Abstract: 260,317. Last, J., and Accounting & Tabulating Corporation of Great Britain, Ltd. June 24, 1925. Statistical machines. - In a record-card-controlled machine such as described in Specification 26896/13, means are provided whereby certain of the type-carrying members are employed on a change of designation occurring to effect automatically the control of the machine for total-taking purposes. As shown in Fig. 1, the type sectors 1 used for designation purposes are pivotally mounted on a shaft 7f and each has an extension 2 to which is pivoted a pawl 3 with teeth 4, 5, actuated during the movement of a retractor bar 9 connected to the main operating shaft 3<A>, to force the tooth 4 into engagement with a corresponding rackbar 6, the tooth engaged depending on the stop-finger 135 raised. The rack-bars 6 are mounted on plates 7 pivoted on the shaft 7f and are held in set position by a tooth 16 on a lever 15 engaging the teeth of the arcuate part 14 pivoted to the pawl 3. The plates 7 have extensions engaging a bail 89 mounted on arms 170 pivotallv mounted on the shaft 7f. So long as cards with the same designation perforations are passing through the machine the bail 39 is not moved, but when the first card of another classification is presented the arms 170 are rocked and through an arm 40 integral therewith, a link 41, Fig. 2, is depressed to actuate a bell-crank 42 so as to free a hook 45 on a second bell-crank 44 from engagement with a link 46 which is thereby permitted to move to the right, Fig. 2, when the stopfinger frame 132 is raised to rotate the shaft 49. At the same time the arm 51 of the ben-crank 42 rocks another bell-crank 78 to raise a link 80 and free a pin 90 on the lower end thereof from an arm 91 on a shaft 92 which, under the action of a spring 102 and slotted link 97 connected to a second arm 94 on the said shaft, is rotated to move the pin 99 on an arm 100 to the end of the slot 98 thereby preventing movement of the picker-bar 106 that is normally actuated by a double-armed lever 104, plunger 108 and cam 110, so as to stop the feed during the total-taking operation. The tooth 16 associated with each of the sectors 1 is normally held disengaged by a locking-link 26 engaging the end of a lever 23 in contact with the lever 15, the lever 23 being held in position by pins 22 under the control of manual levers 20. To disengage the teeth 16 of the designating sectors for effecting the new setting on a change of designation, the shaft 17 is provided with an arm 30 connected to a link 31 so that on the restoring of the link 46 the left-hand end thereof. Fig. 2, rocks a shaft 61 and displaces a link 63 having a pin 72 adapted to rock the link 31 and thereby position a pin 70 thereon into the path of an operating member 67 on the shaft 3<A> to effect the depression of the link 31 and the rocking of the shaft 17 to release the teeth 16. The shaft 49 is connected with mechanism controlling the "0 " stops, but the shaft is only permitted to rotate if the hook 45 has been removed as described above. The raising of the " 0 " stops is to prevent movement of the designating sector during the completion of the transfer operation in the adding sectors. The control of the engagement and disengagement of the totalizers during the total-taking operation is effected by the usual cam-plate 8<E> that is connected by a link 137 and arm 136 to the shaft 61. During this operation the pin-box is not raised, means being provided to disengage the raising cams 154. The cams 154 are loosely mounted on the shaft 111 and are coupled thereto by arms 150, Fig. 7, through clutch members 151, 152 and roller 153. On the rotation of the shaft 92 a lever 157 carried bv an arm 156 thereon engages a stop 160 on a lever 161 so as to throw the end 164 into the path of the roller 153 to disengage the clutch. On the feed cam 110 is mounted a pin 166 adapted to engage a pin 165 on the end of the lever 157 to release the lever 161 and throw the clutch in. The extension-rods of the sensing-pins operating the fingers 135 may be cranked or off-set so that a column may cooperate with any type sector and in cases where " double punching " is employed the extensionrods are adapted to co-operate with two type sectors. Specification 201,221 is also referred to.
