Abstract: 1399661 Cash register or calculating machine programming ANKER-WERKE AG 26 April 1972 [26 April 1971] 19383/72 Headings G4T and G4B A cash register or calculating machine having a plurality of individual totalizers and a grand totalizer is arranged, upon depression of certain function keys, to operate automatically through a plurality of machine cycles, during each of which one of the individual totalizers is zeroized and the amount it held is transferred to the grand totalizer, so that before completion of the plurality of cycles an interim total of certain totalizers is printed and at the end of the automatically triggered plurality of cycles the individual totalizers are all zeroized and the grand totalizer holds the sum of the amounts they previously held which sum is printed. During each cycle, an assembly of six control discs 242-247 keyed to a shaft 223, Figs. 4 and 5, is stepped through one angular increment, the adjusted position determining operation of the machine during the next cycle. For this purpose, the peripheries of the control discs are formed with cut-outs, which are sensed by levers 248- 253. When the sensing end of a lever 248-253 enters a cut-out in the associated control disc, a stop arm 269, Fig. 5, of the lever moves clockwise to decrease the amount of anticlockwise rotation which an associated lever 274a, 275- 279 can make. These latter levers are linked to a differential mechanism 180, normally controlled by the function keys of the machine. This control is over-ridden by the abutment of the levers 274a, 275-279 with stops 269, so that in effect the automatic control is equivalent to the setting of different function keys for each machine cycle. During the first nine automatically initiated cycles, totals are transferred to the grand totalizer from nine of the eighteen totalizers with which the machine is provided. The interim total, i.e. the amount held by the grand totalizer is printed at this point. During the next nine cycles, totals are transferred from the remaining nine totalizers, after which the grand totalizer is zeroized, the amount it held (i.e. the total of all eighteen totalizers) being printed.  Stepping the control discs 242-247.-For each rotation of the machine main shaft 53, a cam 237 acting through follower 235 and link 232 oscillates a feed disc 230, rotatable about the shaft 223 and carrying a feed pawl 226, engageable with a ratched wheel 240 keyed to shaft 223. A locking pawl 228 prevents reverse rotation of the ratchet wheel. The pawls 226, 228 are normally held out of engagement with the ratchet wheel by pins 224, 225 carried by a lever 222. When keys (not shown) initiating the automatic series of cycles are depressed, a disc 201 (Fig. 5) is rotated to allow a pin 203 to fall into its recess 207 and thus, through linkage 206 212, to trip a latch 215 freeing the lever 222 to a spring 335. The consequent anti-clockwise rotation of the lever 222 renders pawls 226, 228 operative. The feed disc 230 is linked to a rod 295 controlling a latch 297 for an arm 301; each oscillation of the feed disc frees the arm 301 which trips a release mechanism (Fig. 6), automatically initiating the next machine cycle. Second embodiment, Figs. 7-11 (not shown). The ratchet wheel (341) is driven directly by a hooked arm (343) oscillated by a drive from the machine main shaft. The peripheries of the control discs (406, 420-422) are sensed directly by lugs (409, 425) on levers (412, 427) linked to differential release mechanisms associated with the banks of function keys. The hooked arm engages a flat (345) on the ratchet wheel initially and the first incremental step is imparted to a locking disc (352) by a linkage extending from the function key (16) initiating the automatic cycles. Means are provided for interrupting the series of automatic cycles (e.g. to enter new data) and then continuing the series.
