Abstract: 465,402. Calculating - apparatus. KOOPERATIVA FORBUNDET FORENING, U.P.A. Aug. 2, 1935, Nos. 21966 and 21967. Convention dates, Aug. 4, 1934 and Oct. 4, 1934. [Class 106 (i)] In a cash register or like calculating-machine in which an old balance standing on a total retainer is communicated to a totalizer at the beginning of an operation and in which a new balance formed in the totalizer during the operation is communicated back to the retainer, a number of retainers is mounted for rotation as a unit about a central axis whereby a desired retainer may be selected, means being provided to displace the unit bodily to bring the selected retainer into engagement with mechanism for communicating the old balance standing thereon to a totalizer common to all the retainers of the unit. First embodiment. In the form of the invention shown in Fig. 1, the total retainers each comprise a number of racks 4 mounted in parallel alignment and slidable radially on discs 16 rigid with a shaft 18<1>, racks of the same denomination being mounted on the same disc. The shaft 18<1> is carried by a slide 17 and, in normal position, a pinion 18 on the shaft meshes with a manually adjustable rack 2 whereby the racks of any desired retainer may be brought into alignment with a corresponding number of transmitting racks 3. During the first part of a machine operation, the shaft 18<1> is raised and the racks of the selected retainer, which are locked at this time by a bail 5, adjust the transmitting racks and totalizer pinions 7 engaged therewith, from zero position, to positions corresponding to the old balance standing on the retainer. The totalizer pinions are now locked and shifted to the left into mesh with actuator racks 1 which have been displaced upwardly in accordance with the item set up on amount keys N. After the totalizer pinions and retainer racks have been freed, the actuators are returned downwardly to zero position to add the item into the totalizer, which is provided with transfer mechanism of unspecified type. The retainer racks are constrained to follow the movements of the totalizer wheels, during this part of the operation, by the engagement of lugs 12 on the transmitting racks with snail cams 8 rigid with the totalizer pinions, springs 6 acting on the transmitting racks being strong enough to overcome springs 14 acting on the retainer racks. Finally, the totalizer is returned into mesh with the transmitting racks ; the retainer racks, now holding the new balance, are locked; the shaft 18<1> carrying the retainers is lowered to normal position and the transmitting racks and totalizer pinions are restored to zero by the springs 6. Multiple-item transactions. The items of a multiple-item transaction are accumulated on a totalizer 15 engaged by the main totalizer 7 when the latter is in its left-hand position. The totalizer 7 is returned to the right after the entry of each item but the selected retainer is maintained in engagement with the transmitting racks 3. Indicating and printing arrangements. Denominational racks 9 connected by pinions 21 to item printing and indicating devices are normally held in upper position by springs, but are coupled by wide pinions 10 to the actuators during the downward restoring movements of the latter. The balances standing on the retainers are communicated to printing and indicating mechanisms by pinions 20 meshing with the transmitting racks 3, while means may be provided for printing a multiple-item total accumulated in totalizer 15. Second embodiment. In the form of the invention shown in Fig. 2, each retainer comprises a series of toothed wheels mounted in axial alignment on discs 16 rotatable as a unit with a central shaft 26 to bring a selected retainer opposite to the transmitting racks 3. The shaft 26 is carried by a lever 39 rockable by cams on a shaft 37 to engage and disengage the selected retainer with the racks 3 at the beginning and end of each operation, respectively. The racks 3 co-operate at their upper ends with totalizer pinions 7 and snail cams 8 as in the first embodiment described. Each denominational unit of a retainer comprises a pair of wheels 4, 22, Figs. 4 .... 9, freely mounted on a stud extending laterally from the associated disc 16. The wheel 4 is adapted to mesh with the transmitting rack 3 and is provided with an offset dog K4 that assumes the constant position shown in Fig. 5 at the end of each machine operation. The second wheel 22 is adapted to be coupled to the first wheel 4 by a pinion 25 moved to and from coupling position by cams on the shaft 37. This second wheel is provided with an offset dog K22 having the same circle of movement as the dog K4 and spaced therefrom by an angle commensurate with the denominal digit of the balance standing on the retainer. Means are provided to give the second wheel 22 constant clockwise and counter-clockwise excursions of nine steps during each operation, such means comprising a toothed sector 27 rockable about the shaft 26 by cams 28, 29 and coupled to the second wheel by a pinion 31 moved to and from coupling position by cams on the shaft 37. At the beginning of an operation, the selected retainer is rocked to the left into engagement with the actuators and the pinions 31 are rendered effective to couple the wheels 22 to the driving sectors 27. The wheels 22 are now rotated clockwise through nine steps from the position shown in-Fig. 5 to that shown in Fig. 6, whereby, after idle movements, the pairs of dogs K22, K4 abut and the old balance is transferred from the retainer to the transmitting racks 3 and totalizer wheels 7. The sectors 27 immediately return, causing the wheels 22 to rotate counter-clockwise through nine steps to the position shown in Fig. 7, wherein the dog K22 abuts the other side of the dog K4, the wheel 4 having remained stationary. During the entry of the item, the wheels 4, 22 are coupled by the pinions 25 and the pinion 31 uncoupled, with the result that the wheels move together to some new position, Fig. 8. At the end of the operation, the wheels are uncoupled, the wheels 22 locked, and the wheels 4 returned counterclockwise to zero position as the transmitting racks and totalizer pinions return to their zero positions. The angular distances between the pairs of studs K4, K22 are now commensurate with the digits of the new balance. Finally the retainer unit is shifted to the right to disengage the selected retainer. Clerk's and transaction retainers. In order that an item may be entered simultaneously into a clerk's retainer and into a transaction retainer, the machine is provided with two retainer units, the denominational wheels of which are mounted on interspersed discs 16A, 16B, Fig. 4. The discs of each unit are rotatable together, but independently of the discs of the other unit to select a desired retainer in each unit. A totalizer 7A, 7B, Fig. 3, and set of transmitting racks 3A., 3B is associated with each retainer unit, totalizer pinions of the same denomination being adapted to mesh with racks 11A, 11B, rigid with a single actuator 1. Multiple-item transactions. One retainer in each unit serves as a multiple-item totalizer for the other unit, being selected for the whole series of operations of a multiple-item transaction irrespective of which retainer or retainers in the latter unit may be selected. To print the multiple-item total, pairs of wheels 42, 45 meshing with the transmitting racks 3A, 3B are selectably coupled by pinions 44, 46 to wheels 43, that are mounted between each pair of wheels 42, 45 and connected to printing mechanism, the wheels 43 or 45 of the unit containing the multiple-item totalizer being selected for connection to the printing mechanism. Taking totals from the retainers. Totals taken from the retainers of one unit are transferred by coupling pinions 50 from the totalizer of the unit to the totalizer of the other unit to form a grand total. This grand total is printed through the means described above for multipleitem totals.
