Abstract: 455,290. Calculating-machines. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Christian, R. A.; 246, Telford Avenue, Ganger, J. R.; Rural Route No. 13, and Holt, E. E.; 729, Grand Avenue, all in Dayton, Ohio, U.S.A.) April 16, 1935, No. 11721. 'Convention date, April 16, 1934. [Class 106 (i)] A calculating-machine having an auxiliary actuating mechanism adapted to add a fixed amount to a particular totalizer at each operation of a certain nature is characterized in that the auxiliary mechanism is controlled by the travelling carriage, by the setting of an amount on the keyboard and by a manual control lever and in that means are provided for taking a total from the totalizer and subtracting this total from a balance totalizer. The invention is shown applied to an Ellis machine disclosed in Specifications 28253/08, [Class 106], 348,105, 420,807 ; and 424,132, [Group XVI], the totalizer actuated by the auxiliary mechanism being used to take account of a tax of two cents which is levied on certain cheques. The machine has four totalizers and prepares the ledger sheet shown in Fig. 1. An old balance is entered in the No. 1 or balance totalizer and printed in the first column. The amounts of cheques are then entered in the third column and subtracted from No. 1 totalizer. For each cheque entered, the fixed amount of two cents is added to No. 4 totalizer. The carriage is then moved to the fourth column, where No. 4 totalizer is automatically set for total-taking. The total tax is thus printed and at the same time subtracted from No. 1 totalizer from which a total is later taken and printed in the new balance column. Auxiliary actuating mechanism. The two units are added to the cents wheel only if an amount representing a cheque is entered into the machine, the auxiliary mechanism remaining inactive unless one or more of the main differential actuating bars 42, Figs. 7 and 8, move a cross-bar 145 secured to a lever 144 which rocks anticlockwise a lever 137 to hook its end over a pin 138. The lever 137 is pivoted to a lever 133 and the pin 138 is attached to a lever 139 rocked anticlockwise during the machine operation. The lever 133 is thus turned clockwise about its pivot 118 and pulls with it by a spring 134 a lever 117 which lowers a pawl 120 to release a latch 124. A spring 168 thereupon rocks a lever 128 to turn a segment 132 gearing with the units of cents wheel of the No. 4 totalizer to advance the wheel by two units. The No. 4 totalizer is also controlled by a flying lever 90, Fig. 4, pivoted to an operating plate 89. Towards the end of the initial clockwise movement of the operating plate, after the auxiliary mechanism 132 has added the two cents to the units wheel, the end 111 of the flying lever, after depressing a byepass pawl 83, engages a lever 81 whereby the totalizer is engaged with the ordinary actuating racks while the latter are stationary at the end of their outward movement. The lever 128 and sector 132 are then restored by a bar 170. The totalizer is disengaged from the racks and re-engaged with the sector, before the racks commence their return movement, by the lever 90 engaging the byepass pawl 83 during the initial return movement of the plate 89. Manual control of auxiliary mechanism. A finger lever 77 can be moved so that its end 76 engages another notch 79 of the lever 81, the lever 81 and the pawl 83 then rocking out of the path of the lever 90 so that the No. 4 totalizer is engaged with the ordinary actuating racks in the normal manner. At the same time, a link 112 connected to the lever 81 moves a blocking member 115 over the end 116 of the lever 117 so that the action of the auxiliary mechanism is inhibited. Carriage control of auxiliary mechanism. The two cents tax is added by the auxiliary mechanism only when the carriage is in the " cheques " position and accordingly in this position a cam depresses a lever connected by links to another blocking member similar to the member 115. This other member is thus moved out of the path of the lever 117. Total-taking from tax totalizer. When the carriage is moved to the fourth column, the tax (No. 4) totalizer is automatically conditioned for total-taking, the total tax thus being printed. A cam on the carriage depresses links 202, 200 to rock a lever 197 connected to a link 191, the end of which engages a pin 192 on a lever 193. This pin controls the No. 4 total cam 196. When the finger lever 77 is moved to " off " a projection 188 on the lever 81 lowers the link 191 below the pin 192 so that totaltaking in No. 4 totalizer is controlled by the key 224 in the normal manner. " Tax-exempt " key. Certain cheques are exempt from tax, and when such a cheque is entered a " tax-exempt " key is depressed. This key moves to the right a link 231, Fig. 4, to rock a shaft 178 having an arm 179, Fig. 10, connected by a link 180 to a blocking member 181 which is thus moved to prevent operation of the auxiliary-mechanism controlling arm 117. The arm 179 is also connected by a link 182 to a type sector 186 which prints the symbol " EX " against the amount of each exempted cheque. Other manual control means. Sometimes a number of cheques are secured in a bundle with the number and total amount noted thereon. The total amount is then entered in the cheque column and the action of the tax totalizer prevented by depressing a key 171, Fig. 10, marked " L.S." This key moves a link 175 to the right to rock the arm 179 whereby the blocking member 181 is brought to active position. The carriage is then moved to the " tax " column, the total tax (computed mentally) being set on the keyboard and the key 171 again being depressed. This last action rocks the shaft 178 so that an arm 213, Fig. 4, moves a link 212 to push the link 200 off the lever 197. The carriage cam thus does not condition the tax (No. 4) totalizer for total taking.
