Abstract: 176,374. Krupp Akt.-Ges., F. March 7, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Cash registers; machines with several itemvalue totalizers.-Relates, to cash register machines of the key-set and independently-operated type with multiple totalizers and comprises means for putting the selected totalizer in action and for zeroizing any single totalizer or all simultaneously. Totalizing counters.-The differential sectors a<3> gear each with one of a pair of pinions a<12>, the other of which a<13> gears with a pinion b<1> on one of a set of nested sleeves carrying at the other end the totalizer-actuating pinions b<3>. At the appropriate time the pinions a<12>, a<13> are connected by long pinions on rocking levers in the usual way. The totalizers are carried on frames F, Fig. 3, rocking on pivots E in the ends d<1>, d<2> of a drum D, with reading apertures, and are put into gear with the pinions b<3> by engagement of the frame F with a slide g<1>. Fig. 4, mounted in a disc G set selectively from the keyboard. This mounting avoids inertia effects in the ordinary actuation of the totalizers, the whole drum D needing only to be rotated for reading a total or zeroizing a single totalizer. Zeroizing-mechanism.-To zeroize a single counter a detachable key is passed through the corresponding hole b<6> in a disc B<5>. Fig. 1, fast on the shaft B to which the drum D is secured. The shaft and drum are then swung round till the key abuts against a stop c<3> on the casing, bringing the key in line with a key hole c<2> in the casing through which the key is then passed to engage a slot in the end of the pivot E of a counter frame, the inner end of which pivot is slotted to engage the correspondingly shaped end of the spindle of the next counter. The spindles are grooved in the usual wav. A spring pawl d<6>, Fig. 1, engaging a ratchet disc on the pin E acts as a stop. For zeroizing all the counters simultaneously the pins E have pinions e<4> gearing with a central portion b<7> which can be operated by a pinion h' fast on a pin H journaled on the drum wall and adapted to be engaged by a key inserted through a keyhole c<4> in the casing and a keyhole b<8> in the disc B<5>. In the normal position of the drum the hole b<8> is axially opposite the hole c<4>, while a solid portion of the disc B<5> is opposite the keyhole c<2> as shown in Fig. 4. Interlocking.-The zeroizing mechanism is controlled by two locks J, K, Fig. 4, turned by removable keys, the locks having gapped discs to lock either if the other is operated. To zeroize a single counter, the lock J is rotated by its key, thereby rocking a plate J<4>, Fig. 8, to clear a notch in the drum wall d<1> allowing the drum to be rotated as described above. A nose i<12> on the plate J<4> engages a projection i<11> on a slide J<7> having a slot to engage a pin on a lever M which locks the keyboard by means of a link m<3> during zeroizing. To zeroize all totalizers simultaneously the keyhole c<4> must first be uncovered by a sliding plate K<4>, Fig. 9, which is pin-and-slot geared to the lock K. To permit of either single or all together zeroizing of the totalizers the slides J<7> and K<4> must be freed from a locking arm n<1>, which is effected by a special operation of the machine, in which no item is set, but which ungears any totalizer from the pinion b<3> and places the disc G with the slide g<1> in inactive position, at the same time causing a cam g<2> on the disc to rock the arms n<2>, n<1> to free the slides K<4> and J<7>,
