Abstract: 389,093. Cash registers &c. KRUPP AKT.-GES., F., Essen, Germany. Sept. 7,1931, No. 25109. Convention date, Sept. 15, 1930. [Class 106 (i).] The machine is provided with a number of transaction totalizers and an accumulator and the setting and coupling arrangements are such that every item entered in the transaction totalizers is also entered in the accumulator and the zeroizing of any of the transaction totalizers is always accompanied by transfer of the total to the accumulator, thus permitting of the formation of two grand totals for mutual checking purposes. In the machine described a main totalizer as well as an accumulator is provided and the engagement of the various totalizers is so controlled that the total on the accumulator when zeroized is transferred to the main totalizer and the totals on the transaction totalizers when zeroized are transferred to the accumulator. Thus the two grand totals required are formed, one in the main totalizer and the other in the accumulator. Another accumulator is also provided for aggregating supplementary items not to be entered in the other totalizers. General arrangement. In addition to the amount keys 10, Fig. 1, there are three banks of transaction keys 11, two motor keys M1, M2, total-selecting levers 1, 2, 3 and total-taking control levers 4, 5. The first position in the third bank of transaction keys corresponds with the main totalizer and possesses only a blank key. Control of motor-keys by operation-control lever 5. This may be set for supplementary entries, ordinary item-entering, sub-totals and totals and through gearing 13, 15, Fig. 2, positions a cam disc 16 accordingly so as to control a pair of bell-cranks 18, 20 furnished with stops 18a, 20a co-operating with stops 22a, 23a, 23b on spring-controlled levers 22, 23 engaging pins on the motor keys M1, M2 When the lever 5 is positioned for supplementary entries or for addition, both motor keys are free. If the lever is at subtotal (reading-off) key M2 is locked and if at total (zeroizing) both keys are locked. Moreover, if the lever 5 is placed at " setting-off " a cam disc 35, Fig. 10, is thereby set so as to displace a detent 40 to lock M1 and free M2. If the lever is at addition M1 is free and M2 locked, and if at reading-off or zeroizing both keys are free, i.e. so far as the detent is concerned. Control of motor keys by total-selecting lever 3. This lever is geared with another cam disc 29, Fig. 2, exercising an over-riding control over bell crank 20, the end of which co-operates with both discs 16, 29. If, with lever 5 at zeroizing, lever 3 is set for adding or for taking a total from any of its transaction totalizers, the bell crank 20 is rocked to free motor key M1 but if lever 3 is placed for taking a main total key M1 is locked. The lever 3, however, also controls, through a lug 32a, the bell crank 18 with the result that in the position last stated motor key M2 is freed. Control of motor keys by control lever 4. This lever is capable of three positions, viz. addition, zeroizing the first or multiple-item accumulator denoted S<1> (but not shown), and zeroizing the second or supplementary accumulator S<2> (also not shown) and by mechanism similar to that shown in Fig. 10 it determines whether and which of the motor keys shall be locked. Control of blank key (for selecting the main totalizer). This control is exercised by levers 4, 5 in combination and for this purpose the levers are connected through a differential gear with a cam 49, Fig. 8, determining by means of a pitman 51, lever 54, link 55 and arm 56a the effectiveness or otherwise of the blank key 58. If lever 5 is set for addition and lever 4 for zeroizing the first accumulator S<1> the key is depressed to select the main totalizer for actuation. Selection of the accumulators by'lever 5 and the keys M1, M2. Depression of either key acting in one direction or the other through a slide 59, Fig. 12, and gearing 62, 63 and one member of a differential gear sets a cam drum 76 (not shown) controlling the situation of the usual rider axle with respect to the pinions of the two accumulators. Another member of the differential gear is connected with the lever 5 so that the accumulator selection depends upon the position of this lever in co-operation with which of the two motor keys is depressed. Operations. (1) For ordinary item-entering levers 4, 5 stand at addition and levers 1, 2, 3 at normal. so that key M1 is free and key M2 is locked. By depression of key M1 the cam drum 76 effects the selection of accumulator S<1>, so that the items are totalized in this as well as being entered in key-selected transaction totalizers. (2) When it is desired to take the total of a number of such entries from this accumulator, lever 4 is set accordingly and the only free key M1 is depressed. Accumulator S1 is still selected but owing to the different setting of lever 4 the blank key 58 is now effective so that the amount taken from the accumulator is entered in the main totalizer. (3) For supplementary entries lever 4 is placed at:addition and lever 5 at "setting off." Only motor key M2 may now be depressed with the result that through cam drum 76 accumulator S2 is selected for actuation ; moreover, due to lever no transaction totalizer is selected, although a transaction key may have been set to characterize the item. (4) To read a subtotal from a transaction totalizer, lever 5 is correspondingly set and the totalizer selected while lever 4 stands at addition. Consequently key M1 only can be used and due to lever 5 and the depression of this key cam drum 76 turns to put both accumulators out of action. A similar condition exists for reading the main totalizer, the shifting of lever 3 to the lowest setting having no effect upon the key M1 owing to the cam disc 16 over-riding cam disc 29. (5) To zeroize the transaction totalizers the relevant setting of lever 5 locks key M2, and through cam drum 76 selects the accumulator S1 so that the total is taken from the selected transaction totalizer and transferred to the accumulator when key M1 is depressed Each transaction totalizer having been thus treated, the accumulator may be zeroized and its total printed, the levers 4, 5 being set accordingly so that the total is not transferred to the main totalizer. (6) If the main totalizer is to be zeroized, levers 3, 4, 5 are set and key M2 is freed by the action of lug 32a, Fig. 2, and depression of this key prevents actuation of either accumulator. (7) For zeroizing accumulator S2 levers 4, 5 are set and key M2 only is then free and when depressed causes the selection of the accumulator. It will be seen from (5) and (6) above that a first grand total may be printed by operation (6) and that by effecting operation (5) the various transaction totals may be printed followed by a printing of the second grand total then standing on the accumulator S1, the two grand totals being of course identical. If desired the main totalizer need not be used, all items being entered and accumulated on S1 so that this furnishes the grand total. By clearing this and then zeroizing the transaction totalizers the same total may be attained on S1 again. In a further method of operation the main totalizer is first cleared of its grand total and then the totals on the transaction totalizers are transferred to S1 and then by operation (2) above the second grand total thus formed is transferred from S1 to the main totalizer.
