Abstract: 628,064. Accounting-machines. NATIONAL CASH REGISTER CO. July 1, 1947, No. 17316. Convention date, Sept. 25, 1941. [Class 106 (i)] In a machine having several lines of totalizers, each line is controlled for engagement by a disc, the discs being set by totalizerselecting keys to cause the line containing a selected totalizer to be engaged with the actuators, automatically-operated means being provided which, during total-taking give an additional setting to the discs so that the total taken from a selected totalizer on one line may be transmitted to a predetermined totalizer or totalizers on another line, or on other lines, respectively. The invention is shown applied to a machine of the Shipley type disclosed in Specifications 8119/15, 176,781, 209,408, 255,076, [all in Class 106 (i)], and 503,626. Differential-acting mechanism. A main camshaft 130, Fig. 2, through levers and links rocks first clockwise a driving plate 119 which carries along with it a latch 113 pivoted on an arm 115 and having a pin 112 passing through slots 111, 116 in an actuating segment 104 and a plate 117, whereby the segment and plate are also carried along with the driving plate. When a beak 103 on the segment 104 is arrested by the stem of a depressed numeral key 54, the pin 112 is driven along the now stationary slot 111, the latch 113 thus being rocked free of the driving plate 119. During the return movement counterclockwise of the driving plate, a stud 142 thereon picks up the arm 115 and carries it and the latch 113 and segment 104 back to the initial position, the totalizers 139-141 being at this time engaged with the segments 104 to enter the item additively. Transmitting values to the printing mechanism. A beam link 145, Fig. 2, is pivoted to the latch-carrying arm 115 which moves differentially with the actuating segment 104, the link having a slot embracing a pin 146 on a link 147 connected at its upper end to an aligning sector 148 and at its lower end to a toothed sector 153 which drives any desired number of sets of type wheels 158 through known transmission gears 156. The beam link 145 is pushed by a roller 163 on the lever which operates the driving plate 119 until the edge of the beam link bears against a shaft 105. The slotted end of the beam link will then have positioned the link 147 in accordance with the setting of the arm 115 and thus of the actuating segment 104. Totalizer-selecting mechanism. The totalizers are of the interspersed type arranged in four lines 138 ... 141, Fig. 2, each line containing ten totalizers. Each line is provided with a corresponding bank of nine selecting keys which control differential mechanism similar to the amount-differential mechanism described above. A selecting link similar to the link 147, Fig. 2, is similarly positioned in accordance with the selecting key depressed. The lower end of the selecting link rocks a sector 223, Fig. 5, which rotates a drum cam 230 to shift a roller 232 .on the selecting slide 233 which slides the totalizer frame 242 along a totalizer-frame shaft 243 to align the pinions 138 of the selected totalizer with the actuators 104. The selecting slide 233 slides on a yoke 234 which is later given a small longitudinal movement to move the totalizer pinions from engagement with the actuators 104 into engagement with the transfer segments 170 as described in Specification 628,063. ..Totalizer-engaging mechanism for addition. Totalizer engagement is controlled by four coaxial selecting discs, one for each line, acting in conjunction with a single coaxial totaltaking control disc 263, Fig. 27. The control disc 259 for line 1 is shown in Fig. 26. The , nine selecting keys 55-63, Fig. 22, controlling, e.g., line 1 determine the differential setting of an arm 264, Fig. 14, linked to a bell-crank 266 having a slot engaging a pin 268 fixed to an arm 269, the pin also engaging a slot 274, Fig. 26, in the line 1 control disc 259 so that this disc is set in accordance with the selecting key depressed. A pair of feeler bars 280, 281, Figs. 17, 26, 27, for line 1 is then advanced towards the discs, the second bar 281 cooperating with the total-control disc 263 only. The feeler bars are mounted on a system of bails so arranged that, if both bars contact a projection 308, 307 on e.g., the line 1 control disc 259 and the total disc 263, an arm 309, Fig. 17, is rocked clockwise to lift a pin 310 into. a hook 348, Fig. 12, which is at this time above the pin, the hook being carried on an engaging spider 326 oscillated in adding timing by cams 339 on the main cam-shaft 130. The pin 310 is on a link 311 which is thus connected to the spider 326 to rock a lever 312 linked to an arm 315 on the No. 1 totalizer-line shaft 243. The lower end of the arm 315 has a roller 316 riding in a fixed cam track 317 so that, as the arm 315 is rocked, the totalizer shaft is moved to and from engaging position in adding timing. The feeler-bar system is disabled when a pin 289, Figs. 14, 17, is moved to the widened part of a pair of slots arranged as shown. The pin 289 is on a link 290 pivoted to a lever 291 urged clockwise by a spring into disabling position, but prevented from moving into this position by a pin 294 on a spider 295. The spider is rocked counterclockwise but, in adding operations, disabling movement of the lever 291 is inhibited by the contact of a stud 303 on the lever with a step in a slot 302, Fig. 27, in the total control disc 263 which during adding stays in the initial position as shown. The total of all items entered into any of totalizers 1 ... 9 of line 1 is registered in totalizer 0 of line 2. To this end, the line 1 control disc 259 has 9 projections 352, a corresponding one of which is brought opposite one of the feeler bars 353 controlling line 2. The other line 2 feeler 354 is during adding obstructed by a projection 355 on the total control disc 263, so that the line 2 feeler mechanism is rocked to select this line for addition and, since no totalizer-selecting key is depressed, the 0 totalizer is in operative position. Similarly, the total of all items registered on totalizers 1 ... 9 of lines 2 and 3 is accumulated in the 0 totalizer on line 1 and the total of items entered into totalizer 1 ... 4 of line 4 is registered in totalizer 0 of line 3. Total taking. The main cam-shaft is driven through two cycles during total and subtotal taking. Movement of the total lever 95, Figs. 1, 22, to read (sub-total) or reset (total) position gives a small clockwise movement to a total-control shaft 347 to clutch a cam 375 to a gear 376 given one rotation during the two cycles of total taking. The cam 375 towards the end of the first cycle rocks the total-control shaft 347 a further distance clockwise, an arm 346, Fig. 12, on the shaft then operating mechanism which disconnects the engaging spider 326 from its add-timing driving cams 339 and connects it to other mainshaft cams which move the said spider in totaltaking timing so that the totalizer line coupled to the spider by an engaging link (e.g. the link 311 for line 1) is engaged to take a total from the totalizer selected on that line. The line from which a total is to be taken is determined by depressing one of four line-selecting keys 91 ... 94, Fig. 22, and the totalizer in that line is selected by depressing the corresponding selecting key 55 ... 81. If no selecting key 55 ... 81 is depressed, the total is taken from the 0 totalizer in the chosen line. The lineselecting keys 91 ... 94 differentially position the total-taking control disc 263, Fig. 27, through means similar to that whereby the line-control discs 259-262 are positioned by the selecting keys 55 ... 81. Assuming line 1 selecting key 91 and one of the keys 55 ... 63 be depressed, the former key 91 sets the totaltaking control disc 263 to position 1 where projections 390,391 obstruct downward movement of the feelers 280, 281 and thus cause line 1 to be selected for engagement as.described above. The downward movement of the pin 303 which would disable the feelers 280, 281 and so inhibit engagement of the totalizer line is prevented by a projection 392 in the total disc 263. Since, as stated above, the action of the totalizer-engaging spider 326, Fig. 12, is changed to total-taking timing, the selected totalizer remains engaged at 'the end of the first cycle of total taking. Towards the end of this cycle, the rocking of the total-control shaft 347 rocks a shaft 273, Fig. 14, counterclockwise to lift an arm 269 having a pin 268, which through a cam slot 277, Fig. 27, turns the total-control disc 263 one step counterclockwise. This moves the projection 392 clear of the pin 303 which can then move to disable the feelers 280, 281. Although the engaging spider is given an engaging movement prior to the return of the actuators during the latter half of the second total-taking cycle, the line 1 totalizer is, because of this disablement, not re-engaged with the actuators and the selected totalizer remains zeroized. This engaging movement is used to engage other lines to which the total is to be transmitted, as . described below. Sub-total taking. Movement of the total lever 95, Fig. 1, to the sub-total (read) position moves a cam 396, Fig. 14, which depresses a roller 397 to lift an arm 398 to disable the connection between the total-control shaft and the arm 269 so that the total disc 263 is not given the extra step at the end of the first totaltaking cycle. The feelers 281, 281 are thus not disabled and the selected totalizer is reengaged with the actuators prior to the return of the latter to re-enter the amount therein. Transmitting totals. Totals taken from totalizers 1 ... 8 of line 1 are accumulated in totalizer 7 of line 4. When any of the said line 1 totalizers 1 ... 8 is to be cleared-, the corresponding key 55 ... 62, the line-selecting total key 91, the total lever 95 and the key 88 for the receiving t
