Abstract: 296,002. National Cash Register Co., (Assignees of Shipley, B. M.). Aug. 22, 1927, [Convention date]. Cash registers with several totalizers.-A cash register or accounting-machine, having a plurality of totalizers arranged in groups, is provided with means whereby a total may be automatically transferred from any totalizer in any group to any totalizer in another group or groups. The invention is described as applied to a machine of the Shipley type described in Specifications 8119/15 and 176,781. Group totalizers 1GT, 3GT, Fig. 1, are provided in the zero positions in the upper and front lines, respectively, that :n the upper line being associated with the individual totalizers in the front and back lines, and that in the front line with the individual totalizers in the upper line. Totalizer-engaging mechanism. During an adding operation, selected totalizer lines are moved into engagement with the actuators by means of an adding engaging plate 200, Figs. 9 and 14, that is rocked from the main shaft 30 through cams, lever 203 and link 201. Rods 198, connected to the totalizer shafts 184 by links 197 and cranks are moved, when selected, into operative engagement with off-set forks 199 on the plate 200. Totalizer-engaging control mechanism. The means for automatically selecting the totalizer lines to be moved into engagement with the actuators comprise three plates 210 - - 212, Fig. 1, rotatably mounted on a shaft 104, Fig. 14, and each differentially set by a control bank. The peripheries of the plates are formed with raised parts and are adapted to be engaged by three pins 213 each associated with a totalizer line. The pins are carried by levers 214 pivoted at 215 to a statonary plate 216, and are normally held out of engagement with the plates by radial arms 218 controlled by cams on the main shaft 30. A slot 230 in each lever 214 engages one of the rods 198 and positions it with respect to the corresponding fork 199 of the plate 200. Total, sub-total and total transfer mechanism. In total, sub-total and total transfer operations the totalizer line selected by the total lever is moved into engagement with the actuators by means operated by the main shaft but independent of the adding engaging plate. In a total transfer operation the amount is transferred to a totalizer in another line or lines selected by the depressed key or keys. If no key is depressed one of the group totalizers is automatically selected. The total lever 45 is provided with three cam slots 320, Fig. 14, that co-operate with the pins 213, so that in all total and sub-total positions of the lever 45, one of the levers 214 is rocked outwardly to move the corresponding rod 198 past the fork 199 and into a slot 324 in a resetting engaging plate 317. At the same time a rod 313, that is connected to the usual shaft 310 for controlling the mechanism for stopping the differential actuators under the control of the pinions, is rocked by the lever 214 into a slot 523 in the plate 317. The plate 317 is rocked from the main shaft 30 through the lever 203, Fig. 11, and link 352, the latter being provided with an offset arm 350 having notches 348, 349 adapted to engage pins 346, 347 on the plate. The end of the link 352 remote from the lever 203 is slotted to receive a roller 355 on a lever 356 pivoted at 357. The movement of the lever 356 is derived from the usual shaft 286, rocked by the total-taking mechanism, the shaft being connected to a pin 371 that engages a curved slot 373 in the lever 356 and a straight slot 370 in a lever 363, Fig. 9. During total-taking operations the arm 350, owing to the shape of the slot 373, is rocked downwardly at the end of the first cycle. The notch 349 engages the pin 347, and the plate is given a clockwise rotation to effect the engagement of the selected totalizer. The plate is returned at the first half of the second cycle and the notch lifted out of engagement with the pin. During sub-total operations, the lever 363 is rocked by the usual slot 365 in the total lever 45 to disconnect the plate 200. The resultant repositioning of the slot 370 in the lever 363 causes the notch 348 to engage the pin 346 so that the plate 317 is rocked during the first cycle. Towards the end of the first cycle, the notch disengages the pin, thus leaving the plate in rocked position until the end of the second cycle when the notch re-engages and the plate is returned to its normal position. The plate is locked in its two positions by a bellcrank lever 377 controlled by a cam-slot 380 in the lever 356 and engaging alternative notches 376, 381 in the plate. Printing. The usual zero-elimination mechanism is utilized to set the symbols " 1GT " and " 3GT," representing the group totalizers on the printing wheels, in printing position, the mechanism being controlled by cam plates set by the total lever. Specifications 8120/15, 100,569, 190,433, 191,346, 191,350, 192,083, 194,291, 199,046 and 215,010 also are referred to.
