Abstract: 365,164. Calculating - apparatus. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Anker-Werke Akt.-Ges.; Bielefeld, Germany.) Oct. 16, 1930, No. 30983. [Class 106 (i).] Account-storing apparatus.-A large number of individual accounts mav be entered in the machine and stored upon sets of horizontal racks, disposed in banks one above another. In the form shown there are five such banks each containing nine sets of racks, these being grouped by denominations and capable of selection to co-operate with the differential actuating mechanism. The amounts are set up by means of keys 119a, Fig. 2, and are transmitted by differential-mechanism 118 to racks 21, Fig. 1, engaged, under the timing control of the machine, by pinions 14 mounted, together with known transfer-mechanism 25, on a transverse bar 26 movable towards and from the racks 21 by cams 126 on a rod 46, Figs. 8 and 8a. The account racks 4 are slidably supported on a stationary bar 1, Fig. 1, and are toothed at 8 to lock normally with a rib 11 on a frame member 10. The racks are also toothed at 9 to engage elongated pinions 13 rigid with the pinions 14 and are adapted to be pushed forward by arms 30 fast on a shaft 29 forming together with rod 46 part of a selecting carriage 31, there being one such arm 30 for each denominational group of racks. The timing of engagement of the racks with the actuators is controlled by three cams of which only one, 99, is shown. According to the setting of a control lever, a shaft 87 is turned to place an arm 88, 89, or 90 in front of a corresponding pin 86 to cause an arm 83 to embrace a stud 91 on a cam-operated lever 93. Thus by the setting, only a selected one of the cams becomes effective to rock an arm 79 and thus raise and lower (with different timings) lugs 75, 76, embracing vertically slidable plates 69 controlling the positions of the racks 4. Operation ; selecting the account racks. One or more of five setting levers 56a .. e, Fig. 6, is turned to rotate a cam segment 50 and so slide the rod 46 and carriage 31 to bring the arms 30 in rear of the desired rack in each denomination. Entering new item. The racks having been selected and the stem set up the machine is operated. The cam 99 and lever 93 then lower the plate 69 to engage the racks with the pinions 13, and the cams on the rod 46 swing levers 125, Fig. 8a, to cause arms 123 to embrace pins 120 on the bar 26. The machine acting by means of one of a pair of slidable side-byside cams 147, 148, Figs. 12 and 12a, now raises a rack 39 to rotate the shaft 29 so that the arms 30 thrust the selected racks 4 forward to the limit as determined by the pin 7 and slot 6 and so transfer their stored amounts to the pinions 14. The cam 141 then acting through the linked bell cranks 132, 133 and bar 129 thrusts the bar 26 forward to engage the pinions 14 with the racks 21 to receive from them the additional item as determined by the amount keys and the differential mechanism. Any transfers necessitated by the additions are then effected and the pinions 14 disengaged. Finally the pinions are restored to zero position by the ascent of a rack bar 18 co-operating with mutilated teeth on the pinions so as to transfer the new amount to the racks 4 which are then raised from engagement with the pinions and locked against the rib 11. Total or sub-total taking. The amount standing on the selected racks is transferred to the pinions 14 when these are in gear with the actuating racks so that these may convey the amount through the sectors 172 and nested sleeves 66 to the type-wheels. The variations in the timing of the engagement of the racks 4 with the pinions 14 are produced by the selection of one or other of the cams such as 99 as already described. The variations in the timing as regards the advance of the racks by the arms 30 are provided for by the axial displacement of the cams 147, 148, Fig. 12a, so as to substitute cam 148 for reciprocating the rack 39.
