Abstract: 558,218. Calculating apparatus. REMINGTON RAND, Inc. July 24, 1942, No. 10398. Convention date, July 24, 1941. [Class 106 (i)] An accounting machine, having totalizers in which the transfer of the tens is effected by moving a wheel along its actuator relatively to the other wheels, is provided with means for splitting the totalizer and for disabling portions of it so that the actuators associated therewith may be used for printing text including alphabetical text or other designatory matter. The totalizer wheels are carried by individual supports with a common operating member to move them bodily towards and away from the actuators. Each support is so mounted that it can be manually disconnected from the operating member and reconnected thereto in an ineffective position. The invention is shown applied to a record-card controlled machine of the type described in Specifications 522.562 and 555,823. The card handling section is similar to that described in U.S.A. Specification 2,044,119 and controls the extent of movement of racks 47, Figs. 5 and 6, for actuating the totalizers. These actuators each carry a series of type elements including numerical and alphabetical type. The totalizers are arranged in desired positions in two tiers on bars 54, 55. The totalizer wheels 56 are each journalled in a lever 60 pivoted on a comb bar 61 and guided on comb bars 63, 64 and 65. When the wheels are in mesh with the actuators 47 the levers 60 are individually urged to spring upwardly at their rear ends. Each lever is normally held down by a transfer dog 66 which is connected by a link 68 to a transfer pawl 7U that co-operates with a transfer tooth 72 on the next lower wheel so that in passing from the 9 to 0 position the dog will be rocked to permit the lever 6U to rise and carry the wheel along its actuator to effect the transfer. The usual detent levers 74 are provided to hold the wheels when out of mesh. The comb bar 61 is secured to the cut out portion of a rod 80 with eccentric trunnions 82 journalled in bearings in a base member 83. A link 90 is pivoted to the member 83 and to the plates 84 of the totalizer frame. The totalizers are moved into and out of engagement with their actuators by rocking shafts 120, 121 which are operativeiy connected by an arm 132, a compound link 127, 128, a lever 125 and a link 122 to levers 95 secured to the ends of the rod 80. The levers 95 are also connected by links 97 to lever 98 carrying a bail 100 which co-operates with the detent levers 74. The bail 100 also co-operates with levers 101 carrying a bail 102 that overlies the levers 60. Each lever 6U has pivoted thereto a bell crank 105 with a roller underlying a channel bar 110 secured to a cross bar 111. A cross bar 111 is provided for each tier of totalizers and is connected to operate in a known manner to effect the return of the displaced levers 60, after transfer, to their normal position. Disabling and splitting the totalizers.-The compound link section 128 is formed with a slot 134 which can be partly covered by a pivoted interponent 135 when in the active position so that the stud 133 on the arm 132 is effective to transmit a movement to the levers 60. The interponent is influenced by a spring 137 which tends to hold it in the active or disabled position as defined by lugs engaging a pin 139. For splitting or disabling desired denominations means are provided whereby the appropriate levers 60 may be set bodily forward of their normal positions. For this purpose each lever 60 is provided with two pivot studs 62 and when the forward end is lifted and the lever drawn forward the rear stud is seated in the notch in the comb bar 61. Accidental displacement is prevented by a locking flap 140. The forward movement of a lever 60 rocks, through the link 68, the transfer dog 66 of the next lever to the left. The inoperative levers 60 are held down by the provision of co-operating lugs or ears 144, 145 on adjacent faces of the levers. Total-taking operations.-To lock the levers 60 against rising during these operations a bail 146 is rocked forwardly from its normal position, Fig. 6, to stand over the levers. One of the arms of the bail is connected by a link 151 to a bell crank 152 that is operatively connected to one of the operation control shafts which may be the "credit balance shaft" 154. As shown the bell cranks 152 are connected by a link 153 the lower bell crank having a pin and slot connection with the link 156 while the link itself has a pin and slot connection with the arm 155 on the shaft 154. The other mechanisms that co-operate during the various total taking operations are similar to those described in the abovementioned Specifications.
