Means for causing consecutive numbering mechanism to print a consecutive number A printing operation of the consecutive num bering mechanism involves moving the consecutive numbering counter into engagement with the platen on the paper carriage, it being understood, of course, that the ink ribbon 9 intervenes so as to make an impression on the paper. This movement of the counter is obtained by rocking the lever 22 on its pivot 23 to move the viewed in Fig. 3 by a spring 32 against a stud on the bell crank lever arm 2d. The lower end of the arm 3!! is positioned in the path of a shaft 36 (Fig. 2) carried by the crank arm it! fixed to the shaft 62. During each operation of the machine the shaft 34% is moved rearwardly, or clockwise as viewed in Fig. 2, into engagement with the lower end of the arm 39. This moves the arm 3!! counterclockwise as viewed in Fig. 2, or clockwise as viewed in Fig. 3. This movement of arm 3! tensions a spring 35 connected between the arm 36 and a stud on the bell crank arm iii. If the bell crank 25-26 is held against movement, as will be hereinafter explained, it follows that, during each operation of the machine, the spring '35 will be tensioned and it will exert a force on the bell crank 2526 tending to rock it clockwise as viewed in Fig. 3. The bell crank, in turn, tends to rock the lever 22 counterclockwise. In other words, during each operation of the machine the consecutivenumbering mechanism is urged toward printing position by a means that is tensioned during each operation of the machine.

Automatic advancing means It is necessary to advance the consecutive trio to the axis of the pivot 23 of the lever 22.

When the lever 22 is rocked counterclockwise as viewed in Fig. 3, stud 412 operating in the slot 418 causes the yoke it to be rocked clockwise a predetermined distance.

Pivoted on the yoke it is a second yoke 643 having a series of pawl fingers 45 (Fig. 4) adapted to engage ratchet teeth 35 on their respective counter pinions 2t (Figs. 1 and 4). This second yoke 66 is urged clockwise as viewed in Fig. 4

by a spring 37.

The yoke to carrying the pawl fingers 45 carries a pawl finger for each pinion. The arrangement is such that the pawls for the tens, hundreds and higher order pinions are active only when the pinion of next lower order has moved from its 9 directly to or through its ,0 post tion. In other words, the pawls in orders higher than the units order act only to efiect a tens transfer. Details of construction of this mechanism do not form a part of the present invention and since they are well known they have not been illustrated or described in detail. In referring to the pawl fingers 45 in the following description reference will be made to the units order only.

When the yoke lit is rocked counterclockwise as viewed in Fig. 4, the pawl it for the units order moves over the teeth of its ratchet [it slightly more than one tooth distance so that the pawl engages the next succeeding tooth of the ratchet when its direction is reversed. As the consecutive numbering mechanism returns to normal, the yoke 66 is rocked clockwise as viewed in Fig. 4 and the pawl finger 55 engages the next ratchet tooth and moves the units pinion one step forward, i. e., it advances the consecutive numbering mechanism a unit.

It is to be observed that, during each printing operation of the consecutive numbering mechanism, the advancing means tends to automatically advance the consecutive numbering mechanism a predetermined amount. Means has been provided for disabling this automatic advancing means under predetermined conditions but this will be later described.

Restraining means for insuring that consecutive numbering mechanism will print only during the proper time in the cycle of operation of the machine It is desirable that the consecutive numbering mechanism operate at the proper time in the cycle of operation of the machine and, to insure this, means is provided for controlling the printing operation of the consecutive numbering mechanism.

Referring to Fig. 2, it will be observed that the arm 22 carrying the consecutive numbering counter has a lateral lug 5t. A number of latches cooperate with this lug to. restrain movement of the arm 22 and we will first describe the restraining means which controls the time during the cycle of machine operation that the consecutive numbering mechanism will print.

This restraining means comprises a latch 51! pivoted at 52 and urged clockwise as viewed in Fig. 2 by a spring 53. The latch is thusnormally held in position to obstruct clockwise movement of lug (Fig. 2) on the arm 22. But, at a certain time during the operation of the machine, the latch is released.

Referring to Fig. 4, a link 5 3 is pivoted to the member I26 fixed to shaft H which shaft, it will be recalled, is first rocked clockwise and then returned counterclockwise during each operation of the machine. The link 5:3 is connected at its upper end to a yoke member 55 pivoted at 55. Yoke member 55 has an arm carrying a stud th operating in slot 5'! in a pivoted latch releasing hammer 58 pivoted at 56 and urged clockwise by a spring 59. The releasing hammer 58 is normally restrained against movement by a latch iiii having a hooked end adapted to engage a shoulder ti on the hammer 58, the latch being urged clockwise (Fig. 4) by a spring 62. The printing mechanism includes arms 63 of which one is shown carrying a bail 64 which supports a plurality of latches 65 that operate the printing mech-: anism in a manner well understood in Burroughs machines. The latch is provided with a tall as positioned in the path of the end portion of bail 84 so that, at a. certain time in the counterclockwise movement of the bail (Fig. 4), which is shortly after the printing hammers 8 have been fired, the latch 68 is rocked counterclockwise by bail 84 to release the hammer 58. This permits the hammer 58 to move under the urge of its spring 59, the stud 55 having moved in the slot 51 so as to permit such movement. The hammer 58 has an abutment face or end 8'! (Fig. 5) and, positioned in the path of this abutment, is a stud 68 carried by the latch 5|. Accordingly, when the hammer 58 is fired the latch 5| is released.

To summarize, these parts operate as follows: As the machine is operated during a forward stroke, the bail 84 is rocked counterclockwise (Fig. 4) to cock the hammers 8 of the printing mechanism. These hammers are released near the end of the forward stroke of the machine in a well-known manner. Also, near the end of the forward stroke and slightly after the hammers have been released, the bail 64 engages thev tail of the latch 88 and rocks it counterclockwise. This releases the hammer 58 which is thereupon moved clockwise by its spring 59. The clockwise movement of the hammer 58 causes the abutment face 61 to engage the stud 88 and release the latch 5| so as to free the consecutive numbering mechanism for a printing operation slightly after the regular printing mechanism is operated and at the end of the forward stroke of the machine.

The parts are restored during the return stroke of the machine at which time the stud 55 engages the end of the slot 51 and returns the hammer 58 counterclockwise as viewed in Fig. 4. This releases the latch 5| for return to normal under the urge of its spring 53. The latch 5| does not, of course, return to latching position until the arm 22 has returned to normal and the arm 22 does not return to normal until the shaft 34 (Fig. 2) has returned and released the member 8|. This enables spring 32 to return the bell crank 25-46 to normal and moves the consecutive numbering mechanism out of printing position. As the lever 22 moves back to normal its lug 58 passes over the shoulder of the latch 5| and allows the latter to return to normal position under the influence of its spring 53.

From the above it will be clear that a restraining means has been provided for the consecutive numbering mechanism which controls the latter so that it will print only at the desired time during a cycle of machine operation, which time is slightly after the operation of the regular printing mechanism and near the end of the forward stroke of the machine.

Carriage control of consecutive numbering printing Provision has been made for controlling the consecutive numbering mechanism automatically so that consecutive numbers can be printed in any predetermined columnar position of the carnage.

Referring to Fig. 2, the paper carriage is provided with one or more cam plates or tappets 18 adapted to engage, in predetermined columnar positions of the carriage, a roller carried by one arm 12 of a yoke 13 pivoted on the back panel of the machine. The other arm 14 of this yoke is connected by a link 15 to an arm I8 fixed on a rock shaft I1. The rock. shaft has a latch 18 fixed to it and this latch cooperates with tht lateral lug 58 on the arm 22 carrying the consecutive numbering wheels 28. This latch restrains the consecutive numbering mechanism against printing and must be released in order that a printing operation may take place. Such release is effected by the engagement of the cam plate 18 with the roller II which rocks the shaft 11 so as to move the latch 18 counterclockwise. For convenience in description, the restraining means including the latch 18 will be referred to as the second restraining means.

Provision is made for automatically disabling the advancing means for the consecutive numbering mechanism when the carriage releases the consecutive numbering mechanism for printing. Referring again to Fig. 2, it will be observed that the latch 18 has an upwardly extending arm 88 positioned over a stud 8| carried by a slide plate 82 urged upwardly by a spring 83. This slide plate carries a stud on its upper end which is positioned over a. tail 85 (Fig. 4) on the pawl finger 45. When the slide82 is in its upper position, shown in Fig. 1, the pawl finger 45 is free to engage its ratchet 48 and the automatic advanc ing means is in operative or enabled condition. But, when the slide 82 is moved downwardly to the position of Fig. 4, the stud 84 engages the tail 85 and holds the pawl finger 45 out of the path of its ratchet wheel so that, even though the yokes 48 and 44' are rocked, the wheels 28 will not be advanced.

From this it will be seen that, when the shaft 11 is rocked by carriage tappet 18 to release the latch 18, the tail 88 will engage the stud 8| and move the slide 82. downwardly so as to automatically disable the advancing means for the consecutive numbering mechanism.

The consecutive numbering mechanism is controlled by a third latching or restraining device which includes a latch 88 adapted to engage the lug 58 of the arm 22. This latch is a part of an irregular shaped member 9| pivoted at 92 and urged counterclockwise as viewed in Fig. 2 by a spring 93. This irregular shaped member has an upwardly extending cam arm 94 positioned in the path of the stud 8|, the parts being proportioned so that when the stud 8| is moved downwardly as heretofore explained, it will engage the cam edge of the arm 94 and rock the latch 98 out of the path of the lug 58.

From the description thus far given, it will be clear that, in a predetermined columnar position of the carriage, both of the latches I8 and 98 will be released and the automatic advancing means will be automatically disabled. When the latches 18 and 98 are released, the lug 58 can move a slight distance so as to move over these latches to prevent them from returning but it cannot immediately move far enough to allow the consecutive numbering mechanism to move to printing position because of the latch 5|. But, during the operation of the machine, the latch 5| is released at the proper time, as heretofore explained, and thereupon the consecutive numbering mechanism operates to print a consecutive number.

When the paper carriage moves away from the column in which the cam plate 78 engages the roller II, the parts return to normal under the influence of their various springs.

It is to be understood that the carriage can be provided with as many of the cam plates 18 as is desired and that, when so provided, the consecutive numbering mechanism will repeat print a consecutive number in any desired number of columnar positions of the carriage and this conecutive number will be the same number because the advancing means is disabled during each of these printing operations.

Total key control of consecutive numbering mechanism Generally speaking, after a total has been taken, it is desirable to advance the consecutive numbering mechanism a predetermined amount and, in order that this may occur, a control has been provided which will now be described.

The carriage is provided with one or more cam plates 800 similar to the cam plates '38 but not quite as large so that when they engage the roller 77!, the yoke 13 will not be rocked as far as when the roller is engaged by a cam plate 70. This movement is far enough to release the latch l8 but the arm 39 that engages the stud 8i does not move the slide 82 down far enough to disable the automatic advancing means. Accordingly, while the latch 18 will be released, the automatic advancing means will not be disabled in the columnar position where one of the cam plates lot is operative.

- In total taking operations, a blank stroke of operation of the machine is usually necessary before the total is taken. This blank stroke occurs before the total key is depressed. In fact, the total key is sometimes locked against depression until the spacing stroke has been given. Inasmuch as the cam l ill? conditions the parts so that the advancing means remains operative, it follows that, if the consecutive numbering mechanism were allowed to print during the spacing stroke, an impression would occur after which the consecutive numbering mechanism would be advanced a unit. Then, during the actual totaling operation, the carriage remaining in its same position, the consecutive numbering mechanism would print a second time but would print a different number. This is undesirable.

But such operation is prevented by the restraining means including the latch 96]. The rocking of the shaft ll bythe cam plate mil is not sufiicient to move arm 88 and stud 8! down far enough to release the latch 90. Accordingly, during the spacing stroke the consecutive numbering mechanism does not print and it is not advanced. Provision is then made for releasing the consecutive numbering mechanism under the control of the total key.

Referring to Fig. 1, it will be observed that the total key T is connected to a bell crank lever ml which, when ,the total key is depressed, is rocked counter-clockwise. This bell crank lever is connected by a link M2 to a crank arm E65 fixed to a shaft R6 3. The shaft N34; has a second crank arm H95 fixed to it. Connected to crank arm 8% is a link H06 provided with an abutment face it? positioned in front of a bell crank latch I08 urged counterclockwise as viewed in Fig. 1 by a spring use. This latch has a lug Hi3 which normally restrains a pivoted arm Hi against movement by a spring H2. The lower end of the member Ml carries a stud H3 engaging in a slot in a releasing latch l is pivoted at H5. The irregular shaped member 9!, of which the latch 90 is a part, has a lateral lug i it in the path of the member lll.

When the total key is depressed, the bell crank latch H08 is rocked clockwise and the member Ml is released, whereupon it is moved counterclockwise by its spring H2. When the member Ml moves counterclockwise, the member 9 M is moved clockwise and the latter engages the lateral lug 2,oos,oar

MG and moves latch 90 clockwise to release the consecutive numbering mechanism.

While the release has been shown as under the control of the total key, it is to be understood that it can be placed under the control of other control keys or manipulative members on the machine.

When a sub-totaling operation takes place, as in column C, Figs. 8 and 9, depression of the total key causes the member lit to engage the lug H6 and move the restraining latch 98 clockwise downwardly out of the path of the lug 50. Pivoted to the restraining latch 90 at HT is an abutment H8 which moves downwardly with the restraining latch 90 and is rocked counterclockwise to a position beneath the lug 50 by its spring H9. When the member N 3 is restored counter-clockwise on the forward stroke of the machine following depression of the total key, the upper end of the abutment H8 engages the underside of the lug 50 and prevents the restraining latch W from restoring to its Fig. 2 position behind the lug 59 until the the lug 50 has been released by the restraining latch i and has moved clockwise with the arm 22 to fire the consecutive numbering wheels. If the lug M8 were not provided, the restraining latch 90 would tend to return to its Fig. 2 position and prevent clockwise movement of the firing arm 22.

From the above it will be clear that, in a second predetermined columnar position of the carriage, the consecutive numbering mechanism can be released for a printing operation without disabling the automatic advancing means. In this second predetermined columnar position, the

printing operation of the consecutive numbering.

mechanism is under the joint control of the carriage and the total key. The consecutive mumbering mechanism is not advanced because the release of the latch 98 by the total key does not move the slide 82 downwardly nor does the small tappet WU move it down sufiiciently to disable the advancing means. I

To put it another way, and taking. into consideration the control by the carriage tappet it as well as tappet H00, in one predetermined columnar position both the second and third restraining devices are released and the advancing means is disabled. In a second predetermined columnar position the second restraining means is released without releasing the third and without disabling the advancing means. In this second predetermined columnar position the third restraining means can be released by a manually manipulatable member which, in this instance, is the total key.

Since any suitable number of cam plates we can be provided, and since the total key can be operated in desired columnar positions of the carriage, it follows that the consecutive numbering mechanism may be advanced in as many columnar positions as is desired.

Example of work The example of work illustrated in Figs. 7, 8 and 9 consists in making certain entries on a check stub, which are duplicated on a journal sheet, and in then writing a check. The various working positions of the paper carriage are represented as A, B, C, D, E and F.

A journal sheet marked Journal remains around the platen during the writing of various checks and the entries on it are simply duplicates of the entries on the check stubs, suitable carbon paper being interposed for this purpose.

With the paper carriage in the position A, the gross amount earned by an employee is entered on the amount keys and the machine operated. In this instance, the gross amount is 50.00 and the number of the check to be written is 4986. In this position of the carriage one of the larger tappets I is operative so that the consecutive numbering mechanism is conditioned for printing and the advancing means for said mechanism is disabled. This means that, when the machine is operated, the number of the check 4986 will be printed, but the consecutive numbering mechanism will not be advanced.

The paper carriage then moves to the next position B where no carriage tappets such as I0 or I00 are employed and the consecutive numbering mechanism is latched against printing. In this column the deductions from the pay of the employee are entered and printed, these being, in the example, $2.25.

The carriage next moves to position 0 where the net pay due the employee is calculated by taking a sub-total from the machine. In this position, the carriage is provided with one of the smaller tappets I00 which partially releases the consecutive numbering mechanism as heretofore described, but does not disable the automatic advancing means for the consecutive numbering mechanism. During the spacing stroke the consecutive numbering mechanism will not be operated, but, during the actual subtotaling operation, the consecutive numbering mechanism will first print the previous consecutive number, that is, 4986 on the forward stroke of the machine, after which the consecutive numbering mechanism will be advanced a unit, that is, to 4987 during the return stroke of the machine. In the description of the invention heretofore given the control of the printing operation of the consecutive numbering mechanism has been described with particular reference to a total key as distinguished from a sub-total key, whereas, in the work above mentioned, a sub-total has been mentioned for column C of the carriage. The control of the consecutive numbering mechanism is the same no matter whether a total or a sub-total is taken, because, in the machine with which the invention has been illustrated, the bell crank lever IOI (Fig. 1) is rocked no matter whether a total or sub-total is taken. In fact, in the particular machine illustrated, the carriage controls the machine sothat a sub-total can be taken by depressing the total key T.

After operations have been completed in column C the paper carriage moves successively to columns D, E and F, to write the check. No carriage tappets 10 or I00 are present in columns D, E and F, and hence the consecutive numbering mechanism does not operate in these columns.

When the carriage returns to column A, the machine is ready for the entry of the gross pay of the next employee which, in this instance, is $40.00. It will be recalled that, in' column A, a carriage tappet I0 is provided which enables the consecutive numbering mechanism to print, but disables the advancing means. It will also be recalled that the consecutive numbering mechanism was automatically advanced to 4987 when the machine operated to print a sub-total in column C. Accordingly, when the machine is operated in column A, the gross amount earned, namely, $40.00 will be printed and the number of the check 4987 will be en tered in the check column. Operations are then continued as heretofore explained.

Second example of work Another form of work is shown in Fig. in which two sets of carriage tappets are employed and in which the third restraining latch 90 and control by the total key are omitted.

When the latch 90 and the total key control are omitted, the consecutive numbering mechanism is released for printing in each of the columns in which carriage tappets are provided because, it will be recalled, both the large tappets I0 and the small tappets I00 release the latch I8. The difference between the use of a large tappet l0 and a small tappet I00 under these conditions is that in one case, namely, with the large tappet 10, the means for advancing the consecutive numbering mechanism is disabled whereas, when the smaller tappet I00 isused, said advancing means is not disabled.

Referring to Fig. 10, the work consists in making entries on stubs of checks and in writing the checks but no calculations are performed with respect to the amount due the receiver of the check.

In column A, one of the large tappets I0 is in position. The salary due the employee, $51.60, is set up on the keyboard and the machine is operated. During the operation $51.60 will be printed as will also the consecutive number 1234. Since the large tappet I0 is in position, the consecutive numbering mechanism will not be advanced but will remain in condition to print 1234 a second time.

When the carriage is moved to column B, a small tappet I00 comes into play and a hammer blocking mechanism of the usual Burroughs type (not shown) blocks the printing of the amount $51.60. The result is that, when the machine is operated, the consecutive number, 1234, will be printed at the end of the forward stroke of the machine in column B. On the return stroke of the machine in this column, the consecutive numbering mechanism will be advanced one unit,- that is, to 1235, because the small tappet I00 did not move the slide 82 down sufliciently to disable the pawl fingers 45.

When the carriage moves to column C, no tappets are active to control the consecutive numbering mechanisms. The amount $51.60 will be repeat printed but the consecutive numbering mechanism will not be operated to print a consecutive number. It remains at 1235.

When the carriage moves to column D, a second large tappet I0 becomes operative. In this column a new salary amount, namely $40.10 is en tered on the keyboard and the machine operated. The result is that $40.10 is printed and the consecutive number 1235 is also printed. But the consecutive numbering mechanism will not be advanced a unit in this column because the large tappet I0 has moved slide 82 down sufficiently to disable pawl fingers 45.

When the carriage moves to column E, one of the small tappets I00 becomes active and the hammer blocking mechanism acts to prevent printing the amount $40.10. During the forward stroke of operation the consecutive number 1235 is printed and, then, during the return stroke, the consecutive numbering mechanism is advanced a unit to 1236. Y

When the carriage moves to column F there is no tappet that is active and, in this column, the amount $40.10 is repeat printed without a printing operation on the numbering mechanism.

The carriage then returns across the machine to start in column A again where operations are repeated as above described for the second set of checks illustrated in Fig. 10. s

From this it is to be observed that any desired number of tappets 10 or I00 can be employed and the same consecutive number can be repeat printed a number of times or the consecutive numbering mechanism can be automatically advanced when required.

It is to be understood that this sample of work is only one of the many that may be performed and it is likewise to be understood that variations may be made in the structure illustrated without departing from the spirit and scope of the invention as defined by the appended claims.
