Abstract: 443,786. Accounting-machines. KRUPP AKT.-GES., F., Essen, Germany. Sept. 5, 1934, No. 25543. Convention date, Sept. 8, 1933. [Class 106 (i)] An accounting - machine is provided with setting means to condition the machine to register the items of any one of a number of independent series of associated transactions, the arrangement being such that the sequence of the items in each series is forced and that, after an item of any one series has been registered, no fresh series of transactions can be initiated until all the remaining items of the selected series have been recorded. The invention is described as applied to a machine for dealing with cost accounts. The machine is capable of registering alternatively two series of items relating respectively to Mechanical Work (Series B) and Manual Work (Series A). The former series comprises three operations involving the entry into the machine an item of time (b1), an item of salary (b2) and an item of overhead charges (b3). This series is initiated by simply setting up the time item on amount keys 10, Fig. 4, and depressing a motor bar 12, the time totalizer being automatically selected. At the second and third operations, the salary and overhead totalizers are automatically selected in the order named, after which the machine is free to start a new series. The Manual Work series comprises time and salary items (a1, a2) only, the overhead charges for Manual Work being assumed to be constant for all classes of such work. This series is initiated by setting up the time on the amount keys and depressing a characterizing key 11 followed by the motor key 12. The time totalizer is automatically selected at the first operation and the salary totalizer at the second operation, after which the machine is free to start a new series. Manual work salaries are also accumulated in individual totalizers corresponding to the class of work and selected by the characterizing keys 11. An index 220 indicates on a chart 221 the kind of item to be entered at each operation. Totalizers. Two embodiments of the invention are described, in the first of which the totalizers are arranged in three lines, Fig. 3, separate totalizers being provided for each kind of item (a1, a2, b1, b2, b3) in each series (A, B). In the other embodiment, four lines of totalizers, Fig. 5, are provided, time and salary items of both series being accumulated in common totalizers (a1 b1, a2 b2) while individual totalizers are provided for mechanical salaries (b2) and overheads (b3). In addition, a grand totalizer G is provided to which totals may be transferred from the salary totalizer (a2 b2) and the overheads totalizer (b3). Both forms of the machine are provided with two lines of salary totalizers (I-XVIII) for the different classes of manual work. Keyboards. The keyboard of the second embodiment of the invention is shown in Fig. 4 and comprises amount keys 10, two banks of manual-work characterizing keys 11, two banks of headless keys 13, 15, 14, 112 automatically depressed to select the various main totalizers, the usual total-taking control lever 5, a motor bar 12 for initiating operations involving the entry of an item and a second motor bar 16 for initiating zero-amount and total-taking operations. The keyboard of the first embodiment is similar to that shown in Fig. 4 with the exception that the headless keys are arranged in a single bank. Printing totals. A totalizer is selected for total or subtotal taking by the positioning of an associated lever 1 ... 4, adjustment of the total lever 5 and depression of the motor bar 16. To transfer a total from the salaries totalizer (a2 b2) to the grand totalizer G, the lever 4 is adjusted to select the salaries totalizer and the motor bar 16 is depressed, the grand totalizer being automatically selected. Sequence of operations, enforcing-first embodiment. The headless keys 13<1>... 171, Fig. 2, for selecting the desired totalizer at each operation of a series, are themselves selected by the longitudinal adjustment of a slide 19<1> under the control of one or other of two cam grooves 34<1>, 35<1> in a disc 331 driven from the main shaft. The slide 191 is mounted on a second slide 22<1> depressible by the motor bar 12, and is provided with a number of projections 23<1> adapted in each position of adjustment to take over one of the key studs 24<1>. If no characterizing key 11 is depressed, the cam groove 34<1> becomes operative and the disc 33<1> rotates through 120‹ at each operation to select in a series of three operations the keys 13<1>, 141, 151 corresponding to the Mechanical Work totalizers (b1, b2, b3). On the other hand, depression of a key 11 at the first operation of a series, through a plate 28<1> rocks the connecting lever 311 to render the cam groove 351 operative, whereupon the disc 33<1> rotates through 180‹ at each operation to select in a series of two operations the keys 16<1>, 17<1> corresponding to the Manual Work totalizers (a1, a2). Sequence of operations, enforcing-second embodiment. The headless keys 13, 15, Figs. 4 and 6, for selecting the desired totalizer at each operation of a series, are themselves selected by the longitudinal adjustment of a slide 63 under the control of one of two cams 44, 45 driven from the main shaft 20. The slide has three positions. In the first or normal position, a forked member 66 pivoted to the slide embraces the stud 71 of the key 13 and takes under a stud 73 on a plunger 12<a> operated by the motor bar 12 ; the arrangement being such that depression of the motor bar depresses the key 13 to select the time totalizer (a1 b1). In the second position, no key is depressed and the zero stop pawl at 17 selects the salary totalizer (a2 b2). In the third position, a second forked member 67 pivoted to the slide becomes operative to depress the key 15 and select the overhead totalizer (b3). The control cams 44, 45 are driven from the main shaft 20 through a wide pinion 24 and differential gearing. The latter is so designed that if the Mechanical Work cam 44 is locked by a roller 91 engaging a recess 93, therein, the Manual Work cam 45 will rotate through 180‹ at each operation. Conversely, if the cam 45 is locked by a roller 92, the cam 44 will rotate through 120‹ at each operation. To disable the drive to the cams for operations other than those of a series, the wide pinion is carried by a pitman 26 and is moved to uncoupling position upon the depression of motor bar 12 and/or upon the adjustment of lever 4 to a total-taking position. The connection between the slide 63 and the cams includes links 61, 60, bellcrank 59, 57, a pair of arms 53, 54 having open-ended slots 53<a>, 54a at their free ends, and a pair of levers 47, 51 co-operating one with each cam and provided at their outer ends with studs 48, 52. In the position shown, the Mechanical Work cam 44 is selected by slot 53<a> embracing the stud 48, the cam 45 being locked at this time by its roller 92, the supporting bell-crank 89 for which is held against displacement by a stop 87 on a lever 75. However, if a characterizing key 11, Fig. 12, is depressed, a plate 84 rocks a yoke 79, and through a link 78, Fig. 6, rocks the lever 75 counterclockwise, thus disengaging arm 53 and engaging arm 54, and at the same time freeing the Manual Work cam 45 and locking the Mechanical Work cam 44 by superposing the stop 87 over a projection 88<a> on the bell-crank 88 carrying roller 91. Selection of Mechanical Work salaries totalizer (b2). This totalizer is selected by the depression of headless key 14, Figs. 4 and 11, under the control of a slide 114, carrying a pivoted arm 113 forked to embrace the stud 115 of the key. The arm 113 is rocked by the depression of the motor bar 12 through means including lever 109 pin-and-slot connected to the arm. However in all operations other than the second operation of a Mechanical Work series, the slide 114 is moved upwardly to disengage the arm from the stud. In a Manual Work series, the rocking of yoke 79 by depression of a characterizing key serves through a pitman 116 to move the slide, while in operations involving the depression of a headless key 13, 15 the slide is shifted by the clockwise rocking of an arm 122. Selection of grand salaries totalizer (G). The adjustment of the total lever 4, Fig. 4, to select the salaries totalizer (a2 b2) or the overheads totalizer (b3) depresses the headless key 112 to select the grand totalizer (G) into which the totals from the salaries totalizer are transferred. Interlock between amount keys and motor bars. A slide 171, Fig. 6, is provided with a projection 170 normally in position to lock the motor bar 12 by abutment with stud 73. However, upon the depression of an amount key, the slide is moved to free the bar 12 and interpose a second projection 174 beneath a stud 34 on motor bar 16 which is thereby locked. Manual Work characterizing keys 11. These keys, Fig. 12, co-operate with detent plates 151 that serve to prevent the depression or release of a key until the end of a series of operations, the plates 151 being locked by an arm 160 when either of the cams 44, 45, Fig. 6, is out of normal position. For this purpose, the bell-cranks 88, 89 carrying the rollers 91, 92 are provided with lateral projections 164, 165, that upon the counterclockwise rooking of either of them rock an arm 161 and interpose the arm 160 in the path of the plates 151. At the end of a Manual Work series, a projection 1461 on cam 45 rocks a lever 143<1> and, through a link 142<1>, shaft 120 and arms 153, 157, rocks the detent plates to release the depressed key. Totalizer-engaging mechanism. As items of time are not to be entered in totalizers of the first three lines, Fig. 5, the engaging mechanism for these lines is disabled during an operation involving the depression of headless key 13, Figs. 4, 6 and 18. The drive for the engaging-mechanism of these lines includes a pair of pinio
