Abstract: 452,414. Accounting-machines. KRUPP AKT.-GES., F., Essen, Germany. Dec. 19, 1934, No. 36396. Convention date, Dec. 20, 1933. [Class 106 (i)] Machines for dealing with multiple-item transactions. In a cash register of the kind having a multiple-item totalizer and a number of classifying totalizers and wherein each item is entered into the appropriate classifying totalizer whether it is a single item or forms part of a multiple-item transaction, engagement of the multiple-item totalizer is controlled by a pair of differently timed control members for addition and total-taking respectively, a single coupling member being provided to couple the engaging means to one or other of the control members according as to whether a multipleitem conditioning member or multiple-item total-taking means has been actuated. Keyboard. In addition to the usual amount keys 10, Fig. 1, and operation control lever 20, the machine is provided with a bank of special keys 11 ... 19 of which keys 11 ... 14 are characterizing keys for the transactions " Cash," " Accounts Paid," " Charge to Account " and " Paid Out," respectively, key 15 is a multipleitem key, keys 16 ... 18 are item-total keys for the first three classes of transaction, and key 19 is a " No Sale " key. Machine release. The machine is released to effect a singe-item operation by the depression of the appropriate transaction key 11 ... 14. In multiple-item operations, the multiple-item key is first depressed followed by the appropriate transaction key. During subsequent entries of the series, the multiple-item key is held in depressed condition and all inappropriate transaction and item-total keys are locked. Depression of the appropriate item-total key releases the machine to zeroize the multiple-item totalizer (the operation control lever remaining in " Add " position). During this operation. all the transaction keys are locked and at the end of the operation released together with the multiple-item key. The release mechanism comprises a detent 51, Fig. 7, that is moved downwardly upon the depression of any special key other than the multiple-item key. The movement of the detent disables a latch 55, thus releasing a pitman 57 and allowing a lever 58 to rock clockwise. An arm 558 of the lever is thus removed from the path of a stud 61 on a disc 62 rigid with the main drive shaft 63 and the machine released. After a complete rotation of the shaft, a stud 662 on the disc wipes past an arm 658 to restore the lever. Totalizers. The machine has four totalizers, Fig. 11, a totalizer " * " for accumulating all " Cash " and " Accounts Paid " items engaged when either of the keys 11, 12 is depressed, a totalizer C controlled by key 13 and receiving " Charge to Account " items, a totalizer A for " Paid Out " items selected by key 14, and an item-totalizer MP engaged during every operation in which the multiple-item key 15 is depressed. Totalizer-engaging mechanism ; total-taking. Each totalizer is adapted for counterclockwise rocking about a shaft 91, Fig. 11, for engagement with the actuators. To effect this rocking, a plate 101, Fig. 8, having three studs 102 ... 104 is pivoted to each transaction totalizer shaft 88 and is set relatively to the shaft under the control of the special keys and the operation control lever. One step of movement of a plate engages the stud 102 with a notch 105<a> in an engaging disc 105 rocked at each operation in " Add timing. Two or three steps of movement of the plate rock the studs 103, 104 respectively into engagement with notches on discs coaxial with disc 105 and rocked according to subtotal and total taking timing. The movement of the plate is derived from a shaft 68, Figs. 7 and 8, rocked at each operation by the release lever 58, the motion being transmitted for each totalizer through a link 76, lever 75, link 78, slotted lever 79, stud 82, link 83, lever 85 and link 86. This linkage is normally ineffective owing to the pivot 74 of the lever 75 being situated on a freely mounted lever 73. However, upon the depression of the appropriate transaction key (key 11 or 12 in Fig. 8), the lever 73 is locked by a stud 71 on a slide 70 and the linkage rendered operative. The adjustment of the operation control lever from " Add " position serves through a shaft 60, link 96 and link 83 to move the stud 82 away from the fulcrum 80 of the lever 79 to one of the positions 82<1>, 82<11> for subtotal and total taking, respectively. The movement of the plate 101 derived from shaft 6S is thus increased to engage the desired stud 103 or 104. The multiple-item totalizer MP, Fig. 11, is controlled only by the keys 15 and 16 ... 18 for adding and total-taking, respectively, its engaging plate 101<d> being provided with studs 103<d>, 104<d> in the second and third positions only. The lever 73d for the item-totalizer being fixed, the slotted lever 79<d> is rocked at every operation. However, as no stud is provided in the first position on the plate 101<d>, the movement is normally inoperative. Upon the depression of the multiple-item key 15, a slide 116 is lowered and through a bell-crank 115 rocks the stud 82d to the position 82<1> to cause the engagement of the stud 103d with the " Add " disc 105. Similarly, depression of one of the item-total keys 16 ... 18 rocks the stud 82<d> to the position 82<11> to cause the engagement of the stud 104<d> with the totaltaking disc. Zero-stop pawls. The zero-stop pawl 121, Fig. 12, of each amount bank is controlled in " Add operations by a stud 124 on the associated detent 125. The stop pawls are also controlled by arms 127 on a shaft 128 urged counterclockwise by a spring 133, but normally restrained by the engagement of an arm 129 with a high-spot on a cam 131. In an operation such as a total-taking operation, no amount key is depressed and the arms 127 disable the pawls. In an adding operation, however, the arms 127 are rendered ineffective by the abutment of one or more of them with flanges 134 on the detents. Keyboard ; second embodiment. In a second embodiment, Fig. 19, the special key bank of the machine comprises three clerks' keys 151 ... 153, a multiple-item key 154, an itemtotal key 155 and a " No Sale " key 156 . . . 158 for each clerk. The Specification as open to inspection under Sect. 91 comprises also :- Cash-drawer release. In the second embodiment of the machine shown in Fig. 19 and in Fig. 24 (Cancelled), the cash drawer is controlled in " No Sale " operations by a cam 178 set by the differential arm 172 of the special key bank. In a " No Sale operation, the cam raises a pitman 187 to release the latch 183. The usual mechanism is provided to release the drawer in single-item and item-total operations. Keyboard; item-total-taking ; third embodiment. In a third embodiment, Fig. 22 (Cancelled), the special key bank of the machine comprises two clerks' keys 151, 152 each controlling a totalizer V1, V2, a multiple-item key 154 controlling a totalizer MP, and a " No Sale " key 156. A grand totalizer H is engaged when either clerks' key is depressed. The items of a multiple-item transaction are entered only into the multiple-item. totalizer, no clerks' key being depressed at this time. An item-totaltaking operation is initiated by depressing the multiple-item key followed by the appropriate clerks' key, the total taken from the multipleitem totalizer being transferred to the selected clerks' totalizer and to the grand totalizer. For this purpose, a slide 163 corresponding to the slide 116, Fig. 11, is connected by a pin- and-slot coupling 168, 169 to a second slide 165 having cam-surfaces 166, 167 to co-operate with the studs on the clerks' keys. Upon the depression of the multiple-item key, the slides 163, 165 move downwardly one step thus positioning the surfaces 166, 167 beneath the key studs and shifting the stud 82d to the position 82<1> to condition the multiple-item totalizer for adding. Now upon the subsequent depression of a clerks' key, the detent 165 is moved a second step downward to shift the stud 82d to the position 82<11> and condition the multiple-item totalizer for total-taking. At the same time, the grand totalizer and the selected clerks' totalizer are conditioned for adding, i.e. to receive the total taken from the mutiple-item totalizer. This subject-matter does not appear in the Specification as accepted.
