Abstract: 474,051. Accounting-machines. NATIONAL CASH REGISTER CO. April 24, 1936, No. 11712. Convention date, April 24, 1935. [Class 106 (i)] In a cash register or similar accounting- machine having means for disabling the totalizerengaging mechanism for a line of totalizers containing a selected totalizer, the selection of a totalizer shifts a coupling member laterally into engagement with rockable totalizerengaging means, such coupling member being normally connected to driving means but being adapted for disconnection therefrom in certain types of machine operation. The invention is described as applied to a machine for use in registering and recording tax payments wherein it is desirable to print certain items with symbols designating the cashier, kind of tax and so on, without adding the item into the totalizers corresponding to some or all of those symbols. In such operations, the symbols are set up by depressing totalizerselecting keys, whereby the totalizers corresponding to the symbols are selected in usual manner. According to the invention, however, means under the control of one of the depressed keys or of the operation control lever, become effective to cripple the engaging means for a totalizer line containing a selected totalizer into which the item is not to be added. Keyboard and operation. The machine is provided with a keyboard of usual type including amount keys 10, four banks of totalizer-selecting keys 11 ... 14, each associated with a line of totalizers, and an operation control lever. The first two banks, 11, 12 of totalizer-selecting keys are used to classify the items according to the kind of tax, the third according to the manner of payment, and the fourth according to the cashiers who effect the operations. The machine is normally released after the depression of a key 11 or 12, a key 13 and a key 14, the last serving as a motor key. The key banks for the kind of tax each include a refund key 15, 16 controlling a totalizer wherein are accumulated the items relating to refunds in connection with those kind of tax designated by the keys of the opposite bank. In an operation in which one of these refund keys is depressed, the item is entered into the totalizer selected by that key and the appropriate symbol is printed, the symbols corresponding to the totalizer selected by the depressed keys in the remaining three banks are also printed, but these totalizers are not engaged. In a similar manner, depression of a key 17 or 18 in the third bank effects the engagement only of the associated totalizer for fees or interest, while permitting the symbols corresponding to all the depressed keys to be printed. Adjustment of the operation control lever 5 to position for duplicating enables all the printing mechanisms to function while disabling the engaging mechanism for all the lines of totalizers. Totalizer selection. The totalizers 53, Fig. 5B, of each line are selected in known manner by a cam drum 40 adjusted by the differential mechanism of the associated bank of totalizerselecting keys. The setting of the cam is transmitted through the usual plate 42, shaft 43 and plate 46 to the rider shaft 51. Totalizer engaging-mechanism. The totalizer driving-pinions 54, Fig. 5B, are engaged with and disengaged from the actuators in usual manner by the rocking of a shaft 50 driven by a plate 60, Figs. 3 and 5B, that is oscillated by cams 63 rotated by the usual timing mechanism 69 adjusted by the operation control lever 5. The plate 60, in the present machine, is freely mounted on the shaft 50, but may be connected thereto by a coupling pin 57 when the latter is shifted into an aperture in a plate 85 secured to the shaft. The coupling pin is carried by two arms 81, 82 of a hub 80 of shaft 50, passes through elongated apertures in the plate 42 and wall 44, and is displaced longitudinally as the plate 42 moves to the left to select a totalizer. In the normal position of the parts shown, no totalizer in the line is selected and the coupling pin is coupled to the plate 60 by a boss 83 of arm 82 engaging within the large part of a keyhole slot 61 in the plate. However, in this position, the coupling pin does not engage plate 85 which, with the shaft 50, is locked by a pin 56 projecting from plate 46 to prevent engagement of the totalizer line. In an operation in which a key of the associated bank is depressed, the plate 42 is shifted to the left to select the appropriate totalizer and, in so doing, engages the pin 57 with the plate 85 to enable the totalizer line to be engaged in usual manner. If, however, in spite of totalizerselection, it is desired to suppress totalizerengagement, the hub 80 is moved to the right whereby the boss 83 is disengaged from the oscillating plate 60, and the coupling pin 57 is locked against lateral movement by a stud 135 entering an aperture 136 in the frame 44. Totalizer engaging-mechanism, crippling. The means for shifting the hubs 80, Figs. 3 and 5B, to disable the engaging-mechanisms for the associated totalizer lines, is controlled by the keys 15 ... 18 and the operation control lever 5. Depression of one of these keys or the adjustment of the operation lever to duplicating position serves, through cam plates 127 ... 130, Fig. 3, to shift an associated pitman 122 ... 125 to the right. A stud 117 ... 120, Fig. 6, on the shifted pitman, by co-operation with cam slots 112 ... 115 in a group of four control plates 108, moves selected plates to the left to interpose abutments 110 on those plates in the paths of levers 99, Figs. 3, 6, 8, pivoted on a shaft 100. At the beginning of each operation, a stub shaft 97, carrying four levers 96 each pin-and-slot connected to a lever 99, is rocked clockwise about the shaft 100, whereby those levers 96, which are connected to levers 99 that are blocked by the abutments 110, actuate links 93 and by cams 91 shift the associated hubs 80 to cripple the requisite totalizerengaging mechanisms.
