Feeling device for machines for interpreting perforated cards

Abstract

Abstract 285,437. Tauschek, G. Feb. 16, 1927, [Convention date]. Statistical apparatus. - In record-card-controlled machines the sensing mechanism, forinterpreting the perforations in the cards and for controlling the operation of a sorting device or counting mechanism, is constituted by a drum 4, Figs. 1 and 2, having radially displaceable pins 5 with lateral extensions 6 to co-operate with a segmental bar 8 having grooves 8<a>, 8<c> separated by a ledge 8<b>. The drum is mounted in front of a slotted plate 2 the slots corresponding with the perforated columns on the card 1. In operation those pins 5 which do not enter the perforations are pressed radially and are maintained in their inner position by engagement of the extensions 6 with the groove 8<c>. If the numerical value of the perforation is determined by its position in the column a device as shown in Fig. 4 is employed with the sensing mechanism to sort the cards. A card distributor 11 is operated by a cam 9 in synchronism with the feeding movement of the card in such a manner that the pin 5 operates the slide 12<a> to cause a pawl 12 to arrest the movement of a distributor at the moment it is over the appropriate pocket 10. A sorting device for cards wherein the numerical value is represented by a succession of perforations in one column is shown in Fig. 5. The projecting pins which correspond to the numerical value in their operative movement rotate a pinion 13 gearing with a rack 15 which itself operates through a segment 16 the distributor 14.
