429,805. Statistical machines. COMPAGNIE DES MACHINES BULL, 92<bis>, Avenue Gambetta, Paris. April 14, 1934, No. 11337. Convention date, April 15, 1933. [Class 106 (i)] In a perforated record - card - controlled machine the perforation-reading device reads the cards mechanically in motion and consists of a toothed wheel 40 rotated synchronously with the card feed so that the successive teeth touch the successive perforation-positions in a card-column, this reading-wheel, when one of its teeth reads a hole, moving bodily towards the card 41 and thereby initiating adding, printing or another control operation. When the reading wheel 40, Fig. 2, sinks on reading a hole it still remains in mesh with its driving wheel 60. When a hole is read, wheel 40 falls and its carrying bell-crank lever 45 rocks about pivot 46 so that pin 48 carries nose 58 of link 51 to the left into the path of a ratchet 62 which is constantly rotated counterclockwise. A ratchet tooth thereby raises link 51 to rock bell-crank 65 clockwise. Almost immediately, slope 59 on link 51 meets a roller 57 and link 51 is restored to the right to remove nose 58 and raise the reading wheel 40. Part 64 of ratchet 62 maintains the wheel 40 raised between cards. The rocking of bell-crank 65 (1) actuates cable 67 to rock the lever 69 counterclockwise and spring 110 rocks the freed lever 72 clockwise about pivot 78 so that wheel 77 rolls around wheel 76 to engage the counter wheel 87. Wheel 74, rotated synchronously with the card feed, then rotates wheel 87 until, at the time when " 0 " hole positions are read, a cam 109 restores lever 72 counterclockwise. Wheel 87 may carry a numeral drum. (2) Crank 65 causes the cable 68 to raise arm 70 and unlock a lever 73 which effects printing as described in Specification 380,474, [Group XVI]. In a modification, Fig. 3, a card-reading wheel 159, similar to wheel 40 of Fig. 2, is rotatable on a three-armed lever 161, 163, 172 pivoted at 162. At the moments that the wheel teeth read hole-positions, lug 173 is opposite gaps 174 of the ratchet 175. When a hole is read arm 161 falls, lug 173 passes into a gap 174 and the end 172 is no longer in the path of finger 177 pivoted at 178 to arm 179. Almost immediately, lug 190 on arm 179 falls into a gap 174 and arm 179 falls about pivot 180 so that latch 189 engages under the lateral shoulder 191 of an arm 192 which is pivoted at 193 and carries pivoted to it at 201 a link 200. Immediately afterwards, wheel 175 raises parts 190, 179, 189, 191 and the latter raises the link 200 which actuates control mechanism. The Specification as open to inspection under Sect. 91 describes also the following devices : In a modification, Fig. 2 (Cancelled), the wheel 40 of Fig. 2 is replaced by a single reading finger 20 which is retracted and released with bell-crank 22 by ratchet 25 so as to tap each perforation position. Transfer mechanism.-When an adding wheel 87, Fig. 3 (Cancelled), passes from " 9 " to " 0 " its transfer lug 93 depresses nose 96 and rocks lever 94, 99 to release a shoulder 103. Bell-crank 104, 109<1> rocks clockwise and its end 110 turns the next higher adding wheel one tooth when cam 114 depresses levers 106 and 109<1>. Subsequently cam 114 allows a spring 113 to raise the levers 106, 109<1>, 104 and a cam 146 relatches the shoulder 103 on arm 99. Zeroizing - mechanism.-At resetting, the wheel 436 rotates wheel 434 and counterwheel 87, Fig. 4 (Cancelled), until, when wheel 87 is reset at zero, a partial tooth 437 is opposite wheel 436 and the teeth of the latter cannot reach the tooth 437 to rotate the wheel 436. During normal adding, a toothless part of wheel 436 permits rotation of wheels 87 and 434 as shown. Total-printing.-A shaft 141, Fig. 3 (Cancelled), carrying a cam 142 and wheel 140 is rotated at total-taking. Cam 142 rocks the bellcrank 137 to enmesh wheel 135 and adding wheel 87, and subsequently the train 140, 139, 135 rotates the adding wheel 87 forwards one revolution. As the wheel 87 passes through zero its transfer lug 93 rocks lever 94 about pivot 95 and raises the tip 150 of arm 98 into the path of a ratchet wheel 117 which is geared to the total shaft 141. The next ratchet tooth rocks the tip 150 and arm 119 to the right so that arm 120 and latch 125 release the lever 246 to effect printing. Specification 380,474, [Group XVI], is referred to. Comparing holes in successive cards. When the latch 189 raises the part 191 and link 200, the part 191 rocks a latch 234, Fig. 4 (Cancelled), counterclockwise to release a pawl 231 which latter thereupon engages the constantly running ratchet 228. Pawl 231 is .pivoted to a member 229 which thereupon rotates counterclockwise with the ratchet 228. When member 229 reaches a roller 206 on lever 203 it rocks the latter counterclockwise about pivot 204 so that its extension 202 pushes the top end 208 of link 200 to the left. Assuming that two successive cards are similarly punched in the column being read then the member 229 latched by the first card rocks the end 208 to the left exactly at the moment that the hole-reading of the second card causes link 200 to rise. If successive cards agree, therefore, link 200 raises part 261 and lever 218 to release the lever 215. For disagreeing cards, link 200 rises idly past the part 261 or is rocked left without rising. The released lever 215 is pulled by spring 213 against a pin 222 on a lever 220 pivoted at 216 the lower end 252 of which is thereby raised to allow a lever 254 to rise into line with end 264 of a lever 265 pivoted at 266. Lever 254 is pivoted at 255 to a lever 256 itself pivoted at 257 and carrying a roller 258 controlled by a cam 259. When this cam rocks lever 256 clockwise, lever 254 moves to the left and rocks lever 265 counterclockwise so that cable 269, attached to lever 265, is pulled to the right. Cable 269 is connected so that the machine continues to run normally only if the cable is pulled to the right for each card. This classification comparison on successive cards may be effected on more than one column of each card. For a group number of, say, six denominations there would be six wheels 159, six ratchets 228 &c., but only one cable 269. Cable 269 may control total-taking and zeroizing as in Specification 422,668. A second member 229A is provided with a pawl 231A for action alternately with member 229. Lever 254 may be so arranged that it is normally opposite the end 264 and is removed therefrom for agreement between successive cards. A rise of cam 167 coacts with roller 166 on arm 163 to hold the reading-wheel 159 raised between cards. Column selectors. For manually preset control, pegs 250 may be placed in radial slots 249 of disc 248 rotating with cam 259. If a peg 250 rocks roller 207 on lever 203, 202 to the left at the same moment as link 200 is raised by the card-reading, the cable 269 will be pulled to the right as in the case of successive cards agreeing, described above. The parts shown in Fig. 5 (Cancelled) for this manual selection or for the above automatic comparison, are repeated for each column of the cards used for this purpose. No-card control. Disc 407, Fig. 10 (Cancelled), rolls on the edges of cards and when the last card has passed, bell-crank 406, 411 rotates counterclockwise, pin 48 on arm 411 moves a tooth 58 on link 51 into the path of tooth 420 which thereby lifts link 51 until roller 57 swings it to the right. Link 51 in rising, actuates cable 421. This prevents total printing and zeroizing, cable 421 acting upon a slide inserted in total-taking mechanism as in Specification 422,668. A schematic arrangement is shown in Fig. 13 (Cancelled) in which the cards are first read by one or more toothed wheels W similar to that of Fig. 3, and then by electric reading brushes B which are employed for actuating adding and printing devices as set out in Specification 380,472. In the mechanical reading section, a cable 269 on a rod is connected, for example, to the total-taking mechanism as set out in Specification 422,668. In the electrical reading circuit, a card hole energizes the magnets 423, 424, which unlatch respectively a lever 245 (equivalent to lever 72 of Fig. 2) of the counter and a lever 246 of the printing mechanism. This subject-matter does not appear in the Specification as accepted.
