Abstract: 459,224. Accounting-machines. NATIONAL CASH REGISTER CO., Ltd., 225, Tottenham Court Road, London.- (National Cash Register Co. ; Dayton, Ohio, U.S.A.) April 3, 1935, No. 10307. [Class 106 (i)] A cash register or similar accounting- machine having a balance totalizer and individual totalizers for accumulating amounts relating to one kind of accounts, is provided with a number of total retainers for accounts of another kind and a second balance totalizer for co-operation therewith, means being provided for variously selecting the totalizers and retainers, and the arrangement being such that of a series of amount entries made in respect of the first kind of account, at least one is automatically entered into the second balance. totalizer from which the total is automatically transferred during a balance operation to a selected retainer. The invention is described as applied to a machine for dealing with the usual series of accounting transactions, namely, the entry of an old balance followed by items of deposit and withdrawal, and the taking of new balance. The machine is provided, as is usual, with a balance totalizer I, Fig. 2b, controlled by a lever 4, Fig. 1, a line of totalizers II controlled by keys 11 ... 16 for summing the positive and negative old and new balances, the deposits and the withdrawals, and a multiple-item totalizer III controlled by a key 17. However, the usual line of totalizers for analyzing the items is replaced by a battery of total retainers V, each comprising a series of denominational racks longitudinally positioned in accordance with the digits of the total and a slide positioned in accordance with its sign. The retainers are mounted in a vertically adjustable housing in five horizontal rows of ten, and are selected by keys 19 for the row and keys 20 for the retainer in the row. To prepare the machine for an old balance operation, the amount is set up on the keys 10, the appropriate old balance key 11, 12 is depressed, and a key in each of the banks 19, 20 is depressed to select a retainer, these retainer keys being held depressed until the end of the series of operations. Now, upon the depression of the motor bar to initiate the operation, the old balance is entered into the balance totalizer I and into the old balance totalizer in line II, in usual manner. Also during this operation, the row of retainers selected by the depressed key 19 is positioned in horizontal alignment with a second balance totalizer IV and is shifted bodily to the left to a position V<1> in which its racks overlie the actuator pinions of the totalizer, which pinions are disengaged from the differential actuators during this operation. The racks of the retainer selected by the depressed keys 20, are now engaged with the actuator pinions, and finally, the amount standing on the retainer is transferred to the appropriate side of the totalizer by the zeroizing of the retainer. Items are entered in the usual manner into the balance totalizer I, the selected totalizer II, and also into the second balance totalizer IV, but not into the selected retainer which, though still in selected position, is not engaged with the actuator pinions during this operation. A new balance operation is initiated in usual manner, and the balance transferred from the balance totalizer I to the appropriate new balance totalizer on line II. The second balance totalizer IV is also zeroized and the amount standing therein transferred to the selected retainer and its slide set according to the sign. Finally, the row of retainers is returned to the right into the housing, and the retainer keys 19, 20 are released. Keyboard. The machine is provided with the usual amount keys 10, positive and negative old balance keys 11, 12, deposit and withdrawal keys 13, 14, headless new balance keys 15, 16, multiple-item key 17, balance lever 4, operation-control lever 5, and motor bar 18. In addition, banks of keys 19, 20 are provided, respectively to select a row of total retainers and a retainer in the selected row. Keys depressed in these banks are held depressed for a complete series of operations by means not shown. The motor bar has positive and negative stems selected for operation by the keys 11 ... 16 and in turn selecting the appropriate side of the balance totalizer I in the manner set forth in Specification 368,117. Differential mechanism. The differential mechanisms for all the banks are similar and of the kind described in U.S.A. Specification 1,899,455. The differential mechanism of an amount bank is shown in Fig. 2a, and comprises a pair of scissor arms 21, 22 driven by a planetary gear so as to converge on a zero stop-pawl 220 or the stem of a depressed key. A toothed sector 245, by its stud 246, is positioned by the scissor arms and sets the type wheel for the bank. The upper scissor arm 22 is geared to an actuator rack 23 having sets of teeth 241 for each of the totalizers I ... IV, Fig. 2b. Balance totalizer I. This is in all respects similar to that described in Specification 368,117. Totalizer line II. On this line are the totalizer for the positive and.negative, old and new balances, the deposits and the withdrawals. The totalizers are of known construction, and are selected by the keys 11 ... 16, Fig. 1, through the differential mechanism shown in Fig. 15. Multiple-item totalizer III. This may be of similar construction to the totalizers of line II or may be a balance totalizer, and is selected by depression of the multiple-item key 17, Fig. 1. Balance totalizer IV. This totalizer receives the total standing on the selected retainer in an old balance operation, modifies this amount according to the items entered and returns the new total thus formed to the retainer. It is in many respects similar to that described in Specification 368,117, but differs in detail. It is provided in each denomination with a positive wheel 75, Figs. 12, 13, or 22, and a negative wheel 80, geared together in usual manner for rotation in opposite directions on a common shaft 68. The wheels are driven by pinions 65a mounted so as to be rotatable on, but axially immovable of, a shaft 66, which shaft is axially adjustable to select the positive or negative wheels of the totalizer and is rockable about the shaft 68 to engage the pinions with the actuator racks 23. This latter movement is effected by cams driven only in item-entering operations. Rigid with each actuator pinion 65<a> is a wide pinion 65 adapted to co-operate with a denominational group of racks 33 of the selected row of retainers and with a resetting rack 145, Figs. 2a and 2b. Transfer mechanism.-The transfer mechanism for the second balance totalizer IV differs from that described in Specification 368,117, and comprises for each denomination a threetoothed pinion 601, Figs. 12 and 13, rotatable on a shaft 109 adajcent the totalizer shaft 68. At transfer, the transfer tooth 603 of the selected totalizer wheel 75, 80 rotates the pinion through one sixth of a revolution. Later in the operation, the pinions thus rotated are moved seriatim through a further sixth of a revolution by cams 605 on a shaft 55. This second movement through gears 607, 609, shaft 608, arm 611, and roller 614, steps forward a wheel (not shown) on shaft 109, and through a gear 616 and actuator 65 adds one unit to the totalizer wheel of next higher order. In alternate denominational stages of transfer the totalizer pinion is connected through the gear 607 and a gear 621, to actuating arms on a shaft 620, these arms being similar in all respects to the arms 611. Fugitive-one mechanism. This is similar to that described in Specification 368,117. A transfer mechanism similar to that described above is applied to the wheels of highest order and, when the selected wheel moves from 9 to 0, serves to rotate the shaft 620, Fig. 12, through 90‹. If this action is occasioned by a change in the sign of the balance, arms 623, mounted on and flexibly connected to the shaft 620, add one unit to the selected wheel of lowest order. On the other hand if the action is occasioned by the capacity of the totalizer being exceeded, the arms 623 are restrained by a stop 637 that abuts one of a pair of projections 635, 636 rigid with the arms and situated diametrically opposite one another, and in different planes. Total retainers V. The retainers are arranged in a housing 28, Figs. 2b, 22 and 27, in five horizontal rows each of ten retainers. The housing is counterweighted and positioned vertically by a differential mechanism, Fig. 27, controlled by the keys 19, the differentially set member 672 being connected through gearing including shafts 678 to a gear 36 meshing with racks 37 on the housing. The housing is set during an old balance operation, and locked by a latch 691 until the end of the series of operations. Each retainer comprises a series of denominational racks 33, Figs. 2b and 22, the racks of the same denomination in a row being grouped together to co-operate with the extensions 65 of the actuator pinions 65<a> of the second balance totalizer IV. In addition, each retainer has associated therewith one of a group of plates 122, Figs. 15 and 22, that has a rearward or forward position according as to whether the total standing on the totalizer is positive or negative. The racks and plates of each row of retainers are mounted for horizontal sliding in a frame 47 that is in turn mounted for slight vertical movement in a carriage 25, the frame 47 being normally held in upper position by springs. The selected carriage 25 is slid forwardly out of the housing 28 to the position V<1>, Fig. 2b, during an old balance entering operation, and is returned at the end of the subsequent new balance operation. The sliding is effected by rollers 38, 38<a> driven by partial gears 39, 39<a>, Fig. 2b, the carriage being held in its end positions by spring arms 29, 45. The totalizer in the row is selected by the key bank 20, th
