Abstract: 368,117. Registering accounts, &c. KRUPP AKT.-GES., F., Essen, Germany. April 15, 1931, No. 11153. Convention date, July 12, 1930. [Class 106 (i).] In a machine for registering transactions involving the calculation of new balances from previous balances and current entries, the selective coupling of the adding or subtracting side of the balance totalizer takes place automatically and directly on depression of the motor key, the selection being predetermined by the sign of the " old balance " key or itemcharacterizing key used, or of the balance to be taken. To register a complete transaction the old balance is set up on the amount keys 201, Fig. 1, an " old balance + " key 204 or " old balance -" key 205 depressed, and the motor key 144 operated whereupon the balance is entered on the + or - side of the balance totalizer and on the corresponding + or- " old balance " totalizer. Next, the new item is similarly set up and entered except that the paid-in or paid-out key 206 or 207 is now depressed to govern the sign of the entry and to cause the item to be registered in a corresponding totalizer. Moreover the item may also be entered in a transaction totalizer appertaining to a selected key in banks of transaction keys 232, 203. Finally, to take the new balance, the lever 121 is shifted to " balance " from " addition " and the motor key depressed, whereupon the balance totalizer is automatically conditioned to present its correct side for total-taking and the total taken is transmitted to an automatically selected credit or debit " new balance " totalizer corresponding with blank keys 115, 116. To take a total or sub-total from any of the trans. action totalizers, the total lever 38 is suitably positioned and the totalizer is selected by means of a setting-lever 208, 209, or 210. By shifting the lever 38 to a position marked " duplicate " a previously entered item may be again set up, printed and entered in the balance totalizer but without registration on any of the transaction totalizers. Balance totalizer. This occupies a line by itself and comprises for each denomination an adding wheel 1, Fig. 2, and a subtracting wheel 2 geared with wheel 1 for opposite rotation through pinion 4, connected gears 5, 8 and a broad pinion 10 mounted on an adjoining shaft and gearing with wheel 11 secured to the hub of wheel 2. The particular wheel 1, 2 to be driven is selected by the usual rider 14 carried by an axially adjustable shaft 13 and serving to convey the drive from the actuated pinion 16 and its elongated hub 195. Transfer-mechanism. This is similar to that described in Specification 345,029 but modified for the automatic addition of the " fugitive 1." Axial shifting of the rider shaft 13 is accompanied by equal movement of the parallel shaft 18 carrying the teeth 23 for displacement by the transfer teeth 1a (2a), Fig. 3. Axially immovable but rotatable on the shaft 18 is a series of pinions 25 each having a slotted hub for receiving the tooth 23, the displacements of which are transmitted to the pinion by a bar 24. Each pinion at its left-hand end, Fig. 2, has a lug 26 adapted to abut, after movement of 45‹ in one direction or the other, against a shoulder 27 formed on an eccentric hub 28 normally locked by a disc 30 fast on a shaft 20 given rotary movements in stages for unlocking, locking, and transfer-operating actions as described below. Thus if a numeral wheel passes from 9 to 0 its long tooth displaces the tooth la or 2a and therefore the pinion 25 through 45‹ to bring the lug and a shoulder into engagement and also to place the pinion within reach of a driving tooth 31a, Fig. 3, so that in the subsequent movement of the shaft 18 the pinion and therefore also the eccentric 28 are driven through 90‹, whereupon the transmission pinion 19 mounted on the eccentric, rolls on the now stationary transmission wheel 21 and thus advances the next higher numeral wheel through the pinion 16. The drive of the transfer-operating shaft 20 (formed in two lengths 20a, 20b) is obtained from a shaft 35, Fig. 9, given one revolution in each cycle and adapted to be coupled with a loose wheel 39 through a broad pinion 37 mounted on a lever 45 rocked by a cam 41 controlled by the total lever 38 so as to cause coupling in item-entering operations only. Driven from the loose wheel 39 is a wheel 48 rigid with an adjacent driving wheel 49 and looking disc 50 which actuate and lock wheel 52 in turn so as to cause the transfer-resetting shaft 51 to rotate first through 120‹ and then towards the end of the cycle through a further 60‹. On this shaft are fixed the mutilated pinions 53, Fig. 3, one set of teeth of which can thus return any pinions 25 displaced in the previous cycle. The transfer-operating shafts 20a, 20b are driven from the above wheel 39 by a special cascade arrangement of Geneva mechanism shown in Figs. 10 and 13. Fixed to the wheel 39 are actuating and locking discs 58, 59, 60 to drive a pinion 62 through two steps of 30‹ and a step of 300‹ with locking in between the successive steps. Secured to the pinion 62 are six further actuating and locking discs 63 : . 68 serving as regards the first three to drive a pinion 69 through steps of 30‹, 30‹, 150‹, and 150‹ while the other three step a pinion 70 through 30‹, 30‹, 360‹, and 300‹. The two pinions 69, 70 are respectively connected with the two shafts 20b, 20a, the pinion 70 driving the shaft 20a through the countershaft 54, Figs. 3, 4, and 21a, and pinions 74, 75. The shafts 20a, 20b carry groups of actuating and locking discs 30, 31, 32 for the transfer operations in the six lowest and three highest denominations respectively, the transfer operating teeth 31a being duplicated on their discs in the latter groups. The disc 32 locks the transfer restoring train between movements, the disc 30 similarly locks the eccentric 28, and the disc 31 is formed with a driving tooth (or in the case of the three highest denominations two driving teeth) and the necessary locking surfaces. In the normal position the disc 31 locks the transfer pinion 25 directly and the locking disc 32 locks it indirectly through the restoring pinion 55. When the transfer shaft is first stepped through 30‹, the pinions 25, 55 are released and shaft 51 turns through 150‹ to restore the transfer pinion if displaced. In the next 30‹ of movement the eccentric 28 is locked by disc 30 while the amount is entered. In the following 150‹ (or 360‹) of rotation transfer can take place by the tooth 31a driving pinion 25 through 90‹ whereupon the pinion is again locked. Exceeded capacity and change of sign of the balance totalizer. When the capacity is exceeded the transfer tooth of the highest denomination rocks the shaft 18, Fig. 22, and by a pin-and-slot a sleeve 80 formed with a lug 82 to co-operate with a shoulder 83 on the transfer pinion 25<1> in the lowest denomination. Connecting the sleeve and pinion is a helical spring 85 and the pinion gears at 84 with a toothed sector 88, Fig. 7, carrying a spring-controlled pawl 89 co-operating with a four-toothed ratchet wheel 91. On the hub of the latter are formed four lugs 92a, 92b, 93a, 93b, Fig. 8, disposed two and two in separate planes, the lugs in one plane being diametrically opposite each other and displaced 90‹ with respect to those in the other plane. Co-operating with the lugs is an arm 94 fixed to the rider shaft 13. If the machine is set for addition this arm will be situated in the plane of lugs 92a, 92b and for subtraction in the plane of the other two lugs. If therefore the totalizer contains a positive amount and by addition of an item the capacity is exceeded the passage of the transfer tooth belonging to the highest denomination causes sleeve 80, Fig. 22, to turn through 45‹ and since the arm 94 prevents movement of ratchet wheel 91 and therefore of pinion 25<1> this turning is merely absorbed by the spring. A similar action occurs if the totalizer has a negative total and its capacity is exceeded, the arm 94 in this case being in the plane of the other pair of lugs 93a, 93b. If however the sign of the amount on the totalizer changes the arm and its co-operating lug are separated by 90‹ so that the ratchet wheel and therefore the transfer pinion 25<1> are capable of the preparatory rotation through 45‹ with the result that it subsequently receives the further rotation of 90‹ to cause the addition of unity to the lowest denomination. Control of keys 115, 116 by balance totalizer. When the balance total changes its sign the rotation of ratchet wheel 91 effects through gearing 95, 96, Fig. 21a, the rotation through 60‹ of a cam 98 formed with a triangular groove 98a, Fig. 24. This groove controls through a lever 100 and the connections shown a slide 108 carrying two spring-controlled pawls 111, 112 slotted to engage pins on the blank key stems 115, 116. Pivoted at 118 is a lever 119 connected at 183 with lever 185 linked with the balance lever 121. The lever 119 also has a pin 122 bearing on an extension of one or other pawl 111, 112. If the balance totalizer contains a positive amount one of the two lugs 92a, 92b lies against the arm 94 and one of the angles of the cam groove 98a is therefore operative to maintain the slide 108 in its lower position with pawl 111 engaging key 115 while key 116 is free. If the amount on the totalizer changes to negative one of the other two lugs 93a, 93b comes against the arm 94 and the cam 98 is turned through 60‹ to raise the slide 108 to its upper position so that the negative key 116 is engaged. Taking the balance. For this operation the lever 121 is set to " balance " and consequently the lever 119, Fig. 24, is rocked clockwise to lower pawl 111 or 112 and thus depress the - or - key 115, 116, according to the sign of the balance, the key being then held down by the usual detent plate to select the corresponding totalizer in the ensuing operation. Connections with motor key 144. The six keys 20
