Abstract: 443,977. Accounting- machines. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Shipley, B. M.; 2021, Catalpa Drive, Sburlino, P. ; 400, Brookside Drive, and Placke, E. H.; 115, Klee Court, all in Dayton, Ohio, U.S.A.). June 12, 1934, No. 17341. Convention date, June 28, 1933. [Class 106 (i)] In a cash register or similar accounting- machine comprising a balance totalizer and lines of positive-item totalizers, negative-item totalizers and auxiliary or grand totalizers, items may be added simultaneously into a positive or a negative totalizer, the balance totalizer and an auxiliary totalizer and, during a single machine operation, an amount may be cleared from the balance totalizer, and transferred to an auxiliary totalizer, or cleared from an auxiliary totalizer and transferred to the appropriate side of the balance totalizer. The invention is described as applied to a Shipley machine having in addition to the usual balance totalizer 141, Fig. 3, and positive and negative transaction totalizer lines 138, 139, a line 140 of six auxiliary or grand totalizers. This additional line of totalizers cooperates with a set of actuating sectors 492 connected to the main actuators by links 493. The required auxiliary totalizer and the appropriate side of the balance totalizer are both selected by the differential latch of the first (or right hand) transaction bank, Fig. 39, this latch being broken either automatically or by the depression of one of the keys 438, 439 in the bank. Engagement is then variously controlled by the first transaction bank latch and the usual total-taking control plate according to the kind of operation involved, the control plate being positioned during the operation by a bank of control keys 210 .. 212. Normal operation. The machine described is for use by a building and loan association and provides for keeping each member's account on a card, Fig. 49, inserted into the machine in the usual manner and impressed and linespaced as described in Specification 442,771. The old balance is first set up on the amount keys and added into the appropriate side of the balance totalizer and the appropriate " Old balance " totalizer in the auxiliary line by depression of one of the keys OC, OD. The various items are then entered into the balance totalizer and selected transaction totalizers using the keys in rows two and three and the motor bar 108. Each item is also entered into a " total credit " or " total debit " totalizer in the auxiliary line, the totalizer being selected automatically according to the sign of the entry. The new balance is taken by depression of the " New Balance " key 210, whereby the balance totalizer is reset and the amount standing therein transferred automatically to the appropriate one of two " New Balance " totalizers in the auxiliary line. Proof-reading operation. At the end of the day, the working of the machine is checked by zeroizing all the totalizers, printing the totals thus obtained on an inserted proof card, Fig. 51, and comparing the sum of the debit entries, old debit balances and new credit balances, with the sum of the credit entries, old credit balances and new debit balances. These should agree. The debit transaction totalizers are first cleared in succession using the No. 3 reset key 211 in combination with the keys in the third transaction bank. The " Total debit," " Old debit balance " and " New credit balance " totalizers are now cleared and the amounts standing therein transferred to the balance totalizer, using the keys 438 in the first transaction bank and the " New balance " key 210. The sum of these totals is taken by depressing the " New balance " key. To prevent this sum being transferred to the appropriate " New balance totalizer, a "Proof" key 654 is depressed in conjunction with the " New balance " key to disable the engaging mechanism for the auxiliary totalizer during this operation. The series of operations is then repeated zeroizing the credit totalizers and taking the sum of the totals standing in the remaining auxiliary totalizers. Keyboards. The keyboard, Fig. 39, is of usual type and comprises banks of amount keys 115, a bank of debit keys 143 controlling the front totalizer line 139, Fig. 3, a bank of credit keys 142 controlling the rear totalizer line 138, a bank of auxiliary or grand totalizer keys 438, 439 associated with the auxiliary and balance totalizers 140, 141 and including a proof key 654 and Account Number key 440, a bank of total-taking keys 210 ... 212 for positioning the usual control plate, and a motor bar 108. Total-taking control plate, positioning ; plunger keys. The usual total-taking control plate 235, Fig. 6, is controlled by a bank of keys 210 ... 212 and an "Add" stop-pawl 389 through a differential mechanism comprising a pair of scissor arms 382, 383 driven by cams on the main shaft 106, the forward ends of the arms co-operating with the pawl 389 or the stem of the depressed key while the rear ends co-operate with a stud 386 on the control plate. The plate is held in adjusted position until the beginning of a succeeding operation by an arm 407 on the usual aligner shaft 166. The "New balance key 210 cooperates indirectly with the scissor arms through a pawl 390. Depression of this key shifts a locking plate 398 downwardly to full extent, thus positioning the horizontal arm of a slot 397 opposite a stud 396 on the pawl to free the latter to the action of its spring 401. Both the " Add " and " New balance " pawls 389, 390 are normally restrained by a cam 392 on the usual shaft 177'that is rocked during total-taking. This shaft is rocked to release the pawls immediately upon the depression of one of the keys 210 ... 212 through mechanism similar to that described in Specification 407,380. Interlocks and release mechanism. Depression of a key, in an inappropriate transaction bank, in conjunction with one of the total-taking keys 210 ... 212, Fig. 39, is prevented by means similar to those described in Specification 407,380. The connection between the total-taking keys and the usual release shaft is also described in that Specification. " Fugitive-one " mechanism. This mechanism is of known type and is actuated by a toothed disc 447, Fig. 24, rigid with the balance totalizer negative wheel 446 of highest denomination. With the negative side of the totalizer engaged with the actuators, the toothed disc is aligned with an arm 449 and, upon the occurrence of an overdraft, rocks' the arm counterclockwise. An arm 460 and shaft 463 connected by bevel gears to the arm 449 are thus rocked clockwise and through a finger 465 release a transfer lever 468 to add one to the negative wheel of lowest denomination. Similarly, when the positive side of the totalizer is engaged, the change in sign of the balance from negative to positive causes the disc 447 to rock the arm 460 and finger 465 counterclockwise to normal position, the restoring movement of the finger again releasing the transfer lever to add one to the positive wheel of lowest order. Auxiliary and balance totalizers, selecting. The auxiliary and balance totalizer lines are adjusted axially to select the required auxiliary totalizer, and the appropriate side of the balance totalizer, by a pair of cams 442, 445, Fig. 40, positioned by the differential mechanism of the first transaction bank. Means are provided automatically to break the latch of the first transaction bank when none of the keys 438 ... 440 in that bank is depressed. Conversely, depression of a key disables the automatic means. In an operation in which the " New balance " key alone is depressed, the balance totalizer is cleared and the amount standing therein is transferred to the appropriate " New balance " totalizer in the auxiliary line. For this purpose, a pawl 871, Fig. 24, controlled by the fugitive one mechanism, co-operates with shoulders 872, 873 on the latch plate 410, Figs. 21 and 24, for the first transaction bank, to break the latch in the zero or sixth position according as to whether the balance is negative or positive. If the " Proof " key is depressed in conjunction with the " New balance " key or the first read key 212 alone is depressed, the selection is the same but the auxiliary totalizer line is not engaged. In a reading or resetting operation for the front or rear line of totalizers, the latch is broken in the fifth position by a pawl 836, Fig. 21, abutting a nose 837 on the latch arm 410. This corresponds to a neutral position of the balance totalizer and one in which the engaging mechanism for the auxiliary line is ineffective. The pawl 836 is carried by an arm 834 and is positioned by the engagement of a stud 833 on the arm with a shouldered plate 830 set by the control plate keys 210 ... 212. In adding operations, the latch is automatically broken in the third or ninth position according as to whether the item is negative or positive. The latch plate is provided for this purpose with a shoulder 853 that abuts a pawl 852 if a debit key 143 is depressed, whereas if a positive key is. depressed the latch is broken at the end of its excursion in usual manner. Auxiliary and balance totalizers, engaging. Two separate mechanisms are provided for engaging the balance and auxiliary totalizers, one mechanism being actuated by the usual totalizer-engaging spider 275, Fig. 28, and the other by an "Add" cam 342, Fig. 30. Thus while one totalizer line is being engaged and disengaged according to reset timing, the other may be engaged and disengaged according to add timing, with the result that the amount cleared from one totalizer may be added into another in one operation. The balance totalizer is mounted in usual manner and has its engaging shaft 568, Fig. 28 operatively connected through sectors 564, 562 to an arm 560 carrying a stud 549. This stud may be engaged with a notch in a sector 574 rocked by the engaging spider 275, or with a notch
