Abstract: 524,088. Selective punching - machines. NATIONAL CASH REGISTER CO. Jan. 21, 1939, No. 2140. Convention date, Jan. 21, 1938. [Class 31 (ii)] [Also in Group XIX] A perforated record-controlled calculating machine having means for sensing and comparing identifying data in several records, e.g., ledger card and pass books, and for initiating or preventing subsequent machine operation according as agreement or disagreement is determined, is provided with at least one totalizer (top or balance totalizer 425, Fig. 1), a keyboard 424 for manually setting up (or withdrawing) additive data to be entered subsequently into the said totalizer, means (code plates 296, Fig. 29) settable under control of one of the records (the ledger card, Fig. 3) for entering additive data into the totalizer, and common differential mechanism 247, Fig. 1, for transmitting to the totalizer 425 the setting of the keyboard and the setting of the code plates. A ledger card 135, Figs. 3 and 12, and a pass book 136, Fig. 4, each perforated in code at 131 with the account number, are inserted into a cash register of the Shipley type (Specifications 223,939 and 224,244, [both in Class 106 (i)], are referred to), the deposit is added on keys 424, Fig. 1, release key 89, Fig. 6, is depressed, and the account perforations are read by pins 153 in a preliminary machine cycle. At disagreement, one or more horizontal bars 171 are rocked and the machine remains locked. If the two account numbers agree, the machine proceeds automatically to perform five machine cycles as follows : (1) the deposit (entered by manual keyboard 424, Fig. 1) is added into a top or balance totalizer 425, Fig. 1, and into a rear totalizer 426, the deposit is printed on the ledger card and passbook, and the old balance holes on the ledger card are read by pins 360 ; (2) the old balance is entered into the balance totalizer 425 and a front totalizer 427 and is printed on card and book ; (3) various mechanisms are positioned and reset; (4) the new balance is cleared from the balance totalizer 425, printed on card and book and passed to a temporary storage device (wheels 483,489, Figs. 1 and 40); (5) the new balance is transmitted from the storage to the rear totalizer 426 and punched in the ledger card. The folding passbook is shown opened in Fig. 4, the two-denominational account number 47 being punched in a four point code with the two denominations in line at 131. Selective punching mechanism.-In the first half of the fourth cycle the top, or balance, totalizer 425 is reset, the differentials and the beams 473, Fig. 1, are set accordingly and position the gears 483 and 489, Figs. 1 and 40. At this point the new balance, from totalizer 425 is stored in these gears. In addition to setting the printing wheels, the gears 483, 489 differentially set gears 541, 542, Fig. 30, one for each denomination. Rigid with each gear 541, 542 is a set of four code discs, Figs. 35-38, coacting with four punches 547 so that for each setting of the wheel 541 (or 542) for a different digit, a different combination of high spots on the code discs is opposite the line of four punches. Shaft 543 carrying the code discs is mounted in a cradle 544 which is subsequently moved down so that high spots opposite punches depress selected punches to perforate in code form the digit of the new balance. Cam-controlled means move cradle 544 left and right to engage and disengage the wheels 541, 542 with wheels 483, 489 at the correct times. In Figs. 35-38, only disc I, Fig. 35, has a high spot opposite a punch. This represents "O" see Fig. 17. The punches are mounted in a basket 604 which is held yieldingly in raised position. Transferring new balance to rear totalizer 426. -Each code disc, Figs. 35-38, has two sets of code steps, one set for actuating a punch as above, and the second set which, when cradle 544 carrying the shaft 543 (see previous paragraph) is raised selectively, raises a plate 599 to set the corresponding pin-box plate 361. The new balance, thus transferred to the pin-box, is then transmitted to code slides 296, Fig. 29, which coact with auxiliary key locking plate 262, Fig. 27, and keys 258, Fig. 28, to set the new balance on the differentials. The rear totalizer 426, Figs. 1 and 23, is engaged with the totalizer by the mechanism of Fig. 23 and the new balance entered into the rear totalizer. The bodily movements of the code discs, Figs. 35-38, with their cradles 544, Fig. 30, to transfer and punch the new balance, occur during the fourth and fifth of the five accounting cycles and takes place in six stages, viz, the cradle 544 is moved (1) to the left (Fig. 30) to disengage gears 541, 542 from gears 483, 489 (see previous paragraph), (2) up and down again to set plates 599,361, (3) to the right to re-engage wheels 541, 542, and 483, 489 (4) to the left, (5) down and up again so that the code discs set the punches, and (6) to the right to re-engagement of the gears. Specifications 608/06, [Class 106], 8119/15, [Class 106 (i)], 280,828, [Class 100 (iv)], and U.S.A. Specification 923,857 also are referred to.
