Abstract: 598,943. Statistical machines. REMINGTON RAND, Inc. Jan. 10, 1946, No. 965. Convention date, Dec. 7, 1944. [Class 106 (i)] A machine for handling master and detail records, and including a comparing means for sensing agreements or disagreements between statistical data on such records comprises separate record conveying means for passing master and detail records to a common receiving pocket, deflecting means individual to each of the conveying means to be engaged only by records conveyed thereby, each of said deflecting means being arranged when operated to prevent the passing of records to said common receiving pocket, and actuating means operable under control of the comparing means to operate both of said deflecting means. The invention is an improvement in the type of statistical machine described in Specifications 544,750, 546,590, 546,603, 546,604, [Group VIII], and 546,605 and concerns the modifications necessary to such a machine when an additional receiving pocket, called an interfile pocket, is provided to receive either or both master and detail cards as determined by the setting of two independent control mechanisms as described later. As in the previous cases, the control cams are carried by a sleeve 600, Fig. 5, arranged to be actuated in known manner according to whether the result of the comparison between master and detail cards is agreement or non-agreement. After leaving the master card sensing chamber, master cards are passed by ejector rolls 52, Fig. 13, over a table plate 53 to feed rolls 55 from which they may be fed into an eject pocket 26 or over a second set of feed rolls 57 from which they may pass to a '' receiver " pocket 25 or over a third set of feed rolls 174 into an interfile pocket 140. Detail cards may pass from their sensing chamber to " eject pocket 28, Fig. 14, or to " receiver " pocket 27 or " interfile " pocket 140. Between the master card feed rolls 55 and 57 there is a deflector 73, Figs. 13 and 20, which is normally spring-urged to a horizontal position, but which may be urged to an inclined position to deflect master cards to eject pocket 26. The deflector 73, Fig. 6, is urged to its horizontal position by a spring 75 connected to a bell-crank 76 provided with a stud 77 engaging a notch 78 on a downwardly extending link 80 connected to an arm 81 on a rock-shaft 82 which carries a vertical arm 83 co-operating with a control pin 85 of a horizontal link 86 connected to a bell-crank 87 which carries a roller 92 coacting with a cam 780 on the sleeve 600. The arrangement is such that when the cam 780 is actuated, in known manner in dependence on the sensing result, the roller 92 engages the high dwell of the cam 780 and through the above linkage rocks deflector 73 to its inclined position. Between the detail card feed rolls 55 and 57 is a deflector 93, Figs. 7, 14 and 20, carried by a shaft 94 to the end of which is fixed a bellcrank 95 connected to a horizontal link 96 connected to a bell-crank 122 which carries a roller 125 co-operating with a cam 126 on a shaft 127. Bell-crank 95 is urged counterclockwise to urge the deflector 93 open, but is retained in the position shown in Fig. 20 by a latch plate 98 having a notch 102 engaging a latch 104 connected by a link 106 to the bellcrank 95. In order to control the position of the deflector 93 in accordance with the action of the comparing mechanism, the latch plate is provided with a roller 107, Figs. 7 and 20, which co-operates with a pawl 110 slidably mounted in a settable link 112 adjustably secured to a forwardly extending link 116 connected to an arm 117 carried by a sleeve 118 rotatable on the rock-shaft 82. The sleeve 118, not shown, also carries a vertical arm 120 which co-operates with the control pin 85 on the link 116 in such a way that when the bellcrank 87 is rocked by the cam 780 the latch plate 98 is rocked counter-clockwise in readiness to allow the deflector 93 to open. This opening is deferred, however, till the next cycle to allow the detail card to pass through the punch chamber when by the action of the roller 125 on the cam 126 latch 104 is disengaged from 'the notch 102 on the latch plate 98. A control lever 130, Figs. 5 and 20, is connected by a link 135 and the control pin 85 to the link 86 and as shown can be set in any one of three positions L, U and B. With the lever 130 in position '' L '' the control pin 85 is in its lowest position and co-operates only with the arm 120 to influence only the detail card deflector 93 as described above. With the lever 130 in position " U," the control pin 85 is in its intermediate position and co-operates only with arm 83 to influence the master card deflector 73. With lever 130 in position " B," the control pin 85 co-operates with arms 83 and 120 to control both master and detail deflectors 73 and 93 in co-operation with the comparing mechanism. The detail cards that pass over the deflector 93, Figs. 14 and 20, pass to feed rolls 57 from which they may be deflected down by a deflector 270, as described later, or over another set of feed rolls 150 from which the cards are fed until deflected downwardly by a plurality of deflector arms 158 into the path of a pair of feed rolls 162, each of which are resiliently urged against a belt 164 of a rotatable pulleywheel 165 from which the cards are passed to the " interfile " pocket 140. The master cards that pass over the deflector 73 pass to feed roils 57, Fig. 13, after which they may be deflected by a deflector 235 into the " receiver " pocket 25 as described later or over another two sets of feed rolls 174, 175 after which the cards its forward end to enable adjustment of the tension of the belts 164. The shaft 225 carries a gear 226 for driving the feed rolls 174, 175. The master card deflector 235, Fig. 20, is carried by a rock-shaft 236 and is normally spring-urged to an inclined position, but can be closed by forward movement of a bar 241 slidable upon studs 242 and co-operating at its forward end with a pin 245 on an arm carried by the rock-shaft 236. The rear end of the slide bar 241 is connected by a link 250 to a lever 251, the arm 252 of which is connected by a pin and slot to a vertically adjustable rack bar 254. The detail card deflector 270 normally spring-urged to an inclined position, is carried by a shaft 271 which carries an arm 272 which co-operates with a cam surface 275 on an extension 276 of lever 251 to close the deflector are deflected by the fingers 186 to a plurality of feed rolls 187 which co-operate with the belts 164. The cards then pass via feed rolls 196, Fig. 14, feed rolls 205, deflectors 158 to feed rolls 162 from whence they pass to the " interfile " pocket 140. Spring-urged skid rolls 190, 198 are provided to ensure a positive drive between the belts 164 and the feed rolls 187, 196. The feed rolls 187, 196 and the pulleys 165 are driven from a gear-wheel 210 which may selectively be brought into or out of mesh with the gear 65 of the detail card feed mechanism. Each belt is connected at its upper end to a pulley 224 on a shaft 225 carried by a frame 219 which is rockably mounted at 270 when the lever 251 is rocked counterclockwise. The rack bar 254, Figs. 7 and 20, is vertically adjustable, by rotating a knob 259, into any one of four positions as indicated on an indicator 282 and in combination with the first selective control mechanism operated by control lever 130 determines the operation or inoperation. of deflectors 235 and 270 by the comparing mechanism. The arrangement is such that when the rack bar 254 is in its No. 1 position, the lever 251 is so set that the slide bar 241 and the cam surface 275 are free from the deflectors 235 and 270, which are retained open by their respective springs. The three known sorting operations corresponding to positions " L, U and B " of lever 130 may be carried out. When the rack bar 254 is in its No. 2 position, the lever 251 is so positioned that the slide 241 and the cam surface 275 retain their respective deflectors 235 and 270 closed so that in the above three sorting operations the '' interfile " pocket takes all the cards, master and detail, that previously went to receiver pockets 25 and 27. When the rack bar 254 is in its No. 3 position, the deflectors 235 and 270 are retained closed as before and a roller 295 on the forward end of slide bar 241 moves the top end of the link 80 forwardty to disengage the shoulder 78 from the pin 77 so that the master card deflector 73 is not operated by the control pin 85. In the corresponding three sorting operations with lever 130 in positions " L, U and B," all master cards go to the " interfile " pocket 140. The slide 112, Figs. 7 and 20, is raised by a fork 300 on the rack bar 254 and pawl 110 is disengaged from the roller 107 so that forward movement of the slide 112 by the control pin 85 will not effect the latch plate 98 and' thus the deflector 93 is retained closed and all the detail cards will go into the " interfile " pocket 140. When the rack bar 254 is in its No. 4 position, the deflectors 235 and 270 are retained closed as before and the roller 295 on the slide bar 241 moves the link 80 further forward until a cam surface 302 thereon rocks the bell-crank 76 counter-clockwise, which against the action of spring 75 retains master card deflector 73 open. The latch plate 98 is urged counter-clockwise by the engagement of a roller 310 with a cam surface of a slide 304 carried by the slide 112. If, therefore, no movement is imparted to the slide 112 by the control pin 85 during the next cycle of apertures, the action of cam 126 on roller 125 will, as before, allow deflector 93 to be opened. If, however, the control pin imparts movement to the slide 112, the slide 300 is removed from contact with the roller 310 so that the latch plate 98 will prevent opening of the deflector 93. With the rack bar 254 in this No. 4 position, it will be seen that the three sorting o
