Abstract: 452,978. Typewriters &c. FARRER, J. 0., 27, Chancery Lane, London.-(Reming- ton Rand, Inc. ; 465, Washington Street, Buffalo, New York, U.S.A.) Jan. 29, 1935, No. 2960. [Class 100 (iv)] [See also Group XIX] Type-wheel actions.-A recordcard controlled calculating-machine having type-carriers equipped with both alphabetical and numerical type arranged in successive zones is provided with main actuators for setting the type from the card reading and supplemental actuators which, when the type-carriers pass from the alphabetical to the numerical zone, are mechanically coupled to the main actuators, the supplemental actuators serving solely to operate accumulator counters and being coupled throughout the numerical zone and uncoupled when the type carrier returns to the alphabetical zone. In dealing with five-point code cards, each card having two fields, the five points representing a denomination are read by pins 15 which raise one or more rods 21 operating five bell-cranks 52 which set to the left a set of five code slides 41, 42, Figs. 1 and 6. The four slides 41 are arranged in pairs and are notched variably along the length of the slide and the slide 42 is notched uniformly so that whatever combination of holes in the five-point code is read the slides 41 are set to give only one set of four vertically aligned notches. If a notch in bar 42 is also in line with this set of four notches the corresponding bar 43 can rise vertically and fully. If a lug on bar 42 is opposite this set of four notches the bar 43 can only rise half the height of the notches in bars 41. There are sixteen vertically rising bars 43 and each has three lateral lugs 47 coacting with the code bars 41, 42. The appropriate rod 43 may thus rise one or two steps and arrest the shoulder 77 or the end face of the actuator 70 which is used to set the type sector 81. The latter each carry twenty-three alphabetic type at the top, Fig. 4, followed by nine numerical type, these thirty-two corresponding to the thirty-two positions of actuator 70 given by its shoulders and the sixteen rods 43. In a modification for a six-point code, the bar 42 is replaced by two bars of half thickness having uniform notches of one-third and two-thirds the height of the notches in bars 41 and the actuator 70 has two stepped shoulders in addition to its end face, thus giving forty-eight positions for actuator 70. Each actuator 70 has a latch 72 coacting with a pin 73 on a link 74 pivoted to a supplemental rack 92 operating the denominational wheel 91 of the totalizer 90. While the actuator 70 is moving left through the alphabetical zone, pin 73 rides on the surface 70a of the actuator. As soon as the latter passes from the alphabetical to the numerical zone, pin 73 drops into slot 72 and link 74 is pulled to the left with actuator 70 for the next and last nine positions. As soon as link 74 commences to move left, a pin 75 on it is forced down by a fixed cam 76 so that 72, 73 are held together. The time of engagement of wheels 91 and racks 92, according to whether item-printing or total-printing is to be effected, is controlled by known mechanism. British Specification 26896/13, [Class 100 (iv)], and U.S.A. Specification 1,780,621 are referred to.
