Filed: 1919-08-06
Abstract: 165,846. Peirce, J. R. Aug. 6, 1919. Statistical machines; transfer mechanism.- Relates to machines for taking statistical .data from perforated record cards, adding them on selected registers, printing them on serial lists, also for printing the totals from all the selected registers in order, and a sub-total or total of all amounts standing on the separate registers. The machine consists of a master section comprising Rectors 153, Fig. 1, loose on a main shaft 83. with racks for actuating grand and sub-totalizers 180, 181 and having a stepped edge 154 for receiving a differential setting under the combined action of a two-armed lever 155 engaged by studs 157 on slides 44 and of the pivoted plate 158, swinging on the shaft 83, which carries the pivot of the lever 155 and is itself positioned by meeting the offset end 160 of one of the slides 44. This combination enables the ten digit values to be obtained by various combinations of holes in a column of four, and the four slides 44 are operated by holes accordingly in the record cards. The cards pass along this face of a plate D, Fig. 3. through which the feeler pins are guided, and the pins carry studs 43 to engage levers 42, the other ends of which engage pins on the slides 44. The four levers 42 are pivoted on a shaft 43a. The addition data thus pass to the numerical sectors 153, which add them on the totalizers 180, 181 of the master section and carry type sectors 168 for printing them on the normal list, and also by means of links 177, levers 178, and auxiliary shafts 173 - - 176, arms 182, Fig. 2, and links 183 pass them on to toothed rings 187 which add them on to appropriate registers. The registers are selected by notches in rings 186 similarly actuated from rackless sectors like the sectors 153 controlled in a like manner by slides 61, Fig. 3, actuated by levers 45 from feeler pins. These pins coact with the classification perfora. tions in the card and, as shown, the machine is arranged for one or other of a pair of selective classifications to take control corresponding to sets of levers 45, shown in active, and 46, shown in inactive position relatively to studs 49 and 50 in the feeler pins respectively. These are set by manipulating a slide 51 which by a linkage 56, 53, 54 and bell-cranks 52, 59 disables the lever sets 45, 46 alternatively. Each register is controlled by five wheels : a supplemental throw-off wheel 185 to disengage the register immediately after its actuation; a selecting wheel 186 to choose the register; a set of actuating wheels 187 up to the required denomination; a main throw-off wheel 188 for disengaging the registers; and a resetting wheel 189 for restoring the transfer parts. The wheels have radial arms and are loose on the main rock-shaft 83. A spring 191 restores each supplemental throw-off wheel 185 which is positioned by offsets 190, 192. The wheel 189 operates during the first part of a cycle and is controlled by a spring 196 and stop 195. A hook 198 is provided for each registering wheel 187, to'hold it during the first of the two cycles necessary to perform the totalling operation, thus preventing them returning to the minus-one position. These hooks are rocked into active position by limbs 290, 287, Fig. 5, and shaft 246 from the total key 242. The register wheels are carried on spindles mounted in arms 205 keyed to spindles each 206 fast with .an arm 207, Fig. 2<a>, to which is pivoted an arm 210 with a pin 211 adapted to bear against an arm 208 carried by a sleeve loose on the epindle 206. A pin 209 on this arm engages a notch in a selector wheel 186 when appropriate. Such engagement allows the counter to gear with its operating wheel 187; the main throw-off wheel 188 having cleared the roller 222 on the counter carrying arm 205. The movement of arm 208 and sleeve on spindle 206, by means of a link 213, rocks a spindle 215, Fig. 2b, to remove stop-arms 217 from the transfer hooks 202 allowing them to take position in the path of pins 203 on the higher denomination wheels 187. When tripped by transfer pins on the register wheels engaging arms 200 on them, these hooks free the pins 203 on the higher actuators 187 and allow an extra unit movement in the known manner. Arms 216, 217 on the spindles 215 ensure the action or inaction of the transfer parts as controlled by the selection of the register. The transfer parts are reset by the wheel 189 engaging a roll on a lever 197 normally locked out of action by an arm 220, Fig. 2<c>, but released from the latter by the spindle 206, arm 218, and pawl 219 when a register is moved out of operative position. A yoke 221 on the spindle 201 lifts all transfer hooks 202. The successive cards are presented to the pins by a rocking shaft 28 actuated by a link 32 and lever 33 from a cam 34. The sectors 153 are raised by a yoke bar 85, Fig. 1, carri,ed on plate 84a fast on the shaft 83 which has an arm 227, Fig. 4, rocked by a toggle 228, 229 actuated by a crank 223. An arm 233 fixed on the shaft 226 thus rocked carries a spring pawl 234 to engage pins 235, 236 on a lever 237 pivoted with friction grip at 237<a> and carrying a coupling Y-shaped slide 238 for engagement with one or other arm on a shaft 174<a> which controls the throwing into gear of registers and actuating segments. By this means the timing of such gearing is reversed, in the usual way, to enable the registers to set the segments to print totals therefrom. Printing totals and sub-totals.-The total-key 242, Fig. 1, on depression rocks a shaft 246 and a lever 256, thereby through a link 272, putting a hammer trip actuating link 270 into engagement with a pin 271, also through a link 257 putting a hammer resetting link 258 into engagement with a pin 261 on the main rocking plate 84<a>, this link also operating a feed-pawl through a link 260. The key also by means of a yoke 254, 255 disables the ordinary differential setting mechanism. In this way a single register total may be printed, but a preferable alternative arrangement, shown in Fig. 5, causes printing in succession from all the registers. The registerselector control shafts 175 have arms 285, 286 with offset ends to engage a pair of stepped discs 283, 284 which can be rotated by a pawl 281 on an arm 277 rocked by a crank-pin 276 from the main shaft 83. Normally, the arm 277 is held out of action by a pawl 291. This is freed, however, on depression of the total (or sub-total) key through the shaft 246, links 287, 289, 290, the linkage being latched until the whole series of registers have printed totals and a pin 308 on completion slides a link 305 to reset the shaft 246. Since a double turn of the main shaft 40 is necessary to print a total, an account of the engagement of registers and differential segments for setting type, alternative action of the levers 285, 286 is prevented by a hook 2, the tail of which has a pin' 5 to be caught by a shoulder on a lever 6 which is alternatively hit and missed by a pawl 3<a>, Fig. 5a, on actuation thereof from the shaft 1<a> rocked by a cam 2a, Fig. 4, on the main shaft. This mechanism is also under control by the total key-operated linkage and a catch 1. A sub-total key may be fitted in addition to a grand-total key such as controls the operation described above. The grand and subtotal keys 298, 240, Fig. 6, are fitted with a sector 295 with notches to select grand .or sub-totalizer, the sub-total key being detachably connected by a hook 299 and link 300 to the sector, allowing the link 305 through the shaft 304 and arm 301 to disconnect the hook and link after the completion of the series of totals from the registers and permit printing of the sub-total. Specification 166,056 is referred to.
