Abstract: 648,389. Accounting-machines. NATIONAL CASH REGISTER CO. July 23, 1947, No. 19755. Convention date, Feb. 3, 1942. [Class 106 (i)] In an accounting or similar calculating machine including a printing mechanism adapted to print on an inserted record material, an adjustable table for supporting the record material, a positioning device for the table adapted to select a line on which a first print is to be made, linefinding keys to control the positioning device and an automatic step-by-step feeding mechanism for the table, the provision of selectively operable devices adapted to control the step-bystep feeding mechanism in such manner as to cause the table to be fed, in a machine operation, either before or after printing occurs in that operation. General. The invention is applied to a motor - operated machine of the Shipley type for bank transactions. The machine prints on an audit strip and on a statement sheet which may be of any of four different sizes according to whether or not certain information is to be printed in duplicate or other information is to be printed at all. A set of type wheels, positioned through ring- gears by the differential mechanisms, is provided for each column of the two record materials. Cheques and deposit slips may be held in a partitioned box 137, Fig. 1, supported on a table 136 hinged to the machine stand. Specifications 280,828, [Class 100 (iv)], 407,380, 447,481, 605,926, 629,707 and 648,390 are referred to. Totalizers. An add-subtract totalizer comprising pairs of wheels geared together for reverse rotation is arranged on an upper line and two similar totalizers, into which the values of debits, debit-corrections, deposits and deposit-corrections are entered, are arranged on a rear line together with two add totalizers for registering the totals of new positive and negative balances respectively. Main keyboard, Fig. 2. Ten rows of amount keys 152 are provided to the left of which are four rows of keys 151 on which the number of cheques in a bundle may be set to be entered in a cheque-counting mechanism (not described) of the type disclosed in Specification 629,707. On the extreme left of the keyboard are two rows of keys 150 on which the day of the month can be set to be printed with the month and the year which are set by levers 148, 149, Fig. 1. The ten rows of amount keys 152 and the three left-hand rows of keys 151 are also used in analysis operations and oil them may be set simultaneously various relevant data. To the right of the amount keys is a row of keys comprising seven symbol-printing keys, an " Eject " key which causes the statement sheet to be ejected at the end of an operation, a non-count key NC which disables the automatic chequecounting mechanism and which, if none of the other symbol-printing keys are simultaneously depressed, causes the symbol NC to be printed, and a " Balance Forward " key which causes an amount entered in a pick-up operation to be printed. Transaction keys 154, 155, 157, 159, 161 and 162 are starting keys which select appropriate totalizers for actuation. An " Analysis " key 156 in this row, also a starting key, disengages all of the totalizers while the " Space " key 160 simply causes the statement sheet and audit strip to be spaced. An " Overdraft " key 158 is not a starting key but is used, when an overdraft occurs, to unlock certain other keys. Of the total keys, a " New Balance " starting key 163 causes an amount on the balance totalizer to be transferred to a grand totalizer in a known manner (not described). " New Balance (non-transfer)," " Sub-Balance " and " Indicate Balance " starting keys 168, 164, 165 cause the amount in the balance totalizer to be printed, with or without being cleared, or indicated, respectively. Keys 166, 167 are used with certain of the transaction keys to cause sub-totals or totals to be taken from the corresponding totalizers. Operation of a lever 171, Fig. 1, releases all depressed keys except starting keys. Symbol repeat lever. A depressed symbol key is held depressed during an ensuing operation by a detent 257, Fig. 21, having projections adapted to co-operate with pins 262 in the stems of the keys. Normally, when a keylocking shaft 139 is rocked counter-clockwise near the end of an operation, an arm 264 is rocked counter-clockwise, by a torsion spring which connects it to an arm (not shown) fast on the shaft 139, so as to cam the detent 257 downwardly to release the depressed key. However, if a hand-lever 169 has been rocked counter-clockwise, a stud therein will have moved an arm 289 clockwise into a position in which counter-clockwise movement of an arm 265 having a projection 269 is blocked. The arm 265 is secured to the arm 264 which is thus prevented from camming the detent to release a depressed key. Locking of pick-up keys. Projections 313, 314, Fig. 17, on a bar 310 pivoted to arms 311, 312 are normally in the path of pins in the stems of the pick-up keys 154, 162, Fig. 2, to prevent depression of these keys. However, during a " New Balance " or " New Balance (non-transfer) " operation, the total control plate is so positioned that a cam slot 323 therein, in co-operation with a stud 324 in an arm 325, rocks a lever 364, having a slot embracing the stud 324, counter-clockwise. The lever 364 engages a stud 365 in the arm 311 so as to move the bar 310 downwardly in which position it remains at the end of the machine operation to permit depression of the pick-up keys. After operations other than " New Balance " operations, the pick-up keys may be released by rocking a hand lever 170 clockwise. A second locking-bar (not shown) is pivoted to the lever 170 and to an arm similar to the arm 312 and is thus moved downwardly by operation of the lever 170 so that projections on this bar enter the paths of pins in the stems of all of the transaction keys except the pick-up keys. At the same time, a projection on the underside of the bar engages a stud 321 in the bar 310 which is thus also moved downwardly to free the pick-up keys. Keyboard interlocks. Depression of the " Overdraft " key 158, Fig. 10, causes a pin in the key-stem to cam a slidably-mounted sprung detent 421 downwardly so that projections 429, 430 on the detent enter the path of pins in the " Cheque " and " Deposit " keys respectively to prevent depression of these keys. When any one of the " Deposit-Correction," " Analysis," " Space " or " Cheque-Correction " keys is depressed, a stud 401, Fig. 20, in its stem engages a projection in a slidable bar 366 to cam the latter; and a bar 367 secured thereto by a pin 370, downwardly. Projections on the bar 367 are thus moved into the paths of pins 489 in the stems of the total keys so as to prevent depression of the latter. When any one of the total keys is depressed, the pin in the key-stem engages a projection in a slidable bar which is bifurcated to embrace a stud 384, Fig. 17, in a lever 439 and the lever 439 is rocked counterclockwise, a surface 440 thereon co-operating with a stud in the arm 312 to which the locking bar 310 is pivoted so as to move this bar downwardly. The pick-up keys are thus freed to enable one or other side of the balance totalizer to be selected in a total- or sub-total-taking operation. Differential mechanism of transaction and symbol keys. The transaction keys control a differential mechanism of the Shipley type which positions a segment 353, Fig. 6, connected by a tube 244 to another segment (not shown) which is connected by a link to two cams serving to move the upper and back totalizer lines laterally to select the appropriate sets of totalizer wheels for actuation. Depression of the " Overdraft " key moves a pin 401 in the key-stem into the path of a projection 400 on a detent 385 to prevent the normal clockwise rocking of the detent under the action of a spring when a stud 387 in a yoke 388, which is rocked counter-clockwise at the beginning of an operation by an arm 399 on the key-locking shaft 139 through a link 398, is moved away from an arm 386 of the detent. A yoke 393 connected to the detent by a link 391 is thus held stationary so that an arm 395 thereof blocks movement of a lug 396 in a plate 397 integral with an arm 328 which is slotted to embrace a pin 337 of the latch carried by the differential arm. The latch is thus broken when the differential mechanism reaches its first position to align the negative side of the balance totalizer and the " Total New Balance Minus " totalizer with the amount differential mechanisms. Depression of either the " Deposit-Correction " or " Cheque-Correction " key causes a stud in the key-stem to engage a cam surface on a slidable bar (Fig. 16, not shown) to move the bar downwardly. A surface on the lower end of the bar engages a pin in a zero stop for a differential mechanism of the Shipley type associated with the symbol keys. The zero stop is thus cammed to an inoperative position and the differential mechanism moves its full extent to cause an errorcorrection symbol to be printed. Indicators. Each transaction as it is entered is indicated on drums 298, Fig. 1, driven from ring gears which set the type wheels in known manner and which are themselves set by the amount, symbol and transaction differential mechanisms. The balance on the balance totalizer may be indicated by depressing the " Indicate Balance " key. Overdraft mechanism. When an overdraft occurs on the balance totalizer, the highest order " plus wheel 300, Fig. 9, is driven counter-clockwise by the associated " minus " wheel from the " zero " to the " nine " position. During this movement a cam 403 secured to the wheel 300 engages a projection 437 of an arm 407 to rock the latter, and an arm 405 connected thereto by a rod 410, clockwise. A bifurcated arm 411, fast on a shaft 412, embraces the rod 410 so that this shaft is also rocked clockwise. An arm 413, Fig. 10, thereon is thus moved from a normal position in
