Abstract: 753,063. Statistical apparatus. BRAUN, K. J. May 4, 1954, No. 12981/54. Class 106 (1). Punched record cards of irregular size are fed through a sensing apparatus by means of feeding and locating holes interspersed with the perforated data-representing holes. The apparatus comprises a delivery station, a card removal station, at least one operating station intermediate the delivery and removal stations, a first pin means for card feeding and locating to retain the cards in a given relation relative to one another, a second pin means to intermittently feed the cards to the operating station and accurately position the cards there, and a third pin means adjacent the removal station to ensure the same card sequence for the cards as they leave as that at the delivery station. Record cards C are fed seriatim from a magazine M, Figs. 2, 11, by means of a picker knife or sliding plate 17 in known manner. The cards are positively held in a stack S by pins 26 supported on a block 16. The cards are fed from the magazine M or delivery station DS to spaced feeding pins 10. These pins are carried on a reciprocating pin carriage P. The bars 40, 41 and pins 10 are moved forwardly in a horizontal plane, upwardly in a vertical plane, rearwardly in a horizontal plane, and downwardly in a vertical plane during each card feeding cycle. Forward and rearward movement is imparted to the bars 40, 41 by a shaft 46 by means of a lever 47 received by notches 48 in the bars. The bars 40, 41 are given vertical movement by means of a rack lever 54, the rear end of which has a shaft 55 riding in slots 56 formed in short arms 57 formed in the bracket member 45. The cards are positively ejected at the removal station RS by means of pins 26 co-operating with card stripper bars 62. Whenever lever 54 is rocked clockwise about its pivot 61, the stripper bars 62 will be elevated. The card C is shifted from the pins 10 adjacent the station RS and transferred to the pins 26 so that the sequence is positively maintained. At the beginning of a card feeding cycle the parts are as shown in Fig. 14. The card feeding pins 10 are as shown in Fig. 14. The card feeding pins 10 are elevated in their extreme rearward position and the stripper bars 62 are in lowered position. As the cams 66, 67 are rotated clockwise, Fig. 2, the pin carriage P will be lowered to engage the feeding pins 10 with the locating holes 28 in cards C2, C3, and C4, Fig. 14, and the stripper bars will be raised. Further rotation of the cams causes the pin carriage P to be moved forward, further movement of the cams causes the pin carriage to be moved upwards to withdraw the pins 10 from the cards C3, C4, and the stripper bars 62 to be lowered, to transfer card C2 from its pair of pins 10 to a set of pins 26 projecting upwardly from block 16. The perforated information in the cards C2, C3, is sensed by Bowden wires in stations PSA and PSB. The cards C are not held by the pins 10 during sensing. Further rotation of the cams 66, 67 returns the pin carriage P from its lefthand position (Fig. 17, not shown) to its position in Fig. 14, thereby completing one card feeding cycle of the machine. Specification 711,565, [Group XVI], is referred to.
