Abstract: 351,086. Typewriters etc.; adding-machines. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A.-(Assignees of Bentzel, F. D.; 2nd Avenue, Detroit, Michigan, U.S.A.) March 25, 1930, No. 9494. Convention date, April 17, 1929. [Class 100 (iv).] Hammer-impression arrangements; column - printing arrangements; printing totals. - Printing - mechanism for a calculating-machine comprises means for printing different portions of a total in different positions and, preferably, also for printing the entire total in another position ; means for printing] ciphers or signs at the left of the first digit ; and means for preventing printing in higher orders associated with means under control of the total mechanism for printing ciphers in lower orders. The machine shown in Figs. 3 and 5 is particularly for printing on pay-cheques P, Fig 9, bearing the words "Exactly," " Dollars " and " Cents," the amount of the total in dollars and cents, and the complete total being printed behind those words. A ledger sheet S and a corresponding pay cheque may be printed during the same series of operations. Figs. 3 and 5 show part of a Burroughs adding- machine comprising banks of keys and typecarriers and associated hammers 715 driven by spring-urged levers 716 on operation of triggers 717 which are normally released by pawls 718 or are released prematurely to silence the hammers. Banks 1, 2 and 3, 4, 5 are employed for printing cents and dollars respectively, and banks 5, 6 are employed for printing the signs *, $ to prevent fraudulent alteration. The types for these signs are placed in the cipher position. Banks 7, X control operations described below. The triggers are connected to links 20 carrying latches 21 depressible by means of cams 18 on a shaft 17 geared to a rack 15 which is connected to a rocking yoke arranged in the path of rollers on the paper-carriage. The latches of banks 2, 7 are formed with a lug 30 and a shoulder 23 respectively for engaging a bail 24 rocked by cams 712, 40. The latches of banks 3, 4, 5 have studs 32 for engaging lugs 33 on the links of banks 4, 5, 6. The triggers of banks 1, 2 are connected by a pin 31. In printing on a paycheck, the machine is controlled in the following manner: (1) When the carriage arrives at position E, Fig. 9, the shaft 17 makes a half-turn, and the latches of banks 2-5 are depressed by the cams, the lug 30 and studs 32 being thereby set in the paths of the bail 24 and lugs 33 respectively. On operation of the machine, banks 3-6 print the amount in dollars and the signs *, $ on the paycheck, printing of cents being prevented since the triggers of banks 1, 2 are released prematurely by the bail 24. If the total does not include dollars, a step 36 on the lug 30 co-operates with a lug 38 on the latch of bank 3, and the hammers of banks 3-6 are released at the normal time to print ciphers and signs in the dollar space ; (ii) When the carriage arrives at position F, the shaft 17 makes a threequarter turn, and the cams 18 depress the latches of banks 2, 7, the shoulder 23 being moved into the path of the bail, and the lug 30 being released from a shoulder 39 on latch of bank 3. On operation of the machine, the hammers of banks 1, 2 are.released to print the amount in cents on the pay-check, and printing of dollars is prevented, the triggers of bank 7-3 being released prematurely by means of the bail and tails 9 on the triggers of tanks 7-4. If the total does not include cents, ciphers are printed in the cents position, the triggers of banks 1, 2 being released by means of a tail 9 on the trigger of bank X, which is released under the control of the means conditioning the machine for taking totals or sub-totals; (iii) When the carriage arrives at position G, the shaft 17 makes a quarter turn, the latches of banks 3, 4, 5 are depressed, and on operation of the machine the entire total is printed on the pay-check. If the total does not include cents, the shoulder 39 cooperates with the lug 30 to release the triggers of banks 1, 2 and thereby cause ciphers to be printed in the cents position. If the total does not include dollars, a step 37 on the lug 30 engages the lug 38 to release the triggers of banks 3-6 and thereby cause ciphers and signs to be printed in the dollar position. The machine is employed in the following manner for printing on a ledger sheet: when the carriage arrives at position A the machine is conditioned for subtraction, and a deduction is set by the keys. If the deduction is less than one dollar, cents are printed in the normal manner, and the shoulder 37 co-operates with the lug 38 to release the trigger of bank 3 and thereby cause a cipher to be printed to the left of the cents. If the deduction is for dollars only, the hammers in the required dollar banks are operated, those at the left not being affected, and the shoulder 39 co-operates with the lug 30 to cause the printing of ciphers in the cents position. When the carriage enters the B, C position the machine operates in the normal manner to print hours, and the amount, and add the amount to the register. When the machine enters the D position, the shaft 17 makes a quarter-turn, the latches of banks 3, 4, 5 are depressed, and the total is printed in the abovedescribed manner. Specifications 193,455, [Class 100 (iv), Typewriters &c.], and 285,885, [Class 106 (i), Calculating &c.], are referred to.
