Abstract: 722,117. Record card controlled printing. REMINGTON RAND, Inc. Feb. 27, 1952 [March 2, 1951], No. 5169/52. Class 100 (4). In a machine for interpreting perforations in a record card and printing the decoded information on an imperforate portion of the card, and in which automatic zero printing mechanism is provided whereby significant zeros not represented by perforations in the card may be automatically printed, further mechanism is provided whereby falsificationpreventive symbols, e.g. asterisks, are printed in all amount columns to the left of the highest significant figure, and in one or more columns to the right of the lowest significant figure. As shown, the decoding mechanism 24 (Fig. 4), printing mechanism and automatic zero control mechanism are substantially as described in Specifications 550,618 and 582,150, [Group XIX], modified to allow the printing of required asterisks. Thus, the lever 57 controlling the automatic zero stop 30 is made in the form of a bell-crank having an ear 80 (Fig. 6) at the free end of its horizontal arm. A hook nose 81 on a bellcrank lever 82 engages the ear 80 to prevent rocking of the lever 57. The bell-cranks 82 are pivoted on a rod 83 and are controlled by rods 93, the upper ends of which are engaged by one end of levers 104 pivoted on a rod 105, the other ends of the levers 104 having flanges adapted to be engaged by pins 101 themselves operated by fingers on the slides 26. Thus should one slide be raised by the perforation-sensing mechanism the nose 81 maintains the levers 57 locked in inoperative position so that the printing rack bar 37 is free to ascend to its uppermost position. This position serves to print an asterisk, the top stop 27 being modified so as to be projected if no permutation slides 26 are raised. Asterisks are thus printed to the left of the first significant figure. When the slides 26 are operated after sensing the first significant figure, the nose 81 is disengaged from the lever 57 and by means of couplers 95 all noses to the right up to a predetermined point are also disengaged, the machine operating when levers 57 are disengaged in the manner described in Specification 582,150, [Group XIX]. In the example given (Fig. 12), punches are used to produce the check number and amounts, only the remainder of the legends being automatically printed. As shown, the first significant figure when sensed causes slides 26 to be raised to disengage nose 81 from the appropriate lever 57 and also from the levers 57 corresponding to the columns 17, 18. In column 19 an asterisk is always printed. Columns 11-18 are connected through Y wires to columns 45-39 respectively so as to print the requisite number of zeros in the " not over " column. The printing devices in columns 45-39 are such that if a slide 26 is raised in columns 11-18 a zero is always printed in the corresponding column 45-39, but'if no slide is raised in columns 11-18 an asterisk is printed in the corresponding column 45-39. A rod extending across the forward arms of all the levers 104 is provided for manually disabling all the hook noses 81 if desired. Specifications 433,879, 522,512, [both in Group XIX], 522,562; 522,563, [Group XIX], 523,532; and 524,859, [Group XIX], are referred to.
