Abstract: 752,776. Accounting machines. NATIONAL CASH REGISTER CO. Nov. 15, 1954 [Dec. 23, 1953], No. 33005/54. Class 106 (1). In a multiple-totalizer machine, totalizer selection is effected automatically according to the value of an amount set up. The invention is applied to a payroll accounting machine, e.g. as described in Specification 605,926, and provides means for automatically selecting the appropriate one of three totalizers for accumulating an employee's current wage according to whether his earnings to date, picked up in a preceding operation, are below 3000 dollars, 3000 to 6000 dollars or 6000 dollars and over, where such classification of total wages is required by the employer for tax purposes. During each pay cheque transaction, the employee's earnings to date are first set on the amount keys 61, Fig. 1, and the machine operated by means of the fifth key in row 2. The current earnings are then set and the machine operated by means of the ninth key in row 4. In this operation, the transaction differential of row 4 is arrested in its ninth, eighth or seventh position according to the previously entered earnings to date regardless of the ninth key being the operated key. These three positions of the transaction differential select three corresponding totalizers on the front line of the usual three lines of totalizers. Associated with the row 4 transaction differential are a pair of solenoids 290, 291 (solenoid 290 only shown in Fig. 3) each connected to a pivoted stop, as 277, adapted for engagement with a respective step 272, 274 formed in an apertured disc 270 integral with the differential arm 228. The steps 272 and 274 are located in the eighth and seventh positions respectively Relays 363 and 359 control energization of the two solenoids and themselves are controlled by selector switches 163 associated with the 100 dollar and 1000 dollar amount banks. A further selector switch 163 is associated with the row 2 transaction differential and is effective upon setting-that differential to position " 5," during entry of the employee's earnings to date, to prepare an energizing circuit for the two relays 359 and 363. If the amount set in this operation is less than 3000 dollars, neither relay is energized and the transaction differential of row 4 moves to its ninth position upon operation of the ninth key in that row during entry of the current earnings. If the amount set is 3000 dollars and below 3600 dollars, a circuit is continued through the amount bank selector switch of the 1000 dollar bank to the relay 363, and this circuit is completed by closure of contact 352 at the appropriate moment in the earnings to date entry cycle, whereupon relay 363 is energized and locks-up over contacts 380, 386, the solenoid 290 being energized with this relay. Consequently, during the ensuing current earnings entry operation, the stop 277 is effective and arrests the transaction differential of row 4 in the eighth position. Similarly, if the earnings to date are 3600 dollars or over, relay 359 and solenoid 291 are energized and the transaction differential of row 4 is arrested in its seventh position. A selector switch 363 is also associated with the 10,000 dollar amount bank to cause relay 359 and solenoid 291 to operate in the event of earnings to date reaching 10,000 dollars or over. The holding circuit for the operated relay and solenoid is interrupted at contacts 382 upon energization of a relay 391, which occurs when the differential of transaction row 1 moves to position " 1 " during the concluding cheque printing operation of the transaction. Specification 712,732 also is referred to.
