Abstract: 511,437. Accounting machines. NATIONAL CASH REGISTER CO. Feb. 17, 1938, No. 4934. Convention date, Feb. 26, 1937. [Class 106 (i)] In a cash register or similar accounting machine having one of more rows of totalizers, and wherein totalizer-selection is controlled by keys. in adding operations and by manuallyadjusted levers in, total-taking operations, a total can be taken from a certain one of said totalizers without adjustment of the associated lever provided that a differential means has been set to a predetermined position during an immediately preceding adding operation. The invention is described as applied to a machine of the kind forming the subject-matter of Specifications 368,117 and 474,051, adapted for registering and classifying tax payments according to the kind of tax and the manner in which payment is made, the machine being provided with a multiple-item totalizer to sum the payments of different kinds of tax made by. an individual at one time, which sum is cleared into a selected "kind of payment totalizer, and with an accumulator into which the totals standing on the various totalizers are transferred for checking purposes. Item-entering and " New Balance " operations. The item is first. set up and is entered into a " kind of tax totalizer selected by depression of a key in one of the banks I, II, into a " New Balance " totalizer selected by depression of the " Deposit " key 31 in bank III, and into a multiple-item totalizer selected by the adjustment of the usual operatnon control lever 5 to " Add " position. The. keys of bank III serve as motor keys and the entered item is printed on a record strip, Fig. 10, line 1. The old balance; standing to the credit of' the individual for this particular kind of tax, is next set up, printed, Fig. 10, line 2, and, entered into the " New balance " totalizer now selected by depression of the " Old balance " key 32 in bank III. Although the multiple-item totalizer ds selected during this operation mechanism of the kind described in Specification 474,051 becomes operative to prevent its engagement. At the end of this operation, a differential member of bank III remains in " Old balance " position and frees the operation control lever 5 for adjustment to " New balance" position, whereupon the " New balance " totalizer selected by the differential member is reset and the total standing therein. is printed, Fig. 10, line 3. This, sequence of operations is repeated for each kind of tax in respect of which the individual is making a payment (three times in the example shown in Fig. 10). Multiple-item total-taking operation. After the payment or payments made by the individual have been entered. as above, the amount thereof is printed, Fig. 10, line 10, and transferred from the multiple-item totalizer, to the appropriate " kind  of payment " totalizer. This is effected by moving the operation control lever to "Add" position to select the multiple-item totalizer; adjusting a second operation control lever 4 to " Reset " position to condition the multiple-item totalizer for total-taking; and depressing the appropriate "kind of payment key 33 - - - -37 in bank III to condition the corresponding totalizer for addition and to release, the machine. Totat-taking and checking operations. At the end of a day or other period, the " kind of tax " totalizers are reset, and the totals standing therein are transferred to an accumulator situated in the same row as the multiple-item totalizer, , The accumulator is reset, and the totals standing in the "kind. of payment" totalizers transferred thereto. The accumulator is again reset, the agreement of the " kind of tax " total with the " kind of payment " total giving an indication that :the items' have been correctly entered. As is usual in this kind of machine, the series of total-taking operations must be preceded by an idle operation after which the totalizers are selected seriatim by the levers 1'- - 3. The accumulator is selected. automatically in these operations by the adjustment of the operation control lever 5 to "Reset" position. Total-taking from the accumulator is effected upon the adjustment of the' second control lever 4 also to "Reset" position. Interlock between operation control lever and differential of third totalizer-selecting bank. To enable a "New balance" operation to be effected without adjustment of lever 3, Fig. 1, to select the "New balance" totalizer, and to ensure that a "New balance" operation shall be possible immediately afteran old balance has been entered, an interlock is provided to. prevent adjustment of the control lever 5 to ''New balance position, unless the differential of bank III is in " Old balance " position. The interlock comprises a disc 201, Fig. 6, geared to the differential member 110 of bank III that remains in set position in the interval between successive, operations. A cam 208 is geared to the operation. control lever 5 and, in. the "Add" position of the latter, occupies the position shown. Adjustment of the control lever to "New balance" position is normally prevented by the abutment of a high-spot on the cam with a roller' 206 on a lever 204, counter-clockwise rocking of which is prevented by its knife-edge 203 beating against the periphery of disc 201. If the preceding operation has left the differential in "Old balance" position, however, a notch 202 is presented to the knife-edge and adjustment of the control lever to "New balance" position is permitted. During the ensuing "New balance" operation, the knife-edge locks the differential in "Old balance" position to select the "New balance totalizer. Selection of accumulator and multiple-item totalizer. These are arranged in the same row and selected by the position of the operation control lever 5, Fig. 1, which is geared for this. purpose to selecting drum 236, shown expanded in Fig. 8A. The arrangement is such that, in the "Add" position of the lever, the multiple-item totalizer is selected; in the "Reset" position, the accumulator is selected; and in the "Read" and "New balance" position, neither the' accumulator nor the totalizer is selected.
