Abstract: 475,185. Cash registers. NATIONAL CASH REGISTER CO. Feb. 12, 1936, No. 4221. Convention date, Feb. 15, 1935. [Class 106 (i)] In a cash register or similar accounting-machine having means for transferring a total from one totalizer to another in the same row in one continuous machine operation, a total may now be transferred from one totalizer in the row selectively to any one of the other totalizers in the row. The invention is described as applied to a machine having a multiple-item totalizer disposed in the same row as the transaction totalizers, the arrangement being such that when a multiple-item total is taken, the multiple-item totalizer is reset and the total standing therein is transferred to one of the transaction totalizers selected by a depressed key. For this purpose, the transaction totalizer row is engaged in accordance with subtotal timing, the multipleitem totalizer being selected during the first half of the cycle under the control of the usual operation control lever set to multiple - item position. At the end of the first half-cycle, the control lever is automatically restored to "Add" position whereby the selected transaction totalizer is brought into position for engagement during the second half of the cycle. Keyboard. The machine is provided with amount keys 11, Fig. 1, department keys 12, clerks' keys 13, 14, transaction keys 15, including a " No Sale " key W, a motor key 16 for use in multiple-item transactions, a multiple-item total key 17 and an operation control lever 18. Totalizers. Four rows, each of four interspersed totalizers 218, Fig. 3, are mounted in frames 249 slidable and rockable on shafts 149 for selection and engagement. The first two rows contain the totalizers controlled by the keys 13, 14, respectively, of the clerks' bank. The third row contains the department totalizers, and the fourth row the multiple-item totalizer and three transaction totalizers, namely, one for the transactions Cash " X " and Paid on Account " R," and one each for the transactions Paid Out " A " and Charge " C ". Differential mechanism. The differential mechanism for the amount banks is of the kind described in Specification 466,118 and sets the totalizer actuators, indicator drums and typewheels in the manner set forth in that Specification. The differential mechanisms, Figs. 3, 6 and 17, for the totalizer-selecting banks are of the same type, but in place of actuator segments set by the differential arms 201, are provided with totalizer-selecting segments 239 set by the beams 208. These differential mechanisms are driven during the first quarter of the machine cycle and restored during the fourth quarter, whereas the amount differentials are driven and restored during the second and third quarters respectively. Sequence arrangements. In adding operations, a clerks' key 13, 14, Fig. 1, and a department key 12 must first be depressed, after which the amount is set up and the machine is released by depression of one of the transaction keys 15 that also act as motor keys in single-item operations. In multiple-item operations, however, wherein the operation control lever is adjusted to position T, the machine is released by depression of a motor key 16, the selected transaction key remaining depressed until a multiple-item total is taken by depression of key 17. With the operation control lever in position for taking a total or subtotal, the depression of any totalizerselecting key serves to release the machine. Interlock between the amount keys and the department and clerks' keys. Depression of amount keys, through cam plates in the associated banks, rocks a shaft 47, Fig. 21, counterclockwise. This rocking is normally prevented, and the amount keys thus locked, by a lever 50 that intercepts an arm 49 of the shaft. Depression of a department key, through a cam plate 61, removes the lever from the path of the arm and releases the amount keys. Similar means are provided to make the release of the amount keys also dependent upon the depression of a clerks' key. Interlock between the amount and transaction keys. Depression of a transaction key 15, with the exception of the "No Sale " key W, is normally prevented by a detent 165, Fig. 17, raised to inoperative position upon the rocking of shaft 47 by the depression of an amount key. Interlock between the two groups of clerks' keys. Simultaneous depression of a key 13 and a key 14 in the clerks' key bank, with consequent selection of both the clerks' totalizer rows for engagement, is prevented by a pair of detents 23, 24, Fig. 3. Machine release. The main shaft 112, Fig. 23, is normally locked by an arm 108 of a lever 105 rocked clockwise upon the release of a pitman 102 to the action of its spring 106. The pitman is normally restrained by the abutment of its roller 100 with a surface 99 of a lever 97 urged clockwise about its pivot 96 by a spring 98. Upon the clockwise rocking of a latch 94 about a shaft 81, the lever 97 is freed and the roller 100 enters a recess 115 therein, the consequent movement of the pitman rocking the lever 105 and releasing the machine. After a complete rotation of the main shaft, the lever 105 is restored by a pin 110 wiping past an arm 107 of the lever. Machine release by transaction keys. Depression of a transaction key 15, Figs. 1 and 22, lowers a detent 67 and rocks a lever 74 clockwise about a pin 76 on a link 77, whereby a stud 78 on the lever rocks a slotted arm 80 about the shaft 81 to disable the latch 94, Fig. 23, and release the machine. This release device is disabled in multiple-item operations by a cam 279, that is set by the control lever 18 into a position in which it lowers the pivot pin 76 into the wide part of a slot 75 in the lever 74. Machine release bv motor kev 16. The motor key 16 is normally locked by a detent 283, Fig. 17, but is released upon the adjustment of the operation control lever to multiple-item position, when a stud 336, Fig. 20, on the lever rocks an arm 325 coupled to the detent. The depression of the motor key raises a detent 289, Fig. 22, and, through a link 292 and the stud 78, rocks the arm 80 to release the machine. Machine release by totalizer-selecting keys in total-taking operations. The clerks' and department key banks are each provided with a machine release device similar to that for the transaction bank, with the exception that the pins 76 for these banks are only raised into effective position when the control lever is adjusted to subtotal or total position. Release of totalizer-selecting keys. Towards the end of each operation a shaft 301, Fig. 21, is rocked clockwise and through an arm 302. pawl 303 and stud 314 raises the detent 53 to release the department keys 12. However, upon the adjustment of the control lever to multiple-item position, the release means is disabled by a cam 417 that permits a link 312 to rise and the pawl 303 to swing counterclockwise to ineffective position under the action of its spring 304. Similar release means are provided for the keys of the clerks' and transaction banks. Totalizer engaging-mechanism. The totalizer rows are rocked to engage selected totalizers with the actuators by means of a disc 119, Fig. 13, to which the totalizer rows may be coupled and which is given a clockwise and counterclockwise excursion during each machine operation in accordance with adding, subtotal-taking or total-taking timing according to the position of the operation control lever. The control lever co-operates for this purpose with cam slots in levers 188 (of which one is shown in Fig. 20) whereby the disc is selectively coupled to arms. 186 oscillated in accordance with the various timings by cams on the main shaft 112. The totalizer rows, as previously stated, are mounted in frames carried by shafts 149. Each shaft has an arm 150 to which is pivoted a lever 148 having a stud 154 engageable within an associated slot 155 in the disc 119. The movement for engaging the stud in the slot is derived from a release shaft 117, connected to the lever 105 for counterclockwise rocking when the machine is released. The connections between the release shaft and each lever 148 include a link 137, floating lever 136, link 139, lever 141, link 142, lever 144 and link 145. The pivot 135 of the floating lever is carried by a lever 134 rockable about a shaft 133, the linkage being effective to move the stud 154 into the slot 155 if the lever 134 is locked and ineffective if the lever is free. The stud 154<111>, Fig. 11, for the transaction totalizer line is held in adjusted position by a cam-actuated pawl 1144 during each machine operation. Clerks' totalizers selecting-mechanism. The clerks' totalizers are arranged in two rows, the appropriate row being selected by the detents 23, 24, Fig. 3, of the clerks' bank. For this purpose, the detent '23 is connected through an arm 121 and bail 183 to an arm 124, Fig. 13, that is in turn connected through a lever 128 and link 129 to a hook 130 pivoted on the release shaft 117. The arrangement is such that when one of the clerks' keys 1 ... 4 is depressed, the detent 23 is raised and the hook 130 rocks counterclockwise to lock the lever 134, and cause engagement of the first totalizer row. A similar mechanism causes engagement of the second totalizer row when one of the clerks' keys 5 ... 8 is depressed. The appropriate totalizer in the selected row is selected by a cam drum 231, Fig. 3, that set by the differential mechanism of the clerks' bank and has two cam grooves serving to position the totalizer frames 243, 248 axially on their shafts 149. The clerks' totalizers are not engaged in "Paid Out " and " Charge " transactions. Upon depression of the transaction key A or C, corresponding to these transactions, a detent 180, Fig. 13, is raised and rocks the pivots 127 of the levers 128 to the right, thus disabling the hooks 130 in spite of the depression of the cler
