Abstract: 432,316. Cash registers. HARTRIDGE, O. C., 118, Holborn, London, and ELLER, F., 23, Waltharistrasse, Wannsee, Berlin. June 5, 1934, No. 16713. [Class 106 (i)] A differentially-set cash register having adding mechanism actuated by finger-operated setting-discs and printing mechanism, is provided with locking mechanism to prevent setting movement of the discs during a whole disc-restoring operation and for permitting such setting movement only after the discs have been restored. Sequence arrangements and interlocks. The amount and transaction are set up by the differential adjustment of finger discs 1, Fig. 1, each geared to an indicator-drum 52 and carrying type 4. At the beginning of an operation, an operating-lever 15 is oscillated to restore the discs set during the previous operation and enter the amount into a totalizer 119. The new amount is set up and printed on a record strip and issued-voucher upon the rotation of a handle 6. This sequence of operation is compelled by interlocks. The downward movement of the operating-lever 15 rotates a gear 17 and bail 38 clockwise about a shaft 53 to restore the setting discs. At the same time a segment 18 meshing with gear 17 is rocked counterclockwise and by means of an abutment 20 rocks a lever 11 clockwise about its pivot 22. The lower end of lever 11 is thus rocked clear of a high spot on a disc 12 that is flexibly mounted on the printing shaft 120 and, upon release, rocks clockwise to interpose the high-spot to the right of the lever 11 and thus prevent its return. The rocking of the lever 11 also serves through a horizontal link 26 to disable pawls 28, Figs. 1 and 5, that co-operate with notches in the setting-discs normally to prevent setting movements of the discs. Pawls 3, which serve to prevent restoring movements of the discs, are disabled, while the operating-handle is out of normal position, by means of a bail 33 operated by a notched disc 29 rigid with the gear 17. These pawls 3 are each flexibly connected to a pawl 36 that becomes effective while its associated pawl 3 is disabled. Upon the restoration of the operating lever, the setting discs are freed for forward movement and the lever is locked by a latch 13 urged counterclockwise by a spring-plunger 14 into engagement with a notch 43 in a disc carried by the lever. After the new amount has been set up, the handle 6 is rotated to print a voucher. The first part of the rotation removes the high spot on disc 12 from contact with lever 11 and permits the latter to return, thus re-engaging the pawls 28 and locking the setting discs until after the next rocking of the operating lever. At the end of its rotation, the handle is checked by engagement of the high spot with lever 11. Printing totals.-The totalizer comprises a number of type-wheels 61, Fig. 3, mounted on a shaft 86 and connected by idlers 60 to gears 56, Fig. 1, on the shaft 53. These gears 56 are each rigid with a ratchet wheel 55 and are advanced by pawls 54 on the setting-discs 1 upon the restoration of the latter. Studs 59 on the setting-discs, at zero position, abut tails 58 of non-return pawls 57 to prevent overthrow. The total is printed on an inserted slip 85, Fig. 3, by depressing a handle 83 and thus rocking a platen 82 against the type-wheels. Consecutive-numbering and date wheels are also mounted on the shaft 86, the former being advanced by pawls 87 actuated by a cam 90 on a shaft 78 geared to the printing-shaft 120. The totalizer is rockable about the shaft 120 to disengage gears 56, 60 in credit transactions. The totalizer is normally held in engagement by a latch 121 on the framework, but is freed by the tripping of the latch by a stud 123 on the transaction disc upon the adjustment of the latter to credit position. Transfer mechanism.-Each totalizer wheel 61, Fig. 3, is formed rigid with a ratchet wheel and with a disc carrying a transfer tooth 65. At transfer, the tooth 65 associated with the wheel of lower order cams a segment 67 counterclockwise, where it is held by the engagement of a detent 69 within a recess 71. This movement of the segment serves to retract a transfer pawl 75 that co-operates with the ratchet associated with the wheel of next higher order and is carried by an arm 74 connected to the segment by a pinion 73. Now upon the rotation of the printing-handle 6, cams 77 on shaft 78 operate in succession to restore the rocked segments and thus return the pawls 74 to effect transfer. Printing - mechanism ; voucher - issuing.- The record strip 44, Fig. 1, passes from a supply roll 101 to a storage roll 47, while the voucher strip 10 is fed from a roll 100 and severed by a knife 128, the strips being impressed simultaneously by a hammer 8 against the type 4 on the setting-discs. The hammer and recordstrip feed are operated by a cam 7 geared to the printing-shaft 120 rotated by the crank 6, while consecutive numbering wheels are advanced by a cam 921 on the shaft 120. To differentiate credit items from normal cash transactions, the former are column-spaced to the left as shown in Fig. 10. For this purpose, the record and voucher strips and the ink-ribbon 9 are supported by a carriage 102 mounted for lateral displacement on rollers 103. Upon the adjustment of the transaction setting-disc to credit position, a pawl 109 thereon rocks a latch 110, 105 to release the carriage to the action of a spring which moves it to credit-printing position and operates a bell or other alarm. The carriage is returned upon the next oscillation of the restoring-lever 15 by a bell-crank 117 connected by a link 116 to an arm 115 of the shaft 19. The voucher strip is fed for linespacing by a cylindrical segment 130, Figs. 11 and 14, rigid with the printing-shaft 120, and is issued by a segment 132 carrying an electro after the items have been printed. The segment 132 is free on the shaft 120 and normally held inoperative by a stud 137. However, upon the retraction of a catch 140 on the printing handle 6, a rod 135 is released to permit the segment to move under the action of a spring 133 into operative connection with studs 134 projecting from segment 130. The severing- knife 128, Fig. 1, is operated by a hand lever but is disabled until the end of an operation involving the rotation of the ejecting segment 132 by means including a lever 142, Fig. 14, co-operating with a conical part 141 of the rod 135.
