the next near the end of each cycle of the machine under the control of a tabulating mechanism like that disclosed in the Rinsche Patents Nos. 1,516,685 and 1,580,534. 'I'he tabulating mechanism comprises a stop bar l2 (Fig. 19) rockably mounted on the carriage4 and carrying a plurality of column stops H3 adjustably positioned along the bar |I2 in accordance with the columnar positions in which they are to hold the carriage by engagement with an abutment Ill. A tabulating pawl ||5 (Fig. 19) is pivoted on a slide LIB which moves downward during the forward stroke of each cycle, whereupon the pawl ||5 is normally permitted to be rocked counterclockwise by its spring to place its upper end under the active stop 1|3 so that when the slide ||5 returns upward during thev return stroke, the pawl H5 engages the active column stop ||3 and rocks said stop and the bar |2 to disengage said stop from the abutment IH. The carriage immediately moves toward the left as viewed from the front or toward the right as viewed in Fig. 19, and thereby carries the said stop ||3 away from the pawl I5 whereupon the bar ||2 normally is immediately rocked back to its normal position by the usual spring ||8 (Fig. 1) so that the stop 3 for the next column is in position to engage the abutment III and arrest the carriage in the next columnar position.

The carriage may be normalized, i. e., the tabulating mechanism may be disabled, by means of the usual Carriage normal key CN (Fig. 1) controlling means, such as disclosed in the Lundgren Patent No, 1,195,599 and including the slide ||9, which disables the tabulating mechanism and enables the usual line spacing mechanism and so permits the carriage to remain stationary and causes the paper around the platen to be line-spaced after the operation of the printing mechanism in each machine cycle as long as said key remains depressed. Also, the lower motor bar L, when depressed to initiate a machine cycle, will disable the tabulating mechanism. A stud |20 (Fig. l) Vsecured in the lower motor bar stem overlies the forward arm of a lever |2I pivoted on a xed stud |22. The rear arm of lever |2| has a stud and slot connection with the forward arm of a lever |23 pivoted on a fixed stud |24. A lever |25 also pivoted on the stud |24 is straddled by a pair of studs |20 secured in the lever |23 to rock lever |25 with lever |23. The rear end of lever |25 overlies a roller on a stud |26secured in the rear portion of )a link |21 pivotally connected to the full stroke sector 49 so as to be pulled forwardly in the forward stroke Vof each machine cycle and returned rearwardly in the return stroke of the cycle. The stud |28 extends through a slot in a rocking cam |28 pivoted on a iixed stud |29.. A spring (not l'26 upwardly and the lower edge of cam i523 depresses a roller stud llaa carried by the slide lili whereby the latter is depressed and enables the line-spacmechanisrn and disables the carriage tabung mechanism.

einen 'the lower motor bar L, after being depressed, is manually held fully depressed until r a predetermined point in the return stroke o the resulting machine cycle, the carriage remains in the same columnar position for the next machine cycle and the paper around the platen is line-spaced However, if manual pressure is withdrawn from the lower motor bar L .ceiore a predetermined point in the resulting l lachine cycle, and in any machine cycle iniiated when the carriage is in the last columnar yosituin the end of .its normal tabulating -overnent, except when such a machine cycle is iitiated hy depression and continued manual -ol "ng down oi' the lower motor har, the caris returned across 'the machine to the right iewed lroro the front or leftward in `liig. 19, ter operation ci the printing mechanism, by a motor-driven carriage return mechanism which, to that disclosed in the Patent No. l,580,534l.

is disclosed in detail in the Rinsche Patent No. T-dg a rack bar i3@ (Figs. l, i3 and 19) on the carriage meshes with gear teeth on the pci'iphery or" the driven member itl (Figs. l and i3) of a clutch located in housing and powered through a drive means in the housing from the drive motor 25 of the machine. Ii lever (Figs. i3 and le), pivot-.ally mounted at on a stationary plate lil, ycauses 'engagement ci the clutch when it is rocked clockwise in Fig. (counterclockwise in Fig. lll) and .disengages the clutch when said lever is returned to its normal position of Fig. i3. The clutch control lever after being rnoved to either position, is yieldingly held in such position by a stud ltd on pivoted spring-urged detent lever @33d engaging in one or the other of a pair of notches in said clutch control lever it.

The rear arm ci the lever M3 (lz'lig. 1) has two shoulders llll and lill between which is a forwardly' extending slot wider than a stud lill. carried hy a lever l (Figs. 1 and 6) pivoted on the stud and urged clockwise by a spring Mrt so that it tends to follow the lower arm or" the three-armed lever iid when the latter is rocked clockwise during the, forward stroke of each machine cycle. -`When the lower motor bar L is in normal elevated position, the lower shoulder ilil is in the path of the stud M112 and when said motor bar is manually held fully depressed the upper shoulder lill is in the @ath oi the stud lill? and the lever M3 is thus rendered ineective. But when manual pressure is withdrawn from the lower motor bar L immediately after it is depressed, the bell crank and stud il permit the lower motor bar to return upward part ci the distance to normal and suiciently to align the slot between the shoulders Mil and Mi with the stud M2 so that the latter can enter the slot and the lever |43 portion of the l lil ` pawl led under a shoulder can follow the three-armed lever 55 and permit a stud i635 in the lever M3 to act on the cam end of an arm tot of a lever IM and rock 'the latter counterclcckwise about the stud Mtl on which it is pivoted. The lower brancher the lever lill has astud and slot connection with an arm M9 secured on a shaft ll) journaled beneath the rear portion of the machine frame and also having secured thereon an arm l5l carrying a stud l positioned above a projection on a pawl 653 (Figs. ll and l2) pivoted on a link i555 and held in contact with the stud i152 by a spring itil, A stud projecting into a vertical slot in the link liifl is carried in the rear end of a lever lill pivoted on a iixed stud i553 (Fig. ll) .and urged clockwise (Fig. ll) by a spring liitl. The forward earn end or the lever lei is positioned in the path ci a stud lull on a crank ann secured on 'the shaft fl@ so that the stud ld is moved downward in each machine cycle near the end of the revolution ci the llt.

The pawl is normally out or engagement with the stud il but when, during a machine cycle initiated icy depression of the lower motor bar L and immediate withdrawal of manual pressure from said motor bar, the stud M2 enters the slot in the lever ll, the consequent rocking of levers lill and arms Mill and lill and depression of stud rocks the pawl 'to engage its hooked end under the .stud itt so that when the latter moves down during the machine cycle, the

link itil is also pulled down.

The upper end of the link iliil (Fig. i3) is connected to a slide Hi guided for vertical movement on a stud itt secured in the plate ll. A pawl lli?? pivoted on a stud l dfl secured in the slide lill is urged counterclockwise by a spring 55 to engagea lateral lug on its upper end against the edge of a latch pivoted on a stud lll secured in the plate itl. When the link llil and thus the slide l Si and pawl l lili are pulled down, the spring ltd positions the lateral lug on the end of the lill? on the latch lot. When the stud l@ passes the cam end of lever itl and the stud itil and link l5@ are raised to normal by the springs ld and l t, the latch lli is rocked to disengage a shoulder it@ thereon from a 1ateral lug on a lever il@ pivoted on the stud dell, whereupon the lever is rocked clockwise by a spring lll pulling upwardly on a lateral lug on a link 5?/2 pivoted on a stud llt which is secured in the lever il@ and passes through a slot in a lever il@ pivoted on a stud llt secured in the plate lill. Thereby the link llt, which has a notchreceiving a stud llt on the lever i3d is elevated and rocks the lever i3 to engage the carriage return clutch, Also, a nger lll on the lever llil engages the lateral lugr on the upper end oi the pawl itil and disengages it from the shoulder itil to permit a later return of the parts to normal. A stud llt* on the lever l'lll is raised into the path of a control roll lll so adjustably located on the paper carriage that, when the latter has been returned a little beyond a selected columnar position (column .2 for the example of work to be described later), the roll il@ will depress the stud H8 and restore the lever il@ and link il? to their normal depressed position where a spring lis@ causes the latch itu to relatch the lever il@ and the link H2, the lever H35 being rocked to clutch-releasing position by said link H2. Thereupon, the carriage moves a short distance in the tabulating direction until arrested by engagement of the abutment l lll with the co1- umn stop I i3 for the selected columnar position.

' i A spring |9| (Fig. 14) yleldingly holds a stud |92 on the lever |35 in a slot in the end of a link |93 plvotally connected.with one arm of a bell crank |99 controlling a switch |35 connected in parallel to the switch controlled by the link 39 w insure that the power circuit of the motor will be closed whenever the carriage return clutch is in engaged condition. f

The stud |92 also overlies the end of a lever |99 pivoted ony a stud |9| secured in a slide |92 slidably mounted on studs 91 and |93 secured in the plate |31. The lever is urged clockwise in Fig. 14 by a spring |99 but, with the slide |92 in its normal position of Fig. 13, a stud |95 secured in the plate |31 and engaged by an edge of the lever |99, holds the latter, as in Fig. 13, with its end depressed suiliciently to permit the lever |35 to oc- -cupy the clutch-releasing position.

A slide |99 is slidably mounted on studs |91 carried by the slide |92 and is urged to the right in Fig. 13, relative to the slide |92, by a spring |99 connected between one of the studs |91 and'a, stud |99 secured 'in the slide |99. The slide |95 also has an upturned ear 209 having a slot penetrated by a stud 29| secured in one arm of a bell crank 292 pivoted on a stud 293 carried in a downturned lug of the slide |92. When the carriage tabulas into its last columnar position, a control member 299 adjustably secured on the rack |39 engages the slide |95 and moves it slightly (leftward in Fig. 13) on and relative to the slide |92 against the yielding tension of the spring |99 thereby rocking the bell crank 292 to place a lug 295 thereon in the path of an arm of a bell crank 299 pivoted on the stud |15. At the saine time, a stud 291 on the bell crank 292 cams the bell crank a short distance counterclockwise (Fig. 13) and lowers a link 209 plvotally connected to the second arm of the bell crank 209 and urged upwardly by a spring 209. A pawl 2|9 (Figs. 11 and 12) pivoted on the lower portion of the link 299 is' urged counterclockwise in Fig. l1 by a spring 2I| and has a forward projection underlying a stud 2l2 which is carried by the lever |5l and normally holds the hooked lower portion of the pawl 2|9 rearwardly of the path of the stud |55. However, the depression of vthe link 205 by the action of the control member 209 on the carriage as the latter moves in the tabulating direction into its final columnar position is sufficient to permit the pawl 2|0 to'be rocked by its spring 2|| to place its hooked lower end under the stud |59 so that when the stud |59 is lowered ina machine cycle, the link 209 is pulled further downward and through the bell crank 209, moves the slide |92 carrying the lever |99 leftward in Fig. 13 and to the right in Fig. 14 whereby a notenv z l a in the edge of the lever |99 is brought into alignment with the stud |95 and permits the spring |99 to rock said liever |90 and the lever |35 to engage the carriage return clutch. At the same time, a finger on the slide |92 engages aV stud 2|9 on the link |12 and disengages the latter from the stud |19 on the lever |35.

When the carriage has been returned a little past its rst columnar position, a lug 2 I5 (Fig. 19) on a control member 2|6 adjustably mounted on the rack |39 engages a lug 2|1 on the lever |90, rocking the latter back to normal position and then shifting the slide |92 back to normal position as a cam linger 2|9 on the control member 2|9 engages the stud |19 on lever |35 and returns the latter to clutch-releasing position, whereby the switch |95 is also reopened. The carriage is then permitted to move slightly in the tabulating direction until stopped by engagement of a column stop ||3 against the abutment ||9 for the column 1 position of the carriage.

To facilitate the insertion and removal of the record material or work sheets about the platen P, the illustrated machine is provided with an automatically .controlled power-operated front feed mechanism like that disclosed in my prior Patents Nos. 2,202,595 and 2,202,596. Portions of this mechanism are shown in Figs. 1 and 18.

The illustrated machine has both manual and automatic controls for enabling it to perform various kinds of operations. The positioning of the crossfooter for engagement of the add pinions 99 or the subtract pinions |99 for engagement with the actuators is controlled manually through the subtract lever S (Fig. 3) and automatically by the carriage, as disclosed in the Pasinski Patents Nos. 1,778,506 and 1,911,768. The subtract lever S, pivoted on a ilxedstud 220, has a rearward arm 22| connected to a. link 222 having a stud 223 within a slot in a pitman 229. The rear portion of the pitman 229 has an upper branch having a shoulder 225 adapted to cooperate with a stud 229 and also has a lower branch having a shoulder 221 adapted to cooperate with a stud 229. The studs 226 and 229 are carried by a plate 229 secured upon the familiar 999 shaft which is rocked counterclockwise (Fig. 3) during the forward stroke and is returned clockwise during the return stroke of each cycle by the usual connections with the shaft 99. Normally, the parts occupy the (adding and positive total-taking) position of Fig. 3. When, however, the lever S is moved to the (subtracting and negative total-taking) position indicated in dot-and-dash line in Fig. 3. the link 222 and thus the rear end of the pitman 229 are raised to Place the shoulder 225 in the path of the stud 229 so that, during the forward stroke of the cycle, the-pitman will be drawn rearward. The forward end of the pitman 229 is plvotally connected to a cam lever 239 which is pivoted on the stud 220 and tumbles the crossfooter frame |9| in the well-known manner. When the pitman 229 is drawn rearward, the lever 230 is rocked clockwise from its Fig. 3 position to tumble the frame |9| to the position where the subtract pinions |00 are presented for engagement with the actuators 99. When the lever S returns to the position, the rear end of the pitman 229 is lowered again to place the shoulder 221 in the path of the stud 229 so that, during the forward stroke of the following cycle, the pitman 229 will be moved forward to rock the cam lever 239 counterclockwise to its Fig. 3 position to tumble the frame |0| to the position to place the add pinions 99 in position for engagement with the actuators 99.

The subtract lever S also is plvotally connected to a link 23| having, near its rear end, a notch receiving a stud 232 on a lever 233 plvotally mounted on a fixed stud 239. A spring 235 connected to the lever 233 urges the parts to the position of Fig. 3. A bell crank 239 plvotally supported on a rear arm of the lever 233 can be rocked against the tension of a spring 231 clockwise from its Fig. 3 position relative to the lever 233 but cannot be rockedrcountercloekwise beyond its Fig. 3 position relative to the lever 233. 'Ihe rear arm of the bell crank 239 engages in the forked end of one arm 239 of a yoke plvotally supported on a xed stud 239 and having a second arm 299 positioned to be acted upon by rolls I29| adjustably mounted on the carriage C. When a carriage roll 29| moves over the arm 299 it de-` presses the latter and raises the arm 238 and bell crank 236. The lever 233, if not impeded, is thereby rocked clockwise (Fig. 3), the spring 231 being capable of overcoming the spring 235, and moves the link 23| and lever S forward to the position so that, during the forward stroke oi the neXt cycle, the crossfooter tumbling frame im will be tumbled to the position. The spring 231 and bell crank 23S permit the lever S to be manually held in the -lposition even when there is a carriage roll 2M holding the arm 24|! down.

The engagement and disengagement of the crossfooter pinions S9 or lll and the actuators l t are effected by mechanism which is like that shown in the Rinsche PatentI No. 1,l72,1i34 and the Pasinski Patents Nos. 1,778,506 and illf and is normally conditioned for amount entering operations. The crossfooter main frame lll@ pivoted at H34 has a rearwardly extending link 2&2 pivoted on its left-hand side member` below the pivotal support itil. The link 242 has a shoulder adapted to cooperate with a stud on the familiar arm dill secured on the itil@ shaft whereby the frame H03 will loe rocked to engage the crossfooter pinions 39 or lill) with the actuators 98 at the end of each cycle of operation of the machine if they should be out of engagement with the actuators at that time. Above and below the pivotal support itil, the left side member of the crossfooter main fram@ llll has two studs Edil and 245 adapted to cooperate with notched and shouldered upper and lower branches on the lower forward end of a link 2&5 pivotally connected at its upper rear end to the middle arm of the familiar three-armed roclking lever the forward and rearward arms ci which carry studs and 248, respectively, which are adapted to cooperate with the usual passwlcy pawl carried. by the arm dit. At the beginning of each cycle of operation, the par/l 332i engages the stud ll and rocks the threewarined lever 9i 3 counterclcckwise in Fig. 3, thus moving the link Bild forward. y

In amount entering operations, the forward end of the link 246 is held upward in the position ci Fig. 3 by a spring 2d@ with the stud 23d engaged in the notch in the upper forward branch or said link MS. Thus, when the link tilt is moved forward at the beginning of the cycle, the cross iooter main frame lill? is rocked to disengage the crossfooter pinions from the actuators. Near the end of lthe forward stroke oi the cycle, the passby pawl 82| engages the stud 2&3 but yields without rocking the lever tit. During the fdrst part oi the return stroke, however, the pawl @2i acts on the stud 248 to rock the lever Sit clockwise (Fig. 3) back to its normal position, thus drawing the link M6 rearward and rocking the crossfooter frame |03 to engage the crossfooter pinions 99 or ||J|l with the actuators Bil, after which the latter are returned upward to normal from the differential positions corresponding to the depressed amount keys, whereby the amount which was set up on the keys is added or subtracted depending upon whether the pinions 99 or lil are engaged with the actuators. At the end of the forward stroke, the pawl 82l engages the stud 2li? but yields without rocking the lever 9l3.

The crossiooter may be non-added The pawl 82| acting on the stud Ml disengages the cro'ssiooter pinions from the actuators at the beginning of the non-add cycle of the machine just as in an adding or a subtracting amount entering operation. However, when the pavvl 82| approaches the stud 248 near the end of the forto its ward stroke of a. non-add cycle, engagement of the paw] 82| with the stud 248 is prevented by a pawl 250 pivoted at 25l and normally held clockwise from its Fig. 3 position so that it normally does not interfere with the action of the pawl 82|. The pawl 25@ has a stud 252 engaged in the slotted end of a lever 253which is connected through a link 255 with an arm 255 pivoted at 236 and held by a spring 256 in engagement with a lateral lug on a. lever 25'? also pivotally supported at 23d. The rear end of the lever 2li? engages in the slotted end oi7 one arm of a yoke 255@ rockably supported on the stud 23e and having a second arm adapted to be acted upon by rolls 265i adjustably mounted on the carriage C. When a carriage roll, 2M holds down the arm 2t@ as shown in 3, the levers 25W and arm i255 are held in the clockwise position shown in Fig. 3, thus holding the link 25d and arm down and the pawl 25@ clockwise in. the position shown in Fig. 3 to prevent the pawl @2l from acting on the stud Edil. Thus, when the parts are positioned as shown in Fig. 3 by a roll on the carriage, the crossiooter pinions will not be engaged with the actuators @d at 'the beginning of the return stroke oi the cycle.'

The crossfooter main frame ills also has pivotally connected thereto the forward end or" a link 252, the rearward end ofi which is normally held elevated by a 263 and has a shoulder adapted to be engaged by a stud Zilli on the arm ill@ at the end or the forward stroke ci? 'the cycle. However, the arrn has a dinger extending .torward over a lateral lug on. the forward end of the link so that, when the arm is moved Fig. 3 position by a carriage roll 259, the forward shoulder of the link is held out of the path oi the stud 236. Illlhe parts just described rnay also be moved to the non-add position illustrated in 3 manually by the usual Non-add key (not shown).

For total-taking operations, the connection between the link ad@ and the crossfooter main frame lila is altered. The bell crank El@ of the total key T carries a stud 2li which extends into a slot in a link dit, the lower end of which has a slot embracing a stud Zit on the toi-ward end oi the link and is also connected to the upper end oi the spring Upon depression of the total key T, the link @l2 is lowered, thereby lowering the forward end of the link tilt to disengage it from stud 25d and to permit engagement of the notch in the lower forward branch of said link iii-lt over the .stud 2415. Accordingly, when the link llll is moved forward at the beginning of the forward stroke ol? the cycle, the crossiooter main trarne i will be rocked to engage the pinions @il or tilt with the actuator racks if they are not already so engaged. At the beginning of the return stroke, the rearward movement of the link 2da disengages the crossfooter pinions from the actuators and at 'the end of the return stroke the stud 2te engages the shoulder on 'the link 2&2 and re-engages the crossfooter pinions with the actuators.

In subtotal-taking operations, the crossfootcr pinions are not disengaged from the actuator racks at the beginning^ of the return stroke of the cycle. The bell crank 22a of the subtotal key ST is connected to a link 256 having a shoulder 271 adapted to engage a stud 218 on the bell crank 2id of the total key T so that depression of the subtotal key ST also rocks the total key bell crank 2li) and lowers the link 212 and the forward end of the link 246 as for total taking.

pinions from the actuators at The link 216 c'arries a stud 219 which, upon depression of the subtotal wardly extending finger of the pawl 250 and rocks said pawl clockwise from its normal ineflective position to the position of Fig. 3, where said pawl prevents the pawl 82| from acting on stud 248 with the result that the link 246 is not moved rearward to disengage the crossfooter the beginning of the return stroke of the cycle.

The mechanism may also be automatically conditioned for the taking of totals and subtotals from the crossfooter under the control of the carriage, as will be described later.

The illustrated machine is provided with an interlock means like that disclosed in the Pasinski Patent No. 1,778,506, which prevents depression of a total key whenever the position of the crossfooter tumbling frame i| and the position of the subtract lever S do not both correspond to the sign of the total contained in. the crossfooter.l

Provided that the positions of the crossfooter tumbling frame and the subtract lever coincide and both correspond to the sign of the total contained in the crossfooter, totals and subtotals, both positive and negative,` may be taken from said crossfooter without a spacing cycle prior to the total-taking cycle, the illustrated machine being provided for this purpose. with mechanism like that disclosed in ,my Patent No. 1,844,070.

The total key bell crank 210 is connected through, a link 290 to an arm 29i secured on a shaft 292 which extends through the machine. Near the right side of the machine, the shaft 292 has secured thereon an arm 293 (Fig. 6) connected to a link 294, the rear end of which is urged upward by a spring 295. The rear end of said link 294 has a shoulder 296 normally in front of a lateral lug on one arm of a latch lever 291 which is urged counterclockwise by a spring 298 and has a second arm having a shoulder 299 normally engaged behind a lateral lug on. a lever 300 pivotally mounted at 30| and connected with the rear end of alink 302. As in my said prior Patent 1,844,070, rocking of the total key bell crank 210 a short distance toward totaltaking position causes the shaft 292 to be rocked clockwise in Fig. 6 and the link 294 to move rearward and disengage the latch shoulder 299 from the lever 300. A spring 303 connected to the link 302 thereupon pulls said link rearward and rocks the lever 300 counterclockwise. A stud 304 on the lever 300 engages in a slot in the link 294 so that the rocking of lever 300 by' the spring 303 completes the movement ci the total key bell crank 210 to total-taking position.

The link 302 is connected at its forward end with the lower arm of a member 305 secured on a shaft 30B. As in my said Patent No. 1,844,070, the counterclockwise rocking of said member 305 and shaft 306 by rearward movement of the link 302 results in the crossfooter'being disengaged from the actuators, the restoring to normal of any actuators which are out of their normal 0" positions in consequence of tens transfers eilected during the preceding cycle of operation, and the rocking of a bail 301 (Fig. 3) which releases the transfer pawl latches and permits any transfer pawls moved in tens-transfer operations during the preceding cycle to return to normal. 'I'he link 302 also carries a stud V3H) (Fig. 6) which, when the link moves rearward, engages one arm of a bell crank 3l I, the other arm of which is connected through a stud and slot connection key ST, engages an upl the control link 312 to a spring 3|3 which, in turn, is secured to a connecting piece 314 (Fig. l) The connecting piece 314 has-an aperturcd lug through vwhich 34 passes and which is clamped between two nuts threaded on the lower end of the link 34 below the clutch arm 31 so that, when said connecting piece 3I4 is drawn upward, it not only rocks the arm 31 to cause engagement of the clutch and closing of the motor switch, but it also lifts the clutch control link 34 and thereby causes depression of the main motor bar M.

As the lever 300 is rocked counterclockwise (Fig. 6) by the spring 303, the stud 304 not only pulls the link 294 rearward but also depresses its rearward end and lowers the shoulder 296 below the lateral lugon the latch member 291 so as to permit the shoulder 299 on said latch `member to re-engage behind the lateral lug on the lever 300 when it is restored to normal during the ensuing cycle. The restoring of the lever 300 during said cycle is effected by a stud 3|5 on the arm 46 engaging the lower arm of a lever 3I6 pivoted at 3|1 and having in its upper arm a slot in which engages a stud 3I8 on said lever 300.

Thus, the rocking of the total key bell crank 210 while it is free, i. e., while the position of the subtract lever S and the position of the crossfooter tumbling frame 51 correspond to the sign t of the total in the crossfooter, not only effects the operations necessary to condition the machine for a total-taking or subtotal-taking cycle but also initiates the machine cycle for taking the total or subtotal.

If the position of the crossfooter tumbling frame and the position of the subtract lever S do not coincide with each other as well as correspond to the sign of the total in the crossfooter when the paper carriage occupies a columnar position where a total or a subtotal should be taken from the crossfooter, it will sometimes be necessary to give the machine a spacing cycle of operation for tumbling the crossfooter to the position corresponding to the sign of the total before the total key or subtotal key can be depressed. In such a case, the carriage should remain in the same columnar position until the total or subtotal is taken. With the illustrated machine set up for the example of work shown in Fig.' 20 and presently to be described, it will sometimes occur that a, `negative total vis contained in the crossfooter when the carriage arrives in the column 5 position where a crossfooter subtotal is to be taken and printed, whereas the subtract lever S and the crossfooter would normally be in the position at that time so the operator may be required to move the lever S to the position and give the machine a spacing cycle to tumble the crossfooter to the position. The machine is provided with a means like that illustrated in Figs. l, 10 and 11 of my prior Patent No. 2,202,596, which automatically disables the tabulating mechanism when the carriage reaches a predetermined columnar position, the column 5 position for the example of work shown in Fig. 20. and keeps it disableduntil the total key or subtotal key is depressed so that the carriage will not tabulate tothe next columnar position until the total or subtotal is taken. For the example of work illustrated in Fig. 20, the column stop H3 for the column 5 position of the carriage is slotted in the manner of the column stop |22' of my said Patent No. 2,202,596.

the total still in the crossfooter.

Example of work Fig. 20 illustrates a statement form such as prepared in a bank in connection with a customers checking account. Columns 6 and 7 of the illustrated form are on a portion which can be detached from the remainder of the form along the line of perforations between columns 5 and 6.

Columns l, 2 and'3 are the usual old-balance- -pickup and checks columns. Column 4 is the deposit and column 5 the balance column. Column 6 of the detachable portion is also a balance column and column 7 is the analysis column. Of course, any desired kind of analysis data could be entered in the analysis column 7, but, for the sake of an illustration, the figures which have' been entered in column 7 of Fig. 20 represent the amounts of deposited checks which have been entered to the customers credit but not immediately collected. :l

In making the entries in line I of the statement form of Fig. 20, the old balance of 100.00 is set up on the keyboard of the machine with the paper carriage in the column. 1 position. The machine is set into operation by depression of the regular motor bar M, whereupon the old balance of 100.00 is added in the crossfooter. After the printing mechanism. has operated to print 100.00, the carriage tabulates to the column 2 position where it automatically sets the crossfooter controls for subtraction. The operator sets up 25.00, the amount of a check, on the keyboard and again depresses the regular motor bar M, whereupon the machine operates to print the amount 25.00 in column 2 and subtracts this amount from the crossfooter. After the printing operation in co1- umn 2, the carriage tabulates to the column 3 position where the amount of another check 30.00, is entered and printed in column 3 and subtracted from the crossfooter in a cycle of operation also initiated by depression of the regular motor bar. The carriage then tabulat'es to the column 4 position where it automatically conditions the crossfooter controls for addition. The operator then sets up 75.00. the total of a number of deposit items, and depresses the regular motor bar M to give the machine a cycle of operation during which the amount 75.00 is added in the crossfooter and. printed in column 4, whereupon the carriage tabulates to the column 5 position and the machine is automatically given. a cycle of operation during which a subtotal is taken from the crcssfooter and printed in column 5, leaving The carriage then tabulates to the column 6 position, whereupon the machine is given another automaticv cycle of operation during which the total is taken from the crossfooter, leaving the latter clear, and

printed in column 6. Then the carriage tabulates to the column '7 position where the operator enters the amount 50.00 on the keyboard and depresses the regular motor bar to give the machine a cycle of operation during which the amount 50.00 is printed in column 7 and the carriage return mechanism is set into operation to return the carriage to the column Lpostion.

In making the next line of entries, line II on the form of Fig. 20, the operator reads the balance, 120.00, fromv column 5 or 6 in line I, sets this up on the keyboard and depresses the regular motor bar M to give the machine a cycle of operation for adding this amount in the crossfooter and printing it in column 1, after which the carriage tabulates to the column 2 position. Here the operator sets up 60.00, the amount of a check, on the keyboard and, noting that there is no further check to be posted, the operator deprees the upper motor bar U. Also noting that therey is a deposit to be entered in column 4, the operator depresses said motor bar U and manually holds it fully depressed. In the ensuing operation of the machine, 'the amount of the check is subtracted from the crossfooter and printed in column 2, after which, because of the manual holding down of the upper motor bar, the carriage skip tabulates to column 4 and the machine comes to rest. Here the operator sets up the amount of 20.00 on the keyboard and, noting that this deposit does not require the entry of any analysis gures in column 7, the operator again depresses the upper motor bar U which causes a machine cycle in which the amount of the deposit is added in the crossfooter and printed in column 4, after which the carriage tabulates to column 5. When the carriage reaches the column 5 position, the machine is automatically cycled to take and print the crossfooter subtotal, after which the carriage tabulates to column 6, where the machine is automatically cycled to take the total from the crossfooter and print it.

As a result of the depression of the special motor bar for the column 4 entry in line II, the carriage return mechanism is set into operation after the printing of the total in column 6 and the carriage is returned to the column 1 position Without entering the column 7 position. This saves thetime which would ordinarily be required by tabulation of the carriage into the column 7 position and by manual depression of a motor bar by the operator after the carriage reaches the colunm 7 position.

It is also noted that the depression o the upper motor bar U which causes the carriage to be returned from the column 6 position instead of tabulating into the column 7 position is eiected Ibythe operator at the time of initiating the machine cycle for the entry in column d. The presence or absence of analysis data to be entered inc column 7 is determined by the nature of the item entry in column 4 and at the time of making the column 4 entry .the operator has in mind the fact that analysis data are lor are not to be en-n tered in column 7. In line I, the operator, at the time of setting up the amount of the deposit, '75.00, on the keyboard for the entry in column d, noted that some of the items included in the deposit required analysis data to be entered in column 7 and, therefore, depressed the regular motor bar IVI for the entry in column 4. The

operator could utilize the time during which the At the time of setting up me amount or 20.00

' on the keyboard for entry in column 4 in line II,

the operator, noting that no analysis data were to be entered in column 7 in line lLdepressed the upper motor bar- U and could then immo-1 `1 O diately dismiss from mind any question regarding column 7. The operator did not have to wait until after the total was printed in column 6 to do anything further to cause the carriage return to 4column 1. Instead, the operator could utilize 5 the time during which the machine was performing the automatic cycles for the printing of the balances in columns 5 and 6 in making ready for the next posting operation to be performed.

In line III, the old balance of 80.00 is entered l0 in the pickup column l and 5.00, the amount of a check, is entered in column 2, both machine cycles being initiated by depressions of the regular motor bar M in the lusual way. In entering 10.00, the amount of a second check, in column 3, the operator, noting that there is no deposit to be entered in column 4 in line III, depresses the upper motor bar U and immediately withdraws manual pressure from it. After the printing of the amount of 10.00 in column 3, the carriage tabulates to the column 4 position and the ma,- chine is immediately automatically given a cycle of operation during which the crossfooter is tumbled to adding position so that, when the lcarriage tabulates to the column 5 position, the add pin- 25 ions of the crossfooter are positioned for engagement with the actuators for the automatic subtotal-taking operation during which the balance is printed in column 5. After the printing of the balance in column 5, the carriage tabulates to the column 6 position 4where the total is taken from the crossfooter and printed, after which the carriage is returned directly to the column 1 position without tabulating into the column 'i position. In the making of this third line of entries, the upper motor bar U was depressed while the carriage was in the column 3 position and remained depressed until near the end of the automatic cycle while the paper carriage was in the column 4 position. The upper motor bar 40' U, being in depressed position during the c'ycle with the carriage in the column 4 position, caused the carriage return mechanism to be conditioned to return the carriage from the column 6 position to the column 1 position. This was correct 45 because, there being no deposit to be entered in column 4, there would, in the example of work being described for the purpose of illustration, be no analysis data to be entered in column 7.

It should be noted at this point that the carf riage is not necessarily returned to the column 1 position from the column 6 position at the end of a line of entries in which no entry is made iii column 4. Suppose, for the sake of illustration, that the analysis data to be entered in column '1 55 might sometimes be based upon entries made in some other column besides column 4. For example, suppose that, in accordance with the system being used in a particular business, the nature,l of the debit item in column 2 or column 3 of linez .o III was such as to necessitate the entry of data in column '1 even though there was no item to be entered in column 4. Inthat case, the operator, in initiating a machine cycle for the entry in column 3, would depress 'the upper motor bar g5 U and maintain manual pressure on the motor bar until the machine comes to rest with the carriage in column 4. Then the machine would not perform an automatic cycle when the car-y` riage reaches the column 4 position but the oper- 10 ator could then release the upper motor bar U and immediately depress the regular motor bar* M to cause the needed cycle of operation in eolumn'4 for tumbling the crossfooter to adding position, after which the balance would be printed 'Il in columns 5 and 6 during automatic cycles of the machine and the paper carriage would tabulate into the column 'i position after the printing of the total in column 6.

In line IV on the work sheet shown in Fig. 20, therevare no checks or debit items to be entered 'in columns 2 and 3. Noting this at the time of setting up the amount of the old balance, 65.00, on the keyboard for the column 1 entry, the operator depresses the upper motor Abar U and continues to hold it fully depressed. After the printing of the amount of 65.00 in column 1, the carriage skip tabulates to the column 4 position. No automatic cycle is performed by the machine at this time because the upper motor bar is held fully depressed until the carriage reaches the column 4 position. The operator then releases the upper motor bar, sets up theamount of the deposit, 50.00, on the lkeyboard, and depresses the regular motor barv M to initiate the deposit ,entering cycle of the `machinein view of the fact that the nature of some of the deposit items included in the 50.00 amount is such as to require the entry of analysis data in column '7.

The amounts entered in the several columns on the work form in Fig. 20 may be added into different ones of the multiple registers |05 or the multiple registers may be non-added in selected columns. Fig. 20 indicates that a roll 26|x is placed on the carriage to non-add the crossfooter when the carriage is in the column 7 position.

The foregoing description of one example of work is not to be considered as limiting the scope of the invention in any way. One example of work has been described merely to facilitate an understanding of the following detailed description of the mechanisms involved, and it will become clear from the following description of the mechanismsl that the invention is equally well adapted for use in the performance of other varieties of work, many of which may involve different sequences of loperations of the manual and automatic controls of the machine.

Carriage skip tabulation The carriage tabulating mechanism which normally causes the carriage to tabulate to the next columnar position during the latter part of each machine cycle has already been briefly described. When there are no entries to be made in certain columns on the work form, as in column 2 in line II and in columns 2 and 3 of line IV of the work form shown in Fig. 20, it is desirable to have the carriage skip past these columns. This result is obtained under control by the upper motor bar U.

The stem 82y of the upper motor bar U is pivotally connected to an arm 325 (Fig. 1) pivoted on the stud |29 to guide said stem 82 in its movement. The stem 82 also carries a stud 3,26 normally positioned above the upper cam end of a lever 321 pivoted on the stud |20 and connected at its lower end to the forward end of a spring 328 which is connected at its rear end to the lever |41 and normally holds a stud I2! in the lever |41 in contact with the rear edge of the lower arm of the lever 321. The stud 229 also projects into a three-cornered cam slot 230 (Fig. 1) inV a lever 33| pivoted on a stud 332 and having two forward projections, the upper of which is normalhr held engaged against the underside of a stud $33 by a spring 334 connected between said stud 333 and the lower forward projection of the lever 33|,
