Abstract: 616,662. Statistical apparatus. REMING- TON RAND, Inc. Sept. 18, 1946, No. 28068. Convention date, Oct. 18, 1945. [Class 106 (i)] In a card-controlled accounting-machine of the type having a plurality of members differentially settable in data recording positions and means for controlling said members in accordance with variable items of data successively entered in the machine, a normally idle member is adapted to denote a constant item of data and is associated with means responsive to the actuation thereof to control the differentially settable members and with operating means to effect actuation of the normally idle member. The invention is applied to the type of machine described in Specification 555,823. The differentially settable type bars 3, Fig. 1, are positioned by vertical rows of stops 7 controlled by the permutation bars 8 normally settable by the sensing pins 11, through a translator unit 13 comprising Bowden wires 12 and pins 15, in accordance with the perforated data on a sensed card. To the upper ends of the Bowden wires 12 are joined at 32 another set of Bowden wires 18 which at their lower ends pass through threaded perforations in an angular plate 19, Figs. 4 and 5, and which are adapted to be actuated by a set of screws 31 manually inserted in perforations 29 in a plate 28 to represent a constant item of data, when said plate 28 is moved upwardly. The bars 8 are therefore settable either through the Bowden wires 12 in accordance with the movement of the sensing pins 11 or through the Bowden wires 18 in accordance with the representation of the manually inserted screws 31 in the plate 28. The plate 28 is carried between two links 24 connected by arms 25 to a rock-shaft 26 and by arms 23 to another rock-shaft 21. A link 36 having at its lower end a slot receiving under spring pressure a pin 37 carried by an arm on the shaft 21 is pivoted at its top end to an arm fixed to a hollow shaft supporting a rockshaft 45. A cam 52 loose on a front drive shaft 35 co-operates with a roller 51 on an arm 47 mounted on a stub-shaft 46 and through a link 48 and an arm 49 transmits movement to the shaft 45 which through the link 36, arm 38, shaft 21, arms 23, links 24 moves the plate 28 upwardly, whereupon the inserted screws 31 set their corresponding Bowden wires 18 and thereby the corresponding permutation bars 8. The cam 52 is integral with a cam 53 which carries a clutch dog 54 engageable with a notch in a clutch disc 55 fixed on the shaft 35. A trip arm of a bell-crank lever 57 mounted on the shaft 46 normally holds the dog 54 out of engagement with the disc 55 against the pressure of a spring 56. The cams 52 and 53 are retained in their normal positions by a roller 59 engaging a recess in the cam 53, said roller being carried by detent lever 58 also mounted on the shaft 46 and connected by a spring 61 to the bell-crank 57. When, as described in Specification 555,823, the " credit balance shaft " 62 is rocked counter-clockwise, it causes through an arm 63, pin 64 and a link 66 the rocking of the bell-crank 57 to allow the dog 54 to engage the disc 55, whereupon the cams 52, 53 rotate with the shaft 35. The arrangement is such that the cams 52, 53 are clutched to the shaft near the end of the idle cycle preceding the total-taking cycle. Since, as shown in the above Specification, the differentially set type bars are not actuated from the permutation bars during a total-taking cycle, there is provided a bell-crank lever 69 which is pivoted to a bracket 71 on a fixed shaft 72 and which upon the downward movement of the link 66 engages a pin 73 to hold the link 66 in its down position until at the end of the cycle following the total-taking cycle the pin 73 is released by the action of the cam 53 on a roller 75 carried by the other arm of the bell-crank lever 69, whereupon a spring 61 returns the bell-crank 57 to its normal position in which it disengages the clutch dog 54 from the disc 55. The return of the credit balance shaft 62 during the total-taking cycle is allowed for by the elongated recess 65. The push link 66 may be disabled by manually raising the link to the position where a pin 64 on the rock arm 63 engages a recess 76, Fig. 1, when it is desired that the plate 28 be raised at times other than in conjunction with the total-taking operation of the machine. For this purpose there is provided a push link 81 which at one end engages a pin 82 in the bell-crank 57 and at its other end is pivoted to an arm on the shaft 45. A lever 84 is pivoted to the link 81 and is spring urged to a position in which it engages the pin 82 and carries a roller 85 which engages the cam 53. A separate Bowden wire, not shown, connects one of the lower translator pins 15 with a pin directly beneath a plunger 89 connected to a rock arm 86 on the shaft 45. The arrangement is such that if the control hole is sensed the particular translator pin 15 will lift the plunger 89, the shaft 45 will be rocked and through the link 81, lever 84, pin 82, the bell-crank 57 will be moved to allow the dog 54 to engage the disc 55, whereupon, as before, the plate 28 is raised to set the bars 8 through Bowden wires 18. The lever 84 is returned to the normal position by the cam 53 through the roller 85 to move the bell-crank 57 to disengage the dog 54 from the disc 55. When the first controlling means are operating, the plunger 89 is raised until a recess 97 therein engages the pin 87 on the rock arm 86 in which position the plunger 89 is not operated by the translator pin 15 immediately beneath.
