Abstract: 1,163,445. Selective printing. ING. C.O LIVETTI & C. S.p.A. 29 Sept., 1966 [1 Oct., 1965], No. 43490/66. Addition to 1,028,605. Heading B6F. [Also in Division G4] An adding or like machine similar to that described in Specification 1,028,605 includes, pairs of differentially movable actuators and a type wheel associated with each pair of actuators, the wheels being mounted on a frame which is movable between two positions in which one or the other actuator of each pair is connected with the associated type wheel, one type wheel being associated with a pair of actuators differentially movable, under the control of either the two lowest set-up orders on a set-up device or the lowest order of register, to represent in combination a non-decimal order comprising figures higher than nine, a first actuator of said pair being connected by connecting means to a sensing member so as to sense the lowest order of the set-up device, the connecting means being disabled by a control element operable through intermediate means by a cam portion of the second actuator of the pair when the second actuator is displaced from its zero position, whereby the first and second racks represent in combination the non-decimal order. The machine illustrated is for use in the British Currency system and the first and second actuators are a rack 35 and a slide 29 for the units and tens of pence, respectively. The rack 35 is associated with a pair of twelvetoothed pinions 38. Amounts to be printed are set up in columns of a pin carriage 5. The connecting means comprises levers 36, and 44 coupled by a slide 42 carried by the lever 44 and having a slot 41 which receives a pin 40 on the lever 36. When printing amounts higher than ninepence, i.e. tenpence or elevenpence, the 1 stop-pin 7 in the respective column of the pin carriage is engaged by a sensing member 34 and the cam portion 70 on the slide 29 releases a lug 62 from stop 63 so that when cam 59 rotates the slide 42 is moved to disconnect levers 36 and 44. Printing sums less than tenpence.-The sensing member 47 senses the set-up figure and the rack 35 via a rack 50 appropriately positions the type wheel 52. The rack 35 is then returned to its initial position and the pence total is entered into the pinions 38. The frame is subsequently moved to engage the slide 29 with the rack 50 but as the sensing member 34 engages the zero stop-pin the type wheel 52 will print 0. Printing tenpence or elevenpence.-The sensing members 47, 34 engage the appropriate stoppins in the two lowest columns of the pin carriage and the levers 36 and 44 are movable independently. During a first machine cycle the lever 36 moves the rack 35 upwardly and the pin 40 engages projection 103 and moves slide 101 to release pin 91 from stop 94. Upward movement of the slide 101 is arrested when the pin 40 engages a projection 104. The rack 35 has then moved ten or eleven steps depending whether the sensing member 47 engages the 0 or 1 stoppin, and a 0 or 1 is set up on the type wheel. During the return of the rack 35 the value is entered into the register 38. The frame 19 is then moved to engage the slide 29 with the rack 50 and during a second machine cycle the slide causes a 1 to be printed by the type wheel. Transferring the total from the register to the type wheels.-During the first machine cycle the slide 29 moves upwardly one step, releases stop 62, and causes disengagement of levers 44, 36. The rack 35 moves upwardly and transfers the total in pinions 38 (if less than 10) to the type wheel. During the second part of the first cycle a lug 73 is released by movement of bails 75, 81 and comes into the path of shoulder 71, such that during the second machine cycle the slide 29 is stopped in the zero position, and the type wheel prints 0. For a total of 10 or 11 pence, slide 29 moves upwardly one step as before and the rack 35 moves upwardly and rotates the type wheel through 10 or 11 steps. Movement of the rack 35 causes pin 40 to engage the projection 103, and move the slide 101 upwardly, releasing the pin 91 from the stop 94. The pin 91 prevents the bail 75 from being fully rocked anticlockwise, and in the second machine cycle movement of the slide 29 through one step is permitted and the type wheel prints 1. For printing a decimal amount in a non-add operation a lever (106), (Fig. 3, not shown), is rocked clockwise causing movement of lever 66 clockwise and bringing shoulder 64 into path of the leg 62, thereby preventing actuation of slide 42 to release lever 36. Movement of the lever (106) and consequential movement of lever 66 release a tens of shillings rack 8<SP>1</SP>, and the tens of pence slide 29 so that rack and slide will transfer to the type wheel a decimal amount.
